Abstract

The invention discloses a making method of an ultraviolet-proof cotton fabric. The method comprises the steps that firstly, chitosan is modified for preparing a modified chitosan dispersion solution,then zinc oxide is modified for preparing a modified zinc oxide dispersion solution, a cotton fabric is pretreated, subjected to padding in the modified chitosan dispersion solution for 30-50 min, roasted and then subjected to padding in the modified zinc oxide dispersion solution for 30-50 min, and circulation padding is conducted one or more times. The made cotton fabric has a good ultraviolet-proof effect and is durable, good in washing resistance, simple in process, capable of easily achieving industrialization and suitable for application and popularization.

Description

technical field [0001] The invention belongs to the technical field of functional fabrics, and in particular relates to a preparation method of an anti-ultraviolet cotton fabric. Background technique [0002] With the continuous progress and development of society, people's cognitive level is also constantly improving, and they pay more and more attention to their own safety. The protection of clothing, which is the first priority in "basic clothing, housing and transportation", is also more and more valued. As we all know, the intensity of ultraviolet radiation is the strongest throughout the year, especially in summer. In the hot summer, if the skin is exposed to strong sunlight for a long time, it will be sunburned by ultraviolet rays. Short-term exposure will promote the increase of melanin synthesis. It can lead to hyperpigmentation, such as dark spots, freckles, chloasma, etc., which will increase, increase, and darken, affecting the appearance of the skin. If it i...
