MICROPOROUS FIBRES HAVING A DENIER OF NOT MORE THAN 50, A ELONGATION BREAK OF NOT LESS THAN 30% AND A BREAK STRENGTH OF NOT LESS THAN 200 MPA

摘要

A porous fiber (54) includes a distinctive configuration of voids (52) therein to achieve advantageous levels of wettability, liquid penetration and mechanical properties. The fiber has a denier of not more than about 50, and a percent elongation at break of not less than about 30 %. The fiber can also have a tensile strength at break of not less than about 200 MPa.
