Embodiment 1
[0035] see figure 1, thermoplastic elastomer non-woven fabric material and processing technology, including a processing equipment rack, a melting extruder 1 is fixedly connected to the processing equipment rack, and the melting extruder 1 includes a heating sheet, a temperature sensing head and a control board, and the control board can The melting temperature in the melt extruder 1 is controlled at 200 degrees Celsius, and the non-Newtonian exponent n of the polyurethane melt shows a peak value as the temperature rises. When the temperature rises to 200 degrees Celsius, n reaches a maximum value of 0.85, which is close to the rheology of a Newtonian fluid The behavior is not easy to make the viscosity fluctuate too much, and it is not easy to affect the quality of the non-woven fabric 10. The extrusion end of the melt extruder 1 is fixedly connected to the metering pump 2, and the output end of the metering pump 2 is fixedly connected to the melt blowing head 3. The processin...
