HOT FILM LAMINATION (VACUUM ASSISTED) FOR CARPET BACKING APPLICATION

摘要

PROBLEM TO BE SOLVED: To provide a tufted carpet of good bond strength between primary and secondary backings.

SOLUTION: A process for laminating a substrate may include steps of: disposing at least one a thermoplastic film on a porous substrate; heat softening the at least one thermoplastic film; conjoining the at least one thermoplastic film and the porous substrate to form a laminated substrate; and cooling the laminated substrate. The step of conjoining includes a step of suctioning the thermoplastic film into the porous substrate.
