This article studies a weaving process for producing knotless mesh fabrics based on the principles of weaving technology and the characteristics of knotless mesh structures, focusing on three key factors: the arrangement of spindles, the combination of tracks, and the mesh structure. This process divides the weaving process without knots into three stages: net foot weaving, net knot weaving, and net foot net knot transformation. The weaving systems for each stage are designed one by one to ultimately complete the entire weaving scheme without knots　　

Firstly, in order to solve the problem of spindle interference in the process of weaving without knots, the spindle arrangement is converted into a numerical sequence, and the interference situation is converted into mathematical constraints. The solutions to various interference problems are calculated, and the selection method of spindle arrangement rules to avoid interference and the design criteria for track structures are derived. Then, based on the above criteria, research and design weaving schemes with different numbers of strands without knots. By analyzing the structure of single and double stranded knotless fabrics, the weaving rules of their internal yarns are obtained, and a rotary weaving process for this weaving method is designed. According to the non-interference theory, the weaving track forms and spindle arrangement schemes for multi strand knotless net foot weaving and net knot weaving were designed separately. By first positioning the spindle and then changing the track, the free switching between the net foot weaving process and the net knot weaving process was achieved. 　

In order to better present the fabric structure and verify the correctness of the above theory, based on the concept of feature point modeling, the position feature points of the spindle during the weaving process are extracted as initial data, and the trajectory data of the yarn is fitted and interpolated to create a digital model of the fabric and a simulation animation of the weaving process. At the same time, a program for generating knotless weaving schemes with a graphical interactive interface has been developed. Through this program, weaving schemes with different numbers of mesh legs and control data of the track changing turntable during the weaving process of each scheme can be obtained. Finally, a set of knotless weaving experimental equipment was designed and developed, and the variation law of weaving points during the weaving process was analyzed. The appropriate weaving point height and fabric traction speed were selected based on weaving angle and yarn storage capacity. The correctness and feasibility of the designed knotless weaving scheme were verified through actual production.

Jiangsu Zhongwanglan New Materials Co., Ltd. has a Zhongwanglan New Materials Research Institute. Led by senior domestic experts, providing technical support for the development and industrialization of advanced and efficient mesh free weaving equipment. Through years of technological research and development, we have broken through the conventional width of 100 mesh for twisted and knotted nets, reaching 200 mesh. Reduced the workload of mesh splicing and deformation of mesh connection, and improved the safety of long-term use of marine ranch net cages. Based on the special requirements of different occasions for mesh clothing, we have successfully solved the three strand cross knitting technology through technological innovation. These two technologies have filled the domestic gap, broken the technological blockade imposed by foreign countries on China so far, and filled the gaps in China's advanced network equipment such as high efficiency, energy conservation, marine resources, and defense. The research institute has also conducted in-depth research on the application of ultra-high molecular weight polyethylene in net cages. Ultra high molecular weight polyethylene is woven without knots, and the fracture strength of the mesh is more than twice that of other materials, while the weight can be reduced by 30%. There are also innovative resin coating materials and formulations, as well as composite protection technologies, which endow composite mesh with excellent loading fatigue performance and aging resistance and longevity.
