In conclusion that the ropes used in the maritime industry are generally produced by twisting or braiding production methods, which started with natural fibers 3300 years ago, continued with natural fibers such as linen in 80 AD, and thanks to the technologies developed in the process until today, various conventional or high performance (technical) yarns. Depending on the type of yarn used, yarn number, braid diameter, twist angle, braid angle, braiding geometry, braiding layer number, braiding construction, the values of various mechanical performance tests such as bending, twisting, sliding, creep, fatigue, and tensile strength and wear It changes the values of various physical and chemical performance tests such as corrosion, chemical, and UV resistance. The highest various mechanical performance values; With high performance (technical) yarns, high yarn counts (dtex), high twist amount, high filament count, optimum (close to short fiber length such as 6 mm) filament length, high number of braiding layers used, use of braiding construction such as Three-strand, low braiding angle (- 45°), low drafting speed, 3D braiding geometry will enable the observation of various mechanical performance values at the maximum level in various experimental studies to be carried out in this field in the future.

Historical background and world marketing for rope structures The oldest rope was discovered 3300 years ago during excavations in Egypt. At that time, depictions of people climbing mountains, trees, and rocks with rope-like structures were found in the drawings in the caves. [one]. In the 500 BC, boats also pulled and fixed with ropes were found. [1,6]. The sails are plain woven canvas fabrics, presumably from flax yarn. Lots of designs of ancient vessels, which are made of natural fibers have been found in Ecuador and Peru abosince ut 500 A.D. [10]. In Thor, Heyerdahl's (1950) classic Kon-Tiki expedition (Pacific by raft) was made by tying logs of sal balsa tightly together by knotting them with quarter-inch diameter hemp threads. Decks woven with split bamboo reeds were made. The boat part was made of braided bamboo straws, the pole part was covered with bamboo slats, and the ceiling part was covered with banana leaves. Moreover, masts and rudders were made of mangrove wood. [10].
