Alkali-soluble Polyester Chips for Sea-island Cotton Fiber
Alkaline Easy Soluble Saturated Polymer for Island-in-a-sea Cotton
Description: Alkali Soluble Polyester Chip is mainly used as the sea component of sea-island yarn. The alkali reduction processing dissolves the sea part and leaves only the island part. The separation of sea-island components is based on the different degrees of polymer dissolution in alkali solution. The conjugation with high contraction yarns generates excellent suede effects and resulting nanofibers have a large surface area, high absorption, and good distribution and filtration effects.
Alkali soluble polyester chip is mainly used for the production of microfiber sea-island POY and FDY, sea-island staple fiber. And the application of sea-island fiber is fashion fabric, artificial leather, high-performance wipes.
