Application
- Knitted Fabrics: Spandex jersey, rib knit, air-layer knit, terry cloth, etc., used for adding stretch to sportswear, casual wear, sweatshirts, and outerwear, giving the fabric both elasticity and crispness.
- Sports Apparel: Sports pants, sports vests, yoga pants, fitness wear, skiwear, etc., utilizing their high elasticity, abrasion resistance, and washability to accommodate significant stretching during exercise while maintaining a crisp shape.
- Webbing and Elastic Bands: Knitted elastic bands, binding tape, shoulder straps, waistbands, etc., used for elastic parts in clothing, bags, and home textiles, providing stable elasticity and resistance to breakage.
- Socks: Cuffs and bodies of mid-to-high-end sports and casual socks, providing comfortable elasticity, abrasion resistance, and resistance to pilling, extending the lifespan of the socks.
- Other Applications: Home textiles (elastic edges for sofa covers and curtains), work safety products (elastic gloves, elastic parts for protective clothing), toys (elastic fabrics), etc.
FAQ
1. What does "3075" specifically mean in SCY 3075? How does it differ from other specifications?
Core meaning: "30" represents the spandex core yarn specification of 30D (D stands for denier; the smaller the number, the finer the core yarn and the more delicate the elasticity); "75" represents the polyester covering yarn specification of 75D (the larger the number, the thicker the covering yarn, and the thicker and more durable the yarn overall).
Differences from other specifications: Compared to SCY 3050 (30D spandex + 50D polyester), SCY 3075 is thicker, more durable, and has better crispness; compared to SCY 4075 (40D spandex + 75D polyester), SCY 3075 has a more delicate elasticity and a softer hand feel, suitable for applications requiring moderate elasticity and sturdiness.
2. Is SCY 3075 single-covered or double-covered? Which knitting processes is it suitable for?
- SCY 3075 is a single-cover (SCY) yarn, where a single layer of polyester filament is spirally wrapped around a spandex core filament. It offers greater elasticity and lower cost, making it the most commonly used type of polyester-spandex covered yarn (polyester-spandex is mostly covered in a single-cover method).
- Compatible Processes: Primarily compatible with circular knitting machines, flat knitting machines, and ribbon weaving machines. It can be used for the production of knitted fabrics, webbing, and socks, especially suitable for high-speed knitting, ensuring smooth operation and reducing yarn breakage.
3: What is the difference between SCY 3075 spandex-polyester covered yarn and nylon-spandex covered yarn (such as SCY 3075 nylon-spandex)? How should you choose?
- SCY 3075 spandex-polyester: Abrasion-resistant, crisp, with high colorfastness, low cost, and moderate elasticity. Suitable for sportswear, outerwear, webbing, casual socks, and other applications requiring high crispness and abrasion resistance, while maintaining a moderate level of skin-friendliness.
- SCY 3075 Spandex: Softer to the touch, better skin-friendly, and with finer elasticity, but less durable and less crisp than polyester/spandex, and more expensive. Suitable for underwear, tights, and other applications where skin-friendliness is paramount.
- Selection Conclusion: For those seeking value for money and prioritizing durability and crispness, choose SCY 3075 spandex/polyester; for those prioritizing softness and a sufficient budget, choose nylon/spandex covered yarn.
