PROBLEM TO BE SOLVED: To provide a photosetting method of a photosetting lining material capable of performing rapid photosetting work by simple control and capable of obtaining a completed product of a tubular lining material of high quality, and a photosetting system.;SOLUTION: In the photosetting method of the photosetting material which includes a lining material introducing process for introducing the tubular lining material 10 in an uncured state into an existing pipe 100 to be regenerated so that the outside surface thereof advances along the inner wall of the existing pipe 100 to be regenerated and a light irradiation process for irradiating the introduced tubular lining material 10 with light from the inside thereof to cure the tubular lining material 10, a lining material preheating process for raising the temperature of the tubular lining material 10 to a temperature state becoming good in photosetting reaction is included before the light irradiation process. By this constitution, it is unnecessary to perform light irradiation of high output for preparing photosetting and the quality of the completed tubular lining material can be enhanced.;COPYRIGHT: (C)2008,JPO&INPIT
