The aim of this bachelor thesis was to understand the quality of the yarn in the grey and sized condition. The theoretical part is about defining the basic properties of yarns, which are usually used. Further, these are mapped and described with their chosen method of measurement. In the experimental part, the results are shown from the sub sample properties of yarns from 100% cotton, and then discuss the influence of technological operations sizing on selected properties of these yarns and then a summary to close with the achieved results.Tato...
