Procion MX dyes are the best fabric dyes for cotton, viscose and other cellulose fibre
Jacquard Procion MX dyes are prepared colour mixes which save time and ensure colour consistency when dyeing. This is a fibre reactive dye; when the colour is fixed, it forms a permanent bond with the fabric; the dye molecule combines with the cellulose or protein molecule to become one molecule. Procion MX fabric dyes are best used for material, fibre and yarn made from cotton, bamboo, flax/linen, tencel and viscose.
Mix these concentrated dye powders with cold tap water to produce the best and most permanent colour on cellulose fabrics including cotton, linen (flax), bamboo, rayon and viscose. Procion MX dye is fixed with soda ash to make it wash fast. The soda ash is added directly to the dye bath for submersion dyeing. To prepare fabric for techniques such as Batik, Shibori or Tie Dye, the fabric is soaked in a solution of soda ash, and then dried, before commencing work.
Jacquard Procion MX Dyes can also be used for silk although the soda ash can dull the lustre of the fabric. It is recommended that Acid dyes are used for these fabrics. If using Procion MX dyes to dye silk, wool and other protein based fibres, substitute soda ash for an acidic dye bath.
Typically, one 18g pot will dye approximately 500g of dry fabric. Increase the dye to weight to achieve brighter, stronger colours or reduce the amount of dye to achieve paler, pastel colours.
Colours marked with an asterisk are Pure / Standardised colours
