Ibyerekeye Gutandukanya Amabara

Uburyo bwo kwimuka bwumuriro bwo gutandukanya amarangi burashobora gusobanurwa gutya:

1. Mugihe cyo gusiga irangi ryubushyuhe bwo hejuru, imiterere ya fibre polyester iba irekuye, ikwirakwiza amarangi ikwirakwira kuva hejuru ya fibre kugeza imbere muri fibre, kandi ahanini ikora kuri fibre polyester ikoresheje imigozi ya hydrogène, gukurura dipole na van der Waals imbaraga.

2. Iyo fibre irangi ikozwe nubushyuhe bwo hejuru, ingufu zubushyuhe zituma urunigi rurerure rwa polyester hamwe nimbaraga nyinshi zikorwa, ibyo bikaba byongera ihindagurika ryurunigi rwa molekile, kandi bikorohereza microstructure ya fibre, bikaviramo gucika intege. hagati ya molekile zimwe zisize irangi n'umunyururu muremure wa polyester.Kubwibyo, molekile zimwe zisiga irangi zifite imbaraga zikora cyane hamwe nubwigenge buhanitse zimuka ziva imbere muri fibre zerekeza kumurongo wa fibre zifite imiterere isa naho idahwitse, hanyuma igahuza nubuso bwa fibre kugirango ikore irangi ryubutaka.

3. Mu kizamini cyo kwihuta kwinshi, irangi ryo hejuru rihuza intege nke hamwe n irangi ryiziritse kumpamba zifata ipamba birashobora gusiga fibre byoroshye kugirango byinjire mubisubizo kandi byanduze umwenda wera;cyangwa gusiba neza no kwizirika ku mwenda wera wipimishije, bityo ukerekana umuvuduko mwinshi hamwe nubwihuta bwibicuruzwa bisize irangi.Kwihuta gukabije biragabanuka.

Irangi ritatanye rikoreshwa cyane mubikorwa bitandukanye kandi birashobora guhuzwa hamwe no gusiga amarangi kugirango bihuze amabara mabi, nka polyester, nylon, acetate ya selile, viscose, velheti ya synthique, na chloride polyvinyl.Birashobora kandi gukoreshwa mugusiga amabara buto ya plastike na feri.Bitewe n'imiterere ya molekile, bigira ingaruka nke kuri polyester kandi byemerera gusa amabara yoroshye kunyura mumajwi yo hagati.Imiterere ya fibre polyester ifite umwobo cyangwa tebes.Iyo ashyutswe kugeza kuri 100 ° C, umwobo cyangwa umuyoboro uraguka kandi ibice by'irangi byinjira.Kwagura imyenge bigarukira ku bushyuhe bw’amazi-gusiga irangi inganda za polyester bikorwa mu bikoresho byotswa igitutu kuri 130 ° C!

Iyo gusasa amarangi bikoreshwa mugukwirakwiza ubushyuhe, ibara ryuzuye rirashobora kugerwaho.

Turi abatanga amarangi.Niba ushimishijwe nibicuruzwa byacu, nyamuneka twandikire.
