The invention of ropes is considered to be one of the earliest and most significant creations of man. The first evidence of use of rope in Egypt is dated at sometime around 4000 B.C. The Egyptians used rope to shift gigantic stones essential to build the pyramids. The Chinese started using rope made from hemp around 3000 B.C.

Ropes are made by both braiding and twisting various fibrous and tough materials collectively to increase their strength. It is assumed that initial ropes were naturally growing lengths of plant fiber or vines. In the early times, ropes were made of varied materials including grass, leather, hair, and reeds.

A popular type is the twisted or laid rope, which is a combination of a number of fibers twisted as one to make them sturdier. Another type is made of three strands, known as plain rope. Four strand ropes are called shroud-laid rope. Numerous lengths of rope may be twisted together to form a cable-laid rope. Braided ropes are of three main types. These include a solid braid, a diamond braid with no core and a diamond braid with a core.

Ordinary rope materials include cotton, linen and silk. Other choices include hemp, manila, jute and sisal. These fibers are mostly plant derivatives, which tend to be in demand for their potency and elasticity. These ropes also have the quality of drying quickly if exposed to water. Silk ropes were a popular choice in the past as they are lightweight. However, as they are fragile, they are not commonly used today.

In today’s world, ropes are mostly made of synthetic materials. These are commonly known as braided ropes. Popular rope materials are nylon and polyester. These artificial fibers are almost always lighter than their natural counterparts. They are usually produced with the help of modern techniques rather than being handmade. These factors have attributed to the production ropes, which are easy to twist and twirl in comparison to conventional ropes. At times modern ropes are deliberately kept rigid, to guarantee little or no stretching during use as per an individuals need.
