LyzerContra DS

(Discharging agent for disperse dyestuff.)

Lyzercontra DS is a versatile chemical offered in paste form and appears off white to pale yellow in colour. It is recommended to obtain multicolour effects on polyester or polyester containing fabrics as well as to obtain clean white prints on polyester containing fabrics.
Lyzercontra DS prevents the development of selected disperse dyestuff on polyester fabric thereby facilitating white printed effects. However, by using selective combination of disperse dyestuff it is possible to obtain bright coloured patterns, the coloured portions appearing much brighter in tone than other similar chemicals in the market. Depending upon the depth of the ground shade as well as method of dyeing the concentration of Lyzercontra DS ranges from 5 to 15%.

For colour discharge the requisite quantity of non-dischargeable dyestuff is used in the print paste recommended for white discharge, the ground colour being dischargeable. The recipe given for colour discharge is used for fully dyed goods, whereas in case of fabrics merely padded with disperse dyestuff, the conc. of Lyzercontra DS may be reduced by about 50% depending on the depth of ground shade. The fixation process is completed by pressure steaming at 25 to 30 lb/sq. in at 130 deg cen. For 25 to 30 minutes. Alternately it can also be fixed by high temperature steaming at 170 deg cen. For about 7-10 minutes.
The steamed fabric is subsequently reduction cleared with 2gpl of caustic soda and 2gpl of sodium hydro sulphite at 80 deg cen. for 15-20 minutes to remove unfixed dyestuff as well as to improve the brightness of the prints. Finally the goods are given a thorough soaping to remove all extraneous matter.

STORAGE: The product enjoys very good shelf life and warrants no particular storage conditions. However it is always advisable to have moderate conditions with the container being recapped tightly after use. 9 to 12 months if stored below 30c

30 , 50 in Plastic Container.
According to our best knowledge and technical experiments, the above data is true and accurate. Regarding to variety of consumption procedures, it is recommended to evaluate the information before use.
