Problems solved by technology

[0015] To sum up, due to the difference in structure, performance and processing technology, the existing processing methods of woven fabrics and knitted fabrics with unidirectional water guide function cannot be directly applied to non-woven materials, and in order to overcome the machine with unidirectional water guide function Fabrics and knitted fabrics are not convenient for large-scale production of disposable products, and the defects of unidirectional water-conducting nonwoven materials prepared by finishing agents are complicated to process and pollute the environment, and meet the needs of materials with unidirectional water-conducting functions in different fields , it is very necessary to study low-cost, high-speed production, and environmentally friendly production methods and material structures

Abstract

The invention relates to a spunlaced non-woven material with the one-way water guide function and a preparing method and application thereof. The spunlaced non-woven material is formed by respectively carding hydrophilic fiber and hydrophobic fiber into webs, then compositing the webs, and reinforcing the webs in a spunlaced mode. According to the preparing method, the hydrophilic fiber and the hydrophobic fiber are respectively carded to obtain the hydrophilic fiber web and the hydrophobic fiber web, the hydrophilic fiber web and the hydrophobic fiber web are laid and recombined to obtain a composite fiber web, and the composite fiber web is reinforced in the spunlaced mode, stand and is dried to obtain the spunlaced non-woven material. The spunlaced non-woven material is applied to medical protecting clothes, wound accessories and diaper coating layers, the method is wide in range of processed fiber, existing production equipment can be directly used, and the production process protects the environment and is free of pollution.

Description

technical field [0001] The invention belongs to the field of water-conducting functional materials and their preparation and application, in particular to a spunlace non-woven material with a unidirectional water-conducting function and its preparation method and application. Background technique [0002] Non-woven materials are widely used in various fields of the national economy due to their wide range of raw materials, various types of processes, flexible technological changes, high production speed and low production costs. With the development of the economy and the advancement of science and technology, new nonwoven materials, new processes and new products are constantly emerging, and the application fields are constantly expanding. [0003] As one of the mechanical reinforcement processes of nonwoven materials, spunlace reinforcement has the advantages of high production speed and no environmental pollution in the production process. Most of its products are disposa...
