As shown on the figure to the left, it is estimated that 11% of the (cradle-to-factory gate) carbon footprint of a 100% polyester ladies top is due to the yarn dyeing stage [1].

Solution dyeing eliminates the need for the yarn dyeing stage for synthetic fibres. It has potential to provide significant energy and water savings [2] as well as carbon emissions and waste water production. Further life cycle assessment research is needed to quantify these benefits in practice.
