Kapangidwe kabwino kaMa Scrims Oyikidwa:
Mzere umodzi
Iyi ndi njira yodziwika kwambiri yopangira ma scrim. Ulusi woyamba wa warp* pansi pa ulusi wa weft** umatsatiridwa ndi ulusi wa warp pamwamba pa ulusi wa weft. Kachitidwe aka kamabwerezedwa m'lifupi lonse. Nthawi zambiri malo pakati pa ulusiwo amakhala okhazikika m'lifupi lonse. Pamalo olumikizirana ulusi uwiri nthawi zonse umakumana.
* kupotoza = ulusi wonse munjira ya makina
** weft = ulusi wonse wopingasa
Kupindika kawiri
Ulusi wa pamwamba ndi pansi wopindika nthawi zonse uzikhala umodzi pamwamba pa unzake kuti ulusi wa weft uzikhala wokhazikika pakati pa ulusi wa pamwamba ndi wapansi wopindika. Pamalo olumikizirana ulusi utatu nthawi zonse umakumana.
Scrim nonwoven laminates
Chitsulo (chopindika chimodzi kapena ziwiri) chimayikidwa pa nsalu yopanda ulusi (yopangidwa ndi galasi, polyester kapena ulusi wina). N'zotheka kupanga ma laminates okhala ndi nsalu zopanda ulusi zolemera kuyambira 0.44 mpaka 5.92 oz./sq.yd.
