Air-Textured Yarn (ATY) is a type of yarn made from continuous filament synthetic fibers through high-speed airflow processing. It utilizes airflow to cause bending, winding, and looping deformations in the individual filaments, endowing the yarn with fluffiness, elasticity, and a distinctive appearance. Air-textured yarn is widely used in various fields of textiles. 

The production process of air-textured yarn mainly includes the following steps: 

1. Raw fiber preparation: Select suitable continuous filament synthetic fibers as raw materials, such as polyester, nylon, and polypropylene. 

2. Feeding into the deformation nozzle: The continuous filament synthetic fibers are fed into the deformation nozzle, which has high-temperature and high-pressure air flowing inside. 

3. Airflow deformation: Under the action of high-speed airflow, the individual filaments of the continuous filament synthetic fibers undergo bending, winding, and looping deformations, forming a fluffy yarn structure.

4. Cooling setting: The deformed yarn is cooled by a cooling device to set its structure and maintain stability. 

5. Winding formation: The cooled and set air-textured yarn is wound into rolls for subsequent processing and use.
