Description
Technical field
The present invention relates to Eider down processing technical fields, more specifically, it relates to a kind of load nano-titanium dioxide antibacterial
The preparation method of natural feather.
Background technique
Natural feather is the abdomen grown in geese and ducks, lupine-like villus, and slabbing is feather.Since natural feather is a kind of
Animal protein fiber, the tiny stomata for ten million triangle that gathers on natural feather nodular fibrous, can shrink with temperature change
Expansion, generates temperature adjustment function, and absorbable human body distributes the hot gas of flowing, completely cuts off the invasion of cool ambient air.From the inspection of fluffy degree
Analyzed in survey, natural feather than silk, the heat insulating materials such as cotton will a high grade, for example 450 degree of minimum standard fluffy
90 duck's downs are also more fluffy than silk and cotton good, so natural feather is purely by way of a heat insulating material, its economic value is much high
In other heat insulating materials.
Currently, Chinese natural feather industry accounts for 70% world market share.Natural feather all has good warming characteristic, can make
For the raw material of down products.But organic substance existing for raw material itself is also easy to produce peculiar smell after long-time breeds bacterium.It is existing
Some antibacterial down feather products are generally the simple doping of antibacterial material, easily cause antibacterial material to fall off, anti-microbial property is held time
It is too short.
Therefore, how to design it is a kind of be not easy to elute, the preparation method for the antibacterial down feather that antimicrobial lifetime is long is that we compel at present
Cut problem to be solved.
Summary of the invention
The object of the present invention is to provide a kind of preparation methods of load nano-titanium dioxide antibacterial down feather, and having makes nanometer two
Organic matter in the hydroxyl reactive group and natural feather of titania surface is effectively compound, can realize under the action of chemical bond solid
It is fixed, it is not easy to elute, extends the effect of antimicrobial lifetime.
Above-mentioned technical purpose of the invention has the technical scheme that a kind of load nano-titanium dioxide
The preparation method of antibacterial down feather, comprising the following steps:
S1: natural feather raw material are chosen, and to stand-by after raw material air blast classification；
S2: being added shampooer for the stand-by natural feather of 1-2kg and wash, and clear water, degreasing agent and fungicide rinsing is then added
20-30mins, rinse temperature are 40-50 DEG C；
S3: after washing, clear water is added and carries out secondary rinsing, rinsing time 10-15mins, controlled at 40-
50℃；
S4: the natural feather after secondary rinsing being gone in dryer and is dried, and drying temperature is 80-100 DEG C, drying time
For 20-30mins；
S5: being added 30-50g butyl titanate and 10L ethyl alcohol in reactive tank, after reactive tank is added in the natural feather after drying
Stirring, is slowly added to 1L distilled water, reacts 20-30mins under conditions of temperature is 60-70 DEG C；
S6: natural feather after reaction is gone in dryer, under conditions of temperature is 80-100 DEG C after drying 1-2h,
Obtain load nano-titanium dioxide antibacterial down feather.
The present invention is further arranged to: in S2 and S3, the weight ratio of the clear water and natural feather is 5-7:1.
The present invention is further arranged to: in S2, the weight ratio of the degreasing agent and natural feather is 2:5-7.
The present invention is further arranged to: in S2, the weight ratio of the fungicide and natural feather is 1:4-6.
In conclusion the invention has the following advantages: using nano-titanium dioxide quantum size effect, attack has
The unsaturated bond of machine object extracts the new free radical of hydrogen atom generation, excites chain reaction, plays antibacterial action；By nanometer titanium dioxide
Organic matter in the hydroxyl reactive group and natural feather on titanium surface is effectively compound, fixation can be realized under the action of chemical bond, no
Easily elution, antimicrobial lifetime extend；Load nano-titanium dioxide antibacterial down feather is prepared by the way that liquid phase is compound, method is simply applicable in, has
Conducive to industrial industrialization, and there is apparent restraining and sterilizing bacteria effect.
