High Tenacity Nylon Filament Bonded Sewing Thread is a kind of sewing thread. High Tenacity Nylon Filament Bonded Sewing Thread is suitable for all kinds of clothing materials and has two functions: practical and decorative thread. High Tenacity Nylon Filament Bonded Sewing Thread has a certain tensile force, strong tensile force, gloss, high temperature resistance and other characteristics.

So how is the high-strength thread classified? According to the raw materials, it can be divided into three categories: natural fiber high-strength thread, synthetic fiber sewing thread and mixed sewing thread. Next, I will give you a detailed introduction.

1. Natural fiber high-strength thread

　　 (1) Cotton high-strength thread: a sewing thread made from cotton fiber through scouring, bleaching, sizing, and waxing. Cotton high-strength thread can be divided into no light, silk light and wax light. Cotton high-strength thread has high strength and good heat resistance, suitable for high-speed sewing and durable pressing. It is mainly used for sewing cotton fabrics, leather and high-temperature ironed clothes, but the disadvantage is that it has poor elasticity and wear resistance.

　　 (2) Silk thread: Long silk thread or spun silk thread made of natural silk, with excellent luster, and its strength, elasticity and abrasion resistance are better than cotton thread. Suitable for sewing all kinds of silk garments, high-end woolen garments, fur and leather garments, etc.

2. Synthetic fiber high-strength thread

　　(1) High Tenacity Polyester Filament Bonded Sewing Thread: Made of polyester filament or short fiber, it has high strength, good elasticity, abrasion resistance, low shrinkage and good chemical stability. However, the melting point is low, high-speed melting is easy, the needle hole is clogged, and the thread is easy to break. Pay attention to the selection of the needle. Mainly used in denim, sportswear, leather products, wool and military uniforms, etc., it is the most used and popular high-strength thread.

　　 (2) Nylon high-strength thread: made of pure nylon multifilament, divided into filament thread, short fiber thread and elastic deformation thread. Commonly used is filament thread, which has large elongation and good elasticity, and its stretched length at the moment of breaking is three times larger than that of cotton thread of the same specification. Used for sewing chemical fiber, woolen cloth, leather and elastic garments. The biggest advantage of nylon sewing thread is transparency. Because this thread is transparent and has good color, it reduces the difficulty of sewing and wiring and has a broad development prospect.

　　(3) High Tenacity Nylon Filament Bonded Sewing Thread: Made of vinylon fiber, with high strength and stable stitches, it is mainly used to sew thick canvas, furniture cloth, labor protection products, etc.

　　(4) High Tenacity Polyester Filament Hollow Sewing Thread: Made of polyester fiber, low twist, brightly dyed, mainly used for decoration and embroidery.

3. Hybrid high-strength wire

       (1) Polyester-cotton high-strength thread: It is blended with 65% polyester and 35% cotton. It has the advantages of polyester and cotton. It has high strength, wear resistance, heat resistance, and good shrinkage. It is mainly used for cotton, polyester High-speed sewing of cotton and other clothing.

　　(2) Core-spun high-strength thread: The filament is the core and is made of natural fiber outsourcing. The strength depends on the core thread. The wear resistance and heat resistance depend on the outer yarn. It is mainly used for high-speed and firm garment sewing.
