In the fast-paced world of high-speed paper production, retention isn't just a metric—it's a cornerstone of efficiency. Poor retention results in lost fillers and fines, escalating chemical costs, inconsistent sheet quality, and ultimately, reduced mill profitability. For fabric manufacturers, the challenge lies in designing forming fabrics that enhance retention while maintaining optimal drainage and formation. This guide delves into the critical design elements—caliper, voi

In demanding dryer sections, hydrolysis weakens yarn integrity under high heat and humidity, shortening fabric life and raising costs. Hot pockets (>150°C) intensify this risk, requiring materials that balance durability with performance. This article compares PET vs. PPS yarns and key monitoring practices to limit thermal breakdown.   1. PET Yarns: Enhancing Standard Durability: Polyester (PET) yarns offer cost-effective permeability for most dryer applications but degrade

Dryer fabrics have evolved significantly over the past five years, with innovations targeting heat-resistance, cleanability, single-layer performance, and new constructions that improve drying efficiency and runnability on fast machines. These advances reduce energy use, limit seam/marking defects, and extend fabric life — critical for both paper makers and fabric manufacturers. As part of PMC Centre’s weekly series, here is a concise, fact-based overview of the latest develo

In today's high-speed paper machines processing high-fines and recycled furnishes, the dryer section remains a critical bottleneck for efficiency and profitability. Woven and spiral dryer fabrics each offer unique advantages—such as stability and permeability—but mismatching them to machine positions, heat loads, or contaminants can lead to sheet defects, elevated energy use, and frequent downtime. Drawing from recent industry insights, this post outlines the top pain points

In the high-stakes dryer sections of paper machines, selecting and positioning the right fabric—woven or spiral—can significantly enhance drying efficiency, sheet quality, and operational uptime. Woven fabrics excel in controlled contact and surface finish, while spirals prioritize permeability and durability in demanding conditions. This comprehensive guide combines insights from our recent LinkedIn series to help technical teams optimize placements, drawing on proven applic

Introduction: In the forming section of paper machines, excess water carry-over represents a pervasive challenge that undermines efficiency, escalates energy consumption, and compromises sheet quality. This phenomenon occurs when forming fabrics retain or transport surplus water into subsequent sections, such as the press and dryer, leading to higher steam demands, reduced machine speeds, and increased operational costs. For paper makers, it manifests as hidden energy drains
