Abstract: Abstract: The water-soluble polybutylene terephthalate (WSPBT) was prepared through adding other modified monomer when synthesizing the polybutylene terephthalate (PBT). This WSPBT can be crystallization easily and can dissolution in the boiling water. The existence of SIPE was proved by the FTIR analysis. The thermo-gravimetric analysis(TGA) shows that the WSPBT has good thermal stability. The island-in-sea fiber which composed with WSPBT and common PET was prepared through composite spinning. The island-in-sea fiber were set in boiling water about 45 minutes, then water-soluble property of WSPBT can be tested. The relationship of SIPE content in WSPBT and water-solubility property was discussed.
