Modification method for preparing highly-hydrophilic real silk fiber spunlace non-woven material

Abstract

The invention relates to a modification method for preparing a highly-hydrophilic real silk fiber spunlace non-woven material, which comprises the following steps: soaking real silk in hydrophilic modification solution for 8 to 10 minutes, taking out the real silk, dehydrating and drying the real silk, and cutting the real silk into short fibers of 30 to 50 millimeters in length; and spraying water to prewet the real silk short fibers, controlling the moisture regain to be less than or equal to 17 percent, sealing the real silk short fibers for 24 hours and then taking out the real silk short fibers, and processing the real silk short fibers in a carding machine of which the linear velocity is between 30 and 120 meters per minute and the hydraulic pressure is between 30 and 100 bars. The highly-hydrophilic real silk fiber spunlace non-woven material prepared by the modification method has the advantages of soft texture, good gloss, no off-flavor, good moisture absorption, air permeability and no chemical additives, and belongs to green environment-friendly products.

Description

technical field

[0001] The invention belongs to the field of preparation of silk fibers, in particular to a method for modifying and preparing highly hydrophilic silk fiber spunlace nonwoven materials. Background technique

[0002] Silk is a high-grade textile raw material with good strength and elongation. The fiber is thin and soft, smooth and elastic. Its main component, silk peptide, contains 18 kinds of amino acids that are beneficial to the human body. It has strong compatibility with human skin and less irritation. (The skin irritation coefficient is only 7.4%, while that of polyester is 25.5%), known as the "fiber queen".

[0003] Silk fabric is a traditional product of our country, which has always been mainly machine-woven. Since the "Sixth Five-Year Plan", silk knitted fabrics have been developed. After more than 30 years of research and development, silk knitted fabrics have become a major category of silk products today, forming a A new industry. However, ther...
