It is estimated that 1.67 billions of tires have been made in the United States since the advent of the motorcar and truck. There have been many types of tire constructions, tread designs, and manufacturing methods; however, now practically all tires have the same general construction design. Processing of both the fabric body and the rubber stocks has improved greatly. These improvements have resulted in a better tire with longer mileage capacity and much better service life. This paper deals specifically with cord fabrics as used in passenger and truck tires and summarizes the general processing requirements and techniques as carried on in the United States. Emphasis is placed on nylon fabric, principally because of the present tendencies of the American manufacturers to accept nylon-cord fabric as being superior to cotton and rayon for many important tire-cord requirements.
