| 5 | Reactive Dyeing of Electrospun Cellulose Nanofibers by Pad-steam Method显示文摘Based on the functional properties of electrospun cellulose nanofibers(CNF),scientists are showing substantial interest to enhance the aesthetic properties.However,the lower color yield has remained a big challenge due to the higher surface area of nanofibers.In this study,we attempted to improve the color yield properties of CNF by the pad-steam dyeing method.Neat CNF was obtained by deacetylation of electrospun cellulose acetate(CA)nanofibers.Three different kinds of reactive dyes were used and pad-steam dyeing parameters were optimized.SEM images revealed smooth morphology with an increase in the average diameter of nanofibers.FTIR results showed no change in the chemical structure after dyeing of CNF.Color fastness results demonstrated excellent ratings for reactive dyes,which indicate good dye fixation properties and no color loss during the washing process.The results confirm that the pad-steam dyeing method can be potentially considered to improve the aesthetic properties of CNF,which can be utilized for functional garments,such as breathable raincoats and disposable face masks. | Winges FATIMA Muhammad TARIQUE LI Min CHEN Mingyi Muzamil KHATRI Muhammad Nauman SARWAR Icksoo KIM Farooq AHMED Zeeshan KHATRI CHEN Rouxi WEI Kai | 2021 | Chemical Research in Chinese Universities2021，37，3： | 0 |
