“…An alternative, less accurate modelling approach generates textile structure geometries relatively quickly and is based on parametrical models, thus representing the structure topology (5). In this case, a generalized model of the yarn axis is obtained from the carrier motion process (6). There are several numerical simulations of ropes employing FEM (7) in addition to numerous analytical models (8,9).…”

Braided structures are widely used in numerous contexts including everyday practice. In most cases, rope ends are knotted to form various types of loops or tie them to rigid body parts; however, knots take up space that may not be available in some application scenarios, thus making them unsuitable for certain purposes. Hence, this paper introduces first development steps of a method for the numerical simulation of rope ends connected by sewing stitches.

“…Several researchers try to produce textiles-like geometries, where interlaced or interloped solid elements build 3D printed knitted or woven structures. For example braided structures for ropes or medical braids can be generated using parametric algorithms reported in [27][28][29] and implemented in professional CAD like [30] from where the generated 3D geometries of braided ropes, braided medical stents, warp and weft knitted pattern, woven structures can be exported to STL (stereolithography) format and send to the 3D printer directly.…”

The application of additive manufacturing, well known as 3D printing, in textile industry is not more totally new. It allows is giving significant increase of the product variety, production stages reduction, widens the application areas of textiles, customization of design and properties of products according to the type of applications requirement. This paper presents a review of the current state-of-the-art, related to complete process of additive manufacturing. Beginning with the design tools, the classical machinery building computer-aided design (CAD) software, the novel non-uniform rational B-spline (NURBS) based software and parametric created models are reported. Short overview of the materials demonstrates that in this area few thermoplastic materials become standards and currently a lot of research for the application of new materials is going. Three types of 3D printing, depending on the relation to textiles, are identified and reported from the literature—3D printing on textiles, 3D printing of flexible structures and 3D printing with flexible materials. Several applications with all these methods are reported and finally the main advantages and disadvantages of the 3D printing in relation to textile industry are given.

“…The test ropes were a traditional double braided structure with the diameter of 10 AE 0.01 mm. The sheath was produced with arrangement 1 full 1 empty with floating length of one 27 32 braided structure with a thickness of 1 mm, and the braiding angle was 25 . The rope core is also a braided structure with arrangement 2 full 2 empty with floating length of one and eight strands.…”

Thermal damage is an important failure mechanism that affects the bending failure of fiber ropes. This is relevant because synthetic fibers often have a relatively low melting point and low thermal conductivity. In cyclic bending over sheave (CBOS), the heat generated by friction and deformation is not conducted rapidly to the external environment, and the temperature of the rope core increases quickly. This higher temperature greatly reduces the mechanical properties of the fiber, thus accelerating the final rope failure. In this paper, evidence of thermal damage in the bending process of a braided synthetic fiber rope is given. The test conditions inducing thermal damage are discussed, including stress level, bending frequency and diameter ratio. The reasons for the heat generation and the dynamic process of heat accumulation inside the rope during CBOS are also discussed. This study aims to provide theoretical and experimental guidance for the design and use of fiber rope.
