What Is Waterproof?

When we talk about waterproof, we are referring to the ability of a garment or fabric to stop water from passing through. There are a number of tests and standards that products can be subjected to to ensure that they meet this requirement, ensuring that consumers don't end up with items that are not fit for purpose. In terms of clothing, the best waterproof materials are usually made from synthetic fabrics such as polyurethane, silicone elastomer and fluoropolymers. Waterproof materials are also often laminated or coated with a waterproof product to make them fully waterproof.

A waterproof garment can be worn in a range of situations. It may be used by marine biologists to record data from fish or by outdoor enthusiasts for hiking, camping and other activities. In addition, waterproof materials are often used in the construction of buildings and can be applied to walls, roofs, flooring and other surfaces to protect them from damage caused by water seepage.

There are a number of factors that go into making an item of clothing waterproof, with one of the most important being how tightly it is woven. Waterproof materials are extremely durable and thick, but they are also breathable, meaning that sweat is able to evaporate through the material rather than being soaked into the skin. This is vitally important as if we allow sweat to soak into our clothing, we will become uncomfortable and cold very quickly.

Waterproof materials also have a membrane that prevents moisture from penetrating the outer layer. These membranes can be derived from a variety of sources, including Teflon (ePTFE), polyurethane and polyvinyl chloride. These membranes are incredibly hard-wearing and can be extremely lightweight, which is ideal for outdoor clothing that needs to be comfortable as well as protective.

The final factor that goes into making a fabric or garment waterproof is how the seams are sealed. Ideally, they should be taped so that water is unable to get through the seams. This is especially important when it comes to hiking, walking or biking clothing as a single small leak can lead to a cold, wet and uncomfortable experience.

In addition to the benefits offered by waterproof materials, they are also a great way to reduce waste and improve sustainability. For example, many restaurants use paper menus for their customers, but if these aren't properly waterproofed, they can tear easily when exposed to liquids like water and food. By switching to plastic or laminated menus, restaurants can help to cut down on waste and save money at the same time. Similarly, by using waterproof paper, outdoor enthusiasts can enjoy their hikes without having to worry about their maps getting ruined by rain, sleet or snow. Waterproof paper is also a great option for national parks and other destinations that offer trail maps to their visitors as it allows them to take notes on the map without worrying about it smudging or tearing. It is also easier to sanitize than regular paper and can be recycled at the end of its life.
