Description
Technical field:
The present invention relates to silk technical field, relate in particular to a kind of finishing technique of anti-yellowing of silk fabric.
Background technology:
Containing a large amount of ultraviolet in sunlight, most ultraviolet can absorb by the ozone layer in air, only have the ultraviolet of about 10% to project on ground.Appropriate ultraviolet radiation is necessary to human body and plant growth, but excessive accept ultraviolet irradiation and can cause problems.
Silk is a kind of natural protein fibre, main containing fibroin, silk gum and other materials on a small quantity, can be there is yellowing in silk fiber under the factor effects such as light, heat, biology, its mechanical property, surface topography, aggregate structure, molecular mass etc. all create change, and the yellowing processes effect of its illumination to silk fabric is larger.
Usually in storage process, yellowing variable color in various degree can all be had, mainly because the amino acid residue such as the tryptophan in fibroin and TYR is oxidized and painted in atmosphere through the silk fabric of refining bleaching.The light yellowing of silk fabric is fibroin macromolecule generation photochemical reaction in essence, namely under light illumination, the temperature of silk fabric raises, and fibroin polymer segment energy of thermal motion increases, molecule segment easily easily ruptures, and cracking goes out the low molecule product of some yellow.Meanwhile, silk fabric surface and internal temperature raise, and produce internal stress, occur warpage and be full of cracks, humidity increases, and silk fiber occurs swelling, volume becomes large, and the intermolecular force of its aggregated structure changes, and change in various degree all occurs for the speed of yellowing and the mechanical strength of silk fiber.
Two kinds are had at present: a kind of is the silk fabric of yellowing is carried out bleaching to make it return to original whiteness, and another kind silk fabric is being carried out to anti-ultraviolet radiation treatment to prevent its yellowing to the yellowing-proof finish of silk fabric.The yellowing-proof finish of silk fabric has ultra-violet absorber, antioxidant, the agent of resin truth, wherein ultra-violet absorber optionally absorbs ultraviolet and is converted to harmless energy, the destruction of ultraviolet to silk can be reduced, the ultra-violet absorber decapacitation with industrial utility value absorbs outside the ultraviolet of specific wavelength, also have good photostability, usefulness is lasting, nontoxic washable.
Summary of the invention:
The object of this invention is to provide a kind of finishing technique of anti-yellowing of silk fabric, the method utilizes the fibroin ethylene glycol diglycidylether aqueous solution and fibroin Nano sol finishing agent, silk fabric is successively immersed in two kinds of solution, improve the anti-uv-ray of silk fabric, yellowing-proof finish is carried out to silk fabric.
Object of the present invention is achieved through the following technical solutions:
A finishing technique for the anti-yellowing of silk fabric, comprises the following steps:
(1) be dissolved in lithium-bromide solution by useless silk, 60-70 DEG C of process 2-3h, obtains silk fibroin protein solution;
(2) mixed with silk fibroin protein solution by the ethylene glycol diglycidylether aqueous solution, the obtained fibroin ethylene glycol diglycidylether aqueous solution, immerses silk fabric in solution, until after silk fabric drenched by dissolution homogeneity, take out and dry;
(3) presoma of titanium, glacial acetic acid, water are mixed, regulate pH value, be stirred to collosol state, then mix with silk fibroin protein solution, obtained fibroin Nano sol finishing agent;
(4) immersed by silk fabric in fibroin Nano sol finishing agent, two leachings two are heat-treated after rolling, and take out washing drying, obtain the silk fabric of anti-yellowing.
Preferred as technique scheme, the concentration of the silk fibroin protein solution described in step (1) is 2-10%.
Preferred as technique scheme, in the fibroin ethylene glycol diglycidylether aqueous solution described in step (2), the content of fibroin is 0.1%-2%, and the content of ethylene glycol diglycidylether is 1%-5%.
