Fiberglass Sewing Threads

For the sewing of the fiberglass filter bags, our company develop this high temperature resistant sewing thread.

We select the excellent alkali free fiberglass yarns as the material.

After coating with PTFE, the thread is more smooth and soft, abrasion resistant and chemical erodsion repellent.

The fiberglass filter bags which were sewed by this product can work at high temperature up to 280 DC without any crazes.

It can be used in high speed industrial sewing machine, without making any untwisting. It can be handsewn either, but its abrasion resistence will be weaken, which didnt desrver our recommendation.
