Technical Field

The invention belongs to the field of animal fur treatment, and particularly relates to a rex rabbit fur dyeing process and application thereof, and particularly relates to a rex rabbit fur dyeing process with bright color and application thereof.

Background

At present, some manufacturing methods of the traditional process are mostly used in the market for processing fine and miscellaneous fur, so that the fur has certain limitation on appearance. The rex rabbit cotton-padded mattress on the market at present mostly takes primary color, single colour as the main, and the colour is monotonous.

CN105648792B discloses a dyeing method of rex rabbit skin with breeze effect, which comprises the following steps: (A) selecting high-quality beaver rabbit skin for tanning, and adopting a Weijia dye-proof agent WTS-II aqueous solution with the mass percentage concentration of below 30% for dye-proof treatment; (B) dyeing the beaver rabbit skin subjected to dyeing prevention treatment by adopting an acid dye, drying, turning bran to fix color and finishing the hair quilt. The dyeing method for the beaver rabbit fur with the breeze effect, provided by the invention, is simple in process and convenient in operation steps, the front step and the rear step are connected tightly, the dyed beaver rabbit fur quilt has a stereoscopic impression, the quality is high, the bottom wool is darker, the color of the hair tip is lighter, but the whole fur quilt has a chromaticity which is transitional and natural, and a relatively natural dyeing effect with the breeze effect is presented.

CN105970693A discloses a dyeing process for foxes, raccoon dogs and mink skins for making fur, which comprises the following steps: firstly, weighing; secondly, softening the fabric; thirdly, retanning; fourthly, rinsing; fifthly, dyeing; sixthly, spin-drying; seventhly, drying; eighthly, polishing, namely putting the skins into a closed wood rotary drum, adding sawdust, brightener and fluffing agent, rotating for 1-2 hours, discharging the skins, and rotating a silk cage; and step nine, finishing and warehousing finished products. The dyeing process of the fox, racoon dog and mink skins for manufacturing the fur is energy-saving and environment-friendly, and reduces the manufacturing cost. But the problems of single dyeing and monotonous color exist.

At present, the demand of people on the design and color of fur is increasingly improved, and the single-tone fur cannot meet the demand of people. Therefore, how to provide a fur dyeing process with rich and bright colors becomes a problem to be solved urgently.

(2) soaking the dyed fur obtained in the step (1) in a sodium hydrosulfite solution of 0.32g/L for 8min, peeling, soaking in water for 10min, peeling, and drying to obtain a cleaned fur;

(3) spraying a mixed solution (v: v: v ═ 1:2:4) of a Weijia fur color removal agent S-R, formic acid and water on the fur quilt of the cleaned fur obtained in the step (2), drying at 85 ℃ for 9min, and carrying out bran turning to obtain the fur after color removal;

(4) soaking the bleached fur obtained in the step (3) in 0.32mL/L hydrogen peroxide solution for 18min, peeling, soaking in water for 10min, peeling, and drying to obtain washed fur;

(5) and (3) spraying the mixed solution of the Ailante tippy (10g/L), the Ailante tippy orange (10g/L), the Ailante tippy yellow (8g/L), the Ailante brush color agent B (12mL/L), the Ailante cosolvent C-10(12mL/L), formic acid (22mL/L) and alcohol (22mL/L) on the fur quilt of the washed fur obtained in the step (4), drying at 87 ℃ for 13min, and turning bran to obtain the fur sprayed with the fantasy color.
