Abstract


The research work aimed to analyse the surface frictional characteristics of fabric made of different nonconventional fibers like lyocell, bamboo, micro polyester, micro lyocell, bamboo/charcoal, bamboo/cotton and their blends. The fibers were made as fabric in plain weave with different cover factors. The effect of fabric cover on the frictional characteristic was analysed. The result reveals that the increase in cover factor gradually decreases the friction coefficient. With respect to the fiber type and frictional properties, it is found that, the least frictional coefficient value was noticed in the case of pure lyocell. The maximum frictional valued noted in the case of cotton and charcoal blends. The static and dynamic friction coefficient values of different fibers were statistically significant. The friction coefficient values are in the following order for static and dynamic friction repectively; Lyocell < Micro Lyocell = Micro Polyester < Bamboo < Polyester < Bamboo/Cotton < Bamboo / Charcoal and Micro Lyocell < Lyocell < Bamboo < Micro Polyester < Bamboo/Cotton < Polyester < Bamboo / Charcoal. The results also identified that the influence of blend proportion and fabric structure on the frictional properties were also highly significant (p<0.05) as like the fiber content. The plain woven fabric has lowest frictional coefficient values than twill structures. The frictional coefficient values of the fabric structures are in the order of Plain < 2/2 Twill < 1/3 Twill
