-fiber
-yarn
-fabric
-hand
-denier

yarn:

can be created from many natural sources (animal hair or fur, insect cocoons as with silk worm cocoons),as well as semisynthetic methods that use naturally-occurring polymers, and synthetic methods that use polymer-based materials, and even minerals such as metals to make foils and wires

Fiber

hair-like materials (they look like threads) that form the building blocks from which yarn and fabric are made.

Polyester is a synthetic fiber derived from coal, air, water, and petroleum. Developed in a 20th-century laboratory, polyester fibers are formed from a chemical reaction between an acid and alcohol

a generic designation for a family of synthetic polymers, more specifically aliphatic or semi-aromatic polyamaides . They can be melt processed into fibres, films or shapes

acrylic

are synthetic fibers made from a polymer  with an average molecular weight of ~100,000, about 1900 monomer units. To be called acrylic in the U.S, the polymer must contain at least 85% acrylonitrile monomer.

Rayon

a manufactured regenerated cellulose fiber. It is made from purified cellulose, primarily from wood pulp, which is chemically converted into a soluble compound

Acetate

Acetate is derived from cellulose by reacting purified cellulose from wood pulp with acetic acid and acetic anhydride in the presence of sulfuric acid.

Spandex

Spandex is a synthetic polymer. Chemically, it is made up of a long-chain polyglycol combined with a short diisocyanate, and contains at least 85% polyurethane.
