High temperature resistant sewing thread and method of making.

摘要

A synthetic sewing thread of multifilament construction is described which has ability to lessen the buildup of heat at the needle of a high speed sewing machine during the operation thereof. The thread is of substantially uniform cross section throughout and devoid of alternating thick and thin areas to provide a smooth more uniform sewing thread. It comprises a plurality of texturized continuous synthetic filaments, the filaments having a non-linear crimped configuration providing bulk to the thread and being entangled with one another along the length of the thread by being directed through a fluid jet under a relatively high pressure of at least 5.6kg/sq cm and being further bound together by twisting. The thread has a heat protective lubricant coating applied thereto and penetrating the filament bundle.
