Waste recycling in spinning mills – a value addition

Efficient use of natural resources and utilisation
of recoverable wastes are getting more and more important day by day since recovering
wastes have both economic and environmental benefits. As the source material
costs constitute the majority of the yarn production costs, decreasing raw
material costs provide considerable advantages for spinners. From the point of
textile manufacturing, various production wastes can be reused in textile
industry. In this study, different waste types in spinning (card waste, blow
room waste, and fabric waste) and blending ratios were used. The effect of
waste type and blend ratio on the physical and mechanical properties of the
yarns and the fabrics, produced with virgin and waste cotton fibres, were
analysed.

Textile wastes can be divided into two main
groups: production wastes and post-production wastes. Production wastes are
basically raw materials of each production step which cannot be put into end
product due to different reasons. For yarn spinners, these wastes can occur
during cleaning fibres or combing out short-staple fibres from the long ones in
a combing machine. These clean/unclean wastes in fibre form or not, can be
reused. After spinning mill, there are wastes in yarn and fabric forms, and
they need recycling to be put again in productio
