Process of stretching polyester bolting cloth

Polyester bolting cloth can be widely used in screen printing industry. And stretching polyester bolting cloth is important. So what is the process of stretching polyester bolting cloth?

Stretching is the first step in making screen plates. The quality of the stretch net has a direct relationship with the quality of the plate. Therefore, we must carefully and meticulously prepare for the work before stretching.

Firstly, according to the printing size, the corresponding mesh frame is selected, and the side of the mesh frame and the mesh is cleaned. If it is the first frame used, it needs to be gently rubbed with fine sandpaper to make the surface of the frame rough. This is easy to improve the adhesion between the frame and the screen. If the frame is used, it should be rubbed with sandpaper to remove the residual glue and other substances. Before cleaning the mesh frame, pre-coat a sticky adhesive on the surface in contact with the screen and dry it. When stretching the net, use manual or mechanical stretching, and the screen is tightly tightened to make the screen and the frame close to each other, and the screen is in contact with the frame. Partially recoating the adhesive, and then drying it. Note that the adhesive should not be too thick or too thin. When drying, use a rubber sheet or a soft cloth to wipe the bonded part and apply a certain pressure. Make the screen and the frame more firmly bonded. After the adhesive is dried, loosen the external tension, cut the wire around the outer edge of the frame, and then use a single-sided self-adhesive tape to attach the wire to the frame where the mesh is bonded. The function of the net and the net frame can also prevent the dissolution of the solvent or water on the adhesive during printing to ensure the effective use of the screen printing plate. Finally, rinse the screen with water or a cleaning agent. After the screen is dried, it can be used for photoresist coating (plate making).
