<p>A papermakers fabric woven in accordance with a preselected weave pattern. The fabric has a top surface, a bottom surface, and a center plane interposed between the top and bottom surfaces. The fabric is woven using high melting point or high degradation temperature synthetic warp yarns and similarly high melting point or high degradation temperature synthetic top and bottom weft yarns. The weft yarns in the center plane are lower melting point synthetic yarns. During heat stabilization, the fabric is exposed to sufficient heat to cause the low melting point stuffer yarns to melt and flow, and to reform in such a way that they fill to a desired extent the voids in the weave pattern where they have been inserted, thus, reducing permeability. The flow of the molten synthetic stuffer pick around and between the unmelted warp and weft yarns bonds the whole structure together, thereby improving fabric stability. Finally, because the melted stuffer pick acts as a monofilament yarn, the fabric tends to run cleaner.</p> |
