研究了水射流压力分布（WJPP）和初始腹板几何形状对水纠缠织物性能的影响。在相同的总压力下，不同的水射流剖面产生了不同的腹板结构（通过平行、交叉和气成地层获得）并发生了水纠缠。复合结构也可以通过将不同的网状结构结合在一起，然后进行水缠结。然后根据关键物理性能对织物进行表征。虽然总压力可能是恒定的，但WJPP会影响织物的拉伸性能，特别是那些含有空气成布结构的织物。结果还表明，为了生产高强度织物，在几乎相同的总压力下，腹板两侧应进行水纠缠。MD/CD强度比表明，各向同性程度最高的织物是空气铺设的、交叉铺设与平行铺设相结合的复合腹板结构。
The effect of a water jet pressure profile (WJPP) and initial web geometry on the properties of hydroentangled fabrics is investigated. Different web structures (obtained by parallel, cross, and air-laid formation) are produced and hydroentangled at the same total pressure but with different water jet profiles. Composite structures are also made by combining different web structures followed by hydroentangling. The fabrics are then characterized in terms of key physical properties. Although the total pressure may be constant, the WJPP influences the tensile properties of fabrics, especially those containing air-laid structures. The results also suggest that to produce high tenacity fabrics, the webs should be hydroentangled on both sides at almost the same total pressure. The MD/CD strength ratios indicate that the most isotropic fabrics are air-laid, composite web struc tures combining cross and parallel-laid webs.
