Forming fabric with extended surface

a technology of fabric and extended surface, applied in the field of forming fabric and extended surface fabric, can solve the problems of unpressed quality of protected fibers, within the body of structured fabrics, and achieve the effects of less capital investment, less machine equipment, and reduced quality, bulk, volume and absorbency capacity

AI Technical Summary

Benefits of technology

The solution enables the production of high-quality tissue with consistent fiber distribution and enhanced absorbency, maintaining production speed while reducing capital investment, operational complexity, and consumable costs, by forming and dewatering the sheet between structured and dewatering fabrics, ensuring fibers remain unpressed for quality and bulk retention.

Problems solved by technology

Against the Yankee dryer, only the fibers at the knuckle area of the structured fabric will be pressed, and the protected fibers, within the body of the structured fabric, remain unpressed for quality.

Embodiment Construction

[0047]Referring now to the drawings, and more particularly to FIG. 1, there is shown fibrous web machine 20 including headbox 22 that discharges fibrous slurry 24 between forming fabric 26 and structured fabric 28. Rollers 30 and 32 direct fabric 26 in such a manner that tension is applied against slurry 24 and structured fabric 28. Structured fabric 28 is supported by forming roll 34 which rotates with a surface speed that matches the speed of structured fabric 28 and forming fabric 26. Structured fabric 28 has peaks 28a and valleys 28b, which give a corresponding structure to web 38 formed thereon. Structured fabric 28 travels in direction W and, as moisture M is driven from fibrous slurry 24, structured fibrous web 38 takes form. Moisture M that leaves slurry 24 travels through forming fabric 26 and is collected in save-all 36. Fibers in fibrous slurry 24 collect predominately in valleys 28b as web 38 takes form.

[0048]Structured fabric 28 includes warp and weft yarns interwoven o...

Abstract

A method of forming a structured fibrous web including the steps of supplying a fiber slurry to a nip, the nip being formed by a structured fabric and a forming fabric; dewatering the fiber slurry through the forming fabric to create a web; retaining the web with the structured fabric through at least one dewatering process, the forming fabric including a woven fabric having a paper side and a roll side, the paper side having a paper side surface and said roll side having a roll side surface; and providing a polymer material deposit extending above the paper side surface, the polymer material deposit having at least one of a random pattern, a random motif, a pseudo-random pattern, a pseudo-random motif, a predetermined pattern and a predetermined motif.
