Abstract
In accordance with the invention there is provided a synthetic sewing thread of multifilament construction characterized by its ability to lessen the buildup of heat at the needle of a high speed sewing machine during the operation thereof, even during the sewing of relatively heavy weight fabrics, so as to allow the thread to be utilized as a substitute for the sewing threads conventionally required in high temperature sewing applications, such as cotton spun yarns or cotton sheathed core yarns. The thread is of substantially uniform cross section throughout, devoid of alternating thick and thin areas to provide a smooth more uniform sewing thread. The thread comprises a plurality of texturized continuous synthetic filaments, the filaments having a nonlinear 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 80 p.s.i. and being further bound together by twist. The thread has a heat protective lubricant coating applied thereto and penetrating the filament bundle.
