What is the main function of High strength and low shrinkage colored polyester filament
2026-01-22
High strength and low shrinkage colored polyester filament is a functional polyester filament made through processes such as raw material modification, stretching and shaping, and original liquid coloring. It combines the three core advantages of "excellent mechanical properties, strong dimensional stability, and long-lasting color" and is widely used in industrial weaving, home textile clothing, outdoor products, and other fields. Its specific functions are as follows:
1、 Industrial field: strengthening of load-bearing structures and durability protection
This is its core application direction, relying on the characteristics of high strength and low shrinkage to adapt to the needs of industrial scenarios:
Reinforced composite material skeleton
As the core weaving material for geogrids, conveyor belts, tarpaulins, and ropes, high strength characteristics can enhance the tensile strength, tear resistance, and wear resistance of products; Low shrinkage rate (dry heat shrinkage rate ≤ 3%) ensures the dimensional stability of the product under high temperature and high load conditions (such as outdoor geotechnical engineering, mining transportation), without shrinkage deformation, and avoiding structural failure.
Industrial fabric functional adaptation
Used for producing waterproof canvas, fireproof curtains, building film materials, etc., with low shrinkage to ensure that the fabric is not easily wrinkled or deformed in cold and hot cycles; The coloring process of colored original solution ensures uniform color and strong weather resistance of the product, which can be used for outdoor identification industrial products (such as warning tarpaulins and safety fences), with both protective and visual recognition functions.
Automotive textile component substrate
Used for automotive interior fabrics, seat belts, tire curtain fabrics, etc., it has high strength to meet the load-bearing and wear-resistant requirements of components, low shrinkage to avoid fabric shrinkage and loosening after high temperature exposure, and colored filament can reduce the later dyeing process and lower environmental costs.
2、 Home textile and apparel industry: improving product quality and appearance
Balancing the shaping and aesthetics of home textile products
Used for curtains, sandpaper, bedding fabrics, etc., the low shrinkage rate ensures that the fabric is not easily shrunk or deformed after multiple washes and high-temperature ironing, maintaining a flat pattern; The colored filament colored with original solution has high color saturation and good color fastness (sun and friction resistance color fastness ≥ 4 levels), is not easy to fade, and does not require subsequent printing and dyeing, making it more environmentally friendly.
Functional upgrade of clothing fabrics
Used for outdoor clothing, sportswear, workwear fabrics, etc., the high-strength characteristics enhance the fabric's resistance to stretching and wear, extending the service life of the clothing; Low shrinkage ensures that clothing does not deform after wearing and washing; Colored long filaments can be directly woven to produce rich colors, eliminating the dyeing process, improving production efficiency, and avoiding pollution from printing and dyeing wastewater.
3、 Outdoor products field: combination of weather resistance and practicality
Used for outdoor products such as tents, hiking ropes, backpack fabrics, sunshade nets, etc., with high strength to meet the load-bearing and wind resistance needs in complex outdoor environments; Low shrinkage makes it dimensionally stable in high temperature exposure, low temperature rain and snow weather, and less prone to aging and deformation; The weather resistance of colored filament ensures that the product remains brightly colored even after long-term outdoor use, combining practicality and aesthetics.
4、 Technological and environmental advantages: cost reduction, efficiency improvement, and green production
Simplify the production process
Colored filaments colored with original liquid do not require subsequent dyeing and printing processes. After weaving, they can be directly made into finished products, shortening the production cycle and reducing the dyeing and processing costs and equipment investment of enterprises.
Green environmental characteristics
Reduce water consumption, energy consumption, and wastewater discharge during the printing and dyeing process, in line with environmental policy requirements, especially suitable for foreign trade export orders with strict environmental standards.
