Do you know the difference between water-repellent, waterproof, moisture-permeable, breathable and windproof?

Water-repellentThe water-repellent property of the fabric means that the fabric has been treated with a water-repellent agent and its surface can be The water droplets are formed into a bead shape and will not penetrate or spread to wet the clothes, achieving a water-splashing function like a lotus leaf (lotus effect). Water-repellent finishing uses this principle to attach a layer of ultra-fine “needle beds” to the surface of the fabric with various chemical materials, so that the tension on the surface of the fabric is less than the cohesion of water, so when water drops, water droplets will form and roll away. Not spread out and soaked. If the needle bed structure of this layer is flattened or covered with oil and infiltrated, the water-repellent ability of the fabric will be greatly reduced, and it may even begin to absorb water.
Water repellentFunctional treatment to prevent water infiltration. Current water-blocking treatments often use water-blocking films to prevent water molecules from penetrating in. However, the film itself is too fragile, so it must rely on the surface, film, and interior to cooperate with each other. In order to achieve the water-repellent function. The water-blocking ability is expressed by the water pressure resistance value, that is, a fixed area of ​​​​water-repellent cloth is used to block the rising water pressure. When the third drop of water seeps out from the surface, it is the water pressure resistance value of the fabric. Usually it exceeds 1000mm. Achieve basic water blocking ability.
BreathableSpecifically refers to the indirect breathable and water-repellent film provided Function, not to mention breathability, because they have two different ventilation mechanisms, although they can still allow sweat to escape through the fabric to the outside world. Breathability requires sweat to be absorbed by the hydrophilic non-porous membrane and become sweat molecules inside, and then move to the outside of the film in a slightly brown and casual manner, affected by the humidity and pressure difference between the inside and outside of the work clothes, and then turn into gas and be discharged through the surface fabric. So it is called indirect breathability.
Breathable specifically refers to water-repellent porous membranes The function provided by the water-blocking film, breathability, is to allow gas to directly pass through the gaps of the “water-repellent porous film”. Because of its faster speed, it is called direct breathability.
Wind-blockingAs long as the fabric is used, it has a certain degree of wind-blocking Function, the more tightly the fabric is woven, the stronger its ability to block wind. Those with poor air permeability generally have stronger wind blocking capabilities. High-quality fabrics perfectly combine breathability and wind resistance.
