The Effect of Blending Composition against Latched Power and the Resistance of Batik Wax against Cracking and Alkaline Chemicals

On this research has been done the optimization of the batik wax waste utilization through batik wax making with blending method using bees wax, gum rosin, paraffin and lard. This research has been expected to be able to reduce the water pollution along with the decline in the quantity of batik solid waste which has been discharged into water bodies. However, research needs to be done regarding the quality of batik product resulting from a production process using wax which involves the use of batik wax waste. The batik product quality is determined by latched power, and the resistance of the wax against cracking and alkaline chemicals of batik wax product which has been used. The latched power test results from four groups of batik wax product showed the area with minimum latched power on temperature range of 50-70 ËšC for batik wax which have been made from blending of bees wax, wax waste, and gum rosin, 50-80 ËšC for batik wax which have been made from blending of bees wax, wax waste, and paraffin;  50-90 ËšC for batik wax which have been made from blending of bees wax, gum rosin and lard. Compared with wax product which have been made from blend of bees wax, wax waste and gum rosin as well as with paraffin, the batik wax product which have been made from the blend of bees wax, gum rosin and lard have lower resistance to cracking that has been observed from the occurance of yellow color on the fabric sample resulted from the dyeing process using yellow naphtol. The different result has been obtained from resistance test of the wax product against alkaline chemicals which showed that all kind of batik wax product resulted on this research have a good resistance against alkaline chemicals which has been observed from the absence of wax mass reduction of the fabric samples before and after treatment in the alkaline chemicals.
