What Are the Main Types of Dryer Fabrics Used in Paper Mills?

Dryer fabric is one of the key consumables in the dryer section of a paper machine. It carries the paper sheet through high-temperature drying zones, provides stable support, ensures air permeability, and directly affects drying efficiency, paper quality and running performance.

According to structure and filament shape, dryer fabrics used in paper mills are mainly divided into three types: round wire dryer fabric, flat wire dryer fabric, and spiral loop dryer fabric.

1. Round Wire Dryer Fabric

-- Round wire dryer fabric are woven with round cross-section polyester yarns.

-- The surface is smooth and uniform, with good support for the paper sheet.

-- Excellent air permeability, helping moisture escape quickly during the drying process.

-- Good stability and wear resistance, suitable for medium-speed paper machines.

-- Produces less paper marking and is widely used for cultural paper, packaging paper and general paper grades.

2. Flat Wire Dryer Fabric

-- Flat wire dryer fabric use flat-shaped polyester yarns to form a denser weaving structure.

-- The contact area with the paper sheet is larger, reducing fabric marks.

-- Higher strength and better dimensional stability at high temperatures.

-- Good wear resistance and long service life.

-- Ideal for high-speed paper machines, linerboard, corrugated paper and high-quality printing paper.

3. Spiral Loop Dryer Fabric

-- Spiral loop dryer fabric are endless construction comprising a plurality of spiral loops of monofilament yarns.

-- Fast drainage, deformation resistant, and requires no traditional sutures.

-- Easy to clean and not easy to become clogged with impurities.

-- Commonly used in tissue paper, napkin paper, toilet paper and other grades that require high breathability and softness.

Different types of dryer fabrics have their own advantages:

-- Round wire dryer fabric provide balanced performance and good versatility.

-- Flat wire dryer fabric offer high stability and smoothness for high-speed production.

-- Spiral loop dryer fabric feature ultra-high air permeability, ideal for tissue paper.

Choosing the right dryer fabric according to paper grade, machine speed and drying conditions can effectively improve output, reduce energy consumption and extend service life.
