Delivers Durability
3M™ Loop Fastener SJ3401 is our general purpose loop fastener that features no adhesive or liner. It is an attachment alternative to a wide variety of closures, including zippers, screws, snaps, hooks and more. We designed this fastener with a woven loop backing, covered with thousands of soft, pliable napped loops, providing for thousands of openings and closings (cycles). Commonly paired with 3M™ Hook Fastener SJ3402, this loop fastener can also engage with other 3M™ Hook Fasteners. To ensure stability and flatness, both the hook and the corresponding loop are preshrunk.
Recommended Applications
- Uniforms
- Gloves and clothing
- Securing fabric to furniture cushions
- Carpet panel attachments
No Adhesive or Liner for Easy Customization
The backing of 3M™ Loop Fastener SJ3401 is free of adhesive or liner, allowing for easy customization. The fastener is most commonly attached by sewing, but can also be applied using hot melt or liquid adhesives (temperature resistance may change based on adhesive used). It provides a tailored appearance for fabrics and garments and is both washable and dry cleanable.
Secure, Repeated Closures
3M™ Hook and Loop Fasteners offer great design flexibility, fast product assembly, smooth and clean exterior surfaces and excellent product performance in many applications. 3M Hook and Loop Fasteners consist of hooks and loops which engage to form a quick fastening attachment. To disengage the attachment, simply pull the strips apart by hand.
Bringing it All Together
3M™ Hook and Loop Fasteners provide the strong, tough attachment solutions you need. Simply press together and the tiny, stiff hooks mesh with pliable loops to create a quick, secure fastening system. Backed with a variety of 3M adhesive technologies, you can easily meet application demands that require thousands of easy opening and closings.
