Overview
Polyester knitted fabric is a synthetic textile made from polyethylene terephthalate (PET) fibers, knitted into a flexible, stretchable structure. It has become one of the most widely used fabrics in the textile industry due to its combination of performance characteristics and cost-effectiveness. The knitting process creates loops of yarn that interlock, giving the fabric inherent elasticity. This distinguishes it from woven polyester fabrics, which tend to be more rigid. Polyester knitted fabrics are available in various weights, from lightweight jersey to heavier interlock constructions.
Product Features
The key attributes of polyester knitted fabric include excellent durability and resistance to abrasion, making it long-lasting even with frequent use and washing. Its synthetic nature provides inherent wrinkle resistance and dimensional stability, maintaining its shape well over time. Polyester's hydrophobic properties make it quick-drying and moisture-wicking, ideal for activewear. Modern treatments can enhance these properties or add functionalities like UV protection, antimicrobial properties, or improved breathability. The fabric accepts dyes well, offering vibrant color options with good colorfastness.
Main Uses
In apparel, polyester knitted fabrics are extensively used for T-shirts, leggings, sportswear, underwear, and casual wear due to their comfort and ease of movement. The sportswear industry particularly values these fabrics for performance clothing that requires moisture management and stretch. Beyond clothing, polyester knits are used in home textiles like upholstery, bedding, and curtains. Industrial applications include automotive interiors, medical textiles, and technical fabrics where specific performance characteristics are required.
Culture and Development
Polyester fibers were first developed in the 1940s, with knitted versions gaining popularity in the 1960s as synthetic fabrics became more accepted. The oil crises of the 1970s boosted polyester's popularity as a cost-effective alternative to natural fibers. Today, sustainability concerns have led to developments in recycled polyester (rPET) knitted fabrics, made from post-consumer plastic bottles. This eco-friendly version maintains the same performance characteristics while addressing environmental concerns about synthetic textiles.
B2B Procurement Guide
When sourcing polyester knitted fabrics commercially, consider the fabric weight (measured in GSM), which affects durability and drape. Heavier weights (180-300 GSM) are better for structured garments, while lighter weights (120-180 GSM) suit flowing designs. Verify the fabric's stretch and recovery properties based on your product requirements. Request samples to test shrinkage, colorfastness, and pilling resistance. For large orders, negotiate pricing based on volume and consider minimum order quantities. Reliable suppliers should provide technical specifications and compliance certificates for specific applications.
