The physical and dimensional characteristics,i.e. course and wale spacing, stitch
density, tightness factor, diameter, porosity, dimensional stability and
bursting strength of single jersey knitted items containing lycra yarn with the
variations in stitch length and lycra content have been examined and a detail
investigation on the lycra filament has been discussed in this study. Six
different samples were knitted with identical cotton and lycra yarn but
different in lycra contents and stitch length. After conditioning in a
controlled environment, all the samples were tested as per the established
methods. After analyzing the test results, noticeable effects of variations in
stitch length and lycra content on physical and dimensional characteristics of
single jersey knitted fabric has been found. As smaller the stitch length and
as greater the lycra content, the dimensional stability and bursting strength
are better; on the
other hand, the
air permeability is lower.
