          Introduction of common chemical fiber properties

          2018-11-07 14:30:44

          1、 Viscose (hygroscopic  easy to dye):

          It is a kind of man-made cellulose fiber, which is spun by solution method. Because the solidification rate of the core layer  the outer layer of the fiber is  the same, the skin core structure is formed (as can be seen  the cross section sections). Viscose is a common chemical fiber with strong moisture absorption, good dyeability, good wearing comfort, poor elasticity of viscose, poor strength  wear resistance in wet state. Therefore, viscose is  resistant to water washing  has poor dimensional stability. The ratio is great, the fabric is heavy, alkali resistant  acid resistant.

          Viscose fiber is widely used in almost all types of textiles, such as filament lining, beautiful silk, flags, streamers, tire cords, etc.; short fiber for cotton, wool, blending, weaving, etc

          2、 Polyester (crisp  wrinkle free):

          Features: high strength, good impact resistance, heat resistance, corrosion resistance, moth resistance, acid  alkali resistance, good optical rotation resistance (next to acrylic fiber), 1000 hours of exposure, 60-70% strength, poor moisture absorption, difficult dyeing, easy to wash  dry, good shape retention. It has the characteristics of "washable  wearable"


          Filament: it is often used as low elastic filament to make all kinds of textiles;

          Staple fiber: cotton, wool, hemp, etc. can be blended. In industry: tire cord, fishing net, rope, filter cloth, edge material, etc. At present, the amount of chemical fiber is large.

          3、 Nylon (durable):

          The big advantage is strong  wear-resistant, which is one of the best. Low density, light fabric, good elasticity, resistance to fatigue damage, good chemical stability, alkali  acid resistance

          The major disadvantage is that the sun resistance is  good, the fabric will turn yellow after long time of sun exposure, the strength will decline,  the moisture absorption is  good, but it is better than acrylic fiber  polyester fiber.

          Uses: long silk, mostly used in knitting  silk industry; short fiber, mostly blended with wool  wool type chemical fiber, used for gabardine, vanillin, etc. Industry: cord  fishing net, also used as carpet, rope, conveyor belt, screen, etc

          4、 Acrylic (bulky  sun resistant):

          The performance of acrylic fiber is very similar to wool, so it is called "synthetic wool".

          Molecular structure: acrylic fiber is very unique in internal large-scale structure, with irregular spiral conformation  no strict crystallization area, but it has high order arrangement  low order arrangement. Because of this structure, acrylic fiber has a good thermal elasticity (processable expanded yarn), the density of acrylic fiber is smaller than wool,  the fabric has a good thermal insulation.

          Features: good sunlight  climate resistance, poor moisture absorption  difficult dyeing.

          Pure acrylonitrile fiber, due to its tight internal structure  poor wearing performance, can improve its performance by adding the second  third monomers. The second monomers can improve its elasticity  handle,  the third monomers can improve its dyeing performance.

          Uses: mainly used for civil use, can be pure  blended,  can be made into a variety of wool, wool, blankets, sportswear: artificial fur, plush, expanded yarn, water hose, Parasol Cloth, etc.

          5、 Vinylon (water soluble moisture absorption):

          It is characterized by high hygroscopicity  good synthetic fiber, so it is called "synthetic cotton". Its strength is worse than that of nylon  polyester,  its chemical stability is better,  it is  resistant to strong acid  alkali. It also has good resistance to sunlight  climate, but it has poor elasticity to dry heat but  to damp heat (shrinkage). The fabric is easy to wrinkle, poor in dyeing   bright in color.

          Uses: blended with cotton: fine cloth, poplin, corduroy, underwear, canvas, waterproof cloth, packing materials, labor clothes, etc.

          6、 Polypropylene (light  warm):

          Polypropylene fiber is a light fiber in common chemical fibers. It is almost non hygroscopic, but it has good wicking capacity, high strength, stable size, good wear resistance  elasticity,  good chemical stability. But: poor thermal stability,  resistant to the sun, easy to aging brittle.

          Application: it can knit socks, mosquito nets, quilts, warm padding, wet diapers, etc. Industry: carpet, fishing net, canvas, water hose, medical belt instead of cotton gauze, do sanitary products.

          7、 Spandex (elastane):

          Good elasticity, poor strength, poor moisture absorption, good light resistance, acid resistance, alkali resistance  wear resistance.
