Description
The present invention relates to a kind of method of making soybean milk composite fibre with soybean protein, milk protein and polyvinyl alcohol.
Along with people's living standard improves constantly, the requirement of garment material is developed towards multi-level, many kinds direction.In the world current, occurred that Piao returns very to returning aspect dress, the pursuit of uphold nature, comfortable healthy aspect, market is bigger to the demand of natural fabric.For adapting to this piece market new demand, will force us to develop the fabric raw material of high-performance, high-quality, high technology content.
Utilize the native protein azlon, proposed several different methods at present.Spinning the milk protein silk of being called of company exploitation " Star ノ Application " (glad you) fiber as Japanese Japan, is the composite fibre by the acrylonitrile compolymer of about 40% milk casein and 60%.China's publication and for example provides respectively in the application number 95111366.6,96116532.4,94114071.7 with pupa albumen, milk protein and fibroin and the blend of synthetic high polymer raw material propylene nitrile, acrylamide or polyacrylonitrile, the manufacture method of copolymerized fiber.It is the method for raw material production soybean protein composite fibre that China also has with the glycinin.Also have my patent applied for (application number: 01106274.6, open) milk protein and polyvinyl alcohol composite fiber manufacture method in addition.
For further making protein fibre product diversification, seriation, meet the need of market better, the invention provides a kind of is raw material with soybean protein, milk protein and polyvinyl alcohol, produces the method for soybean milk composite fibre.
The method of the manufacturing soybean milk composite fibre that the present invention relates to comprises: the dissolving of (1) soybean protein and milk protein, modification; (2) washing of polyvinyl alcohol and dissolving; (3) protein solution and poly-vinyl alcohol solution redox system initator, the initiation grafting copolymerization; (4) wet spinning is made soybean milk composite fibre.
At first, get soybean protein and milk protein, press soybean protein isolate 30～70%, the mixed of milk protein 30～70% adds deionized water, is 10～20% with the mass percentage content of dilute NaOH solution furnishing protein, PH is 9～13.5 protein solution, and to add the liquor capacity percentage composition be that 0.5～1% concentration is 36% hydrogen peroxide, is heated to 80～120 ℃, stirs to dissolve fully to protein in 2～4 hours.
Polyvinyl alcohol is washed, is dissolved according to the known vinylon production technology in synthetic fiber field, is mixed with the polyvinyl alcohol water solution of 10-20%.
With the protein and the polyvinyl alcohol of dissolving, the weight ratio of pressing dry is (20～50): (50～80), send into after filtration respectively in another reactor, mixed 30～60 minutes.Add oxidation-reducting system initiator then, and to transfer pH value with dilute sulfuric acid be 2～3, insulation was stirred polymerisation 1～2 hour at 60～90 ℃, made protein and polyvinyl alcohol graft copolymerized copolymerization.Wherein: oxidation-reducting system initiator can be selected for use: NaClO

With graft copolymerization solution, be heated to 98 ± 2 ℃, send into deaerator after filtration, static and keep 98 ± 2 ℃ of temperature, deaeration 6-10 hour, make the spinning solution of spinnability.
Filtration in the said process when small scale experiments, can be used candle filter or dish-shaped filter; Use plate and frame type filter-press during industrial production.Its filtering material uses three layers of polyvinyl single-side pile and one deck Kanakin.
Spinning solution after the deaeration utilizes the spinning process of the known vinylon in synthetic fiber field and equipment to carry out spinning, drawing-off, dryness finalization, acetalation arrangement, makes soybean milk composite fibre.
Characteristics of the present invention are: cheap, the wide material sources of soybean protein raw material, milk protein make the fiber feel smooth, soft; The composite fibre that generates has good hygroscopicity, gas permeability and dyeability, and comfortable and easy to wear smooth, skin-friendly is good; Can make full use of the production equipment of domestic vinylon plant, suitably increase protein dissolution equipment, can produce after the transformation, small investment, instant effect.
Present invention will be further described for following example, but can not think to limit scope of invention.In these examples, deal and percentage are by weight, unless other explanation is arranged.
Example
Take by weighing soybean protein and milk protein and (press soybean protein isolate 50% for each 1.2 kilograms, the ratio of milk protein 50%) mixes, add 12.5 kilograms of deionized waters, mass percentage content with dilute NaOH solution furnishing protein is 15～16%, pH value is 15 kilograms of 12 mixed liquors, and to add concentration be 36% hydrogen peroxide 100ml, is heated to 90～95 ℃, stirs to dissolve fully to protein in 2～4 hours.
15～16% polyvinyl alcohol water solution is washed, dissolves, is mixed with to polyvinyl alcohol according to the known vinylon production technology in synthetic fiber field.
With the protein solution and the poly-vinyl alcohol solution of dissolving, be 30: 70 by weight, send into after filtration in another reactor respectively, mixed 30 minutes.Add oxidation-reducting system initiator K then
