Cov ntawv phaj qab zib yog ua los ntawm cov khoom qab zib ntuj fibers, thiab nws cov qauv fiber ntau tso cai rau lub phaj kom degrade ib txwm muaj nyob rau hauv ib puag ncig tsim nyog yam tsis muaj kuab paug rau ib puag ncig.
Cov txheej txheem fiber ntau ntawm cov ntawv nplaum nplaum ua rau nws muaj lub zog zoo thiab lub zog, tsis yooj yim rau deform lossis tawg, thiab tuaj yeem tiv taus qhov hnyav thiab kub ntawm ntau yam khoom noj.
