NATURAL DYEING
Dye-plant extracts & mordants in small packages for your own natural dyed textiles. Our extracts are manufactured from plants locally grown in France or from selected raw materials (plants or extracts from mild regions). More information on our products Dyeing with plant extracts Dye-plant extracts Couleurs de Plantes® will provide you a large range of beautiful shades on natural fibres ( silk, wool, linen, hemp, ...) and can also be used with some synthetic fibres (polyamide...). Blue or marine shades are mostly obtained from natural indigos (and through a different dyeing process). Advices and instructions Two kinds of natural dyes are available : mordant dyes or indigos. Plant extracts dyeing (mordant dyes) : Natural dyeing is achieved in two steps (e.g. two baths) : 1- a mordenting step (preparation of fibres); The mordent bath is a preliminary treatment with a metallic salt that will allow a good fixation of the natural dye on the fibre. If you´re just starting to experiment natural dyes, we recommend to start with potassium alum - the most used mordant. You will then experience other mordants and discover infinite natural shades. The water quality is important for good results. The softer it is, the better results are. We recommend to carefully read our instructions and advices for good results. Instructions for dyeing with plant extracts Click here Indigo dyeing : Indigo dyeing process is different than mordent dyeing. A preliminary reduction step (resulting in a transparent greenish solution) is necessary. The textile to be dyed is then immersed in this solution. While removing the textile from the bath, the blue colour will developp by reaction with the oxygen (oxydation step). This is always a magic time!

TEXTILE PRINTING & PAINTING Printing or painting with plant colours Dye-plant extracts and plant pigments Couleurs de Plantes® can be used with any kind of printing or painting technique : screen printing, brushes, stamps, stencils... They will allow you to create large ranges of beautiful shades for your own colours, inks and textile paints for natural fibres (silk, wool, linen, hemp, ...) and some synthetic fibres (polyamide...).
Advices and instructions for textile printing or painting Two kinds of colour fixation may be used : 1- Fixation at room temperature (with a binder that will create a surface coating) or; Fixation at room temperature - printing or painting : We did select a binder safe for environment and drying at room temperature. You may also use your own binder, medium or paint. Depending on the researched shade, we recommend to use either a dye-plant extract or a plant pigment. To formulate your inks, printing pastes ou textile paints, you´ll just have to mixx a plant colour solution (or the plant pigment) into the binder. Colours from dye-plant extracts are prepared from a solution including a dye-plant extract and a mordent that will be further incorporated into the binder or medium. Plant pigments can be directly homogenized into the binder. A ´maturation´ step may be needed in order to well develop the colour. We recommend to carefully read our instructions and advices for good results. Application of your colours can be realized by screen, brushes, stencils or stamps... Allow your fabric to dry well before washing to remove all the colour that would not be fixed. The recommended Aquatex binder will provide good wash fastnesses at 40°C (100°F ). For good wash fastnesses at 60°C , it is recommended to add the proposed fixative (use at 2-3% - product from synthetic origin however). Printing with plant colours : instructions and shade card Click here Aquatex binder : technical sheet Click here Steam fixation : Your inks and printing pastes can be produced from the same principle as above. In this case, only the dye-plant extracts can be used (in combination with mordents). This application way needs an oven or steaming cabinet. Steam for an iron may not be sufficient (except for very little surfaces). It is necessary to prepare a solution of (dye-plant extract + mordent) that will be incorporated into the binder. You may use some natural binders like guar, adraganth... A ´maturation´ step may be needed in order to well develop the colour. Application is achieved by screen, brushes, stencils or stamps... Then proceed to the following steps : allow the fabric to dry, steaming fixation, allow again to dry, then wash to remove all the colour that would not be fixed.
WASHING AND CARE OF YOUR TEXTILES Wash your natural dyed textiles at low temperature (maximum 40°C). Avoid washing powders (they contain bleaching agents that will quickly fade your colours) and bleach. Dry your textile away from direct sun.
