Study On Quality Optimization Of Chitin Fiber Tencel Long-staple Cotton Blended Yarn

Polysaccharide chitin fibre is a new type of biological polymer fiber,it has high crystallinity,high elongation,good wet gas absorption features.Chitin fiber also has biological activity,biodegradable,polluting the environment etc.is a kind of green environmental protection fiber.Because chitin has a strong hygroscopicity,chitin textile production jerseys not only has good antibacterial property and wearing comfortable,not hot and sticky feeling.Chitin fibers processed into various functional products,such as health care knitted underwear,not sticky towel,health care infant clothing,antibacterial sportswear,anti-bacterial and odor-proofing bedding,bacteriostatic medical nurse.Can also be processed into all kinds of aid supplies,such as bandages,gauze,first aid kit,etc.Chitin fiber textiles with soft kind,no stimulation,high moisture,heat preservation,antibacterial deodorant function,has very good curing effect to skin,And of the health care function on atopic dermatitis,and accord with standard of green textiles and other advantages,In the 21st century is a new generation of health textiles.The current domestic production of chitin,chitosan fiber has good spinnability.But compared with cotton fiber,chitin fiber linear density is big,low intensity,to a certain extent,affected the chitin fiber yarn strength.Thicker,low strength,chitin fiber and the fiber positively charged molecules,within the same charges repel each other,the fiber in yarn article can't very good hug and together,bring certain difficulty spinning.With chitosan fibers under general conditions,we still have some difficulties in pure spinning,usually adopt chitin fiber and cotton fiber or other fibre blended to improve its spinnability.Development of fabrics feel smooth crisp,good wet gas absorption and antibacterial deodorization function.In addition,Chitin fiber due to hygroscopicity good,excellent dyeing properties.Fabric after many washing can still keeps bright colour and lustre,the market is very popular at home and abroad.In this paper,through the process test to improve the quality carding process.drawingv process and spinning process.Through the comparison of quality index,optimizing the best craft.Effectively improve the yarn quality,Mainly for spinning yarn evenness and nep,Reducing the pressure on after weaving way,Significantly improve the quality of cloth.
