Utoto ndi Makhalidwe a Nsalu Zopangidwa ndi Ubweya Wosayerekezeka

Nsalu ya ubweya wotsanzira imatanthauza nsalu za ulusi wa mankhwala zomwe zimafanana ndi nsalu za ubweya. Zimapangidwa makamaka kuchokera ku zipangizo zopangira ulusi wa mankhwala monga polyester/viscose ndi polyester/acrylic. Pogwiritsa ntchito njira yomaliza yopangira ubweya wotayirira, nsalu zotsika mtengo zimapangidwa. Kapangidwe kake kofala kwambiri ndi 2/2 twill ndi 3/1 twill.

Njira yopaka utoto wa nsalu zopyapyala za ubweya wofanana ndi wachizolowezi imasiyana ndi njira yopaka utoto wa nsalu wamba, ndipo imagwiritsa ntchito njira yopaka utoto wa masterbatch. Zinthu zofunika kwambiri za ukadaulo wopaka utoto wa masterbatch ndi izi: imapereka kufalikira kwabwino ndi utoto wa tinthu ta pigment mofanana pansi pa 1 μm, zomwe zimaletsa kukhuthala kwa tinthu tating'onoting'ono ta pigment tikamakumana ndi mpweya kutentha; zimathandiza kuti utoto ukhale wosavuta komanso kufananiza mitundu mosavuta, ndipo ma masterbatches amitundu yosiyanasiyana amatha kusinthidwa; amatha kusakanikirana ndi zowonjezera zina (monga zoletsa moto ndi zoletsa kukalamba) kuti apange ma masterbatches okhala ndi ntchito zapadera, ndipo sayambitsa kuipitsa fumbi.

Nsalu za ubweya woipa kwambiri nthawi zambiri zimagwiritsa ntchito ulusi woipa kwambiri wokhala ndi ulusi wopota pang'ono komanso wopota pang'ono. Nsalu ya imvi imakhala yomasuka yokhala ndi mizere yosiyana yoluka, ndipo ulusi wa warp ndi weft ukhoza kulekanitsidwa mosavuta. Nsalu ya imvi imawoneka yotsika, koma imasintha kwathunthu ikamalizidwa. Pali kusiyana kwakukulu pakati pa nsalu ya imvi ndi chinthu chomalizidwa, mosiyana ndi nsalu zopota zomwe nsalu yake ya imvi ndi chinthu chomalizidwa zimakhala ndi miyeso yofanana. Nsalu za ubweya woipa kwambiri nthawi zambiri zimalukidwa kuchokera ku ulusi umodzi, ndipo mitundu yochepa imagwiritsa ntchito ulusi wopota. Mosiyana ndi zimenezi, nsalu za ubweya woipa kwambiri zimalukidwa ndi ulusi wopota; mitundu ingapo imagwiritsa ntchito ulusi wopota pang'ono ngati ulusi wa warp ndi ulusi umodzi ngati ulusi wa weft, kapena imagwiritsa ntchito ulusi umodzi ngati ulusi wa warp ndi weft.
