Fabric structure related to weft knitting is

The wale constant and course constant are 4.2 and 5.04 respectively. If the loop length is 4.2 mm, then stitch density (number/cm²) is

If the linear density (tex) of a yarn is doubled, then percentage increase in tightness factor of single jersey knitted fabric (rounded off to 1 decimal place)...
