Polyester Pulp Wash Fabric

The Polyester Pulp Washing Mesh Fabric is a critical filtration medium designed specifically for the recycling stream in paper making. It’s core function is to efficiently remove impurities—such as ink particles, adhesives, and fine debris—from recycled waste paper pulp, serving as a key purification stage that replaces or supplements virgin wood pulp processing. Performance is judged by its ability to balance fast dewatering, a high fiber retention rate, and thorough contaminant removal, directly impacting the quality of the recycled pulp and the economic efficiency of the production line.

Polyester pulp washing fabric is engineered as the primary filtration medium for core pulp processing equipment. It is integral to horizontal belt washers, vacuum washers, and rotary drum vacuum washers. In these systems, it performs the critical dual function of washing and thickening pulp by efficiently removing spent cooking liquors (like black liquor), washing chemicals, and dissolved solids during the bleaching and purification stages. Its fast dewatering and high retention capabilities are essential for achieving optimal pulp cleanliness and chemical recovery efficiency.
