Abstract:
... The carriers are moved along the eight-shaped orbit during braiding, which makes the length of dynamic catenary fluctuate in a certain range. With changing the release speed of carriers, the yarn tension is difficult to maintain stability. The varying tension affects the structure and mechanical properties of the products. In this paper, the calculation of geometrical dimension is carried out for ...
