Measuring apparatus for moisture transmission performance of wadding fiber assembly

一种絮填纤维集合体湿传递性能的测量装置

Abstract

The invention relates to a measuring apparatus for the moisture transmission performance of a wadding fiber assembly. The measuring apparatus comprises a heat insulation protection seat. The upper part of the heat insulation protection seat is provided with a two-section groove; the lower layer of the groove is a constant temperature water bath tank; a thermal resistance filament is fixed in the constant temperature water bath tank; a simulated skin is covered over an upper liquid level of the constant temperature water bath tank; a first temperature sensor and a first humidity sensor are arranged above the simulated skin; the upper layer of the groove is in immovable fit with a sample cylinder; the lower end of the sample cylinder is provided with a mesh interlayer; the interior surface of the sample cylinder and the outer surface of a pushing cylinder are in sliding fit; the upper end of the pushing cylinder is opened, the lower end of the pushing cylinder is provided with a mesh interlayer, and a second temperature sensor and a second humidity sensor are fixedly arranged above the mesh interlayer; and the thermal resistance filament, the first temperature sensor, the second temperature sensor, the first humidity sensor, the second humidity sensor, a refrigerator and a fan are connected with a control circuit and are connected with a computer through a signal pickup assembly for realization of data processing.
本发明涉及一种絮填纤维集合体湿传递性能的测量装置,包括隔热保护座,隔热保护座上部设有两段式的凹槽,凹槽下层是恒温水浴池,恒温水浴池中固定设置热阻丝,恒温水浴池的上液面处覆盖模拟皮肤,模拟皮肤的上方设有第一温度传感器和第一湿度传感器;凹槽上层与试样筒紧固配合,试样筒的下端设有网眼隔层,试样筒的内侧面与推筒的外侧面滑动配合,推筒上端开放,下端设有网眼隔层,网眼隔层上方固定设置第二温度传感器和第二湿度传感器;热阻丝,第一、二温度传感器,第一、二湿度传感器,制冷器和风扇与控制电路连接,通过信号采集装置与计算机相连进行数据处理。
