Introduction of the common synthetic fiber
2013/12/27 Viewers:
Common synthetic fibers mainly refers to the traditional six acrylic fiber , namely polyester, nylon, acrylic, polypropylene , polyvinyl alcohol , and polyvinyl chloride fibers.
In order for the production of polyester > PP > Nylon > Acrylic .
1 . Polyester
Polyester is a polyester fiber China trade name . PET from terephthalic acid or dimethyl terephthalate and polyethylene glycol produced by polycondensation terephthalate obtained , is the largest generic synthetic , ranking first in all of its production of chemical fibers . By melt spinning polyester with a series of excellent properties, such as high fracture strength and elastic modulus, moderate elasticity, excellent heat-setting properties, high heat resistance , light resistance is acceptable .
2 . Nylon
Nylon is a polyamide fiber of our trade names, is a linear structure of the polymer amide bond with a number of methylene connected together (- - CONH). In 1935 , DuPont was first synthesized a polyamide fibers ( nylon 66 ) , and industrial production began in 1938 . In the same year , the German chemist P. Schlack made of nylon 6 , and industrial production in 1941.
Nylon has a series of excellent performance, textile fibers ranks highest wear resistance , high breaking strength, stretch big , resilience and excellent fatigue resistance , moisture behind PVA in synthetic fibers , synthetic fibers in the case of dyeing preferred.
3 . Acrylic
Acrylic fibers are polyacrylonitrile Chinese trade name, which is more than 85% of acrylonitrile and other second , third monomer copolymerized polymer spun synthetic fibers. 1953 by DuPont first to achieve commercialization of acrylic .
Acrylic has many excellent properties, such as soft , flexible, and there are "synthetic wool ," said. Resistant to sunlight and weather resistance are particularly good, dyeing is better, so more land for knitted fabrics and sweaters.
4 . Polypropylene
Polypropylene is isotactic polypropylene fibers China trade name . 1955 successfully developed in 1957 by the Italian industrial production began . Polypropylene is more variety, there are filament , staple fiber, film split fibers, bristles and flat wire and so on.
Polypropylene particularly light texture , density is only 0.91g/CM3, is the lightest of all synthetic fibers . High strength polypropylene , and has good chemical resistance, but polypropylene heat resistance, light resistance, poor dyeing .
5. PVA
PVA also known Vinylon , polyvinyl alcohol fibers China trade name . Untreated polyvinyl alcohol fibers soluble in water , sulfuric acid or titanium, with formaldehyde acetals of the heat treatment can improve the water resistance. Narrow sense refers specifically polyvinyl alcohol PVA after formal treatment formal fibers. PVA 1940 put into industrial production .
PVA is relatively good moisture absorption , has been called " synthetic cotton ," said. PVA chemical stability , corrosion resistance and light resistance , strong alkali resistance . PVA long on the sea or in the soil are difficult to degrade , but the poor performance of PVA heat water , less flexible , dyeing performance is poor, dark color , easy to pilling, pilling .
6. Polyvinyl chloride
Polyvinyl chloride polyvinyl chloride fibers China trade name . PVC successful research in 1931 , 1946 and put into industrial production in Germany .
Polyvinyl chloride and cotton close to the intensity , abrasion resistance , thermal resistance, sunlight than cotton, wool is good. Good polyvinyl chloride resistant inorganic chemical reagent stability , acid and alkali resistance , corrosion resistance strong , sound good , but the stability and dyeing properties of organic solvents are relatively poor.
