Polyester was introduced to the screen printing market over 40 years ago and quickly replaced traditional silk as the fabric of choice among screen printers all over the world. It is a material that is uniquely suitable for screen printing because of its tensile strength, elastic memory and resistance to chemicals, abrasion heat and moisture. There are 3 types of polyester fabrics used in screen printing and they are monofilament, low-elongation monofilament and multifilament. Most of today's screen printers use monofilament polyester, but the traditional type is rapidly being replaced with "Low-Elongation" fabric, which brings many new benefits to the screen printing process.
