Cov txheej txheem ntawm Modal npuag feem ntau suav nrog plaub theem: kev ua cov khoom siv raw, kev npaj fiber ntau, fiber ntau melting, thiab xov paj sib sau. Kev ua cov khoom nyoos muaj kev kho tshuaj kom tshem tawm cov impurities thiab lignin los ntawm cov ntoo, tau txais cov cellulose ntshiab. Kev npaj fiber ntau suav nrog kev noj cov tshuaj cellulose rau hauv fiber ntau- ua cov cuab yeej, qhov uas nws tau tsim rau hauv fibers los ntawm cov txheej txheem xws li tshuaj tsuag teb, spinning, thiab ncab. Fiber melting cuam tshuam cov fibers ntawm qhov kub thiab txias thiab tom qab ntawd yaj lawv mus rau hauv lub xeev molten siv airflow. Thaum kawg, cov molten fibers yog pub rau hauv lub tshuab spinning los tsim cov xov paj, tsim cov khoom tiav.
Thoob plaws hauv tag nrho cov txheej txheem tsim khoom, Modal ntaub siv cov fibers txuas dua tshiab ua cov khoom siv raw, ua rau muaj kev siv tshuaj tsawg thiab tsis muaj kuab paug ib puag ncig. Qhov no qhia tau hais tias ecological sustainability zoo ntawm Modal ntaub.
