The study consisted of survey and experimental procedure. Interview schedule was administered on thirty each working, nonworking mothers to elicit information on clothing preference, clothing purchasing practice and laundry practices; and readymade shop owners regarding fibre content, branded knitwear and embellishment techniques commonly adopted to knitwear viz., discharge, flock, foil, pigment and plastisol were chosen and subjected for fifteen hand washes by kneading and squeezing. After every fifth wash the samples were assessed for fabric count, thickness, weight, shrinkage and colour of wales and courses per inch, thickness (mm), weight (GSM) but reduction in colour strength of both printed and unprinted areas of all knit samples compared to their corresponding control values after fifth wash. All the knit samples attained dimensional stability before fifth wash. Flock print exhibited very poor colour strength (K/S) values, followed by pigment and plastisol. The percentage of slenderness of print area reflected poor strength, durability, quality and standard of the print media, print style and printing method. It is evident that flock printed knit sample was found to be very poor, since the flock was completely washed off and disappeared by fifteenth wash leaving a part of thickening agent which was held mechanically. Home laundering did affect the physical parameters of both unprinted and printed area of knit samples, as the composition of all the five print media was not similar. Hence, the level of impact of home laundering on physical parameters varied greatly.Thesis
