Traditionally derived from materials such as oak galls, oak bark and leaves, tannic acid provides the tannins needed to help natural dyes bond more effectively to plant fibres.\u003c\/p\u003e\n\u003cp\u003eIn natural dye processes it is often used alongside mordants such as alum or aluminium acetate. The tannin treatment prepares the fibre so that the mordant and dye can attach more strongly, resulting in deeper colour, improved fastness and more even results.\u003c\/p\u003e\n\u003cp\u003eThis high-quality powder (86%+ purity), extracted from gallnut and oak sources, dissolves easily in water and performs consistently across a wide range of dyeing techniques. Used correctly, it helps cellulose fibres hold natural dyes far more effectively than dyeing alone.\u003c\/p\u003e\n\u003cp\u003eOutside of textile dyeing, tannic acid is also known for practical uses such as helping remove rust from metal surfaces.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBenefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eImproves dye adhesion on cotton, linen and other cellulose fibres\u003c\/li\u003e\n\u003cli\u003eWorks alongside alum or aluminium acetate mordants\u003c\/li\u003e\n\u003cli\u003eHelps achieve deeper, more colourfast natural dye results\u003c\/li\u003e\n\u003cli\u003eHigh-quality 86%+ purity gallnut\/oak-derived powder\u003c\/li\u003e\n\u003cli\u003eAlso useful for rust removal applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003ePerfect For\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eNatural dyeing with plant dyes on cellulose fibres\u003c\/li\u003e\n\u003cli\u003eBotanical dye workshops and eco-printing projects\u003c\/li\u003e\n\u003cli\u003eEducational and professional textile dyeing setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e100% natural oak bark and leaf extract (tannin source)\u003c\/li\u003e\n\u003cli\u003eUsed as a primary tannin mordant for cellulose fibres\u003c\/li\u003e\n\u003cli\u003eEnhances colourfastness and saturation in natural dyeing\u003c\/li\u003e\n\u003cli\u003eIdeal for use before alum mordanting for best results\u003c\/li\u003e\n\u003cli\u003eDissolve in warm water, soak fabric, rinse lightly, then proceed to mordant bath\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Kraftkolour","offers":[{"title":"Default Title","offer_id":51912862564616,"sku":"L.ND.TAN","price":10.4,"currency_code":"GBP","in_stock":true}],"url":"https:\/\/winghamwoolwork.co.uk\/products\/natural-dye-tannin","provider":"Wingham Wool","version":"1.0","type":"link"}
