Аннотация

Subjects of the research: The ring spinning machine «Zinser», cotton fiber and yarn samples produced from it. Purpose of work: Improve the quality of yarn on the basis of theoretical research and practical and optimization of parameters of ring spinning machine «Zinser». Method of research: Of properties of yarn carried on the researching equipment of certification center named after «CENTEXUZ» at TITLI, also on the modern test equipment installed in the laboratory branch of “Gurlan teks” foreign company “Muruvvat teks”. There are used the theory of mechanics of yarns, methods of mathematical statistics and analysis of the experiment in this thesis. The results obtained and their novelty: The influence of spindle speed and twist on the properties of the yarn was studied. Defined the dominant influence on the properties of the yarn twist, and with increasing number of twist the difference of actual twist increases than nominal. Justified that by changing the size of the triangle of twisting may improve the structure of the yarn and improving its quality. Strain components are estimated with great accuracy using strain created by the test apparatus. Determined that the compact yarn has a higher tensile force compared to the conventional yarn by 14% and hairiness below 80%. Practical value: Based on research of the effect speed spindle and twist on the properties of the yarn recommended optimal operating parameters of high-speed ring spinning machines. Rationale for ways to improve the quality of the actual yarn is of great practical importance. Degree of embed and economic affectivity: The results of the thesis introduced in the spinning machine with 1200 spindles in branch “Gurlan teks” foreign company “Muruvvat teks” and economic efficiency of 43180.35 thousand sum. per year. Field of application: Mills of spinning.
