Abstract:
A method of making a twisted elongated yarn, said method comprising providing a first elongated yarn of polymer material of indeterminate length having a deformed outer surface and a non-uniform cross-section over its entire length, providing a second elongated yarn of polymer material of indeterminate length having a deformed outer surface and a non-uniform cross-section over its entire length, simultaneously heating continuously both said first and second elongated yarns by a common heat source having a temperature in the range of 200-375Â° F., said first and second elongated yarns being heated to the same predetermined temperature, and continually twisting said first and second elongated yarns together to form a twisted yarn therefrom, wherein said predetermined temperature is sufficient to cause said first and second elongated yarns to adhere to each other over intermittent portions about their deformed outer surface.
