  • Method to produce light-lock fabric
    Patent number: 5539964
    Abstract: A container for a strip (12) of light-sensitive material includes an elongated opening for withdrawing the material from the container. Strips (22) of light-locking material are provided on both sides of the opening, the strips being made from a napped and sheared woven fabric (12, 14). The fabric is dyed, dried, napped, sheared and heat set prior to preparation of the strips. A method of producing such a light-locking material is taught which includes steps of passing the woven fabric multiple times through napping and shearing operations to increase the pile density.
