Water-Resistant Breathable Fabrics

The first part of this paper covers the questions: How can we obtain WBFs (waterproof breathable fabrics)? and What is available? A description of the technique to obtain such fabrics with a statement of general advantages and disadvantages is covered. There are three techniques:

1. High-density fabrics

2. Lamination: extruded, melt-blown, or cast film being microporous and/or hydrophilic

3. Coating: microporous and/or hydrophilic

Part two covers:

• the measurement of waterproofness and breathability

• breathability test methods and influencing parameters

• waterproofness tests

Part three considers the question: What other properties are wanted and what are the markets and their requirements?

Part four considers: Where will be the use of such WBFs in the textile market?
