UThintelwa Njani Ithenda yeSulfur emnyama yeFayibha yomqhaphu?

Idayi zesulfure zisetyenziselwa ukudaya imisonto yomqhaphu, kunye nelaphu elidityanisiweyo lomqhaphu / ivinylon. Ichithwe kwi-sodium sulfide kwaye iyona khetho efanelekileyo kwiimveliso ezimnyama ze-cellulose fibers, ngokukodwa kwi-Sulfur Black 240% kunye ne-Sulfur Blue 7dyeing. Umzali wedayi zesulfure azinabudlelwane kwimicu, kwaye isakhiwo saso sinemibhobho yesulfure (-S-), iibhondi ze-disulfide (-SS) okanye iibhondi ze-polysulfide (-Sx-), ezincitshiswe kumaqela e-sulfhydryl (-SNa) phantsi isenzo se-sodium sulfide reductant.Iba yityuwa yesodium ye-leuco enyibilikayo. I-Leuco inobudlelwane obuhle bemicu ye-cellulose ngenxa yeemolekyuli ezinkulu zedayi, ezivelisa i-Van der Waals enkulu kunye ne-hydrogen bonding force ene-fibers. Nangona umbala wedayi zesulfure ungagqibekanga, ubukhulu becala oluhlaza okwesibhakabhaka nomnyama, umbala awuqaqambi, kodwa ukuveliswa kwawo kulula, ixabiso liphantsi, inkqubo yokudaya ilula, ukuhambelana kombala kulungele, kunye nokukhawuleza kombala kulungile. .Kufuneka kuqatshelwe, nangona kunjalo, ukuba iidayi ezithile zesulfure, ezifana nesulfure emnyama, zingabangela ithenda yeCotton Fiber.

Ithenda yefiber kufuneka inikwe ingqwalasela emva kweSulphur Black 240%Idayi isetyenziselwa ukudaya. Ezinye izinto zinokonyusa umngcipheko we-fiber brittleness, njengokusetyenziswa kakhulu kwedayi, enganyusi nje kuphela ithuba lokonakala, kodwa ikwanciphisa nokukhawuleza kombala kwaye kwenze ukuhlamba kube nzima ngakumbi. Ukongezelela, emva kokudaya, kufuneka ihlanjwe ngokupheleleyo ukukhusela ukuhlamba okungahlambulukanga, kwaye umbala ojikelezayo kwintambo kulula ukubola kwi-asidi ye-sulfuric ngexesha lokugcinwa, okwenza i-fiber brittle.

Ukunciphisa okanye ukuthintela ithenda yefayibha, la manyathelo alandelayo anokuthathwa:

1. Ukunciphisa umthamo wedayi emnyama yesulfure: idosi yedayi yombala okhethekileyo we-mercerizing ayisayi kudlula i-700 G/package.

2. Emva kokudaya, hlamba ngokucokisekileyo ngamanzi ukuze uthintele umbala odadayo ukuba ungaboli ube yi-asidi yesulfure ngexesha lokugcinwa.

3. Sebenzisa i-anti-tender treatment agents, ezifana ne-urea, i-soda ash, i-acetate ye-sodium, njl.

4. Iqondo lethenda lomsonto ogudiweyo wamanzi lingaphantsi kunolo lomsonto ogutyungelwe yialkali.

5. Yomisa intambo edayiweyo ngexesha ukuze ugweme ukufudumeza komsonto omanzi kwinkqubo yokupakisha, okukhokelela ekunciphiseni umxholo we-anti-brittleness agent kunye nexabiso le-pH.
