01.What do we do?

What are negative oxygen ions?

Negative air ions are often referred to as “vitamins in the air.” They are charged particulates suspended in the atmosphere, much like vitamins in food. These ions enter the body through the mouth, nose, or skin, helping to restore the body’s natural state of balance. It is generally believed that the concentration of negative air ions in the air serves as an indicator of how fresh and clean the air is.

What health benefits do negative oxygen ions offer to the human body?

It emits a high concentration of negative oxygen ions, which help improve respiration, relieve fatigue, promote blood circulation, provide antioxidant and anti-aging benefits, eliminate static electricity, inhibit bacterial growth, exert antiviral effects, deodorize and remove unpleasant odors, and enhance thermal insulation. Long-term use can boost the body’s immune function and contribute to overall health.

How are negative oxygen ions generated?

It is the electrons released when atmospheric gases are ionized under the influence of ultraviolet radiation, cosmic rays, radioactive substances, thunderstorms, and other factors, which promptly combine with neutral molecules in the air to form negative ions. 
Under the impact of the falling water, molecular dissociation also generates a large number of negative ions. 
The tip discharge of plants in the forest and the photoelectric effect generated by photosynthesis in green plants also produce negative ions. 
Negative ions are also generated in certain crustal rocks. That’s why forests, waterfalls, and seashores—where negative-ion concentrations are high—feel especially soothing.

Manufacture of Negative-Ion Fibers

Drawing inspiration from nature, we are committed to authenticity, weaving the very essence of the world into a second skin.

Negative-ion fibers or textiles are produced by blending and spinning, incorporating trace amounts of radioactive rare-earth minerals or natural ores into the fabric matrix. These minerals are rich in naturally occurring elements such as neodymium and uranium, which continuously emit low-dose radiation, ionizing airborne particulates and thereby generating negative ions.

Global Networking: How Supply Chain Restructuring Is Reshaping the Textile Industry

For decades, the textile industry has operated under a relatively stable, linear model: raw materials are sourced in one region, processed and manufactured in another, and ultimately consumed in Western markets. That era is long gone. Today, driven by a confluence of factors—including geopolitical tensions, shifting cost dynamics, and the urgent imperative of sustainable development—the industry is undergoing one of the most profound supply-chain transformations in its history. The result is a more decentralized, more resilient, and strategically more complex global production landscape.
