What is a Carpet made of?
Face fibre tufted through a woven backing and locked in place with latex — three layers, two of which you never see.
The distinctive smell of new carpet is 4-phenylcyclohexene, a by-product of the styrene-butadiene latex used in the backing, and it dissipates over days with ventilation. Carpet is a difficult product to recycle precisely because the three layers are bonded together with a fourth material, so separating nylon face fibre from polypropylene backing needs dedicated processing that only exists in a few places. The label distinction worth knowing is cut pile versus loop: loop pile resists footprint marks and wears well in halls, but a pulled loop runs, which is why it is a poor choice in a house with a cat.
Component by component
| Part | Material | Why that material |
|---|---|---|
| face fibre | nylon, polypropylene, polyester or wool | Nylon recovers from crushing best and takes dye well; polypropylene is stain-proof but flattens; wool is resilient and naturally flame-retardant. |
| primary backing | woven polypropylene fabric | The tufting needles punch through it thousands of times a minute, so it must not run or tear at the puncture. |
| lock coat | styrene-butadiene latex adhesive | Tufts are not knotted, only pushed through — without the latex the whole carpet unravels from a single pulled loop. |
| secondary backing | woven polypropylene or jute | It gives the carpet dimensional stability so it does not stretch and ripple underfoot. |
| treatments | stain-resist chemistry and antimicrobial finishes | Nylon has dye sites that also grab food colouring; stain-resist agents pre-fill them, which is why untreated nylon stains badly. |
