Embodiment 1

[0056] A preparation method for rex rabbit fur, comprising:

[0057] S1, softening and pickling the pretreated rex rabbit skin, specifically including:

[0058] The water temperature is controlled at 30°C, and the rex rabbit skin is softened for 48 hours in a softening solution with a salt concentration of 70g / L, a formic acid concentration of 2cc / L, a weak acid protease concentration of 1000 activity units, and a pH value of 3.0 to 3.3. Add 2cc / L of formic acid to the softened solution after softening, add sulfuric acid to adjust the pH value to 2.7-2.8, and complete pickling.

[0059] S2. Pre-tanning the Rex Rabbit skin, the pre-tanning includes the first pre-tanning and the second pre-tanning, specifically including:

[0060] Control the water temperature at 38°C, and tan the Rex Rabbit skin in the first pre-tanning liquor with a salt concentration of 50g / L, a BASF 1# syntan concentration of 15g / L, and a pH value of 3.8-3.0 for 8 hours. Sulfuric acid is added to the first...

Embodiment 2

[0068] A method for preparing rex rabbit fur, which is different from Example 1 in that: in step S1, the rex rabbit fur is not softened, but is directly pickled. The operations of the remaining S2, S3, S4, and S5 are the same as those in Embodiment 1.

Embodiment 3

[0070] One difference between it and Example 1 is that in the step S2, the pre-tanning of the rex rabbit skin is only carried out for the first time, and the second time is not carried out. The operations of the remaining S1, S3, S4, and S5 are the same as those in Embodiment 1.

Abstract

The invention provides a preparation method of rex rabbit fur, the rex rabbit fur and a fur product and belongs to the field of fine processing of fur. The preparation method comprises the following steps: pre-tanning rex rabbit fur, which is treated before tanning, by utilizing a synthetic tanning agent; carrying out oil tanning on the pre-tanned rex rabbit fur by utilizing an oil tanning agent.The rex rabbit fur is prepared through the preparation method. The fur product comprises the rex rabbit fur. In a preparation process, the pre-tanning of the synthetic tanning agent and the oil tanning of the oil tanning agent are combined; advantages of two tanning methods are complementary to generate positive synergistic benefits, so that the problem that formaldehyde and chromium exceed the standard is solved; the content of harmful components is low and the fur is soft and has rich elasticity and high tensile strength.

Description

technical field [0001] The invention relates to the field of fur finishing, and in particular to a preparation method of rex rabbit fur, rex rabbit fur and fur products. Background technique [0002] The fur and leather industry is a traditional industry with comprehensive advantages in my country, an important livelihood industry and an industry with certain international competitiveness.
