ABSTRACT:
A drying wire provided with an independent top fabric and bottom fabric. The bottom fabric is woven from longitudinal and cross direction monofilament yarns. The top fabric is woven from longitudinal yarns and shapeable cross direction yarns. The shapeable yarns make the structure of the top fabric denser and increase the contact surface area and the number of contact points. On the other hand, the bottom fabric is also smooth, wherefore it has good aerodynamic properties.
