Embodiment 1

[0016] An auxiliary agent for rewetting of blue skin, its composition is: 52% adipic acid, 13% Pingpinga O-15%, 15% sodium dodecylbenzenesulfonate, 20% sodium tripolyphosphate, ground and pulverized Mix thoroughly afterwards. Carry out the rehumidification process on the long-standing dry and hard blue skin according to the following process, and conduct experiments and comparisons with commonly used rehumidification aids such as Pingpingjia, penetrating agent JFC, and degreasing agent.

[0017] The amount of material added is based on the quality of the pigskin shaved wet blue leather

[0018] Rinsing or rewetting distillation 200% temperature 32~38℃

[0019] Formic acid (85%) 0.3%

[0020] Rehumidification aid 0.7% 40~60min

[0021] Rinse and check for water return

[0022] The moisture rehydration aid mentioned in the process refers to Pingpingjia, penetrating agent JFC, degreasing agent and the aid of the present invention respectively using the same process for compar...

Embodiment 2

[0024] An auxiliary agent for rewetting of blue leather, its composition is: mixed acid 55%, Pingpingjia O-20 15%, sodium dodecylbenzene sulfonate 15%, sodium tripolyphosphate 15%, fully ground after grinding mix. Experimental comparison was carried out by the process described in Example 1.

Abstract

The invention provides a novel assistant for blue leather rewetting, the novel assistant for preventing leather face bursting and an application method of the novel assistant. The assistant includes an organic acid compound, a fatty alcohol-polyoxyethylene ether surface active agent, an alkylbenzene sulfonate surface active agent and calcium and magnesium ion chelate. The assistant is used for theblue leather rewetting procedure in the leather industry, blue leather softening and fold eliminating can be effectively achieved, a combined genuine leather face and calcium and magnesium salt of bath foam can be chelated, the leather hand feeling is soft and smooth, and leather face blasting is prevented in an assisting manner. The function for rewetting and fold eliminating for blue wet leather deformation due to long-time placement is particularly obvious.

Description

technical field [0001] The invention relates to the field of auxiliary agents for tanning production, more specifically, the invention relates to an auxiliary agent for rewetting blue leather and the usage of the auxiliary agent. Background technique [0002] As a traditional and modern industry, the leather industry is closely related to people's production and life. In order to meet the requirements of the market, tanners have been working hard to improve the quality of leather products. In the process of tanning, the quality of leather is not only related to the quality of raw leather, the quality of leather chemicals used, and the superiority of the process, but also has a lot to do with the mastery and control of each process in the process. [0003] As an important process in the dyeing and finishing part, the rewetting of wet blue leather has an important impact on the quality of the final leather product. Whether the wet blue leather is rewet is sufficient, to a ce...
