Systemmag technology

A magnetic closure designed as a textile architecture.

Systemmag’s performance comes from a whole system: alternating polarities, flexible substrates, protective pockets and a qualification protocol. The goal isn’t to glue on a magnet: it’s to integrate a measurable behaviour into your product.

Magnetic principle

An alternating-polarity architecture to concentrate useful force.

Systemmag doesn’t rely on an isolated magnet, but on a periodic organisation of polarities. The North/South alternation concentrates the field over a useful length, guides self-alignment between two complementary faces and increases the available holding force.

Isolated magnet

A single magnet spreads its field around its volume. The useful zone stays short and less controlled in a textile substrate.

Systemmag architecture

A succession of alternating-polarity modules creates field bridges between two complementary faces, with hold distributed along the length.

Key terms

The words of magnetic closure

Alternating polarity: The magnets alternate north and south along the whole closure. Both sides attract each other and settle into place by themselves, and the hold spreads along the whole closure instead of a single point.
Peel opening: You pull the two sides apart from one end: the closure comes away progressively, with no anchor point and without pulling against the whole hold at once.
Magnet block: A segment cut to the required length from a BA magnetic strip, then slid into a pocket or a sheath.
Sheath: The textile housing, sewn into the product, that protects the magnet block and keeps it invisible in the finished product.

Nine international patents

The magnetic fastening, its manufacturing process and several applications (lingerie, radiology protection, accessory holders) are covered by nine patents in France, Europe and the United States. Each number links to its publication.

Qualification & uses

Functional tests on prototypes

Trials in real conditions of use

Textile & process compatibility

Traceability & quality control

Each configuration is validated on the real substrate: material, thickness, attachment method, usage cycles and production constraints.
