| Abstract: | This paper briefly describes the development of spunlaid technology and analyzes the characteristics of various drawing systems. It demonstrates the importance of drawing system on the spunlaid technology. The article points out that the calculation of the gas current field of drawing system is necessary and urgent. According to the gas-kinetic theory and liquid-kinetic principle combined with automatic control, it calculates the various gas current parameters with different kinds of friction on the drawing system of NWT from Italy, and compares that with the trial data, then know the easy methods of measurement for drawing system performance and provides the theory warrant for establishing the mathematics models between various parameters and gas current parameters of drawing system and optimizes the design for drawing system. |
