Can you think of any more? Examples of materials are plastic, fabric, metal, wood etc. Different materials have different properties, which make them useful for different functions. For example, glass is used in windows because it is transparent, we can see through it.
Water cannot pentrate waterproof materials. We would expect the foil and plastic bag to be waterproof, as this is what makes them useful for wrapping food, keeping it dry and protecting from smells.
Raincoats often have a plastic coating because plastic is waterproof. We would not expect the tea towel to be waterproof as tea towels are absorbent which makes them great for drying dishes.
Rubber and wax are examples of natural waterproof coatings that are used to make materials waterproof. Leaves often have a waxy coating to protect the leaf and help it retain water. The higher the number, the more waterproof the fabric. Grams — The second number is a measure of how breathable a fabric is, normally listed in terms of how many grams g of water vapor can pass through a square meter m2 of the fabric from the inside to the outside during a 24 hour period.
In the case of a 15k 15, g fabric, this would be 15, grams. The larger the number, the more breathable the fabric. Waterproof ratings are determined by the manufacturer brand or fabric producer in which waterproof testing is usually handled in-house or through independent labs.
What most consumers are not aware of, however, is that there are a number of waterproof testing procedures in use today. In simple terms — two pieces of fabric from the same exact roll could produce different results depending on the waterproofing test conducted. Today waterproof ratings are becoming more standardized, however do keep in mind different companies and labs may have different testing procedures that produce different results.
Five main breathability test methods exist. As a general rule of thumb, the higher the grams of water vapor that pass through, the greater the breathability. All breathable outerwear designed for active winter sports and rain protection has various degrees of water resistance, but will eventually leak given enough water, time and pressure.
Most normal jackets as well as big, tall and plus size winter jackets today feature waterproof, breathable fabric. Seam taping, sometimes referred to as seam sealing, is a heat applied thin waterproof tape that covers tiny holes made by the needle in the sewing process so the seams do not leak.
GORE also offers soft shell fabric and a super light 2. Gore Corporation. These are good examples of waterproof, artificial materials that you may find in many household items. From placemats to cosmetic bags, this type of fabric is very waterproof. Not only does it prevent water from seeping through, but it is also equally as tough as it is flexible, giving you the best of both worlds.
Thermoplastic polyurethane is very soft, supple and environmentally friendlier than other options such as PUL or Polyurethane Laminate. This waterproof material is good for reusable nappies due to its absorbent and comfortable nature.
Fleece is classed as a water-resistant fabric, as long as it is thick enough. Fleece is another type of fabric that comes in useful for the outer layer of cloth nappies. Carefully applying a water repellent coating can make fleece more water-resistant than it is naturally. Polyurethane Laminate is the fabric of all fabrics that are waterproof in its own right.
PUL is a polyester fabric that has a plastic backing comprising a thin waterproof layer. Polyurethane Laminate is a completely waterproof fabric, as well as being breathable and flexible. The best thing about polyester PUL is that it is thin, smooth, and it can be washed many times without causing any damage. Although it may not be fully waterproof, you can add a coat of lanolin and improve its protection significantly.
Boiled wool is extremely water-resistant as the boiling process makes the fabric thicker and denser. Oilcloth is essentially a linen cloth with a coating of boiled linseed oil to make it completely waterproof.
Modern-day, oilcloth can be created using cotton material plus a clear vinyl layer over the top. Oilcloth is low maintenance, wipe clean material that used for tablecloths, bags and kitchen accessories.
Here are the top branded waterproof fabrics that you can buy right now. The best in the industry and the most popular when it comes to waterproof fabric is most definitely Gore-Tex. Gore-Tex fabrics utilise an ePTFE membrane with an extremely thin polyurethane coating to create a waterproof, breathable fabric.
These fabrics are available in standard 2L and 3L constructions, along with a Gore-Tex precise lining construction. Gore-Tex creates its products with the future in mind; they promise that your product will remain protective for its entire lifetime.
The wide range of options with Pertex Shield is outstanding; they offer fabrics suitable for all sorts of conditions, from intense outdoor sports to long hikes. Pertex Shield also partners with brands such as The North Face. The membrane of the Polartec Neoshell uses a porous polyurethane.
