Abstract
The present study entitled “Efficiency of sizing materials on cottons” was
carried out in 2010-12 at Dharwad with the objectives, to study the effect of sized and
hand washing on physical parameters. The study consisted of survey and experimental
procedure. On the basis of the survey results, two sizing materials one each from
arrowroot and revive were selected for the present study.
Cotton muslin suitable for sari having 70 ends x 60 picks per inch with 34.80
GSM was selected and starched separately with 10% concentration of each arrowroot
and revive with 1:1 and 1:2 dilution levels and were assessed for various physical
parameters. Further samples were hand washed to assess its impact on these physical
parameters, visual appearance and tactile properties. There was increase in physical
parameters when sized with both arrowroot and revive. The stiffness was greater at
1:1 dilution than 1:2 because of higher concentration of sizing solution that deposited
mechanically on the fabric surface. The chromatic and geometric attributes improved
when sized at 1:1 than 1:2 dilution. But there was no change in luster, cloudy
appearance and visibility yarn directionality at 1:2 dilution because of low viscosity
and starch strength. The fabric texture became rough, hard and crisp on sizing at 1:1
dilution level than 1:2. Greater patchy effect was observed with arrowroot than revive
because of larger starch particles and viscosity.
Improvements in physical parameters attained temporarily on sizing were lost
some extent after first hand washing due to gradual softness and pliability imparted on
partial desizing. The sized clothes can be used after one wash, a means to ‘cutting
cost’ starching the clothes. The fabric expressed better stiffening properties at 1:1
dilution of arrowroot than revive 1:1 dilution and 1:2 dilutions.
