Abstract

The invention discloses a multifunctional protein fiber and a preparation technology thereof. The preparation technology comprises adding natural additives with functions of antibiosis, mildew resistance, mosquito and insect prevention and cooling into main fiber raw materials such as soybean protein, polyvinyl alcohol (PVA) and carboxymethyl chitosan to obtain a spinning stock solution with a plurality of functions, preparing a fiber semi-finished product from the spinning stock solution through a wet spinning technology and carrying out finishing so that mechanical properties of the protein fiber are improved and the multifunctional protein fiber with excellent mechanical properties is obtained. The multifunctional protein fiber and the preparation technology solve the problem that the common protein fiber on the market has a single function, is produced by complex processes, has no lasting effects and has a high production cost. The multifunctional protein fiber has effects of softness, skin adaptability, moisture absorption, humidity elimination, antibiosis, mildew resistance, mosquito repellency, insect prevention and skin cooling and has a good market prospect.

Description

technical field [0001] The invention relates to the technical field of textile industry, in particular to a multifunctional protein fiber with soybean protein and polyvinyl alcohol as main raw materials and a preparation method thereof. Background technique [0002] With the increase of the world's population, people's demand for fiber is gradually increasing. It is estimated that by 2050, the total demand for fiber will reach 90-100 million tons. With the improvement of people's living standards and the development of science and technology, people have put forward higher requirements for clothing fabrics. At present, natural fibers are favored by consumers for their natural environmental protection, no damage to the skin, comfortable hand feeling, moisture absorption and breathability. [0003] The raw materials for the preparation of protein fibers are mostly derived from milk, peanuts, corn, soybeans, etc. Soybean is rich in protein, and the cost is low, so soybean pro...
