description PROBLEM TO BE SOLVED: To provide a very silent intake duct pipe, which is highly soft without buckling due to bending, and absorbs intake noise generated inside the duct pipe. SOLUTION: This duct pipe is composed of a tubular woven fabric 4 made by weaving a plurality of warps 2 arranged annularly and extending in an longitudinal direction and wefts 3 crossing with the warps 2 and extending in a peripheral direction into a tubular form. The wefts 3 are made by alternately arranging first wefts 3a of a rigid linear element and second wefts 3b of a soft natural or synthetic fiber yarn. It is preferable that the second wefts 3b are stretchable yarns like synthetic fiber crimped yarn. COPYRIGHT: (C)2003,JPO
