Abstract:
PROBLEM TO BE SOLVED: To provide a colored nanofiber nonwoven fabric which can be well colored with little fading or change of color, without degradation of mechanical properties caused by a colorant.SOLUTION: A colored nanofiber nonwoven fabric is made from nanofiber that is a polymer compound containing carbon black as colorant. The carbon black has an average particle diameter d which is less than or equal to an average diameter D of the nanofiber constituting the nanofiber nonwoven fabric. The colorant particles are embedded in the nanofiber. The surface of the nanofiber shows an irregular shape on it, resulting from the presence of the colorant.SELECTED DRAWING: Figure 1
