Efficient energy-saving reactive printing process

Abstract

The invention discloses an efficient energy-saving reactive printing process, which comprises the following steps: (1) pretreatment: performing body inspection, cloth arrangement, sewing, singeing, desizing, scouring, oxygen bleaching and mercerization on to-be-reactively printed cloth in sequence; (2) size mixing: melting colorants used for reactive printing under the condition of 70 to 90 DEG C, filtering and then adding the molten colorants to raw paste, and evenly stirring; (3) printing: during printing, arranging a printing screen of a dark colorant to be in front of a printing screen of a light colorant; (4) after the printing is finished, ageing, washing and setting to obtain a reactive printed product. According to the efficient energy-saving reactive printing process disclosed by the invention, through a chemical action between the dye colorants and the cloth, the color fading problem of reactive printing can be thoroughly solved, so that the product quality is greatly improved; meanwhile, compared with traditional reactive printing process, the efficient energy-saving reactive printing process has the advantages that processes are saved, the printing cost is reduced, and the production efficiency is increased.

Problems solved by technology

[0002] In the production of reactive printing, often due to the large color contrast of each printing color, the number of sets is large, and the cloth surface is singeing endlessly, the garden screen runs slightly during the operation of the machine, which will cause dark colors to spread into light colors or light edges. There is dark silky dragging at the mouth, which affects product quality

Conventional methods to solve the problem of color dragging: through singeing twice, the hairiness on the cloth surface will be burnt more cleanly to reduce the color dragging, but this will increase the process, increase the cost, and reduce the production capacity; or improve the running accuracy of the machine To solve the problem of color dragging, however, this method is not easy to improve the accuracy of the pattern for different printing machines; and the adjustment of the viscosity of the slurry and the pressure of the scraping can only reduce the color dragging phenomenon, but due to various Due to the difference in human operation level, it is more difficult to adjust, and the effect is not very ideal

When encountering dark-colored and light-colored flowers; or dark-colored edging, light-colored flowers are often encountered in the printing of such patterns, and the problem of color dragging is often encountered. If the problem of color dragging is not solved, the quality and effect of the pattern will be affected. will have a greater impact

[0003] The above is only to improve physically (that is, mechanical control, operation, etc.), but it cannot solve the problem fundamentally.
