Waxed cotton combines its breathability and softness with the added water-resistant properties of wax coating. This material is often chosen for its traditional and natural feel.

Properties:

  • Aesthetic Appeal: Offers a vintage, rugged appearance.
  • Breathable: Allows air circulation while resisting moisture.
  • Renewable Water Resistance: The wax coating can be reapplied to maintain its effectiveness.

Applications in Blankets: Waxed cotton is commonly found in heritage-style camping blankets or outdoor products aimed at eco-conscious consumers who prefer natural fibers over synthetics.

How Are Waterproof Blankets Designed?

The construction process of a waterproof blanket is as vital as the materials used. The design ensures that each blanket meets performance standards and remains reliable in real-world applications.

1. Layering

Most waterproof blankets are made of three distinct layers, each playing a critical role:

  • Inner Layer: Designed for comfort, this layer often uses fleece or cotton to ensure a pleasant feel against the skin.
  • Middle Layer: The waterproof core, made from materials like TPU or PUL, blocks moisture effectively.
  • Outer Layer: Built for durability, nylon or polyester protects the blanket from abrasions, dirt, and wear.

2. Seam Sealing

To ensure no water seeps through the stitching, manufacturers use sealed seams. This involves applying waterproof adhesive tape or heat-sealing techniques, creating a fully watertight product.

3. Coatings and Treatments

Fabrics often receive Durable Water-repellent (DWR) treatments to enhance their performance. These treatments cause water to bead up and roll off the surface, preventing absorption and maintaining the blanket’s integrity.

Benefits of Advanced Waterproofing Technology

1. Enhanced Longevity

Advanced waterproofing materials like TPU and PUL extend the durability of blankets. Unlike older coatings that degrade over time, these modern solutions maintain their water-repellent properties even after extensive use and washing. This longevity makes them cost-effective in the long run.

2. Improved Usability

Waterproof blankets now include breathable layers that make them comfortable to use in a variety of climates. Features like seam-sealed stitching and advanced treatments ensure that water doesn’t seep through, improving their overall functionality.
