What is the difference between breathable and non breathable?

Breathable and non-breathable are terms used to describe the ability of a material or fabric to allow air and moisture to pass through it. The main difference between the two lies in their permeability.

Breathable materials, as the name suggests, have the ability to let air and moisture move through them. These materials are designed to allow the circulation of air, which helps in regulating body temperature and preventing the buildup of heat and sweat. Breathable fabrics are commonly used in activewear, outdoor clothing, and medical textiles.

Non-breathable materials, on the other hand, do not allow air or moisture to pass through them. They create a barrier that traps heat, moisture, and sweat next to the body. Non-breathable fabrics are often used in protective clothing, such as raincoats or jackets designed to keep water out.

The choice between breathable and non-breathable materials depends on the intended use and the desired properties of the fabric. Here are some key differences between the two:

1. Comfort: Breathable materials offer greater comfort by allowing heat and moisture to escape from the body. This can help prevent overheating, sweating, and discomfort during physical activity. Non-breathable materials, on the other hand, can lead to a buildup of heat and moisture, which can cause discomfort and clamminess.

2. Moisture management: Breathable materials have the ability to wick away moisture from the skin, allowing it to evaporate more quickly. This helps in keeping the body dry and reducing the risk of skin irritation. Non-breathable materials do not have this moisture-wicking property and can lead to a feeling of dampness.

3. Durability: Non-breathable materials are often thicker and more tightly woven, making them more durable and resistant to tearing. Breathable materials may have a looser structure to allow air and moisture flow, which can potentially make them less durable.

4. Water resistance: Non-breathable materials are typically water-resistant or waterproof, as they do not allow water to penetrate through the fabric. This makes them suitable for use in wet weather conditions. Breathable materials, however, may not be water-resistant and may require additional treatment or coatings to make them waterproof.

5. Versatility: Non-breathable materials are commonly used in protective clothing where the primary concern is keeping out external elements such as water, chemicals, or particulates. Breathable materials are more versatile and are used in a wider range of applications, including sportswear, outdoor gear, and medical textiles.

In summary, breathable materials prioritize comfort, moisture management, and air circulation, making them ideal for active and outdoor activities. Non-breathable materials prioritize protecting against external elements such as water or chemicals. Both types of materials serve different purposes and it is important to consider the specific requirements of the intended use when choosing between breathable and non-breathable fabrics.
