The needle sewing thread also contains high strength sewing thread. High-strength needle sewing thread, also known as pearlescent needle sewing thread, is also widely used in garment or footwear industry.

High-strength needle sewing thread, also known as tedo and polyester needle thread, is twisted by continuous high-strength and low-elongation polyester filament. It has high temperature resistance of 130 degrees, high tensile force, low elongation and no elasticity. 

However, it has poor wear resistance and is harder than nylon needle thread. It burns black smoke and dyes at 130 degrees high temperature.

High strength needle sewing yarn thread is made of high strength polyester filament, so its yarn properties are high, knotless and uniform. At the same time, high strength needle sewing yarn thread has good properties such as high strength, good wear resistance, corrosion resistance, mildew resistance, jointless and so on. It is also stable for different strength changes and reduces the breakage and replacement of needle sewing yarn thread.  

The products of needle thread produced by this project are widely used in sewing shoes, professional clothing, professional equipment, leather furniture, leather jewelry and special military supplies.

High-strength needle yarn thread is suitable for sewing various garment materials and has dual functions of practicality and decoration. 

According to the raw materials, it can be divided into three categories: natural fiber high strength needle thread, synthetic fiber needle sewing thread and mixed needle sewing thread.

1. Natural fiber high strength needle thread

Cotton high strength needle yarn thread - Needle sewing thread made from cotton fibers through refining, bleaching, sizing and waxing. Cotton high strength needle yarn thread can also be divided into light-free (or soft), silk and wax light. 

Cotton high strength needle yarn thread has high strength and good heat resistance. It is suitable for high speed sewing and durable pressing. It is mainly used for sewing cotton fabrics, leather and high temperature ironing clothes, but its disadvantages are poor elasticity and wear resistance.

Silk needle yarn thread - Filament or silk needle yarn thread made of natural silk, has excellent gloss, and its strength, elasticity and wear resistance are superior to cotton needle yarn thread. Suitable for sewing all kinds of silk clothing, high-grade woolen clothing, fur and leather clothing, etc.

2. High strength synthetic fiber needle thread

High-strength polyester needle yarn thread - Made of polyester filament or staple fibers, has high strength, good elasticity, wear resistance, low shrinkage and good chemical stability. 

However, due to its low melting point, easy melting at high speed, blocking needle eyes and breaking needle thread, attention should be paid to the selection of machine needles. 

Mainly used for jeans, sportswear, leather products, wool and military uniforms, is the most widely used high-strength needle thread.

Nylon high strength needle yarn thread - Made of pure nylon polyfilament, divided into filament needle yarn thread, staple needle yarn thread and elastic deformation needle yarn thread. 

At present, filament needle yarn thread is commonly used. 

It has large elongation and good elasticity, and its tensile length at breaking moment is three times longer than that of cotton needle yarn thread of the same specification. 

It is used for sewing chemical fibers, wool, leather and elastic clothing. 

The greatest advantage of nylon needle sewing thread is transparency. Because of its transparency and good color, it reduces the difficulty of sewing wiring and has broad prospects for development. 

However, in the current market, the stiffness and strength of transparent needle yarns threads are too large, and the stitches are easy to float on the surface of fabrics. In addition, the stitching speed can not be too high because of the high temperature resistance. 

At present, this kind of needle thread is mainly used for applique, cutting edge and other parts which are not easy to bear force.

Vinylon high strength needle yarn thread- Vinylon fiber, high strength, smooth stitching, mainly used for sewing thick canvas, furniture cloth, labor insurance supplies.

Acrylic high-strength needle yarn thread- Made of acrylic fibers with low twist and bright dyeing. It is mainly used for decoration and embroidery. 

3. Mixed high strength needle thread

Polyester-Cotton high strength needle yarn thread - Made of 65% polyester and 35% cotton. It has the advantages of both polyester and cotton. It has high strength, wear resistance, heat resistance and shrinkage. It is mainly used for high-speed sewing of all kinds of clothing, such as cotton, polyester and cotton.

Core-wrapped high-strength needle yarn thread - Filament as core, wrapped with natural fibers, strength depends on the core needle yarn thread, wear resistance and heat resistance depends on the wrapped needle yarn thread, mainly for high-speed and solid garment sewing.

High-strength needle yarn thread is suitable for sewing various garment materials and has dual functions of practicality and decoration. 

The quality of high strength affects not only the sewing effect and processing cost, but also the appearance quality of finished products. 

In the prescribed conditions, the ability of high strength needle thread to form good stitches while maintaining certain mechanical properties, called seamability, is a comprehensive index for evaluating the quality of stitching. According to the material, thickness, organization, color, sewing style, sewing equipment or means, the sewing thread and machine needle matching the types and specifications can be selected. Generally, the following principles can be followed:

1. Coordination of needle thread with fabric properties

It can ensure the unity of shrinkage rate, heat resistance, wear resistance and durability, and avoid the shrinkage caused by too large difference between lines and fabrics. In general, fine thread is used for soft and thin materials, small size machine needle is used for hard and thick materials, and large size machine needle is used for hard and thick materials. A kind of

2. Coordination of needle thread with sewing equipment

Level sewing machine chooses left-turn sewing thread, twisting when sewing, to maintain the strength of the sewing thread. A kind of

3. Coordination of needle thread with the form of trace

Bag (bandage) sewing machine uses fine cotton thread, which is not easy to deform and wrinkle, and makes chain stitches beautiful and comfortable. Double stitches should be made with good extensibility. The crotch seam and shoulder seam should be stitched firmly. The wearable suture should be chosen for button eyeliner.

4. Coordination of needle thread with garment types

For special purpose clothing, such as elastic clothing, elastic nylon yarn is needed, and fire fighting clothing is made of high-strength heat-resistant, flame-retardant and water-proof yarn.

The production process of needle sewing thread can be divided into two kinds: continuous long fiber and short fiber. Long fibre needle sewing thread: 1. Continuous composite monofilament containing F (hole) number is made by slicing, drawing, setting and winding; 

2. Natural white strand embryo needle yarn thread made of composite monofilament through initial twisting and double twisting strands; 

3. Dyeing and smoothing treatment in dyeing and finishing workshop; 

4. Needle sewing yarn is made by separate winding. 

Short fibre needle sewing yarn thread: 

1. slicing and drawing into cotton-like staple fibers; 

2. Winding into roving and further drawing into needle yarn thread through clear flowers; 

3. Needle yarn thread embryo yarn thread of white needle sewing yarn thread with required fineness by spinning result twisting process; 

4. Color matching dyeing and post-treatment in dyeing workshop; 

5. Drying and sub-assembling and moulding. product needle thread.

The selection of needle sewing thread plays an important role in garment production. 

In order to make the sewing machine work smoothly, it is very important to select sewing thread reasonably. 

Good sewing must have three basic qualities: stitchability, durability and appearance. 

The performance of suturing finger stitches in sewing operation. That is to say, the seam is sewed on the specified material with the highest seam speed under normal operation conditions. It can be sewn into uniform and consistent stitches. 

Durability refers to the stress characteristics of needle sewing thread in sewing operation and its durability in sewing. 

It can withstand collision, heat resistance and abrasion during sewing, endurance under constant washing and drying, and whether it can withstand various special agents or chemical tests in various processes. 

The durability of sewing means its enduring flexibility and strength. 

Appearance refers to the appearance of the needle sewing thread before sewing, especially after sewing. 

Coordination effect on fabric, neat needle thread and color harmony.
