1, Kurwanya kuzunguruka no kuzunguruka: ni byiza cyane nk'uruhu rusanzwe, nta mvune mu kuzunguruka inshuro 200.000 ku bushyuhe busanzwe, inshuro 30.000 nta mvune kuri -20°C.
2, Ijanisha rikwiye ry'uburebure (urukozasoni rwiza rw'uruhu)
3, Ikomeye cyane mu gushwanyagurika no gushishwa (Irashya cyane/irakomera cyane mu gushishwa)
4, Kutarinda umwanda uwo ari wo wose kuva ku musaruro kugeza ku ikoreshwa, kandi ntibibangamira ibidukikije.
Microfibers isa cyane n'uruhu nyarwo. Nubwo ubunini, imbaraga zo gucika, amabara meza, ikoreshwa ry'ibikoresho ari byiza kurusha uruhu nyarwo, ni byo bizagenderwaho mu gihe kizaza ku ruhu rw'ubukorikori. Ushobora gukoresha lisansi yo mu rwego rwo hejuru cyangwa amazi meza kugira ngo uyisukure niba hari umwanda ku buso bwa mifrofiber, ariko ukabuza kuyisukura n'ibintu bisukura cyangwa ikindi kintu cyose gifite alkaline bizagira ingaruka ku bwiza. Imiterere yo kuyikoresha: Ntibirenze iminota 25 mu bushyuhe bwa 100℃, iminota 10 kuri 120℃, iminota 5 kuri 130℃.
Kubera 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 ingano nto y'uruhu karemano ntishobora guhaza ibyifuzo by'abantu. 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 batunganye inenge z'uruhu karemano. Inzira y'amateka y'ubushakashatsi imaze imyaka irenga 50 ni inzira y'uruhu rw'ubukorano n'uruhu rw'ubukorano irwanya uruhu karemano.
Abahanga mu bya siyansi batangiye bakora ubushakashatsi no gusesengura imiterere y’imiti n’imiterere y’uruhu karemano, bahereye ku mwenda wasizwe na nitrocellulose, binjiza uruhu 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, babanje kunoza substrate, hanyuma bahindura kandi bavugurura resin yo gusiga. Mu myaka ya 1970, imyenda idakozwe mu budodo bw’ubudodo yashyizwe mu ruziga, ihuzwa n’inshundura, nibindi, ku buryo ibikoresho by’ibanze byari bifite igice gisa n’umutuku, imiterere y’ubudodo bw’ubudodo, kandi bigera ku buryo bufite imyenge, byari bihuye n’imiterere y’uruhu karemano. Ibisabwa; Muri icyo gihe, urwego rw’ubuso rw’uruhu rw’ubudodo rushobora kugera ku rwego rwa polyurethane rufite imyenge mito, rungana n’impeta y’uruhu karemano, ku buryo imiterere n’imiterere y’imbere y’uruhu rw’ubudodo rwa PU bigenda byegeranye n’iby’uruhu karemano, kandi indi miterere y’umubiri yegeranye n’iby’uruhu karemano. Ibara ry’uruhu, kandi ibara rirabagirana kurusha uruhu karemano; ubushyuhe bwarwo busanzwe bwo gupfunyika bushobora kugera ku nshuro zirenga miliyoni imwe, kandi ubushyuhe buke bwo gupfunyika nabwo bushobora kugera ku rwego rw’uruhu karemano.
Nyuma y’uruhu rw’ubukorano rwa PVC, uruhu rw’ubukorano rwa PU rwakoreweho ubushakashatsi kandi rutezwa imbere n’inzobere mu bya siyansi n’ikoranabuhanga mu gihe cy’imyaka irenga 30. Nk’urupapuro rwiza rwo gusimbura uruhu rusanzwe, uruhu rw’ubukorano rwa PU rwageze ku iterambere rikomeye mu ikoranabuhanga.
