Dryer clothes or dryer fabrics or felts have an important role in the dryer section. Synthetic dryer cloth or fabrics are also considered as conveyor belts.
紙のウェブが紙の機械のプレスセクションを超えると、その重量の半分以上が水です。紙のウェブのほとんどの水は、紙張りのドライヤーセクションで削除して、4〜6％の最終的な水分含有量を確保する必要があります。乾燥機セクションは、ペーパーマシンの最もエネルギー集約型コンポーネントの1つです（約60％）。したがって、乾燥機または画面の役割は絶対に巨大です。
乾燥機の生地は、蒸気加熱乾燥シリンダーの表面に紙のウェブを押します。その結果、ウェブの温度が上昇し、水は多孔質ドライヤースクリーンに蒸発します。さらに、ドライヤーファブリックは、ドラムから別のドラムに移動する際に、紙のWebをサポートするのに役立ちます。ドライヤー画面は、Webの収縮を制御します。
Dryer screen can be classified according to weave, category and combination method. Synthetic polyester dryer screen can be classified as one layer, one and a half layer, double layer, etc. according to the category. According to the weaving method, synthetic polyester dryer screen can be classified into 3 shuttle mouth, 4 shuttle mouth, etc. And as far as the combination method is concerned, the dryer can be divided into insert, pin, pin ring and spiral ring connection.
選択：ドライヤー画面またはフェルトの選択は、紙グレード、乾燥機の構成、乾燥機温度、フードの空気バランスなどのさまざまな紙の機械パラメーターに依存します。ドライヤースクリーンの設計と材料も非常に重要です。
For a specific paper machine; the dryer permeability, design and material should be adjusted to ensure optimal drying from the drying zone. The breathability of the dryer fabrics or felt has a significant impact on the rate of evaporation of moisture. If the permeability decreases, the dryer fabrics is less capable of drying. Dryer screens with permeability in the range of 700-1000 cfm are used on paper machines to produce higher gsm kraft and paperboard grades. On the other hand 200-400 cfm dryer fabrics are widely used on medium to high-speed paper machines and below medium to high-speed paper machines on low-speed machines. A large contact area with the drying surface ensures uniform drying. Correct selection of dryers improves paper machine operation, increases drying speed, improves paper quality and saves energy.
In addition, the dryer fabrics or felt should have the following parameters or characteristics: aerodynamic properties, heat transfer, fabric tension, sheet support, thickness, heat resistance, moisture resistance, elongation by heat should be low, durability, silent drive, easy handling, etc.
