Ni ukubera iki gutatanya irangi ryihuta bikennye?

  Gusiga irangi bikubiyemo ahanini gusiga fibre polyester munsi yubushyuhe bwinshi nigitutu. Nubwo molekile yamabara yatatanye ari nto, ntidushobora kwemeza ko molekile zose zisiga irangi zinjira imbere mumibiri mugihe cyo gusiga irangi. Amabara amwe yatatanye azafatana hejuru ya fibre, atera kwihuta. Kugabanya isuku bikoreshwa mukwangiza molekile y'irangi itinjiye imbere muri fibre, kunoza amabara yihuta, nibindi bikorwa.

   Kugirango ukureho burundu amabara areremba hamwe na oligomeri isigaye hejuru yimyenda ya polyester, cyane cyane mugusiga irangi ryijimye kandi ryijimye, no kunoza irangi ryirangi, isuku yo kugabanya irasabwa nyuma yo gusiga irangi. Imyenda ivanze muri rusange yerekeza ku budodo bukozwe mu ruvange rw'ibice bibiri cyangwa byinshi, bityo bikagira ibyiza by'ibi bice byombi. Byongeye kandi, ibintu byinshi biranga igice kimwe birashobora kuboneka muguhindura igipimo cyacyo.

   Kuvanga muri rusange bivuga kuvanga fibre ngufi, aho ubwoko bubiri bwa fibre hamwe nibintu bitandukanye bivangwa hamwe muburyo bwa fibre ngufi. Kurugero, ipamba ya polyester ivanze, izwi kandi nka T / C, CVC.T / R, nibindi. Yakozwe mubivange bya polyester staple fibre na pamba cyangwa fibre synthique. Ifite ibyiza byo kugira isura no kumva imyenda yose yipamba, guca intege fibre fibre lisiti na fibre chimique yumva imyenda ya polyester, no kuzamura urwego.

   Kunoza amabara yihuta. Bitewe n'ubushyuhe bwo hejuru bwo gusiga irangi ryimyenda ya polyester, kwihuta kwamabara gusumba ay'ipamba yose. Kubwibyo, ibara ryihuta ryimyenda ya polyester ivanze nayo iratera imbere ugereranije nipamba yose. Nyamara, kugirango wongere amabara yihuta yimyenda ya polyester, birakenewe ko hakorwa isuku yo kugabanuka (bizwi kandi nka R / C), hanyuma hagakurikiraho kuvurwa nyuma yo gusiga irangi ryubushyuhe bwinshi no gutatana. Gusa nyuma yo gukora isuku yo kugabanya irashobora kugerwaho kwihuta kwamabara.

   Kuvanga fibre ngufi ituma ibiranga buri kintu gikoreshwa neza. Mu buryo nk'ubwo, kuvanga ibindi bice birashobora kandi gukoresha inyungu zabo kugirango bihuze bimwe mubikorwa, ihumure, cyangwa ubukungu busabwa. Nyamara, mu bushyuhe bwo hejuru bwo gusiga irangi rya polyester ipamba ivanze, kubera kuvanga ipamba cyangwa fibre ya rayon, ubushyuhe bwo gusiga ntibushobora kuba hejuru yubw'imyenda ya polyester. Nyamara, iyo ipamba ya polyester cyangwa polyester ipamba ya fibre artificiel iterwa na alkali ikomeye cyangwa ifu yubwishingizi, bizatera kugabanuka gukomeye kwingufu za fibre cyangwa imbaraga zo kurira, kandi biragoye kugera kubuziranenge bwibicuruzwa mubyiciro bizakurikiraho.
