Description
Technical field
The invention belongs to the cellulose fibre technical field, more specifically relate to a kind of fibroin blending regeneration cellulose fiber and preparation technology thereof.
Background technology
The market scale of whole world fibroin industry is at 50～6,000,000,000 dollars, and silk fibroin powder accounts for 50% share, and its range of application is more extensive, and is running stores, will reach more than 10,000,000,000 in 3 years its market scales.
Aspect processing, take Japan as main, its Application Areas spreads all over medicines and health protection, food and beauty industry to fibroin at present, and major product has cosmetics, health food, and technical merit is also led over other country.So that its added value of product is high.China through the number development of decades, has now become the fibroin place of production very important on the silk market, the world since new China sets up, the main place of production is Zhejiang and Jiangsu two provinces.But the high-quality fibroin of China is few, and added value is low.
The market overall situation is badly in need of the appearance of fine silk fibroin powder.100 nanometers are 1/75th of human body face pores, very easily absorb.Fibroin contains 19 seed amino acids because of it; nearly 20 kinds of mineral matters; the high-activity biological taurine; abundant fibroin and a large amount of trace elements; can improve the activity of flight against senium of human body factor S OD and amino acid carrier GSH-PX, the effect with the arresting convulsion of calming the nerves, clearing heat and detoxicating, thin protecting liver, coordinating intestines and stomach, additional calcium system, microelement-supplementing for oral administration.External application energy delaying skin aging, nti-freckle, anti-acne, crease-resistant strengthen the multiple efficacies such as skin gloss and elasticity.The appearance of nano-grade silk albumen powder is so that the practical application of silk fibroin powder aspect beauty and health care obtained the raising of the order of magnitude.
There are now two kinds of silk fibroin powders, micron order silk fibroin powder and nano-grade silk albumen powder on the domestic and international market.
Traditional preparation technology can make the silk fibroin powder of 3-10um, and particle diameter is large, and absorptivity is low, and its process energy consumption is large, and production cost is high, and nutrition in the fibroin is damaged or dissolves.After testing, the silk fibroin powder after traditional chemical method preparation technology makes, amino acid be surplus 3-6 kind only, and because product particle is many more than 5um, absorptivity is low simultaneously.
The micron order silk fibroin powder is applied to cosmetic health product all the time, but because its particle is large, difficult absorption, process can be lost the part nutritional labeling, so its application continuously effective fruit is not good, and constantly the problems such as bad reaction are taken in appearance orally.
New technology fibroin manufacture method is divided into Physical and chemical method.The nanometer silk fibroin powder that physical method makes is slightly soluble in water, do not change itself solid state properties, and can 100% keep original composition and the nutrient of silk fibroin powder, and the solvable nanometer silk fibroin powder that makes with chemical method, human body absorbs easily, but because passed through chemical treatment, the silk fibroin powder self component has had change.Specifically more as shown in table 1.
Silk fibroin powder is in technologic breakthrough, and its particle diameter is promoted to nanoscale from micron order, and it is used also from flush coat, and the is oral beauty functions of Denging is developed to for new material functions such as weaving face fabrics.
Fibroin fiber is a kind of novel functional textile material, has wide market prospects.The fibroin fiber textiles of pushing at present the domestic market to has progressively extended to the fields such as shirt, outdoor activity clothing, jean, socks and bedding from initial knitted underwear, brassiere, T-shirt, pants etc., supply falls short of demand for product.The health care of fibroin fiber uniqueness has caused external travelling trader's concern equally.
Fibroin fiber is the fiber of being made by fibroin powder and the spinning of viscose pulp dope blending, is the gang of new functional fiber, because it has good spinnability, can become with various natural and synthetic fiber blending the textile raw material of all size.
But with regard to present prior art, among the preparation technology, the key technologies such as the reunion of fibroin powder and Stability of Slurry still have to be solved.
