High-strength polyester fiber composite yarn is generally used in industrial fields such as automobile tire lines, light box cloth, conveyor belts, fire belts, etc. The single-filament breaking strength of general civilian fibers is less than 5cN / dtex. At present, the polyester single-filament strength of about 5Cn / dtex available on the market is mainly used for fabric products such as headscarves, masks, and gap cloths.
