Key Features

- Stable Elasticity with Good Recovery
The spandex core ensures reliable stretch and rebound performance, allowing fabrics to maintain flexibility and shape stability during use.
- Cost-Effective Production Solution
Compared to machine covered yarn, air covered yarn offers a more efficient production process, helping reduce manufacturing costs while maintaining stable performance.
- Lightweight and Breathable Structure
Air interlacing forms a less compact yarn structure, improving breathability and making the yarn suitable for lightweight and comfortable textile products.
- Smooth Processing Performance
With uniform yarn formation and stable tension, the yarn runs smoothly on knitting machines, supporting high-efficiency textile production.

Customization Service
Elasticity & Denier Adjustment
Spandex core and outer filament specifications can be customized to achieve different stretch levels and fabric performance.
Color Customization
A wide range of color options is available, including custom dyeing to match specific fabric designs and bulk production consistency.
Yarn Structure Optimization
Air pressure and interlacing parameters can be adjusted to control yarn cohesion, bulkiness, and surface characteristics.
FAQ
What is the main difference between air covered yarn and single covered yarn (SCY)?
Air covered yarn is produced by air interlacing, resulting in a softer and more bulky structure, while SCY is mechanically wrapped, offering a tighter and more compact yarn structure.
Does air covered spandex yarn have stable elasticity?
Yes. The spandex core provides consistent stretch and recovery, ensuring reliable elastic performance in textile applications.
What types of outer yarns can be used in ACY?
Common options include nylon and polyester filaments, which can be selected based on fabric requirements such as durability, softness, or cost.
