  • Industrial fabric, and method of making thereof
    Patent number: 7617846
    Abstract: A papermakers's fabric which includes a system of CD yarns including a plurality of CD yarns and a system of MD yarns. The system of MD yarns further includes a first subsystem of MD yarns and a second subsystem of MD yarns, which are in a vertically stacked relationship with one another. The first subsystem of MD yarns includes sheds having at least two MD yarns with substantially similar aspect ratios. The aspect ratio of the MD yarns in the second subsystem of MD yarns is greater than that of the MD yarns in the first subsystem of MD yarns. All of the yarns the first and second subsystems of MD yarns are interwoven with the CD yarns of the CD yarn system in a repeat weave pattern. Seaming loops are formed using only MD yarns from the first subsystem of MD yarns.
