Optimization of technological parameters in ultrasonic welding of the polypropylene fabric using Taguchi and FCCCD methods

Ultrasonic welding is a method that has been applied for nonwoven fabrics, with many advantages such as fast speed, high reliability, easy automation and especially less pollution to the environment. This paper studies optimization of technological parameters in process time, pressure, weld shape on breaking strength ultrasonic Polypropylene (PP) nonwovens. To evaluate influence level find reasonable domain paper, Taguchi used combination face-centered central composite design (FCCCD) response surface method. The research results have determined regression equations calculate each well optimal main parameters, ensuring weld. There are different degrees (shape zone, time pressure) welds. Among them, t 45.31 %, Pattern 2 rate 30.03 pressure 24.66 %. Carrying out verification test parameters: t=1.6 s, p=3.1 kgf/cm2, two patterns ( 3), result was achieved. difference 1.19 % between equation actual experimental results, while figure 3 0.77 From these it possible select appropriate equipment when processing products from fabrics ensure highest quality productivity
