1.Sibande ya fibre
Fibre ya spandex (yitwa fibre PU) ni iyimiterere ya polyurethane ifite uburebure burebure, modulus nkeya ya elastique hamwe nigipimo kinini cyo gukira.Mubyongeyeho, spandex ifite kandi imiti ihamye kandi ituje.Irwanya imiti kuruta silike ya latex.Gutesha agaciro, ubushyuhe bworoshye buri hejuru ya 200 ℃.Fibre ya spandex irwanya ibyuya, amazi yinyanja hamwe nisuku yumye hamwe nizuba ryinshi.Kumara igihe kinini kumirasire yizuba cyangwa chlorine byakuya nabyo birashobora gucika, ariko urugero rwo kugabanuka ruratandukanye cyane bitewe nubwoko bwa spandex.Imyenda ikozwe mu mwenda urimo spandex ifite imiterere myiza yo kugumana, ingano ihamye, nta gitutu kandi kwambara neza.Mubisanzwe, 2% kugeza 10% gusa ya spandex irashobora kongerwaho kugirango imyenda y'imbere yoroshye kandi yegereye umubiri, yorohewe kandi nziza, itume imyenda ya siporo ihuza neza kandi igenda yisanzuye, kandi itume imyambarire n imyenda isanzwe ifite drape nziza, kugumana imiterere no kwerekana imideri.Kubwibyo, spandex ni fibre yingirakamaro mugutezimbere imyenda yoroheje cyane.
2.Politrimethylene terephthalate fibre
Polytrimethylene terephthalate fibre (fibre ya PTT muri make) nigicuruzwa gishya mumuryango wa polyester.Nibya fibre polyester kandi nibicuruzwa bisanzwe bya polyester PET.Fibre ya PTT ifite ibintu byombi biranga polyester na nylon, ukuboko kworoshye, gukira neza kwa elastique, byoroshye gusiga irangi munsi yumuvuduko usanzwe, ibara ryiza, guhagarara neza kumyenda, bikwiranye numurima wimyenda.Fibre ya PTT irashobora kuvangwa, kugoreka no guhuzwa na fibre naturel cyangwa fibre synthique nkubwoya nipamba, kandi irashobora gukoreshwa mubitambara biboheye hamwe nigitambara.Mubyongeyeho, fibre ya PTT irashobora kandi gukoreshwa mubitambaro byinganda nizindi nzego, nko gukora amatapi, imitako, imbuga za interineti nibindi.Fibre ya PTT ifite ibyiza byimyenda ya elastike ya spandex, kandi igiciro kiri munsi yicyiza cya spandex.Ni fibre nshya itanga icyizere.
3.T-400 fibre
T-400 fibre ni ubwoko bushya bwibikoresho bya fibre fibre yakozwe na DuPont kugirango igabanye fibre ya spandex mugukoresha imyenda.T-400 ntabwo ari iyumuryango wa spandex.Irazunguruka kuruhande rwa polymers ebyiri, PTT na PET, hamwe nibiciro bitandukanye byo kugabanuka.Nibice byuruhande rumwe.Ikemura ibibazo byinshi bya spandex nko gusiga irangi bigoye, elastique irenze, kuboha bigoye, ingano yimyenda idahindagurika hamwe no gusaza kwa spandex mugihe cyo kuyikoresha.
Imyenda ikozwe muri yo ifite ibintu bikurikira:
(1) Elastique iroroshye, yoroshye kandi iramba;(2) Umwenda uroroshye, urakomeye kandi ufite drape nziza;(3) Ubuso bw'igitambara buringaniye kandi bufite imiti irwanya iminkanyari;(4) Kwinjiza ubuhehere no gukama vuba, kumva neza amaboko;(5) Iterambere ryiza kandi ryoroshye kubyitwaramo.
T-400 irashobora kuvangwa na fibre naturel hamwe na fibre yakozwe nabantu kugirango itezimbere imbaraga nubwitonzi, isura yimyenda ivanze irasukuye kandi yoroshye, urutonde rwimyenda irasobanutse, imyenda irashobora gukomeza kumera neza nyuma yo gukaraba inshuro nyinshi, imyenda ifite amabara meza yihuta, ntabwo byoroshye gucika, kumara igihe kirekire Yambaye nkibishya.Kugeza ubu, T-400 ikoreshwa cyane mu ipantaro, denim, imyenda ya siporo, imyenda y'abagore bo mu rwego rwo hejuru ndetse no mu zindi nzego kubera imikorere myiza yo kwambara.
Uburyo bwo gutwika ni ukumenya ubwoko bwa fibre ukoresheje itandukaniro ryimiterere yimiti ya fibre zitandukanye nibitandukaniro mubiranga gutwikwa byakozwe.Uburyo nugufata agace gato ka fibre ntangarugero hanyuma ukayitwika mumuriro, ukitondera witonze ibiranga gutwika fibre nuburyo, ibara, ubworoherane nubukomezi bwibisigisigi, kandi icyarimwe uhumura umunuko wabyo.
