Process and system for reorienting fibers in the foam forming process

摘要

A process for foaming a tissue or paper web is disclosed. A foamed suspension of fibers is deposited on the molded fabric and contacted with a gas stream before drying the web. For example, the web can contact the gas stream before dewatering the web. The gas flow can have a volumetric flow rate and / or velocity sufficient to rearrange the fibers in the web. In one embodiment, for example, gas flow may increase the caliper of the web, the stretch properties of the web, and / or the absorbency properties of the web. In one embodiment, the gas flow can be regularized to produce a web with a unique pattern.
