Description
Technical field
The present invention relates to a kind of method of manufacturing anti-bacterial cloth through vacuum ion anchoring technology.
Background technology
Microorganism is ubiquitous at occurring in nature, and is inseparable with the human lives.In the daily life, textiles be these microorganisms well autoeciously.Common microorganism mainly comprises Escherichia coli and staphylococcus aureus etc. on the textiles.Escherichia coli easily cause acute diarrhea; Staphylococcus aureus is modal pathogen in the humanization pyogenic infection.For the mankind's health, people suppress the growth and breeding of pathogenic bacteria by various means, reach the purpose of antibacterial bacteriostatic.Human body is carrying a large amount of microorganisms under normal condition, even can not eliminate these bacteriums through repeatedly washing, situation is just even more serious in particular surroundings, such as certain hospital the bed clothes in ward are detected discovery, cotton-wadded quilt and cotton pad contain a large amount of bacteriums, especially SARS virus in 2003 is promptly propagated from south to north and is endangered in China, make our heightened awareness nontoxic to exploitation, have the importance of the antibacterial fabric of good gas defence antibacterial functions.
The exploitation the earliest and also the antibacterial textile moldproof, anti-odour processing method that always continues into the present be the method for rear arrangement.The reason that this method is generally adopted is because of easy to process to a great extent, and alternative antiseptic wide range.Textiles is no matter be that raw fiber or yarn or fabric even ready-made clothes all can obtain antibiotic effect by rear Collator Mode.Textile manufactures can very optionally select different antiseptic production to have the product of different antibacterial characteristics according to the needs of user or final use, but this method also exists a fatal weakness, and that is exactly that organic products has certain toxicity to human body.
The security of antibacterial fabric is embodied in it when playing the antibacterial and protective effect, and human body is not had toxic and side effect, does not destroy the micropopulation of human normal.Producing and using the purpose of antibacterial fabric is not eliminating bacteria, but the too much breeding of anti-bacteria.Generally speaking, the activity of antiseptic is wider, and senior species are comprised that human toxicity is just larger.Use the chemicals treatment textiles to it is also noted that medicament is to the side effect of human body when reaching antibiotic purpose.
All microbial action agent can both be killed the organic matter that lives, such as bacterium, saccharomycete.These activating agents have various toxicity to mammal.Therefore to producers and consumers's safety effective guarantee to be arranged.Although can utilize inhibitor to reduce to minimum to operating personnel's toxicity, for traditional antimicrobial product, it is difficult and expensive eliminating these noxious materials.
For clothing, the bedding of often washing, washing namely loses antibacterial effect through several times.Although it is crosslinked that some used for textiles have antiseptic and the fiber of active group, still greatly differ from each other from lasting or permanent antibiotic requirement.In addition, processing often causes many cotton knots to bulk fibre, makes the postorder difficult processing to carry out.However because natural fabric is difficult to obtain antibacterial effect by the mode of fibre modification, therefore up to the present, the antibacterial treatment of the textiles made from natural fabric still after Collator Mode be main.
Along with chemical fibre develop and in the fiber consumer field, occupy gradually leading position rapidly, the blending product of various purifying fibres or chemical fibre and natural fabric has become the leading role of all kinds of textiless.Because the easier chemical modification of chemical fibre, thereby people turn to the macromolecular structure modification of fiber and the method for blending and modifying and produce the persistence anti-bacterial fibre, wherein take blending method as main.The early stage antiseptic that is used for the chemical fibre co-blended spinning generally is the compound of metal ion, wherein has many antiseptics to contain heavy metal ion.In recent years, enhancing along with people's environmental consciousness, heavy metal ion causes people's attention gradually to the eco-toxicity problem of human body, good anti-bacterial effect but the larger antiseptic that contains heavy metal ion of toxicity are eliminated gradually, the substitute is some harmless metal oxides, salt or load with active metallic ion on the inorganic non-metallic compound as the main antiseptic of synthetic fiber blending and modifying, as contain Ag zeolite, Zn, Cu compound and TiO2 etc.This class antiseptic has broad-spectrum antimicrobial effect, and is harmless, and Heat stability is good, but also has research to find, there is the defective that persistence is poor, prompt effect is poor and antimicrobial spectrum is wide not in the antibacterial fabric of the co-blended spinning that exists on the market now.Main cause is that selected antiseptic is too single; Antiseptic and textile fiber in conjunction with defective tightness, use and wash easily and the fiber disengaging through long-term, lose antibacterial effect.
Make a general survey of the achievement in research of existing antibacterial fabric, mainly be adsorb, the methods such as spray and blending, antiseptic is attached to fabric face.Can play certain antibacterial action so at short notice, but along with the passing of service time, antibacterial effect descends significantly.Simultaneously, because the antiseptic kind of using is more single, antibacterial effect is also not ideal enough.
Summary of the invention
The purpose of this invention is to provide a kind of method of manufacturing anti-bacterial cloth through vacuum ion anchoring technology, it is achieved through the following technical solutions.
Cloth through vacuum ion anchoring technology is namely under a kind of relatively stable vacuum state, the cathode titanium target, produce glow discharge between silver target and germanium target and anode, the interpolar gas molecule is ionized and produces charged particles, wherein cation is subjected to the negative potential accelerated motion of negative electrode and clashes into the titanium target, silver target and germanium target, the motion of the particle high speeds such as its atom is flown out, this atom that flies out then grappling is embedded in textile fiber inside and forms closely electric conductor, excite and see through, dissociate, ionization ... molecule Deng the reaction generation, atom, the excited state material, electronics, negative ions, free radical, UV light (ultraviolet light), visible light ... Deng material, the state that these materials mix is referred to as electricity slurry Plasma.Under ultra-high vacuum state, with titanium, silver, germanium three metal ion species firmly grappling be embedded on the textile fiber, the antibacterial effect of these three kinds of metals has been contained the viral kind that easily causes clinically infection substantially.
T i-titanium makes organic substance decomposing and has antibiotic, antivirus action based on light-catalyzed reaction.In the water and air system, under sunlight especially ultraviolet irradiation, serial reaction occurs in the hole (h+) that produces electronegative electronics (e one) and positively charged that is activated, and forms hole-electron pair.The H of these hole-electron pairs and its adsorption
2O or OH
-And O
2Effect generates hydroxyl radical free radical OH and superoxide anion radical O
2 -Newly-generated free radical has very strong chemism, particularly elemental oxygen can react (oxidation) with most organic matters, thereby can effectively decompose and destroy airborne multiple toxic gas, but when running into bacterium the cell membrane of directtissima bacterium, cell membrane or intracellular constituent.In addition, these active oxygens also cause the fracture of the phosphodiester bond between the base in the DNA chain, destroy the dna double helical structure, thus the dna replication dna of destroy microorganisms cell and the metabolism of disorderly cell.
There are 3 kinds of Antibacterial Mechanisms in Ag silver type inorganic antiseptic: (1) Ag+ stripping Antibacterial Mechanism: the Ag+ that namely slowly releases is attracted by the microorganism of surface with negative electrical charge, thus the electrolytic equilibrium of destroy microorganisms. make its cell membrane impaired and dead; (2) contact Antibacterial Mechanism: bacterium relies on Coulomb attraction firmly to be adsorbed on the electronegative cell membrane with after Ag+ contact. and further the penetration cell wall enters bacterium inside. with sulfenyl reaction wherein. the activity of destruction cell synzyme. make cell lose the division growth ability and death; (3) photocatalysis antibacterial mechanism: .Ag+ can play the effect of catalytic active center under the irradiation of certain wavelength, thereby makes the hydroxide ion, water and the oxygen that are adsorbed on the antiseptic surface become hydroxyl, the contour active group of active oxygen. and these active groups can act on Bacteria destroyed bacterium tissue. suppress its Growth and reproduction.
The Ge organic germanium compounds is a kind of compound that can regulate immunization in the host that autoimmune function changes, energy inducement interferon, activation NK cell and macrophage.Such as human oral You Machine Germanium 2250mg.Such as human oral organic germanium 2250mg, all Hou Xue Germanium Zhong deterrent Ke Da peak values.But interferon peaking in the blood germanium after the week.Dan Even Continued is down to previous level ， Said Ming Over amount Fu Yong No effect with Drug one Ge month ， The.But continuous use one month then is down to previous level, illustrates that excessive use is without effect.Make Try Examination with mouse, Elixirs amount As 300mg/kg, 20 Xiao Time Hou Gan Interference Su Da be to physiology Yi Righteousness level, the highest Concentrated degree 320 Single position/ml of 24 Xiao Time Ke Da.Test with mouse, dosage is 300mg/kg, and interferon reaches the physiological significance level after 20 hours, can reach maximum concentration 320 units/ml in 24 hours.Try Examination like someone the Chong Complex Class, the Elixirs amount is identical, and 25～30 Xiao Time can arrive 167.1～367.5 Single position/ml.Someone repeats similar test, and dosage is identical, and 25～30 hours can arrive 167.1～367.5 units/ml.48 Xiao Time Hous descend.Descend after 48 hours.Can be increased by Zeng Strong Machine Body De Fang Royal ability ， deterrent by the Yu deterrent, immune Neng Li The adds Strong.Because interferon can strengthen the defence capability of body, interferon increases, and immunocompetence is then strengthened.Organic Germanium has also been reported to take 24 hours， Spleen NK cell activity increases,， Intraperitoneal injection 48 hours， Peritoneal macrophage cytotoxicity occurs,， Those indicated immunity organic germanium can improve the prevention and treatment of various diseases causes.Also have report to take organic germanium 24 hours, the NK cytoactive increases in the spleen, and cytotoxic macrophage appears in lumbar injection 48 hours in the abdominal cavity, and these show that the raising of immunocompetence is the reason that organic germanium could prevent and treat various diseases.
Three kinds of metallic element synergies can effectively solve the prompt effect of antimicrobial product and the problem of durability.Simultaneously, add the germanium metal, can effectively prevent the problem of silver ion chance air oxidation blackening.
Specifically, the method for manufacturing anti-bacterial cloth through vacuum ion anchoring technology of the present invention may further comprise the steps:
1) design on fabric surface is carried out preliminary treatment, said preliminary treatment is to clean with organic solvent and deionized water successively under Ultrasonic Conditions, scavenging period respectively is 5～15 minutes, at last under vacuum condition in 15～85 ℃ of dryings 0.5～3 hour, said organic solvent is the mixed liquor of acetone and ethanol; But the cloth pollutant is removed in said preliminary treatment also choice for use electrophoresis.
2) in the container that titanium target, silver-colored target and germanium target are installed, be filled with inert gas, utilize vacuum equipment to make container inner pressure drop to vacuum 10
-1～10
-5Torr passes into oxygen gas, and the control container inner pressure is that 1～10 mtorr, temperature are 20～250 ℃, and preferred 100～200 ℃, direct current is passed into titanium target, silver-colored target and germanium target with predetermined power, produce the discharge of electricity slurry;
Said inert gas is argon gas or nitrogen, said galvanic voltage: 300～800V, preferred 300～500V, current density: 4～60mA/cm
2, power density: 1～40W/cm
2
In order to improve ultrahigh vacuum deep layer ion grappling efficient, setting is parallel to the magnetic field on titanium target, silver-colored target and surface, germanium target target source to said vesse, can be with the movement limit of the initiating electron zone at adjacent cathodes, thereby the ionization efficient of enhancing gas atom, said magnetic field intensity are approximately: 50～300Gs; Catch electronics by externally-applied magnetic field, prolong and fettered the motion path of electronics, improved ionization level, increased textiles deep layer ion grappling speed;
3) cloth is at the uniform velocity passed through titanium target, silver-colored target and germanium target to furl mode, make three metal ion species be anchored on fibrous inside and outer rim; The maximum deposition rate of titanium target, silver-colored target and germanium target is 100nm/min～1000nm/min;
The target source of titanium target, silver-colored target and germanium target is divided into balanced type and unbalanced, and the source grappling of balanced type target is inlayed evenly, and the source grappling of unbalanced target is inlayed with basal body binding force strong.Balance target source is used for hollow textile class textiles, and is non-equilibrium for solid chemical fibre textile.Negative electrode distributes different according to magnetic field configuration, be divided into equilibrium state and non-equilibrium negative electrode.The magnetic flux of equilibrium state negative electrode internal-external magnetic steel about equally, bipolar magnetic line of force closure is in target surface, well with electronics/plasma confinement at the titanium target, near the target surface of silver target and germanium target, increase collision probability, improved ionization efficient, thereby just can build-up of luminance under lower operating air pressure and voltage and keep glow discharge, make the titanium target, the utilization rate of silver target and germanium target is relatively high, but because electronics moves main closure in target surface along the magnetic line of force, the suffered Ions Bombardment in textiles zone is less, namely allow negative electrode outer magnetic pole magnetic flux greater than internal magnetic pole, the bipolar magnetic line of force is not exclusively closed at target surface, the part magnetic line of force can extend to along the edge of target the textiles zone, thereby portions of electronics can expand to textiles along the magnetic line of force, increase plasma density and the gas ionization rate of textiles. no matter balance/unbalance, if magnet is static, its magnetic signature determines the titanium target, the target utilization of silver target and germanium target is less than 30%.
Bombarded high-velocity particles motion easily with metal alloy, this is because the source target (negative electrode) of titanium target, silver-colored target and germanium target, plasma, and can be formed the loop by textiles.Metallic target is used in the ultrahigh vacuum deep layer ion grappling that we adopt exactly, adds argon gas and reacting gas such as nitrogen or oxygen, owing to Conversion of Energy, generates nitride or oxide with reacting gas chemical combination when metal targets hits textiles.
The ion grappling is stable to be carried out in order to make, preferably the target source is cooled off, because in ion grappling process, produce amount of heat, if not enough without cooling or cooling, this heat will make the target source temperature of titanium target, silver-colored target and germanium target raise, even dissolve the target source, therefore adopt recirculated water cooling mode cooled target source.
4) cut cloth, car limit, vacuum packaging;
5) cloth is delivered to radiation irradiation center, again degerming and bacterium colony.
The characteristics of antibacterial cloth of the present invention:
(1) high security, without any side effects.
(2) without stripping property, do not enter human body, adopt the absorption system anti-bacteria and anti-virus, better durability is arranged.
(3) broad spectrum antibacterial, the kind of metal ion is different, and various bacteria and virus are had good inhibition.
(4) do not develop immunity to drugs.
(5) good heat resistance, repeatedly heated scrub.
Generally speaking, from physical property, the slow stripping of antibacterial cloth antibacterial material of common dissolution type, reach antibacterial action, this antiseptic cost is lower, antibacterial effect is fine, but the bacterium in the fabric and the bacterium on the skin can be killed without exception, can destroy the microecological balance of skin surface microorganism, and antibacterials are also easily invaded application on human skin and blood vessel from the fine hair hole of human body, continuously long-time use might reduce body immunity and produce drug resistance, so no matter still consider from durability from security, this antiseptic is not optimal selection.The textile cloth that the present invention adopts ultrahigh vacuum deep layer ion grappling technology to produce, security can be rated as first-class, only kill the bacterium on the skin that bacterium in the fabric and fabric fibre can touch, suppress the harmful bacteria breeding, thereby can not destroy the microecological balance of skin surface microorganism, have security and durability.
