Investigation of the use of hemp fibers in recycling spinning

Acta Scientiarum: Technology, 2023
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
