Main constituents: flavones (luteolin, apigenin) + tannins + other coloring molecule.

Uses :
Natural dye & textile printing : this plant extract allows to dye any type of fibers. It does provide more intense colors on mordanted wool. Indicative shades depend on the recipe and mordant : Yellow-straw (aluminum mordant), grey-brown in the presence of iron, orange light in the presence of titanium. This extract provides a good lightfastness.

Other uses : Medicinal plant: the leaves and stems of thyme are traditionally used for symptomatic treatments of digestive disorders, coughs and as a mouthwash. The essential oil is used in the formula of various pharmaceutical specialties and is widely used as an antiseptic in aromatherapy. It is also present in the perfumery and hygiene products sectors. Aromatic plant: the leaf and dry flowering tops of thyme are used in the food sector and in many culinary preparations. It is also an excellent honey plant.
Not suitable for food use.

The plant : Thymes are sub-shrubs with woody, tortuous and very branchy stems, bearing small pale pink or white flowers. They are perennial plants of the Lamiaceae family. Thyme is very resistant. It needs sun and grows wild on the arid and rocky hills of the Mediterranean regions up to 1,500 to 2,000 meters above sea level. The plant is found in Western Europe. It is also established in Eastern and Southern Europe.
The essential oil is obtained from fresh flowering aerial parts. The essential oil content varies from 5 to 25 ml/kg and its composition varies depending on the chemotype.

Co-products and upcycling : based in the South of France, GREEN’ING is committed to develop natural colors from local plants and valorize agro-industrial co-products. This thyme extract is a perfect example, resulting from GREEN’ING’s research and development in extraction from distillation by-products and aromatic herb sectors. A new example of proximity between the dye plant sectors and PPAM, a source of bio-economy.
It is one of the basic ingredients of the new range of extracts that we offer in warm and varied colors from Occitania.

Main constituents: hydrolysable tannins > 95%

Use : Pre-treatment and mordanting of vegetable fibers: Plant tannins is very rich in tannins. Tannic acid allows the pre-treatment of cellulosic plant fibers (called engallage in this case) in order to improve the fixation of the mordant during mordanting. THIS TANNIN PROVIDES A LIGHT COLOR.

Natural dyeing and textile printing : all fibers can be dyed with PLANT TANNINS. The colors obtained have slightly better lightfastness.
For bright colors, it will be used in the first bath followed by the mordant of aluminum salt. We recommend the ALUMINUM LACTATE, manufactured from renewable raw materials. In the presence of FERROUS SULFATE or FERROUS LACTATE (shading process after tannin), this extract forms very solid and dark complexes, to create numerous grey shades grays. In the presence of TITANIUM, a bright orange is obtained.

Not suitable for food use.

Uses : Natural dyeing and textile printing : this plant extract allows to dye any type of fibers, mordanted or not. The tannins of gallic type (tannic acid = hydrolyzable tannins) naturally bind to cellulosic fibers. The shades are obtained depending on the concentration of bath and mordant : beige, fawn (not mordanted or aluminium), greys in presence of iron, orange in presence of titanium. This plant was part of the recipe of Noir de Bédarieux, our city. It was also used and described in the recipes of Paul Gout’s 157 colours or those of Antoine Janot’s 85 colours.
Other uses : Tannery.
Do not use for food.

The plant : Coriaria or Redoul (litterally ‘myrtle-leaved corroyere’, Coriaria myrtifolia L.) is a common species in the South of France and Catalonia. This shrub which has leaves similar to myrtle and can be 2-3 m height, is present along paths and rivers. WARNING: the fruits of this plant are very toxic and can sometimes be confused with brambleberries. The literature also indicates that the aerial parts are toxic. We have carried out research and analyzes which show that the most toxic parts are the seeds (the fruit pulp is much less so). Our extract is made from material without any fruit, using an optimized extraction process and our analyzes demonstrate that toxic molecules are only detected in trace amounts in the extract.

Historical uses and Noir de Bedarieux : Redoul or coriaria has been known and used since the Middle Ages in the South of France and in Catalonia. Narbonne and Montpellier were by far the largest importing centers for Catalan corroyère in Languedoc. During the first half of the 14th century, the city of Montpellier, the main center of demand, was gradually overtaken by Narbonne. Its name comes from the Latin corium or corroyage, indicating its use for tanning hides, its first use. Redoul is the basis of one of the technical innovations of the Languedoc and Catalan cloth dyers of the Middle Ages: it made it possible to obtain a beautiful black by giving a second dye with tannins and iron salts to a sheet which had already received a “foot” of pastel which could, in this case, be significantly less intense. Closer to us, books on the chemistry of dyes from the 19th century describe the production of Noir de Bedarieux, of which redoul is the main ingredient. GREEN’ING being located very close to Bédarieux, it was obvious for us to revive this color.

Main constituents :luteolin, flavones (minor – apigénine, chrysoeriol).
This natural dye extract does contain nearly 51% more of natural color than our traditional extract. Deep yellows obtained at pH 8.0.

Uses :
Natural dyeing and textile printing : Weld extract is from the main European dye plant resource for yellow shades. It can be used with any kind of fiber, combined with any mordant and most other dye extracts to obtain a very wide range of lightfast colours. For deep yellows, this dye develops best in slightly hard water – for example by adding  sodium carbonate or calcium carbonate (chalk) for instance to set up your bath to pH 8.0.

Products not intended for food or dietary supplements.

The plant :
Weld or Dyer’s weed (Reseda luteola L.) is one of the most oldest dye plants used for yellow colour. It was classified as “grand teint” (color fast). The whole plant is a good source of natural dye, except the root. It was used as a natural dyestuff since the Roman Antiquity or Prehistoric times. Its use widely spread from the Middle Age and weld was grown in England, in France, in Belgium and in the southeast of Germany.

Use :
Natural dye – mordanting and nuancing any fibers : iron is the basis of all grey and black shades by reaction with natural tannins. In a general way, it is used to darken colours and make them deeper. It slightly improves light- and wash-fastness from those obtained with aluminum mordants. Recommended use at 1-3 % of the Weight Of Fiber (WOF). A higher % may alter the structure of proteinaceus fibers and make them breakable.

For grey and black shades, we also recommend to use our extracts of logwood, oak gallnut, sumach gallnut, tara, acacia. The best results will be obtained with combinations of these extracts.

Also, combinations of aluminum and iron mordants or a last (very light) iron bath after a aluminum-mordanted-colour will widely increase the number of shades.

Use :
Natural dyeing – mordant recommended for cellulosic fibers : This mordant is used in the same way and in the same proportions as aluminum acetate for the natural dyeing of cellulosic fibers. Its solubilization is complete at room temperature. The colors obtained are intense.

As a preliminary step, we also recommend a first bath of a low coloured tannin (oak gallnut, sumach gallnut or tara) or with a tannin that will bring a light background color (acacia, myrobalan, chestnut).

Use :
Textile dyeing : the natural indigo dyes provide ranges of blue shades, from very clear to dark, with a very good lightfastness and washfastness. Their use in textile needs to turn them from an oxidized state (blue pigment, insoluble) to a reduced state (greenish yellow pigment, soluble) which will allow to fix on fibers before being again oxidized (by the oxygen of air – a magic step that develops the blue color). These reactions can be processed in natural vats by using our fructose syrup and hydrated lime for instance (1-2-3 vat type) or by using a chemical reducing agent (sodium hydrosulphite or thiourea). The natural indigos can be easily combined with other dye extracts (yellow, red for example) to widen the range of shades (green, purple…).
Instructions and downloads : Preparation of indigo vats & dyeing instructions, advanced information on indigo natural vats (only in French, sorry).

Paintings, decoration, fine arts : the indigo is then directly used as a natural pigment, after homogenizing into the selected binder or medium. It may be necessary to grind the pigment into the medium in order to develop the colour and avoid big particles.

Other uses : cabinetmaking, ink.
