“…Also, different researchers provided fundamental information concerning the conveyor belt design and woven fabric structure used for the intent of conveyor belt reinforcement [6] [7]. In previous works various scholars researched in the area of factors that affect the properties of conveyor belt [8][9][10][11][12][13]. However, the effect of vulcanization process on the mechanical properties of textiles used for the reinforcement of conveyor has been left behind.…”

The use of textiles produced from high tenacity(HT) polyester yarns as a reinforcement material in the mechanical rubber goods industries, mainly in the conveyor belt, is extensively increasing due to their high tensile strength, flexibility, thermal stability, modulus of elasticity, and light weightiness. To achieve the desired property of a conveyor belt, the reinforcement components undergo various processing stages; among those stages vulcanizing the reinforcement materials under high temperatures is the crucial process that determines the physical and mechanical properties of the conveyor belt. The main aim of this work was to analyze the effect of vulcanization parameters on the physio-mechanical properties of high tenacity polyester yarns and fabrics that are utilized to reinforce a conveyor belt. An extensive experimental study was conducted on a pre-activated HT polyester yarn of different linear densities and woven fabrics produced for the purpose of conveyor belt reinforcement by subjecting the yarns and fabrics to various aging temperatures for a certain period of aging time. Following the experiments, a comprehensive study and analysis were conducted on the tensile property of the yarns and fabrics. The finding revealed that thermal aging has an immense impact on determining the tensile strength and elongation of the yarn and woven fabric, which also has a direct influence on the properties of the conveyor belt. The analysis of experimental test results of polyester yarns and woven fabrics revealed that vulcanizing textile-reinforced conveyor belt at high temperatures (220 °C) could deteriorate the tensile strength and increase the elongation at break of the yarn, fabric, or belt.

“…Several researchers have carried out various studies in order to establish optimized conveyor belt construction and processing parameters. Chou et al [8,11] used a Taguchi method to determine optimum conditions for vulcanizing textile-reinforced conveyor belts with better elongation, adhesive strength, and abrasion resistance. Amr et al [12] also investigated the effect of the number of plies of the reinforcing materials, loading direction, and speed on the tensile strength of conveyor belts reinforced with a woven fabric using the Taguchi method.…”

Textile-reinforced conveyor belts are most widely used in various industries, including in the mining, construction, and manufacturing industries, to transport materials from one place to another. The conveyor belt’s tensile strength, which primarily relies on the property of the carcass, determines the area of application of the belt. The main aim of the current work was to investigate the influence of vulcanization temperature and duration of the vulcanization process on the tensile properties of the carcass part of the conveyor belt. An extensive experiment was carried out on the tensile properties of woven fabrics that were intended to reinforce conveyor belts by aging the fabrics at the temperature of 140 °C, 160 °C, and 220 °C for six and thirty-five minutes of aging durations. Afterward, the textile-reinforced conveyor belts were produced at vulcanization temperatures of 140 °C, 160 °C, and 220 °C for six and thirty-five minutes of vulcanizing durations. The influence of the vulcanization process parameters on the tensile property of fabrics utilized for the reinforcement of the conveyor belt was analyzed. In addition, the effect of the dipping process of woven fabric in resorcinol–formaldehyde–latex on the tensile property of polyester/polyamide 66 woven fabric (EP fabric) was investigated. The investigation results revealed that the tensile strength of the carcass of the conveyor belt was significantly affected by vulcanization temperature. The conveyor belt vulcanized at 160 °C for 35 min has shown the optimum tensile strength, which is 2.22% and 89.06% higher than the samples vulcanized at 140 °C and 220 °C for 35 min, respectively. Furthermore, the tensile strength and percentage elongation at break of conveyor belts vulcanized at 220 °C were almost destroyed regardless of the vulcanization duration.

“…It is very important to have a robust measurement system explaining from the method of data measurement up to its optimization with minimum variation in the system. Most published papers discussed the test method used in some case studies [9][10][11][12][13][14][15][16][17][18][19][20][21] while others discussed the measurement concepts and theories [8,10,[22][23][24][25]. However, less research has been done to connect both aspects in a single study [9].…”

A robust measurement system in the Taguchi Method as a testing method should be explained from the beginning of an experimental design until the application of the optimum condition. Measurement has always been described either by discussing the measurement concepts theoretically or demonstrating a case study on how the data measurement is being done practically. The distance between theory and practical case study that connects the test method used for measurement is always missing. In this paper, a case of T-peel test on strength measurement is used to reflect the robust measurement system, which includes the theory of experimental design together with methods to achieve the optimum condition. Seven control factors, two noise factors with one signal factor are used with orthogonal array L18. Not only the experiment results, but methodology on choosing the control, noise, and signal factors are described intensively. Therefore, the aims are to provide the procedure on evaluating optimum conditions, to analyze variability and optimization of T-peel test when measuring the strength, and to establish a mainstream flow to achieve high-quality experimental design for a robust measurement system. As a result, a robust measurement system that includes variation elimination is developed, which consists of four elements—F (function), N (noise), C (Control), and O (Optimization). The elements of the F-N-C-O system are connected to one another by the Plan-Do-Study-Act; P-D-S-A cycle. The results affect the existing measurement system by enlightening the black box of parameter design behind optimization results in Taguchi Method. Thus, the measurement is more convergent and obtain higher degree of confidence in parameter design.
