ABSTRACT:
A woven fabric having a textured, multicolor appearance is disclosed. The fabric is formed from a weave of expansible threads, wherein each thread comprises a core yarn, a first plastisol coating surrounding the core yarn, and a second plastisol coating surrounding the first coating and eccentric thereto. The first and second coatings are of different colors. The expansible threads are woven into a substantially planar fabric and then fused by heat activation. At the fusion temperature, the melt viscosity of the second coating is sufficiently high so that the first coating emerges through the second coating at the thin areas of the second coating. Preferably, the first coating has a substantially greater amount of blowing, or foaming, agent than the second coating so that the first coating expands to a greater degree than does the second coating.
