ABSTRACT:
A press fabric incorporating bicomponent material in fiber form or yarn form, the bicomponent material having a core material with a higher melting point surrounded by a covering material with a lower melting point. The bicomponent material will be present in the base fabric in yarn form and/or in the batt material in fiber form in amount ranging from 10-100%. Upon heatsetting the assembled press fabric structure, the lower melting point material of the bicomponent material becomes soft, flowing into the crossing of the batt fibers, if present in the batt material, or into the crossings of the weave pattern, if present in a base fabric, to form a matrix.
