Problems solved by technology

At present, the common fatliquors mostly start from the feel of the fatliquored leather board, and seldom pay attention to the absorption effect of the fur to the fatliquor (the absorption rate is low). In order to achieve a good fatliquoring effect, it is necessary to Increasing the amount of fatliquoring agent will inevitably lead to waste of raw materials and environmental pollution

Abstract

The invention provides a double-face leather fatting agent and a preparation method thereof, and belongs to the technical field of double-face leather processing. The double-face leather fatting agent comprises the following components in parts by weight: 70-85 parts of neutral oil and 15-30 parts of emulsifier, wherein the neutral oil comprises chlorinated alkane, epoxidized oil ester, higher aliphatic acid and higher aliphatic alcohol; the emulsifier comprises an ampholytic surfactant, a nonionic hydrophilic surfactant and a nonionic lipophilic surfactant. After the fatting agent provided by the invention is applied to the main oiling process of double-face leather, the absorptivity of the fatting agent can be up to 93-96%, the leather board is flexible, full, strong in forming sense, shallow in color and smooth and moist in hand feel, good fatting effect is provided, and the defect that the common fatting agents in the prior art are low in adsorptivity to cause waste and environment pollution is overcome.

Description

technical field [0001] The invention relates to the technical field of wool leather processing, in particular to a wool leather fatliquoring agent and a preparation method thereof. Background technique [0002] The fatliquoring agent for fur leather requires that after oiling, the leather board is soft and has a sponge-like foaming feeling, the flesh surface of the leather board feels smooth, has a certain degree of moisture retention, the color of the leather board is light, and has good light resistance. [0003] During the fatliquoring process of fur leather, in order to reduce the pollution to the environment, the fatliquoring agent should be absorbed by the leather plate as much as possible, so that its residual amount in the fatliquoring bath is small. At present, the common fatliquors mostly start from the feel of the fatliquored leather board, and seldom pay attention to the absorption effect of the fur to the fatliquor (the absorption rate is low). In order to achie...
