Fading with washing

  1. Use one synthetically and one naturally dyed square of fabric.

  2. Use the template to cut a strip from each sample.

  3. Make a record sheet to stick the two samples on and to stick more samples on after washing. Allow a space for sticking a piece of undyed fabric.

  4. Think about how you will wash the fabric. What will you keep the same each time?

  5. List the things you will use for your washing test:


  6. Now wash the samples, adding a small piece of undyed fabric to each wash. What do you think will happen to the undyed fabric?

  7. After each wash, cut another strip from each sample and stick them onto your record sheet.

  8. Stick the sample that was undyed on the record sheet too.

  9. Write about your results on your record sheet (think about things like what the results tell you about each dye, how washing affects each fabric type, and what happened to the undyed fabric).
