In order to make up for the gap caused by high cost, the nylon fiber products at this stage will definitely develop towards high added value. The market development of new nylon materials, the goal should be "pursuing quality rather than production." The core technology of nylon new products is compound processing and spinning mixing technology, and through nylon special-shaped cross-section new materials, nylon microfiber and other composite materials. The nylon fabric exhibits a soft and smooth feel different from polyester, a unique fluffy feel and a natural surface feel. Improvements in the production technology of nylon processed yarns have made the variety of nylon fibers more diverse and can increase the added value of their products in order to further replace some of the polyester fiber market.
First, nylon processing technology and trends
From the point of use, global nylon fibers can be divided into three categories: clothing, industrial and home decoration. Among them, industrial use accounts for 22%, furniture use accounts for 50%, and clothing use only accounts for 28%.
Nylon fiber has excellent performance in terms of flexibility, elastic recovery and abrasion resistance, alkali resistance and acid resistance. In addition, it is the leader in human fiber products in terms of hygroscopicity and light weight. DuPont of the United States and BASF of Germany have successfully developed a new open-loop process that can simultaneously produce nylon 6 and nylon 66 chips, thereby saving one-third of the production cost, thereby reducing the price of nylon fibers and improving market competitiveness. It can be seen that the current nylon fiber products will move towards high value-added to compensate for the gap caused by the high cost.
Second, nylon imitation silkworm material
Nylon fiber has excellent elongation recovery rate, and its Young's modulus is lower than that of polyester fiber. Therefore, it has a soft and rich hand feeling and can be used as a silk-like material. It is made of nylon blended yarns with different shrinkage ratios, which are processed by different stretching and heat treatment. The fabric made of the nylon mixed fiber and the ultrafine fiber composite yarn with different shrinkage ratios has a mild luster and a soft touch after the dyeing and finishing process, since the surface of the fabric floats 0.6 denier of ultrafine fibers. Its performance is far superior to traditional nylon taffeta. This product is the “Meling†of the short-staple silk-toned nylon fabric introduced by Unitika of Japan. The Meling fabric also has high hair color and dye fastness.
Third, the new lightness material
Nylon fibers are lighter in weight, so the fabric is lighter. Ultra-lightweight fluffy fibers can be obtained by using differential hollow fiber technology or by a double cross-shaped cross section and a biaxially intersecting hollow structure. Japan's Unitika's Microart is a double-cross section with a hollow structure with two axes. Microart fiber has a hollow rate design of up to 38%. The fabric is fluffy, light and has good heat preservation. The special profiled section makes it waterproof and moisture permeable, mainly used for casual wear or spring, summer and autumn.
Fourth, new elastic composite materials
This kind of fiber is a two-component composite fiber with PU elastic fiber as the core and nylon as the sheath. It has the advantages of high PU elasticity and light weight of nylon. It will have an automatic curling effect after heat treatment, so the fabric has good fabric. Its elasticity and comfort have a luxurious natural transparent complexion effect. The main use is women's underwear, knitted socks such as pantyhose and socks, suitable for women's clothing, showing soft and generous characteristics.
Five, new functional materials
These materials include flame retardant fibers, anti-pilling fibers, anti-UV fibers, antibacterial and deodorant fibers, antistatic fibers, antifouling fibers, release-controlled aromatic fibers, high shrinkage fibers, far-infrared fibers, and the like.
