In this study, plain fabrics were produced from yarns obtained from cotton fibers and recycled cotton fibers obtained from yarn waste. Within the scope of the study, yarns with cotton/recycled cotton fiber ratios of 100-0%, 90-10%, 80%-20%, 70-30%, 60-40% were used. All fabrics were subjected to finishing processes respectively under the same conditions. Breaking strength and tear strength tests were carried out to understand the effect of the recycling rate on the strength loss in fabrics. In the research, important findings were reached regarding these fabrics. It was determined that there was a decrease of nearly 45% in the tear strength of fabrics obtained by mixing 40% recycled fiber. Additionally, the loss in tensile strength was less than the loss in tear strength.
