Kuki uruhu rw'impimbano ari rwiza kurusha uruhu karemano

Bitewe n'imiterere yayo myiza karemano, ikoreshwa cyane mu gukora ibintu bikenerwa buri munsi n'ibicuruzwa by'inganda, ariko uko abatuye isi biyongera, abantu bakenera uruhu rwikubye kabiri, kandi umubare muto w'uruhu karemano umaze igihe kinini utarashobora guhaza ibyo abantu bakeneye. Kugira ngo bakemure uku kutumvikana, abahanga mu bya siyansi batangiye gukora ubushakashatsi no guteza imbere uruhu rw'ubukorano n'uruhu rw'ubukorano mu myaka yashize kugira ngo basubize ikibazo cy'ibura ry'uruhu karemano. Imyaka irenga 50 y'ubushakashatsi ni inzira y'uruhu rw'ubukorano n'uruhu rw'ubukorano ihangana n'uruhu karemano.

Abahanga mu bya siyansi batangiye biga kandi bagasesengura imiterere n'imiterere y'uruhu karemano, bahereye ku mwenda wasizwe na nitrocellulose, binjira mu ruhu rw'ubukorano rwa PVC, ari na rwo ruhu rwa mbere rw'ubukorano. Kuri iyi ngingo, abahanga mu bya siyansi bakoze byinshi mu kunoza no gushakisha, icya mbere ni ukuvugurura substrate, hagakurikiraho guhindura no kunoza resin yo gusiga. Mu myaka ya 1970, imyenda idafunze ya fibres sintetike yagaragayemo acupuncture, bonding n'izindi nzira, ku buryo substrate yari ifite igice gisa na lotus n'imiterere y'umugozi, igera ku miterere y'uruhu karemano. Ibisabwa: Muri icyo gihe, urwego rw'ubuso rw'uruhu rusanzwe rushobora kugera ku urwego rwa polyurethane rufite imyenge mito, rungana n'ubuso bw'uruhu karemano, ku buryo imiterere n'imiterere y'imbere y'uruhu rusanzwe rwa PU bigenda byegerana n'iby'uruhu karemano, kandi indi miterere y'uruhu karemano igera hafi y'uruhu karemano. Ibara rirabagirana kurusha uruhu karemano; ubushobozi bwo kuzingira ku bushyuhe bw'icyumba bushobora kugera ku nshuro zirenga miliyoni, kandi ubushobozi bwo kuzingira ku bushyuhe buke bushobora no kugera ku rwego rw'uruhu karemano.

Nyuma y’uruhu rw’ubukorano rwa PVC, uruhu rw’ubukorano rwa PU rwageze ku iterambere rikomeye mu ikoranabuhanga nk’urusimbura uruhu karemano nyuma y’imyaka irenga 30 rw’ubushakashatsi n’iterambere byakozwe n’inzobere mu bya siyansi n’ikoranabuhanga.

Irangi rya PU ku buso bw'umwenda ryagaragaye bwa mbere ku isoko mu myaka ya 1950, maze mu 1964, DuPont ikora uruhu rwa PU rukozwe mu nkweto. Nyuma y'imyaka irenga 20 y'ubushakashatsi n'iterambere rihoraho, uruhu rwa PU rukozwe mu nganda rwakuze cyane mu bijyanye n'ubwiza bw'ibicuruzwa, ubwoko n'umusaruro. Imikorere yarwo igenda yegereza cyane uruhu rusanzwe, ndetse hari n'imiterere irenze uruhu rusanzwe, ikagera ku rwego rudashobora gutandukana n'uruhu rusanzwe, kandi rufite umwanya ukomeye cyane mu buzima bwa buri munsi bw'umuntu.

Uruhu rwa microfiber polyurethane rukozwe mu nganda ni uruhu rw’ubukorano rwa gatatu rwagaragaye mu masoko yo mu gihugu no mu mahanga. Urwo ruhu rudakozwe mu nganda eshatu rutuma uruhu rw’ubukorano rurusha uruhu karemano mu bijyanye n’imiterere yarwo. Iki gicuruzwa gihuza impu nshya ya PU iterwa n’imiterere y’imyobo ifunguye hamwe n’ikoranabuhanga ryo gutunganya urwego rw’ubuso buvanze, rutanga ubuso bunini kandi rufata amazi menshi mu nganda nziza, bigatuma uruhu rwa superfine rukozwe mu nganda za PU hamwe n’uruvange rw’inganda nziza. Imiterere y’uruhu karemano rw’inganda za collagen ishobora kugereranywa n’uruhu karemano rwo mu rwego rwo hejuru mu bijyanye n’imiterere y’imbere, imiterere, imiterere n’imiterere y’umubiri, ndetse n’uburyo abantu bambara neza. Byongeye kandi, uruhu rwa microfiber rukozwe mu nganda rurusha uruhu karemano mu kurwanya imiti, uburinganire, gukora no gutunganya ibintu mu buryo bunini, no kwirinda amazi no kwangirika.

Ibimenyetso byagaragaje ko imiterere myiza y'uruhu rw'ubukorano idashobora gusimburwa n'uruhu rw'umwimerere. Mu isesengura ry'amasoko yo mu gihugu no mu mahanga, uruhu rw'ubukorano rwasimbuye umubare munini w'uruhu rw'umwimerere nta bushobozi buhagije rufite. Ikoreshwa ry'uruhu rw'ubukorano n'uruhu rw'ubukorano nk'imitako y'imizigo, imyenda, inkweto, imodoka n'ibikoresho byo mu nzu byarushijeho kwemerwa n'isoko.
