Qhov no txo ​​cov nqi zog thiab tshuab, thaum kawg txo qis tag nrho cov nqi tsim khoom.

Ntxiv mus, cov ntaub tsis-woven tuaj yeem tsim los ntawm ntau yam ntaub ntawv, suav nrog cov fibers ntuj xws li paj rwb thiab ntaub plaub, nrog rau cov khoom siv hluavtaws xws li polyester thiab polypropylene. Qhov kev ua tau zoo no tso cai rau cov tuam txhab xaiv cov khoom siv raws li qhov muaj thiab tus nqi, ntxiv rau kev txo nqi ntau lawm.

Tsis tas li ntawd, muaj peev xwm rov ua dua thiab rov siv qee yam ntawm cov fibers hauv cov khoom siv tsis-woven ua rau lawv cov nqi zoo. Recycled fibers tuaj yeem ua tiav thiab muab tso rau hauv cov ntaub tshiab uas tsis yog-woven, txo qhov xav tau cov ntaub ntawv nkauj xwb thiab txo cov nqi tsim khoom.
