Cellulose, ib qho polysaccharide uas muaj cov glucose monomers txuas nrog β-1,4-glycosidic bonds, yog cov organic polymer ntau tshaj plaws hauv ntiaj teb. Feem ntau pom muaj nyob rau hauv cov phab ntsa cell ntawm cov nroj tsuag, nws muab cov qauv rigidity, ua rau cov ntoo ncav cuag qhov siab thiab nplooj kom tswj tau lawv cov duab. Paj rwb, qhov chaw ntshiab tshaj plaws ntawm cellulose, muaj txog li 90% ntawm cov polymer no, thaum ntoo feem ntau muaj 40-50% cellulose, nrog rau lignin thiab hemicellulose. Algae thiab qee cov kab mob kuj tsim cellulose, nthuav nws qhov kev faib tawm ntuj.

Kev rho tawm cellulose suav nrog kev cais nws ntawm lwm cov khoom cog. Hauv kev lag luam pulp thiab ntawv, cov ntoo chips raug tshuaj lom neeg pulping (siv sulfates lossis sulfites) lossis kev sib tsoo tshuab kom tshem tawm lignin thiab cais cov cellulose fibers. Rau cov ntawv thov purity siab, xws li cov tshuaj thiab cov khoom noj khoom haus, cov kauj ruam purification ntxiv xws li bleaching thiab enzymatic kev kho mob siv. Nanocellulose, muab los ntawm cellulose los ntawm acid hydrolysis lossis mechanical fibrillation, tau tshwm sim ua cov khoom muaj nqis siab vim nws cov khoom tshwj xeeb ntawm nanoscale.

Cellulose muaj ntau yam siv tau rau ntau yam lag luam.kev tsim ntawv, cov cellulose fibers yog cov khoom siv raw tseem ceeb, muab lub zog thiab kev ywj pheej rau cov khoom ntawv. Hauvkev lag luam textile, paj rwb cellulose yog spin rau hauv cov xov thiab woven rau hauv cov ntaub, prized rau lawv cov breathability thiab xis nyob. Nyob rau hauvdaim ntawv thov zaub mov, cellulose ua haujlwm ua cov fiber ntau hauv kev noj haus, txhawb kev noj qab haus huv ntawm lub plab, thiab ua haujlwm ua cov khoom ua kom tuab, stabilizer, lossis emulsifier hauv cov khoom xws li ice cream thiab salad dressings.
