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.
SEARING
The cut ends of nylon tape, webbing, and cord lengths may be prepared by heat-searing; this 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.
WAXING
The fraying or unraveling of cotton or nylon tape, webbing, and cord length ends may be prevented by dipping
½-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.
