Nyob rau hauv lub ntiaj teb no ntawm cov khaub ncaws sab nraum zoov, "waterproof" yog ib qho ntawm feem ntau siv -thiab feem ntau tsis to taub- cov nqe lus. Rau cov neeg yuav khoom tsim cov tsho kev cai, khaub ncaws los nag, lossis cov khaub ncaws sab nrauv, kev nkag siab txog kev tiv thaiv dej tsis zoo yog qhov tseem ceeb rau kev txiav txim siab paub. Ob lub thev naus laus zis tsim lub hauv paus ntawm cov khaub ncaws tsis zoo niaj hnub no:DWR (Durable Water Repellent)thiablamination. Thaum lawv feem ntau hais ua ke, lawv ua haujlwm sib txawv kiag li.
Xav txog nws li no: lamination yog qhovdaim ntaub thaivuas txwv tsis pub dej nkag mus rau hauv cov ntaub, thaum DWR yog qhovthawj kab ntawm kev tiv thaivuas tiv thaiv cov ntaub thaiv npog los ntawm kev ntxhov siab. Ob leeg yog tsim nyog. Tsis yog ib leeg txaus. Hauv qab no, peb rhuav tshem txhua qhov kev siv tshuab ua haujlwm li cas, lawv ua haujlwm li cas rau ib leeg, thiab koj cov neeg yuav khoom yuav tsum paub dab tsi thaum ntsuas koj cov khoom lag luam.
Ntu 1: Lamination - Cov Membrane Waterproof
Lamination yog dab tsi?
Lamination yog hais txog cov txheej txheem ntawm kev sib txuas cov dej tsis sib haum, ua pa tawm mus rau lub ntsej muag ntaub (thiab feem ntau yog cov ntaub npog). Qhov no tsim cov txheej txheem ntau- txheej txheej uas txwv cov dej ua kua los ntawm kev hla thaum tso dej vapor (hws) kom dim. Lamination yog dab tsi ua rau khaub ncawskev tsim qauvwaterproof.
Hom Hom Laminates
| Hom | Kev tsim kho | Zoo tshaj rau |
|---|---|---|
| 2- Txheej | Lub ntsej muag ntaub + daim nyias nyias (backer yog cais mesh lossis liner) | Cov khaub ncaws hnav khaub ncaws hnav, nkag mus- qib plhaub |
| 2.5- Txheej | Lub ntsej muag ntaub + daim nyias nyias + txheej txheej tiv thaiv | Lub teeb yuag, ntim tau los nag tsho |
| 3- Txheej | Lub ntsej muag ntaub + daim nyias nyias + cov ntaub qhwv rov qab | High -kev ua tau zoo outerwear, kev siv |
Cov Metrics Tseem Ceeb Cov neeg yuav khoom yuav tsum nkag siab
Waterproof Rating ( ntsuas hauv mm):
Tus lej no qhia tias dej siab npaum li cas cov ntaub tuaj yeem tiv taus ua ntej xau. Kev ntsuam xyuas lub taub hau hydrostatic yog siv los txiav txim qhov no.
5,000-10,000 hli:Lub teeb rau nruab nrab los nag; haum rau siv xws li
10,000-15,000 hli:Nruab nrab los nag hnyav; haum rau hiking, commuting
15,000-20,000 hli:Los nag thiab daus; haum rau skiing, mountaineering
20, 000+ hli:Cov mob hnyav heev; professional- qib kev tiv thaiv
Kev ntsuas qhov ua pa ( ntsuas hauv g / m² / 24hr):
Qhov no ntsuas ntau npaum li cas vapor tuaj yeem dhau los ntawm cov ntaub hauv lub sijhawm 24-teev.
5,000 – 10,000 g:Tsim nyog rau kev ua haujlwm qis - siv zog
10,000 – 15,000 g:Zoo rau nruab nrab mus rau siab exertion
15,000+ g:Zoo heev rau kev ua haujlwm siab - xws li caij skiing, paddling, lossis alpine nce toj
Dab tsi los sib txuas lus rau cov neeg yuav khoom
*"Lamination txiav txim siab qhov kev ua tau zoo ntawm cov ris tsho hauv qab. Thaum peb qhia txog 20K / 15K npuag, peb qhia koj tias lub tsho no tuaj yeem tiv taus los nag hnyav thaum tso tawm hws los ntawm qhov siab - kev tawm dag zog kom dim. Lamination yog ib qho khoom ruaj khov- nws yuav tsis ntxuav tawm lossis hnav nrog kev siv ib txwm. "*
Ntu 2: DWR - Kev Tiv Thaiv Dej Taub Hau Ua tiav
DWR yog dab tsi?
DWR yog cov tshuaj polymer txheej siv rau lub ntsej muag sab nrauv ntawm cov khaub ncaws tsis zoo. Nws tsis ua rau cov ntaub tsis muaj dej; es, nws ua rau dej hlaws thiab dov tawm ntawm qhov chaw. Qhov no ua haujlwm rau ob txoj haujlwm tseem ceeb:
Nws tiv thaiv lub ntsej muag ntaub los ntawm kev saturated, uas yuav ntxiab cua sov thiab ua kom hnyav
Nws tuav lub breathability ntawm daim nyias nyias los ntawm kev tiv thaiv "wetting tawm"
Yuav ua li cas DWR ua haujlwm
Thaum DWR txheej yog tshiab thiab nquag, cov hlaws dej thiab dov tawm ntawm daim ntaub. Raws li DWR hnav los ntawm kev siv, kev puas tsuaj, thiab kev kis kab mob, lub ntsej muag ntaub pib "ntub tawm" - txhais tau tias dej nkag mus rau hauv txheej txheej. Thaum qhov no tshwm sim, daim nyias nyias tseem tuaj yeem khaws cov dej tawm, tab sis kev ua pa tsis zoo yog qhov cuam tshuam loj heev vim tias cov txheej txheem saturated txheej thaiv vapor los ntawm kev khiav tawm.
PFC-DWR Dawb: Kev Lag Luam Hloov
Kev kho DWR ib txwm muaj raws li cov tshuaj perfluorinated (PFCs), uas tau ua rau muaj kev txhawj xeeb txog ib puag ncig thiab kev noj qab haus huv. Kev lag luam tam sim no hloov mus rauPFC - dawb DWRformulations, feem ntau yog ua los ntawm hydrocarbon los yog silicone -raws li polymers. Txawm hais tias kev ua tau zoo tam sim no sib piv, PFC- kev kho mob dawb yuav xav tau kev rov ua dua tshiab dua.
DWR Kev Saib Xyuas: Cov neeg yuav khoom yuav tsum paub dab tsi
DWR tsis ruaj khov. Nws degrades nyob rau lub sij hawm thiab yuav tsum tau refreshed. Tham nrog koj cov neeg yuav khoom:
DWR tuaj yeem rov qab los siv cov txheej txheem ntxuav-hauv lossis tshuaj tsuag- ntawm kev kho mob
Kev ziab kom qhuav ntawm cov cua kub tsawg tuaj yeem rov ua qee yam DWR cov qauv
Kev siv cov tshuaj detergents lossis cov ntaub softeners yuav ua rau DWR tsis ua haujlwm
