Rob is fascinated with the velcro-like fasteners he's finding on his baby's clothes, diapers, etc. He's been shooting highly magnified pictures of the different kinds of closures and annotating them with delighted little notes about the many ways that this stuff is changing.
The diapers have two small patches of this tape, each less than one square inch of area. To the naked eye, the patch looks like a bit of shiny sandpaper.
The structure of this "hook and loop" fastening tape is very small…
This new velcro hook looked like a crop of plastic mushrooms.
Tiny mushrooms, which appeared to have been extruded rods out of a flat sheet, squashed flat my a hot roller, or microscopic Mario brother.
And here are a couple photos of the "loop" side of the fastener. Strands of very fine nylon threads stretched between wide rows of chain stitch.
Unlike regular velcro, this "loop" half of the fastener does not feel fuzzy. It feels flat and soft, like the surface of a cardboard box.
This product is apparently called "Microplast", and was developed by a company called Binder.
