Abstract

The invention discloses a leather making method for magnetically processing leather making water and a leather chemical water solution into nanometer small-molecule water to be combined with an ultrasonic wave enhancement technology. The leather making method is characterized in that the magnetized nanometer small-molecule water is combined with the ultrasonic wave enhancement technology to be applied to each leather making procedure, so that the efficiency of the physiochemical process of each leather making procedure can be improved, the consumption of chemical materials is reduced, environmental pollution caused by the emission of harmful drugs and industrial wastewater is reduced to the maximum extent, the use quantity of water is greatly saved, the waste of water is decreased in the leather making process, and the production cost is reduced, so that the leather making method is a reform of the traditional leather making method and provides a new effective path for the developmentof the leather industry.

Description

technical field [0001] The invention relates to a tanning method for magnetizing tanning water and a leather solution into nano-molecular water and ultrasonic enhancement, and belongs to the fields of nanotechnology and ultrasonic enhancement technology for treating macromolecular water into small molecular water. technical background [0002] At present, the tanning industry still uses traditional tanning methods, that is, softening (soaking), liming and dehairing, deliming, pickling, tanning, neutralization, fatliquoring, dyeing, etc. A variety of complex physical and chemical processes. In the above-mentioned process, water and skin chemical solution can only enter through the water channel of the raw material skin cell tissue. The diameter of these water channels is about 2 nanometers and hexagonal, and the natural water with a diameter of 2.6-6 nanometers is macromolecular water (13 Long-chain water molecular clusters composed of more than one water molecule) and this ...
