Studies on Estimation of Thickness and Stitch Length of the 3-Stroke Rib Stitch-knit Fabrics

To the present, the stitch length of 3-stroke rib stitch has been calculated on the basis of lapping ratio derived from the needle spacing of plain stitch length. This study is carried out by obtaining a stitch length on the basis of H. Kidacki and E. Dyson's model, which is concerned with unit stitch length and needle spacing as factors. And thickness of 3-stroke rib stitch was calculated through a concept of simple elastica. The results were as follows; 1. The thickness of 3-stroke rib stitch was correlated to t=5D+β'l if non-compressibility of filament yarn was assumed and t"=D' when filament yarn were flattened by compress and flattened about 10%. 2. A stitch length could be calculated from machine gauge when the needle loop length was known and the weight of repeating unit, total run-in and yarn consumption per color etal were estimated exactly. 3. In 3-stroke rib stitch, the fractional stitch length occupied by needle loop was about 40%.
