对位型全芳香族共聚酰胺拉伸纤维及其制造方法
Abstract:
拉伸弹性模量为630cN/dtex以上的对位型全芳香族共聚酰胺拉伸纤维。对于对位型全芳香族共聚酰胺原料纤维，在特定范围的张力和温度下实施高张力热拉伸而得到。
Abstract(English):

Provided is a para-type wholly aromatic copolyamide drawn fiber of which the tensile modulus of elasticity is 630 cN/dtex or higher. The drawn fiber is obtained by carrying out high-tension thermal drawing of a para-type wholly aromatic copolyamide fiber raw material within a specified tension and temperature range.
