The aim of this study was to optimize the tensile strength of nylon for badminton string by investigating the effects of different testing conditions (temperature, relative humidity, and tensile rate). The results showed that increasing the processing temperature and humidity had a negative impact on the tensile strength, while increasing the tensile rate had a positive effect. A mathematical model was established using a response surface methodology to predict the tensile strength, and the optimal conditions were validated. Analysis of variance was employed to determine the significant effect of each term on the final response. The optimum processing temperature was found to be 2.9°C with a relative humidity of 0% and a tensile rate of 60 mm/min.
Nylon is a thermoplastic engineering material widely used in several applications. But to increase the application of nylon in sports, the focus of this work was to optimize the tensile strength of nylon for badminton string. In particular, the testing conditions (temperature, relative humidity and tensile rate) were investigated. The results obtained showed that increasing the processing temperature and humidity both had a negative effect on tensile strength, while increasing the tensile rate had a positive effect. Then, a mathematical model to predict the tensile strength was established by using a response surface methodology and the optimal conditions were verified to validate the parameters. Furthermore, an analysis of variance was used to determine the significant effect of each term on the final response. Based on the results obtained, it was found that the optimum processing temperature is 2.9 degrees C with a relative humidity of 0 % when the tensile rate is 60 mm/min.
