More cochineal dyeing



These are the results of dyeing with ground cochineal using a recipe devised by Debbie Bamford which was based on one by Trudi Van Stralen. This recipe called for ground cochineal, which Debbie had supplied me with previously. The recipe called for 10% dye stuff per WOF : 5gms dye to 50 gms of fibre. The fibre used was a 50/50 blend of white silk/merino top, prepared for dyeing by plaiting lightly first in an attempt to prevent felting. The fibre was pre-mordanted in 8% alum and 7% cream of tartar. Stainless steel pot and soft tap water were the other elemnts involved in the dyeing process.
There was a lot of dye left in dye bath. Hard to rinse dye from fibre, so required multiple rinsings. Even ended up not fully rinsing all remaining dye out for fear of felting. However fibre felted anyway. Might be able to use it for novelty yarns....
