This experiment was conducted to discover how the comparative flammabilities of protein, cellulose and synthetic fibers are affected by duration of contact with direct flame, so that a recommendation could be made regarding the safest fiber content for apparel worn by elderly people living independently.

          To discern this, six cellulose, six protein, and six synthetic fiber fabrics of comparable apparel application were tested.  For each of these eighteen fabrics, six samples were tested in two different tests consisting of three trials each.  The three trials of test one were conducted with match flame contact of one second.  The three trials of test two were conducted with match flame contact of two seconds.  Each of the 108 fabric samples was photocopied against a measuring grid prior to testing, and the precise percentage of area affected by the burn was calculated after flame contact.  All trials were filmed.  The precise duration of combustion was measured with a stopwatch and recorded as burn time.

          This experiment showed that duration of contact with direct flame had the greatest affect on the flammability of moderately flammable protein fibers, and certain types of synthetic fibers.    Cellulose fibers were most consistently flammable.  Certain protein and synthetic fabrics were flame resistant, while others were highly combustible.  Fabric weave and density affected rate of flame spread.

          It was concluded that modacrylic fibers were by far the most consistently flame resistant, and would make the safest garments for elderly people.
