Wool is naturally antibacterial. This is due to its lanolin (wool fat) content - as wool becomes moist, some of the lanolin converts to lanolin-soap, which helps keep the fabric hygienically clean! Combining this with it's self-cleaning properties, you can begin to understand why wool underwear doesn't get smelly. It smells fresh for ages.
Wool can absorb around 33% of its own weight without feeling wet. This is heaps more than man-made fibres, which typically absorb only 4% before feeling wet and uncomfortable. It's much more than cotton, too. It means that your baby is more likely to stay warm and dry if he/she dribbles or possets, and you can just give a quick rub down rather than having to change him/her so often. Making your baby happier, and your life easier.
Wool is a great insulator. It is warm in winter and cool in summer (think vacuum flask). This is because of all the "waves" in the fibre, which lock in air. It may seem strange to us to use wool in the summer, but many Bedouins and Tuaregs use wool to keep the heat out! (They use camel and goat hair as well as sheep's wool.) This is why sheepskins are such a great choice for prams, strollers and carseats, keeping your baby comfortable and so making your life easier.
Wool is "bouncy" - the springiness of the fibres gives it good elasticity - it stretches really well and goes back into shape well too. This means that it's very easy to put on your baby - and to take off of course too. Much less fiddling around with arms and things. Making your baby happier, and your life easier (did I say this before?).
Wool fibres can be bent and twisted over 30,000 times without breaking. (That's just an interesting fact. I can't relate that to your baby...)
Finally, wool is a very safe fabric and fire-resistant. It's harder to ignite than most synthetic fibres and cotton. It has a low rate of flame spread, it doesn't melt, or drip, and if it does burn it creates a "char" which self-extinguishes.
Bamboo fabric is a natural textile made from the pulp of bamboo grass. The Bamboo used to produce fabrics (not the same as Panda food) is easily replenished and requires no pesticides to grow. Bamboo is considered one of the most sustainable plants because it grows quickly and does not require chemicals or irrigation, and biodegrades more quickly than oil-based synthetics. It also has anti bacterial properties.
Bamboo rayon is made by dissolving pulp bamboo into its cellulose component and then spun into viscose fibers. Clothing made of bamboo rayon typically lasts even longer and holds its shape even better than clothing made of simple bamboo fiber.
Organic cotton is grown using methods and materials that have a low impact on the environment. Organic production systems replenish and maintain soil fertility, reduce the use of toxic and persistent pesticides and fertilizers, and build biologically diverse agriculture. Third-party certification organizations verify that organic producers use only methods and materials allowed in organic production. Organic cotton is grown without the use of toxic and persistent pesticides and synthetic fertilizers. In addition, federal regulations prohibit the use of genetically engineered seed for organic farming. All cotton sold as organic in the United States must meet strict federal regulations covering how the cotton is grown.
