Embodiment Construction

[0024] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0025] A kind of preparation method of silk protein fiber provided by the invention, it comprises the steps:

[0026] (1) After stripping the silkworm cocoon shells into pieces, degumming 3 times with 3% sodium carbonate solution, each time boiling in a water bath for 30min, the bath ratio was kept at 1:50; after degumming, fully cleaned with distilled water, put Dry in a vacuum oven at a temperature of 75°C, then dissolve the dried silk protein in a NaOH solution with a mass fraction of 1.5%, and prepare a silk protein solution with a protein content of 13%;

[0027] (2) The wood raw material of the tree is processed by peeling-knotting-slicing, and then cooking-before bleaching and selection-bleaching-post-bleaching and selection-pulp making-d...

Abstract

The invention discloses a preparation method of silk protein fibers. The preparation method comprises the following steps of: (1) after peeling off cocoon shells into fragments, degumming a sodium carbonate solution with the mass percent of 3% for three times, and putting the fragments into a vacuum drying box at the temperature of 75 DEG C and drying; then dissolving dried silk protein into a 1.5wt% NaOH solution; (2) carrying out slicing treatment on tree raw materials, and boiling, finely selecting before bleaching, bleaching, finely selecting after bleaching, pulping, dehydrating and drying to prepare pulp; (3) filling the pulp and liquid-state NMMO (Methylmorpholine-N-Oxide) into a mixing kneading tank and heating the mixture at vacuum to 90 DEG C, so as to prepare a spinning solution with the cellulose concentration of 10%-25%; and (4) proportioning and commixing a silk protein solution in the step (1) and the spinning solution in the step (3), and adding a nano aromatic auxiliary agent and spinning by adopting a dry-wet-method process. The silk protein fibers provided by the invention have soft luster and a smooth and soft hand feeling of real silk, and also keep good moisture absorption and high fiber strength of natural silk; and the silk protein fibers are more skin-friendly and comfortable.

Description

technical field [0001] The invention relates to a method for preparing fibers, in particular to a method for preparing silk protein fibers. Background technique [0002] Silk is one of the earliest natural proteins used by human beings, and enjoys the reputation of "Fiber Queen". At present, China is the country with the largest silkworm silk and tussah silk production in the world, and the raw silk production of silkworm accounts for about half of the world. Most of the silk has been used as textile materials. The development and utilization of silk has gradually extended to the fields of food, new materials for fermentation industry, biopharmaceuticals, clinical diagnosis and treatment, environmental protection, energy utilization, medical materials and cosmetics. Silk protein has good biodegradability and biocompatibility, and is an excellent natural biological material. With the continuous improvement and maturity of processing technology, silk protein will have a broa...
