  • Solvent free aqueous polyurethane dispersions and shaped articles therefrom
    Patent number: 9346932
    Abstract: Novel aqueous polyurethane dispersions and shaped three dimensional articles formed therefrom are provided. The aqueous polyurethane dispersions are provided in solvent-free systems of a prepolymer comprising at least one polyether, polyester, or polycarbonate polyol, a mixture of MDI isomers, and a diol.

  • BONDED FABRIC CONSTRUCTIONS WITH STRETCHABILITY
    Publication number: 20120100351
    Abstract: Included are bonded laminate constructions that have a modulus which approaches the sum of the modulus of the individual components of the laminate. By reducing variation in the modulus, the stretch or elasticity of the bonded or laminated fabric or garment is maximized. The bonded laminates include a bonding component that may be an elastomeric film, an adhesive, or a combination of a film with adhesive.
