Abstract
A secondary carpet backing for adherence to the underside of a carpet material via an adhesive. The secondary carpet backing comprises a weft inserted knit material having a series of warp yarns forming spaced rows of warp-wise extending chain stitches, and a series of weft yarns forming spaced rows extending transversely of the series of warp yarns. The weft yarns are laid in the chain stitches and serve to interconnect adjacent rows of the warp yarns. The warp yarns have a denier in the range of 300-700 and the weft yarns have a denier in the range of 1300-2300. Such a secondary carpet backing exhibits improved adhesion characteristics when adhered to the underside of a carpet material with a conventional adhesive.
