Nano particle used herein is a nano SiO 2 particle, and it carries out modification to give the user specified property of expectation by adding metallic molecule such as aluminium, silver, copper, nickel and gold.These performances comprise that water-repellancy, antimicrobial acivity and surface tension change.
Metal-modified nano SiO 2 particle is by with nano particle with comprise metal ion solution and mix and to prepare.Such solution is normally by being dissolved into metallic compound in the solvent, forms the free metal ion and make in this solution.Because potential difference, described metal ion is sucked out and is adsorbed onto on this nano particle.The further discussion of modified by nano particles can be found in the U.S. Patent application of submitting on April 30th, 2,002 10/137052, and it is hereby incorporated by.
Can utilize many technology between this transition metal and silica dioxide granule, to form stronger chemical bond.For example, it has been generally acknowledged that silicon sol at pH greater than about 7, be stable when particularly pH is for 9-10.When water-soluble, the salt of transition metal is tart (for example cupric chloride has about 4.8 pH).Therefore, when so acid transition metal salt mixed mutually with alkaline silica sol, pH was lowered, and metal salt precipitate is to the surface of silica dioxide granule.This injures the stability of this silica dioxide granule.In addition, under lower pH value, the reduced number of the silanol that on this silica particles, exists.Therefore because transition metal is attached on these silanol, this particle has been lowered in conjunction with the ability of transition metal under lower pH value.Also metal and silica dioxide granule bonding may be formed " coordination " and/or " covalent linkage ", this can have multiple benefit, as has reduced that any metal will keep the free possibility as described in use (for example after cleaning).
Because the pH that the adding of acid transition metal salt (for example cupric chloride) causes reduces the influence of effect, what can expect is in order to improve, with transition metal mixing process in, to the selective control of carrying out of silica dioxide granule pH.Selective control to pH can be by using any finishing in the multiple known buffer system known in the art.
Many suitable metal-modified nano SiO 2 particles are commercial obtainable.These comprise from Tokyo Nissan Chemical Industries, Ltd., SNOWTEX_-C, the SNOWTEX_-AK of Inorganic Material Division and SNOWTEX_-OXS nano particle.
Generally speaking, described silane coupling agent can be covalently attached on the silica dioxide granule by the silanol (Si-OH) that is present on the silica particles.Particularly, the Siliciumatom of this silane coupling agent can form covalent linkage with the oxygen of silanol.In case this silane coupling agent is covalently bound to silica dioxide granule, this organo-functional group just can form coordinate bond with transition metal.For example, copper can form coordinate bond with the different amino group that exists in the aminopropyl triethoxysilane coupling agent.Silane is well known in the art differing materials to be bonded to useful coupling agent on glass.For example, silane coupling agent is used in for a long time in the glass industry to add between the resin that wherein plays enhancement on the glass surface with glass and is formed chemical bond.In this bonding, generally believe between the Siliciumatom of the Siliciumatom of silane coupling agent and glass to form chemical bond or sucking action, and form chemical bond or sucking action between the hydrocarbon of this silane coupling agent part and this hydrocarbon resin.This covalent bonding theory is further shown at Edwin P.Pluedemann Silane Coupling Agents,Plenum Press, NY, NY, 1991 second editions make further research in the 18-22 page or leaf.Therefore, some surprisingly silane coupling agent will improve or improve the China ink color fastness.

There are many methods that China ink is administered to fabric can be used in the practice of the present invention.Can use any other suitable method that well known to a person skilled in the art.Exemplary non-exclusive method comprises the preceding measuring system and the back measuring system of following concise and to the point description:
Preceding measuring system (China ink of initial use is inexcessive):
Slit mouth mould: this method is used the pressure head that wherein has slit.The coating material metering is passed through this slit directly to ground.
Directly intaglio printing: coating is in the loculus in the intaglio printing roller.Ground directly contact with this intaglio printing roller and with the pigment transfer in the loculus to ground.
Have the offset printing intaglio printing that contrary roller shifts: similar with direct intaglio printing, except the intaglio printing roller arrives the another one roller with pigment transfer.This second roller contacts with ground then.
Curtain coating: this is a kind of dispense tip that wherein has a plurality of slits.The different coating materials meterings of forming are by these slits and with before ground contacts, the given distance of dripping.
Slide (stepwise) be coated with: this method is similar to curtain coating, except multi-layer coated material from the dispense tip ground that comes out directly to contact.Between dispense tip and ground, there is not open gap.
Front and back roller coat (being also referred to as the transfer roller coating): this is made up of a pile roller, and its purpose for metering is transferred to next roller with coating material from a roller.Last roller contacts with ground.It is the sense of rotation that roller coat cloth or reverse roll coating forward will be depended on the travel direction and the last roller of ground.
Extrusion coated: this technology type is similar to slit mouth mould, except coating material at room temperature is solid-state.Material is heated to melt temperature and passes through slit directly to ground as liquid meter in dispense tip.By cooling, this material becomes solid again.
Roto-sifter: coating material is pumped in the roller with sieve surface.Scraper plate in this roller extrudes coating material through this sieve, then it is transferred to ground.
Nozzle is used: the coating material pressurized directly is sprayed onto on the ground by nozzle.Can apply the coating (preceding metering method) of desired amount.Perhaps ground can ooze by nozzle is full, then any unnecessary material is extruded (back metering method) by mip rolls.
Flexographic typography: the raised design surface of coating material being transferred to roller.This then pattern roll is transferred to coating material on the ground.
The printing of digital textile product: coating or printing ink are in the ink-jet tube.The fabric ground is delivered under this printing ink gun, China ink is sprayed onto on this ground makes printed images.
Back metering when initial (use excessive China ink, remove subsequently):
Rod is coated with machine: coating material is administered to substrate surface and uses rod that unnecessary material is removed.The Mayer rod is to be mainly used to measure the method for removing these unnecessary coating.
Air knife blade coating: coating material is administered to substrate surface and removes unnecessary coating material by using high-pressure air that it is purged.
Blade coating: coating material is administered to substrate surface and excess stock is removed by cutter structure head.
Scraper coating: coating material is administered to substrate surface and excess stock is removed by flat scraper structure head.
Dip-coating (infiltration) is followed by extrusion roll: ground is immersed in the used material.Then saturated ground traction is squeezed out unnecessary material by two rollers.
Spin coating: make applied ground high speed rotating.To also unnecessary material be thrown away the edge on the ground of this rotation of coating material paint.
The damping coating: coating material is by on the quilt damping head paint ground of filling with.Unnecessary material is removed by scraper.
Brush: coating material is by on the brush paint ground.Unnecessary material is controlled along moving of substrate surface by this brush.
In order to improve the crocking fastness of China ink, printed fabric then must be by " curing ".Curing is the process that this fabric is exposed to the environment of enough humidities under the temperature and time that is enough to make crocking fastness to increase.The type and thickness and the environmental factors that depend on the textiles ground are solidificated in about 150-200 ℃ and carry out the sufficiently long time.For example cotton is in 3 minutes set time of 180 ℃ of needs.Nylon is 150 ℃ of needs 3 minutes, and PET is in 3 minutes set time of 180 ℃ of needs.(should be noted that this time is proximate)
