Are the moisture permeability and breathability of fabrics the same?
Functional fabrics provide us with the necessary safety protection to protect us from damage. After we solve the safety problems, what we consider is the comfort of wearing functional fabrics. Comfort will first be judged from the breathability performance. Breathability is a characteristic we often talk about, so what is the concept of breathability?
Water repellent: Functional treatment to prevent water infiltration. Current water-repellent treatments often use water-blocking films to prevent water molecules from penetrating deeply. However, the film itself is too fragile, so it must rely on surface fabrics and films. , the inner and outer parts must cooperate with each other 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-blocking cloth is used to block the rising water pressure. When the third drop of water seeps out from the surface, it is the cloth. The water pressure resistance value usually exceeds 1000mm to achieve basic water resistance.
Breathable:Specifically refers to the functions provided by the indirect breathable and water-repellent film, not breathability, because they are two different breathable mechanisms, although they can eventually allow sweat to escape It is emitted to the outside world through the fabric. Breathability requires sweat to be absorbed by the hydrophilic non-porous membrane and become sweat molecules inside. In a micro-Brown casual manner, affected by the humidity and pressure difference between the inside and outside of the work clothes, it moves to the outside of the film, and then transforms into sweat molecules. The gas is discharged through the surface fabric, so it is called indirect ventilation.
A detailed explanation of breathability and breathability, we I also understand these two characteristics better, so since it is breathable, does it also have a good wind-blocking function? Let’s continue to explain to you what the wind-blocking performance of fabric is.
Wind blocking: As a kind of fabric, fabrics are bound to be ventilated, but the intensity of ventilation is different. The more tightly the fabric is woven, the stronger its wind-blocking ability. Those with poor air permeability generally have stronger wind-blocking ability. High-quality fabrics perfectly combine breathability and wind resistance. In response to this, technology has achieved not only superior wind resistance and high fabric quality, but also breathability, which makes our protective clothing more comfortable to wear. Here comes a higher experience.
