Hey there! As a supplier of Laminated Non Woven Fabric, I often get asked this question: "Is laminated non woven fabric breathable?" Well, let's dive right into it and find out.
First off, let's understand what laminated non woven fabric is. Laminated non woven fabric is made by bonding a non woven layer with one or more other materials, like films or foils. This lamination process gives the fabric some extra properties, such as water resistance, durability, and sometimes, a better look. You can learn more about Laminated Non Woven Fabric on our website.
Now, when it comes to breathability, it's a bit of a mixed bag. Breathability in fabric means how well air and moisture can pass through it. In the case of laminated non woven fabric, whether it's breathable or not depends on a few factors.
One of the main factors is the type of materials used in the lamination. If a non breathable film is laminated onto the non woven layer, the overall breathability of the fabric is going to be significantly reduced. For example, if a thick plastic film is laminated, it can act as a barrier, preventing air and moisture from passing through. This type of laminated fabric is great for applications where you need high water resistance, like in outdoor covers or some types of packaging. But if breathability is your main concern, it might not be the best choice.
On the other hand, there are ways to make laminated non woven fabric more breathable. Some manufacturers use special breathable films or coatings. These materials are designed to allow air and moisture vapor to pass through while still providing some level of protection. For instance, in the production of medical gowns or some sports clothing, breathable laminated non woven fabrics are used. They need to keep the wearer dry and comfortable by allowing sweat vapor to escape, while also providing a barrier against liquids and contaminants.
Another factor that affects breathability is the structure of the non woven layer itself. Non woven fabrics can have different densities and pore sizes. A non woven layer with larger pores will generally allow more air to pass through. When this non woven layer is laminated, the breathability can still be somewhat maintained, especially if the lamination process doesn't completely block those pores.
Let's talk about some real - world applications and how breathability matters. In the agriculture industry, laminated non woven fabric is used for crop covers. If the fabric is breathable, it allows air circulation around the plants. This helps prevent the build - up of humidity, which can lead to mold and disease. At the same time, it can protect the crops from pests and harsh weather conditions.
In the automotive industry, laminated non woven fabric is used for interior components. Breathable fabrics can enhance the comfort of the passengers by allowing air to flow, reducing the feeling of stuffiness. This is particularly important in hot climates.
Now, let's get into the testing of breathability. There are several standard tests used to measure the breathability of fabrics. One common test is the moisture vapor transmission rate (MVTR) test. This test measures how much moisture vapor can pass through a fabric in a given time. A higher MVTR value indicates better breathability. Another test is the air permeability test, which measures the volume of air that can pass through a unit area of the fabric under a specified pressure difference.
As a supplier, we understand the importance of breathability for different applications. That's why we offer a range of laminated non woven fabrics with varying levels of breathability. Whether you need a highly breathable fabric for a comfort - oriented application or a less breathable but more water - resistant one for an outdoor use, we've got you covered.
If you're in the market for laminated non woven fabric and have specific breathability requirements, we'd love to have a chat with you. We can help you choose the right product based on your needs. You can contact us to discuss your project, and we'll work with you to find the best solution.
