Nylon 66 High Tenacity Spandex Thermal Brushed Brushed Fleece Knit is a brushed back fleece knit developed for Base Layers where next-to-skin comfort with continuous moisture movement decides whether a style succeeds. The base is nylon 66 filament with high tenacity spandex, which gives higher melt point and better abrasion resistance for demanding uses. The result is a fabric that delivers Thermal Brushed in daily use rather than only in a laboratory.

Why this construction works
Because a brushed back fleece knit is used, the fabric behaves consistently across the roll: a soft inner face that traps warm air without heavy weight. 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: higher melt point and better abrasion resistance for demanding uses.
- Construction benefit: a soft inner face that traps warm air without heavy weight.
- 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 the weight and width be changed? Yes. Most programmes run between 140 and 340 GSM, and width can be set between 150 and 180 cm to match your marker. Changing weight changes cover and stretch, so we re-test before confirming.
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.
