<p><P>PROBLEM TO BE SOLVED: To provide a multilayer hose with an innermost layer hose spirally formed of a resin, having less torsion while maintaining flexibility. <P>SOLUTION: The innermost layer spiral hose 12 of the multilayer hose 10 is formed of a resin such as PPS into a clockwise spiral shape. A reinforcing layer 20 is laid between an intermediate layer 14 formed of a resin on the outer periphery of the spiral hose 12 and an outermost layer 16. The reinforcing layer 20 consists of a clockwise reinforcing layer 21 having a resin fiber reinforcing yarn HS spirally wound in the same (clockwise) direction as the spiral direction of the spiral hose 12 and a counterclockwise reinforcing layer 22 having a resin fiber reinforcing yarn HS spirally wound in the opposite (counterclockwise) direction to the spiral direction of the spiral hose 12. In both reinforcing layers, the weaving angles of the resin fiber reinforcing yarns are both 54°or smaller. Additionally, the counterclockwise reinforcing layer 22 has a weaving angle of about 1-5°smaller than the clockwise reinforcing layer 21. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
