Lub tshuab tsis pom: Vim li cas koj cov khaub ncaws tuaj yeem tiv nag?
Thaum taug kev ntawm txoj kev hauv nag, peb feem ntau tso siab rau lub tsho lossis lub tsho tiv thaiv cua uas tuaj yeem "tshem dej," tab sis tsis tshua xav txog cov ntsiab cai ntawm kev tshawb fawb tom qab lawv. Cov dej tsis muaj dej thiab dej -wicking zog ntawm textiles tsis cia siab rau ib co txheej los yog ib tug tshwj xeeb fiber, tab sis yog ib tug complex system uas integrates cov ntaub ntawv science, dej mechanics, thiab nto physics.
Kev ua haujlwm tsis zoo ntawm cov ntaub ntawv tseem ceeb yog hais txog nws lub peev xwm los tiv thaiv cov dej ntawm ib sab mus rau lwm qhov. Qhov kev ua tau zoo no feem ntau yog txiav txim siab los ntawm peb yam: lub wettability ntawm fiber ntau, txheej txheej ntawm cov ntaub, thiab kev cuam tshuam ntawm ib puag ncig uas nws siv.
Lub wettability ntawm fiber ntau yog qhov tseem ceeb rau kev txiav txim siab seb cov ntaub yog "hydrophilic" lossis "hydrophobic." Thaum cov dej poob rau ntawm qhov chaw fiber ntau, yog tias lub kaum sab xis ntawm qhov sib cuag tsawg dua 90 degrees, cov fiber ntau tau yooj yim wetted, thiab cov ntaub zoo li cov dej wick. Piv txwv li, yog tias lub kaum sab xis yog siab dua 90 degrees, cov fiber ntau muaj cov khoom tsis muaj dej. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias txawm tias cov fiber ntau nws tus kheej tsis muaj dej, yog tias cov qauv ntaub yog xoob thiab lub qhov hws loj, dej tseem tuaj yeem nkag mus los ntawm kev ua haujlwm capillary. Yog li ntawd, cov khoom siv dej tsis zoo tiag tiag feem ntau muab cov fiber ntau hydrophobicity nrog cov qauv nruj nruj.
Txheej yog ib txoj hauv kev los txhim kho cov dej tsis zoo ntawm cov ntaub. Los ntawm kev npog cov ntaub npog tas li, dej - zaj duab xis tsis sib haum, dej nkag tuaj yeem thaiv tau zoo. Cov txheej thaum ntxov, thaum tsis muaj dej tsis zoo, feem ntau ua rau muaj kev ua pa, ua rau muaj qhov hnyav thaum hnav. Niaj hnub no, cov thev naus laus zis ntau dua siv cov txheej txheem microporous waterproof uas tswj cov dej tsis zoo thaum tso dej kom dhau, thiab tau siv dav hauv cov khaub ncaws sab nraum zoov.
Environmental Factors kuj tseem ceeb heev. Kev hloov pauv ntawm cov av thiab qhov kub thiab txias tshwj xeeb cuam tshuam rau cov dej -wicking zog ntawm hydrophilic fabrics. Nyob rau hauv qhov chaw siab -cov av noo, fibers nqus dej noo thiab o, txhim kho capillary kev txiav txim thiab yog li ua rau cov ntaub ntawv dej ntau ntxiv -wicking zog. Cov ntaub tsis muaj dej, txawm li cas los xij, tsis tshua cuam tshuam los ntawm ib puag ncig ib puag ncig vim tias lawv cov fibers nqus yuav luag tsis muaj dej noo. Qhov no piav qhia tias yog vim li cas tib lub tsoos tsho yuav nthuav tawm cov dej tsis sib txawv hauv cov huab cua sib txawv.
Cov dej tsis muaj dej thiab dej-wicking thev naus laus zis ntawm textiles tsis yog tsuas yog los ntawm cov khoom siv engineering tab sis kuj yog ib qho lus teb zoo los ntawm tib neeg mus rau ib puag ncig ntuj. Los ntawm raincoats mus rau sweatshirts, los ntawm kev kho mob textiles mus rau ua liaj ua teb npog cov ntaub ntawv, qhov no seemingly me ntsis kev ua tau zoo qhia profoundly cuam tshuam cov khoom functionality thiab peb kev. Lwm zaus koj hnav lub tsho "dej-repellent", tej zaum koj yuav nco ntsoov tias nws muaj kev sib koom tes ntawm kev tshawb fawb thiab thev naus laus zis.
