Petroleum and Fiber (Chemistry)

Cellulose - Cellulose is a complex carbohydrate that forms the main structural component of plant cell walls. Therefore, it is the fundamental base of most vegetable fibers like cotton, linen, and jute.

Silk - Silk, a natural protein fiber produced by certain insect larvae, is considered the strongest natural fiber due to its high tensile strength compared to its weight.

Wood pulp - Rayon is a regenerated cellulose fiber, meaning it is derived from natural cellulose sources, primarily wood pulp, which is chemically processed to create the fiber.

Teflon - Teflon, also known as polytetrafluoroethylene (PTFE), is a synthetic fluoropolymer that has excellent non-stick properties and is commonly used as a coating for cooking utensils.

Bakelite is a plastic (polymer). It was discovered in the year 1907 by the Belgian-American chemist Leo Beechland. Bakelite is a chemical mixture of phenol and formaldehyde. It is used in insulating parts of electrical equipment.

Polymer - Bakelite is a synthetic polymer, specifically a thermosetting plastic. It is formed by the polymerization reaction of phenol and formaldehyde.

Polyvinyl chloride (PVC) is known for its combination of lightweight and high strength, making it a suitable material for various applications. It's commonly used in pipes, plumbing, building materials, and even some clothing items. 

Nylon thread is a kind of polyamide polymer. It is obtained from diamine and dicarboxylic acid. Due to the variety of diamine and dicarboxylic acids found, many polyamide substances are added to obtain nylon fibers.

Nylon - Nylon is a synthetic polyamide fiber, making it a man-made fiber. Cotton and wool are natural plant and animal fibers, respectively, and silk is a natural protein fiber produced by silkworms.

Nylon 66 is used to make hair brushes. Nylon 66 is used when high mechanical strength, hardness, and good stability under heat, and chemical resistance is required. It is used for tying the edges of garments and carpets and the molded part in the middle.
