The 907575 Fine Durable Double Covered Yarn represents a high-performance solution for premium sock manufacturing, designed to deliver exceptional comfort and longevity. Its unique double-layer construction features a high-quality spandex core (20% by weight) wrapped in two layers of premium polyester—an inner binder wrap and an outer cover wrap—creating a yarn with unmatched elasticity (8–10% stretch range) and superior durability. This design ensures socks hug the foot snugly without sagging or bunching, making it ideal for both athletic and everyday wear where fit and performance are paramount.

Our 907575 polyester spandex double covered yarn is a specialized, high-durability textile solution purpose-built for sock and hosiery production enterprises. Manufactured by Longtai in Zhejiang, China, this premium 90# 907575 model features a unique double-layer construction: a 20% high-performance spandex core wrapped in two reverse-spiral layers of 80% high-tenacity polyester filament (inner binder wrap and outer protective cover). With 8–10% uniform stretch and 98% elastic recovery after 1,000+ stretch cycles, this industrial hosiery yarn delivers a snug, non-slip fit, exceptional abrasion resistance, and long-lasting shape retention for all types of sock manufacturing.
Our bulk double covered yarn for socks delivers a Martindale abrasion resistance rating of 50,000+ cycles, with dual polyester layers that reinforce high-friction areas like toes and heels. It extends finished sock lifespan by 30% compared to single-covered yarn alternatives, reducing return rates and enhancing brand reputation for bulk buyers.
Every batch of this industrial sock knitting yarn is engineered for consistent tension and zero core exposure, ensuring smooth, uninterrupted operation on high-speed automatic sock knitting machines. This minimizes yarn breakage, downtime, and defect rates, maximizing production efficiency for large-run hosiery manufacturing.
Our OEKO-TEX certified hosiery yarn holds OEKO-TEX® Standard 100 (Class II) and Bluesign® certifications, meeting strict international safety and environmental standards for skin-contact products, with full compliance for EU, North American, and global market distribution.

Our double covered yarn manufacturing process uses precision mechanical wrapping systems to apply two reverse-spiral polyester layers around the spandex core, ensuring full coverage, zero core exposure, and uniform elasticity across every roll. We enforce a strict 6-step quality control protocol: raw material polymer and spandex incoming testing, in-line wrapping uniformity monitoring, real-time tension calibration, post-production elasticity and abrasion testing, batch consistency verification, and pre-shipment compliance and safety checks. This guarantees reliable performance for every production run.
Athletic & Performance Socks: Running, basketball, and soccer socks requiring dynamic support, moisture wicking, and blister prevention
Medical Compression Hosiery: 15–20 mmHg graduated compression stockings with consistent, controlled pressure distribution for circulatory support
Premium Fashion & Dress Socks: Luxury dress socks, sheer tights, and patterned hosiery with a smooth finish, minimal bulk, and excellent pattern retention
Everyday Casual & Children’s Socks: Soft, hypoallergenic daily wear socks and pediatric hosiery, with non-irritating materials suitable for sensitive skin
For optimal sock knitting results, use 28–32 gauge needles with standard sock knitting machines, with adjusted tension settings to accommodate the yarn’s elasticity and prevent stitching distortion. Store this high-durability hosiery knitting yarn in a dry, well-ventilated warehouse at 10–30°C, with relative humidity of 35–65%. Avoid direct sunlight, extreme temperature fluctuations, high humidity, and contact with corrosive chemicals to preserve elastic performance and structural integrity.
We offer flexible MOQ options to fit both small-batch custom hosiery production and large-scale mass manufacturing, with exclusive tiered pricing for bulk orders.
