Example Embodiment

[0022] Example 1

[0023] Such as figure 1 The concave-convex hot-air non-woven fabric shown is made of low-melting bi-component fibers with a linear density of 1.2-6D and a length of 38-65mm as raw materials. The surface layer is provided with a plurality of convex points 1 that protrude upward. The convex points 1 are water-repellent. The inner concave surface 2 is between the adjacent convex points 1, and 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 increases the speed of infiltration, and the finished surface layer has a good use effect.

[0024] Concave-convex hot air non-woven fabrics are produced in sequence using the following steps:

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

Example Embodiment

[0029] Example 2

[0030] Application of concave-convex hot-air non-woven fabric on diapers, the concave-convex hot-air non-woven fabric described in Example 1 is used as the surface layer of diapers. The paper diaper includes an outer cover and a core inside. The outer cover includes a bottom layer and the concave-convex hot-air non-woven fabric described in Example 1. The advantages of the patented diapers are that they are comfortable to use and can prevent red buttocks.

[0031] During production, on the diaper production equipment, unwind the concave-convex hot-air non-woven fabric described in Example 1 and combine it with the lower non-woven fabric, the flow guide layer, the composite core, the side leakage barrier and the anti-seepage bottom film After compounding, dry and comfortable diapers are obtained. In the diaper of this patent, firstly, the multiple hydrophilic low-melting two-component fiber is made into the multiple hydrophilic hot-air non-woven fabric, and the ...

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...
