| Abstract | Treatment of cotton fabric with etherified methylolated melamine (MM) alone or in admixture with dimethylodihydroxy ethylene urea (DMDHEU) along with Pyrovatex Cp was investigated to render the cotton fabric crease resistant and flame retardant. The treatment was carried out under different conditions including nature of catalyst, ratios of EMM and DMDHEU in their binary mixture and incorporation of silicon-elastomers, other polymeric products, as well as pre-polymerized EMM in the treating solution. Of all several catalysts examined, ammonium sulphate proved to be the best one for combined easy-care and flame retardancy finishing using EMM/Pyrovatex Cp mixture. The use of EMM/DMDHEU at different ratios, along with Pyrovatex Cp, did not perturb the individual contribution of EMM and DMDHEU in nitrogen content, crease recovery and strength losses of the fabric. Flame retardancy was greater at higher ratios of EMM in the EMM/DMDHEU mixture. Incorporation of certain silicon elastomers in the EMM/Pyrovatex Cp treating solution enhanced the easy-care and flame retardancy properties of the finished fabric without adversely affecting strength properties. On the other hand, incorporation of pre-polymerized EMM in a treating solution containing EMM and Pyrovatex Cp caused substantial changes in easy-care and flame retarding properties of the finished fabric, depending upon the pH of both pre-polymerization and treating solution. The use of EMM pre-polymerization at pH 6 brought about a finished fabric with significant flame retardancy beside a crease recovery of 250-degrees and retained strength of ca. 77 %. |
