Abstract

The invention discloses a layer by layer self-assembling anti-flaming cotton fabric. A preparation method of the layer by layer self-assembling anti-flaming cotton fabric comprises the following steps: (1) preparing a polycation sol; (2) preparing an anion solution; (3) pre-treating the cotton fabric; (4) preparing the anti-flaming cotton fabric. The polycation sol and the anion solution adopted by the invention have a certain synergistic effect for resisting against fire; the reaction condition is mild; the process is simple; the operation is convenient; the method is green and pollution-free.

Description

technical field [0001] The invention relates to the technical field of flame-retardant cotton fabrics, in particular to a method for constructing flame-retardant coatings on the surface of cotton fabrics through layer-by-layer self-assembly. Background technique [0002] Textiles are used in all aspects of life, but according to relevant data, fires caused by textiles account for half of the world's fire accidents every year, causing huge losses to people's lives and properties. As the most widely used natural fiber, cotton fabric has the advantages of dyeability, biocompatibility, moisture absorption, breathability, warmth retention, soft hand, etc., but its limiting oxygen index is only 18%, which is easy to burn and cause fire, which seriously threatens people's health. Safety of life and property. Therefore, it is particularly important to study the flame-retardant finishing of cotton fabrics. In order to endow cotton fabrics with a certain flame-retardant performance,...
