Hauv kev soj ntsuam ntawm cov fibers , cov thawj thiab tseem ceeb tshaj plaws hauv kev xeem yuav yog: Fibers muab los ntawm ntuj los yog hluavtaws polymers; cov fibers feem ntau yog tsim los ntawm kev yuam cov khoom siv polymeric los ntawm lub qhov ntawm spinneret.
Kuj nug, dab tsi yog thawj kauj ruam hauv txheej txheem qhia plaub hau?
Cov thawj kauj ruam ntawm qhov kev xeem suav nrog txheeb xyuas seb puas yog plaub hau hauv nqe lus nug yog tib neeg lossis tsiaj.

Tsis tas li kom paub, dab tsi yog thawj kauj ruam hauv kev tshuaj xyuas kab mob ntshav qab zib?
Muaj tseeb lossis tsis tseeb: A. thawj theem hauv kev tshuaj ntsuam xyuas lub cev ntawm cov fibers yog los sib piv xim thiab txoj kab uas hla. Microspectrophotometer ntiav [dawb] lub teeb yog txoj hauv kev yooj yim rau cov kws tshuaj ntsuam sib piv cov xim rau fibers los ntawm cov qauv spectral.
Microspectrophotometry thiab chromatography tuaj yeem siv los txheeb xyuas cov pov thawj fiber ntau li cas?
Microspectrophotometry tuaj yeem ua tau ua siv los sib piv cov xim ntawm fibers los ntawm lawv cov qauv spectral. Polarizing microscope thiab infrared microspectrophotometer yog ob leeg siv los txiav txim siab chav kawm ntawm a fiber ntau.
