A nonwoven fabric used for a foamed article reinforcing material to be bonded to a foamed material to reinforce the foamed article is a single-layer material in which stacked layers of a web are bonded together, has a thickness of 1 to 8 mm under a load of 7 g/cm.sup.2, and has a delamination strength of 0.05 to 2.45 N/cm. The delamination strength is a value of the pulling force required to peel the bonded layers of the web apart.

The present invention relates to a band for joining a polyester textile, and to a method for obtaining same, wherein the textile has a printed design, such that the band provides a means for joining the textile and an attachment frame. Advantageously, the proposed band has the same composition as the textile, which facilitates the recycling of the assembly and enables the waste to be reused. For this purpose, the band is formed by a needle-punched nonwoven polyester fabric comprising polyester fibres and bicomponent polyester fibres and has a polyester film on at least one of the surfaces thereof. The claimed invention is of special interest for use in visual communication solutions, such as decorative panels or advertisements at points of sale, in retail, at events and at stands, among others.
