摘要:
A multi-ply flushable wipe includes a ply having first and second exterior layers and a middle layer disposed therebetween. Each of the exterior layers includes at least 50% by weight natural fibers. When foam-formed, the middle layer includes at least 25% by weight natural fibers. In embodiments, the middle layer may include at least 75% by weight natural fibers. The middle layer also includes synthetic fibers that have a length within the range of 1 mm and 20 mm. The wipe may have a length weight weighted average fiber length of less than 4 mm and a wet CD strength of greater than 20 N/m. Each ply of the wipe may be formed by wetlaying the first and second exterior layers and a foam formed middle layer to form a web, imprinting the web with a structured fabric, and drying the web. The plies are then attached using a binder.

A method of manufacturing an absorbent sanitary paper product having a machine direction, a cross-machine direction orthogonal and co-planar thereto, and a Z-direction orthogonal to both the machine- and cross-machine directions is disclosed. The method provides the steps of: providing a first and second network of fibers each having opposing first and second sides where each fiber of the first network of fibers has a longitudinal axis generally disposed within the plane comprising the machine- and cross-machine-directions; applying a first bonding layer to one of the first and second sides of the first network of fibers; applying a first second network of fibers to the first bonding layer; and, placing the first and second network of fibers into face-to-face contacting engagement.

摘要:
The present disclosure provides a multi-ply tissue product, also referred to herein as a tissue laminate, wherein the plies are adhesively adjoined by the zoned application of an adhesive. The zoned application of adhesive results in plies being adhesively joined by two or more longitudinally oriented strips of adhesive adjacent to the lateral edges of the ply. The resulting adhesively joined tissue has relatively high degrees of ply attachment, yet has relatively low stiffness.
摘要:
A manufacturing method of a security paper material, in particular for labelling and packaging, comprising the steps of forming a paper sheet from a wet cellulose fiber pulp and providing the paper sheet with electronic chips; the chips are introduced into the paper sheet being formed during the transformation step of the pulp into paper and are deposited directly onto the wet pulp and at least partially embedded in the pulp. Optionally, an auxiliary paper sheet is coupled to the paper sheet provided with the chips so that the chips are incorporated between the two sheets.
摘要:
The invention relates to a value document having an at least partially embedded security element, wherein the value document consists of a security paper having two or more layers of identical or different materials, and wherein the security element is designed as a transfer element and is applied to an internal surface of one of the layers of the security paper and is at least partially covered by at least one further layer of the multilayer security paper.
摘要:
A method for preparing composite structure self-assemblies. Structural segments are formed, which connect to each other through binder material. The structural segments are combined with the binder material to produce structural segments having the binder adhered thereto. The structural segments are combined to a form a composite structure through self-assembly, where the structural segments join to each other through said binder.
