odayi besulfure basetshenziselwa ikakhulukazi ukudaya imicu kakotini, kanye nezindwangu ezixutshwe ukotini/vinylon. Incibilika ku-sodium sulfide futhi iyinketho ekahle emikhiqizweni emnyama yezintambo ze-cellulose, ikakhulukazi i-Sulfur Black 240% kanye ne-Sulfur Blue 7dyeing. Umzali wodayi besulfure akanakuhambisana nemicu, futhi ukwakheka kwawo kuqukethe amabhondi esibabule (-S-), amabhondi e-disulfide (-SS) noma amabhondi e-polysulfide (-Sx-), ancishiswa abe amaqembu e-sulfhydryl (-SNa) ngaphansi isenzo se-sodium sulfide reductant.Iba usawoti we-leuco sodium oncibilikayo. I-Leuco inobudlelwane obuhle bemicu ye-cellulose ngenxa yama-molecule amakhulu odayi, akhiqiza ama-Van der Waals amakhulu kanye namandla okuhlanganiswa kwe-hydrogen anemicu. Nakuba i-spectrum yombala we-sulfur dyes ingaphelele, ikakhulukazi eluhlaza okwesibhakabhaka nomnyama, umbala awukhanyi, kodwa ukukhiqizwa kwawo kulula, intengo iphansi, inqubo yokudaya ilula, ukufanisa umbala kulula, futhi ukusheshisa kombala kuhle. .Kodwa-ke, kufanele kuqashelwe ukuthi odayi abathile besulfure, abafana nomnyama wesulfure, bangase babangele ithenda ye-Cotton Fiber.
Ithenda ye-fiber idinga ukunakwa ngemuva kwe-I-Sulfur Black 240%udayi usetshenziselwa ukudaya. Ezinye izici zingase zandise ingozi ye-fiber brittleness, njengokusebenzisa ngokweqile odayi, okungagcini nje ngokukhulisa amathuba okuba brittleness, kodwa futhi kunciphisa ukushesha kombala futhi kwenza ukuwasha kube nzima nakakhulu. Ngaphezu kwalokho, ngemva kokudaya, kufanele igezwe ngokugcwele ukuze kuvinjelwe ukugeza okungahlanzekile, futhi umbala ontantayo entanjeni kulula ukubola ube yi-sulfuric acid ngesikhathi sokugcinwa, okwenza i-fiber brittle.
Ukunciphisa noma ukuvimbela ithenda ye-fiber, izinyathelo ezilandelayo zingathathwa:
1. Nciphisa umthamo wodayi omnyama wesulfure: umthamo wedayi yombala okhethekile oyi-mercerizing akumele udlule u-700 G/iphakheji.
2. Ngemva kokudaya, geza kahle ngamanzi ukuze uvimbele umbala ontantayo ukuba ungaboli ube yi-sulphur acid ngesikhathi ugcinwa.
3. Sebenzisa ama-anti-tender treatment agents, afana ne-urea, i-soda ash, i-sodium acetate, njll.
4. Izinga lethenda lentambo ekhulwe ngamanzi lincane kunalelo lentambo esulwe nge-alkali.
5. Sula intambo edayiwe kusenesikhathi ukuze ugweme ukushisisa kwentambo emanzi enqubweni yokunqwabelanisa, okuholela ekuncipheni kokuqukethwe kwe-ejenti elwa nokubola kanye nenani le-pH.
