Problems solved by technology

However, due to the fact that the surface of the leather is easy to produce or be stained with dirt during wearing and use, it is inevitable to use wet wipes or other leather cleaners containing water when cleaning. Discoloration, cracking, etc., especially for leather with poor wet rub resistance, after repeated wet rubbing and cleaning, the coating on the surface of the coating will fall off in mild cases, and the leather will crack and change color in severe cases

Abstract

The invention discloses an environment-friendly leather bag with high smoothness and a manufacturing method of the environment-friendly leather bag. The environment-friendly leather bag comprises softened leather, emulsion added oil, a tanning agent and a complexing agent and further comprises dye and water. The environment-friendly leather bag comprises, by mass percent, 100 parts of the softenedleather, 1-2 parts of the emulsion added oil, 10-20 parts of the tanning agent, 1-5 parts of the complexing agent, 5-10 parts of the dye and 10,000-15,000 parts of the water. The three edges of two pieces of same leather dried in the fifth step are sewn, and a zipper is sewn on the other side. The method is simple, one or more of acrylic resin, a polyurethane resin tanning agent, an amino resin synthetic tanning agent and an aromatic synthetic tanning agent are adopted as the tanning agent instead of the tanning agent containing the chromium element, and the leather is more comfortable, morehealth, greener, more ecological and more environment-friendly.

Description

technical field [0001] The invention relates to the field of leather bag production, in particular to an environmentally friendly leather bag with high smoothness and a manufacturing method thereof. Background technique [0002] Leather bag refers to a handbag made of leather, which belongs to daily necessities. Leather bags are bags made of real or artificial leather. Leather bags are more expensive, mainly include: purses, briefcases, book bags, etc.; according to the gender of the user, they can be divided into male bags and female bags. Leather bags are generally small in size and mainly contain more expensive things. 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. In the process of human evo...
