How to increase the absorbency of washable diapers

The effectiveness of a washable diaper depends on its absorbency . If leaks occur or the diapers saturate quickly, the problem rarely lies with the model itself, but rather with the break-in period, care, or choice of fibers . This guide from Ma Boule de Couches® helps you optimize absorbency sustainably and naturally.

Why does the absorbency of cloth diapers decrease?

• Inserts not broken in or insufficiently washed before first use.
• Excessive use of laundry detergent, fabric softener or soap blocks capillary action.
• Laundry detergent based on glycerin, oil or coating agents.
• Incorrect combination of fibers depending on the type of baby's flow.

A simple adjustment of care or fiber is often enough to restore optimal absorption .

The break-in washing of the inserts: a key step

Before use, the inserts must be washed several times to remove the finishes and open the natural fibers:

• 3 to 5 complete washes are necessary for effective break-in.
• Use a mild detergent, without fabric softener or glycerin.
• Alternating washing and drying softens the fibers and increases their performance.

Choose the right fibers for better absorption

• Bamboo: very absorbent, perfect for nighttime or naps.
• Hemp: ultra-absorbent but slow, to be combined with a fast fiber.
• Tencel: ecological, soft and effective over time.
• Cotton: good balance between quick drying and absorbency.
• Microfibre: absorbs quickly but not much — to be protected with a Coolmax veil .

Caring for your washable nappies to preserve absorbency

• Avoid fabric softeners and harsh detergents.
• Wash at 40–60 °C depending on the soiling.
• Add an extra rinse .
• Perform a complete cleaning if there is a loss of absorption.

Tips to boost absorption

• Add a DouxBoost booster for the night.
• Check that the diaper is not too tight: compression reduces effectiveness.
• Alternate materials (e.g., bamboo + hemp) for optimal results.
• Dry in the sun to naturally regenerate the fibers.

Conclusion

To increase the absorbency of your cloth diapers, focus on three key areas: breaking in the inserts, choosing the right fibers, and using residue-free care. These simple steps will ensure dry nights and lasting comfort for your baby.
