Порівняльний аналіз роботи нитконатягувачів текстильних машин

Abstract

В роботі наведені результати по визначенню натягу нитки, яка взаємодіє з різними типами нитконатягувачів з урахуванням її реальних фізико-механічних властивостей. При проведенні досліджень використовувалися шайбовий, пальцьовий та модернізований пальцьовий нитконатягувачі. Отримані результати використовувалися для удосконалення технологічних процесів текстильної промисловості.

Presence of breakages of filaments speaks the process equipment imperfection of a design of devices for a filament tension, and it, in turn, leads to idle times of the process equipment and decrease in quality of released products. Research of working conditions of devices for a filament tension allows to design feeding systems of filaments on the modern process equipment taking into account real physicomechanical properties, in particular irregularity of diameter of filaments of their structure and a material. Thus the theme of given paper is actual processes of the textile and knitting industry of great importance for development. Devices for a filament tension are a component of a feeding system of a filament on the process equipment. Development of their design allows to stabilise a filament tension on the process equipment. A theoretical basis at the solution of a scientific and technical problem are works in the field of production engineering of textile and knitted manufactures, materials technology, mechanics of a filament, theory of elasticity, mathematical modelling. In theoretical researches methods of theoretical mechanics, a strength of materials, design of experiments and statistical machining of results of research are used. The gained results allow to develop process of rehash of a filament on the process equipment, to lower quantity of breakages of filaments, to improve quality of finished articles.
