Types of rope

In a simple beginning, it can be said that a thin strand of rope or lasso or twine, a long strand of intertwined fibers is called rope, currently available in different types of rope. In general, strings have different structures and structures, which are produced in two twisted ways. Normally, the structure of the strings depends on their manufacturing method. Wool, hair, nylon, polypropylene, hemp, linen, steel, etc. are among the materials used to make the rope. Note that if the rope is made of hemp, it will show more strength when placed in the water. A variety of knots are used to tie the ropes together.

Types of rope

natural rope

This type of product is produced with environmentally friendly products and no chemicals are used during production. In the production of this rope, materials such as hemp, sisal, cotton or other natural fibers are used. Sometimes they produce this type of high strength product from the combination of different natural materials. Although the natural type is strong, it is not as durable as the synthetic type and is easily damaged by water, mold and UV rays. Unlike the synthetic type, the natural type is not damaged by exposure to high heat and only burns when exposed to flames.

Unfortunately, the natural type shrinks when wet and is very difficult to work with once dried. This type is ideal if you need to pack objects or a rope that has excellent adhesion. Natural ropes are biodegradable and can be naturally decomposed. It is not as difficult to dispose of as its synthetic counterpart.

Synthetic rope

Synthetic or plastic rope is made from materials such as nylon, polyester, and polypropylene, although there are other materials that can be used to make these ropes. Their durability is much higher than natural ropes and this is one of the reasons for their popularity. Their lifespan is often 30% longer than natural ropes and they are much stronger when wet and aged. These products will be less damaged by mold, water and UV rays. In general, high heat can melt all types of rope and reduce their level of stability.

Also, synthetic ropes shrink less when wet, but exposure to enough heat causes the rope to melt, which can reduce its strength. They are stronger and have more elasticity, which makes synthetic ropes useful for towing and lifting, but it is difficult to prevent knots from slipping in the synthetic type. These products are often non-biodegradable and harmful to the environment.

Rope construction

The ropes are divided into two categories according to the type of construction:

Nuclear rope

This type of rope is very useful in climbing. Climbing ropes have a central structure that comprises about 75% of the core and have a high strength. This type of rope consists of two parts:
Core: usually its material is perlon. The elasticity characteristic of this type of rope is due to its core. The core threads of the rope are placed side by side with two methods of twisting and weaving.
Shell: made of polyamide - protection from external factors

Intertwined ropes

This type of rope can be produced with natural and synthetic fibers and has a lower resistance.

Marine peaks

These types of ropes are divided into different categories based on the materials used, their structure and strength, and these things will distinguish them from each other. The types of marine ropes have different names.

sisal rope

The leaves of the dagger flower plant, which is a cactus species, are used as the material in the sisal rope. This plant grows in Kenya, Madagascar, Indonesia, Haiti, Tanzania and Brazil. The fibers obtained from this plant are thin like hair and amber in color. Sisal rope is as strong and durable as Manila rope. In any case, as soon as signs of deterioration and wear are observed, it must be repaired.

Manila rope

In the Manila rope, the fibers obtained from the banana leaf are used, which is similar to the banana tree. The color of the fibers obtained from this plant is golden brown and the plant grows in the Philippines and is then exported to different parts of the world through the port of Manila. The cleaner the fibers obtained from this plant, the higher the quality of the rope. One of the characteristics of this rope is its strength and resistance to the salinity of sea water and wear stability. This rope is used for light transport at sea, boat work and moving heavy equipment.

wool rope

The wool or goat rope is a product of our country, which is very practical due to its similarity to the hemp rope. The fibers used to make the wool rope consist of goat and sheep hair, which after the spinning process is transformed into threads and produced.

Hemp rope

Hemp rope is an example of ropes that are inserted into natural fibers made of hemp and are produced in the form of twisted and very thick threads. Jute ropes have high resistance to salt sea water. These ropes are woven in large spinning workshops in various countries. Brazil is the producer and exporter of this type of rope in the world. One of the applications of this product is in navigation and navigation, which is very high due to its high wear stability caused by contact with water. Such cords are also used for weaving carpets, moving lumber, or connecting them together. The color of the fibers is one of the factors that influence the quality of hemp ropes.

twisted rope

This rope is very good but if you want to twist it easily. Twisted is a very common type that is usually used for dock lines and tow lines. These cords are formed by tying the strands together and making sure they are in the same direction. The fibers within all three strands must rotate in opposite directions for the string to adhere. This type is generally inexpensive and has much higher elongation than braided rope, which can be good in some applications. Unfortunately, it's less flexible and less stiff than braided rope, and if you're not careful when using it, it can get tangled.

last word

The use of the rope dates back thousands of years when it was used to bundle, connect, climb, carry and lift. As you know, ropes fall into two categories: man-made and natural. Each of them has different advantages and disadvantages. Synthetic ropes are often more durable and the structure and texture of these ropes and their high tension have made them useful for lifting and lifting objects, but slipping and loosening of knots somehow limit working with them and are easily absorbed in nature.
