Hair and Fiber Structure

Natural Fiber

• Cotton

• Nylon

• Polyester

• Acrylic

Hair Follicle

• A structure that produces sweat

• The “pocket” in the skin where hair grows. It’s under the skin surface.

• A type of skin cell that protects against UV rays

• The outer layer of skin that provides a barrier

Yarn

• A type of fabric made from threads.

• Fibers twisted together to form long strands.

• A tool used for knitting.

• A method of weaving fabrics.

Cortex

• The outermost layer of hair, providing protection.

• The middle layer of hair, gives strength and contains pigment.

• The innermost layer of hair, responsible for moisture retention.

• The layer of hair that determines its texture.

Mineral Fiber

• Fibers made from living natural materials.

• Fibers made from synthetic materials.

• Fibers made from non-living natural materials. Example: asbestos.

• Fibers made from animal products.

Natural Fiber

• Fibers that come from synthetic materials.

• Fibers that come from plants, animals, or minerals.

• Fibers that are exclusively made from plastics.

• Fibers that are only found in the ocean.

Medulla Patterns

• Continuous (one full line)

• Interrupted (line with gaps)

• Solid (completely filled)

• Curved (smooth line)

Secondary Transfer

• Fibers move via an intermediate object. Example: sweater → chair → another person.

• Fibers are transferred directly from one person to another.

• Fibers are destroyed in the process of transfer.

• Fibers are only transferred through water.

Cuticle

• The outer layer of a hair strand that protects it.

• The inner layer of a hair strand that provides strength.

• The part of the hair that determines its color.

• The root of the hair that anchors it to the scalp.

Regenerated Fiber

• Made from synthetic materials only.

• Made from natural raw materials but processed chemically. Example: rayon (from wood pulp).

• Made from 100% recycled materials.

• Made from animal fibers only.
