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

技术领域 Technical 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 the opening of the web material and means for opening and stretching fiber web to form a device and method for 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 disclosed for the web is perforated, deformed and / or stretching of the various methods and equipment. 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 the opening of the hob opening, it is difficult to produce closely spaced holes having a web, wherein the apertures have a desired width in the transverse direction ("CD") on. 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。 In order to line the hole spacing into closer together, we can provide a very small angle activation teeth. 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, because the resulting hole in the transverse width does not have enough holes, even at high depth of engagement (activation Roll paired ring roller interference) under as 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, low opening 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 relatively tough and tear resistance of more webs, slit-like, resulting in lower opening hole area in particular is a 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 hot needle hole is a common approach, but it has the drawback of requiring the counter roll has a greater alignment accuracy, and it usually results in a larger 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 hot needle openings generally lower line speed.

[0003] 有可能对开孔纤维网进行柱式环轧制以拉伸它,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] The apertured web may be pillar for ring rolling to stretch it, but may result in alternating rows of aperture size, because the holes are not capable of ring roll stretching process subsequent registration. 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。 Since the variable spreading substrate, it is difficult structurally laterally aligned with the subsequent process. 柱式环轧制也可能显著地弱化纤维网,从而使得其更易于撕裂。 Column ring rolling also 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] desirable to produce a kind of discrete, closely spaced apertures web, wherein the apertures may be compared with the previous hole having 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 secure and thus laterally in the transverse direction is not easy to tear holes 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。 A need for a method of generating the following apertured web, said web having a larger aperture, a wider, larger diameter opening. 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 allow the web to be opening forming apparatus having an aperture, said aperture 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,例如环轧制。 [0005] There are many known processes for producing the ridges and grooves with webs, such as ring rolling. 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 web having apertures, e.g., apertures hot needle. 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 corrugated web having a pattern of holes aligned with a particular alternating ridges and grooves. 存在用于进行微开孔然后进行环轧制的工艺。 Exist for micro hole and then ring rolling process. 然而,这导致不具有波纹的平坦的纤维网。 However, this does not lead to the flat web having a corrugation. 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)。 Via the patterned belt or water jet to form a ridge and groove web (flat bars). 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, jet or water is a much slower process and requires 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 ridges are 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 alternating ridges and grooves having a fiber web, wherein the web holes located in a specific location, e.g., located in the recess or in the ridges. 需要一种包括对准的波纹图案的开孔纤维网。 Including the need for an undulating pattern of openings aligned fibers.

[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 objectives of the present invention; embodiments described herein may be implemented in various combinations of these goals. 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, implement 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 the opening of the web material and means for opening and stretching the fiber network for devices and methods to produce such materials, the apparatus and method overcomes the disadvantages of the prior art, one or more persons. 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 enables the web by reducing the basis weight and overall cost reduction. 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 performing the opening and stretched in the same process step, generating in the 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, opening and stretching are aligned in a single unit in the manner such that the teeth are still drawn during the infiltration material, and therefore not allowed to occur when the hole is stretched collapsed. 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 hole not only becomes wider but also has the possibility to produce webs having a corrugated appearance. 这种开孔随后拉伸的组合必须精确地对准。 This combination is then drawn openings must be precisely aligned. 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 opening and stretching steps are carried out independently, as in the prior art, the hole will not be aligned with the stretch ring rolls and holes can be closed. 另夕卜,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)。 Another evening BU, with this new process produces web due softer and more stretching drape (loose and / or thinning of the fibers and / or film). 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。 It is generally thinner web is desirable, because the web can be maintained with 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, and 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, it comprises a web material having openings formed therein discrete apertures web. 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 surround 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 are densely deposited 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20mm, 10mm,5mm,3mm,2mm,Imm,或0. 5_。 For example, in any direction, between the center-to-center hole spacing can be less than or equal to about 20mm, 10mm, 5mm, 3mm, 2mm, Imm, or 0. 5_. 面积为1平方英寸(645mm2) 的区域中的孔的总数目可大于或等于4、25、100、250、500, 1000,或3000。 The total number of holes area of one square inch (645mm2) region may be greater than or equal to 4,25,100,250,500, 1000, or 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。 Number of holes one inch square area may be determined by the following way: with a fine-tip pen or marker to draw on the material in a size of 1 inch (25.4mm) by 1 inch square area, and to totally or partially located within the 1 inch square hole in the first or the boundary thereof, the number of the second hole, third hole and other counts. 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。 If necessary, use a low-power microscope or other assistive devices to aid visibility enlarge the hole in the material. 孔可为任何合适的构型。 Holes can be any suitable configuration.

[0077] 孔可为任何合适的尺寸。 [0077] 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. 5mm2、lmm2、5mm2、10mm2,或15mm 2。 Plan area of the holes may be greater than or equal to about 0. 5mm2, lmm2,5mm2,10mm2, or 15mm 2. 本文所述的方法也能够用来产生微观孔,它们具有小于0. 5mm2的平面图面积。 The methods described herein can be used to produce microscopic holes, which have an area of less than 0. 5mm2 plan view.

[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 holes, the web may further comprise alternating ridges and grooves, wherein the aperture is located in the recess. 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。 The spine may extend continuously or discontinuously formed in the ridge region of the web of the deformation. 凹槽可连续地延伸,其中孔在凹槽内以规则的间隙间隔开。 Groove may extend continuously, wherein the hole in the recess with a gap open at regular intervals. 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 upside down, the grooves and ridges will be turned into the groove land, and the hole is now located ridges. 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 hole can 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 base of the hole extending ridge in the opposite direction. 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 top and bottom of the ridge grooves, ridges and grooves side side to a greater extent oriented 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] on film, since because of the drawing process, the ridge sides and the top side and bottom of the groove and the land-groove can be thin 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 leads to webs having a basis weight and thickness of alternating high regions and low basis weight and thickness of the region, and wherein the thickness of the high basis weight region located at the top and bottom of the ridge grooves, and having a thickness and a lower substrate heavy region is located in 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。 The basis weight alternately provide useful comfort thinning / flex area and thickness of the holding benefit 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] The nonwoven material, the same decrease in the stretching area basis weight, which also leads to a web having a basis weight of higher and lower basis weight regions alternately, wherein the basis weight of the high region is located The top and bottom of the ridge grooves, and the basis weight of the lower area of the side wall 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。 The nonwoven materials, web thickness may be reduced in the stretching zone, 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 of the individual fibers some of which may be reduced due to the stretching, resulting in fiber diameter within the range of 40 to 80% of the initial 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 at the top of the ridge and groove bottom may be greater than the average fiber diameter at the sidewall. 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 teeth locked in land and groove at the base of the web thickness but did not significantly change. 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 thickness of the fiber web partially located at the ridges and grooves do not significantly change, which is due to the ridges and grooves are not filled, but the formation of a hollow region, because they are deformed to plane outside. 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 ridge ridges can not be filled as many as fluid retention, when used as a topsheet in absorbent articles that 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。 Since stretching sake web in the stretching direction is permanently elongated. 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 tensile region web thickness of 20 to 80% of the initial thickness of the web.

[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 transverse width of the hole, but also had alternating ridges and grooves, wherein the aperture is located in the recess. 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。 Portion in frictional contact with the ridge on the two web rolls on top of the ridge lock therefore not be 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。 The protruding portion of the web is pulled out of the plane becomes a greater extent oriented in the z direction. 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 formation of ridges and grooves with webs, wherein the hole is located in the recess. 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 upside down, the grooves and ridges will be turned into the groove land, and the hole is now located ridges. 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。 Fiber fiber and the groove at the bottom of the ridge at the top of the side walls of the fiber can be compared to a greater extent oriented in the XY plane.

[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 films, the web in the stretching region is thinned and the basis weight is reduced, and the friction roller locking ridge in the region of the web thickness and basis weight of the web remain 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 leads to a higher fiber web having alternating thickness and the thickness of the lower region, and the basis weight of the high and low basis weight regions alternating, wherein the high thickness and high basis weight regions located at the top and bottom of the groove ridges , and has a low thickness and low basis weight region is located in the side walls therebetween. 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)。 25gsm PE 11 is a top view of the film web 210 (the film is stretched / flattened to show the high basis weight region 212 and a low basis weight region 214). 纤维网210还示出了脊R,凹槽G,和侧壁S。 Web 210 also shows a ridge R, groove G, and the sidewall S. 孔216存在于凹槽G中。 Hole 216 present in the groove G in. 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] The nonwoven material, also in the stretch zone is reduced basis weight, which also leads to a web having a basis weight regions of alternating high and low basis weight, the basis weight of the region in which the high ridge located The top and bottom of the groove, and a lower basis weight region is located in the side walls therebetween. 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)。 12 is a 60gsm polypropylene nonwoven web 220, a top view (a nonwoven material is stretched / flattened to show a high basis weight region 222 and the low basis weight region 224). 纤维网220还示出了脊R,凹槽G,和侧壁S。 Web 220 also shows the ridge R, the grooves G, and sidewalls S. 孔226存在于凹槽G中。 Hole 226 present in the groove G in. 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 bonding or fusion bonding points 228 points can exist 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。 The nonwoven materials, web thickness may be reduced in the stretching zone, 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 of the individual fibers may be due to some of the stretching increases. 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 of the fibers 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] Since the stretch of the reason, the web in the stretching direction is permanently extended. 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 is maintained in its corrugated state, the increase in the width of the web being formed in the web Most of the ridges and grooves filled. 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, the tension may be applied to stretch the web, which will result in the height and frequency of the ridges and grooves is reduced, 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 needed, you can stretch the web so that the ridges and grooves no longer exists, and the web to return to its flattened 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 fiber web or the fiber web growth 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。 Permanent amount of stretch and forming ridges and grooves characteristic depends on the geometry of the mold, the process conditions and materials. 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165_生长至190_。 For example, the web can be grown in the transverse direction from 165_ to 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 fiber web having a basis weight of the initial web basis weight region and a lower region, said low basis weight region having a basis weight lower than the initial web basis weight.
