Various articles of PVC namely Surfer (size 8); Angola (size 8); Stiff(size 8); Angola (size 8); Stiff9size 8) and Celery (size 8) were studied for their lustiness, softness, compatibility, weight, sole length, hardness Shore A, cup depth, sole thickness, heal thickness and cell structures. Methocell of cellulosic nature was employed for improving these quality parameters for regular production at the shop floor. The methocell was used in the dosages of 0.150 Kg of overall batch size of 58 Kg. The results were quite interesting when the soles were evaluated in the quality control laboratory. Methocell F 50 specifically imparted the best quality to the soles. Since it was of cellulosic nature hence the soles were quite flexible and most competent at the European and Foreign wearing conditions. The 20 station machine operation with this formulation was found to give satisfactory yield of the soles. These articles are basically cheap in their selling price and hence manufactured in large volume.
