  • Patent number: 5407729
    Abstract: Disclosed is a method for applying light diffracting materials to a fabric in a selective pattern and which allows the fabric to withstand repeated laundering without significant deterioration of the light diffracting image. A base of adhesive resin with a layer of flexible material thereabove is adhered to the fabric in the desired selective pattern. A layer of light diffracting material is then bonded to the flexible material. The adhesive resin infiltrates the fabric and, when cured, the resin secures the fibers of the fabric in a controlled shape to prevent the fibers thereat from shifting relative to one another, thus substantially eliminating stretching and shearing forces in the layer of light diffracting material adhered thereto, which forces are commonly encountered during laundering.
