  • Nonwoven medical fabric
    Patent number: 4908163
    Abstract: A nonreinforced microfiber fabric is disclosed. The fabric has minimum grab tensile strength to weight ratio greater than 0.8 N per gram per square meter and a minimum Elmendorf tear strength to weight ratio greater than 0.04 N per gram per square meter. The fibers in the fabric have an average length greater than 10 centimeters and at least 80% of the fibers have a diameter of 7 microns or less. The fabric is made by thermally embossing a microfiber web which is made with a minimum of degradation to the polymer and employing high velocity secondary air to maintain air flow uniformity and fiber length.
    Type: Grant
    Filed: July 11, 1986
    Date of Patent: March 13, 1990
