Developed for Sports Bras, this Spacer Knit answers the most common brief we receive: controlled support and soft contact at the underband. The yarn package is nylon spandex with copper bearing filament, chosen because it provides antibacterial action plus faster heat transfer away from the skin, and the finished cloth is set and tested so that Thermal Brushed.

Why this construction works
Because a spacer knit with two faces is used, the fabric behaves consistently across the roll: cushioning and airflow built into a single piece of fabric. 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: antibacterial action plus faster heat transfer away from the skin.
- Construction benefit: cushioning and airflow built into a single piece of fabric.
- 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 Sports Bras and for the accessories around them. controlled support and soft contact at the underband is the reason it is chosen, and the fabric bonds, prints and sews on standard machinery without special settings.

Thermal Brushed fabric prepared for Sports Bras 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
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.
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.
