Hey there! As a supplier of TR spandex fabric, I often get asked about the breathability rate of this amazing material. So, I thought I'd take some time to break it down for you.
First off, let's talk about what TR spandex fabric is. TR stands for polyester and rayon blend, and when you add spandex into the mix, you get a fabric that's stretchy, durable, and has a great drape. It's commonly used in all sorts of clothing items, from TR Pants Fabric to Kain TR Twill Fabric and TR Spandex Suiting Fabric.
Now, onto the big question: what's the breathability rate of TR spandex fabric? Well, it's a bit tricky to give a one - size - fits - all answer because it depends on a few factors.
Factors Affecting Breathability
1. Fiber Composition
The ratio of polyester, rayon, and spandex in the fabric plays a huge role. Polyester is known for being hydrophobic, which means it doesn't absorb moisture well. However, it can help the fabric dry quickly. Rayon, on the other hand, is more absorbent and has better breathability compared to polyester. Spandex is there mainly for stretch, and in small amounts, it doesn't have a huge impact on breathability.
A fabric with a higher percentage of rayon will generally be more breathable. For example, if a TR spandex fabric has 60% rayon, 35% polyester, and 5% spandex, it'll likely have better breathability than a fabric with 80% polyester, 15% rayon, and 5% spandex.
2. Fabric Construction
The way the fabric is woven or knitted also affects breathability. A looser weave or knit allows more air to pass through the fabric, increasing its breathability. For instance, a plain weave fabric might be less breathable than a twill weave with a looser structure. In a twill weave, the diagonal pattern creates more space between the yarns, enabling better air circulation.
3. Finish Treatment
Sometimes, fabrics are treated with various finishes for different purposes like water - repellency or anti - wrinkling. These finishes can have an impact on breathability. A heavy water - repellent finish might create a barrier that reduces the amount of air and moisture that can pass through the fabric.
Measuring Breathability
There are a few ways to measure the breathability of a fabric. One common method is the moisture vapor transmission rate (MVTR). MVTR measures how much moisture vapor can pass through a fabric in a given period. A higher MVTR means the fabric is more breathable.
Another way is the air permeability test. This test measures the volume of air that can pass through a unit area of the fabric in a specific time under a certain pressure difference. Fabrics with high air permeability allow more air to flow through, which is a sign of good breathability.
Typical Breathability Rates of TR Spandex Fabric
On average, a well - made TR spandex fabric with a good balance of polyester and rayon can have an MVTR ranging from 1000 to 3000 grams per square meter per 24 hours. Fabrics with a higher rayon content and a looser construction will be on the higher end of this range.
In terms of air permeability, the values can vary widely. A fabric with a high air permeability might have values around 50 - 100 cubic feet per minute per square foot (CFM/ft²), while a less breathable fabric could have values as low as 10 - 20 CFM/ft².
Benefits of Breathable TR Spandex Fabric
Comfort
Breathable fabrics are much more comfortable to wear, especially in warm weather or during physical activities. They allow sweat and moisture to evaporate quickly, keeping the body dry and cool. This reduces the feeling of stickiness and discomfort that you might experience with non - breathable fabrics.
Health
Wearing breathable fabrics can also be beneficial for your skin. When sweat can't escape from the fabric, it can create a breeding ground for bacteria, which can lead to skin problems like rashes and infections. Breathable TR spandex fabric helps prevent these issues by allowing the skin to breathe.
