摘要： Disclosed is a non-nested, two-ply, absorbent fibrous sheet material consisting of two webs which each have a plurality of crests and depressions on its surface facing the other web. The crests on each web are positioned between the crests of the other web and are spaced from the depressions of the other web to leave spaces in the sheet material for increased absorbency and bulk. The two webs are joined together at locations intermediate the crests and depressions of at least one of the webs, preferably by mechanical welding in a manner which produces perforations in the sheet material. Also disclosed is the method and apparatus for making the two-ply sheet material.

摘要： The present invention is generally directed to facial tissues having great softness and strength. The facial tissues are made from a multi-layered paper web containing a middle layer of eucalyptus fibers either alone or in combination with polyester fibers. The paper web is made with a debonding agent for producing a web having reduced levels of fiber bonding. Once formed, the paper web is treated on each side with a bonding agent in a preselected pattern. Both sides of the paper web are also creped. In order to create a smooth low friction surface, the paper web is fed through a calendering machine and treated with a friction reducing composition and subsequently dried.

摘要： A method of making a bonded and creped type absorbent paper web that has improved bulk to peel strength characteristics includes steps of (a) printing a low density pattern of a bonding material onto a first and a second side of a paper web; and (b) in no particular sequence with respect to step (a), printing a high density pattern of a bonding material onto the first side of the paper web. Steps (a) and (b) are performed so that the high density pattern of bonding material penetrates into the paper web by a distance that is about 166 to about 470 percent of the distance by which the low density pattern of bonding material penetrates into the web. This results in a web that has superior bulk and peel strength characteristics. Another characteristic of the product is that it has a visible depression pattern in one surface, but not the other surface, which creates an attractive aesthetic effect and has functional benefits as well.

摘要： The present invention provides a multi-layered wiping product that maintains desired characteristics of softness, strength, stretchability, absorbency, and the like. The wiping product is formed from a process using a multi-layered paper web, printing a bonding agent on both of its outer surfaces, pressing the web so it adheres tightly to a creping surface and lightly to a presser roll, and then creping one of its surfaces.

摘要： An absorbent printed paper web and methods for making the printed web, the web having a visually discernible larger pattern, which can be a logo, on at least one surface formed essentially only of a paper web and a strengthening, colored bonding material. The printed web having the larger pattern can be made using the same bonding material and process used to print the background pattern. A double recrepe process using an improved Gravure roll may be used to print both logo and background. One method includes using a Gravure roll having deep depressions for printing a geometric background pattern, which can be a cross hatch pattern defining unprinting surface areas between the repeating deep depressions. The Gravure roll can also have shallow depressions in the reverse image of a logo to be printed, where the shallow depressions can have contiguous logo areas much larger than the size of the repeating deep depressions or unprinting surface areas in the background pattern. The shallowly printed regions add strength, and due to interaction with the creping roll and blade, also add bulk and softness to the finished web. The printed web can be printed with a Latex bonding material on one or both web surfaces, not requiring further web printing and compression on a surface after creping. The resulting printed web can carry a product or service logo or trademark, while being strengthened and expanded by the bonding material which also carries the logo or trademark.
摘要翻译： 一种吸收性打印纸幅和用于制造印刷幅材的方法，所述幅材在至少一个基本上仅由纸幅形成的表面和加强着色的粘合材料的表面上具有视觉上可辨别的较大图案，其可以是标识，其可以是标识。 可以使用与印刷背景图案相同的粘合材料和方法制造具有较大图案的印刷幅材。 使用改进的凹版辊的双重重现过程可用于打印徽标和背景。 一种方法包括使用具有深度凹陷的凹版辊来印刷几何背景图案，该几何背景图案可以是限定重复深度凹陷之间的未打印表面积的交叉影线图案。 凹版辊也可以在要打印的标识的反向图像中具有浅凹陷，其中浅凹陷可以具有比背景图案中的重复深凹陷或未打印表面区域的尺寸更大的连续标志区域。 浅层印刷区域增加强度，并且由于与起皱辊和刀片的相互作用，还对成品网增加了大量和柔软性。 印刷的卷筒纸可以在一个或两个卷筒纸表面上印有乳胶粘合材料，在起皱后不需要在表面上进一步的纸幅印刷和压缩。 所得到的印刷网可以携带产品或服务标识或商标，同时通过还带有徽标或商标的粘合材料进行加强和扩展。
