  • Block copolymer based hot melt adhesive for bonding lotion coated substrates
    Patent number: 6531544
    Abstract: The present invention relates to using certain block copolymer based hot melt adhesive compositions for the assembly of disposable absorbent articles such as disposable diapers wherein the adhesive is in contact with an oil-based skin care ingredient, and the resulting disposable absorbent article. The adhesive is particularly useful for adhesively bonding elastic to nonwoven, and exhibits good stress resistance in the presence of lotion.

  • Fibers comprising water soluble polyamides and articles constructed therefrom
    Patent number: 5869596
    Abstract: This invention relates to a nonwoven web and fibers comprising a water soluble polyamide and articles constructed therefrom. The water soluble polyamide may be used alone or in combination with conventional thermoplastic web and fiber forming materials such as water insoluble polyethylene, polypropylene, polyester and polyamide. The water soluble polyamide may also be combined with biodegradable or selectively dispersible material to form nonwoven webs and fibers having various combinations of properties. Such water soluble webs and fibers have utility in the manufacture of disposable absorbent articles such as disposable diapers, feminine napkins, incontinent products and cellulosic articles such as tissues and towels, as well as for water soluble heat fusible webs for the textile industry.
