【Abstract】 p-Phenylene terephthalamid(PPTA) fiber is a fiber with high intension,high modulus and heat -resistance which was produced through liquid crystal solution,thus is the most important high-tech fiber currently.Modification of PPTA fiber through technique was simply introduced.The focus was on functional modification.The properties such as adhesivity,dyeing behaviour,and sunlight resistance were improved. The behaviours in application,softness,conductivity,antistatic property,light and heat resistance were also improved.更多还原
