Process of forming an embossed surface covering having a wear layer attached uniformly thereto |
摘要 |
The present invention relates to superior wear layer-coated embossed surface coverings which are prepared by depositing a cross-linking inhibitor on at least a portion of the surface of a cross-linkable foam formed on a backing and containing a cross-linking initiator. Preferably a wear layer is applied at this point and cross-linking of the affected areas is accomplished by heating the sheet. The sheet of material is either uniformly or differentially heated and then uniformly compressed to a desired embossing depth using a non-patterned press or roll. The noncross-linked regions remain depressed upon removal of the compressing force whereas the cross-linked regions return essentially to their original height. The wear layer remains in contact with all of the foam regions so that the resulting sheet of material has a wear layer which is uniformly adhered to the contour of the foam layer. The surface of the sheet has an embossed or textured finish.
