Calico | Changyi official enriching | flat screen prints provided by the official dispersed enriching. Calico | Changyi after the official enriching | flat screen prints are dispersed after officials enriching Changyi City, Shandong Province Textile Co., Ltd. (www.fumintex.com) 2013 upgrade been newly launched production of reactive dye printing paste found in the amount of over- for a long time, easy to clean flat screen floating color dispersion calico, affect the fabric skin friction prison and scrub fastness. Therefore, attention should be used to control the amount of reactive dyes. 1. With baking soda paste printing method? Disperse / reactive dyes with baking soda paste printing is generally used as a reactive dye fixing alkali agent. First by baking so disperse into the polyester melt, and then steamed to make the cotton fiber reactive dyes. ? Soda consumption more dispersed calico, the higher the curing temperature, the more serious the fabric yellowing. ? When mashing, the first reactive dyes modulated into paste, but not with the full amount of liquid, disperse dyes with two times the amount of about 40 ℃ warm water into a paste, then add diluted with water before use filtered into active dyestuff the. ? Proportion of reactive dyes and disperse dyes used to fight, with the proportion of cotton blended and dye performance, are generally to be able to print the same hue as the principle of uniformity of color, proportion and domestic disperse dyes to 3:2-2: a good calico, can also be used in a 1:1 ratio. Fight with the appropriate proportions, the color uniform, plump export calico, mutual contamination less than the white, white. Dyeing process conditions (1) wetting agent or wetting agents can be excluded penetrant fabric air conducive fabric dye penetration into the interior fabric treatment before sufficient time to increase (2) swimming shift phenomenon and prevent a lack of affinity for dyes for polyester , prone to drying phenomenon reasonable ways to enhance drying padding effect, reducing the rate with liquid, cotton with liquid rate decreased by 20% to 30% after that, will not change significantly swimming shift adding an appropriate amount Antimigrant melt dyeing time After drying and timing fabric dyes remain in the fiber surface, there is no fixing of the fiber occurs, a high temperature diffusion inside the fiber by heat curing, a dye, the dye through the fiber, complete fixing - Solid Color high melt - Dye sublimation more time to fight color, dye sublimation resistance should be similar
