It was achieved by chemical cross-linking reaction of partially-depolymerized PET and natural fiber hydroxyl group. Natural fiber fabric was modified by pad- mangle-dry-cure line at collaborating textile-finishing company by using a water mixture of wet-milled partially-depolymerized PET dispersion and a cross-linking agent. After sublimation printing, we made preproduction scarves. 䠉 35 䠉
