MANUFACTURING METHOD OF BELT-LIKE STRING MEMBER, BELT-LIKE STRING MEMBER, AGENT CONTROLLED RELEASE MATERIAL USING BELT-LIKE STRING MEMBER, AND AGENT CONTROLLED RELEASING METHOD USING AGENT CONTROLLED RELEASE MATERIAL
To provide a method for simply manufacturing a belt-like string member containing a resin material, a novel member capable of suitably being used for an agent controlled release material, and a novel means for recycling a cylindrical tube such as waste vinyl chloride pipe.SOLUTION: There is provided a manufacturing method of a belt-like string member including; facing a blade to a circumferential direction of a cylindrical tube including a resin material, rotating the cylindrical tube while making the blade in contact with a surface of the cylindrical tube in an opposite direction to the direction of the blade, or rotating the blade along a circumference of the cylindrical tube while making the blade in contact with surface of the cylindrical tube in the direction of the blade, thereby removing the belt-like string member from the cylindrical tube including the resin material. There is provided a band-like string member including the resin member, which has a wide region and a narrow region and is curled.SELECTED DRAWING: Figure 1
