    • A die for melt-blowing apparatus, which has a die body, a nozzle piece, and a lip plate. The nozzle piece is divided into plural temperature-controlling regions in a direction crosswise to a spinning direction. A temperature sensor is used to measure the temperature at a portion surrounding a nozzle orifice in the nozzle piece in each of the divided temperature-controlling regions. A heated gas is applied directly to the nozzle piece for controlling the temperature of the portion surrounding the nozzle orifice to a predetermined temperature. Using this die body, a melt-blown non-woven fabric with a uniform distribution of the weight per unit area can be easily obtained.
    • 一种用于熔喷设备的模具,其具有模具本体,喷嘴件和唇板。 喷嘴片在与旋转方向交叉的方向上分为多个温度控制区域。 温度传感器用于测量在每个分割的温度控制区域中喷嘴片周围喷嘴孔的部分处的温度。 将加热的气体直接施加到喷嘴件,以将喷嘴孔周围的部分的温度控制到预定温度。 使用该模具体,可以容易地得到每单位面积重量均匀分布的熔喷无纺布。
