Abstract:
... Polyester fabric (PET fabric) has aroused widespread attention from people thanks to the advantages of smooth feel, easy washing, quick-drying, high strength, and chemical resistance. However, PET fabric's wide application has been limited by its hydrophobicity, poor resistance to bacterial contamination, and static accumulation. Herein, a super-hydrophilic PET fabric was achieved via a spray-dryi ...
