Abstract
A process for producing a colored nonwoven fabric that contains a colorant and nanofibers, which includes the step of injecting a polymer compound A by an electrospinning method to deposit the nanofibers on a surface of a collector, in which the surface of the collector on which the nanofibers are deposited is at least partially formed into an uneven shape.
Claims16
A process for producing a colored nonwoven fabric that comprises a colorant and nanofibers, the process comprising:
- photographing and analyzing a skin portion to which the colored nonwoven fabric is to be attached;
- creating an at least partially textured surface of a collector based on the results of the photographing and analyzing;
- and
- injecting a polymer compound A by a resin melt-type electrospinning method in which a solid resin is heated and melted to produce a molten resin, and the molten resin is physically forced while a voltage is applied between the resin and the collector to deposit the nanofibers on the at least partially textured surface of the collector,
- wherein the at least partially textured surface imitates a surface configuration of a skin.
