Problems solved by technology

[0006] There are two main ways to clean leather in the prior art, one is hand washing, which can effectively deal with local scratches and surface dirt, but this method can only remove surface stains, but cannot remove the residual dimethyl fumarate , and if the cloth used for cleaning is not properly selected, it will cause greater damage to the surface
Another method is machine washing, which is quick and easy, however brightly colored leathers should not be machine washed as they may fade, nor should leather items with delicate stitching or many small trimmings as they can easily be damaged by the washing machine , Improper choice of cleaning fluid will cause leather damage

Abstract

The invention provides a low-loss cleaning process for leather and belongs to the field of cleaning. The low-loss cleaning process for leather comprises the following steps: spraying a cleaning liquidto the surface of the leather; erasing the cleaning liquid by using anhydrous lint free cloth; naturally airing the leather; and spraying a leather nursing agent to the surface of the leather. The invention also provides the corresponding cleaning liquid and nursing agent for the process. The cleaning liquid is prepared from sophorose ester, an active polysaccharide-collagen complex, synthesizedhectorite and water. The nursing agent is prepared from an inorganic salt-guar gum complex, water soluble vegetable oil, a chelating agent and water. Residues of harmful substances of the cleaned leather cleaned by the process are reduced, and the leather has a certain mildewproof ability.

Description

technical field [0001] The invention belongs to the field of cleaning, in particular to a low-damage cleaning process for leather. Background technique [0002] Leather is denatured and non-perishable animal skin obtained through physical and chemical processing such as depilation and tanning. Leather is composed of natural protein fibers tightly woven in three-dimensional space. There is a special grain layer on the surface, which has natural grain and luster, and feels comfortable. [0003] Expensive leather can only be wiped and spot cleaned, but if it is a leather wallet that has been used for a long time, or other nubuck leather products, it can be washed in the washing machine. Make sure to use a suitable soap and cold water to avoid warping the leather. To be on the safe side, it is still best to hand wash the leather. Unfinished leather products need to be protected and maintained with extra care, especially mildew resistance. [0004] Dimethyl fumarate is a comm...
