Kodi mukudziwa zingwe zazikulu zisanu ndi chimodzi za mankhwala? (Polypropylene, Vinylon, Spandex)

M'dziko la ulusi wopangidwa, vinylon, polypropylene ndi spandex onse ali ndi katundu wapadera ndi ntchito zomwe zimapangitsa kuti zikhale zoyenera pazinthu zosiyanasiyana ndi mafakitale.

Vinylon imadziwika chifukwa cha kuyamwa kwake kwachinyontho, kupangitsa kuti ikhale yabwino kwambiri pakati pa ulusi wopangira ndikupanga dzina loti "thonje lopangidwa." Katunduyu wa hygroscopic umapangitsa kuti ikhale yabwino kugwiritsidwa ntchito pazinthu zosiyanasiyana monga muslin, poplin, corduroy, zovala zamkati, chinsalu, tarps, zonyamula katundu ndi zovala zogwirira ntchito.

Komano, ulusi wa polypropylene, umaonedwa kuti ndi wopepuka kwambiri mwa ulusi wamankhwala wamba ndipo umatenga pang'ono kapena osanyowa. Izi zimapangitsa kuti zikhale zoyenera kugwiritsa ntchito zosiyanasiyana, kuphatikizapo masokosi, maukonde a udzudzu, ma quilts, zodzaza mafuta ndi matewera. M'mafakitale, polypropylene imagwiritsidwa ntchito m'makapeti, maukonde ophera nsomba, zinsalu, mapaipi amadzi, ngakhale tepi yachipatala kuti ilowe m'malo mwa thonje yopyapyala ndikupanga zinthu zaukhondo.

Pakalipano, spandex imadziwika chifukwa cha kusungunuka kwake kwapamwamba, ngakhale kuti imakhala yochepa kwambiri komanso imakhala yochepa kwambiri. Komabe, imakhala ndi kukana kwabwino kwa kuwala, asidi, alkali ndi abrasion, zomwe zimapangitsa kuti zikhale zofunikira zowonjezera zowonjezera zowonjezera zovala za zovala zapamwamba zomwe zimayika patsogolo mphamvu ndi zosavuta. Ntchito zake zimatengera nsalu ndi zamankhwala ndipo, chifukwa cha mawonekedwe ake apadera, zitha kugwiritsidwa ntchito muzovala zamkati, zovala zamkati, zovala wamba, masewera, masokosi, pantyhose ndi mabandeji.

Ulusi wopangirawu umagwira ntchito yofunika kwambiri m'mafakitale osiyanasiyana ndipo umapereka zosankha zingapo kwa opanga ndi ogula. Kaya ndi hygroscopic properties za vinylon, kupepuka ndi kutentha kwa polypropylene, kapena kusungunuka kwa spandex, ulusiwu ukupitirizabe kukhudza kupanga ndi kugwira ntchito kwa zinthu kuyambira zovala mpaka mankhwala.
