88% Polyester 12% Spandex Thermal Brushed Spacer Knit is a spacer knit with two faces developed for Sports Bras where controlled support and soft contact at the underband decides whether a style succeeds. The base is 88% polyester filament / 12% spandex, which gives the workhorse blend for training ranges that wash repeatedly. The result is a fabric that delivers Thermal Brushed in daily use rather than only in a laboratory.

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: the workhorse blend for training ranges that wash repeatedly.
- 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
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.
What is the minimum for a first order? Development starts at 300 metres per colour, which is enough for a proper wear trial and a small capsule. Bulk pricing improves at 1,000 metres and above per colour.
