Abstract: Retroreflective-treated fabrics, and products and methods for forming the treatments are taught. As an example, a free-flowing mass of minute retroreflectorization particles that each comprise hemispherically reflectorized transparent microspheres supported in a softenable binder material are cascaded onto a fabric. The binder material is softened during application to provide adhesion of the particles to the fabric. A very sparse retroreflective treatment can be provided, which leaves the fabric with nearly its full original appearance as well as hand, feel, and breathability. Yet the treatment will greatly increase the safety of a pedestrian by making him visible at night.

REFERENCE TO RELATED APPLICATION
    This application is a continuation-in-part of pending application Ser. No. 540,286, filed Jan. 10, 1975, now abandoned.

Family: Show 23 known family members

First Claim:
Show all 40 claims
What is claimed is:     1. Fabric treated on at least one surface with a discontinuous sparse retroreflective treatment that has low visibility in daylight but provides a bright retroreflection at night, said treatment comprising discrete separated retroreflective areas that each include a thin layer of binder material adhered to the fabric and separated from the binder material of other retroreflective areas, and one or more glass microspheres that average no more than about 200 micrometers in diameter supported as a monolayer in said layer of binder material; at least about one-third of microspheres adhered to the fabric in said retroreflective areas having specular reflective means in optical connection between them and the fabric and having their outwardly facing surface optically exposed for receiving and returning light rays, whereby they retroreflect incident light that is normal to the fabric; there being no more than about 2000 microspheres in any square centimeter of said treatment; and the maximum surface dimension of said retroreflective areas being no greater than about 1 millimeter.
