Orthopedic Fiberglass Casting Tapes Gained Widespread Commercial Acceptance (2)
U.S. Patent No. 5,088,484 discloses a cast bandage which comprises an open-mesh fibrous tape having a hardenable resin coated on the orthopedic fiberglass casting tape which is capable of curing to form a hardened plastic. The tape has applied thereto at least one coloring agent which is visibly disposed on at least a portion of the fibrous tape, the coloring agent is stablely retained by the fibrous tape in the presence of hardenable liquid resin.
In attempting to print on cast bandages made from fiberglass substrate, there have been several problems identified. One of them is a poor physical bond between the printing ink and the fiberglass filaments. The nature of the fiberglass surface is not capable of absorbing most dyes or pigments preventing the good adhesion necessary to maintain the pigment in the presence of the curable resin.
