    • A nonwoven fabric comprises continuous polymer filaments of 0.5 to 3 denier that have been hydroentangled in a complex matrix for interconnecting filament loops, and that is otherwise substantially free of knotting, or of otherwise wrapping about one another. A process for making a nonwoven fabric comprises continuously extruding polymer filaments of 0.5 to 3 denier onto a moving support, pre-entangling the filaments with water jets, and entangling the filaments with a second set of water jets on a three-dimensional image transfer device. An apparatus for making a nonwoven fabric comprises means for continuously extruding substantially endless polymer filaments of 0.5 to 3 denier onto a moving support to form an unbonded web, a pre-entangling station for entangling the web with a plurality of water jets, and a plurality of water jets for final entanglement of the filament web on a three-dimensional image transfer device. In another aspect of the present invention, plural precursor webs, each comprising polymeric filaments, can be employed to form a laminated nonwoven fabric.
    • 非织造织物包含0.5至3旦尼尔的连续聚合物长丝,其已经被水解缠绕在用于互连丝线圈的复合基质中,并且否则基本上不会打结或彼此缠绕。 制造无纺布的方法包括将0.5至3旦尼尔的聚合物长丝连续挤出到移动的支撑件上,用水射流预缠绕长丝,并将第二组水射流缠绕在三维图像转印装置上 。 一种用于制造无纺织物的装置包括用于将0.5至3旦尼尔的基本上环状的聚合物长丝连续挤出到移动的支撑件上以形成未粘合的网的装置,用于与多个水射流缠绕网的预缠结站,以及多个 的水射流,用于三维图像转印装置上的丝网的最终缠结。 在本发明的另一方面,可以使用多个包含聚合物长丝的前体纤维网,以形成层压无纺织物。
