A suspension containing SHP additives was prepared by taking
50 ml THF solution containing 1 g copper stearate, 0.25 g PVC and
0.5 g (1 wt.%) iron oxide nano particles and sonicated thoroughly
for 10–15 min. Similarly, instead of iron oxidenano particles, 1%by
weight of chromia nanoparticles (0.5 g) was added separately into
PVC–copper stearate solution in the same proportion prepared
earlier. After thorough sonication (10–15 min), the cotton fabrics
were then soaked for 20 min. The soaked fabrics were later
removed from the mixture and dried in air.
