Burning behavior of aramid and FR viscose blended fabrics

Abstract

Two sets of yarns have been produced on ring spinning system. In the first set, flame-retardant viscose and meta-aramid are blended in three different ratios of 30:70, 50:50 and 70:30, and in the second set, flame-retardant viscose, nylon 66 and meta-aramid are blended in two different ratios of 30:20:50 and 50:20:30 respectively. These yarns are converted in to woven fabrics and evaluated for limiting oxygen, contact heat, radian heat and convective heat indices. One way analysis of variance (ANOVA) has been applied to find out the effect of different fibre blends on various flame and thermal properties. It is observed that there is relationship between fibre contents in the blend and flame and thermal resistant properties.
