PROBLEM TO BE SOLVED: To provide a simple and practical method for manufacturing a trapping material by winding up a sheet material while controlling bulk density.
SOLUTION: When the sheet material is wound by n times so that a cylindrical space with a circular cross section having a diameter of R is formed in the center, a difference in level between steps is W
set . When a step at a position of start of winding up the sheet material is determined as a first step, the length of a n-th step is 0.9-1.1 times the length of circumference having a radius which is a distance from the center point of the cylindrical space to the center position of the thickness of a n-th layer from the most internal layer of the trapping material (the first layer), and the total length from the first step to the n-th step is 0.8-1.2 times the total length of the circumferences of the first layer to the n-th layer. (N: a natural number of 2 or more, n: a natural number of 1 or more, Wset [mm]: a set value of the thickness per one layer of a trapping material).COPYRIGHT: (C)2008,JPO&INPIT
