A bonded fabric joins two or more textile layers with an adhesive, heat or ultrasonic energy — there is no separate film doing the work. A laminated fabric fuses a thin membrane or film (polyurethane, PTFE, PVC) onto a substrate with heat and pressure, and that film is the barrier. The membrane is the reason laminates block water and wind while a plain bonded cloth usually does not.
Bonding is an assembly step, not a coating on one side. The usual routes are:
Because two cloth layers are simply stuck together, the result is generally softer and more flexible than a laminate — but a bonded cloth is not waterproof by default.
Lamination adds an actual film layer. A foam-laminated construction (the classic three-layer: face fabric + polyurethane foam + backing) is the textbook example, but the high-performance version is a functional membrane (PU, PTFE/Teflon-type, or PVC) bonded to a face fabric. That continuous film is what makes the cloth windproof and water-resistant or waterproof. The cost is stiffness and reduced breathability unless the membrane itself is microporous.
Buyers often hear "bonded is more breathable than laminated" and stop there. It is only half true. A bonded cloth can breathe better when the adhesive is applied as a discontinuous pattern — dots, grid or a porous coat — leaving air pathways. But if the adhesive is laid as a continuous film, it seals the cloth as effectively as a laminate. So the question to ask is not "bonded or laminated?" but "what is the bond pattern and film weight?" For any moisture claim, ask for a quantified figure — hydrostatic head (ISO 811 / AATCC 127) or a water-column rating — rather than the word "breathable", which is used across a very wide range of performance.
| Construction | What it is | Waterproof? |
|---|---|---|
| Bonded | Two+ fabric layers joined (adhesive / heat / ultrasonic) — no separate film | Not by itself |
| Laminated | Fabric + membrane / film fused with heat & pressure | Usually yes (film dependent) |
| Coated | Single fabric with a polymer, rubber or PU layer on one side | Often yes |
| Double-knit | Two layers integrated during knitting; no adhesive at all | No |
These are easy to confuse in a supplier email. A clear way to separate them: ask how many layers there are, what fibre is in each layer and its weight, whether any membrane, foam or film was added, and which joining method was used.
Bonded and laminated structures are harder to repair once layers are joined. In use they fail by delamination — edge separation after cutting, puckering, or peel loss after repeated flexing, washing or heat. Practical care: gentle wash, air dry, and avoid high dryer or iron heat, which degrades the adhesive or film. Always test the bond after the same laundering and exposure the finished product will see, not just on a fresh sample.
We are an integrated woven mill — yarn dyeing → weaving → fabric dyeing → printing → finishing, all on one site. The woven face layer in many bonded and laminated constructions is exactly the cloth we weave in-house: poplin, twill, canvas, oxford, chambray and yarn-dyed shirting. The bond or laminate step is a separate converting process, so tell us your target construction and we will confirm at enquiry what we can supply and coordinate. Where an after-treatment such as a water-repellent finish (DWR) is needed, it is applied on our own finishing line. Specific membrane type, adhesive, peel strength and process route are available on request and confirmed in writing at the enquiry stage.

Not by itself. A bonded cloth joins layers with adhesive, heat or ultrasonics and has no barrier film, so it is usually only water-resistant at best. Real waterproofing comes from a laminated membrane or a coating, plus sealed seams. If moisture resistance matters, ask for a hydrostatic-head or water-column figure with the test method named.
It follows the end use. Choose laminated when you need a windproof / waterproof barrier (rainwear, tarpaulins, technical shells). Choose bonded when you want the combined properties of two cloth layers — softer hand, insulation, structure — without a hard film, accepting that it is not a waterproof barrier by itself. The bond pattern decides breathability either way.
The terms are not regulated, so one supplier's "bonded" may be flame lamination while another's is TPU film bonding, and a third may mean a double-knit. Rather than rely on the word, ask for the layer count, the fibre and weight of each layer, whether a membrane/foam/film was added, and the exact joining method. That description is the real specification.
We weave the woven face fabric used in these constructions in-house and finish it on our own line. The bond/laminate assembly is a separate converting step; tell us your target construction and we will confirm at enquiry what we can supply and arrange. Membrane type, adhesive and peel strength are available on request and agreed in writing before bulk.
