  • Patent number: 6436508
    Abstract: The present invention relates to absorbent article such as sanitary napkins and panty liners comprising a topsheet, absorbent core, and backsheet which are breathable by the incorporation of a breathable backsheet and have a reduced tendency to exhibit garment wet through. The backsheet comprises at least one air permeable layer such as an apertured formed film or fibrous layer which is applied and preferably coated with a non-soluble, liquid swellabe material, such as polyvinyl alcohol. Upon contact with fluid discharge, the material swells and closes the apertures of the layer, thereby reducing air permeability and preventing the passage of liquid through the layer and thus through the backsheet onto the garment of the wearer of the article.

  • Patent number: 6248202
    Abstract: A process for manufacturing individual layered structures and the structures themselves. A continuous layered structure is provided. The continuous layered structure has designated cutting regions and includes a particulate material between the layers. At least one of the layers is permeable to liquids. A thermoplastic material in liquid state is applied to the continuous layered structure over at least part of the designated cutting regions to provide the designated cutting regions with a joining means. The thermoplastic material is made of natural or synthetic polymers, or mixtures thereof. The thermoplastic material has a softening point, as measured according to the ASTM Method E 28-67, lower than 120° C.; a viscosity at 130° C. lower than 0.05 Pa.s; and a temperature range in which the viscosity changes between 0.05 Pa.s and 0.35 Pa.s which is greater than 5° C. The thermoplastic material is allowed to set.

  • Patent number: 6211263
    Abstract: The present invention relates to a combination of a substrate with combinations for attachment to the skin. In particular the present invention relates to a combination of a substrate which can be employed for attachment to the skin of articles such as protective articles, clothing, prosthesis, heat wraps, pads, and/or packs, cold wraps hearing, protective face masks, ornamental articles or eye wear, or also of functional articles such as cosmetic or pharmaceutical delivery articles that provide a substance to the skin. The combination provides secure attachment and is pleasing to the skin upon application, yet causes no discomfort upon removal. This is achieved by selecting the chemical composition and heological characteristics of the combinations and the physical characteristics of the substrate on which the combination is applied.

  • Patent number: 6149640
    Abstract: Disclosed are flexible plastic tapes each having at least one rounded edge, a method for forming the rounded edge by the application of heat, and an absorbent article provided with such tapes. The edges are rounded to reduce their sharpness in order to reduce the risk of irritation or injury to a wearer of the absorbent article and/or to any person coming into contact with the tapes. The tapes have a thickness not greater than that at which the edge would be sharp if it were not rounded. The tapes are relatively stiff and formed from a plastic material such as polypropylene or polypropylene copolymer.

  • Patent number: 5969025
    Abstract: The invention provides a water-based adhesive composition comprising a blend of adhesive polymers in an aqueous system, characterized in that the blend of adhesive polymers is: 20-60% by weight of an acrylic polymer having a polarity balance expressed as water absorption according to DIN 53495 of 3 to 20%; and correspondingly 40-80% by weight of a compatible tackifying resin having a degree of hydrophobicity measured as the contact angle between a dried film of the resin and a drop of distilled water of not less than 60.degree.; the percentages being based on the total of acrylic polymer plus tackifying resin expressed as dry solids. The composition shows good bond retention when wet and can be used for bonding polar substrates such as cellulose and non-polar substrates such as polyolefin. When used to bond a water absorbing substrate such as cellulose, the adhesive should have a viscosity of 200 mPas or less.
