Kuva mu gitondo cy'ikinyejana cya 21, iterambere ryaumwenda udafunze ushongeshejweku isi yagiye itera imbere ku buryo burenze urugero.
Isosiyete ya Hills na Isosiyete ya Nordson yo muri Leta Zunze Ubumwe za Amerika bashoboye guteza imbere ikoranabuhanga rya meltblown rifite ibice bibiri mbere, harimo ubwoko bw'inyuma bw'uruhu, ubwoko bwo ku ruhande, mpandeshatu, nibindi, muri rusange ubunini bwa fibre buri hafi ya 2 & micro;, umubare w'imyobo kuri santimetero imwe y'ibintu bizunguruka bya meltblown ushobora kugera ku myobo 100, ingano ya extrusion ya buri mwobo ishobora kugera kuri 0.5 g / min.

Ubwoko bw'inyuma y'uruhu. Ishobora gutuma umwenda udakoze mu ruhu wumva woroshye kandi ishobora gukorwamo ibintu bifatanye, bidasanzwe kandi bifite imiterere yihariye. Muri rusange, ibikoresho bihendutse bikoreshwa nk'inyuma y'umubiri, kandi polymeri z'agaciro zifite uduce twihariye cyangwa twasabwe ni zo ruhu rwo hanze. Urugero, inyuma ni polypropylene, naho uruhu rwo hanze ni nylon kugira ngo rukore fibre hygroscopic; Polyethylene yo mu mazi cyangwa polypropylene yahinduwe, polyester yahinduwe, nibindi. Ku binyabutabire by'umukara wa karuboni, inyuma y'umubiri ipfundikirwa hanze.
Ubwoko bwo ku ruhande. Ishobora gutuma umwenda utari uwo ku ruhande ugira ubushobozi bwo koroha neza. Muri rusange ukorwa muri polimeri ebyiri zitandukanye, cyangwa polimeri imwe ifite ubucucike butandukanye. Ifite ubushobozi bwo koroha. Urugero, 3M Company yakoze umwenda utari uwo ku ruhande w’udupira tw’ibice bibiri bya PET/PP bivanze. Bitewe n’igihombo gitandukanye, hakorwa umugozi wo ku ruhande, bigatuma umwenda utari uwo ku ruhande ugira ubushobozi bwo koroha neza.

Ubwoko bw'agace k'umugozi. Ibi bigamije guhuza indi polimeri mu bwoko bwa trilobal, ubwoko bwa cross na tip. Urugero, mu gihe cyo gukora imigozi irwanya static, iyobora ubushuhe, n'iyobora amashanyarazi, polimeri iyobora amashanyarazi ishobora guhuzwa ku gace k'umugozi, ishobora gutwara ubushuhe no gutwara amashanyarazi, irwanya static, kandi ikabika quantum ya polimeri iyobora amashanyarazi.
Ubwoko bwa micro-denier Ishusho y'ururabo rw'umuhondo, ifite ishusho y'imirongo, cyangwa modules zo mu nyanja zishobora gukoreshwa. Polima ebyiri zitagira ingano zikozwe kugira ngo hakorwe imiyoboro ya fibre ikoze neza cyane, cyangwa koko imiyoboro ya nanofiber, isa n'imiyoboro ya bicomponent yakozwe na Kimberly-Clark, ari yo miyoboro ibiri ikozwe muri polima ebyiri zitagira ingano. Mu gice kiri munsi y'isegonda ry'ibice biri mu mazi ashyushye, polima ebyiri zishobora gukurwamo neza kugira ngo hakorwe imiyoboro ya microfiber. Ubwoko bwa islet bugomba gushonga inyanja kugira ngo haboneke urusobe rwiza rwa fibre ya islet.

Ubwoko bwa mongrel Ni urusobe rw'imigozi ruhuza ibintu bitandukanye, amabara atandukanye, imigozi itandukanye, imiterere itandukanye y'ibice, ndetse n'imigozi y'uruhu, imigozi yombi ivanze n'imigozi ibiri, kugira ngo imigozi ibe ifite uduce dukenewe. Ugereranije n'ibicuruzwa rusange bya fibre ivanze, ubu bwoko bw'imyenda ibiri ivanze cyangwa imigozi ivanze ishobora kongera ubushobozi bwo kuyungurura imigozi, kandi bigatuma imigozi ivanze idafite amashanyarazi, ikora neza, irushaho kunoza imigozi, nibindi cyangwa ikongera uburyo bwo guhuza, ubwinshi n'umwuka wo kwinjira mu rusobe rw'imigozi.

Uduce duto tw’ibice bibiri dushobora gukurura imikorere ya polimeri imwe. Urugero, polipropylene irahendutse cyane, ariko iyo ikoreshejwe mu bikoresho by’ubuvuzi, ntabwo irwanya imirasire. Muri ubu buryo, polipropylene ishobora gukoreshwa nk’ishingiro ry’umubiri kandi hashobora kwitwa ubwoko bw’inyuma bw’umubiri. Ikibazo cyo kurwanya imirasire gishobora gukemurwa no gushyira polimeri irwanya imirasire inyuma. Bityo, ibicuruzwa bishobora kugurwa kandi bigahura n’imiterere y’imikorere, nk’iy’ubushyuhe n’ubushuhe bishobora gukoreshwa mu buryo bw’ubuhumekero mu rwego rw’ubuvuzi, kandi bigatanga ubushyuhe n’ubushuhe bisanzwe nk’ibisanzwe. Ni iy’umutuku, ikoreshwa cyangwa yoroshye kuyikuraho, ihendutse, kandi ikora nk’umukungugu mushya wo gukuraho imyanda. Igizwe n’udupira tubiri duto tw’ibice bibiri bivanze. Ikoresha fibre y’ibice bibiri, ishingiro ni polipropylene, naho uruhu ni nylon. Uduce tw’ibice bibiri dushobora kandi gukoresha ibice byihariye by’imiterere, nk’ibice bya trilobal na multi-lobed, kugira ngo ubuso bw’isura bube bunini, kandi icyarimwe, polymer zishobora kunoza imikorere yo kuyungurura zishobora gukoreshwa mu gice cy’isura cyangwa igice cy’umutwe. Uduce twa Olefin cyangwa polyester meltblown two component fiber webs dushobora gukorwamo imyanda y’amazi n’imyuka ihumanya. Uduce tw’ibice bibiri by’umunyu dushobora kandi gukoreshwa ku mutwe w’itabi; gukoresha uburyo bwo kuyungurura kugira ngo ushyiremo igice cyo hejuru cy’inkuru; inkoni yo kuyungurura kugira ngo igumane amazi no kuyashyiramo, nibindi.
