Woven products are made from natural silk, as well as various artificial, synthetic and glass fiber threads. Woven threads, depending on their structure and structure, require the use of technology, machines and mechanisms, depending on the quality of the raw materials and the intended production of the product. In silk weaving, in addition to purely mechanical processes, i.e. rewinding, weaving and re-weaving, chemical technology is also used, i.e. cooking silk raw materials, dyeing the thread and other processes. In most cases, both mechanical and chemical processes are used in silk weaving technology. Intermittent machines, chillers, centrifuges, drying machines, steaming chambers, and khakazos are used in the production of Eshish products, as well as re- wrapping and continuous operations are used. The silk production technology course is one of the main sections of the "Silk Technology" special course program for students of textile higher education institutions. This textbook explains the technological processes of production of raw silk from dry cocoons, production of woven natural fibers and spun yarns from chemical fibers, and the theoretical basis of silk production technology. New assortments and knitted dresses are being created for the development of fabrics mixed with raw silk and other fibers. In addition, taking into account the properties of natural silk, pure silk sheets, socks, surgical and sewing threads are being developed. Currently, sewing thread is widely used in industry as finishing for special purposes, as well as fire-resistant, biocidal, aromatic, light-reflecting and other materials. As can be seen from the picture, sewing threads are natural, chemical and mixed (from chemical and natural components) according to their raw material composition. The dashed line shows our new range of woven and braided yarns. According to the finishing method, sewing threads can be raw, dull, shiny, shiny, white, black and colored. In the production of fabrics, knitwear and non-woven fabrics, 3-ply single-ply and 6-ply double- ply sewing threads are widely used. For sewing threads such as woven spun thread, the matching direction of sewing and the weight of the thread are of great importance. The |
