A Process Study To Improve The Anti-wrinkle And Water-repellent Properties Of Wool Worsted Fabrics

Wool worsted fabrics mostly selects natural protein fiber,it has been loved by the people because of its unique flexibility and flexibility.In particular,in recent years,the rapid development of finishing technology,giving wool fabric excellent drape,hygroscopicity and warmth,as a suit and professional suit high-end fabric has been sought after,while consumer demand driven by economic conditions,worsted fabrics tend to fashion,comfort,easy care and other diversified development.This paper mainly adopts the combination of physical and chemical finishing technology and the use of environmentally friendly water repellent agent on the wool worsted fabric anti-wrinkle and water repellent finishing,discussed the different finishing process on the fabric wrinkle resistance and color effects,the best Steaming process parameters:steaming temperature 120℃,steaming time 110 s,steaming pressure 0.05 MPa,pressure roller pressure 0.35 MPa and cloth tension 1470 N,the use of polyurethane fabric anti-wrinkle finishing,analysis of the process of anti-wrinkle performance The effect of the effect.Using different water repellent finishing agent on the wool fabric for water repellent finishing,screening out the water repellent performance and environment-friendly wool worsted fabric water repellent finishing agent.The best finishing process is obtained through the finishing process:the anti-wrinkle performance of the fabric can be improved by about 1,and the color difference AE is less than 0.40.The best "rolling-baking-baking" process prescription is:finishing agent NANO-PU mass concentration 30 g/L,with liquid rate of 65%,170℃ bake for 60 s.The effects of the concentration of CP-SLA on the water-repellency of wool were the most significant,followed by the synergist XAN mass concentration,the baking temperature and the time on the wool fabric’s water-repellency effect is small.The optimum conditions of water-repellency finishing were as follows:finishing agent CP-SLA mass concentration 50 g/L,synergist XAN mass concentration 15 g/L,baking temperature 170℃ and baking time 80s.
