- Abstract:
- ... Polyethylene terephthalate (PET) has been widely used as a basic material in fabrics for a wide range of applications owing to its excellent physicochemical and mechanical properties such as excellent mechanical strength, easy treatment, quick drying and dimensional stability. However, conventional PET-based fabrics always suffer from several issues mainly related to bad surface wettability and po ...
