ABSTRACT The purpose of this research comparison property fiber processed in various cotton primary processing factories with different models of gins. Each sample of 1st grade С6524 of cotton raw has been subdivided to process factory gins of Namangan area. Properties of the Fiber of all samples have been measured with the Advanced Information System of Fiber HVI, for definition of an exit of average length fiber UHM (UHML). АННОТАЦИЯ Целью данного исследования является сравнение свойств волокна, перерабатываемого на различных фабри- ках первичной переработки хлопка сырца с различными моделями волокноотделительных машин. Каждый обра- зец хлопка-сырца 1-го сорта С6524 разделен на переработку на заводах с различными видами волокноотделитель- ных машин Наманганской области. Свойства Волокна всех образцов были измерены с помощью Advanced Infor- mation System of Fiber HVI, для определения выхода волокна средней длины UHM (UHML).

Keywords: Gin, The exit of average length fiber UHM(UHML); statistical analysis. Ключевые слова: Джин, выход волокна средней длины UHM (UHML), статистический анализ. ______

Introduction strength, and trash content that are important in textile Globally, cotton fibers for sale are selected and processing. Fiber quality is an important aspect of cotton measured in accordance with (HVI) standards. Fiber research and the fiber must be removed from the seed standards (HVI) are set by ‘SIFAT’ enterprise to define to determine its bulkiness. fiber properties such as color, length, micronaire, ______Bibliographic description: Azizov S.M., Muhammadjonov M.

The purpose of our study was to compare the quality for cotton researchers predicting fiber quality in produc- of the fiber and to analyze the cotton factories of the Na- tion gins [1], [2]. mangan region with different types of gins and their Methods working parts that contribute to the yield of medium fi- ber length. Hereby, to determine the optimal parameters of Hence, using these data, we have determined the the working parts of the gin for modeling the quality of way of conducting the research. To begin with, we have the fiber. The fundamental basis for our research was a carried out a statistical analysis, having received data study conducted by American scientists, in regard to a from the ‘SIFAT’ enterprise for cotton fiber of the first comparing factory and laboratory gins, since the differ- grade C6524 of the harvest of first year of research, sec- ences between laboratory gins and production gins have ond year of research, third year of research, hence the not been studied. Thus, their research has shown that the main indicator we have taken was the average yield of results obtained from the gins of the laboratory cannot the long fiber. It is marked as UHM (UHML) - the upper be accurately reproduced, even with a correction factor, as well as average fiber length, which characterizes by while in the production of gins in cotton processing the average length of half, approximately 50% by the plants [1], [2].
