Spun Twisted Yarn

Spun Twisted Yarn, commonly referred to as Polyester Spun Yarn or simply “Spun Yarn” in Chinese, is a high-performance textile material engineered from staple polyester fibers. The yarn is produced through a spinning process that aligns short polyester fibers, which are then twisted together to form a continuous, durable strand. This twisting process significantly enhances the yarn’s strength, cohesion, and dimensional stability, making it far more resilient than single-ply alternatives. Available in common linear densities such as 16s, 21s, and 32s, this yarn offers excellent versatility across various industrial and consumer textile applications.

Product production process

The primary advantage of Spun Twisted Polyester Yarn lies in its exceptional durability, low moisture absorption, and resistance to stretching, shrinking, and abrasion. These properties make it an ideal choice for sewing threads, especially in heavy-duty stitching where consistent tension and breakage resistance are critical. In the apparel industry, it is widely used for manufacturing workwear, uniforms, denim, and sportswear due to its ability to withstand repeated washing and mechanical stress without losing shape or color.

Beyond clothing, this yarn plays a vital role in home textiles. It is commonly woven into bed linens, curtains, upholstery fabrics, and decorative cushions, offering a smooth texture combined with long-lasting performance. Its resistance to mildew and chemicals also makes it suitable for industrial applications such as filter fabrics, conveyor belts, ropes, and webbings.

In the knitting sector, Spun Twisted Yarn is favored for producing gloves, socks, and knitted outerwear where elasticity and stitch definition are required. Additionally, it serves as a core component in composite yarns, often blended with cotton or viscose to improve fabric hand feel while maintaining structural integrity. Whether used in weaving, knitting, or sewing, this yarn delivers reliable performance across diverse end-uses, from fashion garments to technical textiles.
