What Is Mesh Fabric?
Mesh Fabric, or 网眼布, is a textile with deliberate open spaces formed between yarns or knitted loops. It may be warp knitted, weft knitted or woven, with construction determining stretch, stability, edge behavior and hole consistency. Buyers should define aperture dimensions, open area and air permeability separately because visible hole size alone does not predict airflow or end-use performance. Fiber, yarn diameter, fabric thickness, tension and finishing also affect the result.
Common Specifications Buyers Compare
SpecificationCommon OptionsBuyer Note
ConstructionWarp knit tricot, warp knit raschel, weft knit, plain woven, leno woven and monofilament woven.Name the machine and structure because similar-looking meshes can have different stretch, recovery, edge stability and cost.
Fiber contentPolyester, nylon, cotton, polypropylene, elastane blends and supplier-dependent specialty fibers.Polyester is widely used for dimensional stability and drying, while nylon can provide softer hand and abrasion resistance; actual performance depends on yarn and finish.
Yarn specificationMonofilament, flat filament, textured filament, spun yarn and covered elastic yarn.State filament type and linear density because yarn bulk and diameter influence coverage, hand, strength and airflow.
Fabric weightLightweight, midweight and heavyweight ranges with buyer-defined tolerance.A typical single-layer apparel mesh may fall near 40-250 GSM, but industrial, spacer and heavily finished constructions can sit outside this indicative range.
Aperture size and shapeRound, square, rectangular, diamond, hexagonal and patterned openings.Measure width and length in millimeters on relaxed, conditioned fabric and define whether the value is nominal, average or a permitted range.
Open areaPercentage of surface occupied by openings, measured or calculated under a defined condition.Open area often predicts ventilation and visibility better than mesh count alone, but the measurement method must be agreed.
Fabric countCounts per centimeter or inch, reported by fabric direction.For woven mesh, record ends and picks separately; for knitted mesh, record wales, courses or pattern repeat without treating these values as direct aperture measurements.
Air permeability pressure test differential area unit reporting requirements.Buyer-defined minimum, target and tolerance under one specified test condition.Use ASTM D737 or ISO 9237 as agreed, and keep pressure differential, test area and units consistent across suppliers.
Main Applications
Use lightweight knitted mesh for sportswear ventilation panels, jersey inserts, linings and pocket bags when stretch and soft hand are required.Use stable woven mesh for screens, laundry products, bags and technical separation layers where controlled openings and low stretch matter.Specify abrasion, flexing and dimensional stability for footwear uppers, tongues, backpack panels and equipment pockets.Use spacer mesh for padded footwear, seating and protective components, but specify total thickness, compression recovery and face constructions separately.Validate aperture dimensions and finished-product geometry for insect barriers because generic mesh count does not confirm exclusion performance.Treat filtration and particle-retention uses as engineered applications requiring validated aperture distribution, airflow and retention data.
How Buyers Should Source It
- Approve mesh against a sealed physical standard that records construction, GSM, aperture dimensions, color and finish.
- Evaluate samples over the actual lining, foam or body fabric because backing color and contrast change the perceived shade and openness.
- Ask the mill to report aperture measurements in both machine and cross-machine directions for rectangular or directionally unstable openings.
- Test finished and laundered fabric when heat setting, dyeing or washing may alter hole dimensions, shrinkage or airflow.
- For conversion between suppliers, match yarn specification and construction rather than copying only GSM and mesh count.
- Conduct pilot cutting and sewing because open structures may require adjusted seam allowance, stitch density, needles, binding or reinforcement.
- Inspect roll consistency at the center and edges because widthwise tension can change aperture shape and usable width.
- For performance claims, test the complete material assembly because laminates, print, foam and lining can restrict airflow.
RFQ Checklist
- State whether the required construction is warp knit, weft knit or woven because machine type affects stretch, stability, sampling options and price.
- Specify fiber percentages and yarn form, including filament, textured filament, spun or monofilament, because yarn selection affects hand, abrasion and airflow.
- Provide the target GSM and tolerance for conditioned finished fabric so weight changes cannot substitute for an approved structure.
- Define aperture width, aperture length, shape and tolerance in the relaxed conditioned state because knit openings change under tension.
- Request open area as a percentage when airflow, visibility or particle passage is critical, and agree on the image-analysis or calculation method.
- Set the air-permeability method, pressure differential, test area and reporting unit so laboratory results remain comparable.
- Specify usable width and whether it is measured relaxed, open-width or under agreed tension because mesh edges can curl or distort.
- Define stretch and recovery requirements by direction, including the applied load or extension, because knitted mesh can deform during wear and sewing.
- List required color, optical standard and lighting condition because open structures can appear lighter over different backings.
- State all finishes, including wicking, antimicrobial, flame-retardant, water-repellent or coating treatments, because they can change airflow, hand and cost percentage-wise significantly actually maybe no, remove?
Common Mistakes to Avoid
- Using mesh count as a complete hole-size specification ignores yarn diameter, construction and opening geometry.
- Approving airflow by hand feel alone can hide significant differences caused by finishes, coatings, thickness and test pressure.
- Measuring stretched knit mesh produces aperture dimensions that may not represent the relaxed fabric in the finished product.
- Comparing air-permeability results from different test methods, pressure differentials or units can produce misleading conclusions.
- Specifying only GSM allows suppliers to change yarn size, hole pattern or density while technically meeting the fabric weight.
- Selecting an open mesh without checking snagging and abrasion can cause early damage in footwear, bags and equipment.
- Ignoring edge curl, fraying or run behavior can create cutting losses and unstable seams during garment production.
