Yuav Qhia Li Cas Yog Koj Cov Khaub Ncaws Breathable?

Txhais ntawm Breathability

Breathability yog hais txog permeability ntawm gases los ntawm cov ntaub ntawv polymer xws li films, coatings, thiab fabrics.

Fabric breathability hais txog lub peev xwm ntawm huab cua kom dhau los ntawm cov ntaub thaum muaj qhov sib txawv ntawm nws ob sab. Tshwj xeeb, nws ntsuas qhov ntim ntawm huab cua uas ntws los ntawm ib cheeb tsam ntawm cov ntaub ntawm ib chav tsev ib lub sij hawm nyob rau hauv ib tug tshwj xeeb siab sib txawv, feem ntau qhia nyob rau hauv units ntawm mm / s. Lub siab sib txawv yog qhov tsim nyog rau huab cua ntws; tsuas yog thaum muaj qee qhov sib txawv ntawm qhov sib txawv ntawm ob sab ntawm cov ntaub tuaj yeem ua cua ntws los ntawm nws. Breathability cuam tshuam rau kev nplij siab ntawm cov khaub ncaws, xws li rwb thaiv tsev thiab sov so. Nws kuj yog ib txoj hauv kev tseem ceeb rau tib neeg lub cev kom dissipate tshav kub, noo noo vapor, carbon dioxide, thiab lwm yam gases.

Tej yam cuam tshuam rau Fabric Breathability

Fabric-txog yam:

1. Fiber morphology thiab xov paj qauv. Thaum cov linear ceev ntawm warp thiab weft yarns thiab cov kev ceev ceev ntawm warp yarns yog tib yam, fabrics ua los ntawm profiled fibers outperform cov uas ua los ntawm lub voj voog -section fibers. Npuag nrog tuab ib fibers pom zoo breathability dua cov uas nyias nyias.

2. Npuag weave qauv. Nyob rau hauv tib txoj kev ceev thiab nruj, qhov kev txiav txim ntawm breathability los ntawm weakest mus rau lub zog tshaj yog tiaj weave < twill weave < satin weave < porous weave.

3. Tshaj tawm -kev kho kom tiav. Cov txheej txheem dyeing thiab xov ua kom nruj cov qauv ntaub, txo qis breathability. Kev kho qhov hnyav txo kom nyias cov fibers thiab ua kom qhov sib txawv ntawm fibers thiab yarns, yog li ua kom muaj pa.

Environmental Factors:

1. Ntawm qhov kub thiab txias, qhov breathability ntawm cov ntaub yuav txo qis raws li qhov txheeb ze av noo ntawm huab cua nce. Thaum cov ntaub nqus dej noo, cov fibers swell, thiab cov pores cog lus, txo qhov khoob hauv thiab thaiv cov ntaub lub qhov hws, ua rau kom tsis txhob ua pa.

2. Ntawm cov av noo tsis tu ncua, qhov ua pa ntawm cov ntaub yuav nce ntxiv thaum qhov kub ntawm ib puag ncig nce. Lub zog thermal zog ntawm cov roj molecules txhim kho lawv cov peev xwm diffusion.

3. Thaum qhov kub thiab txias ntawm cov av noo nyob twj ywm tsis hloov, kev hloov pauv ntawm huab cua siab (P) ntawm ob sab ntawm cov ntaub yuav cuam tshuam rau qhov ntsuas qhov ntsuas, thiab cov nyhuv no yog nonlinear.
