What is the Breathability Rating of a Typical PU Jacket?
As a supplier of PU jackets, I often get asked about the breathability rating of these jackets. Breathability is a crucial factor when it comes to outerwear, as it directly impacts comfort, especially during physical activities or in varying weather conditions. In this blog post, I’ll delve into what breathability rating means for a typical PU jacket, how it’s measured, and what factors can influence it. PU Jacket
To begin with, let’s understand what breathability in a jacket actually means. Breathability refers to the ability of the fabric to allow moisture vapor (such as sweat) to pass through it and escape from the body. When we exercise or are in a warm environment, our bodies produce sweat. If the jacket we’re wearing doesn’t allow this moisture vapor to escape, it can accumulate between our body and the jacket, making us feel damp, cold, and extremely uncomfortable. This is where a high – breathability rating comes in handy.
A PU (Polyurethane) jacket typically uses a PU coating on the fabric. PU is a synthetic material known for its water – resistance, durability, and flexibility. However, the typical breathability of a PU jacket can vary widely, depending on several factors.
One of the key ways to measure the breathability of a jacket is through the MVTR (Moisture Vapor Transmission Rate). The MVTR is expressed in grams per square meter per 24 hours (g/m²/24h). A higher MVTR indicates better breathability. For a typical PU jacket, the MVTR can range anywhere from 2,000 g/m²/24h to 20,000 g/m²/24h.
Jackets with an MVTR of around 2,000 – 5,000 g/m²/24h are considered to have low to moderate breathability. These jackets are usually more suitable for light – activity situations or colder climates where you’re not likely to sweat excessively. They still provide decent water – resistance and protection from the elements, but sweating can become an issue if you’re engaging in high – intensity activities.
On the other hand, PU jackets with an MVTR of 10,000 – 20,000 g/m²/24h are known for their high breathability. These jackets are ideal for those who lead an active lifestyle, such as hikers, cyclists, or athletes. They allow a large amount of moisture vapor to escape, keeping you dry and comfortable even during intense physical exertion.
Now, let’s look at the factors that can influence the breathability rating of a PU jacket:
Fabric Composition
The base fabric on which the PU coating is applied plays a significant role in breathability. Natural fibers like cotton are generally more breathable than synthetic fibers, but they may not be as durable or water – resistant. Some manufacturers use a blend of natural and synthetic fibers to balance breathability and performance. For example, a fabric blend of cotton and polyester can provide good breathability while maintaining the necessary strength and water – resistance for a PU jacket.
PU Coating Thickness
The thickness of the PU coating is another critical factor. A thicker coating will generally provide better water – resistance but may reduce breathability. This is because a thicker layer of PU acts as a more significant barrier to the passage of moisture vapor. Conversely, a thinner PU coating may allow more moisture vapor to pass through but may compromise on water – resistance to some extent. Manufacturers need to find the right balance between these two factors based on the intended use of the jacket.
Porousness of the Coating
Some advanced PU coatings are designed to be porous at the microscopic level. These pores are small enough to prevent water droplets from entering but large enough to allow moisture vapor to escape. This type of technology can significantly improve the breathability of a PU jacket. However, the manufacturing process for these porous coatings can be more complex and expensive, which may be reflected in the price of the jacket.
Lamination and Construction
The way the jacket is constructed can also affect its breathability. For example, a laminated construction where the PU layer is bonded to the base fabric in a certain way can either enhance or impede breathability. Additionally, details such as the type of seams used and the presence of ventilation panels can make a difference. Sealed seams can improve water – resistance but may reduce breathability, while strategically placed ventilation panels can increase air circulation and allow moisture vapor to escape more easily.
