Definition of New Type Fiber
Because the shape, performance or other aspects are different from the original traditional fiber, it is called new type fiber. Also to adapt to the need of production and life, some fibers are improved performance. The traditional fiber no longer meets the needs of people in some aspects. So the new type fiber comes into being to solve some defects. It reflects that people increase demands for textile materials.
Categories of New Type Fiber
1.New type natural fiber
New type natural fiber includes natural colored cotton and modified wool. By chemical bleaching and dyeing process, ordinary cotton fabric become colorful. And the textiles made of natural colored cotton can have a riot of color without chemical dyeing and finishing process. It is the real green and environmentally-friendly product. At present, there are three series of colored cotton, as brown, green and taupe.
By wool deforming treatment, the diameter of wool fiber can be reduced by 0.5-1μm, the handle turns soft and exquisite, the moisture adsorption performance, abrasion performance, heat retaining property and dyeing performance, etc. are improved and the luster become shiny.
2.New type cellulose fiber
The new type cellulose fiber is hailed as the “green fiber” of the 21st century. It has soft hand feeling, good drapability, mercerized glossy, good moisture adsorption and air permeability, anti-static performance and strong wetting strength. New type cellulose fiber includes Lyocell, modal and riche, etc. Blends of new type cellulose fiber with other fibers expand day by day. They are suitable for making women’s wear and casual wear.
3.Regenerated protein fiber
The regenerated protein fiber is made by spinning and made of protein solution extracted from natural animal milk or plants.
Among, soybean protein fiber has low density monofilament, strong strength and elongation, good acid resistance and alkali resistance and soft hand feeling. It has the handle like wool, the soft luster like silk, the moisture adsorption performance, wet permeability and good wearing comfort like cotton fiber and the heat retention property like wool. But its heat resistance is poor and the fiber itself appears beige. In addition, soybean protein fiber has wide adaptability, which has good blending effect with cotton, wool, acrylic fiber, polyester and rayon, etc.
Silkworm pupa protein fiber has good moisture adsorption performance and air permeability, soft hand feeling and good drapability. But its wet strength is low and the fiber itself appears rather dark yellow color, which will influence the color and brightness of textiles.
4.Water-soluble fiber
It is a kind of fiber that can be soluble in water under certain technological condition. Mostly it is used to blend with other fibers, which can make the yarns and fabrics fluffy, the yarn count thin and the fabric soft, light and fluffy. The main products are water-soluble Vinylon, water-soluble PVA and water-soluble K-Ⅱ, etc. They are mainly used following spinning process.
The advantages are: ①Low cost ②High spinning efficiency ③Fabrics are high-grade. After blended with water-soluble fiber, the smoothness, fluffiness and THV, etc. of fabrics are improved.
5.Functional fiber
(1) It is to modify the conventional synthetic fibers, which will overcome their inherent defects.
(2) It is to endow the fibers with heat storage, electric conduction, water adsorption, moisture adsorption, antibacterial property, deodorant performance, perfume and flame-retardant performance, etc. that natural fibers and chemical fibers do not previously have by chemical and physical modification methods. It makes the fiber more comfortable for wearing and more suitable for decorative application.
(3) The third type functional fiber has special functions, as high strength, high molecular, heat resistance and flame resistance. The products include organic conductive fiber, elastic fiber, ultraviolet prevention fiber, antibacterial and deodorant fiber, anion fiber, chitin Fiber and high moisture absorbing fiber, etc.
