ABSTRACT:
A nonreinforced microfiber fabric is disclosed. The fabric has minimum grab tensile strength to weight ratio greater than 0.8N per gram per square meter and a minimum Elmendorf tear strength to weight ratio greater than 0.04N 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.
