Digital bottom PulpProduct performance is soft, smooth and non-viscous surface, the effect on the base color is small, stretching does not return white, washing does not return white, the digital base of the special surface coating is not lost, which greatly improves the washing resistance. Machine Washing method: 60°c,2.5 hours, 1200 rpm, one wash, one baking, can be washed 5 times in a row, not bleached, not white, can not be printed on the cover, to improve the dry and wet friction 1-2 third, the completion of the process of digital printing, direct spraying inkjet, and the Flash machine baking for 7 seconds. The M1206 can be covered 3 times with a 100 mesh, and the flash machine can be dried for 7 hours. or bake in 120°c for 2 minutes, then heat the stove in 165°c for 2 minutes to make the ink completely dry and solidify before washing.
Reactive dye dyeing usually requires the addition of alkaline reagents to cellulose molecules under alkaline conditions. After alkali dissociation into alkaline solution, alkaline anion and dye have nucleophilic reaction dyeing, so the reactive dyes Digital Printing Foundation slurry needs to add alkali to help dye dyeing fiber. In many alkaline reagents, we select nahco® as the alkaline reagent for the active digital printing base material. Why Choose Nahco? We are based on the following reasons: The dyes in the reactive dyes digital printing inks are usually single fluorinated or single chlorinated. These structures of dyes and baking soda have a good color fixing effect; In the reactive dyes digital printing base, Nahco? has a stronger ph cushioning capacity. The hydrolysis of sodium bicarbonate during steam solidification will form a cushioning system to ensure the stability of the ph on the fabric surface during steam fixation. The alkalinity is too strong, the covalent bond formed by dyes and fibers will quickly accelerate the bond fracture speed, and the fixing rate will be reduced. When the alkali is too strong, the stability of reactive dyes digital printing substrate is poor, the alkalinity is too strong, easy to dye before steam. Fiber reactions affect the reproducibility of printing; some fibers (such as protein fibers and viscose fibers) are hydrolyzed and destroyed under alkaline conditions, even ifDigital bottom PulpFiber damage and yellowing can also be caused in cellulose fibers at alkaline high temperatures. Yellowing and oxidation damage can also occur during baking. Through the above analysis, we all know that reactive dyes digital printing base should choose Nahco as ph regulator. Those who have done traditional printing know that if they want to print, they have to adjust the color pulp first. If you want to print which effect, you need to adjust the performance of the color block. Compared with the traditional active dye printing, reactive dyes digital printing ink plus reactive dyes digital Printing primer is equivalent to our traditional active dye slurry. At present, reactive dyes digital printing ink can not be directly added to the printing auxiliaries. Therefore, reactive dyes must be pretreated with reactive dyes digital printing primer before digital printing. Reactive dyes Digital Printing primer can adjust the digital printing effect, such as color yield, degree, uniformity, permeability and other functions, so as to show the importance of reactive dyes digital Printing primer in active digital printing. In order to analyze the basic slurry of reactive dyes digital printing in more detail, in the actual research, we usually divide the reactive dyes digital Printing Foundation slurry into two parts: Thickener and auxiliary agent.
