JapanSewing thread is divided into sewing thread, embroidery thread, industrial thread, etc. according to purpose, and the common classification is divided according to raw materials: natural fiber sewing thread, synthetic fiber sewing thread and mixed sewing thread.
Synthetic fiber sewing thread
1. Polyester staple fiber sewing thread: It is made of 100% polyurethane polyester staple fiber, which has high strength, good elasticity, abrasion resistance, low shrinkage rate and good chemical stability. There are wool on the surface, temperature resistance 130 degrees, high temperature dyeing.
Polyester raw material is the most resistant to friction, dry cleaning, stone washing, bleaching and other detergents among all materials. It has low elongation and low stretch rate, and has the characteristics of flexibility, conformability, full color, and good color fastness. , To ensure excellent seamability, and to prevent wrinkles and skip stitches. It is mainly used for industrial sewing of denim, sportswear, leather products, wool and military uniforms. It is currently the most used and popular sewing thread.
The staple fiber sewing thread is usually expressed in the way of [yarn count/number of strands], for example: 20S/2, 20S/3, 20S/4, 30S/3, 30S/2, 40S/2, 40S/3, 50S /2, 50S/3 60S/2, 60S/3, etc.

2. Polyester filament high-strength thread: using high-strength and low-elongation polyester filament (100% polyester chemical fiber) as raw material, it has high strength, bright color, smooth, acid and alkali resistance, wear resistance, corrosion resistance, high oil rate, etc. Features, but poor abrasion resistance, harder than nylon thread, burning will emit black smoke.
Long sewing threads often use the method of [Daniel/number of strands] to express the thickness specifications, such as: 150D/2, 210D/3, 250D/4, 300D/3, 420D/2, 630D/2, 840D/3, etc.; Japan, Hong Kong, Taiwan and other countries and regions usually use numbers such as 60#, 40#, 30# to indicate thickness. Generally, the larger the numerical table, the thinner the line, the lower the strength.

Generally, the larger the numerical table, the thinner the line, the lower the strength.
3. Nylon sewing thread: It is made of pure nylon multifilament, divided into filament thread, short fiber thread and elastic deformation thread. It is made of continuous filament nylon fiber twisted. It is characterized by smoothness, softness, elongation rate of 20%---35%, good elasticity, and white smoke from burning. High abrasion resistance, good light resistance, mildew proof, coloring degree around 100 degrees, low temperature dyeing. It is widely used because of its high seam strength, durability, flat seam, and can meet the needs of a wide range of different sewing industrial products. The disadvantage of nylon sewing thread is that the stiffness is too large, the strength is too low, the stitches are easy to float on the surface of the fabric, and it is not resistant to high temperatures, and the sewing speed cannot be too high. At present, this type of thread is mainly used for decals, skewers and other parts that are not susceptible to force.
Nylon thread is also called nylon thread, divided into nylon 6 (Nylon 6) and nylon 66 (Nylon 66).

4. Vinylon sewing thread: It is made of vinylon fiber with high strength and stable stitch. It is mainly used to sew thick canvas, furniture cloth, labor protection products, etc.
5. Acrylic sewing thread: It is made of acrylic fiber with low twist and bright dyeing. It is mainly used for decoration and embroidery.
Natural fiber sewing thread
1. Cotton sewing thread: a sewing thread made from natural cotton fiber through refining, bleaching, sizing and waxing. Cotton sewing thread can be divided into non-light (or soft thread), silk light and wax light. Cotton sewing 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. The disadvantage is that it has poor elasticity and wear resistance.
2. Silk thread: The filament thread or spun silk thread made of natural silk has excellent luster, and its strength, elasticity and wear resistance are better than cotton thread. Suitable for sewing all kinds of silk garments, high-end woolen garments, fur and leather garments, etc.
Mixed fiber sewing thread
1. Polyester-cotton sewing thread: It is made of 65% polyester and 35% cotton blending. 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 and polyester cotton. High-speed sewing of all kinds of clothing.
2. Core-spun sewing 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.
3. Cotton-coated polyester sewing thread: It is made of high-performance polyester filament and cotton, spun by a special cotton spinning process, with filament-like evenness, smoothness, low hairiness, small expansion, and cotton characteristics.
4. Polyester-coated polyester sewing thread: It is made of high-performance polyester filament and polyester staple fiber, spun by a special cotton spinning process, with filament-like evenness, smoothness, less hairiness, and small stretch, which is better than that of the same specification. Polyester sewing thread.
5. Rubber band line: It is also a rubber product, but it is relatively thin. It is often interwoven with cotton yarn and viscose silk to form an elastic band. Mainly used for shaping underwear, socks, cuffs, etc.
