Papermaking Mesh for Dehydrators, Polyester Formed Mesh, Washing
Pulp Dewatering Mesh Belt
Product Introduction:
Polyester forming mesh is a critical industrial textile widely used
in the papermaking, environmental protection, and non-woven fabric
industries, celebrated for its excellent mechanical properties,
chemical stability, and long service life. Crafted from
high-quality polyester filaments (typically PET, polyethylene
terephthalate), this mesh boasts outstanding resistance to
abrasion, hydrolysis, and most organic solvents—making it suitable
for long-term operation in wet, high-temperature, and chemically
active environments, a key advantage over traditional metal or
nylon meshes.
The manufacturing process of polyester forming mesh involves
precision weaving using advanced rapier or air-jet looms, followed
by heat-setting and surface treatment to enhance dimensional
stability and wear resistance. Its structure is mainly divided into
single-layer, double-layer, and multi-layer designs. Single-layer
mesh, with a simple plain or twill weave, is ideal for producing
thin papers like tissue and cultural paper, ensuring uniform water
drainage and smooth paper surface. Double-layer and multi-layer
meshes, featuring a composite structure with upper and lower layers
connected by binding wires, offer higher mechanical strength and
load-bearing capacity, making them perfect for heavy-duty
papermaking (e.g., cardboard, kraft paper) or sludge dewatering in
environmental engineering. The mesh’s key parameters—such as
aperture size (ranging from 0.1mm to 5mm), mesh count (20-200 wires
per inch), and thickness (0.3mm-5mm)—can be customized to match
specific production requirements.
In practical applications, polyester forming mesh plays an
irreplaceable role. In the papermaking industry, it acts as the
core component of the paper machine’s forming section, supporting
the fiber suspension, draining water efficiently, and shaping the
paper web while preventing fiber loss, thus improving paper quality
and production efficiency. In environmental protection, it is used
in belt filter presses and vacuum filters for sludge dewatering in
municipal sewage treatment and industrial wastewater treatment,
effectively separating solid and liquid phases with low maintenance
costs. Additionally, it finds applications in non-woven fabric
production (as a forming substrate) and food processing (for
filtering and conveying, complying with food-grade safety
standards).
Compared to alternative materials, polyester forming mesh offers
distinct benefits: it is lightweight, reducing the load on
equipment; it has low friction, minimizing energy consumption; and
it is easy to clean, reducing downtime for maintenance. With its
customizable specifications, excellent performance, and wide
application range, polyester forming mesh has become an essential
material for modern industrial production, meeting the high
standards of efficiency, durability, and environmental friendliness
required by various sectors.

Product application
Polyester mesh finds diverse applications. In papermaking, it aids
sheet formation; in sewage treatment, filters impurities. It sieves
food, separates in pharmaceuticals, and enables screen - printing,
boosting efficiency across industries.
Product advantage
The edges of the sieve are smoothed by thermal sealing, reinforced
in a width of about 4 cm with a two-component flexible adhesive.
The sieves are connected into an endless strip by a demountable
stainless steel (AISI 316) clipper joint. Another option for
connecting the sieve into an endless strip is a woven non-separable
joint, which has a longer service life than the clip joint, but can
only be used on machines that allow the installation of an endless
belt.
Filter screens are used as endless strips connected by a detachable
or non-separable joint.
The edges of the filter screens are melted and reinforced with
mechanically resistant flexible two-component adhesive. Triangular
reinforcement of the joint at the edges of the sieve increases the
mechanical resistance of the joint.
