Abstract:

Based on the significant influence of warp tension on warp knitting production, the KARL MAYER type warp knitting machine was used to carry out the experiments. Firstly, the elasticity coefficient of elastic element for the compensation device was tested, and then three groups of tension spring installation density and tension spring specifications were selected, the warp tension test experiments were carried out by changing the elastic coefficient. The experiment data analysis shows that by changing the tension compensation device related parameters, the slastic properties of compensation device could be changed, which can adjust the compensation on warp knitting tension. The results show that the maximum dynamic tension of warp increases with the elasticity coefficient of tension compensation device, and the minimum value first increases then decreases. The average dynamic tension of warp rises, and the variation coefficient increases. This indicates that with the elastic coefficient increase of tension compensation device, the compensation effects decreases.

Key words: warp knitting, tension, tension compensation device
