Abstract

The invention provides a method for preparing a nano-feather down protein fiber membrane. Compared with the prior art, the present invention adopts a composite lye system and stirs at a low temperature of 20-25°C to dissolve the down. Moreover, the dissolution rate of feather down is higher than 98%, which has the advantages of high dissolution rate, energy saving and consumption reduction. The feather down prepared by dissolving has nano-fibril morphology, and can be prepared into nano-feather by natural drying or freezing method. Plush protein fiber membrane with high hydrophilic performance.

Description

technical field [0001] The invention belongs to the field of material preparation, and in particular relates to a method for preparing a nano-feather down protein fiber film. Background technique [0002] Proteins are important biopolymers that are widely used in the development of new and functional materials. Among them, the main body of feather down fiber is natural protein. If feather down protein is utilized, it can broaden the source of protein resources, which is of great significance. [0003] In the prior art, the dissolution rate cannot meet the requirement, and the prepared product does not have the morphology of nano-fibrils, which cannot meet the requirement. Contents of the invention [0004] The object of the present invention is to provide a kind of preparation method of nano-feather down protein fiber membrane, adopt composite lye system, can dissolve and prepare feather down under low temperature condition, and, dissolving rate is high, can nano-fibril a...
