PURPOSE: To obtain the subject sufficiently flexible material having a functional substance in the interior, by packing an indeterminate functional substance into the interior of a thin cylindrical material having texture of hollow weave.

CONSTITUTION: A cylindrical material having texture of hollow weave is woven by plural warps W1... and one weft W2 in the peripheral direction, the warps W1... and the weft W2 are sufficiently thinned, weaving density is raised and a functional substance is not oozed when the functional substance M is packed into the interior. In order to pack the functional substance M, a method wherein a guide pipe is inserted into the interior of the cylindrical substance deeper than a cloth front and the indeterminate functional substance is extruded from the tip of the guide pipe is used.
