A classic among hook-and-loop fastening technologies – also available with a locking mechanismSewn, tear-resistant solutions for multi-layer connections

Is double better? Not necessarily. When it comes to hook-and-loop fastening systems, multi-layer material connections in particular benefit from the classic joining technology and processing method – sewing. So that double really does mean secure. Do you want to lock materials together particularly securely? kragoTEC® is also ideally positioned technologically for this ...

But first, let's look at the purpose of multi-layer connections: when developing customised solutions for applications that require multi-layer connections – for example, to attach additional loops – it may be advantageous to opt for sewn fastening solutions. In other cases, however, the decision in favour of ultrasonic technology could be more effective. Especially when different surfaces and materials need to be permanently, firmly – and above all inseparably – connected to each other, the ultrasonic welding process can offer significant advantages over sewn connection solutions.

Benefit from sewn connections: tension belts, restraint belts, etc.

As a general rule, it is important to weigh up the options as precisely as possible: ultrasonic welding or sewing? This also applies to projects in which, for example, very long seams would be impractical or inefficient. Nevertheless, other projects, such as hook and loop systems on tension belts for the logistics industry or restraint belts, for example for use on wheelchairs or similar, benefit from sewn processes. But what about the fastening of materials?
