Dylon Fabric dye, MACHINE WASH fabric dye - for dyeing textiles in the washing machine. Dye a solid-coloured garment or use batik knots to create a brand new style! Cotton, linen and viscose will have full colour strength up to 600 g. Polyester/cotton & polyester/viscose blends will have lighter shades (wool, silk, synthetic fibre and fabrics that require dry-cleaning cannot be dyed). The original colour of the fabric always impacts the end results; it is hard to turn a dark fabric into a light, bright colour. Wash fabric before dyeing. The fabric should be damp when placed in the washing machine. Dye 600 g fabric max and do not fill machine more than half full; otherwise stains may occur. Choose the longest programme at 40°C. Remember not to use programmes in which the washing machine uses less water than usual, which can produce uneven colouring. Instructions enclosed. Withstands washing at 40°C after dyeing. Salt included. Pack of 350 g.
