Since textile waste recycling is a global challenge, there is an emerging need to explore this research direction due to the little knowledge about textile recycling. This study aimed to study the property of yarns produced from recycled textile/cotton fiber blends for proportion optimization and to check whether they can be used for denim fabric production. The properties of recycled fiber and virgin cotton spun on open-end having 4.5 Ne were investigated with fiber proportions of 20/80, 25/75, 30/70, 35/65, 40/60, 45/55, and 50/50. The results were analyzed with Design-Expert software, using central composite design to optimize the proportion. The 40/60 proportion had the optimum result, and by using this optimized proportion, 10 Ne yarn was produced and used for denim fabric production. The sample denim fabric produced used recycled yarn as a weft, showing that the recycled fiber turned yarn can be used in manufacturing products such as denim. The physical properties of the denim fabric confirmed that the recycled goods have wearable quality. Since this research can be applied on an industrial scale, it would benefit textile academia, industry, the environment, and society.
