Embodiment Construction

[0019] A preferred embodiment of the invention will be described in the context of a forming fabric for a paper machine. It should be noted, however, that the invention is applicable to fabrics used on other sections of a paper machine, and to fabrics used in other industrial installations where the smoothness, planarity and controlled permeability and Breathability is very important. Examples of other fabric types suitable for use in the present invention include paper machine press fabrics, paper machine dryer fabrics, through-air drying fabrics, and pulp forming fabrics. Another example is fabrics used in papermaking related processes such as slurry filters and chemical washing machines. Examples of other fabric types suitable for use in the present invention are engineered fabrics, such as those used in the manufacture of nonwovens by wet-laid, dry-laid, meltblown and / or spunbond methods.

[0020] Furthermore, the invention is generally described in terms of calendered "...

Abstract

A smoothed and durable industrial process fabric and method for producing such a fabric. The fabric may be used as a papermaker's fabric, other industrial process and / or engineered fabric. In any case, the fabric is processed using a device comprising at least two smooth rolls which form a pressure nip, such as a calender, such that at least some of the fabric components are permanently deformed. Preferably, at least one of the rolls is heated to a pre-selected temperature.

Description

technical field [0001] The present invention relates to endless fabrics, especially fabrics for use as industrial process fabrics for the following applications: manufacture of wet-laid products such as paper, cardboard, toilet paper and tissue products; wet-laid and dry-laid pulp for the manufacture of paper-related processes, such as those using slurry filters and chemical scrubbers, the manufacture of facial tissue and tissue products by through-air drying; Manufacture of nonwoven products made by spunbond and airlaid needlepunching. The term "industrial process fabrics" also includes, but is not limited to, all other papermaker's fabrics (forming, press and dryer fabrics) used to transport pulp throughout the stages of the papermaking process. Background technique [0002] During papermaking, a web of cellulose fibers is formed in the forming section of a paper machine by depositing a fiber slurry, which is an aqueous dispersion of cellulose fibers, onto a moving formin...
