Abstract
The flame resistant finishing of silk fabric is still a challenge because most of the available treatment methods usually result in insufficient laundering durability In this paper a vinyl phosphorusbased monomer diethyl2methacryloyloxyethyl phosphate DEMEP was applied onto silk fabrics by graft copolymerization technique using potassium persulfate as an initiator FTIR spectra and amino analysis showed the evidence of the reaction between DEMEP and silk The silk fabrics treated with DEMEP have excellent selfextinguishing property when the DEMEP addon is over 50 wt of silk fabrics The LOI of treated samples is at least 28 when the weight gain is 10 After being subjected to 30 hand wash cycles DEMEP treated silk fabric can still pass the vertical flammability test Thermal gravimetric TGA and differential thermal analysis DTA were applied to explore the thermal decomposition of silk fabrics treated with DEMEP The initial decomposition temperature of silk fabric treated with DEMEP was shifted to a lower temperature And at the end of decomposition at 700 °C the char residue of silk fabric treated with DEMEP was higher than that of the control sample
