摘要

Experiments have shown that when the clamping length of yarn is reduced from 500 mm, as specified by the standard, to less than 10 mm, its breaking elongation sharply increases. The possibility of predicting the breaking elongation of yarn at a clamping length numerically equal to the height of the stitch row in warp knitted fabric is considered. Summing this characteristic with the maximum elongation of the stitch structure obtained on the basis of Dalidovich model allows the breaking elongation of knitted fabric to be calculated with sufficient accuracy. It is advisable to apply this method when designing technical fabrics that are subject to high loads.
