Absorbency
Cloth Diaper test results
What is Absorbency Testing?
Absorbency testing is a some-what controlled method of understanding how a cloth diaper absorbs liquid. It’s an unofficial measure of how a product performs using kitchen science and helps us create a scale of reference to better understand how products work together.
My Approach
I weight the product, then pour warm water over the product until the cloth diaper is soaked. I let any drips drip, and weigh the saturated product.
I repeat three times and take an average in fluid ounces.
Just an Estimate
This is just an estimate of the products maximum absorbency function.
Real life results will vary and maximum absorption IRL would cause leaky diapers.
Performance
The amount of liquid is not the only indicator for successful cloth diapering – the way a material absorbs and holds onto liquid is another key performance indicator. This is not indicated here but I did chat about a bit on my youtube channel.
It’s more than the type of textile
Absorbency is about the products weave, blend, and quality
It’s easy for cloth diaper bloggers and brands to say “hemp is the most absorbent” but that’s a broad statement that doesn’t adequately support you in finding the right cloth diaper. Every textile performs differently, and the conversation should be about finding the right product designed by brands to meet your needs as a cloth diaper family. This might mean that a cotton cloth diaper is the best choice for an overnight diaper for your family.

oooooh I love this! This is the information needed when looking at these products, it tell you what to expect and I can see why my daughter is soaking her AMP bamboo insert to quickly now. I can also see some other products that I can try!
Sad to see the Disana insert so low. The more research I do I the more obsessed with their system I am becoming. Do you think pairing with a hemp booster would make it a good day option?
These results would be better displayed if they were normalized. Of course the prefold toddler is going to absorb more simply based on the fact that it is larger. If you wanted to have results which compared performance, publish a the result in terms of oz/ft^3, i.e., divide the absorption by the volume of the diaper.
