Tara Extract 1kg (2.2 lb.)

Tara Extract is colourless and high in tannins. It is used to mordant cellulose fibers and fabrics before the alum mordant is used. It is also used in the leather industry to obtain very bright and light coloured leathers. Use at 15% WOF.

Tannin

Tannic acid is used to assist the mordants of cellulose fibres and fabrics. Alum does not bond with cellulose fibres as well as it does with protein fibres. However, tannin bonds well with cellulose. and once treated with tannin, alum will combine with the tannin-fibre complex. Many dyestuffs contain tannin (black oak, pomegranate, cutch, fustic, etc) and do not need an additional tannin.

Tannins can be clear or they can add colour to the fibre, and this is an important consideration when selecting a tannin. 

•  Clear Tannins: “Gallic” - Gallnut, Tara, some Sumacs

• Yellow Tannins: “Ellegic” – Myrobalan, Pomegranate, 

•  Red-Brown Tannins: “Catechic” – Cutch, Quebracho, Tea leaves, and some Sumacs.
