Los ntawm txoj kev xav, kev tsim khoom ntawm Roma npuag cia siab rau ob lub -sab ncig knitting tshuab. Los ntawm kev kho qhov tsis xws li rab koob suav piv ntawm lub tog raj kheej thiab rab koob phaj, cov xov paj pub, thiab lub voj ntev, qhov sib txawv ntawm lub voj ntom ntom ntawm sab xub ntiag thiab sab nraub qaum ntawm cov ntaub yog tswj. Cov loops pem hauv ntej yog denser, tsim ib tug du nto; cov rov qab loops kuj xoob, tsim longitudinal grooves. Cov qauv no muab cov ntaub ob qho tib si crispness thiab elasticity. Nws pom zoo resilience thaum stretched tom qab, thaum tuav tus txheeb ze stability longitudinally, tsis txhob deformation teeb meem ntawm zoo tib yam knitted fabrics.
Muab ob npaug -sided Rib Structure: Roma ntaub yog woven rau ntawm ib ob -sided ncig knitting tshuab, siv plaub- txoj kev voj los ua ib tug ob chav tav qauv. Cov qauv no muab cov ntaub symmetry thiab ruaj khov, nws txawv ntawm tib yam nkaus xwb -sided lossis ob - sab tsho ntaub.
Lub Cev Elasticity Tsis Muaj Tshuaj Txheej Txheej: Nws elasticity thiab drape tsis yog nyob ntawm cov txheej txheej tiav, tab sis ua tiav los ntawm kev sib koom ua ke ntawm cov xov paj twist, loom nro, thiab weave tsim. Yog li ntawd, nws tsis yooj yim ua nruj tom qab ntxuav; Hloov chaw, nws ua softer nrog hnav.
