Feilai Stone, also known as "man-made composite environmental protection washing stone", is a new type of washing stone developed by Yuezhang science and technology research team in three years through the extraction of a variety of materials. At present, the technology is leading in the world and has applied for patents in many countries. For the entire clothing washing water industry has brought a breakthrough change.

At present, the original natural volcanic rocks in the market, in the process of washing water, will cause a large number of energy consumption waste enterprise costs. However, the feilai stone has strong abrasion resistance and less consumption, which not only saves the cost of the enterprise, but also shortens the washing time, saves a lot of water, reduces the production and operation links, greatly saves the production cost for the enterprise, and the generated small amount of waste is easy to deal with and does not pollute the environment, thus basically eliminating the generation of sludge.

The value of Feilai Stone to enterprises is mainly reflected in: saving enterprise cost, reducing operation links, energy conservation and emission reduction, playing a role in protecting ecological environment and waste reuse; The value of the whole industry and the country is mainly reflected in: bring about a breakthrough change for the industry, so that the washing stone will no longer become a serious hazard to the health of garment production workers, serious pollution of the natural environment as a price. It has achieved a qualitative leap and contributed to the protection of China's green mountains and rivers.
