Abstract
A method for manufacturing a belt and a belt for use in the production of bulk tissue and towel, and of nonwoven articles and fabrics, requires the application of a sacrificial material onto a base substrate in a predetermined pattern which is to be imparted onto products manufactured with the belt. The sacrificial material is deposited in droplets in a controlled manner so as to control the x, y, z dimension of the material deposited and preferably has having an average diameter of 10μ (10 microns) or more. A polymeric resin material is then deposited on the base substrate in all areas except those on which the sacrificial material has previously been applied. The polymeric resin material is then set by means appropriate to its composition, and the sacrificial material removed. Optionally, the polymeric resin material may then be abraded to provide the belt with a uniform thickness, and a smooth, macroscopically monoplanar surface.
