Abstract

The fabric of the present invention includes a pile portion comprising spun yarn tufted in alternating arrangement with bulk continuous filament yarn through a base layer. The spun yarn includes a space-dyed component and a stock-dyed component. The bulk continuous filament yarn is also space-dyed. A process and apparatus for producing the pile fabric of the present invention are also provided.

Claims

1. A pile fabric, comprising:

a tufted pile portion extending from a backing portion, said pile portion including tufts of bulk continuous filament yarn in alternating arrangement with tufts of spun yarn, said tufts of bulk continuous filament yarn including yarn space-dyed with a plurality of colors, said tufts of spun yarn comprising multi-ply spun yarn formed from a plurality of spun singles wherein at least a portion of said plurality of spun singles is space-dyed with a plurality of colors.

2. The invention as in claim 1, wherein a portion of said plurality of spun singles is stock-dyed.

3. The invention as in claim 1, wherein said multi-ply spun yarn is two-ply yarn.

4. A tufted pile fabric, comprising:

a pile portion and a backing portion, wherein said pile portion comprises a plurality of multi-ply spun yarns and bulk continuous filament yarns tufted through said backing portion, said spun yarns and said bulk continuous filament yarns being tufted through said backing portion in alternating arrangement, said bulk continuous filament yarns being space-dyed with a plurality of colors and said spun yarn having at least one space-dyed ply and one stock-dyed ply.

5. The invention as in claim 4, wherein said bulk continuous filament yarns are formed from a polymer selected from the group consisting of nylon 6 and nylon 6,6.

6. The invention as in claim 4, wherein said spun yarn is formed from a polymer selected from the group consisting of nylon 6, and nylon 6,6.
