Silk is another important protein fiber

Lets talk about wool specifically

What is bad about protein fibers?

How do protein fibers get such a high moisture regain?

How does the chemical arrangement of polymers influence the strength of a fiber?

Surface contour is an extension of fiber cross section.

Cross Section is an important predictor of properties like luster or bulk.

Diameter is another physical property of fibers we must consider.

Long fibers, called filaments, have different properties than short fibers.

We pick up with the slide that separates fibers into several categories.
