Abstract
A flexible laminated surface material has an outer material and a laminate wadding composed of a fibrous web and a nonwoven fabric sheet that are together needle punched. Parts of filaments of the web penetrate through the nonwoven fabric sheet, thus forming many small protrusions on the nonwoven fabric sheet. The outer material is adhered, using entire area or spot adhesion techniques, to the nonwoven fabric sheet side of the wadding with a substantial adhesion strength. By varying the amount of the adhesion applied, different types of adhesion can be achieved.
