LIQUID-CRYSTALLINE POLYESTER MULTIFILAMENT

摘要

Provided is a liquid crystalline polyester multifilament having a fusion degree between single fibers in the range of 0 to 20. Also provided is a method of producing a liquid crystalline polyester multifilament, wherein in at least one step of a melt spinning step and a rewinding step, an anti-fusion agent is deposited on a fiber surface of a melt-spun liquid crystalline polyester multifilament from application directions different from each other by 90 to 180° in a plane perpendicular to the yarn running direction. A liquid crystalline polyester multifilament having a fusion between single fibers significantly lower than that of the prior art can be provided.
