specific Embodiment

[0064] Processing 100kg of sheep shearling leather with a black background and a gray complexion includes the following steps:

[0065] 101) Select sheep shearling leather with complete skin type, complete, clean wool, no knots, and no damage or rot on the skin board;

[0066] 102), first add 2000kg of water and 0.6kg of formic acid with a mass concentration of 85% to the retanning groove to make a retanning solution, put the selected leather into the groove, and soak for 30min at 35°C; Add 28kg of HLS-A type chrome tanning agent produced by Brother Technology Co., Ltd. to the solution and continue soaking for 240 minutes; finally add 2.4kg of sodium formate and soak for 8 hours to complete the retanning process. The shrinkage temperature of the leather after retanning is ≥95°C;

[0067] 103), formic acid with a mass concentration of 85%, industrial alcohol with a mass concentration of 95%, and water are made into a solution according to the ratio of 1:1:4, and evenly brushed...

Abstract

The invention relates to the leatherworking field, and specifically relates to a printing and color developing method of fur. The method comprises the following steps of: a) material choosing: choosing a fur material according to requirements; b) pretreatment: subjecting the chosen fur material to retanning treatment; c): fine treatment: straightening the hairs on the retanned fur material, and trimming as well as flattening the hairs; d): pattern printing: coating a printing solution on the hairs according to a needed pattern design; and e) dyeing: dyeing the printed fur material. The printing and color developing method of fur in the invention reduces the realization of a bicolor effect of single hair from two-step dyeing in traditional making processes to just one-step dyeing, thus reducing making steps and lowering the complexity degree of the making method. Based on the dye adsorption ability of a printing and color developing agent, the method in the invention depends on the difference between the dye adsorption degrees of a part coated with the printing and color developing agent and a part not coated by the color developing agent to realize the bicolor effect of single hair. Transition between the two dyed colors is more natural, and the effect is better than that of traditional methods.

Description

technical field [0001] The invention relates to the field of leather making, in particular to a color development method for fur printing. Background technique [0002] Since the beginning of the 21st century, the ancient and traditional fur industry has been full of vitality. With the rapid economic growth and the improvement of people's living standards, the rapid growth of consumption of fur clothing and fur products has been stimulated. The position of fur clothing and fur products in the clothing industry is becoming more and more important. They are not only a representative of identity, but also a symbol of fashion, and have broad development prospects. Changes in people's aesthetics have also promoted the continuous improvement of fur processing technology. In the prior art, if you want to print two colors on one piece of fur, you usually need to dye the pattern and the background separately, and the production method is complicated. Contents of the invention [0...
