A method and system of using a polyolefin-based, hot melt adhesive improves creep performance of elastic strands adhered to another substrate. Some deflection, greater than 1°, of the exit angle formed by a line normal to the axis of a neutrally-positioned applicator and the elastic strand extending from the applicator is introduced. Preferably, deflection of the entrance angle is also introduced and a head tilt angle is also provided. The use of deflection improves creep performance or allows for a reduced amount of adhesive to be used to achieve the same or similar creep performance. The elastic strands may be used to form a leg cuff in personal care products, such as diapers, and the substrate to which they are applied could be a polyethylene film or non-woven materials.

A disposable wearable article includes an elastic film stretchable structure in which an elastic film is laminated between a first sheet layer and a second sheet layer. The first sheet layer and the second sheet layer are bonded to each other through holes passing through the elastic film with many bonded portions arranged at intervals. A region having the elastic film stretchable structure includes a stretchable region that elastically stretches and contracts together with the elastic film. The stretchable region includes a plurality of elastic films disposed so as to have an overlapping portion. The number of laminated layers of the elastic film in a region located in an intermediate portion of the stretchable region in an orthogonal direction (XD) orthogonal to a stretchable direction (ED) is different from that in each of second regions adjacent to both sides of the first region.

A building panel having a substrate and a layer arrangement, arranged on one side of the substrate. The layer arrangement having a surface layer and where the surface layer includes carpet fibres. At least the substrate at least partly includes a mechanical locking device for connecting at least two building panels. Where the substrate and the layer arrangement each includes a polymer of the same type of polymer.

A method to produce a panel. The method includes providing a core having a first surface, providing a surface layer including a substantially uncured amino resin, applying an hydrolysable adhesive on the first surface of the core and/or on a surface of the surface layer adapted to face the core, arranging the surface layer on the first surface of the core, pressing the surface layer to the core to form a panel by applying heat and pressure in a press, thereby adhering the surface layer to the core by the hydrolysable adhesive and curing the amino resin of the surface layer. Also such a panel.

A method and a mineral wool product include a multiple of lamellae, such as a sandwich panel core. The product includes a plurality of lamellae cut from a mineral wool web, and bonded together by applying an adhesive on the surfaces of two adjacent lamellae to form a web-like product, wherein the adhesive comprises at least one hydrocolloid.

The presently disclosed subject matter generally relates to recyclable insulation material for shipping containers, groceries bags, etc., machines for making the recyclable insulation material, and methods for the making the recyclable insulation material. In one aspect, a method of forming an insulation product may include forming a continuous sheet of paper into a plurality of flexible loops defining a plurality of air channels extending in a direction that is substantially perpendicular with a machine direction of the continuous sheet of paper. The method may also include immediately attaching a first layer of paper and a second layer of paper to the plurality of flexible loops as they are formed so that the continuous sheet of paper retains the plurality of flexible loops between the first layer and the second layer and that the plurality of flexible loops remain unattached with respect to one another.

An object of the present invention is to provide a glove in which a glove main body and a film are less likely to peel from each other even when a load, especially a torsional load, is applied. A glove according to an aspect of the present invention includes: a glove main body made of fibers; a film which covers at least a part of an outer face of the glove main body and contains a rubber or a resin as a principal component; and an adhesive portion which bonds the glove main body and the film together, wherein the adhesive portion includes: a pressure-sensitive adhesive layer in contact with the film; and an adhesive layer which is in contact with the glove main body and is constituted by a hot-melt adhesive.

Provided is an absorbent article which includes a top sheet having extruded protrusions and a second sheet bonded to the top sheet and has adequate softness, satisfactory appearance, and yet prevents wrinkles in the top sheet along the MD. The problem is solved by a method of producing an absorbent article including forming the extruded protrusions through embossing of non-woven fabric to be a top sheet transferred by being drawn from downstream of a production line; and then bonding the non-woven fabric and a material of a second sheet in a bonding pattern formed by aligning the material of the second sheet 40 with the back face of the non-woven fabric having extruded protrusions, forming rows of plurality of top-second bonded portions at intervals in the CD in regions between the extruded protrusions adjacent each other in the MD so as to be provided across the center positions of the regions in the CD, and compressing the non-woven fabric in areas between the top-second bonded portions in the rows in the CD without welding of the non-woven fabric and the material of the second sheet.

Hot melt adhesive composition comprising: —from 30% to 55% of a composition (A) consisting of 2 copolymers of propylene and ethylene (A1) and (A2), with Mw of less than 100,000 Da, wherein: —(A1) is an essentially amorphous copolymer, with a DSC melt enthalpy of 10 less than 30 J/g; —(A2) is a semicrystalline copolymer with a DSC melt enthalpy of more than 30 J/g; and —the ratio:weight of (A2)/weight of (A1) is from 0.2 to 1.5; —from 20% to 50% of a tackifying resin (B); and 1—from 2% to 25% of a plasticizer (C) consisting of a liquid polybutene oligomer. 2) Process of manufacturing an assembly product, preferably a disposable nonwoven absorbent article, implementing said hot melt adhesive composition.

A veneered element, including a substrate, a wood veneer layer having a first surface and a second surface, the first surface being opposite to the second surface, an adhesive layer adapted to adhere the first surface of the wood veneer layer to a surface of the substrate, wherein adhesive from the adhesive layer is present in a first portion of the wood veneer layer, extending from the first surface of the wood veneer layer into the wood veneer layer, and wherein the second surface of the wood veneer layer is substantially free from adhesive from the adhesive layer. Also, a method of producing such a veneered element).
