Claims6
A jacket hose which is formed by providing a lining layer on an inside surface of a cylindrical jacket comprising a warp and a weft which are woven into twill, wherein a direction of a twill line formed by the warp woven continuously over the weft is substantially aligned with a central axis of the hose, or forms an angle of less than 10° to the central axis of the hose, and portions of the lining layer that are brought into contact with the twill lines constitute linear projecting rims projecting towards the inside of the hose, the linear projecting rims being arranged at an angle of less than 10° to the central axis of the hose.
A suction hose which is formed by providing a lining layer at least on an inside surface of a cylindrical jacket comprising a warp and a weft which are woven into twill, wherein a direction of a twill line formed by the warp woven continuously over the weft is substantially aligned with a central axis of the hose, or forms an angle of 10° to the central axis of the hose, and portions of the lining layer that are brought into contact with the twill lines constitute linear projecting rims projecting towards the inside of the hose, the linear projecting rims being arranged at an angle of less than 10° to the central axis of the hose.
