  • Stretchable fibers of polymers, spinnerets useful to form the fibers, and articles produced therefrom
    Patent number: 6548166
    Abstract: A stretchable synthetic polymer fiber comprising an axial core formed from an elastomeric polymer, and two or more wings attached to the core and formed from a non-elastomeric polymer, wherein preferably at least one of the wings is mechanically locked with the axial core. The fibers can be used to form garments, such as hosiery. A spinneret pack for producing such fibers is also provided.
    Type: Grant

  • Stretchable polymeric fibers and articles produced therefrom
    Publication number: 20020155290
    Abstract: A stretchable synthetic polymer fiber comprises an axial core formed from an elastomeric polymer, and two or more wings formed from a non-elastomeric polymer attached to the core. The fiber has a substantially radially symmetric cross-section. Such fibers can be used to form garments, such as hosiery.

  • Process for making modified alumina fibers
    Patent number: 5002906
    Abstract: Ceramic fibers of alumina modified with zirconia or hafnia derived from soluble salts of the metal are made by first polymerizing a mixture of alumina and aqueous aluminum chlorohydroxide before addition of the metal oxide precursor. Subsequent concentration and spinning steps are carried out at low temperatures.
