3D Merino colour is an extra dimension for Merino wool knitwear caused by milling or felting being limited to specific areas creating a subtle pattern. The felted and non-felted areas vary in thickness giving a 3-Dimensional aspect. A wide range of colours can be overlaid on the 3D fabric by the same process of screen printing.
Knitted fabrics or garments are screen printed using a colourless polymer along with acid or reactive dyestuff.
The polymer is a polyurethane which is capable of preventing wool knitwear from milling or felting. The polymer is applied from a thickened print paste which prevents spreading and loss of definition and is fixed by heat curing or batching for 10 to 12 hours at room temperature.
Subsequent washing causes felting or milling in the non-printed areas which creates a subtle pattern on the fabric.
If felting is taken to the limit then seersucker effects can be created.
