Abstract

The invention relates to the technical field of textiles and especially relates to a nano-composite material used for cotton ramie fabrics and a preparation method thereof, wherein the nano-compositematerial includes, by weight, 10-30 parts of a color fixation modifier, 2-5 parts of a crosslinker, and 15-25 parts of a modified nano-photocatalyst. The nano-composite material can significantly improve the dyeing property of the cotton ramie fabrics and increase color fixation and dyeing rate. The modified nano-photocatalyst enables the cotton ramie fabrics to have a photo-catalytic sterilization and mildew-proofing function, so that problems that conventional cotton ramie fabrics are liable to be mildewed, are incompletely dyed, have low glossiness and color fastness and are liable to yellow can be solved.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a nanocomposite material used for cotton and linen fabrics and a preparation method thereof. Background technique [0002] With the significant improvement of people's living standards, more and more people pay attention to the quality of life. As textiles are important materials in daily life, people put forward more and higher requirements for textile products. In recent years, cotton and linen fabrics have become more and more popular. Many people like clothing made of cotton and linen, which are comfortable to wear and have good air permeability. Cotton and linen fabrics are also very common fabrics in the home textile market. Cotton and hemp refer to textiles made of cotton and hemp as raw materials. Cotton and hemp are grown from plants in temperate zones. The seeds of cotton and hemp are harvested, dried in the sun, and machine-threshed to decompose the seeds and cotton ...
