Weft Knitted Fabric Develops New Fibers To Create New Varieties.

< p > comfort, functionalization, fashion, environmental protection and diversification are the developing trend of knitted products.

For knitting yarn enterprises, warp knitted, weft knitted and sweater enterprises, new varieties of raw materials are constantly emerging to provide strong support for weft knitted product development.

The development trend of weft knitted products and the application of new fiber materials in weft knitted products are reviewed in this paper.

< /p >

During the period of < p > 12th Five-Year, China's < a href= "http://fz.sjfzxm.com/" > knitted product < /a > development direction: developing new technology of new type knitting, ultra-thin and ultra-fine fabric knitted processing, and promoting 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.

< p > strong > new fiber material < /strong >: hollow cotton yarn, the hollow cotton yarn developed in Japan, the yarn has a core structure, and 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 for knitted underwear, socks and other knitted products closely knitted.

< p > < a href= "http://cailiao.sjfzxm.com/Matertial/show/default.aspx" > New Fiber > /a > plain fiber and its yarn and weft knitted product: Modal fiber, developed by Austria Lenzing Co (Lenzing), high wet modulus cellulose regenerated fiber, raw material is made from beech in Europe, first made of 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.

< /p >

< p > at present, Modal fiber has developed products with new functions, such as Modal antibacterial fiber, Modal anti ultraviolet, color Modal fiber and ultra-fine 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, wet strength, high swelling and unique fibrous properties, and has good spinnability. It can be blended with various natural fibers, cellulose fibers, functional fibers, suitable for wool knit, underwear, T shirts, socks, leisure products and so on.

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 pulp fiber, which can be applied to < a href= "http://sjfzxm.com/news/index_f.asp" > knitted "/a" underwear and socks.

Richcel (Lisai) fiber is a registered brand name of plant cellulose fiber, which is produced in Japan by the proprietary technology and production system of Japanese Oriental spinning (Polynosic) (high wet modulus regenerated cellulose fiber), also known as modified viscose fiber.

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.
