Application
Efficient Pulp Dewatering
Reliable dewatering belts for pulp production. Designed for high tensile strength and excellent filtration to ensure high-quality pulp consistency and lower energy costs.
The Challenge
Application Context
Paper grade, machine speed, width, and drainage configuration all affect clothing selection. The challenge is balancing runnability, sheet quality, and service life.
The Solution
How PAPTEX Supports
We provide a complete fabric portfolio optimized for specific paper grades — from forming and press fabrics to dryer fabrics and dewatering belts. Each is tailored to the specific drainage, retention, and surface quality requirements of the target paper grade.

Forming Fabric
Double Layer Forming Fabric
PAPTEX Double Layer Forming Fabric strikes the ideal balance between performance and cost-effectiveness for medium-speed paper machines. The dual-layer construction features a fine paper-side warp for excellent fiber retention and sheet smoothness, supported by a coarser wear-side for durability. Designed for packaging, kraft, corrugated, and duplex board grades at speeds of 600–1,200 m/min, this fabric delivers consistent drainage uniformity across the full machine width. The optimized weave pattern provides 400–700 CFM air permeability with ≥60 kN/m MD tensile strength — more than sufficient for standard fourdrinier and top-former configurations. For mills seeking to upgrade from single-layer fabrics without the investment of full SSB technology, Double Layer fabric offers a compelling step up in formation quality, fiber retention, and service life at a moderate price point.

Dewatering Belt
Sludge Dewatering Belt
PAPTEX Sludge Dewatering Belt is a heavy-duty industrial fabric engineered for municipal and industrial wastewater treatment applications. The robust double-layer polyester/polyamide composite construction provides the high tensile strength (≥100 kN/m) and wide open area (800–1,500 CFM) needed for continuous sludge dewatering operations. The engineered void volume handles large sludge throughput with rapid, efficient water drainage while resisting blinding from fine particles. Chemical resistance across pH 3–11 ensures reliable operation with varied sludge chemistries, including lime-conditioned, polymer-conditioned, and mixed industrial sludges. Compatible with all major belt filter press brands — Andritz, Bellmer, Alfa Laval, Huber, and others — each belt is custom-fabricated to your exact machine dimensions with your choice of seam configuration.

Frequently Asked Questions
How do I choose the right fabric for my paper machine?
Selection depends on your paper grade, machine speed, machine type, and performance goals. Our engineers analyze your specific parameters — including headbox design, dewatering element configuration, and current fabric performance — to recommend the matching solution.
Can fabrics be used across different paper grades?
While some fabrics can be used across similar grades, optimization is recommended per grade. Different grades (tissue vs. kraft vs. fine paper) have very different requirements for drainage, retention, and surface quality.
How long does fabric installation take?
Forming fabric change typically takes 4-8 hours depending on machine width and complexity. Dryer fabric change is faster (2-4 hours). We provide installation supervision to minimize downtime.
