Investigation of the use of hemp fibers in recycling spinning

Abstract

In recycle yarn spinning, the original fibers are added to the blend as a carrier because of the recycled fibers obtained by opening from fabric scraps are very short and coarse. In the textile recycling industry, mostly petroleum-based synthetic fibers are used as carrier fibers. In an environmentally important activity such as recycling spinning, it is necessary to reduce the use of synthetics used as carrier fibers. When considered from this point of view, hemp fibers come to the fore with their important performance and environmental features. Based on this fact, in this study, in addition to the standard production conditions in the recycling yarn production facility, hemp fibers in different proportions were added to the blends to reduce the ratio of polyester as carrier fiber and the effects of this situation on yarn quality were examined. According to the results, it was observed that adding hemp fiber to the recycle yarn blend increased yarn tenacity, yarn unevenness and yarn hairiness while decreased yarn elongation properties.
