Embodiment 1

[0059] Processing Rex Rabbit Skin

[0060] The first step, weighing, batching: choose fresh salted rex rabbit skin.

[0061] The second step, pre-processing:

[0062] (1) Immersion

[0063] Soak for 4 hours in an aqueous solution containing 20 / L of salt and 0.5g / L of Ailite wetting agent HAC under the condition of a solid-to-liquid ratio of 1:20; The aqueous solution of agent HAC1.5g / L, bactericide 0.3g / L and sulfuric acid 0.3g / L was intermittently rotated under the condition of solid-liquid ratio of 1:20, overnight.

[0064] (2) Washing

[0065] Wash with an aqueous solution containing 0.5g / L of soda ash, 2g / L of Weiss degreasing agent JA-50 and 0.5g / L of Weiss TS-80 at a temperature of 38°C and a ratio of solid to liquid of 1:20, and the washing time is 60 minute.

[0066] (3) Jieli, remove the meat

[0067] (4) Degreasing

[0068] Rotate for 60 minutes in an aqueous solution containing Eliite degreasing agent H 2g / L and soda ash 0.5g / L, and the temperature is 40°C, t...

Embodiment 2

[0083] The difference from Example 1 is that the compounding ratio of the fatliquoring agent added in the tanning (1) step is different, specifically as follows.

[0084] The first step, weighing, batching: choose fresh salted rex rabbit skin.

[0085] Second step, pretreatment: with embodiment 1.

[0086] The third step, tanning

[0087] (1) Use a solution containing 50g / L of table salt, 1g / L of Wheeler fatliquor FLH and 0.8g / L of Wheeler fatliquor FNP, and rotate for 30 minutes at 35°C and a solid-to-liquid ratio of 1:20;

[0088] (2) with embodiment 1;

[0089] (3) with embodiment 1;

[0090] (4) with embodiment 1;

[0091] The 4th step, post-tanning treatment is the same as embodiment 1.

Embodiment 3

[0093] The difference from Example 1 is that the concentration of the chrome-aluminum tanning agent AC added in the tanning (2) step is different, as follows.

[0094] The first step, weighing, batching: choose fresh salted rex rabbit skin.

[0095] Second step, pretreatment: with embodiment 1.

[0096] The third step, tanning

[0097] (1) with embodiment 1;

[0098] (2) After the first stage of tanning, add 0.5mL / L of formic acid and 8g / L of chrome-aluminum tanning agent AC, and rotate at 35°C for 20 minutes;

[0099] (3) with embodiment 1;

[0100] (4) with embodiment 1;

[0101] The 4th step, post-tanning treatment is the same as embodiment 1.

Abstract

The invention provides a tanning method for rex rabbit skin. The tanning method improves the tanning effect by combining different tanning means in multiple stages, remarkably improves the tensile strength and tear strength of the leather panel, and at the same time improves the tanning effect. Abrasion and rubbing resistance of Rex Rabbit leather. The tanning process is as follows: first-stage tanning is carried out by using a solution containing table salt 40-60 g / L, Willer fatliquoring agent FLH 1-3 g / L and Willer fatliquoring agent FNP 0.3-0.8 g / L; Add formic acid 0.3~0.8mL / L and chrome aluminum tanning agent AC3~8g / L to carry out second-stage tanning; then add chrome powder 3~8g / L and Weiss chrome retanning agent F-HN 3~8g / L to it L, carry out the third-stage tanning; then add 3-8 g / L of chromium powder and 0.7-1.3 g / L of sodium formate to it, overnight; then add 1.5-4.5 g / L of Weiss co-tanning agent F-B to complete.

Description

technical field [0001] The invention relates to the field of fur processing, in particular to a method for tanning rex rabbit skin. Background technique [0002] With the stable and rapid development of the world economy, people's living standards continue to improve. In the past, fur clothing, which was a symbol of wealthy businessmen and nobles, has gradually entered the lives of more and more fashionable consumers. At present, fur products are becoming more and more fashionable. , and its popular colors are increasing. At the same time, the fashion design of fur clothing styles and the extensive use of fur trims on other clothing have also increased the consumption of fur year by year. And with the trend of younger and younger consumers of fur clothing, personalization has become a new requirement for designs and colors. The increasingly mature and developing clothing industry leads the trend of fashion life and provides unlimited business opportunities for the fur proc...
