  • Terry fabric and method for weaving same
    Patent number: 7111648
    Abstract: A terry fabric comprises a plurality of repeat units of interwoven warp and weft threads. Each of the repeat units comprises a set of ground warp threads, a set of pile warp threads, and a set of weft threads. The ground warp threads are woven tightly with the weft threads to form a substrate, and the pile warp threads are loosely interwoven with the weft threads to form pile loops. At least two adjacent weft threads are interwoven with the ground warp threads and the pile warp threads in an identical pattern (typically in a single machine cycle). In this configuration, fabrics with different properties can be producing in similar manufacturing duration, particularly if weft threads of different thread weight are employed.
