A universal barrier system includes universal barrier components that may be assembled together to shield floors and walls from moisture and provide a thermal break in an operational area of the universal barrier component. A lap zone of the universal barrier component may allow universal barrier components to be assembled and installed to protect floors, walls, ceilings, footings and the like from moisture and heat gain or loss by minimizing the need for tapes and other joining methods. The universal barrier system may also act as a sound deadening material. The operational area and lap zone of the universal barrier component may be disposed on a vapor block layer to provide some rigidity. The operational area of the universal barrier component may include a thermal break disposed upon the vapor block layer. The thermal break may include an outer protective layer.

The present invention covers a non-woven fabric for laminate on a polyethylene layer, such that a. it is comprised by a mixture of polypropylene hydrophobic and hydrophilic fibers; b. it is manufactured by means of a carding process followed by thermal bonding c. during the thermal bonding is engraved in at least 15% of its area d. has a minimum base weight of 13 gr/m.sup.2.

Radiation shielding performs a range of functions determined by the type and number of layers of materials used, thickness, weight, and structural support afforded by the radiation shielding. A radiation shield laminate stack may be constructed consisting of a plurality of layers of ultra-high molecular weight (UHMW) polyethylene, polyethylene film, and carbon fiber, which is held together with an epoxy. The carbon fiber lay may be coated with nanoparticles of Boron (B) or Boron Nitride (BN), Boron Oxide (B.sub.2O.sub.3) or Boron Carbide (B.sub.4C) or a combination thereof to increase the shielding properties of the laminate stack. The radiation shield is lighter than aluminum, structurally sound, and thus may be used in the space environment to effectively block Galactic Cosmic Rays, atomic oxygen and UV radiation.

A strengthened polyethylene tubular member, where the polyethylene tubular member has an outer surface, a circumference, a wall thickness, an area to be strengthened, and the outer surface of the polyethylene tubular member contains polyethylene. The strengthened polyethylene tubular member contains a fabric layer wrapped around the circumference of the tubular member at least two full rotations and covering the area to be strengthened. The fabric layer contains a plurality of interwoven tape elements with a base layer of a strain oriented olefin polymer disposed between covering layers of a heat fusible olefin polymer. The tape elements within the fabric layer are bonded together and the tape elements adjacent the tubular member are bonded to the tubular member.

A method for preparing an article includes at least a first component of a polyolefin in conjunction with a second component of a polymer made by ring-opening metathesis polymerisation of norbornene type monomers. The method includes pre-treating a surface of the first component, applying a ring-opening metathesis polymerisable mixture of norbornene type monomers and a catalyst to the surface, and curing the ring-opening metathesis polymerisable mixture in contact with the surface, wherein the ring-opening metathesis polymerisable mixture has a .sub.1000 at 30 C. of more than 9 sec. Articles such as a pipe line field joint or a protective element for a concrete tunnel lining element can be made using the method.

A manufacturing method uses a main body piece formed of an elastic fabric material and having a first portion having a first end, a second portion having a second end opposite the first end, and two side ends extending between the first and second ends. A bonding material is placed in contact with the first and/or second portions, arranged in lines extending in a direction between the first and second ends. The lines are spaced from each other in a second direction extending between the side ends. The main body piece is folded so that the first portion confronts the second portion, defining a fold line, where the bonding material is positioned between the first and second portions. The folded main body piece is then heat pressed and bent so the side ends are connected together to form a band having a tubular body defining a central passage.

A decorative laminate film including at least an inner film and an outer film, on which a printed pattern and a protruded portion that protrudes toward the outer film side are formed. The protruded portion is positioned on or in the vicinity of the printed pattern, and the outline of the printed pattern is blurred. The printed pattern and the protruded portion can be aligned easily, thereby providing excellent productivity. Even if the protruded portion is slightly misaligned, the design does not deteriorate, and the decorative laminate film has a favorable design due to gradation effect imparted by the protruded portion and the adjacent printed pattern.

A seat for vehicles including a seat cushion, a seat back, and a head rest has the following arrangement to ensure that a surface member can be relatively easily but positively removed from a urethane pad if a foam molding defect is found in the urethane pad in integral molding of the urethane pad and the surface member. In the seat for vehicles, any one of the seat cushion, seat back, and head rest has a configuration where a surface of the urethane pad is covered with the surface member. The urethane pad and the surface member are partially bonded together by integral molding.

Provided is a method for manufacturing a fishing net formed from a plastic net that can be handled by winding or folding although the net has plastic rigidity. The fishing net is manufactured by (1) a step of preparing a multifilament yarn formed by bundling a plurality of core-sheath type composite filaments, in each of which a core component is made of polyethylene terephthalate and a sheath component is made of polyolefin, (2) a step of preparing a yarn thread obtained by paralleling a plurality of the multifilament yarns, (3) a step of twisting or braiding four yarn threads 11, 12, 13, 14 to obtain a net constructed with strands 1 and intersections 2, (4) a step of heat-treating the net under without pressure to melt the sheath component of the yarn threads 11, 12, 13, 14 constituting the strands 1 and the intersections 2, followed by solidifying, thus obtaining a plastic net, and (5) a step of forming the fishing net using the plastic net.

The present invention is directed to a side-sealed open mesh fabric bag having one or more multi-layer seam structures. At least one side seam of the bag comprises a plurality of folded layers of the bag's fabric bonded together within a seam structure by a plurality of seal portions. At least one of those seal portions is a sacrificial seal configured to at least partially give from the seam structure, whilst one or more other seal portions of the seam structure remain intact. The sacrificial seal provides the bag with volumetric flexibility, whilst the remaining seam structure provides an improved seam strength.
