How is waterproof clothing made
We recommend the following guidelines for MVTR:. MVTR is a tricky measurement: there are multiple methods for testing it and each method favours different fabrics. Manufacturers usually just quote the most flattering results for their garments, which can make comparisons difficult.
Humidity Breathability in waterproof jackets depends on 'solid state diffusion': water vapour is absorbed through the fabric and passed to the other side. The water vapour will always try to move to the least humid side of the fabric to maintain an equilibrium. In most conditions this means the water passes from the inside to the outside of the jacket.
Air permeability Air permeability is the measurement of how much air a fabric allows to pass through it. Not all waterproofs have an air permeability rating, but jackets with this rating will probably have a lower MVTR than jackets without. Features Pockets in your jacket can affect the breathability because they add another layer of fabric to your jacket.
Some jackets have crafty mesh pockets to reduce fabric and allow you to dump excess heat and sweat too. Dirt and abrasion: Dirt and abrasion could be stopping your DWR from working , reducing breathability.
Which brings us to A Durable Water Repellent DWR is a fabric coating that stops water from soaking into your jacket, causing it to bead up and roll off instead. When this happens your jacket loses its breathability, becomes heavier and feels colder because wet fabric conducts heat away from your skin.
Regular cleaning and reproofing maintain the DWR coating so your jacket continues to repel water. Your DWR makes water bead up into droplets and roll off the surface of your waterproof so that it maintains its breathability.
The only thing you really need to know about the DWR is what affect it has on the environment. Historically, the outdoor industry exclusively used C8 DWRs for their incredible durability.
As a result, the industry shifted to using C6 DWRs. These were less durable and required more maintenance than C8, but they didn't accumulate as much or produce toxic by-products. However, all PFCs, even the less harmful C6 chemicals, build up in the environment. Hopefully, you should now have a better idea of what all that complicated spec on your waterproof jacket means.

Other factors than can affect the breathability of a fabric are how clean the garment is. If your jacket is dirty, and contaminated with dirt, grime, oils, etc.
Then the pores that the vapour is trying to escape through will be blocked. Also, one of the most important aspects of breathability is how good the DWR Durable Water Repellent coating is on a garment.
Below is a list of waterproof and breathability ratings of various fabrics:. Breathability is heavily influenced by the environment, activity levels, cleanliness of the garment and its DWR. Ratings are only a guide and should not be the sole factor in choosing which garment to buy. In order to maintain breathability, the garment must be cleaned and reproofed regularly.
