Silk, Cotton, Flax & Wool
Natural fibers are fibers made from plants and animals. The pictures above show silk, cotton, wool & flax.
The first photo shows silk, a fiber that is from the cocoon spun from a silkworm. Silk is primarily produced in Asia, Thailand, China, India & Madagascar. It's expensive and it's the strongest of natural fibers. To properly care for silk you have to dry clean or hand wash and press with warm iron. Common uses for silk would be wedding gowns, men's ties & lingerie.
Cotton is the second photo. It is the soft, white, downy fiber connected to the seed of a cotton plant. Even though it is not the strongest of natural fibers, it is the most widely used natural fiber. It's absorbent, winkles easily and shrinks in hot water. Cotton is most used in underwear, socks, towels and shirts. To properly care for cotton you must machine wash it and press with hot iron.
Flax would be the next photo shown. The flax plants stem is where the fiber comes from. Eastern Europe is where it's mostly harvested. Proper care for flax would be to dry clean or hand wash it, and iron while it's damp. Common uses are pants, blazers, table clothes & upholstery.
The last photo of my little slide is wool. Wool is the fiber that is found in the fleece of sheep. It's soft, flame retardant and it's affected by moths. The proper care for this fiber would be to hand wash in cool water and do not place it in the drier. Most common uses for wool are sweaters, coats, rugs, and blankets.
