The three jobs mesh does
Mesh in intimate apparel is not one material but a set of open-ground warp knits, and it appears wherever one of three jobs dominates. The first job is structure: dense, high-elastane mesh - sold across the trade as powermesh - carries the compression and anchoring work in bra wings, band linings and the support zones of wireless and sports styles. The second is airflow: an open ground lets heat and moisture pass, which is why mesh panels sit at the center front, along the band or across the back of styles meant for warm weather or high output. The third is decoration: sheer grounds read as light and graphical, and fashion bodies lean on that look. A single garment can ask one mesh to do two jobs at once, which is exactly where specifications drift, because a knit chosen for its look rarely carries structure well and a knit chosen for structure rarely looks delicate.
Knit structures behind the names
| Type | Structure | Stretch | Typical use | Watch-outs |
|---|---|---|---|---|
| Powermesh | Dense warp knit, high elastane share | Strong, mostly two-way | Bra wings, band linings, support zones | Elastane quality decides aging; per spec sheet |
| Stretch tulle | Fine open warp knit with elastane | Light, four-way | Cup overlays, sheer panels | Snags; edges need finishing |
| Rigid net and tulle | Open ground without elastane | Minimal | Decoration, embroidery grounds | No recovery; cut edges run |
| Perforated micro knits | Dense synthetic knit, punched or knit-open | Moderate with elastane | Sports and wireless bodies | Opacity varies with perforation |
| Fashion open knits | Fishnet-adjacent grounds | Varies by design | Fashion panty and bralette panels | Comfort at edges; lining decisions |
The table explains why two quotations can name the same style and behave differently: the wing mesh in one may be a true powermesh with a dense ground, and in the other a decorative stretch tulle that fills the same position but does less work. Judging each mesh on a tensioned physical swatch, washed once, is the only reliable comparison. Weight, elastane share and finish should each appear on the spec sheet with a tolerance, because the same trade name covers a wide band of constructions from mill to mill, and a retained swatch per color per lot keeps repeat orders honest.
Sheer fabrics and opacity
Opacity is a construction outcome, not a fiber property. What controls it is the ground density - how many filaments per unit area - plus yarn fineness and color depth. A fine ground in a dark shade can read nearly opaque on the body while the same ground in a pale shade reads sheer, which is why opacity is judged on the approved swatch in the actual color, per program, rather than from a base-fabric sample. Where a program needs coverage held to a stated level, the answer is structural: a lined panel, a denser ground, or a design that places sheer panels where coverage is not the question.
Sheer against skin also raises a comfort and market question. Fine grounds sit comfortably when their edges are finished and the knit is even; a coarse open ground needs a lining or a placement decision. The consumer expectation differs by market and channel, so the desk treats lining as a per-program decision recorded on the tech pack, not a category constant.
Durability: edges, seams and joins
Open grounds fail at their edges and their joins before they fail in the field of the fabric. An unfinished cut edge in a warp knit will run, so every cut edge needs a binding, a fold or a seam that arrests the ground - the stitch families and where each belongs are covered in the stitching note. Strap joins and wing attachments concentrate load into a few courses of yarn; a bar tack or a folded reinforcement at the join prevents the slow tear that starts at the first overloaded loop. Hardware is the third cause: a fine ground snags on hook tapes and adjusters, so smooth hardware and a placement that keeps metal away from sheer panels is a design decision, not an accident. The join itself is detailed in the strap construction note.
Elastane aging closes the list. Powermesh works because its elastane share does constant work, and constant work is what ages elastane; a wing that starts crisp and arrives relaxed a season later is usually an elastane quality or care-route problem, covered in the elastic aging note.
Where each sits in the range
Across the site's lines the placement is consistent. Wireless and balconette styles use powermesh at the wings and band; bralettes use stretch tulle and fashion grounds as the body itself; sports styles use perforated micro knits where airflow matters and powermesh where the impact level does; panties use mesh panels for look and airflow while keeping the gusset a conventional lined construction. Period programs are a special case: their absorbent core is a layered structure specified leak-resistant per spec, and a decorative mesh body sits outside that core, never inside it.
For a program, the practical map is one line per panel: which mesh, which job, which test. A wing mesh should be specified for recovery and elastane quality; an overlay for snag resistance and opacity in the target colors; a decorative panel for edge finish and comfort. Collapse them into one word on the fabric row and the plant will fill the gap with whatever beam is on the shelf.
What to specify
- Name the mesh type per panel and the job it does - structure, airflow or decoration.
- Set elastane share and ground density per component, confirmed per spec sheet.
- Judge opacity on the approved swatch in each target color.
- Define edge finishing per cut edge and reinforcement per join.
- Agree the test panel - recovery, colorfastness, snag behavior - before bulk, and confirm quantities per color in writing on the MOQ and lead time page.
