Sewing thread is the thread required for knitted clothing products. Sewing thread can be divided into three categories according to raw materials: natural fiber, synthetic fiber sewing thread and mixed sewing thread. Sewing thread is mostly made of pure polyester fiber.
What is polyester sewing thread
Polyester is a polymer that is spun into fibers. It mostly refers to fibers produced with ethylene phthalate as raw material. Polyester fiber is a high-quality synthetic fiber. The sewing thread made from it has high strength, good wear resistance, good color fastness, good light resistance, and is not easy to fade.
Polyester sewing thread is also called high-strength sewing thread. It refers to sewing thread produced with polyester as raw material. The polyester sewing thread is strong and does not reduce strength when wet. It has a small shrinkage rate. After proper shaping, it shrinks less than 1%, so the sewn stitches can remain flat and beautiful. The sewing thread and the fabric can maintain consistent expansion and contraction without shrinkage.
Polyester sewing thread is a sewing thread made of polyester fiber, which is usually used for sewing knitted clothing products. Polyester sewing thread has the characteristics of wear resistance, low shrinkage, and good chemical stability. It has replaced cotton sewing thread in many occasions and is widely used in the sewing of cotton fabrics, chemical fibers and blended fabrics.
Characteristics of polyester sewing thread
- Strength and wear resistance: Polyester sewing thread has high strength and good wear resistance, making it very durable and not easy to break or break. This is mainly due to the characteristics of polyester fiber.
- Heat resistance: Polyester fiber has good heat resistance and can maintain stability in high temperature environments. It is not easy to deform or melt. Therefore, polyester sewing thread is suitable for clothing and fabrics that require high-temperature ironing or high-temperature treatment.
- Light resistance: Polyester fiber has good light resistance and is not easy to fade or turn yellow. This means that products made with polyester sewing thread can maintain bright colors for a long time in the sun.
- Shrinkage: Polyester fiber has a small shrinkage rate, and shrinks less than 1% after proper shaping, which means that the sewn stitches can always remain flat and beautiful without shrinkage.
- Chemical stability: Polyester sewing thread is chemically stable, which means it is not easily affected by chemicals and can maintain good performance.
- Color and color fastness: Polyester sewing thread has a full range of colors, good color fastness, and is not easy to fade or change color.
Conclusion
Polyester sewing thread has good color fastness and elongation, high toughness, low shrinkage, uniform twisting, no knots, corrosion resistance, mildew resistance, wear resistance, high and low temperature resistance, and is suitable for high-speed sewing.
Polyester sewing thread has many types such as filament, staple fiber and polyester low-elastic silk thread, and is widely used in clothing products, leather products, military products and other fields due to its high strength, good wear resistance, no knots, light resistance and other good performance characteristics.
