In the chemical fiber, many lay people can not tell the polypropylene and polyester. What is the difference between them? Today, the national star Xiaobian hands to teach you how to distinguish between polypropylene and polyester?
Please enter the title abcdefg

First small stars first tell you about polypropylene and polyester.

Polypropylene is the commercial name of polypropylene fiber, it is made of propylene as raw materials by polymerization, melt spinning fiber. Polypropylene in 1957 officially began to industrial production, synthetic fiber is a rising star. As polypropylene has a simple production process, low cost, high strength, the relative density of light, so the rapid development of polypropylene. At present, polypropylene is the fourth largest variety of synthetic fibers.

Polyester is an important species in synthetic fibers, is China's polyester fiber trade name. It is based on pure terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (EG) as raw materials by esterification or ester exchange and polycondensation reaction prepared by the fiber polymer - - polyethylene terephthalate (PET), fibers made by spinning and post-treatment.

What is the difference between the two? In this little star to teach you a simple way
Combustion identification method

Polyester: When the fiber shrinks, burning, side of the smoke, the flame was yellow, with a slight sweet, burning left dark brown lumps.

Polypropylene: side curled, one side of the melting burning, bright flame, blue, slightly like asphalt smell, after burning ashes into a light brown.

In addition, polypropylene is lighter than water, floating on the water; polyester than water, sink in the water.
