1.mechanical property
High strength: It has a high breaking strength. Compared with ordinary polyester filament, high-strength and low shrinkage colored polyester filament can withstand greater tensile force and is not easy to break. This enables high-strength and low shrinkage colored polyester filament to ensure good durability and stability when used in the manufacture of various textiles or industrial products, such as in the production of ropes, seat belts, and other products, which can withstand significant weight and tension.
Low shrinkage: Under high temperature or other environmental conditions, the shrinkage rate of high-strength, low shrinkage colored polyester filament is relatively low. This characteristic makes fabrics or products made from this filament have good dimensional stability, and are not easily deformed during processing and use. They can maintain their original shape and size, improve product quality and accuracy, and are suitable for fields that require high dimensional stability, such as aerospace and automotive interiors.
2.optical performance
Color characteristics: It has a rich and diverse range of colors, and the colors are bright and vibrant. These colored polyester filaments undergo special dyeing processes during the production process, resulting in high color fastness and resistance to fading. They can meet the color needs of different users and provide more color options for product design and manufacturing. They can be widely used in fields with high color requirements such as clothing and home textiles.
3.Thermal performance
Flame retardancy (flame retardant filament): It has good flame retardancy and can effectively prevent the spread of flames. When encountering a fire source, flame retardant filament will inhibit the combustion reaction and reduce the combustion rate through the chemical structure of high-strength and low shrinkage colored polyester filament and the added flame retardant substances. It can even quickly extinguish itself after the fire source is removed, greatly improving the safety during use. It can be used in places with high fire safety requirements, such as building interiors, transportation interiors, firefighting suits, etc.
Thermal stability: Both ordinary high-strength low shrinkage colored polyester filament and flame-retardant filament have good thermal stability. Within a certain high temperature range, its mechanical and physical properties will not undergo significant changes, and it can maintain good performance and withstand some processing techniques that require high temperature treatment, such as heat setting and hot pressing.
4.chemical performance
Chemical resistance: It has good resistance to many chemicals and is not easily corroded by chemicals such as acids, alkalis, and organic solvents. This enables high-strength and low shrinkage colored polyester filament to maintain stable performance in different chemical environments, making it suitable for use in situations where it may come into contact with chemicals, such as industrial filter materials, chemical protective clothing, etc.
Aging resistance: It has good aging resistance, and is not susceptible to aging degradation caused by light, oxygen, heat and other factors during long-term use and storage. Its molecular structure is relatively stable, which can maintain its original performance and extend the service life of the product.
5.Other performance
Good wear resistance: The surface is smooth, the friction coefficient is small, and it also has high strength, therefore it has good wear resistance. During use, it can resist various friction effects, is not prone to fuzzing or pilling, maintains the smoothness and integrity of the fabric surface, and improves the durability of the product. It is suitable for making items that are frequently subjected to friction, such as cuffs, collars, backpack straps, and other parts of clothing.
Moisture absorption and quick drying: The moisture absorption is low, but it has a certain core absorption effect, which can quickly transfer moisture from the inner layer to the outer layer of the fabric, achieving rapid drying. This feature makes clothing made from this filament more comfortable to wear, maintaining relative dryness even in humid environments and reducing discomfort caused by sweat or moisture accumulation.
