Abstract:
This study has been sorted on effect of dyeing in physical characteristics of different type of cotton
knitted fabric. For complete this study we have used pre-treated sample fabric and dyed in lab
dyeing machine. We took multiple samples of four type of fabric. And these are Lycra single
jersey, Single jersey, Single jersey slub, 2×2 Lycra rib. We dyed these fabric sample with same
recipe, same atmospheric condition in light and deep shade. We have measured this samples GSM,
WPI, CPI, Stitch length, Shrinkage, Abrasion resistance before dyeing and after dyeing. This
measuring data we have compared with before dyeing and after dyeing. We saw sometimes this
data increase and sometimes decrease. In the case of GSM, WPI, CPI data is increased after dyeing
process. On the other hand, stitch length is decrease after dyeing. That was happened for after
dyeing fabric makes more compacter because of absorption of dyes and chemicals. In case of
shrinkage, we saw some fabric got expansion and some fabric got contraction. For Abrasion
resistance, we utilized that better construction has better abrasion resistance. Here we investigated
thus characteristics of cotton knitted fabric after dyeing process. This paper tries to find out the
major changes characteristics of cotton knit fabric from before dyeing and after dyeing. Hope this
paper will help those people who are in textile dyeing industry.
