Two specific types include Nylon 6 and Nylon 6,6.
Nylon was the world’s first Synthetic Textile Polymer and it is a fiber.
Nylon was developed as a synthetic substitute for silk.
Dr. Wallace Carothers found nylon while he was experimenting at the DuPont plant.
Later the DuPont company built huge nylon plant in Delaware.
Cross- Linkage does not occur in the process of forming Nylon.
Nylon is renewable and recyclable because it can be broken apart to form new nylon or a new product.
Nylon is recycled frequently to make carpets. Only some kinds of nylon are biodegradable (nylon 6,6 IS biodegradable).
Linking of Monomers:
Nylon is made from monomers adipoyl chloride and hexamethylene diamine.
Nylon 6,6 Linking of Monomers: Dehydration
COOH acid group on each end and react with other molecules which are partially made of amine (NH2).
Dehydration synthesis because there is one H from COOH and with one H from Amine (the other one stays), which forms H2O, so it links by form of dehydration.
Nylon 6 Linking of Monomers: Dehydration
Amine is placed one end, acid is located on the other and is polymerized to form a chain.
In both types, the linking begins with an aqueous solution of monomers and then goes through polymerization, spinning, drawing or draw-texturing.
Explanation of Picture:
The Carbon’s are the central atom.
(The green ones).
Hydrogen is represented as white.
The oxygen is red and the nitrogen is blue.
Hydrogen is linked to the amine but then separates and OH separates from the acid, then this becomes H20, water, so dehydration synthesis occurs to link the bonds together.
Characteristics of Nylon:
Resistance to fungus, oil, chemicals, insects and animals
Low in moisture absorbency
Does not burn- melts
Highly Resilient- Flexible
Uses of Nylon:
Used in carpets, clothing, luggage, car parts, tights.
Bedspreads, curtains, upholstery
Hoses, Tire cord, seat belts, parachutes, ropes, camping equipment..
