The specific embodiment
The invention provides the surface patch of absorbent commodity, it is compared with the surface patch of above-mentioned conventional art, has improved buffering sense, soft feeling, and is difficult for producing the reverse osmosis of liquid.
Below based on its embodiment preferred, the present invention will be described with reference to accompanying drawing.Fig. 1 represents the sketch map of stravismus state of the surface patch of absorbent commodity of the present invention, the sketch map in II-II line cross section in Fig. 2 presentation graphs 1.The surface patch 1 of the present embodiment can be used as the surface patch of the sanitary towel of absorbent commodity one example.When packing this surface patch 1 into sanitary towel, surface patch 1 is made of the upper strata non-woven fabrics 2 with the skin side that is configured in wearer, the stacked non-woven fabrics of lower floor's non-woven fabrics 3 that is configured in the absorption side of sanitary towel.On surface patch 1, form to connect both a plurality of liquid of upper strata non-woven fabrics 2 and lower floor's non-woven fabrics 3 by hole 4.Liquid is surrounded and is formed to absorbing stacked non-woven fabrics that side (below side) extends out from the skin side (upper face side) of surface patch 1 by hole 4.The perforate end 4a of liquid by hole 4 is to there not being illustrated absorber direction outstanding.Liquid passes through the continuous face formation of the inwall in hole 4 by the face of the skin side (upper face side) of surface patch 1.
Upper strata non-woven fabrics 2 and lower floor's non-woven fabrics 3 at least liquid by hole 4 around, i.e. perforate end 4a and near the joint thereof of liquid by hole 4.Liquid by hole 4 around beyond part, upper strata non-woven fabrics 2 and lower floor's non-woven fabrics 3 can not engage in fact, perhaps can engage.The so-called joint is meant the fibre machinery ground that constitutes levels non-woven fabrics 2,3 mixings that interlock, perhaps pass through to heat soften, fusion, perhaps with combinations such as bonding agents.In addition, what is called does not engage in fact, be not only upper strata non-woven fabrics 2 and lower floor's non-woven fabrics 3 complete isolating states, contact with lower floor non-woven fabrics 3, impose on the segregative state of power of the sort of degree of surface patch 1 in dressing with sanitary towel though also comprise upper strata non-woven fabrics 2.
By 4,4 in hole, upper strata non-woven fabrics 2 and lower floor's non-woven fabrics 3 all are arcuation towards skin side protuberance at liquid.In addition, between upper strata non-woven fabrics 2 and lower floor's non-woven fabrics 3 and the downside that is positioned at lower floor's non-woven fabrics 3 form the 1st space 5a, the 2nd space 5b respectively.In addition, when integral body is seen surface patch 1, on this surface patch 1, be formed with a plurality of protrusions 6 to skin side protuberance.Protrusion 6 is by being that upper strata non-woven fabrics 2 and lower floor's non-woven fabrics 3 of arcuation constitutes to skin side protuberance separately.
In addition as shown in Figure 2, on lower floor's non-woven fabrics 3, be formed with a plurality of little protuberances 7 for the part of arcuation at protuberance.Little protuberance 7 forms by being out of shape as the lower floor's non-woven fabrics 3 as the rips that rises.Separate with the following side contacts of upper strata non-woven fabrics 2 or with it on the protuberance top of little protuberance 7.Especially when below the protuberance top of little protuberance 7 and the upper strata non-woven fabrics 2 during side contacts, has the advantage that liquid becomes good from upper strata non-woven fabrics 2 to the mobility of lower floor's non-woven fabrics 3.In addition, the protuberance of upper strata non-woven fabrics 2 also has by the on-deformable advantage of little protuberance 7 supports for the shape of arcuation.
Like this, the two-layer structure that protrusion 6 becomes by upper strata non-woven fabrics 2 and lower floor's non-woven fabrics 3 constitutes, between two-layer nonwoven, form the 1st space 5a, therefore when the body pressure of wearer is applied on the surface patch 1, the at first arch shape distortion of upper strata non-woven fabrics 2 formation, this deformation process of 2 sections is experienced in the arch shape distortion of lower floor's non-woven fabrics 3 formation then.Therefore, the buffering sense of the surface patch 1 of the present embodiment, soft feeling excellence, and in case be absorbed the liquid that body (not shown) absorbs and be difficult for to surface patch 1 side adverse current.That is, be difficult for producing so-called " anti-wet (wet back) ".
In addition, be applied on the surface patch 1 even the body of wearer is pressed, a plurality of little protuberance 7 that lower floor's non-woven fabrics 3 forms plays a role as the support sector that stops 2 distortion of upper strata non-woven fabrics, therefore keeps arch shape to become easy.Therefore, if see that as protrusion 6 integral body its projecting shape is stably kept.Consequently, the surface patch 1 of the present embodiment can reduce the contact area between the skin side surface of the skin of wearer and surface patch 1, can prevent the generation of discomfort, and make aeration keep good.
From stop the viewpoint of the distortion of upper strata non-woven fabrics 2 by the little protuberance 7 of lower floor's non-woven fabrics 3 formation, lower floor's non-woven fabrics 3 preferably is made of the high non-woven fabrics of rigidity.On the other hand, from the viewpoint of the distortion that stops upper strata non-woven fabrics 2, preferred upper strata non-woven fabrics 2 also is made of the high non-woven fabrics of rigidity, if but improve rigidity, then the feel of non-woven fabrics descends easily.Therefore, in the surface patch 1 of the present embodiment, be higher than upper strata non-woven fabrics 2, preventing the arch shape distortion by lower floor's non-woven fabrics 3 when, can embody good hand feeling by upper strata non-woven fabrics 2 by the rigidity that makes lower floor's non-woven fabrics 3.
In order to improve the rigidity of lower floor's non-woven fabrics 3, for example improving it quantitatively is effectively, in this case, reduces easily as the feel of surface patch 1 integral body, and can not say favourable from making the funds viewpoint.Therefore, in the present embodiment, as lower floor's non-woven fabrics 3, the preferred non-woven fabrics that has carried out embossing processing that uses.On the other hand, about upper strata non-woven fabrics 2, from improving the viewpoint of feel, the non-woven fabrics of embossing processing is not carried out in preferred use.
Specifically, as upper strata non-woven fabrics 2, can use hot blast (air-through) non-woven fabrics (not carrying out embossing processing) as the good non-woven fabrics of feel.In this case, formation aspect, the feel aspect of the arch shape that forms from upper strata non-woven fabrics 2 are made funds aspect etc. and are set out, preferred hot-wind nonwoven cloth quantitatively be 10～40g/m
2, be preferably 20～35g/m especially
2About.On the other hand, as lower floor's non-woven fabrics, the hot-wind nonwoven cloth that embossing is processed, spun bond nonwoven fabric/meltblown non-woven fabrics/spunbonded type compound nonwoven cloth etc. have for example been carried out in preferred use.In spun bond nonwoven fabric/meltblown non-woven fabrics/spunbonded type compound nonwoven cloth, general enforcement embossing processing in its manufacturing process.From keeping the feel of surface patch 1 integral body, improve the inflexible viewpoint of lower floor's non-woven fabrics 3 simultaneously and set out, preferably that lower floor's non-woven fabrics 3 quantitatively is 10～50g/m

As levels non-woven fabrics 2,3 employed fibers, can enumerate for example polyethylene (PE), polypropylene (PP), such polyester and the such synthetic fibers such as polyamide of nylon of polyethylene terephthalate (PET), regenerated celulose fibres such as artificial silk and cuprammonium short fiber, and natural fiber such as cotton, but be not limited to these.In addition, preferably use with the high fiber of fusing point as core and with low-melting fiber as composite fibres such as the core-sheath-type fiber of sheath, bilateral fibre, Splittable fibers etc.These fibers can use a kind or 2 kinds or multiple.The pigment such as titanium oxide that can cooperate ormal weight as required in these fibers improve the disguise of surface patch 1.
As shown in Figure 1, protrusion 6 is disposed and is formed separately independently island discretely.In addition, each protrusion 6 forms row on the operating direction MD of surface patch 1, be configured to multiple row.And, from the aspect that stably forms protrusion 6 and embody the buffering sense that protrusion 6 produces, the viewpoint of soft feeling effectively, the interval (interval between the summit of protrusion 6) that preferred mechanical direction MD goes up adjacent rises 6 is 1～10mm, is preferably 2～5mm especially.Upward the interval (interval between the summit of protrusion 6) of adjacent rises 6 also can be same for width CD.
The operating direction arranging line L at the center by each protrusion 6
MDWith width arranging line L
CDMutually orthogonal, these arranging lines form clathrate.In addition, liquid is positioned at by operating direction arranging line L through hole 4
MDWith width arranging line L
CDIn the rectangle that marks off.Therefore, can flow down to any direction of its front and back and left and right directions by the inclined-plane of protrusion 6 from the excretory liquid of wearer, so liquid is promptly removed from the surface of protrusion 6.The liquid that flows down promptly penetrates into absorber by the liquid that is positioned at 6 of protrusions by hole 4.Consequently, liquid is difficult at the skin side surface of surface patch 1 residual.From this viewpoint, preferably each liquid is 0.2～20mm through hole 4 at the area of its perforate end 4a
2About, be preferably 0.5～10mm especially
2About.In addition, the percent opening that liquid sees through hole 4 be preferably 5% or more than, be preferably especially 7% or more than, more preferably 10～20%.From stably forming the viewpoint that liquid sees through the aspect in hole 4 and guarantees the sufficient permeability of liquid, preferred mechanical direction MD goes up the 1～10mm that is spaced apart that adjacent liquid sees through hole 4, is preferably 2～5mm especially.Width CD goes up adjacent liquid also can be same through the interval in hole 4.
From the permeability of further raising liquid, the difficult viewpoint that produces of liquid residue of the skin side surface of surface patch 1 is set out, preferably between upper strata non-woven fabrics 2 and lower floor's non-woven fabrics 3, there is the capillary force gradient.Specifically, preferably make lower floor's non-woven fabrics 3 littler than the fiber footpath (fiber number) of the formation fiber of upper strata non-woven fabrics 2.From permeability that improves liquid and the viewpoint that prevents liquid residue, liquid countercurrent, the difference in the fiber footpath (fiber number) between preferred levels non-woven fabrics is 1～4dtex, more preferably 2～3dtex.In this case, the fiber of upper strata non-woven fabrics 2 is preferably 0.8～5dtex, is preferably the fiber number of 1.5～3.3dtex especially.The fiber of lower floor's non-woven fabrics 3 is preferably 0.1～3.5dtex, is preferably the fiber number of 0.5～2.5dtex especially.
When in the levels non-woven fabrics, using the fiber in identical fibre footpath, there is the capillary force gradient in order to make between upper strata non-woven fabrics 2 and the lower floor's non-woven fabrics 3, preferably make the fibre density height of the fibre density of lower floor's non-woven fabrics 3 than upper strata non-woven fabrics 2.The fiber of the levels non-woven fabrics of this moment is preferably 0.8～5dtex, is preferably the fiber number of 1.5～3.3dtex especially.In addition, even have hydrophilic gradient between upper strata non-woven fabrics 2 and lower floor's non-woven fabrics 3, the permeability of liquid also improves, and also is difficult for being created in the liquid residue of the skin side surface of surface patch 1.Specifically, preferably make the hydrophilic of lower floor's non-woven fabrics 3 than upper strata non-woven fabrics 2 height.

The surface patch 1 for example method manufacturing of following explanation of preferred employing of the present embodiment.Fleece is inserted through between the metal porcupine roller and plain-barreled roll of heating, makes this fleece non-woven fabricsization, when obtaining lower floor's non-woven fabrics 3, on this lower floor's non-woven fabrics 3, form a plurality of little protuberances.Replace this method, hot-wind nonwoven cloth is inserted through between the metal protruding roller and backing rolls such as cotton roller, rubber rollers of heating, prepare and given concaveconvex shape lower floor non-woven fabrics 3.Perhaps hot-wind nonwoven cloth is inserted through and has formed a plurality of concavo-convexly and become between metal one group of roller of mutual interlock shape, implement steel plate and cooperate (steel match) embossing processing, obtained giving lower floor's non-woven fabrics 3 of concaveconvex shape.Example by lower floor's non-woven fabrics 3 of these methods preparation is shown in Fig. 3 (a) and Fig. 3 (b) respectively.Lower floor's non-woven fabrics shown in these figure only can be used for an example of surface patch of the present invention, does not limit and uses this illustration lower floor's non-woven fabrics in addition.
Lower floor's non-woven fabrics 3 shown in Fig. 3 (a) is a wave-like, and a plurality of little protuberance 7 that is made of ridge portion forms to a direction.On the other hand, in the lower floor's non-woven fabrics 3 shown in Fig. 3 (b), form the independently a plurality of separately little protuberances 7 that are distributed as island.Under Fig. 3 (a) and both situations of Fig. 3 (b), if the fibre density of smaller protuberance 7 and its neighboring area, exist by adopting which type of method to form little protuberance 7 the high situation of fibre density of situation that the fibre density of little protuberance 7 is high and opposite neighboring area.From improving the viewpoint of the resiliency that little protuberance 7 produces, the fibre density of preferred little protuberance 7 is lower than the fibre density of neighboring area.
Upper face side coating hot-melt adhesive at the lower floor's non-woven fabrics 3 for preparing like this.As rubbing method, can enumerate for example spiral coating, the coating of curtain formula, multiple row seed pearl coating (multi-row beadcoating) etc.Then, this lower floor's non-woven fabrics 3 and upper strata non-woven fabrics 2 are fitted, obtain stacked non-woven fabrics.
Then, stacked non-woven fabrics is inserted through the roller that plants a plurality of peckers and be equipped with and the roller in the hole that this pecker is chimeric between, make levels non-woven fabrics protuberance form protrusion 6 in by the hole forming liquid.In addition, upper strata non-woven fabrics 2 and lower floor's non-woven fabrics 3 are liquid being bonded with each other on every side by hole 4.In addition owing to adopt in the operation hot-melt adhesive that the levels non-woven fabrics is fitted in front, so the levels non-woven fabrics liquid by hole 4 around beyond part also engage.The device that possesses above-mentioned roller is opened in the clear 62-125061 communique on the books for example spy.
The surface patch 1 of the present embodiment it can be disposed at sanitary towel absorber the skin side comprehensively on.Perhaps can only be configured on the part of skin side of absorber.For example sanitary towel 10 as shown in Figure 4 is such, and the surface patch 1 of middle section 11 usefulness the present embodiment of width in the surface patch is constituted.In this case, preferably in respect to each lateral region 12 of middle section 11, form the 2nd low protrusion of the protrusion that forms on the aspect ratio middle section 11 6.Like this, in middle section 11 and lateral region 12, produce difference on buffering sense, soft feeling, it is more remarkable that the buffering sense of middle section 11, soft feeling become.Particularly preferably, if form the 2nd protrusion with the higher density of density that exists than the protrusion 6 that forms in the middle section 11 on lateral region 12, buffering sense, soft feeling further become remarkable.
The portion of extending out that lateral region 12 can be extended to the side by the surface patch 1 of the present embodiment that forms middle section 11 constitutes, and the surface patch 1 that perhaps forms the present embodiment of middle section 11 can be made of the sheet material of other material.From easiness of making and the junction viewpoint that does not have the generation of fitting, preferred lateral region 12 is made of the portion of extending out of the surface patch 1 of the present embodiment that forms middle section 11.In this case, lateral region 12 can both constitute by upper strata non-woven fabrics 2 and lower floor's non-woven fabrics 3, perhaps are made of either party of levels nonwoven portion.From the viewpoint of the feel that improves lateral region 12,12 of preferred lateral region are extended out to the side by the upper strata non-woven fabrics 2 of the surface patch 1 that constitutes middle section 11 and constitute.
For extending out to the side, the upper strata non-woven fabrics 2 in the surface patch 1 that only makes formation middle section 11 constitutes lateral region 12, in the various manufacture methods of surface patch 1 described later, can make the width of upper strata non-woven fabrics 2 bigger than the width of lower floor non-woven fabrics 3, form surface patch 1 for two non-woven fabrics intersection, and the part that extends out of use upper strata non-woven fabrics 2 is as zone, side 12.
Ground as described above is such, and the 2nd protrusion that forms in lateral region 12 can be made of the non-woven fabrics of two coincidences, perhaps is made of a slice non-woven fabrics.When the 2nd protrusion was made of the non-woven fabrics of two coincidences, the 2nd protrusion can be identical formation with protrusion in the surface patch 16, perhaps is the formation different with it.
In lateral region 12,, preferably except forming the 2nd protrusion, between the 2nd protrusion, form the 2nd liquid and pass through the hole from the viewpoint of the permeability of further raising liquid.From this viewpoint, preferred the 2nd liquid by the hole to form than the higher density of density that exists of the liquid that forms at middle section 11 by hole 4.
Extend out forms the 2nd liquid to absorbing side (below side) from skin side (upper face side) by the non-woven fabrics of hole by constituting zone, side 12.Its perforate end is outstanding to the direction of absorber.The inwall of the 2nd liquid by the hole is made of the continuous face from the face of the skin side (upper face side) of the non-woven fabrics that constitutes zone, side 12.The liquid that forms in this structure and the middle section 11 is same by hole 4.
In the zone, side 12 the 2nd protrusion and the 2nd liquid see through the configuration in hole can be same by the configuration in hole 4 with protrusion 6 in the surface patch 1 of the present embodiment and liquid.In addition, the 2nd protrusion and the 2nd liquid formation method that sees through the hole also can be identical with the formation method that liquid sees through hole 4 with protrusion 6 in the surface patch 1 of the present embodiment.
Followingly the of the present invention the 2nd～4 embodiment is described with reference to accompanying drawing 5～Fig. 8.For these embodiments related but do not have the aspect that specifies, suitablely use the explanation of being described in detail in the 1st embodiment.In addition, in Fig. 5～Fig. 8, the parts mark same-sign identical with Fig. 1～Fig. 4.
The surface patch 1 of the 2nd embodiment shown in Figure 5, protrusion 6 is different with the 1st embodiment with the configuration that liquid sees through hole 4.Arrange a plurality of ridge portions 8 and ditch portion 9 in the surface patch 1 of the present embodiment mutually so that it does not have planar portions.Ridge portion 8 is bent into convex and ditch portion 9 bends to concavity.That is, in the surface patch 1 of the present embodiment, the summit of a plurality of protrusions 6 is shown linearity greatly and is connected continuously, constitutes ridge portion 8.Form ditch portion 9 between the adjacent ridge portion 8,8.By forming ridge portion 8 and ditch portion 9, can give the direction parallel with ridge portion 8 and ditch portion 9 and with their rectangular directions on flexural property (for example bulk soft (bulk softness) etc.) anisotropy, can improve fitness, the feel of surface patch 1 and health.
In the surface patch of the present embodiment, the bearing of trend of ridge portion 8 and ditch portion 9 is preferably consistent with the length direction of the absorbent commodity of the surface patch 1 that uses the present embodiment.But, be not limited to this.Operating direction when ridge portion 8 can make with the levels non-woven fabrics 2,3 of grey cloth with ditch portion 9 is consistent, perhaps also can be inconsistent.
The surface patch 1 for example method manufacturing of following explanation of preferred employing of the present embodiment.For manufacturing, the processing method of lower floor's non-woven fabrics 3, identical with the 1st embodiment, form Fig. 3 (a) of for example illustrating previously and (b) shown in non-woven fabrics.Then, overlap with lower floor's non-woven fabrics 3 of preparation like this with its upper strata non-woven fabrics 2 of making in addition, 2 non-woven fabrics that make coincidence are between the 1st pressing mold and the 2nd pressing mold.The 1st pressing mold is made of porcupine roller, and this porcupine roller has to be arranged side by side along a plurality of convex pins of the carrying direction Cheng Liezhuan pyramid of non-woven fabrics or cone shape and this row and is multiple row.The 2nd pressing mold is made of prominent bar roller, and this prominent bar roller has the projecting strip part between the convex pin that embeds multiple row in the 1st pressing mold.The pressing mold of this formation leaves in the flat 6-330443 communique on the books the applicant the spy of first to file.
In this manufacture method, the convex pin of porcupine roller becomes row along the carrying direction of levels non-woven fabrics, and these row are arranged side by side and are multiple row.On the other hand, between the row and row of each convex pin of the projecting strip part of prominent bar roller embedding porcupine roller.Consequently, the projecting strip part by prominent bar roller forms the ridge portion 8 that protrusion 6 links to each other easily, and because the convex pin of porcupine roller penetrates in the levels non-woven fabrics, forms liquid by hole 4.In this case, porcupine roller is heated to 60～260 ℃, peripheral part ground that makes liquid pass through hole 4 softens or partly dissolving, around this levels non-woven fabrics is bonded with each other.In addition, for zygosity of improving the levels non-woven fabrics etc., before the levels non-woven fabrics that will overlap imports between the above-mentioned roller, for example, also preferred enforcement (for example blows hot blast to the levels non-woven fabrics of coincidence, 60～260 ℃), perhaps the levels nonwoven fabric roll that overlaps is got the first-class The pre-heat treatment that well known to a person skilled in the art of preheat roll (for example, 60～260 ℃).
In this manufacture method, can before 2 non-woven fabrics that will overlap be between the 1st pressing mold and the 2nd pressing mold, carry out the embossing processing in advance and make two non-woven fabrics (discontinuously) joint discontinuously.During handling, embossing uses the embossing device that constitutes by porcupine roller that heats and plain-barreled roll.In this case, make the interval of the pin of width in the porcupine roller bigger than the interval of the width of projecting strip part in the interval of the width of convex pin in aforesaid the 1st pressing mold, the 2nd pressing mold.Carry out embossing handle two non-woven fabrics are engaged after, it is carried out aforesaid processing between the 1st pressing mold and the 2nd pressing mold.Make levels non-woven fabrics protuberance pass through hole 4 like this for arcuation and at the spatial liquid that forms simultaneously that forms the 1st and the 2nd.In the surface patch 1 that forms like this, be not only liquid by around the hole 4, also engage at other parts levels non-woven fabrics.In addition, the protuberance front end of the little protuberance 7 that forms in the part that bulges into arcuation of lower floor's non-woven fabrics 3 becomes the state of side contacts below upper strata non-woven fabrics 2.
