[Common textile manual] nylon sewing thread

Overview

That is, nylon sewing thread. A sewing thread made from nylon 6 or nylon 66 filaments. The abrasion resistance and dry strength of nylon yarns are among the highest in chemical fiber category, the wet strength is lower than that of polypropylene, the elongation rate is 20%~35%, alkali resistance and acid resistance, flexibility resistance, and loop strength are high. , And corrosion-resistant, almost free from the influence of microorganisms, will not mold and insects. The disadvantage is poor heat resistance, not suitable for high-speed sewing, poor lightfastness, yellowing after long-term sun exposure, and decreased strength.

Variety

The raw material of the nylon sewing thread is nylon 6 or nylon 66 filaments, which are monofilament, multifilament and textured yarn. The corresponding nylon monofilament yarns, multifilament yarns and elastic yarns are produced accordingly. Nylon sewing thread is smooth, silky and elastic. Nylon 6 sewing thread has high strength and wear resistance. It can be used for sewing shoes and leather. Nylon 66 sewing thread melting point higher than nylon 6, heat-resistant approximate polyester, can be used for work clothes, knitted outerwear, suit trousers sewing. The elasticity of the deformation elastic nylon sewing thread can be used for sewing elastic fabrics such as knitted underwear and stockings.
