Sinitsina A. The influence of monoecious hemp variety differences on quality of the fibre

Object of research - process of reception of fibrous materials of straw of monoecious hemp of different selection grades. The purpose of research consists in definition of influence of agrotechnical actions and processing on an output and physic-mechanical properties of straw of monoecious a hemp of different grades, as initial material for reception of a high quality fibre. At the decision of tasks in view were guided by the complex approach to object and an object of research and physical-mechanical, chemical-analytical and mathematical methods. Change of physical-mechanical parameters hemp fibres of different grades from contents in it of chemical components is scientifically proved and the mathematical model is made. It is developed recommendations concerning optimization of technology of reception of fibrous materials from straw of monoecious a hemp. They are based on the directed order of selection of initial raw material which includes uses effective for this purpose of a selection grade of monoecious a hemp. It is developed recommendations concerning expansion of volumes of use of effective and economic technology of reception of a high-quality fibre from the certain selection grade of a hemp. Actions for the organization of technological process of reception of high-quality fibrous materials from straw of a hemp which provide are offered: applications of an effective selection grade, use of optimum ways of cultivation with the purpose of increase of physical-mechanical parameters which allows to expand a spectrum of application конопляного raw material. Field - hemp-processing field of agroindustrial complex.
