Abstract—Colorful nanofibers were prepared through
electrospinning technique followed by dyeing with different
reactive dyes by comparing different dyeing techniques such as
ultrasonic as well as conventional (padding method). Excellent
color yield and color fastness were achieved through proper
optimization conditions in ultrasonic treatment. Nanofibers
exhibited smooth and bead free morphology. Two different
polymers were selected for electrospinning, i.e. cellulose acetate
and nylon-6. Preparation of cellulose nanofibers included
electrospinning of cellulose acetate following deacetylation
under alkaline conditions. Results suggested that dyes
conferred improved color yield on the basis of K/S values.
Deacetylation was also confirmed through FTIR. The resulting
nanofibers can serve better choice for advanced apparel
applications.
Index Terms—Padding, batch wise, dyed nanofibers.
