WALNUT LEAVES DYE

Walnut Leaf Natural Dye Juglans regia L. · Cut or Powdered Walnut leaves are a traditional botanical dye material producing muted golden yellows, warm tans, camel shades and earthy browns. The leaves contain naturally occurring tannins, flavonoids and naphthoquinone colourants. They generally extract more readily than hard walnut shells and can provide useful colour without requiring fresh green walnut husks. Choose cut leaves for easier straining and slower extraction, or powdered leaves for quicker colour release. At a glance Feature Details Botanical name Juglans regia L. Plant part Dried leaves Forms Cut or powdered Latin trade name for powder Juglandis Fol. pulv. Material Raw botanical dye material - not an extract Colours Muted gold, golden tan, camel and warm brown With iron Olive-brown, taupe, grey-brown and deeper earthy shades Fibres Wool, silk, cotton and linen Best affinity Wool, silk and other protein fibres Colourfastness Generally good when suitably prepared, dyed and finished A naturally tannin-rich leaf dye Walnut leaves contain a mixture of tannins, flavonoids and other phenolic colourants. Protein fibres generally develop the strongest shades. Cotton, linen and other cellulose fibres require suitable preparation for more reliable colour uptake and durability. Because this is a natural leaf material, colour strength varies according to the cultivar, growing conditions, harvest season, drying and storage. Choosing a form Cut walnut leaves Suitable for overnight soaking and gentle extraction Easier to contain and strain from the dye bath Well suited to longer extractions May be extracted again for a paler second bath Powdered walnut leaves Finely powdered dried walnut leaves Greater surface area encourages quicker colour release Produces more sediment than the cut form Best contained in a fine cloth or dye bag Requires regular stirring to prevent settling and scorching The powdered form is made from the same dried walnut leaves. It is not a concentrated extract. How much to use For lighter golden tan and camel shades, begin with: 50–100g dried walnut leaves per 100g dry fibre Equivalent to 50–100% WOF - weight of dry fibre. For stronger warm brown shades, use: 100–200g dried walnut leaves per 100g dry fibre Equivalent to 100–200% WOF. Powdered leaves may release their available colour more quickly than the cut form, but the same starting quantities can be used. These quantities are starting points. Sample first when working towards a particular result. Basic dyeing guide Prepare: Scour and prepare the fibre using a method appropriate for the fibre type. Wet the fibre completely before dyeing. Soak: Cover the walnut leaves with water and leave overnight. Powdered leaves may require less soaking but still benefit from thorough wetting. Extract: Heat gently at approximately 80–90°C for one hour. Avoid vigorous boiling. Strain: Strain the liquid through a cloth. Powdered leaves are best contained inside a fine dye bag or strained through a closely woven cloth. Dye: Add the prepared fibre and hold the bath at approximately 80–85°C for one hour. Deepen: Allow the fibre to cool in the dye bath or leave it overnight. Finish: Rinse thoroughly and wash gently. Avoid vigorous boiling, particularly when working with wool or silk.

Tips from the dye pot Tip Details Match the form to your process Cut leaves are easier to strain and suit longer extractions. Powdered leaves release colour more quickly but create more sediment. Contain the powder Keep powdered leaves inside a fine cloth or dye bag whenever possible. Stir regularly Loose powder can settle and scorch if left undisturbed on the bottom of the pot. Protect protein fibres Use gentle heat and avoid prolonged vigorous boiling when dyeing wool or silk. Consider alum An alum mordant can encourage clearer golden and warm brown shades. Shift with iron Iron moves the colour towards olive-brown, taupe, grey-brown and deeper earthy shades. Begin with approximately 1–3% WOF. Use iron carefully Iron acetate is generally gentler on fibres than ferrous sulphate. Excessive iron can dull the colour and weaken fibres over time. Expect variation Cultivar, growing conditions, harvest time, drying and storage affect the strength of the leaves. Keep notes Record the fibre, preparation, mordant, water chemistry, dye quantity, temperature and processing time. Colourfastness Walnut leaf dyes have produced generally good wash, rubbing and lightfastness results under suitable dyeing conditions. Studio performance still depends on the fibre, preparation, mordant, depth of shade, extraction method, water chemistry and aftercare. Protein fibres generally take walnut leaf dye more strongly than cellulose fibres. Cotton and linen require careful preparation to achieve reliable results. Storage and safe handling Store sealed in a cool, dry place away from direct sunlight. For textile dyeing, paper and craft use only. Not for consumption or use in food, drinks, cosmetics or herbal preparations. Avoid creating or breathing dust, particularly when handling the powdered form. Work in a well-ventilated area when handling fine powder. Prevent contact with the eyes, mouth and open wounds. Wear suitable protective equipment when handling dusty material. Walnut and its naturally occurring compounds may cause irritation or an allergic reaction in susceptible individuals. Follow the safety instructions for every mordant and modifier used. Use dedicated dyeing utensils and containers - never food-preparation equipment. Keep away from food, children and pets.
