Abstract

The invention relates to a preparation method of a heat-resistant sewing thread, and belongs to the technical field of spinning. The method comprises the following steps of preparing an oxidized polyethylene wax micro-emulsion by adopting a high-pressure emulsification method to serve as a softening agent, adding the micro-emulsion into polyether ether ketone resin, preparing polyether ether ketone fibers by melt spinning, twisting the polyether ether ketone fibers and polytetrafluoroethylene fibers to form a blank thread, soaking the blank thread in a polyphenylene sulfide resin melt, and performing curing to obtain a sewing thread material with good heat resistance and wear resistance. The capability of forming a film by the oxidized polyethylene wax micro-emulsion is good, the frictioncoefficient of the fiber surface can be remarkably reduced, the melting point is high, the micro-emulsion can be used as the softening agent of the high-speed sewing thread, the flexibility is high, and the warp breaking probability of yarns is greatly reduced; and the fabric stress condition can be changed by improving slippage of the yarns in a fabric.

Description

Technical field [0001] The invention relates to a method for preparing a heat-resistant sewing thread, and belongs to the technical field of textiles. Background technique [0002] Sewing thread is the thread needed for knitted clothing products. It is made by twisting two or more single yarns or single filaments. There are also a few of them are knitted. It is stronger, even, smoother and richer than yarn. It is elastic, and is often specially finished to have the characteristics of passing through the eye of the needle and suitable for the wear resistance when sewing clothes. Sewing thread is a material that consumes a lot of clothing accessories. Its physical and chemical properties and product quality directly affect the quality level of the finished product's production, wearability and appearance. Its performance is also directly related to the sewing industry. The labor productivity is an indispensable product in people’s lives. [0003] Sewing thread refers to the thread ...
