Production method and application of mesh type full cotton semi-defatted spunlace non-woven fabric

By combining semi-degreasing and hydroentangling processes, a 22-mesh structure of all-cotton nonwoven fabric is formed, which solves the balance problem between hydrophilicity, softness and mechanical properties of all-cotton hydroentangled nonwoven fabric, making it suitable for high-end medical and health products.

AI Technical Summary

Technical Problem

Existing cotton spunlace nonwoven fabric production technology struggles to maintain fiber softness and mechanical properties while improving hydrophilicity and liquid absorption capacity, and traditional perforation methods easily lead to structural inhomogeneity and reduced mechanical strength.

Method used

Using mild chemical and heat treatment methods, the natural oils and pectin on the surface of cotton fibers are partially removed through a semi-degreasing process, and a 22-mesh mesh structure is formed by hydroentangling, which preserves the softness of the fibers and improves their hydrophilicity and whiteness.

Benefits of technology

This nonwoven mesh fabric, made of semi-degreased cotton, achieves high hydrophilicity, whiteness, and a soft feel. It is suitable for high-end medical and hygiene products and has excellent air and liquid permeability as well as good mechanical properties.

Abstract

The present application relates to the technical field of non-woven fabric production, and particularly discloses a production method and application of a mesh type full-cotton semi-degreasing spunlace non-woven fabric, which comprises the following steps: 1) first, raw materials are opened, mixed and carded into a uniform fiber web through a carding process, and then subjected to spunlace treatment to obtain a pure cotton gray fabric with a 22-mesh type; 2) the pure cotton gray fabric obtained in step 1 is subjected to pretreatment in a scouring and bleaching process, and then treated through a semi-degreasing process to produce a mesh type full-cotton semi-degreasing spunlace non-woven fabric gray fabric. The method provided by the present application partially removes natural grease (cotton wax), pectin and other accompanying substances on the surface of cotton fibers through a mild chemical and heat treatment method, rather than completely removing them, so that the hydrophilicity, whiteness and compatibility with functional components in the subsequent process of the cotton fibers are significantly improved while the natural soft touch of the cotton fibers is retained.
