907575 Fine Durable Double Covered Yarn for Socks

Product Overview

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.

Product Specifications

Product Features

Superior Fit: The double-covered structure provides 360° uniform stretch, adapting to varying foot shapes (narrow, wide, or standard) while maintaining consistent compression and support.

Longevity: Reinforced by dual polyester layers, the yarn resists wear in high-friction areas (toes, heels) and extends product lifespan by 30% compared to single-covered alternatives.

Moisture Wicking: The outer polyester layers feature a hydrophilic finish that draws sweat away from the skin, while the inner layer accelerates evaporation, keeping feet dry and comfortable.

Temperature Regulation: Engineered with a breathable core that adapts to ambient temperatures, keeping feet cool in summer (via moisture wicking) and warm in winter (via thermal retention).

Applications

Athletic Footwear: The top choice for running socks, basketball socks, and soccer socks, where dynamic support, fit, and moisture management enhance performance and reduce blisters.

Medical Compression: Used in graduated compression stockings (15–20 mmHg) for improving blood circulation, with controlled stretch that ensures consistent pressure distribution.

Fashion Hosiery: Ideal for sheer tights, premium dress socks, and luxury legwear due to its smooth finish, minimal bulk, and ability to hold intricate patterns.

FAQ

Q: Is this yarn suitable for children’s socks, and does it irritate sensitive skin?

A: Yes. Its soft, smooth texture and hypoallergenic materials make it suitable for pediatric use, with no reported skin irritation in clinical tests.

Q: What is the recommended needle size for knitting, and does it require special machine settings?

A: We recommend 28–32 gauge needles for optimal results. It works with standard sock knitting machines, though adjusting tension settings to account for elasticity is advised.

Q: How does the double covering protect the spandex core from degradation?

The dual polyester layers shield the spandex from UV radiation, chlorine, and friction—common causes of spandex breakdown—extending its functional life by up to 50% compared to exposed spandex cores.
