Ecological textiles or eco textiles means a recyclable product or a product that can be recycled into an environmentally harmless product which has been produced by paying regard to environment during all process steps from, which does not harm the user. Natural dyeing, which is of great importance in the textiles industry in terms of being economical and applicable, has a number of advantages thanks to its features such as health, ecological cycle and providing biological availability. With the use of natural mordant as a binder during dyeing both dyeing and mordant become important for environmentally friendly processes. This study examines the usability of natural dye extract obtained from Helichrysum Arenarium, which has a wide range around the world, and Quercus Aegilops natural mordant in dyeing of Karabuk Eflani cloth, a regional weaving. Eflani cloth is made from 100% cotton staple. In this study Eflani cloth woven from 100% cotton yarn with Helichrysum Arenarium was dyed with 5 different concentrations of natural mordant. L*a*b* values of the samples of dyed cotton cloth were measured and compared using CIE L*a*b* colour space system. Also, lightfastness and washing features of dyeing were examined. Colour scale was darker and more vivid in dyeing made with Quercus Aegilops natural mordant compared to dyeing made without mordant.

This study aims to design and develop denim fabrics with enhanced mechanical and impact abrasion resistance performance using different materials, yarn types and fabric constructions. It was aimed to reach the standard impact abrasion resistance requirements of motorcycle protective clothing for Level 1 in high impact areas of the body (zones 1 and 2), such as hip and knee areas. The existence of cotton/Cordura® yarn in warp and T400 polyester yarn in the weft and the use of higher yarn densities increased the performance in tensile strength and impact abrasion resistance, compared to a classical cotton denim fabric. The use of coarser yarns and fabrics with a double weave construction increased impact abrasion resistance compared to single layer cloths. The double and backed cloth samples developed with cotton/Cordura® and Kevlar®/polyester yarns in their construction showed impact abrasion resistance times over 4 s and reached the “EN 13595-2:2002 Level 1 abrasion resistance” standard requirement.
