  • Publication number: 20150031261
    Abstract: A technique for forming fibers (e.g., nanofibers, microfibers, etc.) from an aqueous spinning solution is provided. Through careful control over the nature and relative concentration of the components in the solution, fibers can be formed that remain relatively water resistant. To help accomplish these unique features, a pH-sensitive polymer is employed in the spinning solution that is generally soluble in water at a certain pH value, yet generally insoluble in water at a different pH value. This property allows for selective adjustment of the pH both before and after spinning to control the water-solubility of the polymer as desired.

  • Publication number: 20150017868
    Abstract: A hot melt adhesive composed of an ethylene vinyl acetate copolymer, a hydrogenated styrenic block copolymer, a tackifying resin, and a liquid plasticizer. The preferred ethylene vinyl acetate copolymer has a vinyl acetate content between 8 and 28 percent by weight, and the preferred hydrogenated styrenic block copolymer is a styrene-ethylene-butylene-styrene having about 30% styrene content and essentially no diblock. The hot melt gives excellent peel strength when used as a construction adhesive for disposable nonwoven articles. It can also be formulated to exhibit very low bleed through and blocking characteristics when used on low basis weight nonwoven fabrics.

  • Patent number: 8900692
    Abstract: The forging-reinforced composite constructed of a plurality of different kinds of materials, which have compatible polymers comprising crystalline and glass phases at room temperature for the matrices, is a composite, wherein, by being forged in a layer-separated state in which each of the different kinds of materials forms micron-sized fibrous layers that crossed and intermingled three-dimensionally with each other and the arrangement of the crystals in the crystalline phases configuring the matrices having a disordered orientation without anisotropy in a variety of directions, the inherent-properties of the material of each layer are complementarily reinforced. A mixed nonwoven fabric wherein microfibers are crossed and intermingled two- or three-dimensionally with each other is manufactured and heated under pressure at or above the melting point of the polymers to manufacture compact blocks wherein the microfibers are welded. Then, the compact blocks are forged at a crystallization temperature.
