Abstract

The invention relates to feather protein viscose filament yarn and a manufacturing method thereof. The invention belongs to the material field of textile industry. According to the invention, feather protein liquid and a cellulose sulfonate solution with a weight ratio of 1-40%:60-99% are adopted; the materials are subjected to static blending, spinning, solidifying, and post-processing, such that the feather protein viscose filament yarn is obtained. During the production process, a protein loss of the feather protein viscose filament yarn is lower than 30%. After 50 times of washing upon a finished product, a fiber protein loss rate is no higher than 5%. According to the invention, the feather protein viscose filament yarn is manufactured by using waste feathers. The fiber performance is good, the cost is low, and the raw material sources are wide. The filament yarn and the manufacturing method are beneficial for environment protection.

Description

technical field [0001] The invention relates to a composite viscose filament and a manufacturing method thereof, in particular to a feather protein viscose filament and a manufacturing method thereof, belonging to the material field of the textile industry. Background technique [0002] Silk products are light and soft, with elegant luster, good hygroscopicity, and comfortable to wear. They are very popular among domestic consumers. However, due to the shortage of silk, the raw material for producing silk products, they cannot meet the needs of people's lives, and people turn to seek an alternative. The raw material of silk. Foreign countries have developed regenerated protein fibers, using casein, soybean protein, peanut protein and corn protein as raw materials, all of which were eliminated by other fibers due to low humidity, and then developed fibers such as vinylon, which have high strength. But the wearing comfort is poor. People try to blend and spin casein with pol...
