Graphene Modified Yarn for Cycling Jerseys: Fabric Specification
This is the specification we issue for cycling jerseys when the brief calls for genuine odour control rather than a marketing claim. It is built around Graphene Modified Yarn.
Base construction
polyester knit with mesh side panels at 110-150 GSM. The structure is chosen so the back panel under the pockets is covered by the treated surface, because odour-control chemistry only works where sweat actually reaches it. The sweat zone for cycling jerseys is the back panel under the pockets, which is where the treatment has to sit.
Odour-control system
Graphene Modified Yarn: graphene platelets dispersed in the filament. The mechanism is simple: the platelets create a surface that bacteria colonise poorly while also spreading heat. This suits polyamide filament yarn, which is what we knit this product from. Every lot is measured against ISO 20743 plus far-infrared emissivity before the fabric is released for cutting.

Performance targets
The fabric must reach bacterial reduction above 95% with far-infrared emissivity above 0.88 when tested to ISO 20743 plus far-infrared emissivity. The same test is repeated per production lot, and results below the target are rejected rather than negotiated. Cost impact is a yarn premium of 12-18%, which is usually recovered through fewer returns across a season.
Comfort and other targets
Odour control must not come at the cost of comfort. Moisture management is checked to AATCC 195, dimensional change to AATCC 135, and hand is approved against a sealed reference sample. Wear trials were run under road and indoor cycling rather than in the laboratory alone.
Care labelling
The label states standard home laundering without bleach. This wording is not decoration: it is the condition under which permanent, because the additive sits inside the fibre was measured, and ignoring it shortens the service life of the finish. The care label states standard home laundering without bleach, and that wording is the condition behind permanent, because the additive sits inside the fibre.
