PURPOSE: To obtain a tubular multilayer woven fabric reinforced in oblique direction, exhibiting large resistance to twist load and simultaneously capable of changing yarn density by controlling a tilting angle of warp.
CONSTITUTION: In a tubular multilayer woven fabric 1 obtained by superposing plural layers of tubular woven fabric 3 obtained by weaving plural warps 4 circularly arranged and wefts 5 crossing with the warps 4 and helically extending, plural layers of tubular woven fabrics 3 consist of warps 4 having same numbers and in one end of adjacent tubular woven fabric 3, warps 4 are mutually continued and simultaneously, in at least one layer of tubular woven fabric 3, the warp 4 is inclined to the length direction of the tubular woven fabric 3.
