Abstract: PURPOSE:To obtain the title novel fiber good in mechanical properties, extremely high in chemical resistance, also high in heat resistance and low in shrinkage by specifying tenacity, Young's modulus and strength retention rate after sulfuric acid immersion. CONSTITUTION:The objective fiber >=4.6g/de in tenacity. >=60g/de in Young's modulus and >=60% in strength retention rate after immersion in 98% sulfuric acid at room temperature. It is preferable that this fiber be obtained by the following process: undrawn yarn prepared by melt spinning of an aromatic sulfide polymer is drawn by a factor of at least its natural draw ratio under heating to 80-120 deg.C, and the resultant semi-drawn yarn is further drawn at 150-260 deg.C so that the total draw ratio fall between 1 and 1.5 times the draw ratio at the first stage.
