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. T

hey 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.
