No thanks, I don't want to prevent hand injuries.
Just hearing a glove contains fiberglass gives a lot of people itchy fingers. But chances are that you’ve worn gloves with a fiberglass core and didn’t even know it. Common alternative names include: silica-infused fiber, composite filament fiber and glass wool (which sounds a lot worse to me than fiberglass). Today on the blog, we’re going to set the record straight on fiberglass and get rid of its bad wrap once and for all.
Fiberglass won’t exist in a glove on its own. Most commonly, this yarn is combined with other types of high performance yarns like Kevlar® or TenActiv™. It’s wrapped or twisted with Kevlar® or Dyneema®, and then wrapped with nylon or cotton to improve the glove’s comfort. The wrapping and twisting process is vital. If improperly performed, bits of fiberglass will stick out and irritate the skin. But if it’s done correctly, the fiber will go unnoticed.
Below is a close-up of what poorly-wrapped fiberglass looks like. See those pieces of fiber poking out? That’s what makes your hands so itchy!
And here’s what it should look like:
Sounds bad if you want a sharp blade but if it’s protecting your hands from harm, it’s a quality you want! Fiberglass dulls knife blades which means that it helps make your gloves even more cut resistant. This is because it is very hard so it has a dulling effect on sharp edges and blades. When paired with another high performance yarn like Kevlar®, composite-filament fiber provides 500 to 1000 grams more cut resistance, without hindering hand movement.
It’s not uncommon to need a high cut-resistant glove that can also handle hot materials. This fiber is the optimal choice for heat because the most common alternative for engineered yarns — stainless steel — has thermal conductive properties.
This is a cost-effective option for added cut resistance that won’t inhibit dexterity.
So there you have it, four simple reasons for making the fiber a part of your protective lineup.
