Ikirango cya JADE “CZ-502” cya semi-Udupira twa polyester dull turakwiriye gukora filament ya terylene na filament ya terylene, PET industry film nibindi. Ubwo bwoko bwa semi dull chips bufite imiterere yoroshye, ingano y'udupira duto, umwanda muke kandi buhamye. Kugira ngo hakoreshwe uburyo bwihariye bwo gukora no gukora ikoranabuhanga, uburemere bwa molekile ya chip bukwirakwira mu buryo buhuriweho. Bityo, utwo dupira dukoreshwa cyane cyane mu gukora filament nziza ya denier na filime ya polyester yihuta cyane hamwe n'ubushobozi bwiza bwo gutunganya, imikorere ya chromaticity, igipimo cyo hejuru cy'ibicuruzwa bya nyuma, igipimo gito cya filament cyangiritse.
