What are the differences and characteristics of polypropylene and spandex?
Polypropylene fiber: lightweight, is a use-product propylene as a raw material, a synthetic fiber such as petroleum refining, is also known as polypropylene fiber, also known as polypropylene fiber. It is made from propylene as a raw material, and the fibers prepared by melt spinning.
1. Features: The polypropylene fiber is a relatively light fiber in common chemical fibers. It is almost unheat, but has good core suction capacity, high strength, stable fabric size, is very good, and the chemical stability is good. However, poor thermal stability, no sunlight, easy to aging and crisp.
2, use: can be banned, mosquito net, flocculated, warm filler, diaper wet, etc. Industrial: carpet, fishing net, canvas, water dragon belt, medical belt instead of cotton gauze, hygiene products.
Spandex: elastic fiber
1. Features: Spandex has a good elasticity, poor intensity, poor absorption, good light resistance, acid, alkali resistance, and wear resistance. Spandex is a high-elastic fiber necessary for pursuit of dynamic and convenient high-performance clothing. Spandex can be elongated by 5-7 times, so it is comfortable, the hand feels soft, and does not wrinkle, can always maintain the original contour.
2, use: Spandex uses its characteristics to be widely used in underwear, women in underwear, casual wear, sportswear, socks, pantyhose, bandage, etc., medical field, etc.
Specifications of polypropylene short fibers 0.3-110dt, length 5-150mm, annual output of 30,000 tons, complete color.
Use of polypropylene short fibers:
Polypropylene short fibers are mainly used: non-woven fabrics for hygiene materials (such as women sanitary napkins, baby diapers, medical masks, hats, etc.), acupuncture carpets, electric blanket fabrics, filter cloth, geotextile, car decoration cloth , Clothing lining, artificial fur, yarn, gauze, hygiene hot-rolled non-woven fabric, polypropylene spinning, interior parts, speaker cloth, textile wire, filter material, adsorption material, cigarette filter, rope, rope, filter material Equisical fields.
