Abstract
A fabric for the biological protecting clothing used by medical people is composed of an internal hydroscpic knitted fabric layer, a thermoplastic polyurethane film layer as sandwich layer with monidirection moisture permeability, and an external surface fabric layer. Its advantages are high effect to prevent the infection of virus, especially SARS virus, and bacteria to human body, and durable antibacterial action.
Description
(1) technical field: the present invention relates to medical protective garment, be specifically related to the pre-anti-virus of a kind of medical worker, especially prevent the biological protection clothes lining of SARS (SARS) virus infection.
(2) background technology: medical protective garment of the prior art is mainly used in medical worker's wearing in the hospital ward, to realize preventing infection and the infringement of the virus spread (as SARS virus) of surrounding environment to the medical worker.Common described protective garment fabric adopts rubber or polyethylene (PE) coated fabric or polyurethane (PU) the coated fabric formation of multilayer mostly.It exists not enough: the one, and the protective garment fabric poisture-penetrability is poor, in the ward, work in the higher environment of temperature, it is tight, close airtight that the protective clothing that the medical worker dresses need wrap up health, wearing work for a long time, the a large amount of sweat that produce in medical worker's body can't be discharged by protective clothing, often occur uncomfortable in chest even generation health collapse phenomenon, reduced medical worker's operating efficiency, long-term work causes body immunity to descend, and has had a strong impact on medical worker's physical and mental health.The 2nd, the protective garment fabric biocidal property is poor, protective garment fabric in the market is to adopt the saturating moor reason of pore type, because airborne virus is gluey state and connects, its particle diameter is suspended in the air in the nanoscale scope, the virus infection human body normally wets micropore permeation in human body thoroughly along protective clothing, people wear the protective clothing that this lining is made, and the danger that is subjected to virus infections is big especially.In addition, do not contain antibacterial material in its lining, used protective clothing is sterilized and can only be adopted traditional mode---and the antibacterial processing that carries out disinfection on the protective garment fabric surface often makes the residual virus in the protective garment fabric can not get thorough dissipation.The 3rd, the protective clothing of repeatedly using is scrapped the after stain environment, and protective garment fabric is to be made by PE, PU material, burns the back and produces a large amount of dense smoke contaminated airs; As it being embedded in the underground layer, without putrefaction all the year round, do not degrade, polluted land resource.The deficiency of above-mentioned technology, give our lining manufacturer propose one very urgent and need problem anxious to be solved.
(3) summary of the invention: the present invention is directed to above-mentioned deficiency, purpose is to provide the biological protection clothes lining that a kind of wet perspire is strong and sterilization effect has the environmental protection characteristics significantly again.
For achieving the above object, the technical scheme of protective garment fabric of the present invention is achieved in that between overlapping continuous suction knitted cloth and outer shell fabric, applies gummed and is connected with the TPU moisture-permeable film.
When implementing technique scheme, select TPU (thermoplastic polyurethane) moisture-permeable film to constitute usually by the nanometer-level silver series inorganic antibiosis material.Also can select the TPU moisture-permeable film to constitute for the nano grade titanium series inorganic antibiosis material.Described TPU moisture-permeable film thickness is chosen between the 10-20 μ m usually.Described suction knitted cloth is an areolation.
Lining of the present invention is taked above-mentioned three layers of composite-like structure, the moisture-permeable film that utilizes TPU (thermoplastic polyurethane) material to constitute has the characteristics of unidirectional wet perspire, the medical worker puts on the protective clothing that this lining is manufactured, the sweat that health produces can in time be expelled on the outer shell fabric of protective clothing by the TPU moisture-permeable film, feel that body and mind is comfortable, improved medical worker's operating efficiency.Adopt the saturating moor reason of heat conduction atresia hydrophily, can also stop virus (especially SARS virus) penetrating and, ensured medical worker's physical and mental health effectively composite material to the infecting of human body.
Lining of the present invention through the Ministry of Public Health of the General Logistics Department of PLA, Military Medical Academy microorganism epidemic research institute of PLA, chemical defence research institute of PLA one etc. unit detect proof: SARS virus (80-100nm) and poliovirus (27nm) in the natural microorganisms of biological protection clothes lining in can 100% filtered air, powdered biological particle (spores of bacillus subtilin), the liquid.Because the present invention has added nanometer-level silver system or titanium series inorganic antibiosis material in the TPU moisture-permeable film, through above-mentioned unit test experience: the TPU moisture-permeable film has stronger antibacterial action to colon bacillus, staphylococcus aureus, Candida albicans etc., and this antibacterial lasting effect is long-term, has thoroughly changed the way that the antibacterial processing of protective garment fabric is only carried out antibacterial processing on the lining surface in the prior art.
Lining of the present invention adopts ep-type material TPU conduct composite bed wherein; because the TPU material has good degradability; incinerate the no air pollution of burning; the protective garment fabric that wears after scrapping is embedded in the soil; be subjected to humidity and action of microorganisms; can degrade automatically, and protect the ecological environment of China effectively in 3 to 5 years.
In a word, lining of the present invention can stop infecting of virus (especially SARS virus) effectively, and the medical worker is worn on body and has unidirectional wet perspire again, and lining itself also has the effect of virus killing sterilization, also can reduce environmental pollution when protective clothing wears to scrap when handling, have the environmental protection characteristics.
(4) description of drawings: Fig. 1 is a partial perspective cutaway view of the present invention.
(5) specific embodiment: shown in Figure 1.The present invention's knitted cloth 1 that absorbs water is selected absorbent ventilate areolation preferably usually for use, outer shell fabric 2 selects for use the spring Asia of frivolous softness to spin the terylene waterproof and oilproof and through the lining of antistatic treatment usually, in the production process by special equipment and multiple processing technology, between overlapping continuous suction knitted cloth 1 and outer shell fabric 2, apply gummed and be connected with TPU moisture-permeable film 3, described suction knitted cloth 1 and outer shell fabric 2 compound pressed and overlapped are fused, constitute three layers of composite-like lining (shown in Figure 1).For increasing the bacteriostasis of protective garment fabric itself, described TPU moisture-permeable film 3 can adopt the nanometer-level silver series inorganic antibiosis material to constitute; Certainly, TPU moisture-permeable film 3 also can select for use the nano grade titanium series inorganic antibiosis material to constitute.Usually the thickness of TPU moisture-permeable film 3 is chosen between the 10-20 μ m, is preferably in 15 μ m.The protective clothing that lining of the present invention is made, its thoroughly wet perspire mechanism: the medical worker is worn on after one's death, TPU moisture-permeable film in the composite material contains very easily the hydrophilic radical with water molecules, the wet gas hydrone that produces when human body is perspired, be adsorbed on suction knitted cloth 1 inner surface of human body skin, and inner surface (shown in Figure 1) in TPU moisture-permeable film 3 is conducted in moisture absorption by suction knitted cloth 1, increase along with the molecular weight water of TPU moisture-permeable film inner surface absorption, the wet gas hydrone that produces in the sweat had been from high-temperature aspect TPU moisture-permeable film 3 inner surfaces of human body skin (both near), to low temperature aspect (outer surface of the TPU moisture-permeable film 3 that is connected with outer shell fabric 2 that directly contact with ambient temperature) spread conduct be expelled to external.
