Preparation of Synthetic Stones for Denim ...

Abstract- Synthetic stones have been prepared with different chemical compositions selected statistically using Box and Behnken model. The Linear regression analysis figures have been obtained using MATLAB to evaluate the extent of modification in recipes on the basis of hardness. The Mohs hardness scale has been used to evaluate the hardness of stones. Various properties of the synthesized stones were evaluated. The effects of synthetic and natural pumice stones on denim washing were compared. The washing was done in presence and absence of various fading agents and cellulase enzyme. A particular composition of stone was found to give the best result. Synthesized stone is found to be a better substitute to natural pumice stones.
