摘要:
The energy efficiency of a primary drying papermaking process is improved by the use of auxiliary dryers to dry the wet tissue webs to a final moisture of about 5% or less and adjust the CD moisture profiles of the wet and partially-dried tissue webs.

The energy efficiency of a throughdrying papermaking process is improved by recycling exhaust air from one or more throughdryers to further heat the web at various places in the process.
摘要:
The present invention provides tissue products having increased CD stretch, which may be manufactured using a process in which the nascent web is subjected to two distinct rush transfers. The first rush transfer occurs when the web is transferred from the forming fabric to the transfer fabric, i.e., the “first position,” and the second occurs when the web is transferred from the transfer fabric to the through-air drying fabric (TAD) fabric, i.e., the “second position.” The overall speed differential between the forming fabric and the TAD fabric may be, for example, from about 10 to about 50 percent, with the amount of rush transfer being divided between the first and second position in a manner sufficient to achieve the desired CD stretch and other sheet properties.

The intrinsic tissue sheet properties of tissue sheets wound into a parent roll during manufacturing can be purposely varied in order to provide a z-directional gradient within the parent roll. For example, the moisture content of the tissue sheet can be made lower in the core region of the parent roll and greater in the outer region of the parent roll. Such gradients can ultimately provide more uniformity of the intrinsic property within the final tissue product.

Tissue products are disclosed containing an additive composition. The additive composition, for instance, comprises an aqueous dispersion containing an alpha-olefin polymer, an ethylene-carboxylic acid copolymer, or mixtures thereof. The alpha-olefin polymer may comprise an interpolymer of ethylene and octene, while the ethylene-carboxylic acid copolymer may comprise ethylene-acrylic acid copolymer. The additive composition may also contain a dispersing agent, such as a fatty acid. The additive composition may be incorporated into the tissue web as the web is being formed. Alternatively, the additive composition may be topically applied to the web in a post processing operation. For instance, in one embodiment, the additive composition may be applied to the web as a creping adhesive during a creping operation.

Bath tissue rolls are provided with indicia or a visual cue representing the number of sheets remaining on the roll so the user better knows in advance when the remaining number of sheets on the roll is getting low.
摘要:
The present invention is generally directed to paper products having great softness and strength and methods of making the paper products. The paper products are formed from one or more paper webs that can be made according to various methods. In one embodiment, the paper web is an uncreped through-air dried web. According to the present invention, at least one side of the paper web is treated with a bonding material according to a preselected pattern and creped from a creping surface. Through the process, a two-sided tissue web is formed having a smooth side and a textured side.

A fabric dewatering apparatus for use after a fabric cleansing apparatus in a paper machine including: an endless wicking substrate disposed for rotation about a dryer roll; the endless wicking substrate and the fabric brought into surface contact as the fabric traverses at least a portion of the dryer roll's circumference; and a wicking substrate dewatering apparatus disposed along the wicking substrate's travel path after the dryer roll.
