Developed for Base Layers, this Rib Knit answers the most common brief we receive: next-to-skin comfort with continuous moisture movement. The yarn package is polyester elastane with a bio-based chitosan finish, chosen because it provides a bio-derived antibacterial route for restricted substance sensitive programmes, and the finished cloth is set and tested so that Thermal Brushed.

Why this construction works
Because a rib knit is used, the fabric behaves consistently across the roll: high extension across the width with clean recovery, ideal for cuffs and bands. That consistency is what lets a factory cut confidently and lets a brand repeat an order a season later with the same result.

Performance features
- Thermal Brushed: traps warm air while staying light enough for active use, measured by ISO 11092 thermal resistance.
- Hand and comfort: a bio-derived antibacterial route for restricted substance sensitive programmes.
- Construction benefit: high extension across the width with clean recovery, ideal for cuffs and bands.
- Consistency: GSM and width tolerance are locked per lot and recorded on the inspection sheet.
- Durability: performance is verified after repeated washing, not only as delivered.
Recommended applications
Used for Base Layers and for the accessories around them. next-to-skin comfort with continuous moisture movement is the reason it is chosen, and the fabric bonds, prints and sews on standard machinery without special settings.

Thermal Brushed fabric prepared for Base Layers production
Dyeing, finishing and customisation
The fabric can be supplied greige, piece dyed or printed. Add-on finishes are selected after a wash durability trial, because a finish that disappears after five washes is worse than no claim at all.
Care instructions
- Machine wash at 30 degrees with mild detergent, no fabric softener.
- Dry away from direct heat and do not tumble dry hot.
- Cool iron on the reverse if needed, and avoid bleach.
Ordering, sampling and quality control
Minimum trial order is 300 metres per colour and bulk production takes 20-25 days once the approval sample is signed. Documentation includes test reports per lot, OEKO-TEX conformity and full construction sheets.

Frequently asked questions
Can we get recycled content with this construction? In most cases yes. GRS certified recycled nylon or polyester can replace the virgin yarn with full chain of custody documents, usually with no visible change in hand or performance.
Is the performance tested on every lot? Yes. The named test method is repeated on bulk fabric, not only on the approval sample, and the report carries the lot number so results can be traced back.
