Embodiment 1

[0023] Such as figure 1 The concave-convex air-through non-woven fabric shown is made of low-melting bicomponent fibers with a linear density of 1.2-6D and a length of 38-65mm. The surface layer is provided with a plurality of convex points 1 that protrude upwards. The convex points 1 are water-repellent. Between the adjacent convex points 1 is an inner concave surface 2. The inner concave surface 2 is hydrophilic. The water repellency of the connecting surface 3 gradually decreases from top to bottom, which not only ensures the comfort of use, but also improves the speed of infiltration, and the surface layer made of it has a good use effect.

[0024] Concavo-convex air-through non-woven fabrics are produced by the following steps in sequence:

[0025] (1) Choose low-melting bicomponent fibers with a linear density of 1.2-6D and a length of 38-65mm, where the bicomponent fiber can be one of PE / PP, PE / PET, PP / PP, CoPET / PET , or a mixture of the two, the two-component structu...

Embodiment 2

[0030] Application of concave-convex air-through non-woven fabric on diapers, the concave-convex air-through non-woven fabric described in Example 1 is used as the surface layer of diapers. The paper diapers comprise an outer cover and a core therein. The outer cover includes a bottom layer and the concave-convex air-through nonwoven fabric described in Example 1. The advantage of the patent paper diaper is that it is comfortable to use and can prevent the occurrence of red buttocks.

[0031] During production, on the diaper production equipment, the concave-convex hot-air non-woven fabric described in Example 1 is unrolled, and the lower non-woven fabric, flow guide layer, composite core body, side leakage-proof partition and anti-seepage bottom film are unrolled. After compounding, dry and comfortable diapers are obtained. For the diapers of this patent, first, multiple hydrophilic low-melting bicomponent fibers are made into multiple hydrophilic air-through non-woven fabri...

Abstract

The invention relates to the field of non-woven fabric materials, in particular to a concave-convex hot-air non-woven fabric. The raw material of the concave-convex hot-air non-woven fabric is repeatedly hydrophilic bi-component fiber, a surface layer is provided with a plurality of hydrophobic convex points protruding upwards, and hydrophilic convex surfaces are arranged between the adjacent convex points. The concave-convex hot-air non-woven fabric has the advantages that the absorption and infiltration speed is high, and the surface layer is dry and comfortable.

Description

technical field [0001] The invention relates to the field of non-woven fabric materials, in particular to a concave-convex hot-air non-woven fabric used as the surface layer of diapers. Background technique [0002] Many surface layers of paper diapers adopt 3D embossing structure, such as the Chinese patent whose publication number is CN203677388U, the title is a diaper with a 3D three-dimensional embossed surface layer, and a plurality of 3D three-dimensional embossed patterns are distributed on the surface layer. Due to the addition of 3D three-dimensional embossing, the surface of the diaper is more beautiful and the contact area between the baby's buttocks and the diaper is reduced, thereby enhancing the breathability and making the baby healthier and more comfortable during the use of the diaper. [0003] At present, the surface layer of diapers on the market is mostly made of short-fiber air-through non-woven fabrics and PP spunbonded non-woven fabrics. Because the su...
