Many people ask us why our sweaters have acrylic in them. The reason is that when we recover the remnants, they are composed of wool and different types of acrylic. This is the material we use to recycle and make yarn again (it would be impossible to separate the two types of fiber in a mechanical process).
On the other hand, for the time being, it is not possible to achieve adequate yarn twist using only recycled wool fibers. In the case of IAIOS, all the fibers we use (acrylic and wool) are recycled.
This system allows us to avoid the dyeing process (we simply separate the remnants by shades and then grind and mix them to find the right colors) and we use only 1% of the water used in a normal spinning process.
We would also like to emphasize that acrylic does not necessarily have to be an artificial and harmful material. In fact, it can be more sustainable depending on how it is used. For example, it is much easier to recycle than other types of materials (even several times). It also gives the yarn strength and durability, which gives a longer life to our clothing.
NOTE: all the fibers we use in our yarn (acrylic and wool) are recycled.
