Investigation of the flammability properties of a cotton and elastane blend denim fabric in the presence of boric acid, borax, and nano-SiO2

Abstract This study contributes to the field of flammable resistant textiles. Boric acid, borax, and nano SiO2 were added to a commercial finishing solution, separate solutions were prepared for each. The difference in this study is to improve the functional finishing processes of denim fabrics consisting of 99% cotton and 1% elastane. The aim is to draw attention to the flame-retardant performance improvements that can be created by a synergistic mechanism for textiles. Using TGA, LOI and vertical combustion tests for determining flame retardant effect were sufficient to achieve meaningful and precise results. Each chemical added to increase the flammability performance effect of the commercial finish solution entered the fabric surface structure, and the flammability performance of the commercial finish solution was improved by a simple and feasible method. Denim fabric can be made suitable for industrial textiles by flame retardant finishing process.
