Entangled methods for producing polyolefin multifilament and entangled polyolefin-based multifilament filter cloth and

摘要

PROBLEM TO BE SOLVED: To provide a method for producing polyolefin based multifilament without crimp obtained by a weaving process, suitable for raw material of filter cloth, effectively obtained without using fiber finishing oil.;SOLUTION: The method for producing entangled polyolefin based multifilament comprises a process imparting a low temperature evaporating liquid to the polyolefin based multifilament, heating and drawing the multifilament by a drawing roller with temperature set at the temperature below the boiling point of the low temperature evaporating liquid and then a process entangling.;COPYRIGHT: (C)2006,JPO&NCIPI
