Hey there! As a supplier of absorbent pad fabric, I've been getting a lot of questions lately about how the porosity of the fabric affects its absorbency. So, I thought I'd take a few minutes to break it down for you.
First off, let's talk about what porosity actually means. In simple terms, porosity refers to the amount of empty space or pores within a material. In the case of absorbent pad fabric, these pores act like little reservoirs that can hold liquid. The more pores a fabric has, and the larger those pores are, the more liquid it can absorb.
Now, you might be wondering how porosity is measured. Well, there are a few different ways to do it, but one of the most common methods is to use a technique called mercury intrusion porosimetry. This involves forcing mercury into the pores of the fabric under high pressure and measuring how much mercury is absorbed. The results can then be used to calculate the porosity of the fabric.
So, how does porosity affect absorbency? Well, it's pretty straightforward. The more porous a fabric is, the more liquid it can hold. This is because the pores provide more surface area for the liquid to come into contact with, which allows it to be absorbed more quickly and efficiently. Additionally, larger pores can hold more liquid than smaller pores, so fabrics with larger pores tend to have higher absorbency.
However, it's important to note that porosity isn't the only factor that affects absorbency. Other factors, such as the type of fiber used in the fabric, the density of the fabric, and the surface treatment of the fabric, can also play a role. For example, fabrics made from natural fibers like cotton tend to be more absorbent than fabrics made from synthetic fibers like polyester. This is because natural fibers have a more porous structure and can absorb more liquid.
Another factor to consider is the density of the fabric. Fabrics that are more tightly woven or knitted tend to have lower porosity and lower absorbency than fabrics that are more loosely woven or knitted. This is because the tight weave or knit reduces the amount of empty space within the fabric, which limits the amount of liquid that can be absorbed.


Finally, the surface treatment of the fabric can also affect its absorbency. Fabrics that have been treated with a hydrophobic coating, for example, will be less absorbent than fabrics that have not been treated. This is because the hydrophobic coating repels water and prevents it from being absorbed into the fabric.
So, how can you choose the right absorbent pad fabric for your needs? Well, it depends on a few factors, such as the type of liquid you need to absorb, the amount of liquid you need to absorb, and the environment in which the fabric will be used. For example, if you need to absorb a large amount of liquid quickly, you'll want to choose a fabric with high porosity and high absorbency. On the other hand, if you need to absorb a small amount of liquid over a longer period of time, you might be able to choose a fabric with lower porosity and lower absorbency.
