what is sewing thread

Sewing thread is a thread necessary for knit products and is classified into three types: natural fiber, synthetic fiber and blended spinning. With the development of the polyester industry, more and more polyester fibers are used as sewing materials for sewing threads.

Polyester is also called high-strength thread, nylon sewing thread is nylon thread, also known as (beadlite). Made of polyester long or short fibers, it has excellent abrasion resistance, low shrinkage and chemical stability. However, it has a low melting point, melts at a high speed, clogs needle holes, easily breaks threads, has high strength, is excellent in abrasion resistance, has a low shrinkage rate, is excellent in hygroscopicity and heat resistance, and therefore corrodes. It is strong against mold and mildew, and does not stick to insects. Widely used for sewing cotton, synthetic fiber and blended fabrics. In addition, it also has the features of perfect color, good color fastness, no fading, no color change, and resistance to sunlight.

Difference between polyester sewing thread and nylon sewing thread: Polyester ignites lumps, black smoke, does not have a heavy odor, does not stretch, nylon sewing threads also ignite, lint, white smoke, stretchy odor Increasingly heavy. High abrasion resistance, excellent light resistance, mildew resistance, coloring around 100 degrees, low temperature dyeing. Widely used because it has high seam strength, durability and flat seams, and can meet a wide range of needs for industrial sewing products.
