Physical And Chemical Properties Of Soybean Protein Composite Fiber
The single fiber breaking strength of soybean protein composite fiber is higher than that of wool, cotton, and silk, second only to high-strength fibers such as polyester. The fiber denier is small and the DPf reaches 0.9dtex. The fabric feels soft and has good drape. Because of the high initial modulus of soybean protein fiber and low boiling water shrinkage, the fabric has good dimensional stability, moisture absorption and air permeability, excellent comfort, antibacterial and antibacterial, anti-ultraviolet, far-infrared and negative oxygen ion emission. This kind of health care function is a kind of good textile fiber.
A super-natural fiber developed on the basis of synthetic fiber-the main raw material of soybean protein fiber comes from natural soybean meal, which is rich in raw materials and renewable, and will not cause predatory development of resources. In the production process of soybean protein fiber, the auxiliary materials and additives used are non-toxic, and most of the additives and semi-finished fibers can be recycled and reused. The residue left after the protein is extracted can also be used as feed, and the production process will not pollute the environment. Soy protein fiber is made of squeezed soybean meal as raw material. Using engineering technology, the globulin in soybean meal is extracted to make a certain concentration of protein spinning solution, and then by adding functional additives, the protein spatial structure is changed. It is made by wet spinning. to make. Soy protein fiber is usually first defatted into soybean meal and pulverized into defatted soybean meal powder, then the soybean protein is separated by alkali extraction and acid precipitation, and then the separated protein is dissolved and spun.
