Description
Technical field
The invention belongs to a kind of processing method of eider down, be specifically related to a kind of preparation method of self-cleaning function eider down.
Background technology
Down products has shown unique fluffy insulation performance because of its impayable natural fabric advantage, the favor of the person that is subject to market and consumption.
In use, sweat and other dirts contact with eider down down products, and cause eider down to go mouldy, give off a peculiar smell, microorganism exceeds standard; To down products rinsing process, by the fluffy performance of damage eider down and warmth retention property; And a small amount of pathogen that eider down itself carries is in rinse cycle, is difficult to eradicate, affects the comfort of down products.The particularly public down products in hotel, bacteria breed phenomenon is more obvious.
How provide sustained anti-microbial, antiviral to society, environmental protection, ecological down products is that pendulum is at eider down manufacturing enterprise serious and urgent task at the moment.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of preparation method of self-cleaning function eider down, the self-cleaning function eider down of production has water and oil repellant function, has from degradation function the organic pollution be infected with on eider down.
The preparation method of a kind of self-cleaning function eider down provided by the invention, comprises the following steps:
(1) light degradation system is prepared: sulfonated polyether-ether-ketone solution and fibroin polypeptide powder solution are heated and mix, add hydrochloric acid, regulator solution pH to 5.5, the light degradation system of obtained sulfonated polyether-ether-ketone and polypeptide;
(2) submersion dehydration: be impregnated in by eider down in the light degradation system aqueous solution of sulfonated polyether-ether-ketone and polypeptide, adopts two leaching two dewatering process;
(3) finishing agent is sprayed: dried by the eider down after submersion dehydration, water-refusing oil-refusing finishing agent emulsion evenly sprayed on eider down in drying course, obtained self-cleaning function eider down.
Sulfonated polyether-ether-ketone solution concentration 50-150g/L, fibroin polypeptide powder solution concentration 15-50g/L in step (1).
In light degradation system obtained in step (1), the mass ratio 1:1-2.5 of fibroin polypeptide powder and sulfonated polyether-ether-ketone.
Sulfonated polyether-ether-ketone preparation method in step (1), comprise the following steps: dried polyether-ether-ketone is dissolved in 98% concentrated sulfuric acid, solution is poured in 6-10 times of volume frozen water, stir, leave standstill, sediment is centrifugal, washing, filter, repeats 3 times, with alkali lye adjustment pH to 7, vacuumize obtains sulfonated polyether-ether-ketone, wherein the mass ratio 1:80-100 of polyether-ether-ketone and 98% concentrated sulfuric acid.
The mixing of heating described in step (1), heating-up temperature is 60-80 DEG C.
In step (2), two leaching two dewatering process are: flood 8-10min, it is 180-200% that dehydration controls liquid carrying rate at every turn.
Spraying in step (3) and arranging dosage and eider down mass ratio is 2-5:1000.
