Wonky Weaver® Java Plum Natural Plant Dye Powder is derived from the botanical Syzygium cumini otherwise known as Black Plum or Java Plum.,.  It is known that the dye shows a natural antimicrobial effect against some bacteria so it has been explored for use in the development of antimicrobial fabrics.  Java Plum yields a browny, natural beige colour, colour depending on what mordants are applied.
 
It is always recommended to first wash and scour the fabric prior to dyeing, and when using cotton, you need to pre-mordant in a tannin bath before mordanting with ALUM, or use Aluminium acetate for better dyeing results.  Also for animal fibres such as wool and silk, also scour, and mordant before dyeing.  You should expect shades of greys, purples and violet depending on the application. 
 
It should be used at a range of between 10-20% weight of fibre (WOF) depending on intensity of the desired colour.
 
Wonky Weaver® Natural Plant Dyes and Extracts are derived from botanical sources, and are both sustainable and ethically produced.  We carefully source our dyes from suppliers we trust to uphold the highest of standards in quality.   
 
Using plant dyes is very enjoyable and satisfying but does require some degree of experimentation to get the desired coloration of your fibres, yarns and fabrics.  Results also depend on the type, weight and make-up of the fibre, and water quality, temperature and length of time in the dye bath amongst many other factors.  The type of mordants, dye assists and modifiers will also affect the resultant colour of your dyed materials.
 
The Black Plum Dye Powder is supplied in 50g resealable pouches which should be sufficient to dye up to 200g-500g of fibre depending on intensity of desired colour.
 
Please store your dyes out of reach of children, out of sunlight and under dry conditions.
