OPTIMIZATION OF THE WEAVING PROCESS IN THE PRODUCTION OF HEAVY FABRIC

Abstract

A preliminary study of the object of research showed that the goal of optimizing the weaving process is to achieve the maximum level of equipment productivity. Reducing the level of thread breakage in the weaving process to the greatest extent (at a constant speed of the main shaft of the loom) contributes to achieving this goal. This allows it possible to select a minimum of warp end breaks as the main criterion for optimizing the weaving process. On the one hand, it defines indicators such as weaver's workload, equipment utilization rate, which significantly affect the productivity of labor and equipment.    On the other hand, the indicator of the thread breakage can be unambiguously defined the conditions of fabric formation on the loom, depending on technological parameters of its filling and set at a minimum value of thread breakage, the most favorable conditions of fabric formation. Thus, adopted criterion of optimization allows characterizing effectiveness of research object with the highest degree of completeness. During production of heavy fabrics for minimal thread breakage it is recommended to set the following optimal parameters: warp tension 60 cN (per thread); cloth fell position - 10 mm; the position of the back rest relative to front rest - (+ 10) mm.
