Hobaneng ha The Dispersion Fastness e Fosahetse?

Ho daea ka ho qhala haholo-holo ho sebelisa mocheso o phahameng le khatello e phahameng ha u daea likhoele tsa polyester.Le hoja limolek'hule tsa dae tse qhalakaneng li le nyenyane, e ke ke ea tiisa hore limolek'hule tsohle tsa dae li kena fiber nakong ea ho daea.Lidae tse ling tse qhalakantsoeng li tla khomarela bokaholimo ba fiber, e leng se bakang ho potlaka ho fokolang.E sebelisetsoa ho senya limolek'hule tsa dae tse sa kang tsa kena fiber, ho ntlafatsa ho potlaka, le ho ntlafatsa moriti.

Hasanya dae ea masela a polyester, haholo-holo ka mebala e bohareng le e lefifi, e le hore ho tlosoe ka botlalo mebala e phaphametseng le li-oligomers tse setseng holim'a lesela le ho ntlafatsa ho potlaka ha ho daea, hangata hoa hlokahala ho etsa tlhoekiso ea phokotso kamora ho daea.

Lesela le kopantsoeng ka kakaretso le bolela khoele e entsoeng ka likarolo tse peli kapa ho feta tse kopantsoeng, kahoo lesela lena le na le melemo ea likarolo tsena tse peli.'Me ka ho fetola karo-karolelano ea likarolo, litšobotsi tse ngata tsa e' ngoe ea likarolo li ka fumanoa.

Ho kopanya ka kakaretso ho bolela ho kopanngoa ha fiber e tloaelehileng, ke hore, likhoele tse peli tsa likarolo tse fapaneng li kopantsoe hammoho ka mokhoa oa li-staple fibers.Ka mohlala: lesela le kopantsoeng la polyester-cotton, leo hangata le bitsoang T / C, CVC.T/R, joalo-joalo E lohiloe ka motsoako oa fiber ea polyester e tloaelehileng le fiber ea k'hothone kapa fiber e entsoeng ke motho.Melemo ea eona ke: e na le ponahalo le maikutlo a lesela la k'hothone, e fokolisa khanya ea lik'hemik'hale le fiber ea lik'hemik'hale ea lesela la polyester, 'me e ntlafatsa boemo.

E ntlafalitse ho potlakisa 'mala, hobane lesela la polyester le mebala ka mocheso o phahameng, ho potlaka ha mebala ho phahame ho feta k'hothone, kahoo ho potlaka ha 'mala oa lesela le kopantsoeng la polyester-cotton le lona le ntlafatsoa ha le bapisoa le k'hothone.

Leha ho le joalo, ho ntlafatsa ho potlaka ha 'mala oa masela a polyester-cotton, ho hloekisa ho fokotsa (seo ho thoeng ke R / C) ho tlameha ho etsoa, ​​le ka mor'a phekolo ka mor'a ho daea le ho hasana ha mocheso o phahameng.Mokhoa o motle oa ho potlakisa 'mala o ka finyelloa feela ka mor'a ho fokotsa le ho hloekisa.

Ho kopanya li-fiber tse tloaelehileng ho lumella litšobotsi tsa karolo ka 'ngoe hore li bontšoe ka ho lekana.Ka mokhoa o ts'oanang, ho kopanya likarolo tse ling ho ka bapala melemo ea bona ho fihlela litlhoko tse ling tsa ts'ebetso kapa boiketlo kapa moruo.Leha ho le joalo, masela a kopantsoeng a polyester-cotton a qhalakanngoa le ho dauoa ka mocheso o phahameng.Bohareng, ka lebaka la ho kopanngoa ha k'hothone kapa fiber ea rayon, 'me mocheso oa ho daea o ke ke oa phahama ho feta mocheso oa lesela la polyester.Leha ho le joalo, masela a rayon a polyester-cotton kapa polyester-cotton, tlas'a ts'usumetso ea alkali e matla kapa sodium hydroxide, e tla etsa hore matla a fiber kapa matla a tabohang a theohe haholo, 'me ho thata ho finyella boleng ba sehlahisoa lihokelong tse latelang.

Ts'ebetso ea ho falla ha mocheso oa lidae tse hasaneng e ka hlalosoa ka tsela e latelang:

1. Ts'ebetsong ea ho daea mocheso o phahameng, sebopeho sa fiber ea polyester ea hlepha, dae e qhalaneng e fapana ho tloha holim'a fiber ho ea ka hare ho fiber, 'me haholo-holo e sebetsa holim'a fiber ea polyester ka hydrogen bond, dipole attraction le van der. Matla a matla.

2. Ha fiber e dailoeng e le tlas'a phekolo ea mocheso o phahameng oa mocheso, matla a mocheso a fana ka matla a phahameng a ts'ebetso ho ketane e telele ea polyester, e matlafatsang ho sisinyeha ha ketane ea molek'hule, 'me microstructure ea fiber e phutholoha hape, e leng se etsang hore ho be le tlamahano pakeng tsa 2. limolek'hule tse ling tsa dae le ketane e telele ea polyester ea fokola.Ka hona, limolek'hule tse ling tsa dae tse nang le matla a ts'ebetso e phahameng le boemo bo phahameng ba boikemelo li falla ho tloha ka hare ho fiber ho ea ho lera la fiber ka sebopeho se batlang se hlephile, li kopana le bokaholimo ba fiber ho etsa dae ea bokaholimo.

3. Nakong ea teko ea ho itima lijo ka metsi.Lidae tse ka holim'a metsi tse sa kopanngoeng ka thata, le li-dyes tse khomarelang karolo ea k'hothone e khomarelang, li tla tloha habonolo fiber ho kena ka tharollo le ho silafatsa lesela le lesoeu;kapa ho khomarela ka ho toba lesela le lesoeu la teko ka ho phunya, kahoo ho bontša ho potlaka ho metsi le ho ferekanngoa ha sehlahisoa se dailoeng ho fokotseha hoa fokotseha.
