What are the applications of high-strength, low-shrinkage, flame-retardant polyester filament yarn (including colored ones)
2026-01-05
high-strength, low-shrinkage, flame-retardant polyester filament yarn (including colored ones) is a functional polyester fiber made through raw material modification, process optimization, and dope coloring. It combines four major advantages: stable mechanical properties, resistance to dimensional deformation, flame retardant safety, and long-lasting color. It is widely used in industrial and civilian fields where safety, durability, and color consistency are strictly required. Specific applications are as follows:
1.Industrial protective and safety equipment
It is the core raw material for making flame-retardant protective clothing, firefighter uniforms, and electric welder suits. Its high-strength characteristics ensure that the clothing is resistant to wear and tear, making it suitable for high-intensity work scenarios such as rescue operations and welding. The low shrinkage property ensures that the clothing will not deform due to shrinkage in high-temperature environments, thus affecting movement. The flame-retardant property effectively blocks the spread of flames, reducing the risk of burns. The original liquid coloring process makes the fabric color fast, ensuring no fading even after long-term washing and exposure to sunlight. At the same time, it avoids environmental pollution caused by the dyeing process, meeting the safety and compliance standards for industrial protective clothing.
2.Transportation interior and components
Used for interior fabrics, seat fabrics, seat belts, and ceiling cloths in vehicles such as automobiles, high-speed trains, and airplanes. The transportation industry has extremely high requirements for flame retardancy of materials (for example, automotive interiors must meet the FMVSS 302 flame retardancy standard). This fiber can effectively delay the spread of fire; its low shrinkage property ensures dimensional stability of interior parts when exposed to sunlight and temperature changes over a long period, preventing wrinkling and deformation; its high strength enhances the durability of seat belts and seat fabrics, extending their service life; its color-containing property meets the diverse color requirements of vehicle interiors, eliminating the need for post-production dyeing and reducing the risk of color variation in production processes.
3.Building and decorative materials
Suitable for flame-retardant curtains, fireproof carpets, decorative wall coverings, and geogrid in the construction field. In densely populated places such as high-rise buildings, shopping malls, and hotels, flame-retardant fibers can reduce fire hazards; low shrinkage performance allows curtains and wall coverings to hang without shrinking or deforming for a long time, maintaining their appearance; high strength characteristics enhance the tensile strength of geogrid, which is used in engineering scenarios such as subgrade reinforcement and slope protection; the color stability of the original liquid coloring can meet the requirements of architectural decoration for color durability, avoiding fading due to sun exposure and rain.
4.Home textiles and public area supplies
Used for home textile products in public settings such as hotel bedding, hospital curtains, and school dormitory fabrics. The flame retardant properties meet fire safety regulations for public places, while the low shrinkage property ensures that the bedding and curtains maintain their size after multiple washes. The high strength characteristic enhances durability and reduces the frequency of replacement. The color retention property ensures uniform color and minimal fading of the product, while also reducing the discharge of dyeing wastewater, aligning with the green and environmentally friendly industry trend.
5.Industrial textiles
Produce flame-retardant tarpaulins, tent fabrics, cable covering materials, and filtration materials. Tarpaulins and tents need to be exposed outdoors for long periods, and their low shrinkage properties ensure dimensional stability under temperature fluctuations. Their high strength characteristics provide wind resistance and tear resistance, while their flame retardant properties enhance safety for outdoor use. Cable covering materials utilize their flame retardant and low shrinkage properties to prevent the spread of fire in case of cable short circuits and fires. Filtration materials can maintain structural stability in high-temperature, flammable environments (such as industrial exhaust gas filtration), combining flame retardant and filtration efficiency.
