If more absorbency is needed, here are some options.
- Cotton flats, prefolds, muslin cloth, trifolds, tea towels, face washes. These are cheap, easy to wash and dry quickly.
- Bamboo or help inserts and trifolds, these absorb a lot.
- Microfiber inserts. These are like sponges, liquid will absorb but it will start seeping out once compressed.
Microfiber on top of bamboo insert/hemp/cotton flat/cotton tea towel/a prefold/ trifold works well. The insert below catches any compression leaks from the microfiber that sits on top. Microfiber should not go directly against the skin, it can cause irritation.
If more absorption is needed use any of the options above, bamboo, hemp and cotton absorb more liquid than microfiber.
Some absorbency measurements:
Bambino Mio size 1 prefold 110g
Bubblebubs cotton muslin flat 70x75cm 150g
Designer Bums small snap in insert 65g large anchor insert 145g
Real Nappies Crawler prefold 251g
Econaps small insert 60g large insert 85g
Dickies Terry Towelling Flat 282g
IKEA Haren hand towel 250g
Alva 3-layer bamboo insert 115g
Bamboo trifold inserts 180g
IKEA 70x70cm muslin (from baby section) 195g
Inserts made from bamboo, hemp or cotton can be soaked overnight to help increase absorbency and then washed on a regular cycle with detergent. These fabrics will continue building absorbency with use, change more frequently during this time.
Why does prepping make such a difference?
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 , .
Covers and microfiber inserts can be washed once with detergent prior to use.
