Isesengura ryibibazo bitoroshye mugusiga Fibre ya Spandex

Birazwi neza ko fibre ya spandex ishobora gusiga irangi irangi irangi, ariko kwihuta kwaya mabara yombi ni bibi.Ubushakashatsi bwinshi bwerekanye ko amarangi atagaragara kuri nylon no gukwirakwiza amarangi ya cationic ahanini adasiga ibara kuri spandex.Ibi birerekana ko amarangi yombi adakwiriye gusiga irangi?Nkako, siko bimeze.Hamwe na catalizike yubufasha bukwiye, amarangi ya reaction ya nylon arashobora gukoreshwa mugusiga irangi rya spandex, kandi kwihuta kwayo nubujyakuzimu nibyiza.Ibikurikira nisesengura rirambuye.

1. Ku isoko hari imyenda mike ya spandex isukuye, bityo irangi rya spandex ntitumenyereye.Imyenda yera ya spandex irashobora gukoreshwa ifatanije nigitambara gito cya elastike cyangwa imyenda idakomeye, ishobora kongera ubworoherane bwimyenda.Kandi iyo umwenda wa elastike urambuye cyangwa ukande, niba ibara rya fibre spandex idahuye na filament, hazabaho ikibazo cyo kumena amabara ya spandex, bisaba gusiga irangi rya spandex.

2. Kubara ibara ryoroshye rya spandex, irangi rya acide cyangwa gusasa irangi birashobora gukoreshwa mugihe cyo kwiyuhagira aside.Mugihe cyo gukoresha amarangi amwe, amarangi yatatanye afite umuvuduko mwiza kuruta amarangi acide kuri spandex, ariko amarangi atandukanye akwirakwiza afite umuvuduko utandukanye kuri spandex.Muri rusange, niba dosiye yo gusiga irangi iri munsi ya 0.5%, gusiga irangi bishobora gutangwa.

3. Spandexfiber ni fibre yo hejuru.Urebye ko gusiga irangi igihe kirekire munsi yubushyuhe bwo hejuru bizatera kunanirwa byoroshye, muri rusange irangi munsi ya 100 ℃.Ikirenzeho, spandex ntabwo irwanya alkali, kandi gusasa amarangi hamwe n amarangi ya aside birakwiriye gusiga irangi aside.Muri rusange, irangi rya spandex rikorwa mubihe bya acide hamwe na pH ya 5.

4. Amabara atandukanye, hamwe nabafasha babereye nkibikoresho, arashobora gukoreshwa mugusiga fibre spandex.Ubu bwoko bwabafasha kumasoko bwitwa spandex ibara ryamabara cyangwa spandex colorant, ikoreshwa cyane cyane mugupfa irangi ryibara rya nylon hamwe na acide irangi kuri spandex, mubisanzwe birata amphoteric ion.Ihame ryibikorwa rirakomeye nkibi bikurikira: Mugihe cya acide, amide ihuza andi matsinda muri spandex ionize, hamwe nuburyo bwiza, bushobora kugira reaction hamwe na spandex.Noneho gutunganya ibintu bikosorwa muri spandex kuko ibara rya spandex ririmo amine positif amine, irangi hamwe na spandex ibara nabyo birashobora guhuzwa.

5. Amategeko rusange yo kwihuta nyuma yo gusiga irangi rya spandex: Karaba> ibyuya (acide)> gushiramo, kandi kwihuta kwurubuga ni byiza cyane kuruta guswera byumye.
