Subject of research: Ipakchi-2 x Ipakchi-1 cocoons, ultraviolet luminescence, device, raw silk, twisted thread, fabric, knitted fabric, boiling, bleaching. Purpose of work: To improve technology of preparing raw silk for getting uniform silk colouring by sorting according to colour range of cocoons cover. Methods of research: Theoretical research was based on threads mechanics, spectrophotometer method, electronic microscopy, mathematical statistics and experiments analysis. Experimental researches were made using modem equipment and devices at the laboratories of “Silk technology” departments and Certification centre “CcntcxUz” of TITLE The results obtained and their novelty: A device with programmed operating for defining cocoons colour in real time. (Patent №DGU 01345) and atent application (№ FAR 2008 0074) for automated sorting device of cocoons on cover colour range о the base of MKK.-1 were made. Rational speed of unreeling was defined and an application act at the factory on a modern silk reeling machine K.CC-SR100 (115-120m/min) was received. Due to additional including cocoons sorting on colour range the technology of preparing raw silk for making smoothly dyed fabrics, knitted fabrics and goods was improved. Practical value: Rational speed of cocoons unreeling was defined. It will allow to produce raw silk of high quality and to increase assortment of smoothly dyed fabrics which arc in demand both in our country and abroad, it will increase effectiveness of industrial production. Degree of embed and economic effectivity: the research of the dissertation were applied in cocoons unreeling workshop in Namangan “Vodiy ipagi” ltd. Expected profit in manufacture and realization of 1000m2 silk knitted fabric is 406000 sum (in the price of 2006). Field of application: Cocoons unreeling, silk weaving and knitting factories.
