摘要:
A method and product is disclosed to obtain sheets with increased cross-machine stretch. The method involves the use of a cross-machine stretchable fabric upon which a wet web of paper is placed. The method results in a product having increased cross-machine stretch.
摘要:
A method for making uncreped throughdried tissues is disclosed in which the dried tissue sheet is fully supported by a fabric up to the reel. This method eliminates the open draw between the throughdryer and the reel and thereby eliminates sheet breaks normally associated with such open draws. In addition, the machine direction strength of the sheet can be reduced since the added strength is not needed to traverse the open draw normally present in current processes. Reducing the MD strength in turn enables the production of more square, less stiff sheet, which improves the tactile properties of the product.

Wiping products, such as 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 base web by being combined with the fibers that are used to form the web. Alternatively, the additive composition may be topically applied to the web after the web has been formed. The additive composition can improve various properties of the wiping product. For instance, in one embodiment, the additive composition can reduce lint and increase softness.
摘要:
Soft throughdried tissues, which are sufficiently soft to serve as premium bathroom tissues, can be made without the use of a Yankee dryer. The typical Yankee functions of building machine direction and cross-machine direction stretch are replaced by a wet end rush transfer and the throughdrying fabric design, respectively. It is particularly advantageous to form the tissue with chemimechanically treated fibers in at least one layer. The resulting tissues have high bulk (about 6 cubic centimeters per gram or greater) and low stiffness.

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.
