Abstract
The present invention provides an article, comprising: a fabric sheet which has been microcreped; and a curable resin coated onto the fabric sheet. The present invention involves microcreping or compacting a fabric sheet to impart stretchability and conformability to the fabric while minimizing undesirable recovery forces. Suitable fabrics for microcreping are fabrics which comprise fibers which are capable of first being mechanically compacted or 'crimped' and then being set or annealed in the crimped, i.e., distorted, state. The article may be in the form of an orthopedic bandage and may optionally contain a plurality of microfiber fillers dispersed into the resin. The incorporation of microfiber fillers into the casting materials of the present invention adds substantially to the strength of the cured casting material, particularly when the fabric used therein is a non-fiberglass fabric, while not detracting from the handling properties of the uncured casting tape.
