We offer consistent quality and 24-hour response. Shipments go to Germany, Italy, Bangladesh, Pakistan, India, Sri Lanka, Turkey, Myanmar, Australia, Brazil, Chile, Argentina, and parts of Africa.
Yarn Range
- 100% spun polyester: Designed for strength, evenness, and abrasion resistance. Suitable for everyday socks, sport socks, and knit accessories. Typical counts cover 20s–60s. Single and multi‑ply options include 30s/1 and 40s/2 to match fabric hand‑feel, stitch density, and machine gauges.
- Polyester rubber covered yarn: Covered elastic yarn for stretch, recovery, and dimensional stability. It improves cuffs, ribs, arch support areas, and compression panels with uniform tension and consistent coverage.
- RCY 100#7575: This elastic option offers controlled elasticity, smooth coverage, and balanced tension for fewer breaks and stable high‑speed knitting. Available in raw white, black, and yellow with optional custom colors and spool specifications.
Colors, Finishes, and Packaging
We supply raw white for dyeing and dope‑dyed black and yellow for streamlined production. Custom color matching supports brand palettes with colorfastness designed for repeated washing and wear. Paper, plastic, and dye cones are available with adjustable weights to fit winding systems and dyeing processes. Export packaging protects yarn integrity during global transit and supports fast line changeovers.
Applications
- Socks: For casual and sport styles, this yarn maintains structure and helps reduce pilling. It supports clean loop formation at speed. It also pairs well with elastic zones to improve fit and abrasion resistance.
- Compression and support: Combine the core polyester yarn with the covered elastic to add targeted compression in cuffs and arches. This improves retention and shape after washing.
- Scarves and accessories: Select counts for the desired drape and hand‑feel. The material offers shape retention and stable color for a lasting appearance.
Custom OEM/ODM Solutions
We tailor counts, twist levels, and ply combinations to your machinery, gauge, and fabric targets. From sampling to bulk, our team aligns parameters for uniform loops, fewer end breaks, and consistent appearance. We match brand colors with shade‑lot control and offer finishes that improve knitting flow, reduce friction, and support colorfastness to washing and perspiration. Choose cone types and weights that fit dyeing or direct knitting. Flexible delivery schedules and protective packing support downstream efficiency. Request a quote to plan production.
Technical Specifications
Our spun polyester yarn is engineered for evenness and tensile performance. Controlled staple length balances strength, softness, and dye uptake. Counts range from fine to medium (20s–60s) with common 1–3 ply structures. High tensile performance with controlled CV and a uniform profile supports stable stitch formation and fewer end breaks. Dye uptake is reproducible, and colorfastness to washing and perspiration suits everyday socks and accessories. Paper or plastic cones are available in standard or custom weights.
