VARIETY OF POLYESTER SCREEN FABRICS Polyester Screen Fabrics Types: BOER mainly produces and supplies low-elongation monofilament polyester fabric now for worldwide customers, while there are other types of polyester screen. There are 3 types of polyester fabrics used in screen printing application: Monofilament Polyester Screen Fabric; Low-elongation Monofilament Polyester Screen Fabric; Multifilament Polyester Screen Fabric. Most of today's screen printers use monofilament polyester screen, but the traditional type is rapidly being replaced with "Low-Elongation" polyester screen fabric, which brings many new benefits to the screen printing process. Monofilament Polyester Screen is woven from yarn that is extruded from heated polyester into a single strand. The extruded thread is the spun to a precise diameter. Conventional monofilament polyester screen fabric will elongate under tension: the higher the tension level, the more the thread can stretch. At excessive tension levels, the thread reaches its "plastic deformation" point, and the screen will no longer hold tension. Monofilament polyester is still suitable for non-critical printing applications. In recent years, however, it has been eclipsed by a new development in thread technology: Low-Elongation Polyester.
