Ordinary Viscose Fiber
The raw material of viscose fiber is “wood”. It is the cellulose fiber obtained by extracting from natural wood cellulose and then remodeling fiber molecule.
Viscose fiber has excellent performance of moisture adsorption and easy dyeing. But its modulus and strength is poor, especially its wet strength is low.
Modal Fiber
Modal fiber is the trade name of high-wet-modulus viscose fiber. Modal fiber improves the disadvantages of low modulus and low strength of ordinary viscose fiber in wet state. It has high strength and modulus even in wet state. So it is called high-wet-modulus viscose fiber.
There are some different titles for this same product from different fiber manufacturers, such as Lenzing ModalTM, Polynosic, Toramomen and Newal, etc.
It has excellent moisture absorption performance. It is suitable for underwear.
Lyocell Fiber
The raw material of Lyocell fiber is natural cellulose polymer. It is an artificial cellulose fiber. It was invented by England Courtaulds and then was produced by Swiss Lenzing Company. The trade name is Tencel.
Lyocell fiber has better mechanical properties, better dimensional stability to washing (The shrinkage rate is only 2%) and higher moisture adsorption than viscose fiber. It has beautiful luster, soft handle, good drapability and good flowing performance.
Fiber Characteristics
1.Viscose Fiber
It has good moisture absorption, which meets the physiological requirements of human skin. Viscose fiber fabric is soft and smooth. It has good air permeability. It is anti-static and ultraviolet-proof, which is comfortable to wear and easy to dye. After dyeing, it has brilliant luster and good color fastness. It has good spinnability. It has lower wet modulus. But its shrinkage rate is high and it is easily deformed. After water washing, the handle will be hard and the elasticity and the wear resistance will become poor.
2.Modal Fiber
It has soft and smooth hand feeling, bright luster and good color fastness. Modal fiber fabric has particularly smooth and dry handle. Cloth surface is bright and shiny in luster. Its drapability is better than cotton, polyester and viscose fiber. It has the strength and toughness as synthetic fibers and the luster and handle as silk. Modal fiber fabric has wrinkle resistance and no-iron performance. It has better water absorption and air permeability. But its stiffness is poor.
3.Lyocell Fiber
It has much excellent performance as natural fibers and synthetic fibers. It has natural luster, smooth handle and high strength. It has minimal shrinkage. It has good moisture permeability and air permeability. It is soft, comfortable, smooth and cool. Its drapability is good. It is wear resistant and durable.
Applications
1.Viscose Fiber:
Both pure and blend spinning of short-staple viscose fiber are suitable for making underwear, outerwear and various decorative accessories. And the long-staple viscose fiber is light and thin in texture. It is not only suitable for making apparel fabric, but also the facing of quilts and decorative fabrics.
2.Modal Fiber:
Knitted fabric of modal fiber is mainly used for making underwear. It is also suitable for making sportswear, casual wear, shirts and high-grade garment fabric, etc. If it is blended with other fibers, it will improve the defect of poor stiffness of pure Modal fabric.
3.Lyocell Fiber:
It covers every field of textile, as cotton, wool, silk and flax fabric, as well as knitted fabric and woven fabric, which can be produced high-quality and high-grade product.
