Description

A kind of composite ventilating counterdie

Technical field

The utility model relates to disposable absorbent article technical field, in particular to a kind of composite ventilating counterdie.

Background technique

Infant and other people that can't take care of oneself are often required to wear disposable absorbent article, such as diaper.Disposably The function of absorbent article is that it can accommodate excreta, and keeps apart the body of these excretas and wearer and clothes and bedding Come.Disposable absorbent article, such as diaper, usually by fluidity surface layer, opaque liquid bottom and set on permeable top layer and not The absorptive core composition for absorbing and liquid capable of being accommodated between liquid permeability bottom.Therefore, absorptive core is disposable absorbent article Core component, play the role of absorption and receive body fluid carrier.

However, increase the snugness of fit of absorbent article to improve the Air permenbility of ventilated membrane, the usually packet by the way of The ventilative hole increased on ventilated membrane is included, or increases the quantity of ventilative hole, but with the increase of ventilative hole, it is ventilative stretching It may cause adjacent hole when film and be merged into macropore because of tearing, it is seen that although these modes improve the ventilative of ventilated membrane Property, but seepage of water is also resulted in, cause existing composite ventilating counterdie to lead to composite ventilating counterdie outer layer due to the infiltration of moisture (nonwoven layer) sense of touch is extremely moist, or even the situation of the leakage of body fluids easily occurred when long-time uses absorbent article, greatly The quality and wearing comfort of absorbent article are reduced greatly.

The utility model by the way that moisture absorption layer is arranged between film layer and nonwoven layer ventilative, by the moisture absorption layer capture, The moisture infiltrated from ventilative film layer is absorbed, increases the dry-ness of composite ventilating counterdie outer layer, by setting to nonwoven layer Raised line is set to increase vapor permeation area, the Air permenbility of composite ventilating counterdie is improved, improves the suction using the composite ventilating counterdie Receive the gas permeability and wearing comfort of product.

Summary of the invention

The purpose of this utility model is that how to improve the gas permeability of compound breath film, and how to keep composite ventilating bottom Film outer layer it is dry-ness.To achieve the above objectives, the present invention adopts the following technical solutions:

The composite ventilating counterdie, including ventilative film layer and nonwoven layer, including following structure feature:

Firstly, being provided with moisture absorption layer between the ventilative film layer and nonwoven layer, the width along the moisture absorption layer is horizontal Interconnecting piece is set to direction interval, the ventilative film layer and nonwoven layer are connected as one by the interconnecting piece, adjacent Moisture absorption item is set between two interconnecting pieces, and the interconnecting piece, moisture absorption item are past each along the length longitudinal direction of the moisture absorption layer Both ends extend.

Secondly, plural item pleurapophysis to outside nonwoven layer is arranged along the width transverse direction interval of the nonwoven layer Raised line out, each raised line extend along the length longitudinal direction of the nonwoven layer toward both ends, two adjacent institutes It states and is parallel to each other between raised line.

Preferably, the interconnecting piece is hot melt adhesive coating, and the moisture absorption item is high hygroscopicity fibre beam.

Preferably, setting thermal bonding point, the thermal bonding are respectively separated in two longitudinal side of bottom of each raised line The distribution trajectory of point extends along longitudinal side to both ends.

Preferably, the thermal bonding point is overlapped between two adjacent raised lines.

Preferably, the width of the raised line is 0.5-5mm, is highly 0.2-3mm.

Preferably, the thermal bonding is the dot of diameter 0.5-1.0mm.

Preferably, embossed area is set between two adjacent raised lines, the embossed area is embossed by hexagon It constitutes.

Preferably, the nonwoven layer is using spun-bonded non-woven or Nonwovens as substrate.

The advantageous effects of the utility model: the moisture absorption layer of the utility model can capture, absorb and seep from ventilative film layer The moisture come is appeared, to remove contained humidity when air is spread by absorbent article interior, and is located at nonwoven layer On raised line increase vapor permeation area, improve the Air permenbility of composite ventilating counterdie, therefore, the utility model is in moisture absorption layer, convex The collaboration of item improves the gas permeability of composite ventilating counterdie, on the one hand, avoids existing composite ventilating counterdie due to the infiltration of moisture Cause composite ventilating counterdie outer layer (nonwoven layer) sense of touch moist thoroughly, or even is occurred in long-time using absorbent article On the other hand the situation of leakage of body fluids improves the gas permeability and wearing comfort of the absorbent article using the composite ventilating counterdie Property.

Specific embodiment

The utility model patent is further described with reference to the accompanying drawing.

As shown in attached drawing 1, Fig. 2 and Fig. 3, the composite ventilating counterdie of the utility model, including ventilative film layer 1 and non-woven cloth Layer 3, and there is following structure feature:

As shown in Fig. 1, it is provided with moisture absorption layer 2 between ventilative film layer 1 and nonwoven layer 3, along the moisture absorption layer 2 Interconnecting piece 21 is arranged in width transverse direction interval, which is connected as one ventilative film layer 1 and nonwoven layer 3, Between two adjacent interconnecting pieces be arranged moisture absorption item 22, interconnecting piece 21, moisture absorption item 22 each along the moisture absorption layer 2 length longitudinal direction side Yearn for both ends to extend.

In a specific embodiment, the interconnecting piece 21 of the present embodiment is hot melt adhesive coating, and moisture absorption item 22 uses high-hydroscopicity Fibre bundle.The high hygroscopicity fibre beam is current material, has the ability for absorbing 10-60 times of physiological saline of its own weight.

As shown in attached drawing 2, Fig. 3, the utility model is arranged also along the width transverse direction interval of nonwoven layer 3 to non- Raised line 31 outstanding on the outside of woven layer, including raised line 31a, raised line 31b, raised line 31c, raised line 31d, each raised line is each along institute The length longitudinal direction for stating nonwoven layer extends toward both ends, forms raised line 31a parallel between each other, raised line 31b, raised line 31c and raised line 31d, and plain area 33 is formed between two adjacent raised lines.

In a specific embodiment, the raised line such as raised line 31a, raised line 31b, raised line 31c and raised line 31d, are knitted so that spunbond is non- It makes cloth or Nonwovens is substrate, by the substrate by a pair of convex roller and smooth roll being mutually twisted, the shape through integrated molding At with parallel raised line 31a, raised line 31b, raised line 31c and raised line 31d.Wherein, the width of raised line is 0.5-5mm, is highly 0.2-3mm。

In order to enable raised line can be better maintained shape stability, the utility model is in two longitudinal side of the bottom of raised line Thermal bonding point is set to play the role of fixing and supporting to raised line.As shown in attached drawing 2, Fig. 3, in the bottom of each raised line Two longitudinal sides, are respectively separated setting thermal bonding point 32, and the distribution trajectory of the thermal bonding point 32 is along longitudinal side to both ends Extend.Specific embodiment is as follows:

The closely joining place of plain area 33 and raised line, the heat that row's longitudinally spaced distributions are arranged in plain area 33 connect Chalaza 32, when it is implemented, by pressure roller heat pressure adhesive formed thermal bonding point 32, as thermal bonding point 32 be diameter 0.5-1.0mm, Shape is that ultrasonic bonds point, the hot-rolling of dot press bounding point or laser heats junction.
