Abstract

A nonwoven textile assembly, a method for its manufacture, and a spirally wound press felt made from the assembly are disclosed. The nonwoven textile assembly is manufactured by providing a uniform array of parallel yarns having constant height and spacing as a first textile component and which are oriented in a first direction. An adhesive material is applied to a first side of the first component. A second textile component, such as a second array of parallel yarns oriented at an angle of from 2.degree. to 90.degree. to the first, or a nonwoven mesh, or a nonwoven scrim comprising a regenerated cellulosic is then laid over the adhesive material. A lightweight batt layer optionally including a second adhesive preferably located on the side of the batt facing the second side of the second textile component, is overlaid the second textile component. The assembled first textile component, adhesive component (if applicable), second textile component, adhesive component (if applicable) and batt, is then passed through a pressure zone which is preferably heated so as to activate the adhesives and securely hold the first and second textile components in place along with the batt material. Optionally, the batt material may contain bi-component fibers of which one of the two components is a heat activated adhesive. The resulting nonwoven textile assembly may then be needled in a needling unit downstream of the heated nip, or otherwise processed. A spirally wound press felt comprised of at least one helically wound, abutting strip of the nonwoven textile assembly is provided.
