Cationic-cellulose nanofibers: Preparation and dyeability with anionic reactive dyes for apparel application

► Cationic-cellulose nanofibers have been prepared via electrospinning and post-treatment. ► Cellulose nanofibers were cationized to form cationized-cellulose nanofibers and then dyed with anionic reactive dyes. ► Cationization of cellulose nanofibers enhanced dye color yield without electrolyte addition. ► Very good color yields, colorimetric and color fastness results were achieved. ► It has opened a new door for producing fascinating nanofibers for use as regular apparel and fashion.
