Description
Technical field
The present invention relates to peanut protein and chitin blending fiber preparation method, is raw material with peanut processing residue peanut dregs and aquatic products processing residue chitin specifically, produces the method for functional fiber.
Background technology
In recent years, along with the change of people life style and the raising of the level of consumption, great variety is taking place in textile raw material, light in order to adapt to dress, the characteristics of comfortable and nourishing healthy, textile raw material trend " light; gentle; pine; as to hang down ", comfortable attractive in appearance, nurse functions such as convenient and health care and become the target that people pursue, these factors promote, promoted the development of textile raw material: it is reported that useful milk protein makes fiber, useful soybean protein is made fiber, useful peanut protein is made fiber, but does not also have the report of peanut protein and chitin blending fiber.
China is peanut production and consumption big country, and the peanut dregs annual output is extracted peanut protein except small part and is used for medicine and the food service industry about 2,500,000 tons, and the overwhelming majority is used for animal feed, and resource utilization is low, is a kind of huge waste to resource.The peanut protein that utilization is extracted from peanut dregs is produced ground nut fiber, has not only solved wasting of resources problem, and provides a kind of good raw material for textile industry.Improved the added value of peanut.
Chitin fiber is the found unique a kind of positively charged animal fiber of present occurring in nature, have undersaturated cation group in its molecule, therefore all kinds of harmful substances, the harmful bacteria to negative electrical charge has powerful suction-operated, it just can suppress the activity of harmful bacteria like this, lose activity, thereby reach antibiotic purpose.And this fiber had not only had the structure of string but also had the human body ossein organizes similar structure, with human body good compatibility is arranged, can be decomposed by the lysozyme of human body and absorb, thereby the textiles that makes this material have good medical science characteristic to be made by it has good bacteriostasis, and deodorization effect, according to test, contain 2.5% chitin in the textiles, its antibacterial action can satisfy the human antimicrobial demand fully.At present the chitin fiber of producing is also thicker, and powerful also special low (wet especially strong, main cause be porous fibre), volume weight are bigger, and these have determined the spinnability and the spinning process of chitin fiber.Ground nut fiber and chitin fiber merge mutually, efficiently solve this problem.
Summary of the invention
The object of the present invention is to provide a kind of raw material wide material sources, cost is low, and hygroscopicity, gas permeability and good spinnability are easy to process and have the blended fiber of health care.
The present invention solves the problems of the technologies described above the technical scheme that is adopted to be:
(1) with the peanut protein dispersing and dissolving in the combination solution of NaOH and urea, at room temperature stirring obtains peanut protein solution;
(2) chitin is dissolved in the combination solution of NaOH and urea, stirring at low temperatures obtains chitin solution;
(3) with above-mentioned two kinds of solution in the abundant mixing of required ratio, obtain spinning slurry;
(4) spinning slurry is filtered through plate and frame filter press, behind the vacuum discontinuous degassing, under room temperature, in coagulating bath, pass through wet spinning process, with peanut protein cellulose mixed solution and sprayed silk, spinning slurry is pressed in the coagulating bath through spinning head, adopts wet spinning to produce peanut protein and chitin blending fiber in coagulating bath.
Peanut protein purity described in the step (1) is more than 90%; The concentration of NaOH is 8%～12% in the combination solution of described NaOH and urea, and the concentration of urea is 15～18%; Whipping temp is 18～35 ℃; According to the quality of the peanut protein powder that adds, the peanut protein solution concentration that obtains is 3%-10%.
Whipping temp described in the step (2) is-20 ℃～-10 ℃; The concentration of NaOH is 8%～12% in the combination solution of described NaOH and urea, and the concentration of urea is 15～18%; The chitin solution concentration that obtains is 1%～3%;
The mixing of peanut protein solution and chitin solution is mixing in 1: 3～5: 1 in proportion in the step (3);
Coagulating bath prescription described in the step (4) is concentrated sulfuric acid 10-30g/l, potassium sulfate 210-230g/l, the glyoxal of 5-10g/l; Described coagulation bath temperature remains on 40～50 ℃, and the traction multiple is 3～5 times.
Its performance is for doing fracture strength (CN/dtex) 1.5-2.3; Wet breaking strength (CN/dtex) 0.8-1.6; Dried elongation at break 13-25%; Wet elongation at break 18%-30%; Regain 6-15%.
Peanut protein chitin fiber of the present invention has good hygroscopicity, gas permeability, soft, gloss is soft, good spinnability, the clothes that utilizes the peanut protein chitin fiber to make has the activation aged cells, the antibiotic enzyme of activating human body, lysozyme enhances metabolism, cleaning skin and suppress vegetative effect.Its raw material sources are wide, and cost is low, can produce in enormous quantities, have favorable economic benefit and social benefit.
