Nyob rau hauv xyoo tas los no, tib neeg muaj kev xav tau ntau dua thiab siab dua rau kev nplij siab thiab kev ua haujlwm ntawm cov khaub ncaws fabrics.Nrog rau kev nce ntawm tib neeg lub sij hawm nyob rau hauv kev ua si sab nraum zoov, qhov kev sib nrig sib nkag mus thiab kev koom ua ke ntawm xws li hnav ris tsho thiab sportswear kuj nce siab nyiam los ntawm feem coob ntawm cov neeg siv khoom.Cov ntaub ntawm cov khaub ncaws zoo li no tsis tsuas yog xav tau kev nplij siab zoo xwb, tab sis kuj yuav tsum tau hais tias thaum koj ua haujlwm, ib zaug koj tawm hws, cov khaub ncaws yuav tsis muab tshuaj txhuam rau ntawm daim tawv nqaij thiab ua kom txias ntub, hnyav.Yog li, qhov xav tau tshiab ntawm kev nqus dej noo thiab ua pa tawm ua haujlwm tau muab tso rau pem hauv ntej.
Txawm li cas los xij, rau cov ntaub ntub dej nqus thiab tawm hws, cov neeg siv khoom yuav tsis meej pem.Qhov tseeb, qhov no yog ob lub tswv yim, uas yog cov ntaub ntub dej nqus thiab tshem tawm cov dej noo.
Ua ntej tshaj plaws, cia peb tham txog kev nqus dej noo: cov khoom siv hluavtaws siv polyester ua piv txwv, qhov tseeb, qhov nqus dej me me, tsis zoo noo noo permeability, yooj yim los tsim ib qho kev xav zoo thaum ua haujlwm;Natural fibers coj paj rwb ua piv txwv, nws qhov kev nqus dej noo yog qhov zoo thiab nyiam hnav, tab sis thaum tib neeg tawm hws me ntsis ntxiv, cov paj rwb fiber ntau yuav nthuav dav vim kev nqus dej noo, thiab lo rau ntawm daim tawv nqaij, tib lub sijhawm, dej. divergence tus nqi yog qeeb, yog li ua rau ib tug txias ntub zoo rau tib neeg lub cev.
Yog li ntawd, rau tag nrho cov ntaub, tshwj xeeb tshaj yog cov khoom polyester, kev kho mob nrog hydrophilic additives nyob rau hauv lub post-tiav theem yog ib txoj hauv kev zoo los txhim kho cov dej noo.
Tab sis yog qhov kawg ntawm nws?Puas yog cov tshuaj rau kev nqus dej kom tus neeg hnav qhuav?Hygroscopic = perspiration?
Tau kawg tsis!Tsuas yog thaum cov dej noo absorbed hauv cov ntaub yog tawm mus rau saum npoo ntawm cov ntaub kom deb li deb tau, cov dej noo yog tag nrho evaporated nyob rau hauv lub hnub ci thiab qhov cua zoo, uas tuaj yeem ua rau cov neeg hnav kom qhuav thiab xis nyob.
Kev tshem tawm noo noo ntawm cov ntaub feem ntau yog nyob ntawm lub cev qauv ntawm fiber ntau.Gaseous ya raws uas evaporates ntawm saum npoo ntawm daim tawv nqaij yog thawj absorbed los ntawm cov ntaub (xws li hygroscopic, —- Nco ntsoov tias nws yog cov ntaub uas hygroscopic, tsis yog fiber!).Tom qab ntawd cov nyhuv capillary tsim los ntawm lub qhov (pores, micropores, grooves) hauv cov fibers thiab qhov sib txawv ntawm cov fibers ua rau cov dej noo adsorption thiab diffusion ntawm cov ntaub.Nyob rau hauv txoj kev no, noo noo migrate mus rau saum npoo ntawm cov ntaub thiab evaporates, yog li ua tiav cov txheej txheem ntawm ya raws.
Yog li, noo noo nqus ib leeg tsis txaus.Rau qee cov khoom siv hluavtaws zoo tib yam, tsuas yog tom qab ua tiav nrog hydrophilic additives, thiab tom qab ntawd tshaj tawm tias hygroscopic "hws" ua rau peb txhua tus nkag siab yuam kev.
Hauv kev tsim cov khoom siv hluavtaws, qhov tshwj xeeb ntawm thaj chaw ntawm cov fiber ntau tuaj yeem txhim kho los ntawm kev hloov cov duab ntawm spinneret qhov thiab tsim ntau grooves nyob rau hauv longitudinal kev taw qhia ntawm fiber.Qhov no txhim kho cov dej noo conductivity ntawm cov fiber ntau thiab ua tiav perspiration los ntawm cov ntsiab lus nqus ntawm cov grooves.Piv txwv li, Invista tsim polyester rau COOLMAX® hygroscopic thiab perspiratory ntaub ntawv pov thawj.Nws hla ntu yog qhov sib txawv ntawm tus ntoo khaub lig zoo, lub fiber nto yog lengthwise mus rau hauv plaub grooves.Nws thaj chaw tshwj xeeb yog 20% loj dua li cov pa puag ncig, yog li nws qhov kev ua pa tawm siab dua li cov pa polyester.
Kev saib xyuas tshwj xeeb yuav tsum tau them rau: Vim yog kev ua tiav, ntu ntu ntawm cov ntaub hauv cov tsoos tsho tau raug puas tsuaj heev (ua rau cov yas deformation), yog li cov hws tawm hws tau zoo heev.Invista tus tshiab "C, C, O, O" hom polyester tuaj yeem txo cov yas deformation mus rau qhov loj, thiaj li ua kom lub zog tawm hws ntau tshaj plaws —–C qhia zawj tsis yooj yim deformed.Tsis tas li ntawd, rau cov neeg siv khoom, kev ua haujlwm ntawm cov xov paj yog qhov tseem ceeb, tab sis qhov zoo thiab kev ua haujlwm ntawm cov ntaub yog qhov tseem ceeb dua los xyuas kom meej cov kev ua haujlwm ntawm cov tsoos tsho.
