Abstract
Abstract A fabric for use in the manufacture of rubberized composite sheeting suitable for use as printing blankets, is composed of a rigid warp knitted structure of fine man-made filament yarns A, an inlaid warp of smooth, coarse man-made filament yarns B and C, and a weft insertion of coarse textured man-made filament yarns D. The warp inlay and weft insertion do not interlace, so that a very flat and smooth surfaced fabric is achieved. The fabric may be rubberized by conventional techniques.

Claim 1
Independent Claim
96 words
A printers blanket comprising: a rigid warp knitted fabric composed of relatively fine yarn of continuous man-made filaments, closely spaced and relatively coarse inlaid warp yarns and closely spaced and relatively coarse and textured weft insertion yarns, the inlaid and insertion yarns being also composed of continuous man-made filaments and extending through the knitted structure without interlacing with one another, whereby one face of the fabric is substantially constituted by the inlaid warp and a layer of vulcanized rubber coated on said one face of said knit fabric to provide a smooth surface on said face.
Claim 2
