摘要:
A light-shielding container for a light-sensitive material has a light-shielding cloth attached to an opening in the container through which the light-sensitive material is passed. The light-shielding cloth shields the opening from light and is formed from a base fabric and a pile section. The pile section includes black dope-dyed threads formed by incorporating black dope-dyed threads containing carbon black into the base fabric and black-dyed threads formed by incorporating black-dyed threads. The proportion of the black dope-dyed threads in the total pile is 5 wt % to 60 wt %. The single filament fineness of the black dope-dyed threads is thicker than that of the black-dyed threads. The overall pile density of the black dope-dyed threads and the black-dyed threads is 30,000 to 55,000 filaments/cm2. The black dope-dyed threads and the black-dyed threads are arranged in stripes substantially orthogonal to the direction in which the light-sensitive material is passed.
