Ungayithintela njani i-Sulphur Black Tender yeCotton Fiber?

Iidayi zesulfur zisetyenziselwa kakhulu ukudaya iifayibha zekotoni, kunye neefayibha ezixutyiweyo zekotoni/vinyl. Inyibilika kwi-sodium sulfide kwaye lukhetho olufanelekileyo kwiimveliso ezimnyama zeefayibha ze-cellulose, ngakumbi kwi-Sulphur Black 240% kunye ne-Sulphur Blue 7dyeing. Umzali weedayi ze-sulfur akanalo ulwalamano kwiifayibha, kwaye isakhiwo sawo siqulathe iibhondi ze-sulfur (-S-), iibhondi ze-disulfide (-SS) okanye iibhondi ze-polysulfide (-Sx-), ezincitshiswa zibe ngamaqela e-sulfhydryl (-SNa) phantsi kwesenzo se-sodium sulfide reductant. Iba yityuwa ye-sodium leuco enyibilikayo emanzini. I-Leuco inolwalamano oluhle kwiifayibha ze-cellulose ngenxa yeemolekyuli ezinkulu zeedayi, ezivelisa i-Van der Waals enkulu kunye ne-hydrogen bonding forces ngeefayibha. Nangona uluhlu lwemibala yedayi yesalfure lungaphelelanga, ikakhulu luhlaza okwesibhakabhaka nomnyama, umbala awukhazimli, kodwa ukwenziwa kwayo kulula, ixabiso liphantsi, inkqubo yokudaya ilula, ukufanisa imibala kulula, kwaye ukukhawuleza kombala kulungile. Nangona kunjalo, kufuneka kuqatshelwe ukuba ezinye iidayi zesalfure, ezifana nomnyama wesalfure, zinokubangela ukuthamba kweCotton Fiber.

Ukuthamba kwefayibha kufuneka kuqwalaselwe emva kokubaI-Sulphur Emnyama 240%Idayi isetyenziselwa ukudaya. Ezinye izinto zinokwandisa umngcipheko wokuba ifayibha ibuthathaka, njengokusetyenziswa kakhulu kwedayi, okungagcini nje ngokwandisa amathuba okuba ibuthathaka, kodwa kunciphisa nokuba umbala ukhawuleze kangakanani kwaye kwenze kube nzima ukuhlamba. Ukongeza, emva kokudaya, kufuneka ihlanjwe ngokupheleleyo ukuze kuthintelwe ukuhlanjwa okungacocekanga, kwaye umbala odadayo kwintambo kulula ukuwubola ube yi-sulfuric acid ngexesha lokugcina, nto leyo eyenza ifayibha ibuthathaka.

Ukuze kuncitshiswe okanye kuthintelwe ukuthamba kwefayibha, kunokwenziwa la manyathelo alandelayo:

1. Umlinganiselo womthamo wedayi emnyama yesalfure: umthamo wedayi yombala oyintloko we-mercerizing awuyi kudlula i-700 G/iphakheji.

2. Emva kokuyidaya, hlamba kakuhle ngamanzi ukuze umbala odadayo ungaboli ube yi-sulfur acid ngexesha lokugcinwa.

3. Sebenzisa izinto zonyango ezithintela ukuthamba, ezifana ne-urea, i-soda ash, i-sodium acetate, njl.

4. Ubungakanani bokuthamba koboya obukhutshiweyo ngamanzi bungaphantsi kobo boya obukhutshiweyo obukwi-alkali.

5. Yomisa intambo edayiweyo ngexesha elifanelekileyo ukuze ungafudunyezwa yintambo emanzi kwinkqubo yokufaka izinto ezifunekayo, nto leyo ekhokelela ekunciphiseni umxholo we-anti-brittleness agent kunye nexabiso le-pH.
