Steam is now widely used reactive dye printing process of fixation. “A phase” Print Print dough by adding a certain amount of domestic demand, alkali, urea and other additives, pressure immediately after binding to the steam drying. The adoption of the “first phase” printing process has a variety of models for the type of flower, which outlines clear pattern, color and so easy to grasp.

When printing paste to Be an alkali, not only the resulting hydrolyzed reactive dyes and the viscosity of the slurry of sodium alginate decreased also strong, which should lead to instability of the print quality, it used to be companies low reactive dyes and strengthen the range of steam, fixing and washing. Also, because printing paste with the addition of alkalis, textile printing needs immediately after the fixation with the process of treatment, otherwise the process of wind in India to keep defects, etc. produced.

“phase” of the pressure of these disadvantages is reactive “phase two” printing process now renewed understanding of it.

“phase two” reactive dyes
A “two phases” printing paste printing process is not necessary to attach the alkaline agent, and the use of printing and coating technologies alkaline treatment. As the alkaline agent is not printing color paste, pressure immediately after fixation and without treatment, would be a process of the shelves in India not so mixed wind. Dyes can also be configured to provide a stable time they would not dye hydrolysis. Reactive “phase two” printing process, short fixation with steam, steam ended the savings, soaping Lase least, bright, good color rendering and good reproducibility.

“phase two” printing process, despite these advantages, however, Joseph is still not widespread, the most important reason is that alkaline padding of technical constraints. For cars General slippery fluid of 70 ~ 80% as very low, and if the use of the car, the “two phases” of the printing process of fixing alkali leaching fully requires not only a lot of additives, and about the need re-roll impregnated tissue. As the substance is not fixing the dye in the alkali-impregnation at the start in large numbers in the soaking solution collapse, which can see colors and patterns on the murky outline of the poor print production we do, we should adopt the “two phases” printing process that rolling, rolling alkaline liquid vehicle is in special conditions have low stock in order to ensure that the dye is not removed from the rolling base fabric.

With the weak stock selection method for solving the “right of two phases,” in the problems of production storage releases alkali

GOLLER Germany company, we are using low to medium to cart reactive “phase two” of print production have rolled alkali treatment and achieved satisfactory results.

Figure 2, the work of a small amount of liquid machine diagram
1 -. cover stains roll, 2 – the liquid scraper, 3 – Magnets, 4 – granted quota worst, 5 – to own devices; layer of tissue – - 7, 6 stack roller 8 – measured in the liquid layer, 9 – do not measure the liquid layer 10 – Roll control

Can in Figure 2, “to see small amount of fluid machinery.” tissue in the tissue with a high office in the lower support unit order the fluidity of the fabric, with stainless steel and actinide roll a roll tissue expanders are equipped. Turn the unit includes a stainless steel train, the storage medium is very limited, there is a layer of rubber coated roller impregnated.

there is a circle with a liquid core scraper, using a bar magnet, so that pressing the surface of the roller blade impregnated.

behind the scraper, spread the liquid in a thin layer of very thin, the distribution of impregnated role in the thickness of the liquid surface to scratch the surface of the decision surface of the neck. Overlaid with a roll of pressure control fluid pressure to the fabric.

edit distance between the base blade and the magnetic strip, the molding pressure liquid pig round will be adjusted. Under normal circumstances, maintain a distance of 2 ~ 6 mm square. Set the level when the device is used to adjust the worm or replaced with different surfaces of the leaf.

GOLLER company does as a low turnover, a vehicle with less than 3O% yield of liquid filling, access to printed materials not dissolved dyes fabric softener, and it could be more reactive “phase two” of his trial pressure applied. can save with a normal trolley compared to 50% soaking solution, and the use of hair color cape more thin, it will not result in the infiltration. As the tissues are less liquid and therefore pressure wash the burden of treatment smaller, easily.
