  • Patent number: 4811428
    Abstract: A bib for children is fabricated of a thermally bonded laminate of vinyl film and polyester fabric materials. The laminate is provided with an embossed finish which is abrasion resistant and washable. A water based, non-leaching acrylic ink is applied to the embossed finish for ornamentation. The bid includes a body portion having interior vinyl and outer polyester sides, top and bottom peripheral edges, and side edges. First and second neck fastening members extend from the top peripheral edge and terminate at overlapping ends which include synthetic hook and loop fastener elements. The bib also includes a pocket formed by a panel which overlies and is thermally sealed to the body portion. A durable pocket construction is provided by employing reinforcing thermal seals to secure the pocket panel to the body portion.

  • Patent number: 4248685
    Abstract: Hydrocolloidal dispersions of random interpolymer compositions that have a capacity for absorbing water in amounts of from 10 to 125 times their own weight or greater and are also bacteriostatic are prepared by the polymerization in aqueous medium of a mixture of monomers comprising (1) up to about 90% by weight of an ester of an .alpha.,.beta.-olefinically unsaturated carboxylic acid and a monohydric or polyhydric alcohol having a terminal quaternary ammonium group and (2) at least one .alpha.,.beta.-olefinically unsaturated comonomer in the presence of a crosslinking agent comprising a difunctional monomer derived from an .alpha.,.beta.-olefinically unsaturated carboxylic acid. The interpolymer compositions can be used for binding or coating nonwoven fabrics including paper to improve water absorbency, or cast into a structurally self-supporting film.
