CAUTION
Cotton tape, webbing, or cord will not be seared.
NOTE
Fabric materials such as cord, tape, and webbing that are cut for use In the
maintenance of parachutes will normally be heat-seared or dipped. In a melted
wax mixture, as. applicable, to prevent the material from fraying or unraveling.
However, in some instances the preparation of the material may not be necessary
and will be specified accordingly.
a.
Searing. The cut ends of nylon tape, webbing, and cord lengths may be prepared by heat-searing
which is performed by pressing the raw end of the material against a hot metal surface (knife) until the nylon
has melted sufficiently. Avoid forming a sharp edge or lumped effect on the melted end.
b.
Waxing. The fraying or unraveling of cotton or nylon tape, webbing, and cord length ends may be
prevented by dipping 1/2 inch of the raw end of the material into a thoroughly melted mixture of half beeswax
and half paraffin In an electric melting pot. The wax temperature should be substantial enough to ensure the
wax completely penetrates the material rather than just coating the exterior fabric.
