Polyester sewing thread is an industrial sewing thread made from high-strength polyester fibers. Characterized by excellent strength, abrasion resistance, heat resistance, and dimensional stability, it is widely used in the production of industrial filter bags and filter fabrics, as well as in various other industrial sewing applications.
In the bag-type dust collection industry, polyester sewing thread is one of the most commonly used materials for stitching dust filter bags designed for ambient and low-to-medium temperature operations; it ensures strong, stable seams and extends the overall service life of the filter bags.
