Plant Fibers • Seed Fibers – come from the seed of a plant • Cotton - from seed hairs, looks like a flattened, twisted ribbon. A cotton fiber
Plant Fibers • Stem Fibers – come from the stem of a plant. • Grow as bundles. • Common examples include: jute, flax & hemp (seen at right).
Natural Fibers • Mineral Fibers – neither proteins nor cellulose. • Fiberglass – a fiber form of glass. • Asbestos – naturally occurring mineral. Asbestos as seen with a scanning electron microscope.
