Ungakuvimbela Kanjani Ukuthamba Okumnyama Kwe-Sulphur Kwe-Cotton Fiber?

Amadayi esibabule asetshenziswa kakhulu ekudayiseni imicu kakotini, kanye nasezindwangu ezixutshwe ngokotini/vinyl. Ancibilikiswa ku-sodium sulfide futhi ayindlela efanelekile yemikhiqizo emnyama yemicu ye-cellulose, ikakhulukazi i-Sulphur Black 240% kanye ne-Sulphur Blue 7dyeing. Umzali wamadayi esibabule akanabo ubudlelwano nemicu, futhi isakhiwo sawo siqukethe izibopho ze-sulphur (-S-), izibopho ze-disulfide (-SS) noma izibopho ze-polysulfide (-Sx-), ezincishiswa zibe amaqembu e-sulfhydryl (-SNa) ngaphansi kwesenzo se-sodium sulfide reductant. Iba usawoti we-sodium leuco oncibilikayo emanzini. I-Leuco inobudlelwano obuhle nemicu ye-cellulose ngenxa yama-molecule amakhulu amadayi, akhiqiza amandla amakhulu e-Van der Waals kanye namandla e-hydrogen bonding ngemicu. Nakuba ububanzi bombala wamadayi esibabule bungaphelele, ikakhulukazi oluhlaza okwesibhakabhaka nomnyama, umbala awukhanyi, kodwa ukukhiqizwa kwawo kulula, intengo iphansi, inqubo yokudaya ilula, ukufanisa imibala kulula, futhi ukushesha kombala kuhle. Nokho, kufanele kuqashelwe ukuthi amanye amadayi esibabule, njengomnyama wesibabule, angabangela ukuthamba kweCotton Fiber.

Ukuthamba kwefayibha kudinga ukunakwa ngemvaI-Sulphur Emnyama 240%Idayi isetshenziselwa ukudaya. Ezinye izici zingase zandise ingozi yokuba ne-fiber fragile, njengokusetshenziswa ngokweqile kwamadayi, okungagcini nje ngokwandisa amathuba okuba ne-fragile, kodwa futhi kunciphisa ukushesha kombala futhi kwenze ukuwasha kube nzima kakhulu. Ngaphezu kwalokho, ngemva kokudaya, kufanele kugezwe ngokuphelele ukuze kuvinjelwe ukuwasha okungahlanzekile, futhi umbala ontantayo entanjeni kulula ukuwubola ube yi-sulfuric acid ngesikhathi sokugcina, okwenza i-fiber iqhekeke.

Ukuze kuncishiswe noma kuvinjelwe ukuthamba kwefayibha, izinyathelo ezilandelayo zingathathwa:

1. Nciphisa umthamo wedayi emnyama yesulfure: umthamo wedayi yombala oyinhloko ekhethekile ye-mercerizing akufanele udlule u-700 G/iphakheji.

2. Ngemva kokudaya, geza kahle ngamanzi ukuvimbela umbala ontantayo ukuthi ubole ube yi-sulfur acid ngesikhathi sokugcina.

3. Sebenzisa izinto zokwelapha ezilwa nokuthamba, njenge-urea, i-soda ash, i-sodium acetate, njll.

4. Izinga lokuthamba kwentambo ehlutshiwe ngamanzi lingaphansi kwelentambo ehlutshiwe nge-alkali.

5. Yomisa intambo edaywe ngesikhathi ukuze ugweme ukushisa kwentambo emanzi enqubweni yokufaka inqwaba, okuholela ekunciphiseni okuqukethwe kwe-anti-brittleness agent kanye nenani le-pH.
