Title:
Looking at fibres
Aim:
To investigate natural and synthetic fibres under the microscope. Hypothesis:
I predict that natural fibres will appear rough and taper under the microscope and synthetic fibres will appear smooth. Method:
Refer to text book 1, 2-2 fibres and fabrics.
Results:
Fabric sample to touch

Unknown 3.

Unknown 4.
Pink, plastic

Discussion:
The results collected in my first table show that all fibres were soft to touch. These fibres also had differences in elasticity and some had a different texture on the underside of the fabric. The results collected in my second table show what different fibres appear like under the microscope. A vast majority of these fibres appeared white under the microscope. The unknown fibres under the microscope have similarities to those of Silk, Rayon and string. Conclusion:

In conclusion different fibres appear different in colour and texture under the microscope.
