Seamless bras made of elastic fiber and acetate have become fashionable with simple plain cups worn with outerwear. Acetate fiber is a high-grade fiber that meets consumers’ strict requirements for textiles.
5． Soybean protein fiber: Soybean meal, which in the past could only be used for feeding and fertilizer, can now be used for spinning and weaving. Soy protein fiber, known as “artificial cashmere”, is currently the only fiber material independently developed by my country and the first in the world to achieve successful industrialization trials. Soybean protein fiber is a fiber formed by extracting plant protein from soybean meal. It is a renewable plant protein fiber. Soybean protein fiber not only has the characteristics of fine monofilament, light specific gravity, high strength and elongation, good acid and alkali resistance, but also has cashmere-like feel and warmth. New fabrics made of pure soybean fiber or blended and interwoven with wool, silk, cotton, linen, polyester and other fibers. It has good luster, drape and wrinkle resistance. It is ideal for making high-end underwear, cashmere sweaters, high-end casual clothing and suits. Ideal material for , sportswear and home textiles.
6. Bamboo fiber: Bamboo fiber is bamboo pulp fiber, which is a regenerative plant fiber. Bamboo fiber fabric has good hygroscopicity and moisture release, smooth hand feel, drape type, resilience, abrasion resistance, good dyeability, bright luster, and UV resistance, but its disadvantage is low wet strength. Usually used to produce handkerchiefs, mats, bedding, carpets, decorative items, daily antibacterial towels, bath towels and other varieties.
7. Corn fiber: Polylactic acid fiber, which is made from lactic acid formed by fermentation of corn starch, is considered one of the most promising degradable polymers today. The characteristics of corn fiber include excellent skin contact, drape and softness; good elasticity and not easily affected by ultraviolet rays; anti-pilling, easy to dye, non-flammable, and good hydrophilicity; the raw materials come from plants and are biologically easy to Decomposes, has no environmental pollution problems, and the resources are renewable. Its products are widely used in knitting, weaving and weaving, especially suitable for infant and young children’s intimate clothing.
8. Pupa protein fiber: Pupa protein fiber is chemically extracted silkworm pupa protein and processed using polymer modification technology, chemical fiber spinning technology, and bioengineering technology. It is rich in 18 kinds of amino acids and has noble properties.��It feels comfortable, healthy and safe, can effectively promote metabolism, prevent skin aging, and has anti-itching and anti-sun radiation effects. It is superior to silk in terms of dyeability, drapeability, wrinkle resistance and resilience, giving textiles the feel and style of silk. Pupa protein silk is used to make high-end clothing fabrics, T-shirts, underwear, bedding, etc.
9. Chitin fiber: Chitin is widely found in the shells of insects and aquatic crustaceans and in the cell walls of fungi and algae. It is an extremely abundant natural polymer and renewable resource second only to cellulose. Women’s sanitary napkins, baby diapers and other women’s and children’s products, bedding and toiletries.
10． Milk velvet: Milk velvet is made from milk by skimming, dehydrating, extracting protein and velvety polymer, and spinning it into milk velvet fiber through wet spinning process and special management. Its softness and skin-friendliness are equal to or better than cashmere; it has good breathability and moisture conductivity; its warmth retention is close to that of cashmere; its wear resistance, anti-pilling properties and strength are all better than cashmere; the amino acids contained in milk protein have a protective effect on the skin. , and the price is only 1/10 of cashmere; milk cashmere can be spun purely or substituted for cashmere and blended with other types of fibers to form a velvety style fabric.
02 New natural textile materials
1. Colored cotton fiber: Natural colored cotton is a new type of cotton cultivated by high-tech means such as biogenetic engineering, that is, genes of different colors are inserted into cotton plants, so that the cotton has different colors. The use of colored cotton for spinning, weaving and fabrics does not require bleaching, printing and dyeing. It has the characteristics of unique style, simple and elegant colors. After repeated use and washing, its color is still as beautiful as before. More importantly, there is no three waste emissions and no environment Pollution will not affect human health or cause skin disorders, etc. It represents the direction of the development of ecological textiles in the three links of production, processing and use, truly achieving “zero pollution” in the entire process from fiber growth to finished products. Colored cotton is particularly suitable for making various underwear, infant products and bedding that are in direct contact with the skin.
2． Colorful silk: With the advancement of technology, white silkworms can now spin colorful silk. This is mainly due to the mutant gene of silkworms, which can avoid the dyeing process and the color is pure and natural, which is in line with today’s trend of returning to nature.
3. Colored sheep wool: Colored sheep wool has appeared in the world in recent years. Scientists feed sheep certain metal trace elements to change the color of the wool. If iron is fed, sheep wool can turn light red. Colorful wool sheep in bright red, sky blue, golden yellow and brown colors have been bred.
4． Colored rabbit fur: In recent years, an environmentally friendly new member of the rabbit breed has appeared – colored rabbits. Countries with more developed rabbit breeding industries have successively raised this colorful rabbit that everyone loves. There are many varieties of colorful rabbits in the United States. There are certain quantities and varieties in our country.
5. Optim fiber: Optim fiber is developed by using wool physical modification technology to adjust the internal structure of wool fibers. Its technical principle is to use physical principles to draw and stretch ordinary wool under specific conditions, thereby reducing the fiber fineness by 3 microns. In this way, the fineness of the processed wool will reach or even exceed that of cashmere, and its length can be 3 to 4 times that of cashmere, becoming a brand-new new fiber with cashmere characteristics. With the increasing living standards of consumers, the demand for cashmere in domestic and foreign markets is increasing. However, cashmere goats have obvious destructive effects on vegetation and the ecological environment. They cannot be raised in large quantities, and cashmere resources are difficult to expand. The development of Optim fiber products with cashmere characteristics is in line with the utilization of wool resources, increasing the added value of wool products, and human health concepts of protecting the ecological environment. Products produced with Optim fiber have the characteristics of cashmere: thin, light and soft, smooth to the touch, bright in color, moisture absorbent and warm, high-end in style, comfortable to wear, and have excellent slipperiness, elongation, strength coefficient and other indicators. Better than cashmere.
