Journal Textile Coloration and Finishing Year / Vol., Issue, Month 2022 / V.34,no.1,Mar Title Formaldehyde-Free Durable Flame-Retardant Finish of Cotton Fabrics Using Vinyl Bisphosphonic Acid and Acrylamide Authors Mi-Ji Jang and Jinho Jang Institution/Affiliations Kumoh National Institute of Technology Pages/Total page pp.1 ~ 9 / 9 Language Korean Abstract The durable FR treatments such Pyrovatex and Proban have been used for cotton fibers, while the finishes involve toxic ammonia or formaldehyde release during finishing process or finished products. In this study, ecofriendly flame-retardant treatment of cotton fabrics was carried out using UV-curable formulations of Vinyl bisphosphonic acid (VBPA), Acrylaminide and Triacryloylhexahydro-1,3,5-triazine, as a monomer, a comonomer and a cross-linking agent respectively, which can introduce a cross-linked copolymer networks. With an optimal finish formulation, the flame retardancy of LOI 29.8 was maintained even after 10 laundering cycles. In TGA analysis, the DTGA peak decreased from 389℃ to 252℃ and the amount of char yield increased from 6.1% to 46.1% compared to the untreated cotton. In addition, MCC analysis showed that Peak HR and THR decreased by 59.4% and 69.2% respectively, compared to the untreated cotton. The pyrolysis and combustion behaviors of the FR-treated cotton implied a condensed-phase flame-retarding mechanism.
