Dyeing process preparation and optimization
Preparation of dyeing process and optimization of dyeing process of air flow dyeing machine is based on dye dyeing characteristics, so before programming, we must be familiar with the characteristics of dyes used. Each additive must take into account the effect of the additive on the affinity of the dye and the fabric, to determine the addition of the additive, which is mainly based on the influence of salt and alkali on the affinity and directness of the fabric. Each dye has a specific dyeing process, so the dyeing process of the airflow dyeing machine must be tailored to the dye characteristics. In a word, as long as each dye is very well understood, it can be produced quickly and good dyeing process. Depending on the characteristics of the dye, we can be divided into the following categories:
 
1. Some dyes in the sodium sulfate will make the dye and fabric affinity between the increase, we call it salt-controlled dyes, you must control the speed of the Canadian dollar powder, add alkali can be appropriate faster, such as Ciba's FN series, dyeing eight plants of the EF, Korea long spd, ya Yun ee type, and conventional 2GF (or BF), 3BS and 3RS combination of dyes.
 
2, some dyes in soda ash will make the affinity between dyes and grey fabric increased, we call these dyes alkali-controlled dyes, at the time of production, it is necessary to control the speed of soda ash, the Canadian dollar powder can be faster, or add dye before adding back, such as kn black, kn blue, Navy, CIBA S series such as ethylene sulfone is this type.
 
3. If the salt-control and alkali-control of the two dyes mixed together in the dyeing will cause very poor compatibility, is equivalent to produce two times dyeing, if the Canadian dollar and soda powder speed control is very slow, on the one hand dyeing process time will be long, on the other hand, may not do well. In many cases, however, the combination of less compatible dyes is used in order to consider the 1 problem of cost or jump-burn. such as, kn blue (or kn black) and 3BS into brilliant purple, the former is not very sensitive to sodium sulfate, but after adding alkali agent reaction speed, the latter on the sodium sulfate has a certain degree of dependence, but after adding the alkali agent, even in 60 ℃ reaction is still very slow. For this combination of bad compatibility, we can use the pre-add soda process. The so-called pre-alkali, is to add a small amount of alkali before the dye, it can cause a part of the dye to eliminate the reaction and have a lively, and will not cause excessive negative fiber. Pre-alkali dosage is generally about 5% of the total alkali content (depending on the proportion of alkali-controlled dyes).
