Inserts are for the main absorbancy source and can be made of cotton, bamboo, hemp or microfiber (which can't touch baby's skin).
Doublers can be made of the same materials, but are just used for an extra dose of absorbancy, not alone.
Liners are used to pull absorbancy down away from the baby's skin, but do not absorb anything themselves. So you'd put them in with an insert underneath. These are usually made of fleece or wool or rice paper (disposable).
What do I have wrong? What am I forgetting?
Re: Do I have this right?
Sounds about right, although I can't say I've ever heard of a liner made of wool. Covers, yes, but not liners that I know of. I've also seen raw silk liners, or liners made of old t-shirts.
Another important function of a liner is to protect your diaper from rash creams.
Inserts: The different materials absorb at different rates and different amounts. Microfiber is cheap and absorbs quickly. That is why a lot of pockets use this material.
Hemp is usually great as a doubler not as an insert. Its very trim and absorbs a lot. However, it usually takes longer to absorb. So usually you want to use this with another insert, especially if you have a heavy wetter. Some people have had success just using hemp.
I haven't used bamboo yet, this is my next project. I've heard that it is relatively trim compared to microfiber, cleans well, absorbs great, and is supper soft.
Liners: There are paper liners, which people use so that they don't have to spray their diapers (just drop the liner and solids in the toilet and flush), or when they are using diaper creams (although I don't think this actually keeps all the cream off).
You can also use fleece liners to wick moisture away from the babies skin when using prefolds, flats, or fitteds. They can also be used when using diaper cream. But you want to make sure not to wash them with the rest of your diapers.
Can you elaborate on this? Do you put the wool right next to baby's skin or is it better in a pocket or under a liner? Is it meant more for absorbency or wicking wetness away?
You can wash liners with your other laundry, but you may not want to wash them with your diapers. It depends on why you are using the liner. If you are using liners as a stay-dry layer it's fine to wash them with your diapers. If you are using them to protect your diapers from rash creams they should be washed separate from your diapers to avoid getting the creams on the diapers. I usually just throw the liners in with a load of towels because I wash my towels on warm or hot.
you can put a wool liner directly on your baby's skin,that way your baby won't feel wet,and you can place a wool liner between the diaper and cover or used as an insert for pocket diapers for having an extra protection agains leaks.
I also know than the wool and silk liners are exellents to help baby's that have a bad rash.
the wool will keep them dry and the silk will help to sooth and calm the skin.
we know wool is an antibacterial and the silk is antiinflamatory.
but the only problem with this type of inserts is that you have to wash them by hand because,my wool liners got very small after a few washed on the machine and the silk the broke,you need to be careful on how to wash them.
