Synthetic Mesh Introduction

? What is Synthetic Filter Mesh?

Synthetic filter mesh (also known as industrial filter fabric or monofilament woven mesh) is a precision-engineered textile manufactured from continuous synthetic monofilament fibers — typically Nylon (PA), Polyester (PES/PET), or Polypropylene (PP) — woven into a screen-like structure with controlled, uniform openings.

Unlike random-fiber nonwoven media, woven synthetic mesh offers precise and repeatable pore geometry, high mechanical strength, excellent chemical resistance, and long service life. It is the preferred filtration medium for applications requiring consistent particle retention, high flow rates, and easy cleanability.

? Key Characteristics of Synthetic Filter Mesh

Precision Pore Size

Consistent opening geometry from 1 µm to 10,000 µm — every square inch is identical

High Mechanical Strength

Monofilament construction provides tensile strength exceeding 15 N in both warp and weft directions

Chemical Resistance

PA, PES, and PP grades resist acids, alkalis, oils, solvents, and biological fluids

?️

Temperature Tolerance

Service range from -40°C to 260°C depending on polymer selection

Flexible & Dimensionally Stable

Can be fabricated into bags, discs, sheets, or pleated cartridges without losing pore integrity

Easy to Clean & Reusable

Monofilament structure allows backwashing, ultrasonic cleaning, and repeated use

? Industry Applications

Fuel, oil, air intake, hydraulic, cabin air filters

Water Treatment

Municipal, industrial, desalination, wastewater filtration

Medical & Pharma

Biopsy bags, IV filters, sterile vents, syringe filters

Food & Beverage

Brewing, dairy, edible oil, juice, sugar, starch filtration

Chemical Processing

Acid, solvent, catalyst recovery, polymer melt filtration

Electronics

PCB filtration, semiconductor chemicals, EMI shielding

? Filter Mesh Specifications

Every synthetic filter mesh is defined by five key parameters. Understanding these specifications is essential for selecting the correct mesh for your application.

Thread Diameter

The thickness of each monofilament fiber, measured in micrometers (µm).

Typical range: 20 µm ~ 1,000 µm

Thicker threads → stronger mesh, lower open area
Thinner threads → finer filtration, higher flow resistance

Mesh Count

The number of openings per linear inch or centimeter — expressed as mesh/inch or mesh/cm.

Typical range: 5 ~ 700 mesh/inch

Higher mesh count → finer filtration, smaller openings
Lower mesh count → coarser filtration, higher flow rate

58%Open Area

Open Area

The percentage of the total fabric surface that consists of open space (holes), expressed as %.

Typical range: 15% ~ 75%

Higher open area → higher flow rate, less pressure drop
Lower open area → better particle retention, higher ΔP

THICKThickness

Fabric Thickness

The overall thickness of the woven fabric, measured in micrometers (µm).

Typical range: 50 µm ~ 2,000 µm

Determined by thread diameter and weave pattern
Affects mechanical strength and pleatability

g/m²Weight

Weight (Grams per m²)

The areal density of the fabric, measured in grams per square meter (g/m²).

Typical range: 20 ~ 500 g/m²

Related to thread diameter, mesh count, and material density
Higher weight = more material, stronger fabric

µmMesh Opening

Mesh Opening (Pore Size)

The distance between adjacent threads, i.e., the size of the square opening. Measured in micrometers (µm).

Typical range: 1 µm ~ 10,000 µm

Determines the maximum particle size that passes through
Formula: Opening = 25,400 ÷ mesh/inch − thread diameter

? Typical Specification Range by Material

Parameter	PA Nylon	PES Polyester	PP Polypropylene	Notes
Mesh Range (mesh/inch)	5 ~ 700	5 ~ 620	6 ~ 230	Higher = finer filtration
Thread Diameter (µm)	30 ~ 1,000	27 ~ 600	45 ~ 1,000	Thicker = stronger mesh
Mesh Opening (µm)	1 ~ 3,233	0.3 ~ 4,400	65 ~ 3,233	Determines particle cut-off
Open Area (%)	15 ~ 68%	17 ~ 77%	17 ~ 58%	Higher = lower pressure drop
Thickness (µm)	50 ~ 1,900	40 ~ 1,170	82 ~ 1,950	Affects rigidity
Weight (g/m²)	20 ~ 450	26 ~ 282	26 ~ 443	Higher = heavier fabric
Max Service Temp (°C)	120 ~ 150	150 ~ 180	80 ~ 100	Depends on grade
Chemical Resistance	Good (oils, solvents)	Good (acids, bleaches)	Excellent (acids, alkalis)	See material guide

?️ Filter Mesh Production Process

From raw material to finished product — every roll of synthetic filter mesh undergoes a precise 12-step manufacturing process.

? Phase 1: Material Preparation & Warping

Raw Material

Incoming monofilament yarn inspection & testing

Warping

Parallel winding of yarns onto warp beam

? Phase 2: Weaving Preparation

Drawing-In

Threading warp ends through heddle eyes

Reed threading

Threading through reed (reed dents)

? Phase 3: Weaving

Weaving

Plain weave interlacing warp & weft yarns

? Phase 4: Cleaning & Finishing

Washing

Remove spinning oils and process residues

THydrophilic

Treatments

Hydrophilic · Water repellent · Heat setting

°C

Heat Setting

Thermal stabilization for dimensional stability

✅ Phase 5: Quality Control & Dispatch

Inspection

Visual & dimensional QC, pinhole detection

Rolling

Precision winding onto rolls

WAREWARE

Warehousing

Climate-controlled storage

Pack & Ship

Packaging & dispatch to customer

? Weave Types & Their Characteristics

Plain Weave

Most common. Each weft passes over/under every warp. Balanced strength, maximum open area for given mesh count.

Twill Weave

Weft passes over 2+ warps then under. More flexible, better drapability, higher thread density possible.

Plain Weave HD

Heavy-duty variant with thicker threads for same mesh count. Higher strength, lower open area.

Multifilament

Multiple fine filaments twisted together. Higher surface area for fine particle capture, lower flow rate.

✨ Why Choose Synthetic Filter Mesh?

✅ Precision & Consistency
Every square inch has identical pore geometry — guaranteed repeatability batch after batch.

✅ High Strength & Durability
Monofilament construction delivers superior tensile and burst strength compared to nonwoven media.

✅ Wide Chemical Compatibility
PA, PES, and PP options cover most industrial chemical environments.

✅ Reusable & Cleanable
Backwashable, ultrasonically cleanable, and autoclavable — reduces operating costs.

✅ Customizable
Custom widths, lengths, edge finishes, and treatments available per order.

✅ Smooth Surface
Monofilament surface minimizes particle adhesion and facilitates easy cake release.
