Abstract
A papermaker's fabric is provided having a spun bonded reinforcement. A layer of spun bonded material may be placed in any one of a number of possible locations in the fabric, depending upon the felt stratification desired. For example, it may be attached to the upper surface (or paper contacting side) of the base fabric layer; to the lower surface (or machine contacting side) of the base fabric layer; between two base fabric layers, in the case of a laminated felt; between layers of fibers; or in any other desired location. The spun bonded material may be attached through the use of needling or by use of adhesives, low melts, or ultrasonic methods.
