Abstract

The present invention provides a solution to the prior art problem of producing a high density papermakers batt fabric or felt which may be secured to an undamaged under layer in an economic manner. The present invention provides these improvements by providing a batt which is comprised of a non-­ woven low melt scrim to which the batt material is initially needed. Subsequent to producing a batt of the required density, the batt may, if desired, be needled or adhered to an under layer fabric. The completed felt will be subjected a heat pressing operation which will elevate the temperature of the batt to a temperature above the softening temperature of the scrim but below the melting point of the batt fibers. In this manner, the batt and under layer fabric are unified to produce a multilayer papermakers felt with minimum effort and disruption of the under layer.
