Pattern spraying/coloring process for fur

Abstract

The invention discloses a pattern spraying / coloring process for fur. The pattern spraying / coloring process comprises the following process steps: mixing water, formic acid, a dye leveler, water-soluble organic solvent and a dye to form a mixed liquid, and putting the mixed liquid into numerical control spraying / dyeing equipment; arranging and sizing to-be-processed fur through steam; flatly putting the sized fur into the numerical control spraying / dyeing equipment; starting the numerical control spraying / dyeing equipment, and carrying out spraying and painting operations by virtue of a spray head on the numerical control spraying / dyeing equipment according to the program set in advance until pattern painting is finished or coloring is finished; carrying out high-temperature fixation on the sprayed / colored fur for 1-15 minutes; and carrying out drying treatment, and then warehousing. The pattern spraying / coloring process is simple, low in cost and free of pollution; the pattern is convenient to modify; and the pattern painting and coloring effects are good.

Description

technical field [0001] The invention belongs to the technical field of printing and coloring, and in particular relates to a fur spray pattern / coloring process. Background technique [0002] At present, on fur (fur) coloring or printing patterns, the traditional craft method is to adopt the method of plate-making printing, and this method can dye and print some patterns on fur; But the shortcoming of this craft method is: 1 , complex process, cumbersome and high labor costs, most of the existing printing patterns on fur are manually printed, so the labor cost is high and the efficiency is relatively low; also because the patterns that need to be printed are dyed and printed in different It is on the printing plate, so it is very inconvenient to modify the pattern; 2. After printing, the colloids and dyes with fur residues need to be cleaned, and the dyes themselves and the colloids contain some harmful substances, which are easily polluted when discharged to the outside worl...

[0002] At present, on fur (fur) coloring or printing patterns, the traditional craft method is to adopt the method of plate-making printing, and this method can dye and print some patterns on fur; But the shortcoming of this craft method is: 1 , complex process, cumbersome and high labor costs, most of the existing printing patterns on fur are manually printed, so the labor cost is high and the efficiency is relatively low; also because the patterns that need to be printed are dyed and printed in different It is on the printing plate, so it is very inconvenient to modify the pattern; 2. After printing, the colloids and dyes with fur residues need to be cleaned, and the dyes themselves and the colloids contain some harmful substances, which are easily polluted when discharged to the outside world Environment; 3. It is difficult for plate-making printing to dye the deep fur, so that the pattern of the printed and dyed clothes is easy to blur after repeated washing; 4. When printing and dyeing, one pattern may need to use multiple templates, so the job positioning High requirements; 5. Due to the difficulty of positioning and the technical constraints of the existing plate printing technology and the color separation and balance, it is impossible to realize the processing and production of true color patterns, and the boundaries between the colors of this plate printing technology are easy to be superimposed. Confused colors, making its color separation positioning inaccurate; so it is necessary to improve
