What are man-made fibers? What are his strengths and weaknesses?
The new representatives of man-made fibers are new fabrics, such as light burned mercerized cotton, silk, Khmer and so on. These materials are soft, comfortable, and do not shrink, and they are highly flexible and extremely smooth. Although it has become the designer's preferred fabric, but the disadvantage is that its price is not as good as nylon, but can not be fully promoted.
Synthetic fibers are often used as underwear materials and are popular because of their comfort and proximity. Lycra and cotton is the underwear industry leader in materials. Cotton not only eliminates the stained part, make underwear more environmentally friendly, but also retain the cotton soft and comfortable, very suitable for the production of underwear.In addition, nylon is another representative product of man-made fibers. Nylon is our commonly known as nylon, it has the elasticity, acid and alkali corrosion, not easy to mildew, strong wear-resistant features, but also makes nylon became the first choice of factory work clothes. But it also has some shortcomings, nylon obvious lack is not sweat absorption, comfort is relatively poor; and long drying, yellowing, aging; long wear will pilling.
Synthetic fiber has similar properties as natural fibers. It has good moisture absorption, air permeability and dyeing properties. It is soft and lustrous. It is an important textile material. It can be spun or blended with natural fibers such as wool and silk and synthetic fibers. Viscose fiber in the high strength because of high strength, good resistance to many times deformation, can be used in industry. Regenerated protein fiber having a property similar to wool and used as a substitute for wool. Proteins can be grafted, copolymerized or blended with other fibers to improve the properties of other fibers. In 1984, man-made fiber production was about 3.1Mt, accounting for 21.3% of total chemical fiber output.
One of the two major types of chemical fibers. Some natural polymers or their derivatives are used as raw materials, and then they are made into textile solutions. Then they are spun into fibers. Bamboo, wood, bagasse, cottonseed and so on are all raw materials for making man-made fibers. According to the shape and use of artificial fiber, it is divided into three kinds: rayon, artificial cotton and synthetic wool. Important varieties are viscose fiber, acetate fiber, copper ammonia fiber and so on.
