The specific embodiment
Durability composite and flexible material of the present invention comprises three-decker, is respectively outer, intermediate layer and nexine.Its ectomesoderm adopts knitting, woven cotton or chemical ﹠ blended fabric, through functional treatment, makes and wherein contains water repellent, antistatic additive and fire retardant.The wet thoroughly functional membrane of environmental protection is adopted in the intermediate layer, as polyurethane polyethers film, polyurethane film, polyethylene film, polypropylene screen, pore type polyurethane film and pore type poly tetrafluoroethylene etc.Nexine adopts woven or knitting single face top-weight fabric that material chitin fiber with bacteria resistance function makes with fiber blends such as far infrared, cotton, spun silk, soybean respectively, mesh fabric etc.Above-mentioned compound with wet thoroughly functional membrane of intermediate layer environmental protection and nexine fabric respectively through the outer fabric behind the functional treatment, can obtain durability composite and flexible material of the present invention.
Nexine adopts the blend fabric of chitin fiber and other fiber, and chitin fiber is a kind of natural polymer, and is nonpoisonous and tasteless, good biologically active, biocompatibility and degradability are arranged, being used for weaving face fabric has well antibacterially, and moisture absorption is ventilative, the effect of deodorization.Far IR fibre is a terylene, and polypropylene fibre, acrylic fibers are carrier, and its wavelength is 8~14 μ m, and radiance is (generally to be considered as radiation effects more than 65%) more than 80%, and it can promote microcirculation, strengthens health.Fibre and soya and spun silk have soft smooth, the good action that moisture absorption is wet thoroughly.
The film that adopt in the intermediate layer is the wet thoroughly functional membrane of environmental protection, as polyurethane polyethers film, polyurethane film, pore type polyurethane film, this polymer is made by the material that has " firmly " segment and " flexibility " segment on the strand, because the intersegmental architectural difference that exists of these chains, produce the thermodynamics intolerance betwixt, form broken face between the interface, present semipermeability in these fine fisssures from point, the relative humidity difference between skin surface and the air can be brought out this semi-permeable phenomenon.Also have hydrophilic radical on this polymer macromolecule simultaneously, also can with sweat gas that human body produced by hydrophilic radical be sent to the external world through absorption-diffusion-desorb, thereby have the wet thoroughly function of high-effective water-proof blocking solution.
Outer fabric has and wets through functional treatment, and is saturating wet, fire-retardant, antistatic, waterproof, the effect of anti-virus.
Compound by trilaminate material, that the composite and flexible material that obtains has is wet, the function of blocking solution, fire-retardant, antistatic, waterproof, anti-virus, and has good durability.Reached the medical protective garment specification requirement and the industry standard (GB19082-2003) of up-to-date promulgation, and general protective garment standard (GB/T13661-1992).After testing, the technical indicator of composite and flexible material of the present invention is: thickness 50 μ m~120 μ m, grammes per square metre is 130~250g/m
2, hydrostatic pressing>1000mmH
2O, vapor transfer rate>2500g/m
224h, rejection rate 〉=99%, fire resistance B2 level (among the GB/T.5455), antistatic behaviour: carried charge<0.6 μ c.The product washing can be adopted compound washing powder, and medicated soap or soap wash more than 30 times through 40 ℃ soap or compound washing powder, and its protection ratio still reaches more than 98%.Antibacterial test is carried out according to ministry of Health of China " disinfection technology standard " third edition in 1999, and test result is staphylococcus aureus bacteriostasis rate>76%, Friedlander bacteriostasis rate>75%.And Ministry of Public Health's standard to be difference>26% of test group and negative control group promptly regard as antibiotic effectively.
Compare prior art, composite and flexible material of the present invention can effectively be prevented infiltrations such as sealing, dirt, blood, virus, the spittle and body fluid making steam can oppositely pass through this composite and flexible material, thereby make it have poisture-penetrability again.By adding fire-retardant and antistatic additive, this composite and flexible material has had fire-retardant and anlistatig performance simultaneously.Owing to adopt three-layer composite structure, and the composite and flexible material is knitting, woven cotton or chemical ﹠ blended fabric, and the nexine fabric contains chitin fiber, and is so composite and flexible material of the present invention also has good durability, comfortable and easy to wear with its clothes of making.Composite and flexible material of the present invention can be used to make medical protective garment, cap, and gloves, mouth mask, oversleeve, products such as shoe cover, these products can be used for hospital, infectious diseases such as hospital for infectious diseases control zone.
The manufacture process of durability composite and flexible material of the present invention is: at first knitting, woven cotton or chemical ﹠ blended fabric are carried out functional treatment, add fire retardant, antistatic additive, water repellent.Wherein fire retardant FR 1, is the nitrogen phosphorus type flame retardant; Produce by beautiful Dehua, Shanghai worker Co., Ltd.Antistatic additive YZ-1 is the nonionic polymerizable compound; Produce by Shanghai Ling Zhao development in science and technology Co., Ltd.Water repellent AG-480 is for Organic fluoride is a waterproofing agent; Become chemical industry Co., Ltd. to produce by last hamming.The concentration of various auxiliary agents is fire retardant 80~120g/l, antistatic additive 30~60g/l, and water repellent 40~60g/l, the use of various auxiliary agents is adopted with bathing (single bath process) and is padded.Make the above-mentioned fabric and the environmental protection hydrophilic functional membrane in intermediate layer compound then through arrangement, environmental protection hydrophilic functional membrane can be polyurethane polyethers film, polyurethane film, polyethylene film, polypropylene screen, pore type polyurethane film etc., thickness is 15~25 μ m, complex method can adopt methods such as point-like, netted, gluing, flame, and adhesive is polyurethane or acrylate.Then that above-mentioned compound good material is compound with the nexine material again, recombination process is the same.
