Cloth Nappy Anatomy - Definitions and Fabrics

Explaining the parts of a cloth nappy

 

Just started looking into cloth nappies?  It can be overwhelming and confusing.  So many abbreviations, so much lingo!  Well, hopefully this information will help you out a bit.

Any nappy consists of 3 layers and 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 be 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 which allow most solid waste to just roll off the fabric into the loo.

2. It keeps bub's bottom dry. Washable nappy liners are particularly good at wicking moisture away from your baby into the absorbent layers. They are also very soft, breathable and dry against your baby's skin. A nappy liner is a helpful but 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.

Here are some instructions on how to make your own nappy liners.

THE ABSORBENT LAYER

Absorbers (Inserts)

The absorbent layer is the part of the nappy that absorbs liquid. It can either be:

• a fitted absorbent  layer, which is sewn into shape, such as the fitted nappy shown above
• an insert, sliding between the liner and waterproof layer, as in a pocket nappy
• or it can be a 'lay in' absorbent 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:

• Cotton Flannelette: This material makes a trim, cost effective nappy. It is the least absorbent of the materials used.
• 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.
• Hemp: Hemp is very absorbent and also very trim.
• 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.
• 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, on a long drive, for example.
Again fabric softener should not be used on boosters as they are an absorbent layer in the nappy.

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 very quick drying fabric and  so it is usually unneccesary to tumble dry.

3. Wool.There are 2 types of woolen covers. A woven or felted 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.

Baby Beehinds Magicall All in One Cloth Nappy Review

About time for another nappy review, I think :) And next in line according to the votes is the Baby Beehinds All In One.  First up, I've got to say that these are one of my go to nappies when we go out and I want something cute and reliable. They're easy, trim, and I know that apart from the worst poo-plosions I don't have to worry about leaks.
Ok, so into the review.

Purple: small on 5mth old ~ Red: medium on 2yr old

Features:
PUL outer in smooth or minkee

Inner and pocket - excuse the bad lighting - it's not that stained! ;)

Micro suede inner
2 layers of microfibre sewn in with a pocket behind
 Bamboo booster included
Leg gussets
Velcro or snap closure
Sized S, M, L

First impressions: 
Great quality, as all Baby Beehinds products are.  Good thick PUL, strong elastic, soft minkee.  Gotta love 'em!  You don't see many nappies with leg gussets like these ones.  The leg elastic is in a little from the edge of the leg hole fabric creating a flared effect, like a flower around bub's leg.  That may sound a little strange, but it's saved my girls' clothes from escaping poop numerous times! ;)

Size/ Fit:
The best thing about sized nappies is the trim fit and lack of tummy bulk and these are no exception.  They're not the trimmest nappy around, but for the sake of reliability, I'll take the extra height and leg gussets any day!  The overlapping snaps allow for good tummy adjustment on a newborn, but I did find that the leg holes on the small took a little growing into, but that does also mean that my chubby 2 year old still squeezes into her mediums :) 

Absorbency:
The 4 layers of microfibre sewn into the nappy were enough for Cha Cha for the first couple of months, but now that she's almost 6 months she needs the included bamboo booster in her smalls.  She wets through almost anything, though, so I'm getting the feeling she might be a heavy wetter.  Lou Lou, on the other hand still only needs the included booster in her mediums even though she's now 2.  The mediums have a larger section of microfibre and a larger booster pad, but I'm wondering if Cha Cha might need more than that.


Washing/ Drying:
I love that there are only 2 pieces to wash and dry.  I turn mine inside out so that the sewn in microfibre gets a good wash and sees some sun, and hang them sideways or in the middle to save the leg elastic.  Because there are 4 layers sewn in they do take a little longer to dry, but not much longer than a bamboo trifold.

 Summary:
These really are one of my favourite nappies.  I got mine second hand and they're still going strong and wearing really well.  Most of mine are minkee with snaps, but I do sometimes wish they were velcro when bub's wriggling round on the table :)
