I-solvent esetshenziselwa ukuphotha kwejeli eyomile ngokuvamile i-decalin enephuzu eliphansi lokubila, ukuguquguquka okuphezulu nokuncibilika okuhle kwe-UHMWPE. I-UHMWPE kanye ne-decalin kuxutshwe kusixazululo esinokuhlanganiswa okungeqile ku-10% ku-extruder ye-twin-screw, bese kukhishwa nge-spinneret ukuze kufakwe iphaseji ye-nitrogen eshisayo ukuze kukhishwe izinyibilikisi. Ngemuva kokupholisa, kwakheka imicu yejeli eyomile, bese kuthi imicu ye-UHMWPE yenziwe ngezigaba eziningi zokwelula kwamandla ashisayo. Inqubo yokuphotha ijeli eyomile inzima ngokobuchwepheshe futhi idinga ukubekwa uphawu okuphezulu kwesistimu yokutakula, kodwa izinzuzo zayo ikakhulukazi ilele:
1. Inqubo emfushane, ukukhiqiza okuphezulu kanye nezindleko eziphansi.
2. I-solvent ingabuyekezwa ngokuqondile, okusebenza kangcono ekuvikelweni kwemvelo.
3. Ngaphansi kwezinye izimo ezifanayo, imicu elungiselelwe ngendlela eyomile ine-crystallinity ephakeme, izakhiwo zemishini, ukuphakama kwe-fiber ephakeme kanye nokuzinza okungcono kokushisa.
4. Inobuhle obuhle, umuzwa othambile kanye nezinsalela ze-solvent ephansi, futhi ifanele izinkundla zendwangu yezokwelapha nezasekhaya. Njengamanje, abakhiqizi abakhulu yi-DSM Company yaseNetherlands, iTOYOBO Company yaseJapan, kanye ne-Yizheng Chemical Fiber Company yaseSinopec.
Enqubweni yokukhiqiza yokuphotha okumanzi, uwoyela omhlophe onephuzu eliphezulu lokubila kanye nokuguquguquka okuphansi kusetshenziswa njengesinyibilikisi. Impushana ye-Ultrahigh incibilika emafutheni amhlophe ukuze kwenziwe isisombululo sesitoko sokuphotha. Ngemva kwalokho, ikhishwa ibe umcu owuketshezi ngokuphotha izingxenye. Khona-ke, ipholiswa emanzini okugeza ukuze yenze i-gel filament. I-gel filament iyakhishwa, yomiswe futhi ihlakazwe ukuze yakhe i-precursor enganwetshiwe, bese ishisa yelula izikhathi eziningana ukwenza i-fiber eqediwe. Ubuchwepheshe benqubo emanzi abunzima futhi budinga imishini encane. Njengamanje, amabhizinisi amaningi asekhaya asebenzisa inqubo yokuphotha emanzi, engakhiqiza imikhiqizo ye-fiber yezempi neyomphakathi enezinombolo ezihlukene zokuphika kanye namandla. Kodwa-ke, okugxilwe kukho ocwaningweni lwamanje lomzila wenqubo emanzi ukuthuthukisa umzila wenqubo okhona, ngokuqhubekayo ukuthuthukisa izakhiwo zemishini, ukuzinza nokusebenza kwefayibha, kugxile emikhiqizweni ephakathi nendawo kanye nesezingeni eliphansi. Njengamanje, abakhiqizi abakhulu yi-Honeywell Company e-United States, i-Beijing Tongyizhong Company e-China, kanye ne-Nantong Jiujiujiu Company.
