The theoretical analysis of sodium alginate and A state paste made of emulsified paste for the coating and reactive dye paste printing process to achieve a reliable foundation for the paste. The use of non-ionic or anionic binders does not cause agglomeration with the anionic sodium alginate and reactive dyes. In the process of steaming, reactive dyes transfer to the surface of the fiber and react with it to fix its color. At the same time, the binder forms a film on the surface of the fiber, blocking the coating and the fixed reactive dye, reducing the floating color and improving the The color yield and color fastness can also be improved.  A factory used to print a dark green bulk pattern on a fine cotton cloth. The formula for the coating and reactive dye paste printing is:  Active Green Blue K-G 2 %, Reactive Yellow K 4G 0.5 %, Paint Green FGB 2 %, Adhesive 10 %, Anti-stained Salt S 1 %, Urea 3 %, Baking soda 1 . 5 %, 45 % semi-emulsified paste.  Process flow: semi-products → printing → steaming → washing → soaping → washing → after finishing  Paste production: raw alginate paste (6 % ) 20 % to 30 %, A state pulp 20 % to 30 %, reactive dye 2 , paint Y , urea 1 % to 10 %, binder 10 % to 20 %, anti-salt S 1 , 1 % to 3 % baking soda, and 100kg of water added. The original paste of sodium alginate and A state pulp were mixed into a half-emulsified paste, and reactive dyes, anti-staining salts s and urea were opened with hot water, and the paste was cooled and then filtered. The paint and adhesive are diluted with cold water and then filtered in a human color paste. Finally, the baking soda is opened with water, filtered into the color paste, and stirred for use.  With the above-mentioned reactive dyes and coatings with the same slurry printing and full reactive dye printing, the dry friction, wet friction, perspiration resistance and other fastness generally improved by half, the cost slightly decreased. The effect of the cloth surface is more uniform than that of the full-reactive dyes ( all active dyes are printed with slightly colored dots ) .  It is feasible to use the active coating with the paste printing. The advantages are: the amount of dyeing material can be reduced, the color paste can be easily produced, and knife lines, plugging nets, color dots and other defects can not be easily produced. Overcame the problems of color difference, light color, color flower, etc., which are easily appeared in printing full-surface dyes of large-reactive dyes, and solved the problem that it is difficult to control the green color light for a long time. However, there are still some defects in the process, such as poor stability of the color paste, should not be put for a long time, color paste should be used with the use, color paste production process must be strictly in accordance with the process operating procedures, color paste temperature should not be too high, so as not to cause condensation.  Zhejiang Bolong International Industry&Trade CO.,LTD , https://www.bolongjackets.com
