Trying to choose between nylon SCY and polyester SCY? Here’s the no-fuss breakdown:

Nylon 4070 SCY

• Feels: Super soft, silky, with a subtle shine

• Perks: Stretches well, bounces back, gentle on skin

• Best for: Premium underwear, lingerie, soft activewear

• Tip: Avoid heat over 150°C

Polyester SCY

• Feels: Sturdier, slightly stiffer (no luxury touch)

• Perks: Durable, wrinkle/shrink-resistant, budget-friendly

• Best for: Socks, sportswear linings, everyday bulk clothes

• Tip: Handles high heat (up to 265°C)

1. Q: Can nylon 2070 SCY be used for machine washing?

A: Yes! It holds shape well after repeated machine washes, but we recommend using a gentle cycle and avoiding high-temperature drying to preserve its silky texture.

2. Q: Is polyester SCY suitable for outdoor apparel?

A: Absolutely. It has excellent UV stability and mildew resistance, making it a great choice for outdoor sportswear linings and durable activewear that’s exposed to the elements.

3. Q: Why choose nylon 4070 SCY over polyester SCY for lingerie?

A: Nylon 4070 SCY has a luxuriously soft, skin-friendly handfeel and subtle sheen that elevates lingerie quality, while polyester SCY is stiffer and lacks that premium tactile finish needed for delicate intimate wear.

Characteristics of SCY Yarn (Mechanical Covered Yarn / Spandex Covered Yarn)

SCY (Mechanical Covered Yarn) is an elastic yarn formed by mechanically wrapping and twisting outer filaments around a stretched spandex core. Its key characteristics are as follows:

1.Crisp and Smooth Fabric Style

Due to the mechanical twisting process, SCY has stable twist, giving fabrics a crisp, smooth, and structured feel. It is suitable for garments requiring good shape retention.

2.No Core Exposure & Good Quality Stability

The outer fibers are tightly wrapped around the core, preventing exposure. Apart from potential twist unevenness, it has fewer quality issues during spinning and weaving, resulting in better finished product appearance.

3.Elasticity & Strength

Inherits the high elasticity of the spandex core, with elongation primarily determined by spandex performance. Yarn strength depends on the outer fiber, offering excellent tensile recovery.

Twist level directly affects performance: appropriate twist increases cohesion, improves strength, and enhances evenness.
