Para-aramid filament

The full name of para-aramid is poly (p-phenylene terephthalamide), which is a kind of aromatic polyamide fiber. The English name is poly-p-phenylene terephthamide, referred to as PPTA, and our country is also called aramid-II or aramid 1414. It is a linear macromolecule composed of amide groups connected to each other in the para-benzene ring, wherein at least 85% of the amide bonds are directly connected between the para-benzene rings.
