When dyeing the textile sample dyeing machine, we must pay attention to the control of the water quantity, which is the bath ratio we often say. As one of the three elements of dyeing, it determines the concentration accuracy of the added dyes and additives, and the concentration determines The chemical reaction rate of dyes and auxiliaries.
When the general laboratory is operating, the gray cloth for proofing will be washed with hot water first. Then, when calculating the required amount of water, the amount of water contained in the grey cloth should be calculated, for example, a 10g cloth sample is called, and it is put into the dye cup. The weight of the former water, then minus 10g is the amount of water carried.
Many people think that the amount of water in each sample belt is the same. In fact, it is generally necessary to put the water-containing cloth into the dyeing cup. The different types of proofers have different hand strengths, and the final water content is different. 10g The swatches, according to the bath ratio of 1:10, each difference of 1g of water, the error is 1%. At the same time, the moisture content of different grey fabrics and different pretreatment processes is also different. When the textile sample dyeing machine is subjected to water washing and other operations, the bath ratio should be avoided so as not to cause the equipment to fail to achieve the desired dyeing effect.
