Basics and Latest Trends of Forming Fabric（Energy saving）

Abstract

A forming fabric is an integral component in the forming section of the paper machine. It has 3 functions: ①Dewatering pulp slurry, ②Creating the sheet formation, and ③Carrying to next press section. The origins of forming fabric are very ancient, it has been used before Louis Robert from France invented the world’s first continuous paper machine in 1798. Early forming fabrics were made of metal and had been used until around 1975. Later, as paper machines have become larger and faster for the requirement of high-quality paper and increasing productivity, plastic fabrics are the main material used. Forming fabrics are one of the important components that not only determine paper quality, but also influence the operability of the next process, the demands on it are high and forming fabrics have been constantly evolving to keep up with changing trends.

In today’s world situation, the global goal, as set out including the SDGs, is to aim for sustainable development that achieves a balance between the environment, economy, and society and this has become an urgent issue that must be achieved. In Japan, the Energy Conservation Law requires the promotion of sustainable production and consumption through the efficient use of energy and the spread of energy-saving products. The pulp and paper industry are a sector that consumes a relatively large amount of energy, and active efforts are being made to reduce the environmental impact. The drive power of the forming part is estimated to be several million to several hundred million yen per year, so reducing the drive load will help reduce energy consumption.

In this session, introduce the history of forming fabrics briefly, and describe the latest lineup, the N series and eco series, and introduce a case study of reduced drive load as an example of an energy-saving product.
