Large Comparison Of Man-Made Fibres

　　 1. Viscose (moisture absorption and dyeability).

yes Man-made fiber Plain fibers are prepared by solution spinning. The core structure is formed from the cross section section due to the inconsistency between the fiber core layer and the solidification rate of the outer layer. Viscose is the most absorbent fiber in ordinary chemical fiber. It has good dyeing property, good wearing comfort, poor elasticity of viscose, poor strength and wear resistance under wet condition. Therefore, viscose is not resistant to water washing, and its dimensional stability is poor. The fabric is heavy, alkali resistant and acid proof.

Viscose fibers are widely used, and almost all types of textiles are used, such as filament lining, beautiful silk, flags, ribbon, tire cord and so on. Staple fibers are Imitation cotton, wool like, blended, interwoven, etc.

　　 Two, polyester (crisp and wrinkled)

Features: high strength, good impact resistance, heat resistance, decay resistance, resistance to bores, acid and alkali resistance, good light resistance (second only to acrylic), 1000 hours of exposure, strong retention of 60-70%, poor moisture absorption, dyed fabric, easy washing, quick drying and good shape retention. Features of "washable and wearable"

Purpose:

Filament: often used as low elastic wire, making various kinds of textiles.

Staple fiber: cotton, wool, hemp and so on can be blended, in industry: tire cord, fishing net, rope, filter cloth, edge material and so on. It is the largest amount used in chemical fiber at present.

Three, nylon (solid and wear-resistant)

The biggest advantage is that it is tough and durable. Small density, light fabric, good elasticity, fatigue resistance, good chemical stability, alkali resistance and acid resistance.

The biggest drawback is that the resistance to sunlight is not good. The fabric will turn yellow after long exposure, and the strength will decrease, and the moisture absorption will not be good, but it will be better than acrylic and polyester.

Purpose: filament, used for knitting. Silk industry Staple fibres, mostly blended with wool or wool type chemical fibers, are made of WordArt, van nedin and so on. Industry: cord and fishing nets, carpet, ropes, conveyor belts, screens, etc.

Four, acrylic fiber (bulky and light resistant)

Acrylic fiber is very similar to wool, so it is called synthetic wool.

Molecular structure: acrylic fiber is very unique in internal macro structure, showing irregular spiral conformation, and there is no strict crystalline region, but there are high order and low order arrangement. Because of this structure, acrylic fiber has good thermal elasticity (processable bulky yarn), and its acrylic fiber is small in density, smaller than wool, and the fabric has good thermal insulation property.

Characteristics: good sunlight resistance and good weather resistance (ranking first), poor moisture absorption and difficult dyeing. Pure acrylonitrile fiber, because of its tight internal structure and poor wearing performance, improves its performance by adding second and third monomers. The second monomer is improved: elasticity and handle, and third monomer improves dyeability.

Usage: mainly for civilian use, it can be pure spinning or blended. It is made of many kinds of wool, wool, blankets and sportswear. It can also be made of artificial fur, plush, bulky yarn, hose, Parasol Cloth and so on.

Five, vinylon (water soluble moisture)

The biggest characteristic is hygroscopicity, the best in synthetic fiber, known as "synthetic cotton". Its strength is better than that of nylon and polyester, its chemical stability is good, it is not strong acid and alkali resistant. Sun resistance and weather resistance are also good, but it is resistant to dry heat and moisture resistance (shrinkage) elasticity is the worst, fabric wrinkles, poor dyeing, color is not bright. Uses: cotton and cotton blend: fine cloth, poplin, corduroy, underwear, canvas, waterproof cloth, packaging material, labor clothes, etc.

Six, polypropylene (light weight and warmth)

Polypropylene fiber is the lightest fiber in common chemical fibers. It has almost no moisture absorption, but has good wicking ability, high strength, stable fabric size, good abrasion resistance and good chemical stability. However, it has poor thermal stability, no sun resistance and easy ageing and brittle damage. Application: it can knit socks, mosquito net cloth, quilt, warm stuffing, diaper wet and so on. Industry: carpet, fishing net, canvas, water hose, medical instead of cotton gauze, sanitary products.

Seven, spandex (elastic fiber)

The elasticity is the best, the strength is the worst, the moisture absorption is poor, and it has better light resistance, acid resistance, alkali resistance and abrasion resistance.

Purpose: spandex is widely used in underwear, such as underwear, casual wear, sportswear, socks, pantyhose, bandage and so on. Spandex is the pursuit of movement and convenience. High performance fabrics The necessary high elastic fibers. Spandex is 5-7 times longer than its original shape, so it is comfortable, soft, and wrinkle free.
