Micro-coagulation bead type efficient vapor permeability cloth printing and dyeing method

Abstract

The invention discloses a micro-coagulation bead type efficient vapor permeability cloth printing and dyeing method, and belongs to the field of printing and dyeing. A secondary coloring step is carried out through micro-coagulation beads, and dye is enabled to form steam and carry dye molecules to ascend into primarily colored cloth. Meanwhile, under the high-temperature effect of dye steam, themicro-coagulation beads are melted gradually, on one hand, internal double-state color liquid overflows and is in a gas state at a high temperature and infiltrates into the primarily colored cloth, and on the other hand, the melted micro-coagulation beads form a micro-isolation glue layer above the primarily colored cloth, so that the upward evaporation of the double-state color liquid is effectively prevented, and most of gaseous molecules of the double-state color liquid effectively permeate into the primarily colored cloth at a high temperature. Compared with soaking coloring in the prior art, dye and the double-state color liquid are converted into a gas state from a liquid state through secondary coloring, and coloring is performed in a gas state way, so that the gas state diffusion efficiency is higher compared with the diffusion efficiency of liquid, and then the coloring efficiency of the printing and dyeing method is remarkably improved.

Description

technical field [0001] The invention relates to the field of printing and dyeing, and more specifically relates to a method for printing and dyeing micro-bead type high-efficiency vapor-permeable cloth. Background technique [0002] Also called dyeing and finishing. It is a processing method, and it is also a general term for pretreatment, dyeing, printing, finishing, washing, etc.; the undergraduate dyeing and finishing major has now been incorporated into the light chemical engineering major; as early as the Neolithic Age six or seven thousand years ago, Our ancestors were able to dye sackcloth red with hematite powder. The primitive tribes living in the Nomuhong area of ​​the Qaidam Basin in Qinghai can dye wool into yellow, red, brown, blue and other colors, and weave woolen cloth with colored stripes. During the Shang and Zhou dynasties, dyeing technology continued to improve. In the palace handicraft workshop, there are full-time officials "dye people" to "hand dye ...

AI Technical Summary

Problems solved by technology

[0006] In the prior art, in the printing and dyeing process, the cloth to be dyed is immersed in the liquid dye, and the process of coloring the cloth is realized through the diffusion of the liquid in the cloth. However, the dye spontaneously diffuses into the cloth It is a relatively slow process, which leads to poor overall efficiency of printing, dyeing and coloring, and cannot adapt to the rhythm of modern large-scale production
