This technique is mainly used to attach foam to a textile fabric, which is widely used in automotives. As displayed in figure 9 the foam is presented to the flame, which encourages melting; as it then dries it bonds the textiles. This technique has associated health and safety risks due to the release of gases when melting takes place.

Hot melt lamination
There are two processes involved in hot melt lamination, the application of a thermo-set adhesive, and the fusing of the fabric and the non-textile component through heat and pressure. Adhesive is applied either to the whole surface, or discreet, where the adhesive is applied as a thermo-set, which just attaches in patterns, such as glue dots. Discreet provides greater flexibility due to the reduced contact areas.
