Light-shielding container for light-sensitive material using light-shielding cloth and light-sensitive material package

A light-sensitive material package comprising:

• a light-shielding container for a light-sensitive material;
• and
• a light-sensitive material that has sensitivity to light at 850 nm and is housed in the container, the light-shielding container for a light-sensitive material comprising:
• a light-shielding cloth attached to an opening in the container through which the light-sensitive material is passed, the light-shielding cloth shielding the opening from light and comprising:
• a base fabric;
• and
• a pile section formed by incorporating pile threads into the base fabric, the pile section comprising:
• a black dope-dyed thread pile section formed by incorporating black dope-dyed threads containing carbon black;
• and
• a black-dyed thread pile section formed by incorporating black-dyed threads;
• wherein the proportion of the black dope-dyed thread pile section in the total pile section is 5 wt % to 60 wt %;
• wherein the single filament fineness of the black dope-dyed threads is thicker than that of the black-dyed threads;
• wherein the overall pile density of the black dope-dyed threads and the black-dyed threads is 30,000 filaments/cm2 to 55,000 filaments/cm2;
• and
• wherein the black dope-dyed thread pile section and the black-dyed thread pile section are arranged in stripes that are substantially orthogonal to the direction in which the light-sensitive material is passed.
