Embodiment

[0021] This embodiment involves a clean production and tanning process of rex rabbit fur, which includes the following steps in sequence: (1) immersion in water, (2) flesh removal, (3) degreasing, (4) pickling to soften, (5) heavy pickling, ( 6) Tanning, (7) Peeling and water control, followed by neutralization and fatliquoring and subsequent dry finishing operations.

[0022] In the water immersion step, the fur of the rex rabbit is placed in the normal temperature solution for 6-12 hours, and the solution in this step contains 0.5-1.5ml / L penetrant. The penetrant used is the penetrant JFC produced by Zibo Haijie Chemical Industry. The penetrating agent can increase the penetration of the degreasing agent on the fur, and the degreasing is more thorough.

[0023] In the de-fleshing step, use a circular knife machine and a wire machine to de-flesh the fur until there is no meat residue in the fur, the skin shape is complete, and there is no process damage. It lays the foundat...

Abstract

The invention discloses a rex rabbit fur cleaning production tanning process, and relates to rex rabbit fur cleaning production tanning processes. The process sequentially comprises the following steps of (1) carrying out soaking, (2) removing meat, (3) carrying out degreasing, (4) carrying out pickling and softening, (5) carrying out re-pickling, (6) carrying out tanning, (7) carrying out fur discharging and water controlling, and then carrying out neutralization and fat adding as well as subsequent drying finishing operation. In the degreasing step, a degreasing solution is used as a solution for soaking treatment; and treatment solutions of the soaking and softening step, the re-pickling step and the tanning step can be repeatedly reused. Compared with traditional fur chrome tanning andaldehyde tanning technologies, a formaldehyde-free chrome-free tanning technology is adopted, the method that the treatment solutions are repeatedly used is adopted, therefore, the fur tanning process can save chemical raw materials by 60% or more, and the water consumption can be reduced; the emission of harmful substances can be reduced, and no formaldehyde and chromium elements are contained in the sewage; and moreover, a fur white board of a fur treated by adopting the process is white, and better conditions are provided for dyeing.

Description

technical field [0001] The invention relates to a fur tanning process, in particular to a clean production tanning process for rex rabbit fur. Background technique [0002] Rex rabbit fur collar coats and rex rabbit shawls are mainly made of fur from rex rabbits. The traditional rex rabbit fur tanning method specifically includes: soaking in water, fleshing, degreasing, washing, enzymatic softening, pickling, tanning and other processes. In the whole tanning method, there is a large amount of chemical raw materials. Moreover, most furs are tanned with chrome, and the tanned furs have excellent properties, and are still the mainstream method of fur tanning. Chrome tanning and chrome retanning are processes that will produce chromium pollution in the fur processing process. In the actual production process, the utilization rate of chromium is about 30%, and the remaining 70% of the chrome tanning agent enters the wastewater. The main factor of fur industry pollution in chrom...
