What is eco-synthetic leather?

Environmentally friendly synthetic leather, also known as green synthetic leather, refers to functional emerging polymer fabrics that are made of raw materials that are harmless to the surrounding environment and processed through clean production processes. They are widely used in all aspects of people's daily life. Life. It is characterized by energy saving and reduced impact on the environment, and can endow products with new ecological and green environmental protection functions, including water-based polyurethane synthetic leather, solvent-free synthetic leather, and microfiber synthetic leather. 


Therefore, the ecologicalization of the synthetic leather industry is also the development direction of the industry. The mainstream is to apply environmentally friendly green materials, promote clean process production, achieve efficient production, reduce consumption and reduce emissions, and follow the production method of circular economy development.

When the indicators of four chemical substances that are easy to exist in leather and are closely related to ecology are lower than the limit requirements, this kind of leather can be accepted by EU countries, also known as the real "ecological leather". i.e. eco-friendly leather). The four chemical indicators are: 


1) Hexavalent chromium: chromium plays an important role in tanning leather. It makes leather soft and elastic, and is an indispensable tanning agent. 


2) Banned azo dyes: Azo is a synthetic dye widely used in leather and textiles. Azo's harmful way is through contact with the skin to produce aromatic amines. Aromatic amines are carcinogenic when absorbed into the skin, so the use of such synthetic dyes should be banned. There are more than 2,000 azo dyes produced, of which about 150 are listed as banned azo dyes. At present, there are more than 20 kinds of banned azo substances that can be detected and harmful to human body listed in international regulations, which are commonly found in dyes. 


3) Pentachlorophenol: Pentachlorophenol is an invisible and intangible substance, and it is also an ingredient that needs to be added in the tanning process. Generally play a role of antiseptic. If the preservative treatment is not thoroughly treated, it will remain in the leather products, causing harm to people's lives and bodies. 


4) Formaldehyde: Formaldehyde is widely used as a preservative and leather additive. If the removal is not thorough, free formaldehyde can cause many diseases. For example, when the concentration is 0.25ppm, it will irritate the eyes and affect the nasal mucosa. Long-term exposure to formaldehyde can easily lead to blindness and throat cancer.


Raeela microfiber leather has no irritating odor, is environmentally friendly, does not contain heavy metals, does not contain cadmium, phthalates, and meets EU REACH standards. For leather products that come into contact with our bodies, it is best to choose high-end materials. Usually high-end microfiber leather is harmless. Many artificial blood vessels in the human body are made of polyurethane, which is harmful to the human body and cannot be used. Some leathers that we touch regularly, such as Raeela microfiber leather, are safe for our skin.
