| Abstract: | The
present study is aimed at imparting polyfunctional finishes on 100% cotton
fabrics using polycarboxylic acids (PCAs) that are capable of crosslinking with
cellulose. Polycarboxylic acids, such as maleic acid, itaconic acid, citric
acid and tartaric acid, have been selected and applied in single and in
combinations on 100% cotton fabrics using pad- dry- cure process. PCAs treated
samples are then tested for functional properties as per international standards.
The crease recovery behaviour of these samples has been found to improve almost
to the same extent and in some cases more than that of resin treated control
sample. However, the strength loss is found to be lower for polycarboxylic
acids treated samples. Flexural rigidity is also recorded very low. Soil
release properties are improved by this treatment to attain the maximum grade
of
5 from grade 3 for untreated sample. Reduction in dimensional changes is found
negligible. Formation of ester crosslinks between cellulose and polycarboxylic
acids has been confirmed through FTIR spectroscopic studies. It is found that
the PCAs selected for the study could impart multiple functional properties on
cotton. When applied in single, maleic acid and itaconic acid provide better
results than the other two PCAs, whereas in combination, citric acid with other
PCAs provides synergic effect in imparting functional properties. |
