Description
Technical field
The present invention relates to textile garment Material Field, and in particular to a kind of fiber garment material of antimicrobial health care function and its
Preparation technology.
Background technology
Functional form dress materials refer to having health care, treatment, magnetic concurrently on the basis of the general utility functions of ordinary garment materials
Property, the dress materials of the specific function such as luminous, heating.Wherein, the functional form dress materials of antibiotic health care can obtain prevention disease
Infection, it is mould proof de-taste, sanatory effect, the personal clothing that is particularly suitable for use in, footgear, mouth mask etc. directly contact human body skin and
The dress-goods of organ.
The functional form dress materials of antibiotic health care be added in ordinary garment materials with bactericidal bacteriostasis into
Point, in wearing process, these are slowly released into branch's continuation.Nano level silver metal particles (the general 25- of particle diameter
50nm) it is a kind of disinfecting antipathogenic composition for attracting attention very much in recent years, is also obtained among functional form dress materials
More and more extensive application.Nano-Ag particles have advantages below：First, there is the bactericidal and bacteriostatic effect of broad spectrum activity, to drenching ball
Hundreds of bacterium such as bacterium, Chlamydia, Escherichia coli works, and sterilizing ability is notable；Next to that drug resistance is not produced, to alleviating
The present situation of antiseptic abuse is significant；3rd is that totally nontoxic is tasteless non-stimulated, will not trigger allergic, is not had to human body
There is side effect；4th is also to have the function that to strengthen Cell growth ability, improve microcirculation, and is permeable to subcutaneously, therefore
Be advantageous to anti-inflammatory, wound healing and damaged skin reparation.
In the prior art, among the manufacture craft of functional form dress materials, simplest is directly to spray functional component
Apply or compress is on dress materials surface；Or dress materials are impregnated among the solution containing functional component so that function
Composition is attached to the surface of dress materials fiber.But the compatibility of nanometer silver metal particles itself and dress materials fiber compared with
Difference, absorption affinity each other is very weak, though and nanometer silver metal particles are nanoscale, than molecule particles again it is obvious more
Greatly, when therefore using with upper type, nanometer silver metal particles easily come off from dress materials；Particularly personal clothes want frequent water
Wash, more exacerbate the loss of nanometer silver metal particles.Another factor is that the silver metal for being directly exposed to surface is easy to aoxidize,
Once the beneficial effects such as oxidation antibacterial will disappear.The reason for the two aspects, to use the Nano Silver work(produced with upper type
Energy type dress materials are quickly invalidated.
It is existing it is another make functional form dress materials method be：Function fiber type is made first, then again with work(
Energy fiber type textile garment material, or utilize function fiber type and other fiber blend dress materials.Function fiber type be
Dissolving either adds dissolved state or graininess among the spinning solution such as the cellulose of molten form, silk-fibroin, high polymer
Functional ingredients, then carry out throwing and sizing with spinning process.But nanometer silver metal particles must be with bacterium or skin
Directly contacting competence exertion, it is acted on；Because the charge adsorption that bacterium is carried by silver metal particles when directly contacting, and then by
Its silver ion discharged kills；The silver ion of nanometer silver metal particles release in the state of direct skin contact with that could permeate
Its effect for promoting cell growth is played in skin.And added according to the preparation technology of above-mentioned function fiber type, the overwhelming majority
The organic principle that can be spun into liquid of silver metal particles firmly coat and be sealed in fibrous inside, without directly contact bacterium and
The chance of skin.Therefore, the Nano Silver functional form dress materials DeGrain of above method production, noble metal raw materials consumption
Also meaningless increase.
Chinese patent application CN102392347A discloses a kind of Intelligent silver-contained antibacterial fiber, using doughnut as shell,
In the sandwich layer that the empty intra-bladder instillation argentiferous hydrogel of doughnut is formed；Simple substance containing 0.1%-10% among argentiferous hydrogel
Silver.Because argentiferous hydrogel is covered by inside hollow fibre, it is not easy to aoxidize, elemental silver will not also depart among fiber；
When meeting water in use, the water swelling of argentiferous hydrogel and from the open end expansion of doughnut, so as to realize pair
The elemental silver release of surrounding environment.But the functional component used in above patent is argentiferous hydrogel, rather than effect is more excellent
Silver metal particles；Moreover, quite a few elemental silver is closed in inside hollow fibre all the time and can not discharged, release efficiency is inclined
Low, the effect of bactericidal is restricted.
It can be seen that still lack a kind of functional component using nanometer silver metal particles as bactericidal in the prior art, and
And realize that nanometer silver metal particles are combined with fibre compact and be not easily disconnected from, be advantageous to the high efficiency use of Argent grain and fully release
Put and the antibacterial functions type dress materials of silver metal particles Quick Oxidation can be prevented.
