Final answer:
Kevlar and Nylon can both form hydrogen bonds, contributing to their unique properties with Kevlar’s strength suitable for bulletproof vests and Nylon’s durability ideal for stockings. Dacron, a polyester type, is used in wrinkle-free clothing blends.
Step-by-step explanation:
The properties of fabrics made from the polymers Dacron, Nylon, and Kevlar are indeed distinct due to their molecular structures and the types of bonds between polymer chains. Kevlar, known for its high tensile strength-to-weight ratio, features hydrogen bonds between polymer chains, as evidenced from diagrams showing dotted lines, which represent these bonds. These hydrogen bonds contribute significantly to Kevlar's strength and rigidity, making it suitable for use in bulletproof vests and other high-strength applications. On the other hand, Nylon is characterized by its amide bonds, also known in biological polymers as peptide bonds, which make it similar to some proteins. Nylon is durable and elastic, making it ideal for products like durable stockings and other fabrics. Meanwhile, Dacron, a type of polyester, consists of ester bonds in its polymer chains and is blended with cotton to create wrinkle-free clothing.
