The materials used in the cloth diapers you choose for your baby are equally as important as the style of diaper you choose. The following is an explanation of some of the most commonly used diaper materials:
Waterproof Layers are commonly made of materials such as PUL (polyurethane laminate) and TPU (thermoplastic polyurethane), the waterproof layers of cloth diapers obviously perform very important functions that most parents will not want to do without. While the processes used to create these fabrics are way too complex for most of us to understand, there are two key questions that you may want to ask the manufacturer of your diaper:
There are a wide variety of materials - sometimes used in combination with each other - used to create the absorbency layers of cloth diapers. The following list details the major materials used, with some of the key features and issues associated with each:
Bamboo - Bamboo fiber is an incredibly absorbent material and naturally resistant to bacterial growth, making it an excellent fabric for diapering. The bamboo plant is incredibly fast growing and therefore is often farmed with little negative impact on the surrounding ecology. However, the process of converting bamboo wood into the soft and absorbent fiber that is found in diapers is an incredibly complex and harsh chemical process that does have negative side effects, for this reason the labeling of bamboo as an organic material is misleading.
Cotton - Cotton is the most commonly used plant based fiber on earth. Because of its incredible popularity and many uses, cotton production is a major industry, and not all cotton is created equal. The cotton industry does use GMO cottons that can be harmful to farmlands and the surrounding environment in an effort to meet demand. To seek out a cotton that is the most ecologically responsible in production, and to guarantee that your child's diapers are not made of GMO cottons you will want to check for organic certification of the fabrics. For example OEKO-TEX® Certification is considered the gold standard in textiles that are free from harmful substances. Read more about IMO Certified Organic Cotton.
Hemp - Hemp is a natural fiber that is more hydroscopic than cotton and naturally resistant to bacterial growth. Hemp materials are quite thin while still absorbent, but they do not absorb as quickly as cotton or polyester. For this reason, in diapers, hemp fabric is often paired with another absorbent fiber, such as in a hemp/cotton blend.
Modal - Modal fabric is similar to bamboo in that it is made from wood pulp, however it is made from the wood pulp of beech trees rather than bamboo. Modal has an incredibly silky feel to it, and maintains its softness and wears well over time. One key advantage to modal fabrics in diapering is that they are resistant to the mineral build up that many struggle with when washing diapers in hard water.
Polyester - Polyester is a man made material, and as such is made with chemicals and petroleum. In diapering the word "polyester" is often replaced with "microfiber," "minky," and occasionally "zorb". These products are quite absorbent, but they do wear out over time, loosing the ability to absorb with continued wear. Microfiber is often used in pocket diapers and should never be used directly against a baby's skin as it can be irritating. The microscopic structure of these fibers that makes them so absorbent can also make them incredibly difficult to get thoroughly clean with each washing, and therefore tend to develop odors over time.
The porous and water-resistent properties of the following fabrics allow for them to be used in unique ways for cloth diapering.
Fleece - Polyester fleece comes in many weights and varieties and can perform several different functions. The thinnest fleece is often used on the interior of a diaper as a stay dry layer, as described further below. Thicker fleeces can be used in making a breathable cover for diapers. If there is a very absorbent diaper underneath, fleece can be an incredibly successful fabric as a cover for diapers since it is so water resistant, yet porous for breathability. It is often sewn into "soakers," "shorties," and "longies" at home for economical and adorable diapering. Fleece does vary in quality however, and can be prone to compression leaks when used in a car seat or baby carrier for an extended time.
"Stay Dry" Fabrics - Suedecloth, microfleece, and athletic fabrics - which are porous polyester fabrics - are frequently used in diapering as a "stay dry" layer. These fabrics are not designed to absorb liquids, so when used inside a diaper as the layer closest to a baby's skin the urine passes through them and into the absorbent layers of the diaper. This helps to keep moisture away from a baby's skin longer, helping the skin to "stay dry."
Wool - Wool is the most natural and breathable material available for use in diaper covers. It is naturally resistant to bacterial growth and when lanolized it is incredibly water resistant. Wool interlock fabric, as well as knit and crocheted items, all require hand washing and lanolizing but many who use wool as their choice for diaper covers find the benefits of wool to be worth the higher maintenance of the material. A wool cover paired with an absorbent fitted diaper is a very breathable choice and is popular for children who are more rash prone as well as for night time diapering.
Modern cloth diapers come in many varieties so that each family can find exactly what works for them. Considering the source of your diapers, and which fabrics you most want wrapped around your baby is an important part of cloth diapering as you will be reusing the diapers many times over the next few years.
