Lamination is a term used to describe a process in which two or more substrates are brought together to form an integral layered structure. Lamination can take place either via a wet method or a thermal method. In the wet process, a binder solution is applied to one or more substrates. The layers are then brought together while they are still wet and the structure is dried with all the layers compressed together to ensure a good bond. In the thermal process, the different layers are brought together and consolidated with heat and pressure. At Saint-Gobain Technical Fabrics, this process is also called Bamilex®. Calendaring is another thermal process where heat and pressure are used together. Although calendaring is similar to thermal lamination, there is one difference between them. In thermal lamination, the layers are consolidated without distortion. In calendaring, the physical appearance of the fabric is normally altered. A fabric can be flattened by calendaring to reduce thickness. Calendaring can also be used to remove surface unevenness or to close the openings in an open mesh fabric.
