Method for controlling a functional property of an industrial fabric and industrial fabric
First Claim
1. A papermaker'"'"'s or industrial fabric for the manufacture of paper or nonwoven products thereon, the fabric comprising:
- a base substrate; and
a predetermined pattern of three dimensionally controlled polymeric resin material deposits formed at discrete locations on said base substrate, said deposits comprising one or more individually placed droplets of polymeric resin material of between about 10 and 100 microns in diameter, and wherein said fabric is made in a manner 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 wherein each deposit comprises one or more individually placed droplets of polymeric resin material, to provide a desired functional property to the fabric; and
c) at least partially setting said polymeric resin material,said deposits having a three-dimensional shape selected from the group consisting of a cube, a cylinder, a cone, a cuboid, an oval cylinder, and a trapezoid.

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.
