Cotton cords should be waxed for what purpose?

• A. Prevent mildew, moisture
• B. Increase strength
• C. Improve conductivity
• D. Reduce weight

Answer: (A)

Waxing cotton cords is done to repels moisture and prevent mildew. Cotton fibers readily absorb water, which can weaken insulation, promote swelling, and encourage mold in damp environments. A wax coating creates a hydrophobic barrier that limits water absorption, helping maintain insulation integrity and cord flexibility in humid conditions. This isn’t primarily about increasing strength, improving conductivity, or reducing weight—the wax’s main job is moisture control and mildew prevention.
