The Application Of New Fiber Materials In Weft Knitted Products Is In Line With The Trend Of The Trend.

Comfort, functionalization, fashion, environmental protection and diversification are taken. Knitted products The development trend. Knitting Yarn enterprise In the warp knitting, weft knitting and sweater enterprises, new varieties of raw materials are continuously emerging to provide strong support for the development of weft knitted products. The development trend of weft knitted products and the application of new fiber materials in weft knitted products are reviewed in this paper.

The development direction of China's knitted products during the "12th Five-Year" period is to develop new technologies, such as new type knitting, ultra-thin and ultra-fine fabric knitted processing, and promote the development of new differentiated and functional chemical fiber knitted products. Weft knitted products are developing towards high machine circular knitting machine, seamless underwear and computerized flat knitting machine. The application of new fiber materials in weft knitted products is in line with this background. The following are the introduction of new fiber materials and new cellulose fibers and yarns that can be applied to weft knitted products.

The new fiber materials are hollow cotton yarn, hollow cotton yarn developed in Japan, and the yarn has a core structure. When the core of the yarn is dissolved, it becomes hollow, resulting in hollow effect. The hollow cotton yarns developed in China are blended with cotton and vinylon. This kind of product has the characteristics of light weight, soft handle, quick water absorption and good thermal insulation. It can be used to develop knitted sweaters, knitted underwear, casual wear and other products. Super low twist cotton yarn has almost no twist, so it has a cashmere like super soft handle and is mainly used for knitted fabrics. It can produce knitted sweater, casual wear, and Terry knitted products such as bath towel, bathrobe, pajamas and so on. Cotton and wool core spun yarn (LUNAFA), the yarn has a skin core structure. The yarn core is wool (10%), and the outer cotton is wrapped (90%). It has the comprehensive properties of wool fiber elasticity, warmth retention, soft touch and comfortable wearing of cotton fiber, and can avoid the prickle feeling of the pure wool knitted underwear. This yarn can be used to develop knitted underwear, knitted sweater and other products. The wool is refined, and the protein macromolecules are rearranged through the stretching and shaping of ordinary wool, so that the wool fiber becomes thinner and longer. A new type of cotton with special color of cotton fiber in the process of bolting is selected from natural colored cotton by modern biotechnology. At present, brown, green, red, yellow, gray, purple and other colors can be used. Knitted underwear Socks and other knitted products.

In addition, there are new cellulose fibers and yarns and weft knitted products: Modal fiber, developed by the Austria Lenzing Co (Lenzing), the high wet modulus cellulose regenerated fiber, which is made from European beech, first made into wood pulp, then spinning into fiber. The product is soft, comfortable, silk like luster, slippery, moisture absorption and breathability. It is suitable for knitted underwear, jacket, sportswear and home textiles. At present, Modal fiber has developed products with new functions, such as Modal antibacterial fiber, Modal anti ultraviolet, color Modal fiber and ultrafine Modal fiber. Tencel fiber, developed by ACORDIS, UK, is currently a green fiber produced by Lenzing Co. The raw material comes from natural wood, and is made into wood pulp. The NMMO spinning process is used to dissolve wood pulp in direct spinning with ammonium hydroxide solvent, and ammonium hydroxide is recycled, and the recovery rate is over 99%. The product has high dry and wet strength, high swelling property and unique fibrillar characteristics, and has good spinnability. It can be blended with various natural fibers, cellulose fibers and functional fibers, and is suitable for wool knitting, underwear, T-shirt, socks, leisure products, etc. Sheng Ma fiber is extracted from natural hemp by means of cooking, bleaching, making, spinning, post processing and so on. The cellulose extracted from the hemp material is preserved, and the natural antibacterial substance in the hemp material is retained. The characteristics of this fiber are: the cross section is plum blossom and star shaped, irregular, hygroscopicity and permeability, natural bacteriostasis and mildew resistance, and even dyeing. It is suitable for knitted underwear, decoration and bedding. There are two kinds of bamboo fiber, bamboo fiber and bamboo fiber. The cellulose content of the original bamboo fiber is over 60%. It is made from the processing technology of soaking, boiling, softening and bleaching. The fiber is characterized by its slubby surface, fabric cool, moisture absorption, breathability, antibacterial and lustre. Bamboo fiber has the characteristics of antibacterial, breathable, draping, moisture absorption, abrasion resistance, good dyeing, Hikaruzawa Ryorei and so on. Currently, bamboo fiber used in market mainly refers to bamboo fiber, which can be applied to knitted underwear and socks. Richcel (lissai) fibre It is a registered trade name of Polynosic, a kind of plant cellulose fiber made from Japan's Oriental textile proprietary technology and production system. It is also known as modified viscose fiber in China. Fiber characteristics: high wet modulus, high breaking strength, small elongation at break, low water absorption and alkali resistance. Product features: wet, breathable, soft, smooth, draping, bright and shiny, suitable for making knitted underwear, sweater, T-shirt, etc.
