Fiberglass cloth

I bought some 6 oz fiberglass cloth and it has a bunch of what was called "runs" on nylon stockings. Is that just par for the course or did they unload some seconds on me. I expected it to be pretty uniform. I realize that the fibers are not attached to each other but it seems like you would have to catch it on something to move the fibers like that. LP

It happens. Like you said it's often because it snags on something.

Sometimes you can use a stiff bristled brush and correct it somewhat.

It won't hurt anything or be noticeable.

Larry, I'm not seeing what I'd refer to as the equivalent of actual runs in old nylons, which would be missing yarns or what's known as "picks" in fiberglass-ese. What you show is where the cloth has been snagged and distorted by rough handling somewhere in either manufacture or pulling the order for you and bundling it up for shipping. As Alan says, you can often brush it out, but be careful and don't use a real stiff brush as you can damage yarns. Finding the ends of those yarns on each side of the cloth and pulling them,
"stretching" them, may straighten it out somewhat, maybe even enough so that it won't bother you as much, but I wouldn't worry about it even as is. Again, as Alan said, it won't be noticeable or even affect strength much.

Good point. I was referring to something like a chip brush rather than a soft bristled paint brush but now I see it could easily be taken the wrong way.

Those are from handling.

Yes, a brush will help, but they won't likely show, when wetted out.

I would get them, when pulling on the cloth, over the shearline. Any rough edge, will snag, and cause that.

Yes. I work with my hands so they're always rough. When I'm laying out cloth, I wear latex gloves so I don't snag the fibers. Smoothing it with a soft-bristled brush works better than your (gloved) hands also.

As previously stated, nothing to be concerned about but I wear the gloves so that I don't create more of those areas.

When I was still working full time, my hands were also quite rough, and I caused snags like those when smoothing out the cloth.
I learned to quickly sand my hands smooth...that.s right, sand my hands. A once over with some 320 grit did wonders to avoid messing up the weave.

Thanks all. I was wondering why no one replied but I must have turned off notifications without realizing it.
