weight of fabric: this is commonly overlooked by fire spinners when discussing fire safe fabrics. The weight of any fabric directly correlates to how quickly it will ignite and spread. Just like starting a campfire (you use thin wood as kindling), the same goes for fabric – the lighter the fabric, the quicker it will ignite and spread. A nice thick material will give you plenty of reaction time from the moment you make contact with a flame. 6 seconds is a good rule of thumb. If you want to test how long it takes for fabric to ignite, I recommend testing the center of the fabric rather than the edge.
Weave and Structure:
- Feathers, Fur, fringe, fray, velvet, whisker fabric and any dangly fabrics are way more likely to catch fire. This is because the strands are surrounded by oxygen, one of the key components in making a fire.
- Gauze, mesh, tulle, tutus, sheer fabrics are lightweight and see through, this allows air to travel through and spread the fire rapidly.
- Tight knit, thick weave, heavy fabrics like duvetyne don’t allow light or air through, making it harder to catch on fire and slows the spread of the flame.
