medical grade anti is 一 广义 concept, medical ring lower 医护人员穿戴 各 type clothing/apparel, day as 服, outer 科手术服, 隔离衣以 and anti and other. according to application ring and function different, medical grade anti for/regarding liquid and fine 菌渗入 has different standards and other grade, using/adopting material 也各不 same. 不, according to basic function large can separation is heavy use type and use type (one-time property)两 type.

heavy use type anti 护服, generally as is 医护人员 day as and 手术服 and other. main/primary using/adopting machine 织布, high material, coating material and lamination material and other material made formed. due to lamination material is will 普通织 material and 一层特殊 film through lamination process composite/compounding in made, anti property can and wet property can relatively good formed is inner selection.

comparison high lamination material is PTFE ultra- grade anti water wet composite/compounding material. material is PTFE is raw materials, 经 膨化 tensile rear formed types tool has micro property film, will film use process combined in various material and upper, formed is new type material. due to film small, distribution uniform, rate large, in maintain gas meanwhile, can 滤包括 fine in inner pellets, to 净化且通风 目. this type of lamination material can anti 风, anti water, gas, wet, but also property good. currently, 发达国家 large more use PTFE 材质. using/adopting PTFE composite/compounding film as is 隔离层研 made medical grade more function anti 护服, tool has resistant anti water, water, antimicrobial, anti-static, flame retardant, wet and other material mechanical properties, for liquid, 病毒(liquid heavy or gas heavy) in conditions and pressure conditions lower tool has very good retardant property can, retardant 隔(滤) efficiency large 于99%.

延 long 石油延安 can chemical industry has responsibility company polypropylene (PP) plant/unit 转产无纺布 specialized material product, provide medical grade anti Raw Materials. (李庆琛 摄)

理想 medical grade anti 护服应该 tool has more function property, need can 保护医护人员免受 has has liquid 体, gas or tool property and micro material 侵袭, also need 穿 舒适, in tool retardant property can meanwhile, also need tool gas property, antimicrobial property and anti property, 不 危害人体健康. remove outer, anti 护服面 material selection also need cost and waste rear environmental protection issues.

can heavy use anti 护服, use rear need 进行洗涤 and 消毒, as 不方便, large large made it structure, but also use time rear, its anti property can has decline. 鉴于此, upper using/adopting one-time property non 织造(无纺布)材 material made formed anti 护服. this type of anti 护服, 经 进一步 antimicrobial, anti-static and other 处理, and property can 跟传统 textile product comparison 接近, but also price relatively low. therefore, in medical field/area 隔离衣 and anti in application relatively is 广泛.

currently, inner used for 无纺布 production large fiber separation is polypropylene (PP), polyester and viscous fiber. its in polypropylene (PP) ratio/proportion most high, 占62%. generally 而言, used for production 无纺布 polypropylene (PP) main/primary is high MFI polypropylene (PP) fiber material, in recent years, polypropylene (PP) high fiber material demand more heavy good factors effect/influence, by market good, production enterprise in R&D polypropylene (PP) fiber market. data statistics, 2019 year inner polypropylene (PP) fiber material output/production volume 约170 10,000 tons left right, year-on-year 2018 year growth 7.5%. its in high MFI polypropylene (PP) fiber material 95 10,000 tons, year-on-year growth 15.8%; in MFI polypropylene (PP) fiber material 77 10,000 tons, versus ratio basic unchanged.

无纺布 production process main/primary has viscous method, water method, method, SMS composite/compounding material and other. viscous method 无纺布 main/primary utilizing 化纤纺 filament methods formed polypropylene (PP) long filament, again gas or machine methods separation filament formed 网, its in and property can very 接近于传统 textile product; water method 无纺布, is through high pressure water high speed water for 涤纶, 锦纶, and other fiber 纤网喷射, make in fiber 运动而 heavy new and versus 互结, to solid formed day;闪蒸 method 无纺布, polyolefin is main/primary raw materials, using/adopting electrical separation filament, make filament strip/profile in tensile process in versus scratch formed electrical separation filament, versus 互排斥 maintain mono fiber 状态, rear electrical plant/unit make fiber poly formed 网, again hot formed;SMS composite/compounding 无纺布, is will types above property can non 织造纤网 through chemical, hot or machine and other methods composite/compounding in 一起, or is combined different formed process manufacturing 无纺布.

currently, one-time property anti more using/adopting polyethylene (PE) gas film made formed composite/compounding 无纺布. polyethylene (PE) gas film in LDPE/LLDPE resin in, add 50% left right specialty carbon acid 钙进行 blending, extrusion formed film rear toward tensile 一定倍 rate formed. due to polyethylene (PE) resin is thermoplastic property property material, can in conditions lower tensile and crystallization, tensile polymer and carbon acid pellets between interface 剥离, carbon acid pellets 周围就形 formed versus 互连通 蜿蜒曲折 孔隙 or 通道, positive is this and 通道赋予 film gas (wet) function, from 而沟通 film ring 境.

not only medical grade anti 护服 材 material need using/adopting chemical specialized material, but also clothing/apparel 接缝处也 need use 专业 胶 strip/profile 进行处理, this can has anti 止病毒 and other from 接缝位置穿透, to 医护人员专业 anti standards requirements. generally 讲, one-time property anti has 接缝均 use 无纺布 hot melt adhesive through ultra- 声波 bonding, make anti performance is 无缝无针孔, reinforcement anti 护服接缝 resistant force, 彻底杜绝接缝处漏 gas, water, 漏菌, 且穿 舒适.

近期, full medical grade anti demand amount increase, as is medical grade anti upper important material 之一 密封 strip/profile, demand amount large increase. 据韶关市 high plastics products has company general manager 张进波 introduction, 他们现 has output/production volume is day 120万米, can supply made as 15万 sleeve/set anti 护服 需 密封 strip/profile. its understanding to 情况 说, currently full large separation medical grade anti 护服 密封 strip/profile is enterprise production. new type 冠状病毒感染 肺炎疫情发生以, full medical grade anti demand amount increase. as is medical grade anti upper important material 之一 密封 strip/profile, demand amount meanwhile large increase, company full 体员工都 in full force 以赴, 支援湖北省 medical grade anti enterprise production, 保障疫情 front 线人员 material 资 需.

in recent years, USA, Europe, Japan and other 发达国家 and for one-time property medical grade product use amount 一直呈现稳步 growth 态势, for/regarding material made and application as relatively more formed 果. its in, DuPont company development strong/high material, is method 无纺布 代 table/sheet property product, in medical anti field/area outlook/prospects separation good.

DuPont company TYVEK特卫 strong/high material, high density polyethylene (PE) 经闪蒸 process made formed non fine fiber, its from 0.5 to 10 micron and other. using/adopting add hot add pressure combined, combined agent /无 direction property long filament structure, tool has high material strong/high degree and chemical resistant stability property, ultra- fine fiber formed structure. strong/high tough long filament fiber ensure material strong/high degree, resistant property and low 尘屑, can make various gas high 效透, but also tool has excellent micro material retardant property, material tool has material versus property. testing, strong/high material soft/flexible, light 便, gas property good, wet amount 7154克/平方米, surface resistant wet property to 4 grade.
