The influence of various portion of cotton waste and way of cleaning on quality of open-end rotor yarns

Original language description

Nowadays, recycling and reuse of natural resources has become an important topic. The adaptation of technological lines is crucial for the production of yarn from recovered or reclaimed waste fibers with lower length and possible higher contamination. The way of cleaning is a key factor of waste fibre processing into yarn repeatedly. This study is oriented to the investigation of open-end rotor yarn quality in gray and dyed form, which were spun from various portions of cotton waste from 0% to 100% on R37 Rieter spinning machine with exchangeable cleaning channels. The standard cleaning channel C is complemented by two others. The cleaning channel A is suitable for processing of cotton waste, when the amount of impurities in the raw fibrous material is low and the high quality of final yarn is requested. The maximisation of fiber yields predominating on removing impurities and reducing the generation of waste during spinning is the philosophy of innovative way of cleaning W. The standard quality indicators of fibers and yarns were measured. The generalised analysis of variance were used to prove whether the quality of yarn is significantly influenced by selected predictors (quality of fibers, state of yarn, way of cleaning and level of twist). The experiment verified that the open-end rotor spun yarn 29.5tex can be produced from the mixture of cotton waste with or without addition of virgin cotton fibers via selection of spinning strategy (way of cleaning) and suitable level of twist. The use of cleaning method W deteriorates some partial yarn quality indicators, but the shift of yarn quality is mostly within the USPTM level for given quality groups of USTER®STATISTICS. Most yarns are at the 6%-25% qualitative level except the yarns produced from 100% waste which is comparable with 51% -75% qualitative level sufficient for selected end use.
