“…) arrangement results in a lower utilization rate for the slot. The latest book by Kyosev [20] provides a carrier motion that is emulated by combining track-and horn gear-based modeling methods, and the application of this method has been detailed in [21][22][23]. The commercial software TexMind can check the braiding carrier configurations; however, this approach is carried out under the assumption that the carrier configuration is working, and the aim of this paper is to obtain the configuration (arrangement) of the carrier in the tracks using a mathematical model, in order to avoid the collision problem.…”

This paper describes the splicing of an 8 × 8 484 cross-break track, based on the carrier arrangement characteristics (CAC) method for track splicing technology. The arrangement period of the carrier (T) in the track is obtained in order to discern which slot has a carrier in a period and which one does not. Six basic types of track unit are deconstructed, and a mathematical model is established to determine the possible state of the carrier in each slot of the track unit. Finally, the specific pattern of the carrier arrangement in the 484 cross-break track unit is obtained and verified using a three-dimensional (3D) rotary braiding machine with a square track disc. This provides a reference for solving the carrier arrangement of a 3D square rotary braiding machine.

“…For the development of the circuit, each yarn in the structure has to be analyzed and its contact points with the other yarns have to be identified. The geometry of the yarn in the current case is created using the geometrical models, integrated within the TexMind Suite packages for braiding, warp and weft knitting, weaving and sewing stitches [3,4,5,6,7]. For each type of structure is developed a separated geometry generator (Fig.…”

This paper presents the main steps, which has to be performed for automated generation of electric circuits of textile structures for wearables. The generated 3D geometry of the textile structures is analyzed and the yarns are replaced by wires or resistances. Examples of testing the algorithm with woven and knitted structure and sewing stitch are presented. The generated circuit can be imported in specialized software and used for electric simulations.

“…By establishing a geometric model, and thereafter solving it using a FEA software, more accurate rope mechanical parameters could be obtained. Therefore, a professional software, such as Texmind Braider, which can be applied in braided structure modeling, is required 17,18 ; otherwise, the task would be very cumbersome. In this light, the purpose of this study is to establish a simplified model, and from it, directly obtain approximate mechanical properties that can be useful in preliminary design processes.…”

Owing to the good mechanical properties of braided structures, regular braided ropes are increasingly being used in various fields, including marine exploration, aloft work, recreation activities, and oil prospecting. However, under certain severe conditions, they could break, a situation that is absolutely undesired. Thus, predicting their stress distribution and strain-force characteristics when they are subjected to different tensile loads is a pre-requisite for their application. Therefore, in this study, a mathematical model for ropes with regular braided structures is developed, and based on the model, this study reveals that uneven stress distributions in the different strands of regular braided ropes generate different stress distributions and strain-force characteristics in each of the strands. Additionally, the uneven stress distributions in the different strands also induce mechanical failure more readily. Finally, to ensure the reliability of braided ropes in different applications, different strand parameters are compared.
