How to Heat Seal Fabric After Cutting With Scissors

Synthetic fabrics that have a high amount of plastic in their weave benefit from being sealed with heat after they are cut with scissors. Heat sealing the fabric prevents fraying and creates a sturdy edge that will not tear under normal pressure. Fabrics like nylon and dacron, which are often used in outdoor gear, both benefit from having their edges heat sealed after they have been cut.

Instructions

1. • 1

     Place a candle in a sturdy candle holder. The candle holder should keep the candle erect and stable.

   • 2

     Light the candle with a lighter.

   • 3

     Hold the cut edge of the synthetic fabric taut between your fingers.

   • 4

     Brush the edge of the fabric next to the candle flame, allowing the flame to lick at the edge of the fabric. The heat melts the plastic and seals the edge.

   • 5

     Singe between 3 and 5 inches of the fabric at a time, stopping often to ensure that the fabric does not catch fire.
