Antimicrobial hydrophilic finishing technology for plasma-chitosan-based silver-loaded-nanometer titanium oxide for polyester fabric

Abstract

The invention discloses an antimicrobial hydrophilic finishing technology for plasma-chitosan-based silver-loaded-nanometer titanium oxide for a polyester fabric. The antimicrobial hydrophilic finishing technology comprises the following steps of soaking the polyester fabric into a sodium hydroxide solution, performing drying after alkali decrement handling, then putting the polyester fabric in anacetone solution sealed with a preservative film for soaking, taking out the polyester fabric, and airing the polyester fabric in a fume cupboard; putting the polyester fabric subjected to alkali decrement handling in a vacuum reaction chamber, starting a vacuum pump, regulating a vacuum degree, the output power and the treatment time in the vacuum reaction chamber, and beginning plasma treatment; uniformly mixing an organosilicone quaternary ammonium salt antimicrobial finishing agent, a hydrophilic finishing agent and chitosan silver-loaded antimicrobial coating layer solution, soaking thepolyester fabric after plasma treatment into a mixture, adopting a two-soaking and two-milling method to perform antimicrobial hydrophilic coating layer finishing, and performing drying, baking, coldwater scrubbing and airing; and putting the polyester fabric finished with chitosan compounded impregnation liquid in ultrasonically dispersed nanometer titanium oxide finishing liquid, and performingtreatment, drying, baking, washing and drying in a polyester high-temperature and high-pressure dyeing machine.

Description

technical field [0001] The invention belongs to the technical field of polyester products, and in particular relates to a plasma-chitosan-based silver-loaded nano-titanium oxide antibacterial and hydrophilic finishing process for polyester fabrics. Background technique [0002] With the development of textile science and technology, higher requirements are put forward for the comfort of clothing products for different consumer groups and use environments. Clothing products represented by cotton fibers have good hygroscopicity, but they are easy to breed bacteria when used in harsh and humid environments for a long time, which limits their use in special environments. Polyester fiber has excellent mechanical properties: high strength, good elasticity, and strong dimensional stability. It is an important variety in synthetic fibers, but its hygroscopicity is poor, it is prone to static electricity and pollutants, and it feels stuffy and comfortable when worn. Insufficiency li...

Clothing products represented by cotton fibers have good hygroscopicity, but they are easy to breed bacteria when used for a long time in harsh and humid environments, which limits their use in special environments

Polyester fiber has excellent mechanical properties: high strength, good elasticity, and strong dimensional stability. It is an important variety in synthetic fibers, but its hygroscopicity is poor, it is prone to static electricity and pollutants, and it feels stuffy and comfortable when worn. Insufficiency limits its application, so it is of certain significance to develop comfortable polyester clothing products adapted to special environments
