Effect of Gray Fabric Properties on Flame Resistance of Knitted Fabric

Abstract

In this study, knitted fabrics that have been used extensively in recent years are chosen to investigate the effects of their properties on flame resistance. Physical parameters (fiber type and composition, yarn count, yarn twist coefficient, fabric design, weight per unit area, air permeability, fabric thickness, cover factor, loop density) that affect fabric flammability are defined and an experimental study is designed. The burning behavior of the all fabrics is evaluated using the BS 5438 vertical flammability test method because its results are very similar to real fabric burning behavior and it is more responsive than other test methods. Finally, experimental results are evaluated according to a MANOVA analysis using an SPSS statistical program. How and at which level knitted fabric param eters affect a fabric's burning behavior is defined, and regression models of these parameters are obtained. Using these regression models, the burning behavior of knitted fabrics is evaluated, and it is possible to rank them according to their burning character istics.
