US 7,815,978 B2 · Method for controlling a functional property of an industrial fabric

Abstract

A method for manufacturing a papermaker's or industrial fabric requires the application of a polymeric resin material onto preselected locations on a base substrate using an array which deposits the polymeric resin material in droplets having an average diameter of 10μ (10 microns) or more. The preselected locations, for example, may be knuckles formed by the interweaving of the yarns making up the fabric or interstices between the yarns. The purpose of such precise application of the resin is to control functional properties of the fabric, such as permeability and abrasion resistance. The polymeric resin material is set by means appropriate to its composition, and, optionally, may be abraded to provide the polymeric resin material above the surface plane of the base substrate with a uniform thickness.

Dependent claims

A method for manufacturing a papermaker's or industrial fabric, said method comprising the steps of:

a) providing a base substrate for the fabric;
b) depositing polymeric resin material onto said base substrate at discrete locations in a controlled manner so as to control the x, y, z dimensions of said material deposited to create a predetermined pattern in droplets to provide a desired functional property to the fabric;
and
c) at least partially setting said polymeric resin material, wherein the method includes building up at least one x, y, z dimensionally controlled geometric shape with a plurality of the droplets of polymeric resin material, wherein each droplet of the shape is partially set before the deposition of the subsequent droplet when building up the shape.
