Cov pob fiber ntau yog cov khoom siv hauv eco-cov ntaub ntawv tus phooj ywg, nrog rau lawv cov txiaj ntsig zoo ib puag ncig los ntawm cov yam ntxwv ntsuab thoob plaws tag nrho cov txheej txheem ntawm kev xaiv raw khoom, ntau lawm thiab daim ntawv thov, nrog rau lawv cov peev txheej siv tau zoo. Cov ntaub ntawv raw yog feem ntau biodegradable natural plant fibers lossis ib puag ncig- cov ntaub ntawv polymer zoo li polypropylene thiab polyester.
Ib feem ntawm cov txheej txheem tsim khoom siv dej ua qhov nruab nrab, tsis txhob muaj cov kuab tshuaj organic ua kuab paug nkaus xwb, thiab cov khoom siv raw feem ntau yog muab los ntawm cov khoom siv biomass txuas ntxiv mus. Hauv daim ntawv thov, cov pob fiber ntau ua tiav pom los ntawm lub cev adsorption thiab cuam tshuam yam tsis tau ntxiv cov tshuaj tua kab mob, pab tiv thaiv cov dej paug thib ob. Kev siv dej rau kev rov qab tsuas yog suav txog 1% -3% ntawm tag nrho cov dej tso tawm thaum lub sijhawm ua haujlwm, txuag dej ntau.
Lub caij no, cov khoom siv fiber ntau muaj cov tshuab ua haujlwm siab thiab lub neej ua haujlwm ntev. Lawv tuaj yeem rov tsim dua tshiab thiab rov siv dua los ntawm kev rov qab ntxuav, tshuaj ntxuav thiab lwm txoj hauv kev, uas txo qhov zaus ntawm cov khoom siv lim hloov thiab tsim cov khoom pov tseg. Lawv tag nrho lub neej voj voog yog tag nrho raws li qhov yuav tsum tau ntawm ntsuab thiab kev txhim kho kom ruaj khov.
