Journal Textile Coloration and Finishing Year / Vol., Issue, Month 2022 / V.34,no.4,Dec Title Dual-curable Flame-Retardant Finish of Silk Fabrics Using a Water-soluble Cyclophosphazene Derivative Authors Jeong-Hwan Kim, Ji-Yun Baek, and Jinho Jang Institution/Affiliations Kumoh National Institute of Technology Pages/Total page pp.217 ~ 223 / 7 Language Korean Abstract Flame-retardant finished silk fabrics could release carcinogenic formaldehyde resulting from the conventional finishing agents. New water-soluble cyclophosphazene derivative can be used as a formaldehyde-free flame retardant for the silk protein. Dichloro tetrakis{N-[3-dimethylamino)propyl]methacrylamido}cyclophosphazene(DCTDCP) can be cured by heat or UV irradiation as a durable flame retardant for the silk fabrics. Treatment conditions were optimized including curing temperature and time, finishing formulations, and UV energy. At the 30% DCTDCP application, peak HRR and THR decreased by 42.6% and 49.6% respectively compared to the pristine silk fabrics. Also char residue increased up to 48% from 11% indicating solid-phase retarding mechanism. The flame-retardant silk fabrics showed a LOI of 31.1 and the washed sample maintained a LOI of 26.8 even after ten laundering cycles.
