This resource is aimed at students taking OCR Secondary Science A5 who are taking the colorant module.
The lesson in this course contains

- Teacher and student resources
- An Introduction to the Chemistry of Organic Colorants
- A worksheet explaining how to use the Triple Dye Kit
- the structure and names of the dyes used in the Triple Dye Kit
The SDC has worked closely with experts from industry and education to produce the ‘Different dyes for different fibres’ educational resource kit.
This practical science and technology kit provides everything needed (apart from a kettle of hot water) for an easy demonstration of the dyeing process that highlights the difference between fibres. It amazes pupils with an excellent introduction to some of the ways in which our clothes are coloured and also introduces pupils to the existence of a range of fibres.
The demonstration provides dramatic results in a few simple steps. Three coloured dye solutions (red, yellow and blue) are supplied. Mixed together they form a murky brown solution and the magic occurs when the SDC multi fibre strip is added.
The multi fibre strip is a specially woven fabric that contains six different fibre types. The three dyes are fixed to different fibres meaning the fibre that emerges out of the murky dye bath has yellow, red, blue and white stripes!
