Abstract
The research was conducted during 2009-2011 with the objective to study the
impact of laundering on physical parameters of five knit samples each printed with
different media. 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.
