Cov ntawv tshwj xeeb yog cov ntsiab lus dav dav rau cov ntaub ntawv uas siv tshwj xeeb thiab cov khoom ntim me me, tseem hu ua tshwj xeeb - daim ntawv hom phiaj lossis daim duab kos duab, suav nrog 12 qhov loj xws li kab lis kev cai, ntim khoom, kev tsim kho, thiab kev kho mob. Nws cov ntaub ntawv raw muaj xws li cog fibers, hluavtaws fibers, thiab inorganic fibers. Los ntawm cov txheej txheem papermaking thiab txheej kev kho mob, nws tau txais txiaj ntsig nrog cov khoom xws li dej tsis qab, hluav taws kub, thiab cov khoom siv tshuaj tua kab mob. Piv txwv li, carbonless luam ntawv siv tshuab microencapsulation kom ua tiav nws txoj haujlwm luam, thiab nano- ntawv tsis muaj dej ua kom nws cov dej tsis zoo los ntawm kev ntxiv nanomaterials.
Cov pawg no tau los ntawm cov ntawv tsis muaj cov ntawv luam tawm hauv Tebchaws Meskas hauv xyoo 1940s. Txij li xyoo 2010, Tuam Tshoj txoj kev lag luam tau maj mam nthuav dav, mus txog qhov ntim ntawm 4.12 lab tons hauv xyoo 2022, tsim cov chaw lag luam hauv cheeb tsam hauv Quzhou thiab Zhutai Town. Kev tsim cov thev naus laus zis suav nrog cov qauv microencapsulation, kev ruaj ntseg xov tiv thaiv- cuav, thiab cov txheej txheem fiber ntau. Cov khoom lag luam suav nrog xeb- ntawv pov thawj, ntawv aramid, thiab ntawv-raws li cov ntaub thaiv npog, siv hauv kev tiv thaiv nyiaj txiag- cuav, cov khoom siv aerospace, thiab cov khoom siv hauv tsev. Kev lag luam ntsib cov teeb meem xws li nce nqi ntoo pulp thiab kev cia siab rau cov thev naus laus zis tuaj txawv teb chaws, thiab tab tom hloov mus rau ntsuab thiab qis - kev txhim kho carbon.
