Abstract
Abstract A composite laminated, non-distortable needlepoint canvas material comprised of a primary layer of non-elastic, open-mesh woven fabric having a uniform weave pattern of mesh apertures and a relatively thin secondary mesh-stabilizing layer of sheer non-elastic fabric material. The threads of the open-mesh primary layer are bonded to the sheer secondary layer by an interposed adhesive layer with the apertures of the primary layer being functionally free of adhesive and the threads of the primary layer are not susceptible to raveling at the edges of the composite needlepoint material. The sheer fabric secondary layer may be a non-woven, semi-transparent, random spun synthetic fiber material or a sheer closely woven fabric material. The secondary layer is bonded to the primary layer by a liquid adhesive applied to one face of the primary layer before it is compressively interfaced with the secondary layer (with the application of heat) or the secondary layer may itself have adhesive properties. Alternatively, the adhesive material may be applied between the primary and secondary layers as a thin sheer intermediate layer of non-woven, random spun thermoplastic fibers capable of softening and fusing when heated and setting as a cured adhesive when cooled.
