Parts of a Diaper

Diapers are made up of four layers; each layer is made from different components. For each part, the damage is unique and occurs at its own time. The four layers of the diaper are:

Top Sheet

The diaper’s top sheet layer is the layer that is in direct contact with the baby’s skin. It acts as a barrier against the urine and allows it to stay inside the diaper for absorption. It is specially designed to transfer the fluids to the diaper’s core layer, keeping your baby dry and fresh. Most diaper manufacturers use polypropylene and polyethylene as lining, and both are considered safe for the little ones. Some companies use moisturizing ingredients in the top sheet that keep the baby’s skin smooth, hydrated, and free from rashes.

Absorbent Inner Layer

The absorbent layer, also known as the inner layer, contains extremely absorbent polymer sodium polyacrylate, absorbing all the liquid. It is an absorbent that can soak up fluids a lot more than its weight, which makes it perfect for baby diapers. It helps in keeping the diaper thinner and the baby’s skin dry. The absorbent layer is skin-friendly and allows the water vapor and air to flow freely, making your baby carefree.

Waterproof Outer Layer

This layer is made from a soft water-resistant material that feels soft against your baby’s skin. This layer is made from petroleum-based plastic that holds in liquid and prevents it from leaking out. Prints and cartoons made on the outer layer and the diaper manufacturers ensure that the ink used is safe for the baby’s skin.

Fit and Comfort

This diaper feature varies from one manufacturer to another, but each performs the same essential function. The fundamental feature is the side stretch which hugs the baby’s torso and prevents the fluid from leaking. The elastic sides ensure the conform of the baby and keep him active all day long.

Effects of Time on A Baby Diaper

You will notice in old diapers that they are not as bright as they used to be. This is because the diapers are paper product and, just like any other paper item it also turns yellow when exposed to oxygen. Other than that, if the outer layer has some prints on it, they will also fade. The diaper might look unappealing, but this does not damage the inner functioning of the diaper.

Lesser Absorption

The component responsible for soaking up fluids in the diaper’s inner layer is sodium polyacrylate. This component absorbs moisture from the air when the diaper is exposed to air. This does not mean that the diaper is expired. It just means that the tendency to absorb urine is reduced, and your baby might leak more often.

Change in Fragrance

Another thing about old diapers is that they do not smell as pleasant as they used to when you first brought them. The fragrance molecules break down over time, leaving the old diapers with less fragrance.

Less Elasticity

As the diapers get old, it loses its elasticity. Spandex, a material used in the waistband and leg cuffs, is resistant to heat and moisture. Still, another material is added to it, like rubber or latex, then it might break down and lose elasticity. If the diaper is ill-fitted, it will not perform its functions properly, it will not say in place, and your baby will leak, leaving you and the toddler more anxious.

Some of the tips that can make the disposable diaper last longer:

  • Store the diapers in the dark ventilated cabinets where the above factors cannot influence them.
  • If the package is unopened, let it remain unopened. If they are already opened, you can add the diapers in an airtight, vacuum-sealed bag.
