75% Nylon 25% Spandex Compression Interlock Knit is a double-bed interlock knit developed for Sports Bras where controlled support and soft contact at the underband decides whether a style succeeds. The base is 75% nylon 6 filament / 25% spandex, which gives higher power for compression grades that still run on standard knitting machines. The result is a fabric that delivers Compression in daily use rather than only in a laboratory.

Why this construction works
Because a double-bed interlock knit is used, the fabric behaves consistently across the roll: identical faces on both sides, so the fabric stays opaque under tension. 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
- Compression: delivers graduated support while remaining easy to put on, measured by ASTM D2594 stretch and recovery.
- Hand and comfort: higher power for compression grades that still run on standard knitting machines.
- Construction benefit: identical faces on both sides, so the fabric stays opaque under tension.
- 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.
Compression 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
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.
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.
