Abstract
In the course of the research, the influence and the multiplicity of treatment of the same batches of wastes on the content of scutch, the quality of short fiber was studied and the optimum physical and mechanical parameters of their processing were determined in separate sections of the curing machine. For this purpose, we carried out a deep analysis of the operation of individual units of the tow scutcher flax unit. The physical and mechanical parameters of various options for treating wastes on the unit are given. Output characteristics of research options were set by the maximum and minimum frequency of rotation of the scutching drums, which can be obtained on the basis of the mechanical and design features of the unit. The correlation analysis of the physical and mechanical parameters of the treatment of scraping waste on the tow scutcher flax unit carried out with various processing options showed that the processing parameters have a slight effect on the strength of the fiber and on the percentage of bromegrass in it. The physical and mechanical parameters indicators of the quality of the short fiber after multiple treatments on the preparation unit were investigated. For a more in-depth determination of the impact of scutching waste treatment on the spinning properties of short fibers, pilot batches were processed into yarn. Analysis of the processing parameters of short flax fiber for tow scutcher flax unit in combination with the physical and mechanical parameters of the yarn showed that there is a quantitative correlation between the breakage of yarn obtained from different fiber options and the operating modes of the unit. The range of processing parameters corresponding to the number of 95...105 mechanical effects at which the fiber is most suitable for spinning is determined. It has been established that improving the quality of short fiber should be carried out not at the expense of additional energy and material costs, but through the development of new resource-saving technology for processing low-grade raw materials on modern equipment of processing companies. The prospect of further research is the development of technology for producing high-quality short fiber from scrapping wastes and low-grade trusts, which will ensure maximum removal of bromegrass and preserve strength, since it is these output characteristics of short fibers that determine its suitability for further use.
