Soybean fiber is a new type of regenerated plant protein fiber made from degreased soybean meal as raw material, extracted and synthesized from plant globulin. It was independently developed by Chinese textile science and technology workers and is internationally recognized. It took the lead in realizing high-tech industrial production and is also the only fiber invention with complete intellectual property rights that my country has obtained so far.
Before becoming fiber, protein and polymer must be extracted from soybeans as raw materials, processed using high-tech techniques such as bioengineering, and wet-spun. This kind of monofilament has fine fineness, light specific gravity, high tensile strength, strong acid and alkali resistance, and good moisture absorption and moisture conductivity. It has a better feel than cashmere, a luster comparable to that of silk, and excellent properties such as cotton's warmth retention and good skin-friendly properties. It is known as the "healthy, comfortable and environmentally friendly fiber in the new century."
High-count yarn blended with more than 50% soybean fiber and long-staple cotton is used to produce thin fleece sweaters in spring, autumn and winter. It is smooth, waxy, light and soft, and can retain worsted fabrics. It has a high luster and fineness and a smooth and waxy feel. It is also an ideal fabric for producing light and soft high-end suits and coats.
Fabrics made of soybean fiber interwoven with silk or blended with spun silk can not only maintain the luster and elegance of silk, but also improve its drape, eliminating sweat stains and moisture absorption that stick to the skin. It is an ideal fabric for making high-end clothing such as pajamas, shirts, and evening dresses.
In addition, soybean fiber blended with flax and other hemp fibers is an ideal fabric for making functional underwear and summer clothing; high-count yarn blended with cotton is an ideal material for making high-end shirts and high-end bedding; Or add a small amount of spandex to make it soft and comfortable to the touch. It can be used to make T-shirts, underwear, beachwear, casual wear, sportswear, fashionable women's wear, etc., with a very casual style.
Soy protein fiber was successfully developed by Mr. Li Guanqi, chairman of Huakang Group, after ten years of research and development, and won the World Invention Patent Gold Award. Mr. Li Guanqi’s invention brought a new revolution to the textile industry. It created four firsts in the history of the development of fiber materials and the history of the invention of man-made fibers. First, for the first time, artificial plant protein fiber was successfully researched and industrialized. Prior to this, developed countries had begun research in this area since the last century. The United States, Japan and other countries in the middle of the last century Conducted research on soy protein fiber, and the United States also gave their soy fiber a trade name, but they all failed because they could not meet the technical indicators required for textiles; secondly, he was the first person in the history of the invention of man-made fibers in China. Soybean fiber is known as the eighth largest man-made fiber in the world. The first seven types of polyester, nylon, spandex, acrylic, viscose, polypropylene and vinylon are all foreign inventions. Li Guanqi is the first Chinese to break the record of zero in the history of man-made fiber invention; Third, as a non-professional inventor, he stood on the podium of the World Gold Award for the first time; fourth, as a farmer inventor, he stood on the podium of the national award for the first time.
In addition, soy protein fiber is also the main raw material for making vegetarian meat. To manufacture soybean protein fiber, first add low-temperature defatted soybeans to water or dilute alkali solution and stir to obtain a solution. Dilute acid is added to this solution to precipitate the soy protein. The precipitate is washed with water, dehydrated and dried, and then alkali is added to dissolve it and become a spinning solution. The spinning liquid is passed through a membrane with small holes and squeezed into an acetic acid solution containing salt, so that the protein coagulates and precipitates to form a filament, which is then further stretched to form a fiber.
