Kutheni ukusasazwa kokudaya ngokukhawuleza kungalunganga?

  Ukusasaza ukudaya ikakhulu kubandakanya ukudaya imicu yepolyester phantsi kobushushu obuphezulu kunye noxinzelelo. Nangona iimolekyuli zedayi ezisasaziweyo zincinci, akunakuqinisekwa ukuba zonke iimolekyuli zedayi ziya kungena ngaphakathi kwimicu ngexesha lokudaya. Ezinye iidayi ezihlakaziweyo ziya kubambelela kumphezulu wemicu, zibangele ukukhawuleza okungahambi kakuhle. Ukucocwa kokunciphisa kusetyenziselwa ukonakalisa iimolekyuli zedayi ezingangenanga ngaphakathi kwimicu, ukuphucula ukukhawuleza kombala kunye neminye imisebenzi.

   Ukuze kususwe ngokupheleleyo imibala edadayo kunye nee-oligomers ezishiyekileyo kumphezulu welaphu le-polyester, ngakumbi kumbala ophakathi kunye nomnyama wokudaya, kunye nokuphucula ukudaya ngokukhawuleza, ukucocwa kokunciphisa kuyafuneka emva kokudaya. Amalaphu adityanisiweyo abhekisa kwimisonto eyenziwe ngomxube wezinto ezimbini okanye ngaphezulu, nto leyo enezinto eziluncedo kula malungu mabini. Ngaphezu koko, iimpawu ezininzi zecandelo elinye zinokufumaneka ngokulungelelanisa umlinganiselo wayo.

   Ukudibanisa ngokuqhelekileyo kubhekiselele kumxube omfutshane wefayibha, apho iindidi ezimbini zefiber ezinemicu eyahlukeneyo zixutywa kunye ngendlela yefiber emfutshane. Ngokomzekelo, i-polyester cotton blended fabric, eyaziwa ngokuba yi-T / C, i-CVC.T / R, njl. Ilukwe ukusuka kumxube we-polyester staple fibers kunye ne-cotton okanye i-synthetic fibers. Inenzuzo yokuba nenkangeleko kunye nokuziva kwayo yonke ilaphu lomqhaphu, yenza buthathaka imichiza yefiber luster kunye nekhemikhali ifayibha yokuziva yelaphu lepolyester, kunye nokuphucula inqanaba.

   Ukuphuculwa kokukhawuleza kombala. Ngenxa yobushushu obuphezulu bokudaywa kwelaphu lepolyester, ukukhawuleza kombala kuphezulu kunomqhaphu wonke. Ke ngoko, ukukhawuleza kombala welaphu elidityanisiweyo lepolyester likwaphuculwe xa kuthelekiswa nomqhaphu wonke. Nangona kunjalo, ukuphucula ukukhawuleza kombala welaphu le-polyester yekotoni, kuyimfuneko ukuhlanjululwa kokunciphisa (ekwabizwa ngokuba yi-R / C), kulandelwa kunyango emva kokushisa okuphezulu kunye nokusabalalisa. Kuphela emva kokwenza ukucocwa kokunciphisa kunokufikelela ukukhawuleza kombala ofunekayo.

   Ukudibanisa ifayibha emfutshane kwenza ukuba iimpawu zecandelo ngalinye zisetyenziswe ngokulinganayo. Ngokufanayo, ukudityaniswa kwamanye amacandelo kunokunyusa izibonelelo zawo ngokwahlukeneyo ukuhlangabezana neemfuneko ezithile ezisebenzayo, ezithuthuzelayo, okanye zoqoqosho. Nangona kunjalo, kwi-high-tempersion dispersion dyeing ye-polyester cotton blended fabrics, ngenxa yokudibanisa i-cotton okanye i-rayon fibers, iqondo lokushisa lokudaya alikwazi ukuba phezulu kunelaphu le-polyester. Nangona kunjalo, xa ilaphu le-polyester yomqhaphu okanye ilaphu le-fiber eyenziwe nge-polyester livuselelwa yi-alkali eyomeleleyo okanye umgubo we-inshurensi, iya kubangela ukuhla okukhulu kwamandla efayibha okanye ukukrazula amandla, kwaye kunzima ukufezekisa umgangatho wemveliso kwizigaba ezilandelayo.
