    • An apparatus for the preparation of bonding fibers, especially for the production of nonwovens by a wet-lay process, wherein a polymer dispersion, containing an anionic or nonionic dispersant, and an aqueous solution, containing a dissolved cationic precipitant, are combined to cause fiber formation from precipitated polymer particles, which apparatus includes a feed funnel spaced above the bottom of a homogenization vessel with both a nozzle for introducing the polymer dispersion and a metering device for the precipitant, which are so arranged and aimed into the funnel that in co-operation with a stirrer a vortex is produced in a column of liquid in the feed funnel, and fibers are formed and broken up while passing through a turbulence chamber, located at the bottom of the funnel, and a gap into a homogenization chamber.
    • 用于制备粘合纤维的装置,特别是用于通过湿法生产非织造布的装置,其中将含有阴离子或非离子分散剂的聚合物分散体和含有溶解的阳离子沉淀剂的水溶液组合以引起纤维 由沉淀的聚合物颗粒形成,该装置包括在均质化容器的底部间隔开的进料漏斗,其具有用于引入聚合物分散体的喷嘴和用于沉淀剂的计量装置,其被布置和瞄准到漏斗中, 用搅拌器操作,在进料漏斗中的液体柱中产生涡流,并且在通过位于漏斗底部的湍流室和形成均匀化室的间隙中形成纤维并将其分解。
