Txhawm rau tiv thaiv cov huab cua hloov pauv thaum mus ncig sab nraum zoov, lub tsho tsis muaj dej tsis muaj dej, cov ris tsho thiab txawm tias khau tseem ceeb heev, tab sis kuv ntseeg tias ntau tus neeg tsis paub meej txog cov ntsiab lus ntawm cov ntaub tsis muaj dej tsis zoo thiab cov ntaub tsis muaj dej tsis zoo. Tau ntsib nrog ntau tus neeg thov tias lawv cov khoom tsis muaj dej tsis zoo Thaum nws los txog rau cov khoom siv sab nraum zoov, yuav muaj qee qhov tsis ntseeg. Cov ntaub twg yog cov dej tsis zoo tiag tiag? Vim li cas cov khoom uas twb tau siv cov ntaub tsis muaj dej yuav tsum tau kho nrog cov tshuaj tiv thaiv dej? Cia kuv qhia koj luv luv txog qhov sib txawv.

Waterproofing ntawm fabrics feem ntau txhais tau hais tias cov ntaub nws tus kheej muaj nuj nqi ntawm waterproofing. Tom qab cov ntaub ntawv tsis muaj dej tsis zoo tau ntsib cov ntaub ntawv cog lus thawj zaug thiab cov ntaub ntawv tsis muaj dej tsis zoo, lawv tam sim no tsuas yog pasted zaj duab xis hom ntaub. ua hauj lwm zaj duab xis.

Cov ntaub nplaum zaj duab xis uas pib ua lag luam loj tshaj plaws yog PTFE (polytetrafluoroethylene) films, uas yog microporous films. Cov dej tsis zoo yog qhia los ntawm cov dej siab tus nqi nws tuaj yeem tiv taus, tsis yog 100. feem pua ​​dej tsis zoo, thiab raws li European ib puag ncig kev tshawb fawb, PTFE cov ntaub ntawv tsim cov khoom tsis zoo ib puag ncig thaum tsim khoom, landfilled thiab incinerated. Nyob rau hauv xyoo tas los no, lub zej zog tiv thaiv ib puag ncig tau nug cov ntaub ntawv PTFE, thiab qee lub tebchaws tau pib txwv tsis pub siv PTFE cov ntaub ntawv. Kev muab pov tseg thiab kev ua kom tsis muaj teeb meem yog qhov tseem ceeb hauv kev pov tseg pov tseg hauv ntiaj teb, thiab ob txoj kev pov tseg no yuav tsim cov tshuaj perfluorinated thaum cuam tshuam nrog PTFE cov ntaub ntawv. Fluoride yuav ua phem rau cov huab cua thiab av. Vim lub sij hawm ntev ntawm ntuj decomposition ntawm fluoride, ib puag ncig muaj kuab paug los ntawm PTFE khoom yuav kav ntev thiab ntev. Hauv kev sib piv, lwm hom zaj duab xis uas tau siv los ntawm ntau thiab ntau lub npe nyob rau hauv xyoo tas los no-tsis yog-porous hydrophilic zaj duab xis tsis yog tsuas yog tsis ntxeem tau thiab 100 feem pua ​​waterproof, ua rau cov dej tsis zoo ntawm cov khoom txhim khu kev qha, thiab qee qhov tsis- porous hydrophilic films muaj kev ntseeg siab dua. Vim tias nws qhov kev tiv thaiv ib puag ncig thiab tsis muaj kev phom sij rau tib neeg lub cev, nws tau nyiam los ntawm ntau tus neeg hauv kev lag luam, xws li Sympatex zaj duab xis, uas yog cov khoom siv molecular ntawm polyether thiab polyester, tsis muaj PTFE (polytetrafluoroethylene) cov khoom, thiab tuaj yeem tiv tauj ncaj qha. daim tawv nqaij, tsis muaj teeb meem rau lub cev, thiab tuaj yeem siv tau zoo li lub raj mis PET.

Feem ntau, cov tuam txhab tsim cov ntaub nrog cov cuab yeej ua yeeb yaj kiab tsis ncaj qha muag cov yeeb yaj kiab rau cov khaub ncaws hom. Lawv muab cov yeeb yaj kiab nrog lwm cov ntaub ntawv los ntawm cov txheej txheem pasting los tsim cov ntaub ntawv sib xyaw (raws li qhia hauv daim duab saum toj no, cov txheej txheem nruab nrab yog ib zaj duab xis), thiab cov khoom lag luam tsuas yog yuav tsum tau yuav cov ntaub ntawv sib xyaw no los ua cov khoom lag luam tsis muaj dej ncaj qha. Cov ntaub no siv rau kev sib xyaw nrog cov yeeb yaj kiab tsis yog dej tsis zoo rau lawv tus kheej, xws li polyester fiber, nylon, thiab lwm yam, yog li thaum peb hnav cov khaub ncaws tsis muaj dej thiab ntsib huab cua ntub, peb yuav pom cov dej nkag mus rau hauv cov khaub ncaws, ib yam li cov khaub ncaws ua los ntawm cov ntaub zoo tib yam. , tab sis lub puab txheej ntawm lub tsoos tsho yog qhuav, thiab tsis muaj dej seeps nyob rau hauv, uas yog lub luag hauj lwm ntawm cov waterproof zaj duab xis nyob rau hauv nruab nrab ntawm lub composite ntaub.

Qhov peb pom yog tias cov dej tau tawg mus rau hauv cov dej me me ntawm cov khaub ncaws thiab tom qab ntawd plam tawm (raws li qhia hauv daim duab saum toj no), feem ntau vim tias cov ntaub siv tau raug kho nrog dej tawm. Kev kho dej tiv thaiv kab mob yog qhov tshwj xeeb txheej npog ntawm cov ntaub. Kev kho mob, feem ntau yog ntxiv DWR (Durable WaterRepellency) thaum cov ntaub tiav tiav, thiaj li tau txais cov dej tiv thaiv tau ntev. Lub hom phiaj ntawm kev siv DWR txheej yog tias thaum dej ntws mus rau saum npoo ntawm lub tsoos tsho, nws tuaj yeem tsim cov tee dej me me los yog xaub ncaj qha los ntawm cov tsoos tsho los tiv thaiv cov ntaub los ntawm kev nqus dej, thiab tib lub sijhawm, nws kuj ua rau nws yooj yim dua kom tshem tawm cov roj stains txuas rau saum npoo ntawm cov tsoos tsho. Feem ntau cov khaub ncaws tsis muaj dej tau txais kev kho DWR dej-repellent no, thiab qhov zoo ntawm kev siv DWR kev kho yog qhov txheej txheej ntawm cov khaub ncaws tsis tuaj yeem nqus dej, yog li txhawm rau xyuas kom meej tias cov ntaub tsis muaj dej tsis zoo tuaj yeem ua tau zoo ua pa, kom tib neeg lub cev muaj zog. hnav zoo heev. xav.

DWR thev naus laus zis tuaj yeem faib ua ob hom ntawm cov khoom muaj feem xyuam: fluoride-muaj DWR thiab fluoride-dawb DWR. Fluoride-muaj DWR yog hais txog kev kho saum npoo ntawm DWR raws li fluoropolymers, xws li PFOA (perfluorooctanoate), uas yog siv dav hauv kev lag luam khaub ncaws. Cov ntsiab lus quasi muaj qhov teeb meem tsis yooj yim degraded, thiab tuaj yeem tso tawm rau hauv dej thiab cua los ntawm ntau yam xws li cua sov, dej immersion, thiab ultraviolet rays, ua rau muaj kev puas tsuaj rau tib neeg thiab lwm yam tsiaj thiab nroj tsuag. Cov kws tshawb fawb twb tau kuaj pom muaj qhov sib xyaw no hauv tib neeg thiab tsiaj cov ntshav kuaj thoob ntiaj teb. Txawm hais tias tam sim no tsis muaj lub hauv paus rau kev taw qhia txog kev pheej hmoo carcinogenic ntawm PFOA thiab cov kev cai cuam tshuam rau kev txwv ntawm PFOA, German Federal Environment Agency (UBA) tau thov kom suav nrog PFOA hauv cov npe tshuaj uas xav tias muaj tshuaj lom rau cov menyuam yaus. qhov system.

Tam sim no, DWRs tsis muaj fluorocarbons muaj ntau: siv quav ciab, paraffin, polyurethane, dendrimers lossis siloxanes, thiab lwm yam los hloov cov fluorocarbons ua cov ntsiab lus tseem ceeb xws li cov tshuaj tua dej rov qab rau cov khoom sab nraum zoov. Vim li cas SympaTex? Txij li thaum nruab nrab -2008, nws tau pib muab cov neeg siv khoom nrog ib puag ncig tus phooj ywg, tsis muaj fluorocarbon-dawb DWR cov khoom siv tshuaj tua dej. Cov khoom no yog cov khoom lag luam zoo ib puag ncig rau textiles tsim ua ke nrog tus khub Rudolf Chemie: BIONICFINISHECO?. Qhov tseeb, SympaTex? tseem yog thawj lub tuam txhab tsim cov khoom tsis-fluorocarbon-raws li DWR dej-repellent technology khoom rau textiles.

Hauv Teb Chaws Asmeskas EPA 2010/2015 PFOA cov txheej txheem kev tswj hwm, cov tuam txhab tshuaj loj, suav nrog DuPont, Clariant, kuj tau yeem cog lus kom tshem tawm PFOA tshuaj lom hauv kev tsim tawm los ntawm 2015, thiab siv cov khoom lag luam zoo ib puag ncig thiab qis qis dua.

Nws yog ib qho tsim nyog hais tias DWR cov tshuaj tiv thaiv dej tsis tu ncua, tab sis txoj kev ntxuav kom raug thiab cov txheej txheem ironing tuaj yeem ua rau cov nyhuv ntawm DWR cov tshuaj tiv thaiv dej, thiab yog tias koj cov khaub ncaws poob cov tshuaj tiv thaiv dej, tsis txhob txhawj, tam sim no DWR txheej rov ua dua tshiab muaj muag.

Yog li koj tuaj yeem pom tias cov khaub ncaws uas siv cov ntaub ntawv tsis muaj dej tsis zoo tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm 100 feem pua ​​​​cov dej tsis muaj dej (PTFE cov khoom lag luam nyob rau hauv qee qhov xwm txheej, cov yeeb yaj kiab tsis muaj dej tsis zoo hauv txhua qhov xwm txheej), tab sis txhawm rau kom tau txais kev hnav zoo dua, yog li tias cov ntaub ntawv tsis muaj dej tsis zoo no muaj cov nyhuv ua pa zoo, thiab DWR cov tshuaj tiv thaiv dej kuj tseem tsim nyog.

Tsis tas li ntawd, qhov ua tiav cov dej tsis zoo ntawm cov khaub ncaws muaj ntau yam ua rau kev ua haujlwm tsis zoo ntawm cov kua nplaum thiab cov zippers siv ntawm cov seams, vim hais tias cov dej tsis zoo thiab dej tawm ntawm cov ntaub xa mus rau kev ua haujlwm ntawm cov ntaub nws tus kheej, cov koob qhov ntawm cov ntaub. cov seams los yog qhov khoob ntawm lub zipper. Nws tsis tuaj yeem ua tiav 100 feem pua ​​​​ntawm cov dej tsis muaj kev kho cov tsoos tsho.
