Polymers: large molecule made of connecting small molecules together. Almost all fibers are polymers made of organic materials: all contain carbon, combine with each other, chainlike arrangement. Iii: hundreds/thousands of atoms bonded together in subunits, macromolecule. Polymerization: formation of polymers, joining of monomers. Definition: smallest unit that can be separated from a fabric. Properties: chemical, physical, mechanical: fineness, flexibility, strength, durability, absorbent, etc. Possesses suitable characteristics for being processed into a fabric. Yarns: assembly of fibers twisted or laid together so as to form a continuous strand that can be made into a textile fabric. Different types of yarn with same fiber can look different. Greige goods (gray goods or grey goods: unfinished fabrics, rare. Iii: buy greige goods and convert into finished fabrics or apparel.
