Flame lamination

Textile uses are a relatively stable area and consist of the lamination of polyester foams to textile products, usually by flame lamination or electronic heat sealing techniques. Flexible or semirigid foams are used in engineered packaging in the form of special slab material. Flexible foams are also used to make filters (reticulated foam), sponges, scmbbers, fabric softener carriers, squeegees, paint appHcators, and directly appHed foam carpet backing. 

In most textile applications a cloth lining must be sewn against the foam side. A comparatively new adaptation of flame lamination is now being used to obviate this step. In this method two fabrics form a sandwich with a very thin foam interlining. One fabric is flame-laminated to one side of the foam, followed by flame laminating of another fabric to the other side. After flame laminating so much of the foam is used up that it in reality is only acting as an adhesive. In this way a liner is adhered in place, rather than sewn, with little or no loss in...

The second method of thermal bonding utilizes nets and webs of thermoplastic material this is now challenging flame lamination. Co-extruded nets, where one polymer acts as a cheap carrier for a lower-melting, more expensive polymer, are also available. 

Flame lamination is another hot-air bonding process that is used mainly to continuously join fabric to foam. A foam sheet is passed over an open flame to create a thin layer of molten polymer on the foam surface, which is then mated with a fabric by passing the assembly through a set of rollers (Figure 13.5). The molten foam surface acts as an adhesive when it cools. PU foam is the most frequently used material in flame lamination.
