1. Polyester Mono filament mesh are made from single threads formed thick enough to be directly woven into smooth, regular fabrics. It 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 mono filament 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. It has high dimensional stability and is capable of allowing perfect registration. It is particularly workable when fine detail is important.
Polyester mono filament mesh 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. Most of today's screen printers use mono filament polyester than other materials. But the traditional type is rapidly being replaced with "Low-Elongation" fabric, which brings many new benefits to the screen printing process.
Mono filaments are the most concise and regular fabrics. The single strand threads are capable of exact detail and registration. They also wear well in extended production printing. It is less easy to adhere films and emulsions with mono filaments than with multi filaments, but they are easier to clean and to reclaim and less likely to clog during printing. The surface of the threads is less coarse, or more smooth and polished. More details about polyester mono filament mesh from MAISHI MFG. GROUP,
Multifilament Polyester are made from fine polyester strands twisted together into threads and woven into fabrics. This is common used in the textile industry. The threads are coarse and subtly impart that quality to the images printed. They are closest in visual character to the original multifilament silks used in screen printing. They wear less well in extended production runs than do monofilaments, but they can be used to print on textured or contoured surfaces. This mild elasticity prevents exacting registration. Multifilaments are also preferred for the easier adhesion of indirect cut and photo stencils.
2. What is the advantage and dis-advantage between two types of mesh?
The softness of multifilament mesh is low, and the touch and appearance of the staple fiber are unsatisfactory.
The polyester monofilament mesh have the charactoristics of high tension and low elongation while the multifilament mesh don’t have.
The Polyester monofilament mesh is Low elongation and high tensile strength. This mesh is what we are producing now in a wide range of mesh counts, and our products offers significant advantages over the traditional mono filament polyester:
· Faster tensioning without damage to the threads.
· Improved fabric strength.
· Faster tension stabilization.
· Higher tension threshold and breaking point.
· Less tension loss during the stretching process.
· Faster turnaround time from the screen room to the pressroom.
· Improved registration due to stable tension.
· Faster Print speeds.
The multi filament mesh price is a little higher than mono filament mesh. But mono filament polyester is still suitable for non-critical printing applications recently. For more detailed discription about mesh from MAISHI MFG. GROUP, please click links:
