Cellulose-based PFC-free Functional Surface Finish

詳細技術說明: Traditionally, water-repellent surface finishes are achieved by using perfluorochemicals (PFCs), which are toxic chemicals hazardous to humans and the environment. This entry is a new water-repellent surface finish using natural and recycled materials obtained from textile waste, which is a safer alternative to PFCs on textiles. The project has developed a novel water-repellent surface finish that makes use of PFC-free recycled cellulose material through a two-step chemical process: firstly, a hydrophobic modification of the recycled cellulose powders to make them water repellent; secondly, adding functional additives to improve the washing durability properties of the fabric.
