    • Apparatus (100, 101, 102) and die cartridge assembly (18, 44, 45, 47) adapted for use with same for producing fibrous material (212). The apparatus (100) comprises a removably attachable die cartridge assembly (18) that adapts to conventional spunmelt equipment. The die cartridge assembly (18) is removably positionable beneath an extrusion body (10) for effecting formation of fibrous material by fibrillation of polymer films. The cartridge assembly (18) includes at least one polymer passage (19) communicating with a molten polymer source (10) for directing molten polymer onto at least one film forming surface (20, 28) defined by the cartridge assembly (18), and also defines at least one gas passage (222, 22, 30) communicating with a gas source (16) for directing pressurized gas (220) against the molten polymer (210) in the form of a film for effecting formation of the fibrous material (212).
    • 设备(100,101,102)和适于与其一起使用的模具盒组件(18,44,45,47)用于生产纤维材料(212)。 该装置(100)包括适于常规纺粘设备的可拆卸地安装的模盒组件(18)。 模具盒组件(18)可移除地定位在挤出体(10)的下面,用于通过聚合物膜的原纤维化来形成纤维材料。 盒组件(18)包括与熔融聚合物源(10)连通的至少一个聚合物通道(19),用于将熔融聚合物引导到由盒组件(18)限定的至少一个成膜表面(20,28)上;以及 还限定了与气体源(16)连通的至少一个气体通道(222,22,30),用于将加压气体(220)以薄膜形式引导到熔融聚合物(210)上,以形成纤维材料( 212)。
