Terylene air-jet textured yarn fabric with high color fastness

Abstract

The present invention relates to a terylene air-jet textured yarn fabric with high color fastness and belongs to the technical field of textile. In order to solve a problem of poor color fastness of a fabric in the existing technology, the invention provides terylene air-jet textured yarn fabric with high color fastness. The fabric is mainly weaved from terylene air-jet textured yarn, wherein the terylene air-jet textured yarn is mainly prepared from raw materials of terephthalic acid, glycol monomer, hexamethyldisiloxane, tellurium dioxide, colouring agent, titanium nitride, toner, promoter, dispersant and stabilizer, and the raw materials can also be added with fire retardant or antioxidant. The invention has advantages of high color fastness, uniform coloring and good brightness, and reaches washing resisting color fastness of grade 4-5 , sweat resisting color fastness of grade 4-5 and light resisting color fastness of higher than grade 7; and the raw materials of the invention do not need dyeing after spinning to realize the reduction of environmental pollution, reduction of high temperature dyeing process, and improvement of the strength property of the yarn.

Description

technical field [0001] The invention relates to a fabric, in particular to a polyester space-changing yarn fabric with high color fastness, which belongs to the technical field of textiles. Background technique [0002] As one of the three main fibers in synthetic fibers, polyester is widely used in clothing fabrics and other non-clothing fields because of its excellent physical and chemical properties. Polyester air-converted yarn uses special processing technology to make polyester yarn have the feel and soft touch of natural cotton yarn, and at the same time overcomes the wrinkle resistance of cotton. It is washable and easy to care. Decorative fabrics, curtain fabrics and fashion fabrics, etc.). Because polypropylene fiber has the characteristics of low density, good warmth retention and wear resistance, low moisture regain and good moisture conductivity. Therefore, polypropylene is widely used in the textile field. However, polypropylene fiber, a hydrocarbon polymer, ...

AI Technical Summary

Problems solved by technology

The polyester air-converted yarn obtained by the above method has the advantages of smooth yarn surface after dyeing, less burr and high production efficiency, and is widely used. Structural characteristics, under hot and humid conditions, the binding force on the movement of macromolecular segments is small, and the macromolecules in the non-crystalline part of the high orientation are prone to disorientation, resulting in high irregular shrinkage of the cheese at high temperature, and the shrinkage rate can reach 15% to 25%. After entering the dyeing process, the uneven yarn density of the inner and outer layers of the cheese will cause uneven penetration of the dye solution during dyeing, resulting in color spots and uneven dyeing during the dyeing process. The dyeing process has low color fastness to polyester air-variable yarn after dyeing, so that the polyester air-variable yarn fabric made of this material is easy to fade during use and has a low service life.
