Nyom pulp ntawv yog siv los tsim cov ntawv ntim qis, ntawv tso quav tso quav thiab lwm yam.
4. hemp pulp
Hemp pulp yog ua los ntawm flax, jute thiab lwm yam hemp nroj tsuag ua raw cov ntaub ntawv. Hemp cog fibers ntev, muaj zog, ua los ntawm cov ntawv hemp nrog cov kua muag zoo thiab ua haujlwm ntev, tshwj xeeb tshaj yog tsim rau kev tsim cov ntawv ntim qib siab, ntawv banknote thiab qee cov ntawv tshwj xeeb.
5. Paj rwb pulp
