Fibers

Natural fibers can be harvested from:

• Plants and animals
• Plants only
• Animals only
• Plants, animals, and minerals

What characteristic of cotton make it a great source of fiber for clothing?

• Stain resistant
• Fibers are easily woven and dyed
• Fibers are extremely long

Mineral fibers such as asbestos are very durable. They’re used in all of the following except:

• Rope
• Shingles
• Floor tiles
• Brake linings

All of the following are characteristics of synthetic fibers except:

• They are formed by combining monomer compounds into polymer molecules
• They’re manufactured
• Used in production of carpet fibers
• Produced by plants, animals, or other organisms

A characteristic of natural fibers is that they

• Are affected by microscopic organisms
• Will break down when exposed to bright light
• Melt at a lower temperature than synthetic fibers
• Are stronger than synthetic fibers

What is a fiber?

• Small, repeating molecules that link to form polymers
• Smallest indivisible unit of a textile, must be at least 100 times longer than it is wide
• Flexible, flat material made of yarn or thread
• Substance composed of repeating monomers

The type of weave pattern in a fabric affects all of the following except:

• Shiny appearance
• Stretch of fabric
• Solubility in water
• Strength of the fabric
