Abstract
A sterilizing antivirus fabric with super amphophobic nature features that the super amphophobic layer and the sterilizing layer are coated on one or two surface of said fabric. Its preparing process and the medical clothes made of it are also disclosed.
Description
Technical field
The invention belongs to the medical protective material field, particularly ultra-amphosphobic sterilizing disease-preventing poison fabric and method for making thereof, and this ultra-amphosphobic sterilizing disease-preventing poison fabric is used to prepare medical patient's gown.
Background technology
Hospital is the place of curing the sickness to save the patient, and all kinds of sufferer personnel are also carrying various bacteriums and germ, therefore very easily causes cross infection, brings huge threat for people's health.The use of medical protective material provides to the personnel that work in this environment avoids germ invasion and attack, convenient safe safeguard measure.People use protective materials setting " filtration barrier " together, and the harmful substance that environment brought is played the filtration buffer action, make bacterium, virus and various harmful materials etc. can not enter human body.Because some germ is very indomitable, and mainly by body fluid, transmitted by droplets and direct contact, thus require protective materials will possess the killing pathogenic bacteria function, and kill the bacterium ability and be eager to excel and just can reach good protection effect.
Super two thin fabric, its surface has the function of super-hydrophobic and super oleophobic.This function can stop each pseudo body fluid (as blood, sputum, excreta etc.) to infiltrate the opposite side of fabric, thereby has effectively stoped the diffusion of bacterium and virus; Simultaneously germ can be prevented, and condition and the chance that bacterium grows up and breeds can be avoided offering attached to fabric face.
Nano-TiO
2Photochemical catalyst has the function of kill bacteria, because its specific area is bigger, when running into bacterium, at first with the germ adsorption filtration on its surface, the cell of directtissima bacterium subsequently causes the organic matter degradation in the bacterial cell, with this kill bacteria, and make it to decompose.Nano-TiO
2It is high and lasting that the photo-catalyst agent has antimicrobial efficiency, and good advantages such as security.Utilize natural daylight, normal temperature and pressure to get final product catalytic decomposition germ and pollutant, wide accommodation.
Studies show that TiO
2The photo-catalyst agent is to staphylococcus aureus, Escherichia coli, and bacillus subtilis and streptococcus mutans all have higher sterilizing rate, even cancer cell can be killed.Nano-TiO
2Also different mould (as aspergillus flavus, aspergillus niger, Sai Shi aspergillus, Aspergillus terreus, aspergillus ustus, Chaetomium globosum, multi-trunk natalensis, Penicillium citrinum, Paecilomyces varioti, Trichoderma viride) also there is the good sterilization effect.
Inorganic antiseptic has contact-type, broad-spectrum antiseptic, and lasting, water-fast, acid and alkali-resistance are harmless to the health, characteristics such as non-secondary pollution, are widely used at present.As its antibiotic mechanism of silver ion is that silver ion carries out haptoreaction, causes the total composition of microorganism to destroy or produce dysfunction.When the silver ion of trace arrives the microbial cell film, because of the latter electronegative, rely on Coulomb attraction, make both firm adsorption filtrations, silver is from entering in the born of the same parents in the penetration cell wall, and with the sulfydryl reaction, make protein coagulating, destroy the activity of cell synzyme, cell is lost the division growth ability and death.Silver ion can also destroy microorganisms electric transmission system, respiratory system and substance delivery system.
Summary of the invention
One of purpose of the present invention provides a kind of ultra-amphosphobic sterilizing disease-preventing poison fabric, with the cross infection problem between the present patient of hospital of better solution, provides a kind of dress materials of highly effective and safe for vast patient.
Two of purpose of the present invention provides ultra-amphosphobic sterilizing disease-preventing poison process for making such fabric.
Three of purpose of the present invention provides the patient's gown with the malicious textile of ultra-amphosphobic sterilizing disease-preventing comfortable and easy to wear, well behaved hospital.
Four of purpose of the present invention provides ultra-amphosphobic sterilizing disease-preventing poison fabric and is used to prepare medical personnel's safety device.
