1. Fibre ya Spandex
Fibre ya Spandex (izwi nka fibre ya PU) ni iy'imiterere ya polyurethane ifite uburebure bwinshi, modulus nkeya kandi ifite umuvuduko wo kugarura ubushyuhe bwinshi. Byongeye kandi, spandex ifite ubushobozi bwo kudahinduka no guhagarara neza mu bushyuhe. Irwanya cyane imiti kurusha ubudodo bwa latex. Kwangirika, ubushyuhe bwo koroshya buri hejuru ya 200 ℃. Fibre ya Spandex irwanya ibyuya, amazi yo mu nyanja n'ibindi bikoresho by'isuku byumye ndetse n'imiti myinshi yo kwisiga izuba. Kubona izuba ryinshi cyangwa chlorine bleach igihe kirekire nabyo bishobora gucika, ariko urwego rwo gucika rutandukanye cyane bitewe n'ubwoko bwa spandex. Imyenda ikozwe mu mwenda urimo spandex igumana imiterere myiza, ingano ihamye, nta gitutu kandi yoroshye kwambara. Ubusanzwe, 2% kugeza kuri 10% bya spandex gusa ni byo bishobora kongerwamo kugira ngo imyenda y'imbere yoroshye kandi yegereye umubiri, iruhuke kandi ibe nziza, ituma imyenda ya siporo ikwirana neza kandi ikagenda neza, kandi bigatuma imyenda y'imyambarire n'imyenda isanzwe igira imiterere myiza, igumana imiterere n'imyambarire myiza. Kubwibyo, spandex ni fibre y'ingenzi mu iterambere ry'imyenda igumana imiterere myinshi.
2. Fibre ya polytrimeline tereftalate
Fibre ya Polytrimethylene terephthalate (mu magambo ahinnye: fibre ya PTT) ni igicuruzwa gishya mu muryango wa polyester. Ni iy'umugozi wa polyester kandi ni ikintu gisanzwe cya polyester PET. Fibre ya PTT ifite imiterere ya polyester na nylon, intoki zoroshye, ifite ubushobozi bwo gusimbuza neza, yoroshye gusiga irangi mu gihe gisanzwe, ifite ibara ryiza, ifite ubushobozi bwo kugumana neza mu mwenda, ikwiriye cyane mu bijyanye n'imyenda. Fibre ya PTT ishobora kuvangwa, gusigwa no gusimbuza imyenda isanzwe cyangwa imyenda ikoze mu buryo bwa sintetike nk'ubwoya n'ipamba, kandi ishobora gukoreshwa mu myenda iboshye n'imyenda iboshye. Byongeye kandi, fibre ya PTT ishobora no gukoreshwa mu myenda y'inganda n'indi mirimo, nko gukora tapi, imitako, ubudodo n'ibindi. Fibre ya PTT ifite ibyiza by'umugozi wa spandex, kandi igiciro kiri hasi ugereranyije n'umugozi wa spandex elastic. Ni fibre nshya yizewe.
Fibre ya 3.T-400
Fibre T-400 ni ubwoko bushya bw'ibicuruzwa bya fibre elastic byakozwe na DuPont kugira ngo bigabanya fibre ya spandex mu ikoreshwa ry'imyenda. T-400 ntabwo iri mu muryango wa spandex. Izungurutswa iruhande rw'ibice bibiri bya polymer, PTT na PET, bifite igipimo gitandukanye cyo kugabanuka. Ni fibre ivanze ku ruhande. Ikemura ibibazo byinshi bya spandex nko gusiga irangi bigoye, guhindagurika cyane, kuboha bigoye, ingano idahindagurika y'imyenda no gusaza kwa spandex mu gihe cyo kuyikoresha.
Imyenda ikozwe muri yo ifite ibi bikurikira:
(1) Uburyo bworoshye bworoshye, bworoshye kandi buramba; (2) Igitambaro cyoroshye, gikomeye kandi gifite isura nziza; (3) Igitambaro kiringaniye kandi kirwanya iminkanyari neza; (4) Gufata amazi no kuma vuba, intoki zigakomera neza; (5) Gukomera neza kandi byoroshye gufata.
T-400 ishobora kuvangwa n'imyenda karemano n'imyenda yakozwe n'abantu kugira ngo yongere imbaraga n'ubukonje, imiterere y'imyenda ivanze ni myiza kandi irasobanutse, imiterere y'imyenda irasobanutse, imyenda iracyashobora kugumana imiterere myiza nyuma yo kumesa kenshi, imyenda ifite ibara ryiza, ntiyoroshye gucika, iramba. Yambaye nk'ishya. Kuri ubu, T-400 ikoreshwa cyane mu mapantalo, imyenda ya denim, imyenda ya siporo, imyenda y'abagore ihenze n'ahandi kubera imikorere yayo myiza yo kwambara.
Uburyo bwo gutwika ni ukumenya ubwoko bwa fibre hakoreshejwe itandukaniro mu miterere y’imiti y’imigozi itandukanye n’itandukaniro mu miterere y’imigozi ikorwa. Uburyo ni ugufata agace gato k’ibipimo bya fibre ukagatwika, ukitegereza witonze imiterere y’imigozi n’imiterere, ibara, ubworoherane n’ubukana bw’ibisigazwa, kandi icyarimwe ukumva impumuro nziza ikorwa na byo.
Imiterere y'imigozi itatu irashya
| ubwoko bwa fibre | hafi y'umuriro | umuriro w'urumuri | rekera umuriro | impumuro ishyushye | Ibiranga ibisigazwa |
| PU | kugabanya | gutwika | kwiyangiza | impumuro idasanzwe | gelatinous y'umweru |
| PTT | kugabanya | gutwika | amazi ashongeshejwe agwa umwotsi w'umukara | impumuro ikaze | uduce tw'ibirahure by'umukara |
| T-400 | kugabanya | gutwika | Amazi ashyushye yashongeshejwe asohora umwotsi w'umukara | biryoshye | isaro rikomeye n'umukara |
Dufite ubuhanga muImyenda ya Viscose ya Polyetsercyangwa nta spandex, umwenda w'ubwoya, umwenda w'ipamba wa polyester, niba ushaka kumenya byinshi, murakaza neza twandikire!
