Any nappy consists of 3 layers. Each layer is made from a fabric designed
to perform a particular function.

Innermost Layer - Nappy Liner
Middle Layer - Absorbent Material
Outside Layer - Waterproof Material

NAPPY LINER
A liner is the layer in the nappy that sits closest to
your baby's skin. It can me made of a washable fabric
such as microfleece, polar fleece or suedecloth or a
paper-like disposable material. It performs 2
functions in the nappy:

1. It makes cleaning up a breeze. A flushable liner
'catches' any solid matter that can then be simply
dropped in the toilet. A washable liner is usually made
of either polar fleece or micro fleece. Both of these
materials allow most solid waste to just roll off the
fabric into the toilet.

2. It keeps your baby's bottom dry. Washable nappy
liners are particularly good at wicking moisture away
from your baby's skin into the absorbent layers. They
are also very soft, breathable and dry against
yourbaby's skin. A nappy liner is an optional addition
to your cupboard.

Note that fabric softener should not be used on
washable liners as this clogs up the liner so that
moisture will not pass through it.

nappy liners.
THE ABSORBENT LAYER
The absorbent layer is the part of the nappy that absorbs liquid. It can
either be a fitted absorbant layer such as the fitted nappy shown on the
right, or it can be a lay in absorbant layer. This means that you simply lay
the absorbent layer (usually a pad or folded square)) inside a waterproof
cover. Fabric softener should not be used on an absorbent layer. The
following materials are those that are most commonly used:

1.
Cotton Flannelette. This material makes a trim, cost effective nappy.
It is the least absorbent of the materials used.
2.
Cotton terry Toweling. This is the traditional material used for
nappies. It is more absorbent than flannelette but does make a bulkier
nappy. It can make a cost effective nappy depending on whether the cotton
is organic or not.
3.
Hemp. Hemp is very absorbent and also very trim.
4.
Microfibre. Microfibre is an exceptionally absorbent material. Since it is
so absorbent, it is questionable whether or not it should be directly against
your baby's skin. It is therefore recommended to cover the microfibre with
a liner. Microfibre is also very light, trim and quick drying. It is not a
natural fibre.
5.
Bamboo. Bamboo is also an exceptionally absorbent and trim material .
It also stays super soft after being washed and dried.

Boosters (Doublers, Extenders)
A booster is used to 'boost' the absorbency of a nappy and hence the
length of time the nappy can be worn. It is a piece of material designed to
sit snugly inside the nappy. A booster is especially useful for nighttime use
and for use when you know that your baby's nappy can't be changed for a
long time.
Again fabric softener should not be used on boosters as they are an
absorbent layer in the nappy.

Note that fabric softener should not be used on absorbent materials as this
clogs up the material reducing it's abilty to absorb moisture.
THE WATERPROOF LAYER
COVERS, SOAKERS
The waterproof layer can either be sewn into the nappy, or can be purchased
separately and used over the nappy - a cover. It is important to choose a
waterproof layer that allows your baby's skin to breathe. The most common
breathable waterproof fabrics are as follows:

1.
Polarfleece or Microfleece or Acrylic. These fabrics are water resistent
but not waterproof.They are useful as daytime covers when the baby is
moving around and the nappy is changed frequently. If compressed (for
example in a baby pouch), they may leak.

2.
PUL (Polyurethane Laminate). Laminated and coated fabrics are very
popular for use as a waterproof layer in a nappy. Regular fabrics are literally
laminated which results in a fabric which is completely waterproof yet
breathable.
PUL cannot be soaked in sanitizing solution as this affects the waterproof
properties of the fabric. Exposure to vinegar or bleach has the same affect.
PUL can be tumble dried on low for short periods of time, however it is a
quick drying fabric and it is therefore usually unneccesary to tumble dry.

3.
Wool.There are 2 types of woolen covers. A woven wool fabric is used to
make wrap style cover. Regular wool is used to make handknitted pull up
covers (soakers).
Wool covers are most popular for night use. This is because it is a
breathable, natural fibre. Since they neutralize odours and are usually used
once a day, they can often be used for quite a few days (even a couple of
weeks) before requiring a wash. As with fleece, they may leak if they are
compressed.
Wool works best if it is lanolized. This is a very simple procedure that
requires dissolving a small amount of wool fat (such as Lansinoh) in water,
allowing it to cool to lukewarm, and then soaking the wool cover in the water
for about half an hour. This is usually done after washing. Wool covers
perform best with lanolizing but should still work without lanolizing.
Woven fabrics can usually be machine washed on a wool cycle. Handknitted
soakers usually require handwashing. Wool should not be put in the clothes
dryer.
