Isager Sock Yarn consists of 40% Easy Wash Alpaca, 40% Easy Wash Merino Wool and 20% Recycled Nylon. The quality has a good durability, gives a soft result and can be machine washed. Easy Wash is the environmentally-friendly alternative to the standard chlorine process used to make the fibres machine washable without shrinking. The Easy-Wash process is a treatment with eco-friendly oxidants, this means that this treatment does not involve the discharge of hazardous chemicals, which is not the case with most machine washable yarns in today's market. 20% of the fibre content is recycled nylon which provides strength to the yarn. For the first time Isager is using a synthetic fiber in a yarn, but it was impossible to find a yarn in natural fibres only that offered softness and comfort, and at the same time was strong enough to offer the durability required for a sock yarn.
