Alkali-soluble Polyester Chips for sea-island yarn spinning

Alkaline Soluble Polyester Chips are a type of modified polyester, produced by incorporating hydrophilic groups into conventional polyesters. These products can hydrolyze in heated alkaline (or water) solutions. They primarily serve as the marine component in the production of sea-island yarns, where the sea portion is dissolved through alkali reduction, leaving behind the island structure. The segregation of sea-island components relies on the degree of polymer dissolution in alkaline solutions. When conjugated with high-shrinkage yarns, a superior suede effect is achieved, producing nanofibers with extensive surface area, high absorption, and efficient distribution and filtration capabilities.

 

Features:

1. Excellent spinnability for smooth and efficient processing.
2. High thermal stability, ensuring reliable performance under heat.
3. Extended lifespan of spinning components, reducing maintenance frequency.
4. Clear sea-island component interfaces, enabling precise structural definition.
5. Low-ratio, high-efficiency compounding (15 sea:85 island) for superior output.
6. Easily dissolvable sea components, simplifying post-processing.
7. Deep dyeability of island components, enhancing coloration quality.

 

Applications:

1. Solo Spinning for Fiber: Primarily aimed at developing specialty textiles.
2. Compound Spinning: Focused on producing ultra-fine sea-island POY and FDY, along with sea-island staple fibers. Applications of sea-island fibers mainly include fashion fabrics, and synthetic leather.
