Investigation of the use of hemp fiber in recycling spinning

Raw materials obtained from natural resources have recently attracted great interest in the industry in the world, which has turned to ecological and sustainable production due to the rapid consumption of natural resources, environmental awareness of synthetic production activities and plastic waste problems, and environmental problems on a global scale. All this motivates researchers to develop environmental sustainability concepts to obtain renewable materials and alternative energy. Considering the increasing demand for recyclable and organic textile products, the importance of searching for alternative fibers instead of synthetic fibers is understood. Within such a framework, the use of hemp fibers common in many civilizations represents an interesting example of enriching a natural, ancient resource. Hemp fibers, with their high strength and remarkable properties, have long been used in the manufacture of textiles. For this reason, it is predicted that the use of bast fibers instead of synthetic fibers will provide more benefits both ecologically and economically and will greatly reduce foreign dependency. In this thesis, the use of hemp fibers in recycling spinning has been investigated. Alkaline washing, bleaching and softening processes are applied to mechanically treated fibers to make them workable in open-end spinning. At the end of the process, the spectra of the fibers were taken by FT-IR spectroscopy and their chemical contents were examined. 20 different samples in 4 different numbers were obtained by blending the cottonized fibers with recycled cotton and polyester fibers in certain proportions and in lots. The samples were subjected to certain quality tests and the results showed the suitability of hemp fibers for use in recycling spinning.
