In recent years, the situation of textile industry has changed dramatically, and the pace of industrial restructuring, transformation and upgrading has been accelerated. Many new types of fibre fabrics have become the darling of the market. Everyone is pursuing differentiation to increase market interest rate, and functional textiles are the most distinctive and value-added direction. Xiaobian has found several new types of fibre textiles and processing methods, hoping to give you some reference.
Coolmax fabric
1. Properties of Coolmax Fabric

Coolmax functional fabrics are made from DuPont's Dacron fibers. Dacron fiber is a hollow polyester fiber. Its cross section shape is unique, it has four tubular shape, and the tube wall of the fiber is breathable, thus forming a good-looking capillary network in the fabric. It is precisely because of the unique physical structure of this kind of fiber that it has the characteristics of moisture absorption, sweat excretion and air permeability. The fabric can discharge sweat from the skin at any time, transmit it to the surface of the fabric, and evaporate rapidly, so that the skin can be kept dry and comfortable. Coolmax functional fabrics made of Dacron fibers have the properties of moisture absorption, air permeability and perspiration, bringing a new change to clothing.
Coolmax functional fiber fabrics are twice as dry as cotton. Therefore, Coolmax fabrics for sportswear can keep skin dry and comfortable to wear.
2. Dyeing and finishing of Coolmax fabric

Process flow: turning seam & rarr; singeing & rarr; desizing & rarr; bleaching & rarr; setting & rarr; Dyeing & rarr; finishing
Technological characteristics: According to the properties of Coolmax fibers, after repeated research, test and production, it is considered that the dyeing process of Coolmax fabrics has the following characteristics:
(1) Coolmax fabric can not be treated with strong alkali, otherwise it will lead to rapid degradation of fibers, affecting many of its properties.
(2) The setting temperature of fabrics should not be too high, generally controlled at 185-190 C.
(3) The dyeing temperature should be controlled at 120 C, not too high. Excessive high dyeing temperature will cause the deformation, expansion and distortion of the porous channels in the fiber structure. After cooling, the shape of the porous channels will be fixed and the porous channels will be blocked, which will affect the moisture permeability of the fabric.
(4) In order to ensure Coolmax's moisture absorption and sweat absorption, hydrophilic softener must be used for finishing.
New elastic fabric
1. Brief introduction of PTT, PBT and T-400 fibers

PTT fiber (polypropylene terephthalate) is a new product in the family of polyester fibers, which has the characteristics of both polyester fibers and polyphenolamine fibers. In addition to its strong stain resistance, its dyeing performance is superior to nylon, soft handle and elongation are equivalent to elastic fibers. It can be dyed and printed with commonly used disperse dyes without special chemicals. The fabric has the characteristics of dry and crisp.
PBT fiber (polybutylene terephthalate) is a new type of polyester fiber. PBT fiber not only has excellent properties of PTT fiber, but also has good elasticity. T-400 fiber is a new type of composite polyester fiber which DuPont Company has recently introduced to the market. The fibers are made of two kinds of polyester fibers which are spinned side by side. Because the shrinkage of the two kinds of polyester fibers is different, the fibers can produce permanent three-dimensional crimp, which makes the fibers have excellent elasticity.
2. Dyeing and finishing of cotton/PTT, PBT and T-400 interwoven fabrics
Technological process: grey cloth turning seam & rarr; singeing & rarr; desizing & rarr; bleaching & rarr; mercerizing & rarr; setting & rarr; Dyeing & rarr; finishing
Processing characteristics:
(1) High temperature treatment (such as desizing and scouring) with strong alkali can not be used for a long time in order to avoid damaging the elasticity of fibers. Enzymatic desizing-cold heap process has better treatment effect.
(2) Mercerizing of PTT, PBT, T-400 and cotton interwoven fabrics is beneficial to improving the adsorption performance, dyeing depth and brightness of the fabrics, making the surface of the fabrics smooth and reflective uniform, and the mercerizing caustic soda concentration is 190-210 g/l.
(3) In the dyeing and finishing process, it is necessary to strengthen the washing to make the fabric fully washed.
(4) Shaping temperature should not be too high, generally controlled at 140-160 times; 30S to ensure fabric elasticity.
(5) The dyeing rate of PTT, PBT and T-400 fibers is faster, and the heating rate should be slower than that of ordinary polyester fibers in order to prevent dyeing.
(6) The dyeing temperature should be controlled at 125 C to ensure better elasticity.
Tactle fabric
1. Performance of Tactle Fabric

Tactle fiber is a high-tech polyamide 66 superfine fiber product launched by DuPont Company. The diameter of each long fiber is less than 1 dtex. Tactle fiber has special cross section and is composed of many superfine composite wires. Therefore, Tactle fabric has good water absorption and moisture permeability, and has light touch. It can be made into waterproof and moisture permeable fabric with soft handle and gorgeous appearance. After finishing with Teflon, high count and high density fabric woven with this fiber can obtain anti-fouling and waterproof. The effect.
