The invention discloses a kind of method for bleaching of soybean fiber, by the way that soybean fiber is first irradiated with ultraviolet light, the soybean fiber of irradiating ultraviolet light is bleached with hydrogen peroxide again, then white goods washed, dry acquisition bleaching finished product, ultraviolet light destroys in soybean fiber the pigmentary structures for being difficult to remove during hydrogen peroxide bleaching, substantially increases the bleaching whiteness of soybean fiber fabric.The bleaching for realizing high whiteness soybean fiber fabric by the method for the present invention is processed, the indices such as the whiteness of blanching soya beans azelon fabric, strength, dyeability meet the requirements, the whiteness of soybean fiber fabric is the method increase, guarantee is provided for the bright color of soybean fiber fabric, light color, iridescent dyeing.
Description
Technical field
The invention belongs to dyeing and finishing technique field, is related to a kind of method being combined using ultraviolet light and hydrogen peroxide bleaching
The method that soybean fiber obtains high bleaching whiteness is realized, can especially realize soybean fiber light color, bright color and fluorescence
The dyeing of color.
Background technology
Soybean fiber is a kind of azlon comfortable and easy to wear, soft, good hygroscopicity, its knitted fabric
It is the preferable fabric for making underwear and children's garment.But soybean fiber causes because of the presence of isoflavones, and its whiteness is very low, yellowing
Very high, the Oxidizing and Reducing Agents such as conventional hydrogen peroxide bleaching process is difficult to obtain high bleaching whiteness, it is difficult to meets light, fresh
The dyeing process of gorgeous color and iridescent.
Patent of invention CN 1277018C disclose the method that a kind of soybean fiber elder generation reducing bleach reoxidizes bleaching,
The B of patent of invention CN 103173992 disclose a kind of method of soybean fiber hydrogen peroxide and bleach-activating bleaching, hair
The bright A of patent CN 105484010 disclose a kind of soybean fiber and first use hydrogen peroxide bleaching, then white goods is entered with daylight
The method of row irradiation, above-mentioned soybean protein fiber bleaching method can improve the whiteness of soybean fiber fabric, have no at present
Bleaching, which is successively carried out in two steps, on soybean fiber ultraviolet light and hydrogen peroxide obtains the high report for bleaching whiteness method.
The content of the invention
The technical problems to be solved by the invention are using conventional oxidation and reduction drift for current soybean fiber
Whitening method is difficult to obtain high bleaching whiteness, it is difficult to realizes soybean fiber light color, bright color and iridescent dyeing process
Shortcoming, there is provided it is a kind of by being first irradiated the method bleached again with hydrogen peroxide with ultraviolet light to soybean fiber, it is real
The dyeing and finishing processing of the existing high bleaching whiteness of soybean fiber.
In order to solve the above technical problems, the present invention uses following technical scheme：
A kind of method for bleaching of soybean fiber, is first irradiated using ultraviolet light to soybean fiber, then with chemistry
Bleaching agent is bleached to the soybean fiber through ultraviolet light, finally by soybean fiber washing, the baking after bleaching
It is dry.
The ultraviolet light intensity is 200-1000W, irradiation time 2-20min.
The prescription of the chemical bleaching agent is：Hydrogen peroxide 3-10g/L, sodium metasilicate 2-7g/L.
Described bleaching temperature is 70-100 DEG C, bleaching time 20-100min.
Beneficial effects of the present invention：The present invention provides one and used again by being first irradiated to soybean fiber with ultraviolet light
The method that hydrogen peroxide is bleached, realize the dyeing and finishing processing of the high bleaching whiteness of soybean fiber.Ultraviolet light destroys greatly
It is difficult to during hydrogen peroxide bleaching the pigmentary structures removed in legumin fiber, substantially increases soybean fiber fabric
Bleach whiteness.The bleaching for realizing high whiteness soybean fiber fabric by the method for the present invention is processed, blanching soya beans protein fiber
The indices such as the whiteness of dimensional fabric, strength, dyeability meet the requirements, and the method increase the white of soybean fiber fabric
Degree, guarantee is provided for the bright color of soybean fiber fabric, light color, iridescent dyeing.Technical scheme technique
Simple possible, to raw material, auxiliary agent, fabric without particular/special requirement, large-scale production is achieved that using conventional printing and dyeing mill's bleaching equipment,
Have broad application prospects.
