The characteristics of polyester filament thread.

- Jan 11, 2018 -


The characteristics of polyester filament yarn are: high oil content, generally 4-6%, which is treated with silicone wax, which is beneficial to improve seaming.

High strength, 50% higher than polyester fiber line;

The elongation of white polyester filament is below 13%, and the elongation of dyed polyester filament is below 21%.

The polyester filament thread is similar to silk thread, which can meet the sewing requirements of leather and woolen garments.

Because the knot head is small, big package, can improve sewing efficiency.

The packaging is 10000~50000m, with no more than 1.2 per thousand meters.

A trapezoid slope is often used to prevent the filament from slipping off.

The ratio of the initial twist to the twist is usually 1, 2-1.6.

The final twist is 2 twist, in order to prevent the breakage of the sewing process.

This sewing thread has a good appearance and color fastness, similar to silk thread.

Elastic sewing thread: polyester filament current clothing popular stretch fabric, knitted garments, sportswear, fitness pants, female underwear, tights and development soon, but their sewing thread must have a matching the elastic elongation.

The elastic response string developed in China is more than 90%, and the elongation rate is 15% and more than 30% of the modified polyester filament stretch sewing thread, which can be used for the sewing of elastic materials.

Polyester staple fiber sewing thread: there are two kinds of polyester staple fiber sewing thread sold at present.

One is made of polyester filament cut and spun, one is made of polyester staple fiber spinning.

In terms of performance, the former is concerned with the general polyester staple line.

Because the polyester fiber has good abrasion resistance, high strength, low shrinkage, moisture resistance, corrosion resistance, resistance to decay, etc, so the polyester staple fiber sewing thread sewing industry is currently the main thread, and special functions, such as flame retardant and waterproof, etc.) with lines also often with polyester thread for processing.

As mentioned above, the gold and silver threads used to adorn the decoration are also made of polyester special processing.

Polyamide thread: nylon sewing thread has long silk thread, short fiber line and elastic deformation line.

Generally used for sewing chemical fiber, and clothing.

It is stronger, more elastic and lighter than polyester thread, but it has less wear and light resistance than polyester.

Nylon stretch sewing thread is made of polyamide 6 or polyamide 66 deformed elastic filament.

It is mainly used for sewing elastic knitted fabrics, bathing suits and underwear.

Polyamide transparent sewing thread can make the line trace not obvious because of the color of various fabrics that can be blocked by the line, which can help solve the difficulty of sewing wiring and simplify the operation.

Our country has developed polyamide monofilament transparent sewing thread.

The specification and technical conditions of its transparent sewing thread.
