Small holes in high-quality acetate yarn make it a light material like a bird feather, but in everyday life the strength as a fabric decreases and its value as a product disappears. However, when combined with polyester hollow fiber and air processing, the quality is complemented and turns into a quality material as a fiber.

​

In addition, when it is combined through inter mingling of Cation Acetate 120 Denier and Polyester 75 Denier anti-electrostatic hollow fiber to use as fabric material for sweaters, or when it is developed as inner wear by forming and weaving at high gauge, a high added-value product is predicted to be completed.

The reason why cation acetate is used here is because it is to supplement the low dyeing solidity of acetate, and polyester is used to prevent unpleasant feelings due to electrostatic.
