Li Guanqi - Founder of LGQ
Origin of the Invention (1991)

From soybean meal to fiber,
from invention to brand.

The story of LGQ® began with Mr. Li Guanqi's long exploration of soy protein fiber. From around 1991 onward, he worked to transform the soybean meal left after oil extraction into a plant-protein fiber that could be spun, woven, and applied. Behind this invention lies a lasting commitment to resource reuse, environmental protection, and sustainable development.
