Methods to improve the cohesive beam nature of an aramid yarn bundle and reduce its coefficient of friction and to knit, sew, or interweave aramid yarn bundles and knitted tubes for automotive applications

摘要

METHODS FOR IMPROVING THE COHESIVE NATURE OF BEAM BEAM STRIPS AND REDUCE YOUR COFFICIENT COFFICIENT AND FOR KNITTING, SEWING, OR KNITTING YARN STRAPS FOR AUTOMATIC APPLICATIONS. The invention pertains to a method for improving the cohesive nature of an aramid yarn bundle and reducing its coefficient of friction, composed of the addition to the yarn bundle of 0.1 - 3.0 wt%, based on the weight of the aramid yarn. yarn, a water-soluble dispersible film-forming binder, followed by treating the yarn bundle with an oil having an intrinsic viscosity of less than 100 mm² / s.
