Natural color cotton referred to as colored cotton. It is a special type of cotton with a natural color of red, yellow, green, brown, gray, purple, etc. when it is bred using modern bioengineering technology. The fabrics woven from this cotton do not need to be dyed, have no chemical dye toxins, are beneficial to human health, and prevent the pollution of ordinary cotton fabrics to the environment. Because there is no need for dyeing, textile costs can also be greatly reduced. Due to these outstanding advantages, colored cotton fabrics have received special attention as soon as they come out. At present, the world is studying colored cotton from 27 countries including the United States, Peru, Australia, Israel, Pakistan, India, Turkey, and China.
China began research and development of colored cotton breeding in 1994, and colored cotton with brown, green, yellow, red and purple colors has been bred. China has become the largest colored cotton producer in the world, of which the area of ​​colored cotton in Xinjiang accounts for 97% of the country's total area.
The main characteristics of colored cotton:
1 Colored cotton fiber fabric is good for human health, affinity with skin, no irritation to the skin, in line with environmental protection and human health needs. In the pretreatment of textile dyeing and finishing, “without dyeing or bleachingâ€, the discharge of sewage is reduced, energy consumption is reduced, and no harm is caused to the environment.
2 The garments made of colored cotton fabrics are not imminently printed and dyed. The surface of cotton fiber has a layer of wax, which is usually dyed in white cotton. Chemical substances are used to eliminate wax, pectin, pulp, etc., and the color of the dye is bright, and the visual contrast is large, so it is bright. Coloured cotton is not treated with practical chemical substances in the processing process, and it still retains the characteristics of natural fibers, so that it produces a kind of visual effect.
3 Colors of colored cotton come from natural pigments, and the color changes when the color is acid and alkali. After finishing cotton fabric by natural color (e.g., water, mercerizing, singeing, etc.) will change color, but normal reaction natural colored fade characteristics, and printing products, are essentially different fade.
Modified wool
Fine wool
Wool fiber fabric is a traditional autumn and winter fabric, fluffy, warmth is good. In order to meet the requirements of wool fabrics for spring and summer clothing, in recent years, the development of wool fabrics has become lighter, thinner, and higher-grade. The fabrics need to be woven from high-count yarns, and the surface gloss of fibers also needs to be changed. However, the raw materials used in most of the light and thin wool fabrics so far are fine wools in the natural state, which are expensive and have limited production. At present, a variety of light and thin fabrics suitable for spring and summer clothing have been developed using the wool drawdown technology. Among them, the Australian Federal Institute of Industrial and Scientific Research (CSIRO) has successfully developed a wool sizing technique, which involves combing, twisting, and stretching a certain quality of tops to a stretch of 160%, and then shaping the slivers into slivers. Changing the technology can reduce the fiber diameter of 22μm 3 ~ 4μm, the length increased by 15%, the fracture strength increased by 30%, elongation decreased, fineness decreased by about 20%. Fine wool products are unique in style, combining the fine characteristics of silk and cashmere, and are high-end apparel fabrics with added value.
2. Mercerized, shrink-proof wool
Silk and anti-shrinking wool are stripped of wool flake by chemical treatment. The basic principle is to remove all or part of the flake (velvet) surface flake layer in order to obtain better performance and feel, and to make the product smooth and clean. , Cool and comfortable, no itch, can be used as a light summer shirt fabric. The mercerized fleece's anti-shrinking wool strips more and more thoroughly. The wool products produced by both types of wool can achieve anti-shrinkage and machine washable effects. The mercerized wool has a brighter, more silky luster and a smoother feel. , sense of cashmere, known as cashmere imitation cashmere.
Three fluffy silk
Silk fabrics are mostly smooth and flat, and are relatively easy to wrinkle. They often require ironing, and the practical maintenance is rather troublesome, which greatly limits the application of silk. In recent years, these silks have been determined to modify the silk, and silk silk is used to treat the silk during the silk-repelling process, so that the silk has a good bulkiness. The finished fabric has a full appearance, delicate and soft handfeel, is not easy to wrinkle and is elastic, and is suitable for making medium thick products.
Four soft linen
Due to the rough feel of hemp fabrics, and the drawbacks of itching and wrinkling, bio-enzymatic treatment methods make the hemp fibers soft and smooth, comfortable to wear, and have a certain degree of anti-wrinkle, making them more excellent summer textile fabrics. .
