Аннотация

Subjects of the research: The unreeling raw silk 2,33 and 3,23 tex from cocoons of hybrids of a silkworm Uzbekistan-6 and Chinese, new structural silk braiding surgical threads. Purpose of work: To develop manufacture of a braiding surgical thread of new structure and to investigate their properties. Method of research: Experimental researches were carried out on the modern equipment and chair devices «Technology of silk» and in laboratory "CENTEXUZ" TITLL In job methods of mathematical statistics and the experiment analysis were used. The results obtained and their novelty: The technology manufacture of braiding surgical threads from natural silk is developed. (Patent UZ IAP №0407820) Technological process is reduced to 3 stages, than by manufacture of twisted surgical threads. Speed of unreeling within 115 m/mincs for reception of the raw materials intended for weaving of surgical threads is established. The weaving factor which is recommended for use in formulas of calculation of durability and linear density of braiding surgical threads is proved. Practical value: At use of braiding threads at surgical operations in quality suture material shift cases twist, taking place arc excluded at application of twisted threads. Technology introduction in industrial to manufacture raises efficiency and expands assortment of products. Degree of embed and economic effectivity: Braiding surgical silk threads arc introduced in surgical practice Republican centre of scientific of emergency medical aid MH RUZ. The technology of reception of braiding threads is introduced in manufacture «XON TEKSTIL» LTD. By manufacture and realisation of braiding surgical threads of 10 kg economic efficiency makes 4300 thousand sum. Field of application: In medical establishment and on silk processing factories.
