The USB microscope will be attached to the Mac computer in our lab. Write a paragraph or two that describes how your yarn was made and justifies your choice of materials.
Measure and report the following properties (if they are relevant for your yarn):
- diameter (micrometers)
- total length of yarn (meters or yards)
- ply
- fiber length (millimeters)
- twist direction
- twist (turns per inch)
- conductivity (ohms per centimeter or ohms per inch)
Bonus points for measuring any of the following properties and explaining how you did so:
- denier or tex
- yarn size
- tenacity
- elongation
- elastic recovery
- absorbency
