What does it mean to double gas threads? Well, here at WonderFil it’s how we get our threads to be so smooth and low on lint! The process of double gassing is actually quite simple. We start with the threads as they are, a little bit wild! Cotton threads especially will have a visible halo of lint around the thread. If you hold a low quality cotton thread up to the light, you might see small fibers sticking out of the thread, and lots of them resembling a case of really bad bed head! Double gassing is the process that gets rid of this, but how you ask?

Double gassing is the process of burning off the lint! The first pass will burn off 80% of the surface lint, resulting in an already much cleaner, much lower lint look. We send our threads through for a second run, burning off an additional 80% of the remaining thread. This gives the thread amazing low lint qualities, a smooth surface, and an excellent stitch quality!

We’ve all had to clean lint out of our machines at some point, and it can be quite difficult to get into the tiny nooks and cranny’s. When you have a double gassed thread, the lint is just that, lint! Some companies use sprays, glues and lots of other sticky substances to glue the lint down to the thread. Now imagine trying to clean out your sewing machine when the lint is sticking to the inside of your machine due to the sticky adhesives and residues, Yikes!
