Kev ntsuam xyuas ntawm cov xov paj sib xyaw ua ke feem ntau suav nrog peb yam: kev tshuaj ntsuam xyuas muaj pes tsawg leeg, kuaj cov cuab yeej lub cev, thiab kev tshuaj xyuas qhov muag. Kev ntsuam xyuas kev sib xyaw feem ntau yog siv txoj hauv kev xws li kev soj ntsuam microscopic, chemical dissolution, lossis infrared spectroscopy txhawm rau txheeb xyuas hom fiber ntau thiab lawv qhov sib xyaw. Lub hom phiaj ntawm no yog los xyuas kom meej tias cov fiber ntau muaj raws li cov kev cai, yog li ua kom cov khoom sib xws ntawm qhov chaw.
Kev ntsuam xyuas lub cev yog tsom rau cov ntsuas tseem ceeb xws li xov paj lub zog, elongation, sib npaug, thiab twist. Cov khoom siv xws li cov xov paj lub zog testers thiab Uster testers feem ntau yog siv los ntsuas kev ua haujlwm ruaj khov thaum lub sijhawm xaws thiab xaus - siv. Tsis tas li ntawd, cov khoom zoo li pilling tendency thiab abrasion kuj raug soj ntsuam, raws li cov no cuam tshuam ncaj qha rau cov tsos thiab durability ntawm cov ntaub tiav.
Kev tshuaj xyuas qhov muag thiab kev kuaj xyuas kev ruaj ntseg zoo yog qhov tseem ceeb, suav nrog cov khoom xws li qhov smoothness thiab muaj cov plaub hau, pob caus, lossis xim txawv. Rau qhov loj - teev ntau lawm, batch sampling yog ua los xyuas kom meej sib xws nyob rau hauv txawv ntau lawm voj voog. Los ntawm ntau qhov - qhov kev sim ntsuas qhov no, qhov zoo ntawm cov xov paj sib xyaw tuaj yeem raug soj ntsuam zoo, muab lub hauv paus txhim khu kev qha rau yav tom ntej weaving thiab cov khoom siv.
