Abstract
Outer plies of cellulosic tissue and an intermediate, Isotropic, reinforcing textile length fiber web are attached together by a pattern of adhesive lines with the fibers of the web embedded in the adhesive lines, to provide a tissue fiber laminate nonwoven fabric which is flexible and conformable with adequate strength particularly in the cross direction so as to be suitable for use as a textile substitute. The process for manufacturing this nonwoven fabric in a single pass involves printing the adehsive on one web of cellulosic tissue in a clearly defined fine line pattern, laying the fiber web on the adhesive bearing surface of the tissue web, juxtaposing a second cellulosic tissue web on the fiber web, and hot calendering the three layer composite so as to force the adhesive through the fiber web into the second tissue web while bonding the fibers of reinforcing web in place, the amount, viscosity and line pattern of the adhesive being such as to obtain ply attachment and a soft, flexible, conformable fabric rather than a stiff, boardy, sleazy material which can result from overbonding.
