Abstract:
In order to obtain ideal warp tension dynamics, by regulating the tension spring and its tightness settings, based on investigations carried ort on the dynamics od yarn tension during the knitting process, analysis of the warp tension patterns under different compensations, as well as a study of the operation mechanism of the compensation device was carried out. Results show that the use of tension compensation device can compensate for yarn tension fluctuation. However, with the increase in the elasticity coefficient of the compensation device, the peak value of yarn dynamic tension also increases leading to excessie yarn tension variation resulting in yarn breakages which in turns asversely impacts production efficiency. However, it cannot be taken that the lower the elasticity coefficiency the better, as lower yarn tension leads to volatility in yarn tension, leading to peoduction defects such as drop stitches on fabric surfaces. The elastic coefficient of an ideal compensation device, therefore, needs optimum adjustment to ensure efficient production.
Key words: warp knitting, yarn tension compensator, warp fension, dynamic tension, elastic coefficiency
