Abstract
The objective of this paper was to explore the preparation and properties of porous polyester fully-drawn filaments(FDY)and to compare and analyse them with porous pre-oriented filaments(POY)and stretch deformed filaments(DTY)with the same composition that had been prepared by the previous group.The experi-mental findings demonstrated that after acid and alkali treatment,the FDY underwent a pore formation process in-ternally,and the optimal parameters of acid and alkali treatment process were determined to be 4%mass fraction NaOH and 3%mass fraction HCl,which were equivalent to those of the porous polyester POY and DTY.The characteristic peaks of the infrared spectra of the three types of porous filaments were consistent with the thermal decomposition temperature.The thermal decomposition curves of FDY and POY before and after acid and alkali treatment were the same,the change trends of the specific surface area of FDY and DTY were consistent with each other,and N2 adsorption amount of FDY was observed to be the highest.The fracture strengths of porous FDY and porous DTY were similar,the elongation at break of porous DTY was the highest,by contrast,the breaking strength and elongation at break of porous POY were the lowest.关键词
