The object of the research work: libit-warping machine, warping drum li bity, abvrband machine, warp and weft looms, the national fabric of the «Khan Atlas»,«dras», «Beqasam». Scientific novelty of the research is as follows: it established that the cause of uneven yarn tension in the process of devel oping Avrova fabric on the loom is the non-uniformity of the tension warp yarns for libita width; it developed a new method of technology for the national awr fabric with de sired properties and structures; experimentally proved the geometric shape of the section lapping-ki libita yarn wound on the warping drum and analytically determined amount of filament winding; developed and theoretically justified libit-warping drum aligns the yarn ten sion libita; apparatus for binding surface libita, to provide a predetermined tension Avrova thread and an electronic SET Single registration for the value of the thread tension. Theoretically determined the specific density of the winding process and parameters avrbandnogo optimized eliminated fault «Nalёzhka» in the fabric; developed new structures Avrova tissue, a method of producing pile fabrics, knitted fabrics receive Avrova way to warp knitting machine; the optimal technological parameters of weaving process, allowing reduction in breakage and improving the quality of fabrics «Khan-Atlas». Implement of the research results: On the basis of results of the made re searches on оptimization of the technological processes and parameters for manu facture of the national аvrova fabrics рresented following conclusions: As a result of analysis of research studies on the deformation, tension and causes breakage warp when developing Avrova fabrics revealed that one reason for the increased value thereof is unevenness thread tension for libit width. Geometric shape and winding yarn wound on the warping drum, and calcu lations obtained numerical values of their parameters. The model libit-warping machine to determine the size libit go warping method. In order to align the length and tension of warp threads in libit, improve the quality of national Avrova fabrics is recommended to use the new warping drum. Creating a model avrbanding machine to determine the size of the process piping libit Avrova threads. A device Strapping libit Avrova thread surface as a result of eliminated fault «Nalezhka» in the fabric. 53 Developed analytical calculation method, describing the motion of the hed dle, taking into account the stiffness coefficient of the warp, elastic element heald frame healds and weight, can be used: -technological optimizing the manufacturing process the fabric different pat terns to reduce deformation and breakage warp; -for calculating weaving machine parameters in order to obtain predeter mined fabrics structures and properties. Development of new kinds of structures and fabrics Avrova allowing ex pansion of asso
