Waterproofing
Waterproofing is the process of making an object or structure waterproof or water-resistant so that it is not relatively damaged compared to water or prevents water from entering under certain conditions. Such items can be used in wet environments or in submerged depths. The specific definition of "waterproof/breathable" requires the fabric to withstand a pressure of one thousand millimeters of water (9.8 kPa) without leakage.
Waterproof fabrics
Waterproof
fabric is a fabric that is built-in, water-resistant, and wet.
Waterproof/breathable cloth prevents liquid water from passing through but
allows water vapor to pass through. The term waterproof refers to a regulatory
detail of an experimental method and is consistent with certain conditions. The
treatment can be one of the fabric during production or the whole product after
production, for example by waterproof spray. Examples include the Macintosh
jacket, the Sana suit, and the rubberized fabric used in inflatable boats.
The most common waterproofing treatment in the early 2000s was the application of C8 fluorocarbon-based textile finishes during manufacture. However, environmental and health concerns led to a transition to C6 fluorocarbon-based finishes and the development of alternative chemistries, such as ChemStik technology, a solvent-free process involving the on-surface polymerization of hydrocarbon chains.
Water-resistant
The definition of water-resistant is a matter that will not be destroyed by the liquid entering or in contact with the liquid but will instead remove the liquid. An example of a water-resistant watch is that you can wear it while swimming without ruining it.
Water-resistant
and waterproof often refers to the penetration of water in its liquid state and
possibly under pressure whereas damp-proof refers to moisture or damp resistance.
The entry of water vapor through any material or structure is reported as the
rate of wet vapor transmission.
Water-repellent
The water-resistant coating is basically just one step above the water-resistant
coating. If a device is identified as water-repellent, it actually possesses
features that you guessed it, make the water hydrophobic. Whether a
water-repellent device is indoors, outdoors, or both, it is much more likely to
be coated with some kind of thin-film nanotechnology and is much more likely to
stand in the water than your average device. Many companies claim
water-repellency, but the term is hotly debated because sustainable water
removal is rare and because of all the questions and unavoidable ingredients
associated with it.
Water repellency
Durable water-repellent (DWR) coatings are used in both water-resistant and waterproof jackets. The easiest way to explain what this coating does is to look at the surface of a new rain jacket during light rain. When you see water droplets roll up and roll off, you see water re-emerging.
