New Nappies

Prior to first time use, inserts made from bamboo, hemp and cotton can be soaked overnight to help increase absorbency and then washed on a regular cycle with detergent, in water of any temperature. These fabrics will continue building absorbency with use, change more frequently during this time to prevent leaks from occurring.

Why does prepping new nappies make such a difference to user success?

The surface area of the fibers increases over time with washing (ie friction), the fibers become looser and micro piling occurs. The greater the surface area, the more absorbency potential [1], [2].

Covers and microfiber inserts can be washed once with detergent prior to use.

See the Adding Absorbency page for absorbency measurements of various flats, prefolds and inserts.
