Embodiment 1
[0037] A fur dye, prepared by the following method:
[0038] (1) 400g acid black 234 and 280g direct black 170 are added in the mixing kettle;
[0039] (2) Heat until the temperature reaches 30°C, add polyacrylamide 100g, sodium cumene sulfonate 50g, sodium polyphosphate 20g, 2-naphthalenesulfonic acid formaldehyde polymer sodium salt 20g, fatty alcohol polyoxyethylene ether 80g, Icy silicone oil 50g;
[0040] (3) Stir at a rotating speed of 1200r / h for 8h to fully mix the dye and the mixing aid to obtain fur leather dye.
Embodiment 2
[0042] A fur dye, prepared by the following method:
[0043] (1) 500g acid orange 7 is added in the mixing kettle;
[0044] (2) Make the temperature reach 10°C, add polyacrylamide 100g, sodium cumene sulfonate 1000g, sodium polyphosphate 250g, 2-naphthalenesulfonic acid formaldehyde polymer sodium salt 250g, fatty alcohol polyoxyethylene ether 1000g, ice Sensitive silicone oil 150g;
[0045] (3) Stir at a rotational speed of 1500r / h for 2h to fully mix the dye and the mixing aid to obtain fur leather dye.
Embodiment 3
[0047] A fur dye, prepared by the following method:
[0048] (1) Add 600g acid brown 422 into the mixing kettle;
[0049] (2) Make the temperature reach 50°C, add 100g of polyacrylamide, 50g of sodium cumene sulfonate, 50g of sodium polyphosphate, 100g of fatty alcohol polyoxyethylene ether, and 100g of ice-sensing silicone oil;
[0050] (3) Stir at a rotational speed of 1400r / h for 2h to fully mix the dye and the mixing aid to obtain fur leather dye.

Abstract
The invention relates to the field of double-face leather dyeing, in particular to double-face leather dye and a preparation method thereof. The double-face leather dye is mainly prepared from, by weight, 10-90 parts of dye and 2-20 parts of polyacrylamide. The dye is acid dye containing a sulfonic acid group or direct dye containing a sulfonic acid group. According to the double-face leather dye, the dye and the polyacrylamide with the specific matching ratio are selected, and the polyacrylamide is combined with the sulfonic acid group in the dye, so that the water soluble group amount in the dye is reduced, the combination firmness of the dye is increased, and the purpose of color increasing and fixing is achieved. Experiments find that compared with common double-face leather, reaching the same color and luster as the double-face leather, with no copolymer, the using amount of the double-face leather dye can be reduced by at least 15%, the cost is saved, and environmental pollution is reduced. The preparation method of the double-face leather dye is simple and easy to implement, and can achieve industrial production easily.
Description
technical field [0001] The invention relates to the field of fur leather dyeing, in particular to a fur leather dye and a preparation method thereof. Background technique [0002] In recent years, with the wide use of fur products, such as clothing fur, carpet fur, and the demand for aniline fur that can maintain the characteristics of "natural fur" has increased greatly, consumers have put forward higher requirements for fur products. The updated requirements have promoted the continuous improvement of the wool leather dyeing process, and at the same time put forward higher requirements for the dyes used, and the coloring of wool leather has become a problem that people pay more and more attention to. The ideal requirements for fur leather are: ① can be dyed at room temperature; ② good permeability; ③ good consistency, that is, the same color can be obtained by dyeing different fur leather (such as chrome tanned leather, vegetable tanned leather, etc.); ④ good level dyeing ...
