The first, at the reactive anddirect dyeing of cotton and viscon fibre, and the other one, it is used for cleaningresin in water soften units to obtain soft water. While using refined salt for reactivedyeing process, rock salt or washed salt can be used at the water soften units.Cost of the refined salt is 1,5 multiple as the rock salt. According to capacityof the factory, consumption of refined salt can be 40-50 tons per month. Also, it canbe seemed that the difference of cost is important. By using rock salt, both the cost ofsalt will decrease at the beginning and the salt solution with continuously fixedproperty (hardness, pH) can be added to the dyeing process automatically.Through building the system, it will obtain economy from work capacity,nevertheless obtained pure salt solution will use not only for painting, but also at theresin regeneration, which is used in water soften systems at factories. Consequently,it is anticipated lengthen the lifetime of resin. In addition that, it will provide energysaving for textile factories.In this thesis, instead of using refined salt for dyeing process, which is veryimportant for the cost, it was realized the using of rock salt by computer controlledautomation system and experimental results were given depend on the running timefor being hardness of the solution between 0 and 2 Fr.Keywords: LabVIEW, Rock Salt, Automation, Textile, Painting.
