Measurement of Fabric-Take down Force on Double-Bed Circular Knitting Machines

On a double-bed circular knitting machine with a needle bed diameter of 8e˝ (200 mm), and machine gauge of E17, which knitted with 8 knitting systems, rib fabrics in basic construction were made. The machine is used to knit cotton knitted fabrics to be used for making children's clothing, especially undershirts and undergarments. Yarns counts from 12 to 36 tex can be used for knitting on the machine. Fabric samples were made from single cotton yarns in counts 16, 20, 24 and 30 tex. When making fabric samples, the optimum machine control for 20 tex yarns was applied. From each yarn 5 samples approximately 2 m long were made and fabric take down force was measured for each sample. When the fabric was removed from the knitting machine, fabric-take down force was measured in different ways. When making samples from finer yarns, average fabric-take down force amounted to 15.1 cN/needle, and when using coarser yarns it amounted to 22.9 cN/needle. Different measuring conditions provide essentially different average tensile forces for fabric-take down force.
