用于对纤维网进行开孔和拉伸的设备和方法 For web opening and the apparatus and method of stretching

技术领域 FIELD

[0001] 本发明涉及开孔纤维网材料以及用于对纤维网进行开孔和拉伸以形成此类材料的设备和方法。 [0001] The present invention relates to an apertured web material, and webs for aperturing and stretching apparatus and method to form such materials.

背景技术 Background technique

[0002] 专利文献中公开了用于对纤维网进行开孔,变形和/或拉伸的各种方法和设备。 [0002] Patent Document discloses a fibrous web apertures, deformation and / or stretching of the various methods and devices. 在利用开孔方法诸如滚刀开孔的情况下,难以产生具有间隔很小的孔的纤维网,其中这些孔在横向("CD")上具有所期望的宽度。 In the case of using a method such as opening RKA, it is difficult to produce webs having closely spaced apertures, wherein the apertures have a desired width in the transverse direction ( "CD"). 为了将孔行间隔成靠近在一起,可提供具有非常小的夹角的活化齿。 To close together into spaced rows of holes, it can be provided with very small teeth activation angle. 然而,这种方法会带来问题,因为所产生的孔在横向上不具有足够的孔宽度,甚至在高啮合深度(活化齿辊对配对环辊的干涉)下也是如此。 However, this method can cause problems, since the resulting hole does not have a sufficient width in the lateral bore, even at high depth of engagement (activation ring gear roll pair rolls the interference) under well. 所得的孔常常在纵向上伸长,从而导致狭缝样外观、低开口面积、和潜在的应力集中,从而在使用中导致撕裂。 Often resulting in the longitudinally elongated hole, causing the slit-like appearance, the low open area, and the potential stress concentration, leading to tearing in use. 当采用较坚韧的且更具抗撕裂性的纤维网时,狭缝样、低开口面积的孔的产生尤其是个问题。 When tougher and more tear resistance of the web, slit-like, to produce a low opening area of the hole is a particular problem. 圆化的或渐缩的热针开孔是常见的方法,但其具有需要配对辊具有更大的对准精度的缺点, 并且其通常导致更大的孔间距。 Rounded or tapered apertures hot needles is a common method, but it needs to have a counter roller having a greater alignment accuracy disadvantages, and which generally results in greater hole spacing. 圆化的或渐缩的热针开孔通常以较低的线速度进行。 Rounded or tapered apertures hot needles is generally carried out at a lower linear velocity.

[0003] 有可能对开孔纤维网进行柱式环乳制以拉伸它,但可能导致交替行的孔径尺寸, 因为孔不能够与后续的环辊拉伸工艺配准。 [0003] it is possible to perform column apertured web to stretch it dairy ring, but may result in a pore size of alternating rows, because the holes are not capable of stretching registration process with the subsequent ring roll. 由于基底的可变的铺展,难以在横向上将结构与随后的工艺对准。 Due to the variable spreading the substrate, it is difficult structurally and lateral alignment of a subsequent process. 柱式环乳制也可能显著地弱化纤维网,从而使得其更易于撕裂。 Column dairy ring may significantly weaken the web, making it easier to tear.

[0004] 希望产生一种具有离散的、间隔很小的孔的纤维网,其中这些孔与先前可能的孔相比具有较大的横向宽度。 [0004] having desirable to produce a discrete, closely spaced holes of the web, wherein the apertures may be compared to previous aperture has a larger lateral width. 需要一种在横向上更牢固因而在横向上不容易撕裂的开孔纤维网。 A need for a more robust in the transverse direction and thus is not easily torn in the transverse direction of the apertured web. 需要一种产生如下开孔纤维网的方法,所述开孔纤维网具有更大、更宽、开口更大的孔。 Follows a need for a method to produce an apertured web, said web having a larger aperture, a wider, larger pore openings. 还需要允许纤维网被开孔成具有孔的设备,所述孔在横向上具有所期望的较大宽度。 Also need to be open to allow the web forming apparatus having a hole, said hole having a desired width in the transverse direction larger.

[0005] 存在许多已知的用于产生具有脊和凹槽的纤维网的工艺,例如环乳制。 [0005] There are many known processes for producing webs with ridges and grooves, for example, dairy ring. 也存在许多已知的用于产生具有孔的纤维网的工艺,例如热针开孔。 There are many known processes for producing a fibrous web having a hole, for example, hot needle opening. 然而,难以产生波纹形纤维网, 其具有与特定孔图案对准的交替的脊和凹槽。 However, it is difficult to produce a corrugated fibrous web having alternating ridges and grooves are aligned with the particular hole pattern. 存在用于进行微开孔然后进行环乳制的工艺。 Exist for micro ring opening process then dairy. 然而,这导致不具有波纹的平坦的纤维网。 However, this results in having no flat web corrugations. 可经由在图案化带上喷气或喷水来形成具有脊和凹槽的纤维网(平坦条)。 The web may be formed with ridges and grooves (flat bar) via a belt or water jet patterning. 然而,与本文所述的发明相比,喷气或喷水是慢得多的工艺并且需要更多的能量。 However, compared with the invention described herein, or a water jet process is much slower and require more energy. 此外,所述脊不是中空的因而能够保持更多流体。 In addition, the ridge is not hollow, it is possible to retain more fluid.

[0006] 希望产生具有交替的脊和凹槽的纤维网,其中孔位于纤维网中的特定位置,例如, 位于凹槽中或位于脊中。 [0006] desirable to produce a web having alternating ridges and grooves, wherein the hole is located in a specific position in the web, for example, located in the ridge or groove. 需要一种包括对准的波纹图案的开孔纤维网。 A need for a pattern comprising corrugations aligned apertured web.

[0007] 这些均是本发明的目标;本文所述的实施例可实现这些目标的各种组合。 [0007] These are the object of the present invention; embodiments described herein may be implemented in various combinations of these objectives. 某个具体实施例可以但非必需地实施每一目标。 A particular embodiment may, but not necessarily implemented for each target.

[0074] 本发明涉及开孔纤维网材料以及用于对纤维网进行开孔和拉伸以产生此类材料的设备和方法,所述设备和方法克服了现有技术的缺点中的一者或多者。 [0074] The present invention relates to an apertured web material, and webs for aperturing and stretching apparatus and method to produce such materials, the method and apparatus overcome the disadvantages of the prior art in one or more than those. 拉伸或伸展纤维网是有益的,因为其使得能够通过在总体上减小纤维网的基重而降低成本。 Drawing or stretching the web is advantageous because it makes it possible to reduce costs by reducing the basis weight of the web in general. 通过在相同的工艺步骤中进行开孔和拉伸,在纤维网材料中产生更宽、更优选的孔。 By opening and stretched in the same process step, resulting in a wider web material, more preferably a hole. 此处,开孔和拉伸是在单一单元中以对准方式进行的,使得所述拉伸是在齿仍然渗入材料期间进行的,因此不允许孔在被拉伸时发生塌缩。 Here, the opening and the drawing is performed in an aligned manner in a single unit, such that the stretching is carried out during the teeth penetrate the material remains, therefore do not allow collapse occurs when the hole is stretched. 所述附加拉伸步骤不仅使孔成为更宽的,而且也具有产生具有波纹形外观的纤维网的可能性。 The additional step of stretching the pores become not only wider, but also has the possibility of having a corrugated fiber web produced appearance. 这种开孔随后拉伸的组合必须精确地对准。 This combination is then stretched opening must be aligned precisely. 如果开孔和拉伸是以独立步骤进行的,如现有技术那样,则孔将不与拉伸环辊对准并且孔可能闭合。 If the apertures are stretched, and, as in the prior art, the holes will not be aligned independently ring roll to the stretching step and the hole may be closed. 另外,用该新工艺产生的纤维网由于拉伸而更柔软且更具悬垂性(松散的和/或薄化的纤维和/或膜)。 The fiber web produced with the new process due to stretching and more softer drape (loose and / or thinning of the fibers and / or films). 更薄的纤维网一般是所期望的,因为所述纤维网能够保持较少的流体。 Thinner webs are generally desirable, since the web can be held less fluid. 当纤维网用作吸收制品的顶片时,这一点是很重要的,因为顶片中的饱和度较小。 When the web as an absorbent article topsheet, this is very important because the smaller the saturation of the topsheet.

[0075] 在一个非限制性实施例中,开孔纤维网材料包括具有形成于其中的离散孔的纤维网。 [0075] In one non-limiting embodiment, the apertured web material comprises a fibrous web having discrete apertures formed therein to. 该纤维网具有第一表面和与第一表面相对的第二表面。 The web having a first surface and a second surface opposite the first surface. 该纤维网包括围绕多个离散孔的基本上非开孔区域或基体。 The web comprises a plurality of discrete apertures substantially surrounding the non-opening area or matrix.

[0076] 这些孔密集地堆积在相对小的区域内。 [0076] These holes densely packed in a relatively small area. 例如,在任何方向上,孔之间的中心至中心间距可小于或等于约2Ctoim,1 (torn,5謹,3謹,2謹,1謹,或0 · 5謹。面积为1平方英寸(645謹2)的区域中的孔的总数目可大于或等于4、25、100、250、500,1000,或3000。一英寸正方形区域中的孔的数目可通过如下方式来确定:用细尖笔或记号笔在材料上画出一个尺寸为1英寸(25.4mm)乘1英寸的正方形区域,并且对完全或部分地位于该1英寸正方形内或位于其边界上的第一孔,第二孔,第三孔等的数目进行计数。如果需要,可使用低倍显微镜或其它放大辅助装置来辅助材料中孔的可视性。孔可为任何合适的构型。 For example, in any direction, the center-to-center distance between the holes may be less than or equal to about 2Ctoim, 1 (torn, 5 wish, wish to 3, 2 wish, a wish, or may wish to 0 · 5. Area of one square inch ( the number of the total number of holes 645 may wish to 2) in the region of greater than or equal 4,25,100,250,500,1000, or holes in the square region 3000. one inch may be determined by: with fine tip pen or marker to draw in the material having a size of 1 inch (25.4mm) by 1 inch square area, and to completely or partially within the one-inch square or a first aperture positioned on a boundary, a second hole , the number of such third hole counts. If desired, low power microscope may be used or another auxiliary means for amplifying mesoporous materials visibility assist apertures may be of any suitable configuration.

[0077] 孔可为任何合适的尺寸。 [0077] The hole may be of any suitable size. 通常,孔将为宏观的。 Typically, the hole will be macroscopic. 孔的平面图面积可大于或等于约0.5mm 2、1mm2、5mm2、10mm2,或15mm2。 Plan area of the holes may be greater than or equal to about 0.5mm 2,1mm2,5mm2,10mm2, or 15mm2. 本文所述的方法也能够用来产生微观孔,它们具有小于0.5mm 2的平面图面积。 The methods described herein can also be used to produce microscopic pores, which have a plan area of less than 0.5mm 2.

[0078] 除了孔以外,纤维网还可包括交替的脊和凹槽,其中孔位于凹槽中。 [0078] In addition to the hole, the web may further comprise alternating ridges and grooves, wherein the holes located in the grooves. 脊可连续地延伸或在纤维网的变形的区域中形成不连续的脊。 Ridges may extend continuously or discontinuously formed in the ridge region of the deformation of the web. 凹槽可连续地延伸,其中孔在凹槽内以规则的间隙间隔开。 Grooves may extend continuously, wherein the apertures are spaced apart a regular gap within the groove. 应当注意的是,如果将纤维网颠倒过来,则凹槽将变成脊并且脊将变成凹槽,并且孔现在将位于脊中。 It should be noted that, if the web is reversed, then the grooves and ridges ridge will become will become grooves and holes in the ridge now. 取决于工艺和材料参数,孔可为二维的或三维的。 Depending on the process and material parameters, the holes may be two-dimensional or three-dimensional. 就三维孔而言,孔的基部将在脊的相反方向上延伸。 On three holes, the holes of the base portion extending in the opposite direction of the ridge. 与脊顶部和凹槽底部相比,脊侧面和凹槽侧面在更大程度上取向在Z方向上。 Compared with the tops of the ridges and bottoms of the grooves, the ridges and grooves side side alignment to a greater extent in the Z-direction.

[0079] 就膜而言,由于拉伸工艺的缘故,脊侧面和凹槽侧面与脊顶部和凹槽底部相比可较薄并具有较低的基重。 [0079] For the film, since because of the drawing process, the ridges and grooves the side of the ridge top and bottom sides of the recess may be thinner as compared with lower basis weight. 这导致纤维网具有交替的厚度和基重较高的区域以及厚度和基重较低的区域,其中厚度和基重较高的区域位于脊顶部和凹槽底部中,并且具有较低厚度和基重的区域位于它们之间的侧壁中。 This results in a web having a basis weight and thickness of alternating high regions and low weight and thickness of the base region, wherein the thickness of the high basis weight region and the ridge top and bottom of the groove and having a thickness and a lower substrate heavy region of the sidewall therebetween. 交替的基重提供有益于舒适度的薄化的/柔性区域并保持有益于强度的厚度。 Alternately providing a basis weight of thin / flexible region and maintain beneficial comfort benefit thickness strength.

[0080] 就非织造材料而言,同样在拉伸区域中减小了基重,这同样导致纤维网具有交替的基重较高和基重较低的区域,其中基重较高的区域位于脊顶部和凹槽底部中,并且基重较低的区域位于它们之间的侧壁中。 [0080] For non-woven materials, in the stretching zone is likewise reduced basis weight, which also leads to a weight of a web having alternating higher and lower basis weight of the base region, wherein the high basis weight region of the ridge top and bottom grooves and a lower basis weight region of the side walls between them. 就非织造材料而言,纤维网厚度可不在拉伸区域中减小,因为纤维可解除缠结并移动远离彼此。 In terms of nonwoven material, thickness of the web in the stretching zone may be reduced, because the fibers can be disentangled and move away from each other. 然而,所述各个纤维中的一些的厚度可由于拉伸而减小,导致纤维直径在初始纤维直径的40 %至80%范围内。 However, the thickness in some of the individual fibers may be reduced due to the stretching, resulting in fiber diameter in the range of 40-80% of the original fiber diameter. 脊顶部处的平均纤维直径和凹槽底部处的平均纤维直径可大于侧壁处的平均纤维直径。 The average fiber diameter of the average fiber diameter of the ridge at the top and bottom of the groove may be greater than the average fiber diameter at the sidewalls. 虽然齿锁定在脊和凹槽处,但基部纤维网厚度并没有显著地改变。 Although the ridges and grooves in the teeth of the lock, but the thickness of the base web is not significantly changed. 虽然纤维网是纹理化的,但局部位于脊和凹槽处的纤维网的厚度没有显著地改变,这是由于脊和凹槽未被填充,而是形成了中空区域,因为它们已变形至平面外。 While the web is textured, but the local thickness of the web at the ridge and groove is not changed significantly, due to the ridges and grooves are not filled, but the formation of a hollow region, because they are deformed to plane outer. 中空的脊不能够像填充的脊那样保持许多流体,当用作吸收制品中的顶片时其可提供干爽有益效果。 Hollow ridges can not be kept as many as a fluid-filled ridge, when used as a top sheet of the absorbent article which may provide a beneficial effect dry. 由于拉伸的缘故,纤维网在拉伸方向上永久性地伸长。 Due to the stretching of the reason, the web is permanently elongated in the stretching direction. 适宜地,拉伸区域中的纤维网厚度为初始纤维网厚度的20%至80%。 Suitably, the stretching zone web thickness is 20-80% of the original thickness of the web.

[0081] II.用于使纤维网材料变形的现有技术的设备 Equipment [0081] II. The prior art for modification of the web material

[0082] 现有技术的方法不适用于产生在横向上具有更宽尺寸的孔,尤其是对于坚韧的或抗撕裂性膜来讲。 [0082] The method of the prior art do not apply to create a hole having a wider dimension in the transverse direction, especially for tough terms or tear film. 因此,希望设计出如下工艺,其使得能够以相同的工艺步骤(即,在相同的辊隙内并且在开孔齿仍然穿透纤维网期间)进行开孔和拉伸以在纤维网材料中获得孔,所述孔与用现有技术的方法所能够获得的孔相比在横向上具有较大尺寸。 Accordingly, it is desirable to design the following process, which makes it possible to process the same steps (i.e., in the same nip and still penetrate the fibrous web during the opening of teeth) for opening and stretching the web material in order to obtain the a bore hole as compared with the prior art methods can be obtained by having a larger dimension in the transverse direction. 现有技术的方法也不适用于使用高速开孔和拉伸装置诸如此处所述的开孔和拉伸装置来产生具有交替的脊和凹槽的纤维网,其中孔位于凹槽中。 The method of the prior art are not suitable for high-speed opening and the drawing means to produce a web having alternating ridges and grooves opening and stretching means, such as described herein, wherein the aperture is located in the recess.

[0087] III.利用具有从凸脊延伸的齿对纤维网材料进行开孔的设备和方法 [0087] III. Utilization of web material having openings apparatus and method ridges extending from the tooth

[0088] -般来讲,该设备包括在两者间形成辊隙的两个相互啮合的成形结构。 [0088] - generally speaking, the apparatus comprises a shaping structure forming two intermeshing nip therebetween. 成形结构可包括辊,板,带,套管,能够向纤维网赋予纹理向的其它结构、或它们的组合。 Shaped structure may include a roll, plate, belt, sleeve, other configurations capable of imparting texture to the web, or a combination thereof. 第一成形结构包括成形结构的表面上的多个第一脊和第一凹槽,其中所述第一脊具有顶部表面,并且所述第一凹槽具有底部表面。 First forming structure comprises a plurality of ridges on a first surface of the first groove forming structure, wherein the first ridge having a top surface, and said first groove having a bottom surface. 第一成形结构还包括从所述第一脊的顶部表面向外延伸的间隔开的多个齿,每个齿均能够形成孔,其中所述第一脊的顶部表面位于所述齿的末端和所述第一凹槽的底部表面之间。 The first structure further comprises forming a plurality of teeth spaced apart from the top surface of the first outwardly extending ridge, each tooth hole can be formed, wherein the top surface of the first ridge located at the ends of the teeth and between the bottom surface of the first groove. 第二成形结构包括多个连续的第二脊和第二凹槽。 The second forming structure comprises a plurality of ridges and a second continuous second groove.

[0089] 更具体地,该设备包括在两者间形成单一辊隙N的单一一对反转的相互啮合辊。 [0089] More specifically, the apparatus comprises a single nip N forming a single pair of engagement with each other between the two reversing rolls. 虽然为方便起见,本文将主要以辊来描述这些设备,但应当理解,本描述将适用于可包括任何合适类型的成形构件的任何合适的设备,所述成形构件包括但不限于:一对辊;多对板;具有弹力盘(或小板)的传送装置;带;或它们的组合。 Although for convenience, mainly to the roller will herein to describe these devices, it is to be understood that the description would apply to any suitable device may comprise any suitable type of molding member, the molding member include, but are not limited to: a pair of rollers ; plurality of plates; transfer means having a puck (or small plates); a belt; or a combination thereof. 第一辊和第二辊各自包括表面106、108, 所述表面包括周向延伸的多个脊和凹槽。 The first and second rollers 106, 108 each include a surface, said surface comprising a plurality of circumferentially extending ridges and grooves. 作为另外一种选择,脊和凹槽可在平行于辊轴线的方向上延伸,只要其与具有在相同方向上延伸的脊和凹槽配对的辊即可。 Alternatively, the ridges and grooves may extend in a direction parallel to the roller axis, as long as it can be paired with the roller having ridges and grooves extending in the same direction. 第一辊另外还包括间隔开的多个齿,其中齿从脊的顶部表面向外延伸。 First roller additionally comprises a plurality of spaced apart teeth, wherein the teeth extend outwardly from the top surface of the ridge. 这产生"凸脊"。 This creates a "ridge." 第二辊的脊朝第一辊的轴线延伸至超过第一辊上的脊中的至少一些的顶部的深度。 Depth of at least some of the ridges towards the top of the second roller to the axis of the first roll extends over a ridge on the first roller. 这样,齿的初始接合产生孔,随后当所述接合进行至凸脊以下的深度时,所述孔在横向上被拉伸。 Thus, the initial engagement of the teeth generating aperture, when the engagement subsequently performed to a depth below the ridge, the aperture is stretched in the transverse direction. 通过在一个工艺步骤中首先进行开孔随后在齿仍然穿透纤维网期间进行拉伸,所得的孔与由如上所述且如图2A- 2D所示的标准齿辊所产生的孔相比在横向上具有较大的宽度。 By opening a first process step in a subsequent web remains stretched during penetration of the teeth, compared to a reference tooth rollers hole described above and shown in FIGS. 2A- 2D produced in the resulting hole having a transverse width greater.

[0090] 本发明的孔与现有技术的孔相比包括较低的纵横比(孔长度:孔宽度)和高得多的开口面积,尤其是当用于较坚韧的膜时,例如,包含高含量的LLDPE的那些。 [0090] bore holes prior art compared to the present invention comprises a lower aspect ratio: the opening area (aperture length pore width) and much higher, especially when used for tougher membranes, e.g., comprising LLDPE those high levels. 新齿几何形状有利于在较低的模具温度下获得高开口面积,使得能够在纤维网中形成孔,所述纤维网不能够被开孔为具有传统齿几何形状。 The new tooth geometry favorable for obtaining a high open area at a lower mold temperature, so that the holes can be formed in the web, the web can not be open to having a conventional tooth geometry. 新模具几何形状提供在较低的温度下(例如,介于35和70 摄氏度之间)或甚至在环境温度下对纤维网开孔的能力,而不需要对设备进行加热。 New mold geometry provided at a low temperature (e.g., between 35 and 70 degrees C) or even to the ability of the fibers CAPE hole without the need for heating the device at ambient temperature. 另外, 相对于以前的模具,所涉及的用以产生该模具的成本极少或较低,因为尤其是被移除的金属较少。 Further, with respect to previous molds, the mold cost for generating involved little or lower, in particular because less metal to be removed. 因此,可使用室温前体纤维网。 Thus, using RT precursor web. 在一个实施例中,前体纤维网和相互啮合辊不受热。 In one embodiment, the precursor web and the rollers intermesh without heat. 或可使用总体预热的纤维网。 Or can be used in general preheated web. 或分区预热纤维网可使得能够在一些区中形成孔并且在其它区中形成气泡。 Preheating or partition webs can be formed such that holes may be in some region other and form bubbles in the zone. 预热可通过如下方法实现:在接合之前包裹滚刀开孔辊(其中在接合之前可能使用变化的包裹时间)或在接合之前包裹环辊。 Preheating may be achieved by the following method: prior to engagement RKA roll wrapping (which may be used prior to engagement of wrapping time) or wrapped prior to engagement ring roll. 同样,可使用受热的或非受热的模具。 Likewise, the use of a heated or non-heated molds. 适宜地,通过包裹被加热至50-200摄氏度,或50-100摄氏度的滚刀开孔辊来加热纤维网。 Suitably, heated to 50-200 ° C by wrapping, or open rolls hob 50-100 ° C to heat the web. 滚刀开孔辊和环辊可按相同的最外表面的速度被驱动,或在所述两个辊之间可存在速度差。 RKA roll and ring roll may be the same outermost surface speed of the drive, or there may be a difference in speed between the two rollers.

[0098] 凸脊滚刀开孔辊102的构型使得脊120的顶部表面122设置在齿130的末端134和凹槽110的底部表面112之间,依相对于辊102的轴线A的方向而定。 [0098] raised ridge RKA roll configuration 102 such that the top surface of the ridge 120 is disposed between the bottom surface 122 ends 134 and 110 of the recess 112 of the teeth 130, depending on the direction of the axis A with respect to the roller 102 and set. 齿高ht被定义为齿130的末端134和凹槽110的底部表面112之间的距离。 Ht tooth height is defined as the distance between the bottom surface 112 of the tip 134 and the recess 110 of the teeth 130. 齿高ht为1mm至12mm,或2mm至8mm,或3mm至6mm。 Tooth height ht of 1mm to 12mm, or 2mm to 8mm, or 3mm to 6mm. 脊高hr为齿高的至少20%,通常为20%至95%。 Hr ridge height is at least 20% higher teeth, typically 20% to 95%. 横切深度d。 Cross-cut depth d. . 被定义为齿130的末端134 和脊120的顶部表面122之间的距离。 It is defined as the tooth top ends 134 and 130 of the distance between the surface of the ridge 120 122. 在该实施例中,齿130的末端134和脊120的顶部表面122之间的距离围绕该辊的圆周为基本上相同的。 In this embodiment, the distance between the ends 134 of the teeth 130 and the top surface of the ridge 120 around the circumference of the roll 122 is substantially the same. 横切深度d cc取决于形成所述孔所需的变形量。 Depth d cc transverse deformation amount required depends on the formation of the hole. 例如,横切深度dcc可在0 · 2謹至9謹,或1 · (torn至4 · Ctoim或2 · Ctoim至3 · 5謹范围内。较小的横切深度dcc (在相同的D0E下)产生更大开口的孔。一对辊102,104的啮合深度必须大于横切深度dcc。适宜地,啮合深度比横切深度大至少0 · 1mm或大0 · 3mm。辊隙N处的D0E为0 · 5mm至10mm,或3mm 至7mm,或3mm 至4mm 〇 For example, cross-cut depth can range from 0 · 2 dcc wish wish to 9, or 1 · (torn to 4 · Ctoim or 2 · Ctoim wish to 3.5 within the range. Dcc smaller cross-cut depth (at the same D0E ) generates a larger opening of the hole depth of engagement a pair of rollers 102, 104 must be greater than the depth of transverse DCC. suitably, the depth of engagement than the cross-cut depth is at least 0 · 1mm or large 0 · 3mm. the roll nip N is 0 D0E · 5mm to 10mm, or 3mm to 7mm, or 3mm to 4mm square

[0099] 脊高hr被定义为脊120的顶部表面122和凹槽110的底部表面112之间的距离。 [0099] hr ridge height is defined as the top surface of the ridge 120 and the distance between the bottom surface of the groove 122 110 112. 在一些诸如图3B和4A所示的实施例中,第一辊102包括横向宽度,并且脊120的顶部表面122和凹槽110的底部表面112之间的距离围绕所述圆周以及横跨辊102的横向宽度为基本上相同的。 In some embodiments, such as illustrated in FIG. 3B and 4A, the first roll 102 includes a transverse width, a distance between the ridge and the top surface 120 and bottom surface 122 of recess 110 and 112 around the circumference of the roller 102 across the transverse width substantially the same. 或第一脊的顶部表面和第二凹槽的底部表面之间的距离围绕所述圆周或横跨第一辊的横向宽度可有变化。 Distance between the top surface or bottom surface of the first ridge and the second recess around the circumference or across the transverse width of the first roll may vary. 凸脊辊的各种可供选择的实施例是可能的。 Various alternative embodiments of roller ridges are possible. 例如,如图8中的辊162所示,脊的高度hr在齿168中的至少一些之间可有变化。 For example, as shown in FIG. 8, the ridges 162 of roll height hr can vary between at least some of the teeth 168. 脊高hr取决于形成所期望的孔所需的变形量。 Ridge height hr depending on the amount of deformation required to form the desired holes. 位于一对齿168之间的至少一个脊164的顶部表面166将具有如下高度h rl,所述高度按至少10%,20%,或30%大于位于另一对齿168之间的另一个脊164的高度hr2。 The other is located at a different pair of ridges 168 between the teeth 168 between the at least one top surface 166 of the ridge 164 has a height h rl, according to the height of at least 10%, 20%, or 30% greater than the tooth is located hr2 164 of height. 该辊162可用于某种工艺诸如图3A所示的工艺以取代凸脊滚刀开孔辊102。 The roller 162 may be used for some process such as the process shown in FIG. 3A substituted raised ridge RKA roller 102. 第二辊可为环辊,其具有在周向或轴向上具有不同高度的脊。 The second roll may be a ring roller having ridges having different heights in the circumferential direction or the axial direction.

[0100]图9A示出了可通过图3A所示的设备来制备的纤维网170的一个例子:具有交错的齿图案的滚刀开孔凸脊辊用作上辊102并且环辊用作下辊104。 [0100] FIG 9A shows an example of the web through the apparatus 170 illustrated in FIG prepared 3A: having staggered pattern RKA toothed ridges 102 on the roller as the roller and the ring roller is used as the roller 104. 辊102和104在横向上对齐, 使得第一辊102上的齿130与第二辊104上的凹槽140对齐。 Rolls 102 and 104 are aligned in the transverse direction, so that the teeth 130 on the second grooves 104 on the first roller 102 and the roller 140 is aligned. 当第一辊102上的齿130穿透纤维网170时,位于滚刀开孔凸脊辊102上的齿130之间的脊120支撑纤维网170,使得第二辊104 上的脊150可在横向上拉伸纤维网170。 When the teeth 130 penetrate the fiber web 102 on the first roll 170, located between the ridges 130 on the roll 102 RKA toothed ridges 120 supporting the fiber web 170, such that the ridges on the second roller may 104,150 transversely stretched web 170.

[0101] 处于其初始状态的纤维网可被认为是相对平坦的,并且完全由非开孔区域构成。 [0101] in its initial state of the web can be considered to be relatively flat and comprised entirely of non-opening area. 纤维网170具有第一表面170A和第二表面170B。 Web 170 has a first surface 170A and second surface 170B. 当纤维网在纵向上被喂送到位于辊(例如, 图3A所示的那些)之间的辊隙N中时,纤维网:(i)由第一辊102的齿130开孔以形成间隔开的多个孔172;并且(ii)由第一辊102的脊120拉伸以在横向上拉伸孔172。 When the fiber web in the longitudinal direction is fed into the roller nip between the N (e.g., those shown in FIG. 3A), the web: (i) a first aperture teeth 130 of roll 102 to form a spacer apart plurality of apertures 172; and (ii) a first roller 102 by ridges 120 stretched in the transverse direction to stretch the hole 172. 如图9A即纤维网顶视图所示,结果得到包括孔172和围绕孔172的基体174的开孔纤维网170。 I.e., FIG. 9A shown a top view of the web, and the results obtained including the base body surrounding the hole 172 hole 172 opening 170 of the web 174. 孔172可在一个方向上(朝下,如在图9A中观察到的那样)被推出纤维网160的平面之外,因此孔172可具有高度&。 Hole 172 may be in one direction (downwards, as viewed in FIG. 9A above) is pushed out of the plane of the web 160, so the hole 172 may have a height &. 孔172在纵向和横向上成行对齐。 Hole 172 are aligned in rows in the longitudinal and transverse directions. 图9B示出了单一孔172的放大顶视图。 FIG 9B shows an enlarged top view of a single aperture 172. 孔172包括纵向上的长度L a和横向上的宽度1。 L a hole 172 and a width 1 comprising on on the lateral longitudinal length. 孔将优选地具有长度除以宽度的1至4,或1.25至3,或1.5 至2.5,或1.6至2.3的纵横比AR。 The holes preferably have from 1 to 4, or 1.25 to 3, or 1.5 to 2.5, aspect ratio, or length divided by the width ratio of 1.6 to 2.3 AR. 孔172还包括各个开口面积A a和围绕开口面积?3的周边。 Further comprising a hole 172 A a respective opening area and the opening area of around? 3 Zhou Bian. 开孔纤维网所包括的总开口面积为总纤维网面积的5%至25%,或9%至21 %,或10%至16%, 或14 %至20 %。 The total open area of the apertured web comprises of from 5 to 25% of the total area of the web, or 9-21%, or 10-16%, or 14-20%. 开孔膜包括在1.5N至5N,2N至4N,2.5N至4N,2.5N至3.5N,或2.7N至3.9N范围内的横向上的撕裂或拉伸强度(每25.4mm)。 Apertured film comprising 1.5N to 5N, 2N to 4N, 2.5N to 4N, 2.5N to 3.5N, or 2.7N to 3.9N tear or tensile strength in the transverse direction in the range (per 25.4mm). 开孔非织造材料包括2N至20N范围内,或更高的横向上的拉伸强度(每25.4mm)。 Apertured nonwovens are included within the scope 2N to 20N, or a tensile strength (per 25.4mm) in the lateral direction higher. 在一个例子中,纤维网包括纵向取向和横向取向,其中孔包括纵向上的长度和横向上的宽度,并且其中多个孔包括长度除以宽度的1至4的纵横比。 In one example, the web comprising longitudinally oriented and a landscape orientation, wherein the aperture comprises the length and width of the lateral upper longitudinal, and wherein the plurality of apertures comprises an aspect ratio of length divided by the width of 1 to 4.

[0102] 在一些实施例中,上述拉伸步骤不仅增加了孔的横向宽度,而且也产生了交替的脊和凹槽,其中孔位于凹槽中。 [0102] In some embodiments, the above-described stretching step not only increases the lateral width of the hole, but also produces alternating ridges and grooves, wherein the holes located in the grooves. 与所述两个辊上的脊接触的纤维网的部分摩擦锁定在脊顶部上因而不被拉伸,而介于脊之间的纤维网被拉伸出平面之外。 Of friction to the web in contact with the two ridges on the locking rollers on top of the ridge is therefore not stretched, and the web is pulled interposed between the ridges protrude out of the plane. 被拉伸出平面之外的纤维网的部分变得在更大程度上取向在z方向上。 Protruding portion is pulled out of the plane of the web become oriented in the z-direction to a greater extent. 因此,可形成具有脊和凹槽的纤维网,其中孔位于凹槽中。 Thus, the web may be formed with ridges and grooves, wherein the holes located in the grooves. 应当注意的是,如果将纤维网颠倒过来,则凹槽将变成脊并且脊将变成凹槽, 并且孔现在将位于脊中。 It should be noted that, if the web is reversed, then the grooves and ridges ridge will become will become grooves and holes in the ridge now. 脊顶部处的纤维和凹槽底部处的纤维与侧壁处的纤维相比可在更大程度上取向在XY平面中。 Fibers of the fiber at the groove bottom and at the top of the ridges as compared to the fibers at the sidewall in the XY plane may be oriented to a greater degree.

[0103] 就膜而言,在拉伸区域中纤维网被薄化并且基重减小,而在摩擦锁定在辊脊上的纤维网的区域中纤维网厚度和基重保持不变。 [0103] For the film, the web is thinned and the basis weight is reduced in the stretching zone, and the roller a friction locking ridge in the region of the web thickness of the web and the basis weight remains unchanged. 这导致纤维网具有交替的厚度较高和厚度较低的区域、以及交替的基重较高和基重较低的区域,其中厚度较高和基重较高的区域位于脊顶部和凹槽底部中,并且具有较低厚度和较低基重的区域位于它们之间的侧壁中。 This results in a web having alternating higher and lower thickness region of thickness, and weight of alternating high and low basis weight regions group, with higher thickness and higher basis weight region of the top of the ridge and the groove bottom , and having a lower basis weight and thickness of the lower region of the side wall between them. 图11 为25gsm PE膜纤维网210的顶视图(膜被拉伸/被展平以示出高基重区域212和低基重区域214)。 FIG 11 is a top view (stretched film is / are flattened to show a high basis weight regions and low basis weight regions 212 214) 25gsm PE film web 210. 纤维网210还示出了脊R,凹槽G,和侧壁S。 Fibrous web 210 also shows that the ridges R, grooves G, and the sidewall S. 孔216存在于凹槽G中。 Hole 216 present in the groove G. 显而易见,高基重区域212位于脊R和凹槽G中,而低基重区域214位于侧壁S中。 Obviously, the high basis weight region 212 is located in the groove G and the land R, the low basis weight region 214 is located in the sidewall S.

[0104] 就非织造材料而言,同样在拉伸区域中减小了基重,这同样导致纤维网具有交替的较高基重和较低基重的区域,其中较高基重区域位于脊顶部和凹槽底部中,并且较低基重区域位于它们之间的侧壁中。 [0104] For non-woven materials, also in the stretching zone basis weight is reduced, which also results in a web having a higher basis weight regions and low basis weight alternately, wherein the high basis weight region of the ridge top and bottom of the groove and the side wall lower basis weight region between them. 图12为60gsm聚丙烯非织造纤维网220的顶视图(非织造材料被拉伸/被展平以示出高基重区域222和低基重区域224)。 FIG 12 is a top view (stretched nonwoven is / are flattened to show a high basis weight regions and low basis weight regions 222 224) 60gsm polypropylene nonwoven web 220. 纤维网220还示出了脊R,凹槽G,和侧壁S。 Web 220 also shows that the ridges R, grooves G, and the sidewall S. 孔226存在于凹槽G中。 Hole 226 present in the groove G. 热粘合点或熔合粘合点228可存在于纤维网220上的各种位置中。 Thermal point bonding or fusion bonding points 228 may be present in various locations on the web 220. 显而易见,高基重区域222位于脊R和凹槽G中,而低基重区域224位于侧壁S中。 Obviously, the high basis weight region 222 is located in the groove G and the land R, the low basis weight region 224 is located in the sidewall S. 就非织造材料而言,纤维网厚度在拉伸区域中可不减小,因为纤维可解除缠结并移动远离彼此。 In terms of nonwoven material, thickness of the web in the stretching zone may be reduced, because the fibers can be disentangled and move away from each other. 然而,所述各个纤维中的一些的厚度可由于拉伸而减小。 However, the thickness in some of the individual fibers may be reduced due to the stretching. 应当注意的是,用来表征基重的纤维网的"区域"不包括孔自身。 It should be noted that the basis weight used to characterize the web "region" does not include the hole itself.

[0105] 由于拉伸的缘故,纤维网在拉伸方向上永久性地伸长。 [0105] Due to the stretching of the reason, the web is permanently elongated in the stretching direction. 如果纤维网保持在其波纹形状态,则所增加的纤维网宽度的大部分被形成于纤维网中的脊和凹槽填充。 If the web remains in its corrugated state, the increased width of the web fibers are formed in most of the fiber web filled with ridges and grooves. 作为另外一种选择,可施加张力以伸展纤维网,这将导致脊和凹槽的高度和频率减小,并且减小纤维网的总体基重。 Alternatively, Zhang Li may be applied to stretch the web, which will result in the ridges and grooves of reduced height and frequency, and reduce the overall weight of the base web. 如果需要,可伸展纤维网使得脊和凹槽不再存在,并且纤维网回复至其展平状态。 If desired, the web can be stretched so that the ridges and grooves are no longer present, and the web to return to its flat state. 该变形工艺可在横向上拉伸纤维网或使纤维网生长10%,15%,20%,25%,或更多。 The deformation process can be stretched in the transverse web or webs grown 10%, 15%, 20%, 25%, or more. 脊和凹槽的永久拉伸量和成型度取决于模具几何形状,工艺条件和材料的特性。 The amount of permanent elongation and forming ridges and grooves of the mold depending on the characteristics of the geometry, material and process conditions. 通常,与膜材料相比,该工艺将永久性地拉伸非织造纤维网材料或使非织造纤维网材料生长得更多。 Typically, compared with the film material, the process will be permanently stretched nonwoven web material or a nonwoven web material grows more. 例如,纤维网可在横向上从165mm生长至190_。 For example, the web may be grown to 165mm in the lateral direction from 190_. 适宜地,该纤维网具有初始纤维网基重区域和较低基重区域,所述较低基重区域具有低于初始纤维网基重的基重。 Suitably, the web having an initial basis weight of the web area and a lower basis weight region, the region has a lower basis weight lower than the initial basis weight of the web basis weight.
