Lub hnab paj rwb yog ib hom kev tiv thaiv ib puag ncig lub hnab. Nws yog ib qho khoom siv niaj hnub. Nws yog me me, yooj yim, ruaj thiab tsis ua paug ib puag ncig. Lub hnab paj rwb kuj yog ib hom kev tiv thaiv ib puag ncig lub hnab, thiab hom no yog muag heev, yooj yim, ruaj, tuaj yeem degraded nyob rau hauv ib puag ncig ntuj, thiab yuav tsis ua phem rau ib puag ncig. Tau kawg, nws qhov zoo dua yog tias nws tuaj yeem rov qab siv tau ntau zaus thiab siv tau ntau dua li cov hnab tiv thaiv ib puag ncig zoo tib yam. Dab tsi yog cov yam ntxwv ntawm cov hnab paj rwb?
Dab tsi yog cov yam ntxwv ntawm cov hnab paj rwb?
1. Thaum tshav kub kub tsis kam: ntshiab paj rwb ntaub muaj kub zoo heev. Thaum qhov kub qis dua 110, nws yuav ua rau cov dej ntws mus rau cov ntaub thiab yuav tsis ua rau cov fiber ntau ua ke. Yog li ntawd, cov paj rwb ntshiab yog hnav thiab siv ntawm qhov kub thiab txias.
2. Kev huv huv: cov khoom siv raw ntawm cov ntaub paj rwb yog ntuj fiber ntau, thiab cov khoom tseem ceeb yog cellulose. Ntawm chav kawm, muaj ib tug me me ntawm waxy tshuaj, nitrogen-muaj tshuaj thiab pectin. Kev huv huv kuj zoo.
3. Hygroscopicity: lub hnab tiv thaiv ib puag ncig ua los ntawm paj rwb muaj hygroscopicity zoo heev. Cov fiber ntau no tuaj yeem nqus dej rau hauv qhov chaw ib puag ncig, nrog rau cov ntsiab lus dej ntawm 8-10 feem pua, yog li nws zoo li mos tab sis tsis tawv thaum nws los rau hauv tib neeg daim tawv nqaij.
4. Moisture retention: paj rwb fiber ntau yog ib tug tsis zoo conductor ntawm tshav kub thiab hluav taws xob, uas tsis tshua muaj thermal conductivity. Tsis tas li ntawd, paj rwb fiber nws tus kheej muaj porosity. Piv txwv li, fiber ntau tuaj yeem khaws cua ntau. Qhov tseeb, huab cua yog qhov tsis zoo ntawm cov cua sov thiab hluav taws xob. Yog li ntawd, ntshiab paj rwb fiber ntau textiles muaj zoo noo noo tuav.
