Flame Retardancy of Silk Fabrics by Graft Copolymerization with Phosphorus-based Monomer
A reactive vinyl phosphorus-based monomer dimethyl methacryloyloxyethyl phosphate (DMMEP) was applied onto silk fabrics by graft copolymerization technique initiated by potassium persulfate to give silk fabrics durable flame retardancy. AIR spectra and amino analysis showed the evidence of the reaction between DMMEP and silk fabrics. DMMEP treated silk fabrics have excellent flame retardancy with its LOI 30.3 % and char length 56 mm. And After 30 home laundry cycles, it still has good flame retardancy with LOI 29.5%. This treatment has very little effect on tensile strength and whiteness of silk fabrics. It only has slight decrease, which is totally negligible. Thermogravimetric analysis (TGA) shows that DMMEP treated silk fabrics decompose at lower temperature and can produce more char residue than control sample, which evidently shows that DMMEP works as a condensed-phase flame retardant.
