Problems solved by technology

[0004] The key technology of textile multifunctional finishing is the preparation and application process of finishing agents; the existing finishing methods have certain effects, but there are many deficiencies. This is because it is difficult for chemical finishing agents to react with fibers, and chemical finishing agents only cover Adding a cross-linking agent to the surface of the fiber can improve the bonding fastness between the chemical finishing agent and the fiber and improve certain performance, but it will cause the decline of the breathable and moisture-permeable function of the textile, which will bring about a decline in the added value of the textile.

Abstract

The invention discloses a preparation method of a multifunctional textile. The preparation method of the multifunctional textile comprises the following steps: firstly preparing a blocked low temperature crosslinking agent by taking xylylene diisocynate (XDI), polyethylene glycol, an initiating agent and a blocking agent as raw materials, then fully dispersing the low temperature crosslinking agent with nano silica sol and a dispersing agent polyvinyl pyrrolidone under ultrasonic conditions to obtain a low temperature crosslinking type nano silica sol compound, then modifying the low temperature crosslinking type nano silica sol compound by utilizing a flame retardant, and finally finishing a textile by adopting modified multifunctional sol to give a concave-convex structure similar to the surface of a lotus leaf to the textile, so that the textile has super-hydrophobic property and also has flame retardance, breathability and moisture permeable function.

Description

technical field [0001] The invention relates to a finishing technology of textiles, in particular to a preparation method of multifunctional textiles. Background technique [0002] At present, multifunctional textiles such as waterproof and flame retardant have been widely used in clothing fabrics, household fabrics (umbrella fabrics, tents, kitchen fabrics, dining table fabrics, decorative fabrics), industrial fabrics, labor protection fabrics and military fabrics. Cloth and other fields. Among the many waterproof finishes, the application of fluorine-containing finishing agents has the best effect, and the EU regulations on perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (ammonium) (PFOA) restrict the sale and use of fluorine-containing finishing. The application of the agent has a serious impact. Therefore, fluorine-containing finishing agents based on C6 have been developed successively at home and abroad, and have been sold in the domestic market. However,...
