Polyphenylene sulfide fiber, also known as PPS fiber. It is prepared from polyphenylene sulfide by melt spinning. Phillips company of the United States industrialized in 1983, with the trade name of Ryton PPS fiber. The polymer is prepared by polycondensation of sodium sulfide and dichlorobenzene in N-methylpyrrolidone or organic polar solvent containing alkali metal carboxylate. The melting point is 285 ℃. Amber, strength 0.18 ~ 0.26n/tex, elongation 25% ~ 35%, initial modulus 2.65 ~ 3.53n/tex. With good heat resistance, it is mainly used as high-temperature filter fabric, and the withstand temperature can reach 190 ℃. The fiber also has excellent chemical reagent resistance, hydrolysis resistance and flame retardancy. It can be used as flame retardant fabric, home decoration fabric, flue gas filter material, etc.
PPS fiber not only plays an outstanding role in the field of filtration, its monofilament or multifilament fabric can also be used as demisting material, paper machine drying cloth, sewing thread, various protective cloth, electrical insulation material, heat-resistant clothing material and other materials; In addition, PPS fiber can be used to make long fiber reinforced composites for military industry, aerospace and other fields. PPS fiber fabric is treated with a mixture of fluorine gas, oxygen and nitrogen, which is especially suitable for isolation material of electrochemical energy storage device.
