Yes, these images are much, much better and clearly show the fibers (yes fibers not worms) are embedded in the materials. The only problem with this source is the speculation as to the nature of the fibers- they assume the colored (red, blue, black) fibers are deliberately put there. In textile manufacture you will invariably end up with stray fibers making it into your final products since the factory is saturated with fibers in the air and on all equipment, tools and people who work there. Products will also pick up stray and random fibers in the environment which is why forensic fiber analysis is done for murders and the like. Nothing is pure in this world and textile fibers end up in every single thing at some point. Who knows just how many of such stray fibers we have all eaten, drank or breathed in our lifetimes. One only need to look at the dust in your home under a bit of magnification to realize that monofilament dust is everywhere and makes up most of the airborne particulates in our homes. These masks will collect them as well both during manufacture and use. It's just how it goes in the real world. We need more investigation like this but with less jumping to conclusions and more scientific honesty. Otherwise I think they did a good job on the photos. It certainly has gone a long way to give me a sense of confidence that these fibers are not worms or nefarious nanotech but simply mundane monofilament dust contamination.
