Abstract
The invention discloses a method for preparing a superhydrophobic-antibacterial-ultraviolet protective polyester fiber cloth through immersion and sedimentation. The method comprises inletting nitrogen into N-hydroxymethyl acrylamide aqueous solution, increasing the temperature, then adding in swelled polyester fiber cloth and benzoyl peroxide benzene solution, stirring and refluxing the mixture for grafting reaction, extracting and washing reaction products, performing methanol extraction, and drying the extracted materials to a constant weight to obtain surface-grafted polymer-modified polyester fiber cloth; fully dissolving chitosan powder in hydrochloric acid solution, dropwise adding in sodium hydroxide solution while stirring until reaching a neutral state, then uniformly blending innanometer compound antibacterial agents, immersing the surface-grafted polymer-modified polyester fiber cloth, then filtering out surface moisture and drying the immersed surface-grafted polymer-modified polyester fiber cloth to obtain a chitosan-nanometer compound antibacterial agent-polyester fiber cloth; mixing tetrahydrofuran with hexadecyltrimethyoxysilane, then magnetically stirring in titanium dioxide nanoparticles, adding in polydimethoxysilane, hardening agent and the chitosan-nanometer compound antibacterial agent-polyester fiber cloth, and performing stirring and then drying to obtain the superhydrophobic-antibacterial-ultraviolet protective polyester fiber cloth.
Description
technical field [0001] The invention belongs to the field of clothing fibers, and in particular relates to a method for preparing superhydrophobic-antibacterial-ultraviolet protective polyester fiber cloth by a dipping deposition method. Background technique [0002] As the product with the highest output among chemical fibers, polyester has excellent properties such as high modulus, high strength, fatigue resistance, corrosion resistance, and good thermal stability. It has been applied in many fields, such as conveyor belts, automotive fibers, and filter materials. However, since polyester macromolecules contain a hydroxyl group and a carboxyl group at both ends, there are no other polar groups, so the adhesion performance of polyester is very poor. At present, the methods used to improve the adhesion properties of polyester mainly include the use of secondary dipping or multiple dipping, modification of one dipping, improvement of rubber compound formulation and polyester ...
