Mayelana ne-Disperse Dyes

Inqubo yokufuduka okushisayo kodayi abahlakazayo ingachazwa kanje:

1. Ngesikhathi senqubo yokudaya izinga lokushisa eliphezulu, ukwakheka kwe-polyester fibre kuyaxega, odayi abahlakazekile basakazeke ukusuka ebusweni bomucu ukuya ngaphakathi kwefayibha, futhi ikakhulukazi basebenza ku-polyester fiber nge-hydrogen bond, i-dipole attraction kanye ne-van der Waals. amandla.

2. Uma i-fiber edayiwe ingaphansi kokwelashwa kokushisa okuphezulu, amandla okushisa enza iketango elide le-polyester elinamandla okusebenza aphezulu, aqinisa ukudlidliza kweketango lamangqamuzana, futhi axegise ukwakheka kwe-microstructure yefayibha, okuholela ekubeni buthaka kwamabhondi. phakathi kwama-molecule athile kadayi kanye neketango elide le-polyester.Ngakho-ke, amanye ama-molecule kadayi anamandla asebenzayo aphezulu kanye nokuzimela okuphezulu asuka ngaphakathi kwefayibha aye ongqimbeni olungaphezulu lwefayibha enesakhiwo esixege kakhulu, futhi ahlanganiswe nengaphezulu lefayibha ukuze akhe udayi wogqinsi olungaphezulu.

3. Esivivinyweni sokushesha okumanzi, odayi bangaphezulu abanesibopho esibuthakathaka kanye nodayi abanamathela engxenyeni enamathelayo kakotini bangashiya kalula i-fiber ukuze bafake isixazululo futhi bangcolise indwangu emhlophe;noma hlikihla ngokuqondile futhi unamathele endwangu emhlophe yokuhlola, ngaleyo ndlela ubonise ukushesha okumanzi nokushesha okumanzi komkhiqizo odayiwe.Ukushesha ukuhlikihla kuyancipha.

Odayi be-Disperse basetshenziswa kakhulu ezinqubweni ezihlukahlukene futhi bangahlanganiswa nodayi abahlakazayo ukuze kuhlanganiswe imibala engemihle, njenge-polyester, inayiloni, i-cellulose acetate, i-viscose, i-velvet yokwenziwa, ne-polyvinyl chloride.Zingasetshenziswa futhi ukufaka umbala izinkinobho zepulasitiki nezinsimbi.Ngenxa yesakhiwo samangqamuzana, anomphumela obuthakathaka ku-polyester futhi avumela kuphela imibala ethambile ukuba idlule kumathoni aphakathi.Isakhiwo semicu ye-polyester sinezimbobo noma amashubhu.Uma kushisa ku-100 ° C, imbobo noma ithubhu iyakhula futhi izinhlayiya zikadayi zingena.Ukwandiswa kwama-pores kunqunyelwe ukushisa kwamanzi-imboni yokudaya i-polyester yenziwa emshinini ocindezelwe ku-130 ° C!

Lapho ama-dyes ahlakazekayo asetshenziselwa ukudluliswa okushisayo, umbala ogcwele ungafinyelelwa.

Singabahlinzeki be-Disperse Dyes.Uma unentshisekelo ngemikhiqizo yethu, sicela ukhululeke ukuxhumana nathi.
