Problems solved by technology

However, the above method only makes the wearer feel more comfortable, and does not essentially solve the problem of rapid liquid diffusion, and the manufacturing process is complicated
[0005] There are also small holes in the liquid-receiving surface layer of some absorbent articles, so that the liquid that flows onto the surface layer is absorbed by the liquid-absorbing layer through the openings. The liquid passage of this surface layer is good, and the contact area with the skin It has also been reduced, and the dryness performance is better than that of the same material without openings. However, for the air-through non-woven fabric with openings, liquid will still remain in the fluffy fiber gaps, which will easily make the skin feel moist.
[0006] Moreover, when the absorption layer of the existing absorber is arranged from top to bottom, the denser non-woven fabric is often on the top, and the loose guide layer is on the bottom, so it is difficult to make the liquid diffuse rapidly.

Embodiment 1

[0031] Such as figure 1 As shown, a multi-component one-time molding air-through non-woven fabric is composed of several layers of fiber lamination. Specifically, the air-through non-woven fabric finally formed by fiber lamination has a structure that gradually changes from loose to dense from top to bottom. The coarse fiber layer faces the skin and the dense fine fiber layer faces the core.

[0032] Its production process is as image 3 As shown, first select 15 grams per square meter of fibers with deniers of 0.8 tex, 2 tex, and 3.2 tex respectively, and open them on the opener respectively, then card them separately, and then loosen them according to the above. Three kinds of fiber layers are laminated in the order of coarse fiber and dense fine fiber. It is then sent to an oven for drying and shaping, and finally forms a structure that gradually changes from the upper loose layer 1 to the lower dense layer 2. Finally, the air-through non-woven fabric prepared by thermof...

Embodiment 2

[0034] Such as figure 2 As shown, repeating Example 1, only further, in order to make the liquid quickly diffuse to the bottom of the surface layer, and at the same time lock the liquid, there are hot-rolled pits 3 on the multi-component once-molded hot-air non-woven fabric, The liquid can be concentrated at the pit 3 . Its hot rolling process is in such as image 3 The thermoforming step shown is completed. After the laminated fiber layers are sent to an oven for drying and shaping, the multi-component laminated fiber layers are hot-rolled to form the pits 3 .

[0035] When the multi-component one-time forming air-through non-woven fabric described in any of the above embodiments is used, the side of the loose thick fiber faces the skin, and the side of the dense fine fiber faces the core. When the liquid encounters the surface layer, due to capillary action, The liquid will quickly spread from the upper loose layer 1 to the lower dense layer 2 of the surface layer, so tha...

Abstract

A multi-component integrally formed hot air non-woven fabric comprises a plurality of layers of stacked fibers, specifically, the hot air non-woven fabric finally made of the stacked fibers is in a structure gradually becoming dense from loose from top to bottom, loose crude fibers face the skin, and dense fine fibers face a core body. Meanwhile, the invention further provides a manufacturing method of the multi-component integrally formed hot air non-woven fabric. The multi-component integrally formed hot air non-woven fabric provided by the invention has the characteristics of rapid absorption and diffusion, large absorbing area, and dry and clean contact surface.

Description

technical field [0001] The invention relates to the field of personal hygiene products, in particular to a multi-component once-formed air-through nonwoven fabric and a manufacturing method thereof. The air-through nonwoven fabric of the present invention can be used as the surface layer material of absorbent products such as sanitary napkins and disposable diapers. Background technique [0002] For the surface layer of absorbent articles such as sanitary napkins and disposable diapers, the required functions are good liquid permeability, less liquid left on the surface absorbed by the absorbent layer, good dryness, not easy to reverse seepage, soft touch, skin Contact irritation is small. [0003] At present, there are roughly two types of surface materials used in absorbent products such as sanitary napkins and disposable diapers on the market: one is spunbonded non-woven fabric, which has better dry performance, but the disadvantage is that it is not soft enough and comf...
