1.5-Layer Polyester Forming Fabric for Tissue Paper Hydrolysis-Resistant, High Fiber Retention

1.5-Layer Polyester Forming Fabric for Tissue Paper Hydrolysis-Resistant, High Fiber Retention

Product Description

Polyester forming fabrics are the critical dewatering and sheet-forming medium on modern paper machines. Woven from high-grade polyester monofilaments in single-layer, 1.5-layer, double-layer, 2.5-layer, and triple-layer constructions, these fabrics receive the stock from the headbox, separate water from fiber, and transport the forming web to the press section. Engineered for dimensional stability and consistent permeability, they are the mainstream choice for tissue, printing, packaging, and board grades.

Technical Specifications

Features & Benefits

Polyester forming fabrics are designed to replace traditional metal wires, offering not only reliable sheet formation but also the advantages of significantly reduced weight and easier installation. These products are available in a variety of weave patterns—including 4-shaft, 5-shaft, 8-shaft, and multi-layer designs—which can be customized to meet specific requirements regarding paper grade, machine speed, and dewatering. Whether producing high-quality printing paper or heavy-duty kraft paperboard, the choice of forming fabric structure directly influences filler retention, sheet formation quality, and the overall operational performance of the paper machine.

Applications

Polyester forming fabrics are critical components in modern papermaking machines, facilitating both dewatering and sheet formation. Woven from high-quality polyester monofilaments, these fabrics are available in various structural configurations, including single-layer, 1.5-layer, double-layer, 2.5-layer, and triple-layer designs. They receive the pulp slurry from the headbox, separate the fibers from the water, and transport the formed paper web to the press section. Thanks to their excellent dimensional stability and uniform water permeability, polyester forming fabrics have become the preferred choice for the production of a wide range of paper products, including tissue, printing paper, packaging paper, and paperboard.
