A sheet of paper begins in the forming section, where a mixture of 99% water and 1% cellulose fiber is introduced evenly across a forming fabric, which acts as both a sheet conveyor and a dewatering device. It is here that the paper sheet is formed and the initial water removal occurs. As the fabric moves, water drains through it, while the fibers and fillers that form the sheet remain on top. Today, forming fabrics have an average operating life of 45 to 60 days. Multilayer technology offered by Maanshan Sinostar is the standard today on world-class high-speed machines.
Paper machine forming fabrics are designed to retain as much fiber and other furnish components as possible while allowing water to drain through them as quickly as possible. These fabrics are typically produced from monofilament strands or yarns that are woven together in a pattern that can be classified by their fabric style (or weave);mesh, count, and diameter; surface topography; and air permeability. This module discusses how each of these characteristics affect final sheet quality. |
