An Azo Free Yarn Cone refers to yarn that has been dyed without the use of azo dyes, which are synthetic colorants known to release potentially harmful aromatic amines. These substances have been linked to skin irritation and even carcinogenic effects, which is why many countries, including those in the European Union, have restricted or banned their use. By avoiding these compounds, azo-free yarns are considered safer for human contact and more environmentally friendly.
