Disclosed herein are systems, devices, and method for forming self-adhesive single or multilayer fibrous media.

A metal-carbon fiber reinforced plastic composite comprising a metal member of a ferrous material or ferrous alloy, a resin layer provided on at least one surface of the metal member and including a thermoplastic resin, and carbon fiber reinforced plastic provided on a surface of the resin layer and including a carbon fiber material and a matrix resin having thermoplasticity, a glass transition point Tg1 or melting point Tm1 of the resin layer being higher than a glass transition point Tg2 or melting point Tm2 of the carbon fiber reinforced plastic, in which metal-carbon fiber reinforced plastic composite, an AC impedance at a frequency 1 Hz when immersing the metal-carbon fiber reinforced plastic composite in an aqueous solution containing sodium chloride in 5 mass % is 1?10.sup.7? or more.

A process for spraying back-adhesive of a CMP pad, includes steps of: horizontally placing an underlayment on middle portions of an upper conveying roller and a lower conveying roller of a hot melt machine for feeding; providing an upper layer glue-coated paper closely attached with an upper surface of the underlayment on the upper conveying roller, providing a lower layer glue-coated paper closely attached with a lower surface of the underlayment on the lower conveying roller; spraying hot melt adhesive on an upper surface of the lower layer glue-coated paper via an ejector nozzle of the hot melt machine; wherein the upper layer glue-coated paper, the underlayment and the lower layer glue-coated paper are transmitted and adhered with each other on the upper conveying roller and the lower conveying roller.

A water comprising, two component polyurethane dispersion adhesive comprising an anionic polyester polyurethane resin and a solvent-free liquid aliphatic polyisocyanate cross-linker. The dispersion can be reactivated one or more times for edge bonding a flexible sheet material onto a substrate having a main surface, a peripheral surface and an edge connecting the main surface and the peripheral surface.

Method for bonding a thermoplastic piping system (1) without the use of solvent-based adhesives, the piping system (1) comprising at least one first pipe or fitting part (11), and at least one second pipe or fitting part (12), which comprises the steps of i) applying a cyanoacrylate adhesive (2) onto at least one surface of the at least one first pipe or fitting part (11), or at least one second pipe or fitting part (12), ii) inserting together the at least one first pipe or fitting part (11), and the at least one second pipe or fitting part (12) before an open time lapses, iii) removing the excess of cyanoacrylate adhesive (2), iv) allowing the adhesive to cure. Associated adhesive for bonding a thermoplastic piping system (1) without the use of solvents, comprising a cyanoacrylate monomer (21), a polymerization inhibitor, a viscosity thickener, and a curing speed adjusting catalyst.

A product made by a method for bonding fibers that includes providing a first fiber layer and a second fiber layer positioned below the first fiber layer to bond the first fiber layer with the second fiber layer. The method may also include providing a first additive layer. The first additive layer is located between the first fiber layer and the second fiber layer. Then, the method may further include activating the first additive layer by directing energy at the first additive layer.

A method for producing a multilayer member having a first member containing a crystallizable thermoplastic resin, an adhesion layer, and a second member includes performing a dry treatment on a surface of the first member containing a crystallizable thermoplastic resin so as to satisfy conditions A and B, applying an adhesive to the surface of the first member to form an adhesive layer on the surface, and adhering the second member to the adhesive layer. (A) The ultimate temperature of the first member is lower than the peak temperature of endothermic peak obtained by DSC of the crystallizable thermoplastic resin. (B) The high temperature holding time of the first member is less than 3.0 seconds, which is when the first member is continuously held at a temperature not lower than a temperature at the starting point of the endothermic peak obtained by DSC of the crystallizable thermoplastic resin.

A pocketed spring assembly comprises a plurality of parallel strings of individually pocketed springs. Each string is joined to at least one adjacent string. Each string has first and second opposed plies of fabric and a plurality of pockets formed along a length of the string by transverse segmented seams joining the plies. Gaps between the segments of the seams allow air to pass into and out of the pockets despite the fabric being impermeable to airflow through the fabric. The fabric has at least four layers. The size of the gaps determines the firmness or feel of the pocketed spring assembly or portion thereof.

A plastics molding process is provided in which a first (2) and a second plastic part (3) are molded such that a contact surface is formed between the two parts. The first part (2) is molded firstly and, while at least the contact surface is still in a liquid or plastic state, an attachment promoting powder (16) that is compatible with, and has the characteristic of attaching to, the plastic of the first part (2), is applied to it. Thereafter, the second part (3) is molded so as to contact the first part at the contact surfaces such that as it solidifies, it attaches to the attachment promoting powder (16) and thereby to the first part (2). The second part (3) may be a plastic foam filling for a hollow first part (2). The attachment promoting powder (16) may be a suitable grade of diatomaceous earth or a natural or synthetic equivalent.

A die coater 10 as a coating member directly applies an adhesive resin G to a joining portion of a workpiece W by a predetermined width while a holding table 1 holding the workpiece W placed thereon moves. A reinforcing substrate T supplied from an original master roll is joined to the resin G applied to the workpiece W while being pressed by a joining roller 15, and the reinforcing substrate T is cut by a predetermined length. That is, an adhesive sheet is directly formed on the workpiece W.
