TOOLS TO DETERMINE THE TENSION OF SELECTED YARNS ON KNITTING MACHINES BY EXPERIMENT

The article examines the tools and equipment for measuring the tension of yarn on looms. Tension gauges manufactured by various firms have also been researched. The study and experimental determination of the tension of yarns in looms on looms allow not only to find the amount of tension but also to find its vibrational nature, as well as changes in various parameters during the weaving process. Experimental study of tension allows to determine changes in yarn tension in the width and depth of the machine, to find the causes of various diseases in the fabric, to find a way to improve the quality of the fabric and increase the productivity of the machine. This will play an important role in the processing of yarns from chemical fibres. Yarn tension measuring tools can be divided into classes and groups according to certain characteristics. In weaving looms, in the practice of measuring the tension of yarns in the body, the electric, mechanical and optical movements of first-class tools are common. НН-2 (Figure 1) branded tool for measuring the tension of individual yarns. The yarn tension in the instrument is determined in grams and is indicated by an arrow on a scale in the measuring range from 1 to 400g. As can be seen from Figure 1, the tool has two handrails and sliding support: a guide and a receiver, a rotating thread.
