Kuki Kwihuta Kwihuta Bikennye?

Gusiga irangi rikoresha cyane cyane ubushyuhe bwo hejuru hamwe numuvuduko mwinshi mugihe cyo gusiga fibre polyester.Nubwo molekile ikwirakwiza irangi ari nto, ntishobora kwemeza ko molekile zose zisize irangi zinjira muri fibre mugihe cyo gusiga irangi.Amabara amwe akwirakwiza azakomeza kwizirika kuri fibre, bikaviramo kwihuta.Ikoreshwa mugusenya molekile y'irangi itinjiye muri fibre, kunoza umuvuduko, no kunoza igicucu.

Kurangi irangi ryirangi ryimyenda ya polyester, cyane cyane mumabara yo hagati kandi yijimye, kugirango ukureho burundu amabara areremba hamwe na oligomeri asigaye hejuru yigitambara no kunoza umuvuduko wo gusiga irangi, mubisanzwe birakenewe gukora isuku yo kugabanya nyuma yo gusiga irangi.

Imyenda ivanze muri rusange yerekeza ku rudodo rukozwe mu bice bibiri cyangwa byinshi bivanze, iyi myenda rero ifite ibyiza byibi bice byombi.Kandi muguhindura ibipimo, ibintu byinshi biranga kimwe mubice bishobora kuboneka.

Kuvanga muri rusange bivuga kuvanga fibre yibanze, ni ukuvuga fibre ebyiri yibice bitandukanye bivangwa hamwe muburyo bwa fibre fibre.Kurugero: polyester-ipamba ivanze, nayo ikunze kwitwa T / C, CVC.T / R, nibindi. Iraboshywe hamwe nuruvange rwa polyester staple fibre na fibre fibre cyangwa fibre yakozwe n'abantu.Ibyiza byayo ni: ifite isura kandi ikumva imyenda yose-ipamba, igabanya fibre fibre chimique na fibre chimique yumva imyenda ya polyester, kandi ikanoza urwego.

Kunoza amabara yihuta, kubera ko umwenda wa polyester ufite ibara ryubushyuhe bwinshi, umuvuduko wamabara uruta uw'ipamba, bityo rero kwihuta kwamabara yimyenda ivanze na polyester-ipamba nayo iratera imbere ugereranije nipamba.

Ariko, kugirango wongere amabara yihuta yimyenda ya polyester-ipamba, kugabanya isuku (ibyo bita R / C) bigomba gukorwa, na nyuma yubuvuzi nyuma yo gusiga irangi ryubushyuhe no gutatana.Ibara ryiza ryihuta rishobora kugerwaho nyuma yo kugabanya no gukora isuku.

Faple fibre ivanze ituma ibiranga buri kintu kigaragara neza.Mu buryo nk'ubwo, ibindi bice bivanze nabyo birashobora gukina inyungu zabo kugirango byuzuze imikorere cyangwa ihumure cyangwa ibisabwa mubukungu.Nyamara, imyenda ivanze na polyester-ipamba iratatana kandi irangi irangi.Hagati, kubera kuvanga ipamba cyangwa fibre ya rayon, hamwe nubushyuhe bwo gusiga ntibishobora kuba hejuru yubushyuhe bwimyenda ya polyester.Nyamara, polyester-ipamba cyangwa polyester-ipamba ya rayon, munsi yo gukangurwa na hydroxide ya alkali cyangwa sodium ikomeye, bizatera imbaraga za fibre cyangwa imbaraga zo gutaburura kugabanuka cyane, kandi biragoye kugera kumiterere yibicuruzwa mumirongo ikurikira.

Uburyo bwo kwimuka bwumuriro bwo gutandukanya amarangi burashobora gusobanurwa gutya:

1. Muburyo bwo gusiga irangi ry'ubushyuhe bwo hejuru, imiterere ya fibre polyester iba irekuye, gusasa irangi ritandukana kuva hejuru ya fibre imbere mumbere ya fibre, kandi cyane cyane ikora kuri fibre polyester ukoresheje hydrogène, gukurura dipole na van der Imbaraga.

2. Iyo fibre irangi ikozwe nubushyuhe bwo hejuru, ingufu zumuriro zitanga imbaraga zumurimo mwinshi kumurongo muremure wa polyester, ibyo bikaba byongera imbaraga zo kunyeganyega kwurunigi rwa molekile, kandi microstructure ya fibre irongera ikaruhuka, bikavamo guhuza hagati amarangi amwe amarangi hamwe na polyester ndende Urunigi.Kubwibyo, amarangi amarangi amwe afite imbaraga zo gukora cyane kandi urwego rwo hejuru rwubwigenge rwimuka ruva imbere muri fibre rugana kuri fibre yububiko bwa fibre ifite imiterere isa naho idahwitse, ihuza hamwe na fibre kugirango ikore irangi ryubutaka.

3. Mugihe cyo kwihuta kwinshi.Irangi ryo hejuru ridafunze neza, hamwe n irangi ryiziritse kumpamba ifatanye, bizahita bisiga fibre kugirango byinjire mubisubizo kandi byanduze umwenda wera;cyangwa kwizirika ku buryo butaziguye umwenda wera ukoresheje guswera, bityo ukerekana umuvuduko utose hamwe no guteranya ibicuruzwa bisize irangi umuvuduko ugabanuka.
