the difference between polyester slice and polyester slice is that the composition of polyester slice is "high viscosity polyethylene terephthalate ester resin (pet)", which is generated by condensation polymerization of terephthalic acid (pta) and ethylene glycol (eg). it is called a polyester chip because it is produced by pet pelleting under water
fiber grade pet chip used in the manufacture of polyester staple fiber and polyester filament, is supply polyester fiber enterprises processing and related products of raw materials, polyester as chemical fiber production in the largest species, nearly 80% of the market, occupy the chemical fiber industry market changes and development trend of polyester series is therefore focused on chemical fiber industry.
at the same time, polyester is also used in bottle, film and other applications, widely used in packaging industry, electronic appliances, medical, health, construction, automotive and other fields, including packaging is the largest non-fiber polyester application market, but also the fastest growing pet field. it can be said that polyester chip is an important intermediate product that connects petrochemical products and products of many industries.
polyester fiber is an important synthetic fiber variety, is the name of china's polyester fiber products. it is based on refined terephthalic acid (pta) or terephthalic acid dimethyl ester (dmt) and ethylene glycol (eg) as raw materials through esterification or ester exchange and condensation polymerization of the fiber - polyethylene glycol terephthalate (pet), after spinning and post-processing of fiber. polyester is widely used in clothing and industrial products. polyester has excellent formability. polyester yarn or fabric after the formation of flat, fluffy shape or pleating, etc., in the use of many times after washing, still can remain unchanged.
