What is scoouring!

Scouring is the process of removing natural impurities (waxes, fats, pectins, oils) and added impurities (sizes, lubricants, dirt) from textile materials—especially cotton and other cellulosic fibers. The goal is to make the fabric clean, hydrophilic, and uniformly absorbent.

Types of Scouring Processes Alkali Scouring Uses sodium hydroxide and auxiliaries. ✔ Most common for cotton ✔ Highly effective impurity removal ✔ Produces excellent absorbency

What is a mordant?

A mordant is an ingredient that helps the dye bind to the fibre. Mordanting, along with ‘scouring’, is a fundamental step in the natural dye process. It sets you up for successful colour results. Incorporating mordanting into your natural dye practice can be the difference between colours that delight and colours that disappoint, fade or wash out.

How-to use footnotes for fabrication files

Fabrication files are a necessary element for evaluation. You can add the fabrication files at the bottom of the page and link them as a footnote. This was your work stays organised and files will be all together at the bottom of the page. Footnotes are created using 1 (without spaces, as shown in Step 1 & 2, and referenced as you see at the bottom of this page) You can reference the fabrication files to multiple places on your page.

### 5.1 Documenting experiments in a table for comparison

  • example from the documentation of Petra Garaiová FabTextiles Barcelona 2021-22
Material name Fabric composition Dye treatment Color Hue Color Intensity Stretchability Observations
M1 Plant fibers - muselin Normal Low Low Low Cool or warm
W1 Animal fibers - wool Normal Low High Low Cool or warm
  • Two ways of showcasing and comparing results with images below

On the left an image of a sample made by xxx with xxx. On the right, an image of a sample made by xxx with xxx and xxx.

6. Weekly reflection & critical thinking

  • What did I learn? What did I personally find interesting or surprised me?
  • What would I do differently? If something "failed" do I know how else to tackle it now?"
  • How does this connect to my final project or my learning trajectory?
  • What are implications and possible applications, think also from the ethical or environmental aspect, how it could connect to your practice and project?

NuEval — final step

Go to NuEval and fill in the checklist, when not complete notify your instructor.
