Abstract
This invention relates to a novel microfiber, to a nonwoven web comprising said microfiber, and to a method of preparing said web. The meltblown microfibers have a diameter of less than 150 micrometers. The microfibers are prepared by meltblowing a liquid crystal polymer such as a wholly aromatic polyester amide of p, p' biphenol, p-hydroxybenzoic acid and terephthalic acid or a wholly aromatic polyester amide of 2-hydroxynaphthoic acid, p-aminophenol and terephthalic acid.
