FD15600Fixitol POtherwise known as ‘Retain’, Fixitol P canbe used to improve wash fastness and boostcolourfastness, particularly in deep shades andis suitable for use with most dyes.250ml£5.50 ................... ED706/111Jacquard Sun BlockerAdd to the wash cycle to help block theharmful UV rays which fade and bleach dyedfabrics in the sunlight.14g£3.55 ........................

As a humectant it retainsmoisture even when dried, and this boosts thecolour yield of the dye during the fixing stage.Use with Manutex or sodium alginate thickenerwhen printing, painting or applying dyes directly.500g£4.60 ..........................

Mordanting materials beforeand after dyeing with natural dyes will addextra fastness. The quantity of mordant usedwill vary depending on the fibre content, themethod used and the desired colour result.The mordant sample pack contains sufficientmordant for a range of dyeing experiments andincludes 250g alum, 50g iron and 10g each ofchrome, copper and tin.£9.50 FD14600Alum (potassium aluminium sulphate)500gAluminium Acetate100gAmmonium Sulphate500g£6.65 .......................
