    Abstract: A method of manufacturing a disposable absorbent personal hygiene product, including a stretched elastic strand and a flat substrate portion, includes mixing a pressurized gas and hot melt adhesive to form a foamed adhesive and contact dispensing the foamed adhesive onto the stretched elastic strand by contacting the stretched elastic strand with the foamed adhesive. The foamed adhesive expands in volume on the stretched elastic strand and this expansion provides improved bond characteristics and/or reduced add on weight when the stretched elastic strand is secured to the flat substrate portion, thereby improving the personal hygiene product. The foamed adhesive may also be spread around on a periphery of the stretched elastic strand by wiping the foamed adhesive with a notch in a contact nozzle or by discharging air at the foamed adhesive in contact with the stretched elastic strand.

  • Patent number: 8821660
    Abstract: A method for manufacturing ecotypic artificial leather or leather-like includes the following steps: a first step of forming a surface layer; a second step of spray foaming which is to coat the partly cured surface layer with a reactive solvent-free multicomponent polymer using a multicomponent reaction injection molding device and a spray gun; a third step of once-molding roller pressing which is to press the substrate, foaming layer, surface layer and release paper together between the multicomponent polymer foaming stage and curing stage using a roller press device; and a fourth step of maturing and stripping, in which the substrate, foaming layer, surface layer and release paper are heated up, and then are cooled down while the release paper is removed. The production process utilizing the manufacturing method described in this invention is totally environmentally friendly. The physical and chemical properties of the product are excellent.

  • Patent number: 8758533
    Abstract: The invention relates to a process to foam a water-base adhesive wherein a gas is dissolved or generated under pressure in the water phase essentially without the formation of foam. To apply the adhesive in the form of foam, the pressurized adhesive is released through a valve onto a substrate at atmospheric pressure, whereby the dissolved gas separates as gas bubbles. The invention relates further to an apparatus for the implementation of said process comprising a pressure-tight container for the adhesive wherein an overpressure is provided through a first valve, and at the outlet of said container a drain valve is placed. The apparatus further comprises a pressure-tight acid vessel for the acid which is furnished with a second valve at its inlet The outlet of said vessel is connected through a third valve to the container.

  • Patent number: 8747587
    Abstract: A multi-layered material and a method for making the same are provided. The multi-layered material includes a first foamed layer, a substrate, a second foamed layer, and a surface layer. The first foamed layer has a plurality of first cells. The substrate is a fabric. The second foamed layer has a plurality of second cells. The foaming method of the second foamed layer is different from that of the first foamed layer. The size of the second cells is different from that of the first cells. The variation in size of the second cells is different from that of the first cells. The surface layer is disposed on the second foamed layer. Thus, when the multi-layered material is used as a surface cover of a ball, it can provide excellent resilience and control, and improve manufacturing efficiency.

  • Patent number: 8726956
    Abstract: A heat-expandable rubber layer is provided to an inner all of a pneumatic tire when the tire is in an uncured state. The rubber layer is expanded when the tire is in a vulcanized state. Once expanded, the rubber layer is capable of reducing rolling noises of the tire. The rubber layer includes an elastomer composition based on at least an elastomer, e.g., natural rubber or butyl rubber; a reinforcing filler, e.g., silica and/or carbon black; between 10 and 80 phr of a blowing agent, e.g., an azodicarbonamide compound; and between 10 and 50 phr of a hot-melt compound with a melting point between 70° C. and 150° C., e.g., urea. The combination of the blowing agent and the hot-melt compound, at recommended high contents, makes it possible to very greatly reduce an expansion ratio and therefore a thickness of the rubber layer once the pneumatic tire is vulcanized, without affecting noise absorption properties provided by the blowing agent.
