Abstract:
Good preparation on textile materials
is very much needed for successful coloration.
Natural or synthetic chemicals in the fibres can
interfere with wetting and dyeing performance.
Hence preparation is the series of processes used
to remove these chemicals for the effective
coloration and finishing of textile materials. By
the good preparation of a material it is possible
to produce an even and regular colour on the
material with facing least difficulties. The aim of
this paper is to determine the weight loss
percentage after bleaching of different cellulose
fabrics with various bleaching agents. For this
investigation commercially available three types
of cellulose fabrics such as plain weave, single
jersey and (1x1) rib have been chosen. Weights of
these fabrics were calculated before and after
bleaching with two different bleaching agents
such as sodium hypochlorite and hydrogen per
oxide. From the weight variations, weight loss
percentages of these three fabrics have been
calculated and after the completion of this
investigation weight loss percentages were found
to be less after using hydrogen peroxide as
compared to sodium hypochlorite.
