Imported PP polypropylene filament non-woven fabric is a kind of non-woven fabric.
To put it simply: it is not intertwined and knitted together by yarns one by one, but the fibers are directly bonded together through physical or chemical methods. Therefore, when you get your clothes When the stick inside is weighed, you will find that you cannot pull out the threads one by one.
The polypropylene in the imported PP polypropylene filament non-woven fabric is a polymer formed by the addition polymerization reaction of propylene.
It is a white waxy material with a transparent and light appearance.
The density is 0.89~0.91g/cm3, it is flammable, the melting point is 165℃, it softens at about 155℃, and the use temperature range is -30~140℃[2]??.
It can withstand the corrosion of acid, alkali, salt liquid and various organic solvents below 80℃, and can decompose under high temperature and oxidation.
Polypropylene is widely used in the production of clothing, blankets and other fiber products, medical equipment, automobiles, bicycles, parts, transportation pipelines, chemical containers, etc., and is also used in food and pharmaceutical packaging.
Suzhou ptfe filter membrane manufacturer supplies imported PP polypropylene filament non-woven fabric, which has high strength, small vertical and horizontal strength difference, aging resistance, melting point at 164~170℃, and the product can be sterilized at temperatures above 100℃ .
