<p>PROBLEM TO BE SOLVED: To provide a poly para-phenylene terephthalamide fiber excellent in fiber separation and capable of suppressing generation of fluff or yarn breakage in the fiber separation process.SOLUTION: The poly para-phenylene terephthalamide fiber excellent in fiber separation has 5-100 of filaments formed of a single yarn having a single yarn fineness of 3.5-10 dtex and has a degree of entanglement of more than 1 and 5 or less. An ultra fine poly para-phenylene terephthalamide fiber is formed by separating the poly para-phenylene terephthalamide fiber and has a total fineness of 3.5-150 dtex.</p> |
