The course follows the basic subject Textile Technology I. In this course, students will improve knowledge of the yarn manufacturing. There are discussed individual technological stages of the yarn (opening, cleaning, blending, carding, doubling and drawing, combing, converter technology, roving production, ring spinning, rotor spinning, air jet spining and twisting). Selected unconventional yarns are mentioned. The influence of individual technological levels on the properties of the final product is briefly analyzed. It is refered to the selected basic technological parameters of the machines and their influence on the quality of the final product.
