Abstract
Topical issues of textile yarn breakage in technological processes are considered in the paper. Based on a comparative analysis of cotton yarns specific breaking load with cotton fibre specific breaking load obtained in experiments, it was concluded that when the yarn breaks, the cotton fibres do not. This conclusion contradicts hypothesis of Aleksey Solov'yov that some of the cotton fibres are torn when the yarn is stretched to a break. Experimental results show that when the yarn is stretched to a break, all cotton fibres slip out of the yarn. So, the main force of resistance to external tensile force is the friction force between the fibres in the yarn. These results require the study of internal forces in the yarn at the meso-structural level. Experimental and theoretical studies of the meso-mechanics of cotton yarn can lead to new technologies for producing textile yarns of higher strength.
