Lub luag haujlwm tseem ceeb ntawm cov ntaub ntawv tsis muaj dej tsis zoo yog: tsis muaj dej, noo noo permeable, breathable, insulating, windproof thiab sov.Nyob rau hauv cov nqe lus ntawm ntau lawm technology, cov kev cai ntawm waterproof breathable ntaub yog ntau dua li ntawm cov ntaub ntawv zoo tib yam waterproof.Nyob rau tib lub sijhawm, los ntawm qhov zoo ntawm qhov pom, cov ntaub ntawv tsis muaj dej tsis muaj dej kuj tseem muaj lwm cov ntaub ntawv tsis muaj dej tsis muaj cov yam ntxwv ua haujlwm.Waterproof breathable npuag tsis tsuas yog txhim kho huab cua nruj thiab dej nruj ntawm cov ntaub, tab sis kuj muaj nws qhov tshwj xeeb chav permeability, uas tuaj yeem ua rau cov dej vapor hauv cov qauv tawm sai sai, zam cov pwm los ntawm cov qauv, thiab ua rau tib neeg lub cev qhuav. txhua lub sijhawm.Nws zoo kawg nkaus daws cov teeb meem ntawm huab cua permeability, tiv thaiv cua, tsis muaj dej, thiab txuag hluav taws xob, thiab lwm yam, thiab yog hom tshiab ntawm kev noj qab haus huv thiab kev tiv thaiv ib puag ncig.
Nyob rau hauv lub xeev ntawm dej vapor, cov dej hais me me heev.Raws li lub hauv paus ntsiab lus ntawm capillary zog, lawv muaj peev xwm infiltrate lub capillary mus rau lwm sab smoothly, thiab yog li muaj chav permeability.Thaum cov dej vapor condenses rau hauv cov tee dej, cov khoom ua loj dua.Vim yog cov nyhuv ntawm qhov nro ntawm cov dej tee dej (dej molecules "rub tawm ib leeg"), cov dej molecules tsis tuaj yeem khiav tawm ntawm cov tee dej kom nkag mus rau sab nraud, uas yog los tiv thaiv dej infiltration thiab ua rau cov dej permeable film waterproof.
Cov ntaub ntawv tsis muaj dej muaj tseeb tuaj yeem tiv taus qhov dej siab thiab tsis pom dej hauv qhov chaw ntub dej rau lub sijhawm ntev.Piv txwv li, yog tias koj taug kev hauv nag ntev ntev, txhos caug lossis zaum ntawm qhov chaw ntub dej, yuav tsis muaj dej ntws.
Tus phooj ywg uas hu rau sab nraum zoov ib lub sij hawm yeej paub, lub high-tech uas sab nraum zoov khaub ncaws flaunts, kev ua tau zoo heev muaj feem xyuam rau cov waterproof breathable fabrics, yog li waterproof breathable fabrics tom qab tag nrho yuav ua li cas lub hauv paus ntsiab lus, tag nrho cov hom ntawm cov ntaub ntawv ntawm lub ua lag luam li cas tom qab tag nrho cov nyhuv?
Waterproof, breathable, suab nws tus kheej yog ib tug khub ntawm contradictory lub cev, txij li thaum tsis muaj dej, yog li raug kaw, peb txhua tus paub, dej yog impervious rau tag nrho cov, yog li yuav ua li cas ua pa?Qhov tseeb qhov no thiab dej nta, raws li txhua leej txhua tus paub, qhov saum npoo ntawm cov dej muaj qhov nro, tuaj yeem pom hauv koj lub neej, thaum peb nchuav dej me ntsis siab dua li cov dej nyhav kuj yuav tsis ntws, qhov no yog qhov tshwm sim ntawm dej nto nro, qhov tshwm sim no feem ntau yog vim dej molecule muaj qhov loj dua molecular attraction, tsuas yog ua rau txhua tus dej molecule kom ze li sai tau thiab tsis sib cais, thiab dej vapor kuj yog dej molecules, tab sis lub sij hawm no ntawm txhua molecule yog ywj siab, yog li ntawd nws tsis tuaj yeem sib txuas ua ke.Siv cov cuab yeej no, kev sim kuaj pom tau tias yog lub qhov me me txaus, nws tuaj yeem dhau tsuas yog dej hauv lub xeev vapor, tsis yog kua dej.Siv cov yam ntxwv no thiaj li tsim cov khoom siv tsis muaj dej tsis zoo, yog kev siv cov khoom siv polyester fiber ntau staggered daim ntawv ntau lub qhov me me hauv cov ntaub, nrog rau cov khoom siv dej tsis zoo tshaj plaws GORE - TEX, piv txwv li, cov ntsiab lus ntawm cov khoom tsis yog square inch. mus rau ntau pua lab tus me me tawg, txhua lub qhov taub yog ib tshaj nees nkaum txhiab ntawm cov kua dej tsawg kawg nkaus, tab sis 700 lub sij hawm loj dua qhov tsawg kawg nkaus dej vapor xeev, qhov no yog lub hauv paus ntsiab lus ntawm cov dej tsis zoo thiab ua pa.
