High Strength Sewing Thread

Nylon filament sewing thread is made of continuous filament nylon fiber. It is smooth and soft. The elongation is 20%--35%. It has good elasticity and high abrasion resistance. It is widely used in sewing industrial products.

 Polyester filament sewing thread features: high strength, wear-resistant, shiny, good color fastness. The shortcomings are hard and inelastic.

A comprehensive indicator for assessing the quality of sewing threads is seamability.

High Strength Sewing Thread

The seamability means the ability of the sewing thread to smoothly sew and form a good stitch under specified conditions and maintain a certain mechanical property in the stitch.

The pros and cons of seamability will have a direct impact on product productivity, sewing quality and performance.

According to Chinese national standards, the grade of sewing thread is divided into first-class products, second-class products and other foreign products. In order to make the sewing thread have the best seamability in garment processing, the sewing effect is satisfactory, and it is very important to select and apply the sewing thread correctly.

The parameters that define the superior seamability of the sewing thread are:

High Strength Sewing Thread

High-speed sewing is not damaged

Consistent stitch formation

No skipped stitches

Uniformity to prevent tension changes during sewing

High level of wear resistance

Sufficient surface smoothness for easy access to machine guides

How to achieve the above quality requirements?

High Strength Sewing Thread

Raw yarn

The quality of the sewing thread is the key to the quality of the sewing thread, because if the original yarn is defective, it is difficult to improve the quality of the dyeing and winding process. Yarn knots, defects, hairiness and strength will have a major impact on the quality of the sewing thread and are a key factor influencing the thread breakage.


In the dry dyeing and drying process, we must not only consider the color matching and color fastness, but also the dyed yarn spindle shape, which will affect the quality of the rewinding of the wire. Since the proper yarn mandrel shape reduces the breakage rate during rewinding.


High Strength Sewing Thread

A good tapered shape is very important for unwinding during sewing. The sewing thread will break during high-speed sewing, partly because the cone unwinding tension does not match, causing the unwinding to be too fast or too slow. If the relaxation is too slow, the thread will be broken. When the thread is too fast, it will block us. Will cause the thread to break.


For sewing threads, lubricating the sewing thread is an important process. We have the most advanced in the world

High-speed winding machine with oil filling device and single-axis heating function to melt wax more evenly. This allows the yarn to be completely covered by the lubricant and achieve a more uniform oil rate.
