PRODUCTION DETAILS

Nowadays, many people are saying that they are producing eco-friendly slippers, but not many meet the requirements.

Environmentally-friendly slippers shoes should meet at least three requirements: (1) Shoes are environmentally friendly materials, that is, the materials are non-toxic and harmless, or taken from recycled materials, or the shoes themselves can be recycled or naturally degraded, etc. It will cause pollution to the environment; (2) This is a often overlooked part, that is, it will not cause environmental pollution and health damage to the operators during the production of shoes; (3) Shoes wear to the wearer There is no harm to human health.

In the production of leather, the tanning process is very important, and the chrome-free tanning method is a tanning method for treating leather with organic phosphorus salt.

Process: Unstable carcinogens Small molecules, if combined with human cells, or destroy the body’s cellular structure, are very harmful to the human body. Small molecules of carcinogens contact cell surface cells to induce cell proliferation or differentiation, produce cytotoxins, some infiltrate blood vessels, some stay on the surface of the skin, slowly combine and replicate, and eventually produce cancer.

Background: The traditional methods of tanning are the chrome tanning method and the aldoxime method. The chrome tanning method must use chromium powder in the operation, but trivalent chromium produces harmful substances, especially hexavalent chromium is a carcinogen. Hexavalent chromium is not only toxic, but also easily absorbed by the body and accumulates in the body. Hexavalent chromium compounds have obvious local stimulating effects and corrosive effects at high concentrations, and are common carcinogens at low concentrations. The “aldoxime method” will produce certain formaldehyde in the tanning system, which is more harmful to the human body and is a harmful carcinogen. Since the beginning of the 21st century, human beings have strengthened their awareness of environmental protection, and tanneries must produce environmentally friendly products at high cost to cope with the sales market. In combination with national requirements and consumer requirements, after years of professional research, the “Chromium-free bismuth method” (including titanium, magnesium, aluminum) has been developed, which is a tanning method for treating leather with organic phosphorus salts. The “Chrome Free Method” not only eliminates the use of chrome powder, but also avoids the production of formaldehyde in the process. After the safety test of international standards, there is no chromium or formaldehyde at all, because it is an organic phosphorus salt, so it does not increase any other carcinogens.

advantage:

1, environmental health has overcome the problem that can not be challenged, the harmful substances hexavalent chromium! formaldehyde! Azo aromatic amine! The content of carcinogens is reduced to a minimum. Hexavalent chromium and formaldehyde are carcinogenic substances, which directly affect human health. Although the azo dye itself has no direct carcinogenic effect, the aromatic amine reduced by azo dye has potential carcinogenicity. After the authoritative testing of IQTC and STR (the two major authorities of import and export inspection), hexavalent chromium and azo aromatic amines were not detected, and the formaldehyde content reached the secondary standard, which could be in direct contact with the skin.

2, fashion and beauty “No chrome enamel” leather color white as jade, the color is more vivid and bright, the traditional tanned leather can not reach the color.

3, practical wearable

Disadvantages:

1. The process is complicated and difficult to operate in the production process, and the cost is high.
