Import Air Covered Spandex Yarn — Buy in Bulk from Supplier in China

Air covered spandex yarn from Zhuji Jinzong Knitting Co., Ltd. is a composite yarn combining polyester or nylon filament (DTY/FDY) with spandex core, produced in a range of deniers and spandex ratios for stretch fabrics. The supplier’s standard offerings include 75 DTY paired with 15, 20, or 40 denier spandex, up to 600 DTY with 40 or 70 denier spandex, available in raw white (rw) and black. These configurations target circular knitting machines, both large and small, for applications like socks, sweaters, jeans, woven cloth, and seamless underwear.

The yarn’s construction uses air-jet covering to encase the spandex core, providing elasticity while the outer DTY or FDY delivers durability and colour consistency. Typical industry specifications for such yarns include elongation at break of 100-200% (standard for spandex-based composites), tenacity of 3-5 cN/dtex (standard for DTY/FDY), and a moisture regain of 0.4-0.8% (standard for synthetic fibres). The supplier’s range also includes FDY-based variants from 100 to 250 denier with 40 denier spandex, suitable for finer, smoother fabrics.

Buyers use this yarn for stretch garments where recovery and shape retention are critical, such as sportswear, hosiery, and form-fitting apparel. The product is packed on paper cones, polybagged, and shipped in export cartons. For bulk orders, confirm compatibility with your knitting machines, as the yarn’s denier and spandex ratio directly affect stitch definition and fabric stretch. Origin is Zhejiang, China, with logistics typically arranged via Shaoxing’s industrial hubs.
