Abstract:

This study aimed to investigate the tensile, bending, comfort properties and burning behaviour of the woven fabrics produced with different blend ratios of meta-aramid and wool yarns. For this purpose, twenty eight woven fabrics were manufactured using Nm 60/1 and Nm 60/2 meta-aramid and Nm 60/1 and Nm 60/2 wool yarns with different blend ratios. The tensile properties, bursting strength, bending rigidity, comfort properties (water vapor permeability, air permeability and thermal conductivity) and burning behaviour of woven fabrics which we manufactured were tested according to the standards and the results obtained were assessed by means of the statistical analysis program. The results from this study indicated that blending ratios, yarn linear densities and weave structures had statistically significant effects on the mechanical, comfort and burning properties of fabrics. The results of this study show that the breaking force and bursting strength and bending rigidty of woven fabrics increases with the increase of the aramid contents of the fabrics. Optimum breaking force, bursting strength, bending rigidity, air permeability, water vapor permability and thermal conductivity values were obtained from the fabrics consisting of 50/50 meta-aramid/wool and 67/33 metaaramid- wool.
