Abstract
To provide the subject sheet improved in skin touch with reduced wet feel due to body fluid while retaining its performance and touch feel and capable of preventing the body fluid from oozing from the absorptive article via the open holes onto the outer surface thereof. The objective surface sheet consists of a nonwoven fabric sheet formed by fusing thermoplastic synthetic fibers. On the surface of this sheet, many ridges and flutes are alternately arranged so as not to represent a plane, the ridges are projectedly curved, while the flutes recessedly curved. Each of the flutes has an open hole with a rib extending from the surface of the sheet to the back surface , and the rib is harder than the other parts.
Description
The present invention relates to a kind of surperficial cover of absorbent commodity, in more detail, it is the most surperficial cover that directly contacts with human skin in the sanitary towel that uses of physiology or the diaper, be the performance and the feel that can keep it, can make again body fluid such as absorbed blood or urine not from this is wearing to the surperficial cover of the effusive absorbent commodity in outside.
In the past, generally all be the surperficial cover that foraminous thin film or non-woven fabrics is used as absorbent commodities such as sanitary towel that physiology uses, diaper.
Apertured film as the occasion of surperficial cover just like the special public clear 57-17081 communique of Japan Patent with the clear 60-68928 communique of Te Kai is disclosed, adopt the method for offering the hole on the surface of plastic sheeting, making body fluid absorptions such as blood or urine by this hole.
But feeling that foraminous plastic sheeting contacts with skin is relatively poor, and can make user have impression snarled like sticky feeling.
On the other hand, be well known that now non-woven fabrics made surperficial cover that in order to reduce the body fluid moist feeling to the user skin, improve the permeability of body fluid, arow is offered the hole on the non-woven fabrics of hydrophobicity.The surperficial cover of this non-woven fabrics type, except the perforate part, all the other all are planar structures, considerable surface portion contacts with skin.Therefore, wish further to alleviate and the contacting of skin, the aeration between skin and the surperficial cover is further improved.
And, hardness at the rib that surrounds the hole peripheral setting is not under the abundant strong situation, when on surperficial cover, adding the human pressure, perhaps when having absorbed the body fluid absorption volume expansion, rib is just damaged by pressure, thereby the gap between surperficial cover and the absorber is dwindled, and body fluid is seeped into the outside of surperficial cover through the hole on the surperficial cover from absorber, makes it just can not give full play to function in the early stage.
The purpose of this invention is to provide a kind of performance and feel that can keep it, the moist feeling that is formed by body fluid is reduced, contact better with skin, and can prevent that the body fluid body from oozing to the surperficial cover of the absorbent commodity of surperficial cover outside from absorber through the hole on the surperficial cover.
The objective of the invention is by providing a kind of surperficial cover with absorbent commodity of following characteristics to reach, promptly is that the nonwoven fabric sheet that forms by the thermoplastic synthetic fiber is fused constitutes; On above-mentioned nonwoven fabric sheet, make it not have planar section ground alternately to arrange and setting many row's crest parts and trough part; Above-mentioned crest partly bends to convex, and above-mentioned trough partly bends to concavity; Above-mentioned trough partly has perforate, and these perforates all have the rib that extends to the inside from the surface of above-mentioned nonwoven fabric sheet; And above-mentioned rib is made into harder than the part beyond the rib.
Because surperficial cover of the present invention is to be made of non-woven fabrics, thereby when the surperficial cover of the side that contacts with skin used as absorbent commodity, can obtain the sensation of touching skin as cloth, simultaneously again because on this nonwoven fabric sheet surface, make it not have planar section ground alternately to arrange and setting many row's crest parts and trough part, thereby just reduce significantly with the contact area of skin, surperficial cover just can be slighter with close contact of skin, and the body fluid moist feeling is also just alleviated.
Again owing to make the surface from nonwoven fabric sheet of trough part harder to the rib of the inside extension than the part beyond the rib, thereby, be subjected to the human pressure even absorbed the body fluid absorption body, after perhaps having absorbed the body fluid absorption volume expansion, absorber is crimped on the surperficial cover, because these ribs still can keep the distance between absorber and surperficial cover bigger, thereby the effect that makes the body fluid that is absorbed bulk absorption can not turn back to the face cap background of cloth is arranged.
The surperficial cover of absorbent commodity of the present invention can keep its performance and feel, can reduce the moist feeling that is formed by body fluid again, and is better with contacting of skin, can prevent that body fluid from oozing outside to surperficial cover through perforate from absorber.

As shown in Figure 1, the surperficial cover 2 of the absorbent commodity of present embodiment is to be used in the sanitary towel 1 that uses as the physiology of absorbent commodity.As shown in Figures 2 and 3, the surface non-woven thin-film 2 that forms by the thermoplastic synthetic fiber is fused of cover 2 constitutes, on the surperficial 2A of this surface cover 2, make it not have planar section ground alternately to arrange to set the crest parts 12,12 of arranging more ... with trough part 13,13 ...12 one-tenth convex ground of crest part are crooked, 13 one-tenth concavity ground of trough part are crooked.Trough part 13 has from the surface of nonwoven fabric sheet with ribbing 14 the perforate 15 of extending to the inside; This rib 14 is made into harder than part beyond the rib 14.
Below, further specify the surperficial cover 2 of the absorbent commodity of present embodiment, as shown in Figure 1, the sanitary towel 1 that physiology is used by surperficial cover 2, have impermeability leakproofing material 3, have the intermediate layer 4 of resiliency and absorber 5 to constitute.Absorber 5 except with the contacted side of skin, all the other are all covered by leakproofing material 3, absorber 5 is covered with by surperficial cover 2 by intermediate layer 4 with the contacted side of skin.Surface cover 2 also is wrapped in whole absorber 5, in the surperficial cover 2 intermediate layer 4 be clipped in the middle that part of be the body fluid absorbing part branch of the sanitary towel 1 that uses of physiology, contacted of formation and skin.
The surface cover 2 by contact with skin preferably nonwoven fabric sheet constitute, this nonwoven fabric sheet forms by fusing the thermoplastic synthetic fiber.The method that fuses has no particular limits, and for example available knurling rolls and hot blast fuse fiber.Nonwoven fabric sheet is that for example polyethylene terephthalate, polyethylene, polypropylene etc. fuse and form those known thermoplastic synthetic fibers.These thermoplastic synthetic fibers can be the composite fibres of core-cover type or parallel type.Also can use one or more thermoplastic synthetic fibers with mixing.Thermoplastic synthetic fiber's fibre diameter has no particular limits, but preferably in the scope at 0.1-6.0 dawn.Fibre diameter surpasses this scope, and the hidden performance of non-woven fabrics is just relatively poor, and the problem that body fluid sees through and quilt is seen of the bulk absorption of being absorbed is arranged.If discontented this scope of fibre diameter, fiber spacing is from just less, and it is residual to be produced body fluid by the effect of capillary attraction.
Nonwoven fabric sheet can adopt the imitative bonded nonwoven fabric made at the suction heat bonding non-woven fabrics of making after thermoplastic synthetic fiber's shredding on the carding machine, by melt spinning method or by non-woven fabrics of melt-blown etc.Surperficial cover of the present invention can be made of single non-woven fabrics, also can be with the thin slice of the various not perforates that non-woven fabrics and non-woven fabrics, non-woven fabrics/thin film or non-woven fabrics and other materials are combined into respectively.Nonwoven fabric sheet original thickness and weight per unit area before perforate not had no particular limits, but the wool spinning of thickness in the 0.2-2mm scope is furnished with feel and processing characteristics preferably, weight per unit area is at 15-45g/m
2Nonwoven in the scope is furnished with feel and processing characteristics preferably, and quality is more even.
The not perforate nonwoven fabric sheet of present embodiment adopts the suction heat bonding non-woven fabrics that is made of about (6 the dawn)-30wt% of PET/PE composite fibre (volumetric ratio is (40/60), about 2 dawn)-70wt%, PET with core pattern, and (the about 0.6mm of apparent thickness, weight per unit area are 20g/m
2).
As shown in Figure 2, at the surperficial 2A(and the contacted face of skin of surperficial cover 2) go up and form the trough part 13 that is the crest part 12 of convex curvature and between crest part 12 and crest part 12, is the concavity bending.The crest part 12 of surface cover 2 makes surperficial cover not have planar section ground to form many rows.Trough part 13 then is many rows, is made of the continuous face of crest part 12 between crest part 12 and crest part 12.Trough part 13 also is to make surperficial cover not have planar section ground to form many rows.Spacing (spacing between the row of adjacent trough part 13,13) between spacing between the crest part 12 (spacing between the row of adjacent crest part 12,12) and the trough part 13 is respectively 0.5-20mm, preferably 1.5-4.0mm.When surpassing this scope, the crest broad that partly becomes, rib crushes easily and makes rib become the plane when adding upward pressure; When being discontented with this scope, crest partly becomes too narrow, all can not form securely around crest part and the perforate.The sanitary towel that uses the physiology of the surperficial cover 2 of this structure to use has only the part of crest part 12 directly to contact with skin when wearing.
In the present embodiment, between the row of crest part between the row of spacing and trough part spacing P all be that 2mm(sees Fig. 2).
Form with ribbing 14 the perforate 15 of extending to the inside 2B from the surperficial 2A of surperficial cover 2 in trough part 13.The depth S of this perforate 15 be not perforate nonwoven fabric sheet thickness 1.1-3.0 doubly, preferably 1.2-2.5 doubly can be held in the distance between absorber and surperficial cover than large scale like this, just can not turned back on the sanitary towel surface by the body fluid of absorbent body.The diameter D of perforate 15 is 0.2-10mm, and preferably 0.5-1.5mm can be convenient to make body fluid such as blood not pass through like this with stockpiling.Discontented this scope of diameter, the fiber spacing that the size of perforate approaches non-woven fabrics from, in fact just do not form the effect in hole.When diameter D surpassed this scope, perforate was excessive, and skin just might directly contact absorber, thereby is bad.Each arranges spacing between the perforate 15 of adjacent with ribbing 14 on the trough part (spacings that with ribbing 14 the perforate on operating direction of surperficial cover is 15) is 0.4-40mm, preferably 1.5-8mm.When spacing surpassed this scope, the existence of perforate chap at interval will reduce the performance of passing through of liquid.When spacing was discontented with this scope, crest partly narrowed down, and the periphery of perforate just can not form securely.But this spacing is not owing to exist the crest part, thereby can get littler than the spacing between the crest part, forms the permeability that surperficial cover 2 with the perforate 15 of this rib 14 has body fluid such as blood preferably, do not have liquid to stockpile.And, if turning back to the inside one side of surperficial cover 2, can not see absorbed blood etc.
In the present embodiment, the diameter D of perforate is 1mm, and the depth S of perforate 15 is 2.0 times of (see figure 2)s of perforate nonwoven fabric sheet thickness not.
Below, describe above-mentioned rib 14 in detail, on the interior sidewall surface of above-mentioned perforate 15, form above-mentioned rib 14, above-mentioned perforate 15 is improved its intensity by this rib 14.Therefore, be meant in Fig. 2 at said in the present invention " rib 14 ", the non-woven fabrics on the perforate periphery have significantly differ the sheet thickness of perforate of S(S＞0.1 * not than perforate periphery at least to the inside) give prominence to the position.
That is, as shown in Figure 3,, make the thermoplastic synthetic fiber of rib 14 of the surperficial cover 2 that constitutes by above-mentioned nonwoven fabric sheet comparatively intensive, make harder than the non-woven fabrics (non-woven fabrics of crest part 12) of the part beyond the rib 14 by heating.Promptly have only the crest part 12 with skin directly contacts of convex can keep the distinctive soft hand feeling of non-woven fabrics; Be subjected to effects such as human pressure, have only rib 14 not damage by pressure like that in the perforate 15 rib 14 is made than partly firmer beyond the rib 14.
The of the present invention surperficial cover (perforate thin slice) 2 that is made of said structure is compared with perforate thin slice not, from the upper end of crest part to the apparent thickness of trough part lower end preferably 1.2-5.0 be 50g/cm doubly at pressure
2Preferably 1.1-4.0 times of thickness when .G, compressing.
The tension measuring device made from east (strain) company and the Kato dawn gram (strain) company the pressure test device to the rerum natura of present embodiment surface cover 2 and not the rerum natura of perforate nonwoven fabric sheet (operating direction (MD) and widthwise (CD)) measure, result such as table 1 are listed.Hot strength in the table 1 is to be standard with JISL10966.13, and apparent thickness is that standard is measured with JISL10968.5.Pressure is 50g/cm

Below, explain the manufacture method of the surperficial cover 2 of above-mentioned absorbing articles.
Above-mentioned surperficial cover 2 is the manufacturing technologies with known fiber interweaving, and above-mentioned known fiber is made non-woven fabrics, by with this non-woven fabrics mechanically perforate obtain.For example perforate non-woven fabrics not is inserted between the 1st pressing mold and the 2nd pressing mold and just can extrudes, the 1st pressing mold has a plurality of pyramid or conical convex pins of being, and they are to arrange line up side by side more; The 2nd pressing mold has the projecting strip part branch between the convex pin that is embedded in above-mentioned many rows.
The method that specific practice can utilize the applicant to put down in writing in the flat 5-16104 communique of the special hope of Japan Patent.As shown in Figure 4 and Figure 5, the nonwoven fabric sheet 20 of not perforate is clipped in along the throughput direction of nonwoven fabric sheet 20 has a plurality of pyramid or conical convex pins 22,22 of being ..., and these pins are pin roll 21(the 1st pressing molds of lining up many rows side by side) and the projecting strip part that has between the convex pin that is embedded in above-mentioned many rows divide 24,24 prominent bar roller 23(the 2nd pressing mold) between, just can pressure rolling form a plurality of perforates.
In this boring method, the convex pin 22 of pin roll 21 is not arrange along the throughput direction of perforate nonwoven fabric sheet 20 is lined up more, and these rows are provided with side by side.On the other hand, as shown in Figure 5, the projecting strip part of prominent bar roller 23 divide 24 be embedded in pin roll 21 each pin 22 between row and row.
Therefore, divide the 24 crest parts 12 that just can easily form surperficial cover 2, can form trough and divide 13 and perforate 15 and rib 14 and push nonwoven fabric sheet 20 by the convex pin 22 of pin roll 21 by the projecting strip part of prominent bar roller 23.Under this occasion, if being heated to 60-260 ℃, used again pin roll 21, then available energy makes the partly softening or partly fusion with the contacted non-woven fabrics in convex pin 22 peripheral parts (promptly forming the non-woven fabrics of rib), after convex pin 22 is extracted, just can make the rib 14 that part of non-woven fabrics that form surperficial cover 2 harder than the part beyond the rib.
In the forming process of the surperficial cover 2 of present embodiment, be the pin roll temperature to be set for 115 ℃ of ability nonwoven fabric sheet 20 is carried out perforate.
When being used in the surperficial cover made from method recited above 2 in the sanitary towel 1 that physiology uses, the sanitary towel 1 that this physiology is used has good feel, liquid permeability, resiliency and prevents the body fluid property returned.
Therefore, can draw such result, that is, and when surface of the present invention, when cover 2 is used in the sanitary towel 1 that physiology uses:
The first, the part that surperficial cover 2 contacts with skin is reduced, and, because the feel of the soft nonwoven before keeping with the contacted part of skin, thereby wearing and feeling good, and can reduce the moist feeling after wearing.
The second, because surperficial cover 2 is spatial structures, do not contain planar section or blood stockpiles part, thereby can make blood promptly be absorbed body 5 to absorb by perforate 15.
The 3rd because rib 14 is made than partly harder beyond the rib, even thereby surperficial cover be subjected to the human pressure, the thickness of rib can attenuate, and resiliency is preferably arranged.Thus, can keep surperficial cover 2 and absorber 5 or and intermediate layer 4 between certain intervals, eliminating substantially, body fluid such as absorbed blood returns from the surperficial 2A of absorber 5 to surperficial cover 2.
Present embodiment is that surperficial cover 2 is used in the sanitary towel 1 that physiology uses, but the purposes of this surperficial cover is not limited to these, and it can be used in the absorbent commodity as papery diapers such as diaper certainly.
