Polyester fibers are long-chained polymers produced from elements derived from coal, air, water, and petroleum. In general, polyester fiber is characterized as having a high degree of stretch resistance, which means that polyester ropes are not likely to stretch out of its original length too easily. A thermoplastic material composed solely of ethylene. It is normally a translucent, tough, waxy filament which is unaffected by water and by a large range of chemicals. Briefly describe them.
Polypropylene is practically non-absorbent.
PP cannot be saturated with water. PP deteriorates when exposed to direct sunlight. The ultraviolet light causes its breakdown. To overcome this, UV-stabilizers are added to our PP ropes to protect against light degradation. The safety factor is 7.
