NATURAL SILK BASED SURGICAL THREADS PRODUCTION TECHNOLOGY EXPLOITATION

Production and processing of natural silk is one of the most complex technological processes in the textile industry. The natural silk goods produced with high sanitary-hygienic and exploitation properties are in great demand in the world and considered to be one of the most valuable among textile merchandises. The Republic of Uzbekistan has got a powerful raw material supply and workout chain. Nevertheless, we have recently felt demand in such materials for surgical purposes. The natural silk, having high bactericidal and hygienically features and high fastness, is an ideal material for surgical threads, where biological complexion of the natural silk determines its compatibility with fabric of organism. For this purposes the thread should have the following properties: Smooth surface, which doesn't impair and without any drawbacks High fastness either in wet and dry condition Good perception towards wet-heating treatment when it is sterilized Capability to retain its sterility for along period of storing Low irregularity Absence of oil and filthy spots. Complying of the above listed features in stitch materials is possible when: an important mixture of raw materials is selected; the following defects such as knobs, mossiestion and oil spots are not allowed. The technology of production of the surgical threads from natural silk has recently been established and examined by the group of scientists of the Tashkent institute of textile and light industry for the production of diverse surgical threads. This method of extraction of the surgical thread has obtained a positive result from national patent agency. An experimental portion of the produced surgical threads was sterilized and has been tested in clinical conditions through several hospitals. The Ministry of healthcare of the Republic of Uzbekistan has given a certificate, which gives a license to produce and application of the surgical threads from the natural silk in medicine.
