How to read the waterproof and moisture permeability coefficients?
In our previous blog article, we introduced to you the difference between "water repellent" and "waterproof" .
This article will continue to explain to you how to look at the "waterproof" and "moisture permeability" coefficients?
Waterproof and moisture-permeable functional fabric uses special processing to allow the fabric to block the penetration of rain and strong wind.
It also dissipates the vapor released during body movements to the outside through the fabric.
When the climate is hot, it can achieve a cooling effect; when the climate is cold, there will be no moisture condensation in the clothes to cause coldness, keeping the body dry and comfortable.
Waterproof coefficient Waterproof
"Waterproof function" refers to applying a waterproof coating (Coating) or a layer of waterproof film (Lamination) on the back of the fabric.
Used to prevent rain and strong wind from penetrating. Therefore, even under heavy rain, if you can wear a functional jacket with a high waterproof coefficient, the clothes inside will hardly be soaked by the rain!
"Waterproof coefficient" (mmH2O) is how many centimeters (mm) of water column impact per square centimeter (mm) area can withstand without water seepage. The larger the value, the stronger the waterproofing capability.
INC/REPURPOSE waterproof functional jackets mainly use lamination processing.
Press a waterproof or waterproof and moisture-permeable film onto the fabric. The fabric will feel softer and more durable than the coating process;
The waterproof coefficient is guaranteed to be at least 5,000mm H2O, which is used to cope with sudden heavy rains when commuting to work or traveling in the countryside.
There is absolutely no problem! But if you need to go hiking or skiing outdoors all day, it is recommended to choose a professional jacket with a water pressure resistance of 8,000~10,000mm H2O which is more suitable~
Moisture Vapor Permeability
"Moisture permeability" refers to whether the sweat and moisture discharged from the human skin can be quickly discharged through the fabric?
The greater the amount of exercise, the more you sweat, and you will need a jacket with better breathability to make it more comfortable to wear.
INC/REPURPOSE waterproof and breathable functional jacket series not only guarantees a waterproof coefficient of at least 5,000mm H2O,
The moisture permeability coefficient can also reach between 7,000 ~ 20,000 g/m2.24hrs (depending on the number of layers of fabric).
When you are engaged in outdoor leisure activities or commuting to and from get off work, you can not only avoid getting wet from heavy rain, but also keep you dry and comfortable at all times.
Before you plan to buy a waterproof and breathable functional jacket, you can first consider the wearing occasion and the intensity of the activity.
Generally speaking, the higher the waterproof coefficient, the slightly lower moisture permeability coefficient;
On the other hand, if you want a higher moisture permeability coefficient, you may not need to choose a high-performance waterproof coefficient of 8,000~10,000 mm/mmH2O or above.
In Taiwan, which has a humid and rainy climate, hurry up and choose a practical and easy-to-match waterproof and breathable functional jacket for yourself and your family!
