STUDY REGARDING YARN TENSION DURING KNITTING ON CIRCULAR MACHINE WITH SMALL DIAMETER

Abstract

If yarn tension is controlled properly during knitting, it gives an improved and uniform fabric appearance. The main objective of knitters is to feed yarn to the knitting point at a low and uniform tension. To ensure that the stress do not affect yarn properties, literature recommends that the yarn tension shall be so adjusted that it fits in the field elastic. The value of the yarn stress influences not only quality of knitted product, but also the value of the knitting machine production, by the frequency rupture of yarns. This is influenced directly by the yarn stress and yarn quality. The value of this tension is influenced by a complex of factors, such as: technological diagram of the routing of the yarn from coils up to the knitting area, the structure and characteristics of the raw materials, the typo of knitting, type supply, etc. In the present article, using practical method, we test some ecological yarns used to make sock, like cotton, organic cotton, bambooviscose, Tencel, according to 6 different fabric geometry: single jersey, plated single jersey, ribb 4:2, plated ribb 4:2, purl, plated purl. Was enregistered and discussed the values of yarn tension.
