Problems solved by technology

[0003] Composite non-woven fabrics are made by compounding non-woven fabrics and other fabrics in various ways, and compounding two or three layers of fabrics through composite treatment to produce products with special functions. In most of the application fields of cloth, especially in the field of medical hygiene and clothing, there are high requirements for the moisture-proof and breathable properties of non-woven fabrics, but in the prior art, in order to achieve this effect, materials often need to have Good moisture absorption performance, absorbing water vapor to achieve moisture-proof effect. Although this solution can take into account the moisture-proof and breathable performance of the material, it cannot maintain this performance for a long time. After absorbing a certain amount of water vapor, the non-woven fabric has a moisture-proof effect It is easy to breed bacteria when the non-woven fabric itself is in a humid situation for a long time; Curing and bonding together, but due to process problems, it is easy to cause agglomeration of the composite non-woven layout part. How to improve the moisture-proof and breathable effect of the non-woven fabric, improve its effective moisture-proof time and the touch of the non-woven fabric is currently a problem that needs to be solved. problems, in order to address these problems, the present invention provides the following technical solutions

Abstract

The invention discloses a damp-proof and breathable composite non-woven fabric and a preparation method thereof. The damp-proof and breathable composite non-woven fabric comprises a skin-friendly layer, a middle layer and a damp-proof and breathable bottom layer, wherein the two surfaces of the middle layer are respectively bonded with the skin-friendly layer and the damp-proof and breathable bottom layer by hot-melting adhesive layers. The damp-proof and breathable composite non-woven fabric and the preparation method disclosed by the invention have the beneficial effects that the three-layerstructures are arranged, the hydrophobic treatment is carried out on the damp-proof bottom layer, the hydrophilic treatment is carried out on the middle layer, a large part of water vapor is isolatedby the damp-proof bottom layer, the water vapor is absorbed by the middle layer, so that the non-woven fabric has good damp-proof and breathable functions; a bonding tooling is arranged to adhere thethree-layer structures of the composite non-woven fabric simultaneously, the temperature is rapidly reduced by a cold environment, so that molten hot-melting fibers are prevented from being bonded into pieces; the prepared composite non-woven fabric is good in handfeel, and no influence is caused on the damp-proof and breathable properties of the composite non-woven fabric.

Description

technical field [0001] The invention belongs to the technical field of textile fabrics, and in particular relates to a moisture-proof and breathable composite non-woven fabric and a preparation method thereof. Background technique [0002] Non-woven fabric, also known as non-woven fabric, is composed of directional or random fibers. It is called cloth because of its appearance and some properties of cloth. With many advantages such as recycling and simple processing, it is now widely used in many fields such as medical care, decoration, and clothing. [0003] Composite non-woven fabrics are made by compounding non-woven fabrics and other fabrics in various ways, and compounding two or three layers of fabrics through composite treatment to produce products with special functions. In most of the application fields of cloth, especially in the field of medical hygiene and clothing, there are high requirements for the moisture-proof and breathable performance of non-woven fabric...
