Abstract
An iridescent effect is achieved in satin weave filling-faced fabric using sheath-core filaments wherein the core is dyed to a color that is different from that of the sheath.
Claims18
A dyed fabric having predominantly straight and parallel yarn sections on the fabric surface and in which said yarn sections consist essentially of continuous, round concentric sheath-core polymeric filaments wherein the sheath and the cord are polyester and/or polyamide and the core of each of said filaments constitutes from 15 to 30 volume percent of the filament and is dyed a color different from that of the sheath so that said yarn sections exhibit a change in color which is dependent upon a change in the angle at which the fabric is viewed.
A dyed, round, concentric sheath-core, polymeric filament wherein the sheath and the core are polyester and/or polyamide, the core constitutes from 15 to 30 volume percent of the filament and is dyed a color that is different from that of the sheath so that the filament exhibits a change in color which is dependent upon a change in an angle at which the filament is viewed.
A fabric having a surface consisting essentially of:
- straight and parallel sections of yarns of dyed, round, concentric sheath-core polymeric filaments wherein the sheath and core polymers are dyed to different colors;
- said core constituting from 15 to 30 percent by volume of said filaments and being dyed with a fluorescent dye, and said sheath having a dead-bright luster;
- said sheath and core polymers being independently selected from the group consisting of polyester and polyamide polymers;
- so that said fabric has the ability to exhibit a change in color as the angle of view and/or of the incident light is changed, with the change in color being related to the colors of the sheath and of the core.
