5. WHAT IS NYLON Nylon is a synthetic fabric made from petroleum products. It was developed in the 1930s as an alternative to silk, although it quickly became unavailable to civilian consumers, because it was used extensively during World War II.

6. Like many synthetics, this material was developed by Wallace Carothers at the DuPont Chemical company, which continues to manufacture it today. Nylon is valued for its light weight, incredible tensile strength, durability, and resistance to damage. It also takes dye easily, making the fabric available in a wide array of colours for consumers.

7. Today, nylon is among the many polymer products in common daily use throughout the world. It is the second most used fibre in the United States, since it is so versatile and relatively easy to make. Like most petroleum products, it has a very slow decay rate, which unfortunately results in the accumulation of unwanted products in landfills around the world

10. Comparison between synthetic and natural clothes On the basis of material (synthetic) Synthetic rope is constructed of materials such as nylon polyester and polypropylene. On the basis of material (natural) Natural fiber ropes are constructed from cotton, sisal, and hemp fibers.

11. On the basis of durability (synthetic) Synthetic rope is light weight. It has a 20-percent stronger tensile strength. Synthetic rope does not shrink when wet. It will melt though when exposed to heat. On the basis of durability (natural) Natural fiber rope are heavy weight. It has weaker tensile strength. Natural fiber rope shrinks when wet. Natural fiber ropes are damaged by direct contact with fire.

12. On the basis of environmental effects (synthetic) Synthetic rope is created using plastics with dangerous chemical byproducts. On the basis of environmental effects (natural) natural fiber ropes are woven from jute, sisal, and, hemp--all renewable and biodegradable resources with no chemical byproduct.
