Cov khoom ntawm paj rwb fiber
Cov paj rwb fiber ntau yog ib qho tseem ceeb tshaj plaws ntawm ntuj textile fibers ntawm cov nroj tsuag keeb kwm thiab suav txog li ib feem peb ntawm tag nrho lub ntiaj teb tsim ntawm textile fibers.Paj rwb fibers loj hlob nyob rau saum npoo ntawm cov noob ntawm paj rwb.Cov paj rwb fiber ntau muaj 90 ~ 95% cellulose uas yog cov organic compound nrog cov qauv dav dav (C6H10O5)n.Paj rwb fibers kuj muaj waxes, pectins, organic acids thiab inorganic tshuaj uas tsim tshauv thaum fiber ntau burnt.
Cellulose yog linear polymer ntawm 1,4-β-D-glucose units txuas ua ke los ntawm valence bonds ntawm cov pa roj carbon atoms naj npawb 1 ntawm ib cov piam thaj molecule thiab tooj 4 ntawm lwm molecule.Lub degree ntawm polymerization ntawm cellulose molecule tej zaum yuav siab li 10000. Cov hydroxyl pawg OH protruding los ntawm ob sab ntawm cov molecule saw txuas cov nyob sib ze chains ua ke los ntawm hydrogen daim ntawv cog lus thiab tsim ribbon zoo li microfibrils uas yog ntxiv mus rau hauv loj lub tsev blocks ntawm fiber. .
Cov paj rwb fiber ntau yog ib nrab crystalline thiab ib nrab amorphous;cov degree ntawm crystallinity ntsuas los ntawm X-ray txoj kev yog nyob nruab nrab ntawm 70 thiab 80%.
Qhov hla ntawm cov paj rwb fiber ntau zoo li lub raum taum 'zoo li qhov ntau txheej tuaj yeem pom tau raws li hauv qab no:
1. Cov phab ntsa sab nraud uas nyob rau hauv lem yog tsim ntawm cuticle thiab thawj phab ntsa.Lub cuticle yog ib txheej nyias ntawm waxes thiab pectins uas npog lub hauv paus phab ntsa uas muaj microfibrils ntawm cellulose.Cov microfibrils no tau npaj rau hauv lub network ntawm kauv nrog txoj cai- thiab sab laug-tes taw qhia.
2. Cov phab ntsa theem nrab yog tsim los ntawm ob peb concentric khaubncaws sab nraud povtseg ntawm microfibrils uas ib ntus hloov lawv angular orientation nrog rau cov fiber axis.
3. Lub hauv nruab nrab hollow yog lumen uas muaj cov seem qhuav ntawm cell nucleus thiab protoplasm.
