In this study, we re-create the 100% sustainable denim fabric from recyled textile waste fibers and developed by combining waterless processes and ozone use, ecological rinsing processes in the finishing and indigo dyeing processes. In addition, the elastane yarns used were also from sustainable sources.

Up to 100 billion garments are produced by the fashion industry every year. Therefore, reduce the environmental impact of textile industry and produce more sustainable fashion is a very important concept for the future of the world. In particular, it is important to bring cotton fiber, which has a higher comfort feature than synthetic fibers, to users with sustainable processes and to reintroduce it to the circular economy.
The results of fully sustainable studies in the field of denim, which also has a large place among cotton products, will provide great gains on a global scale in reducing environmental impacts.
In this study, we re-create the 100% sustainable denim fabric from recyled textile waste fibers and developed by combining waterless processes and ozone use, ecological rinsing processes in the finishing and indigo dyeing processes. In addition, the elastane yarns used were also from sustainable sources. In order for textile wastes to be used in conventional yarn and fabric production in the future, the recyling processes must be done without harming the fiber quality. After this process, the length of the fiber components, % of short fiber, homogeneous distribution and purity of the fiber are the most important steps that determine the structure of the yarn and fabric. For this purpose, in order to produce 100% Recycled
Cotton yarn from fibers obtained from pre-consumer wastes of cotton origin, fabric production is carried out with yarns that can be used in warp and weft, with more hairless and higher strength values, with the new methods we have developed in spinning geometry.
