摘要： A system for hydroentangling a fabric material, while reducing the incidence of jet streaks therein, is provided. Various embodiments of the present invention provide an elongate hydroentangling jet strip spaced apart from the fabric material and extending substantially across a width of the fabric perpendicular to the processing direction. The strip defines a first row of orifices, each having a first diameter. The first plurality of orifices is spaced apart along a width of the elongate strip. The strip further defines a second plurality of orifices disposed downstream from the first plurality of orifices in the processing direction and offset therefrom along the width of the elongate strip. The second plurality of orifices each define a second diameter smaller than the first diameter such that fluid streams generated thereby impart a correspondingly smaller impact force on the fabric material than fluid streams generated by the first plurality of orifices.

摘要： The invention provides durable nonwoven fabrics comprising staple fibers. Methods of preparing durable nonwoven fabrics based on staple fibers are also provided. The methods can include the steps of at least one of needle punching and hydroentangling. The durable nonwoven fabric can be subjected to additional bonding techniques, such as resin bonding and/or thermal bonding. The durable nonwoven fabrics of the invention provide improved durability over conventional nonwoven fabrics. Further advantages of the inventive nonwoven fabrics include maintaining the smooth surface qualities of the fabric and desirable feel of the fabric even with the enhanced durability. The inventive nonwoven fabrics can also be subjected to additional post-processing techniques that conventional nonwoven fabrics would otherwise be unable to withstand. Further, inks and/or dyes can more readily become adhered to the smooth nature of the surfaces of the inventive durable nonwoven fabrics.
摘要翻译：本发明提供了包含短纤维的耐用非织造织物。还提供了制备基于短纤维的耐用非织造织物的方法。所述方法可以包括以下步骤中的至少一种：针刺和水刺。耐久性非织造织物可以经受另外的粘合技术，例如树脂粘合和/或热粘合。本发明的耐用非织造织物提供比常规无纺布更好的耐久性。本发明的无纺布的其它优点包括即使具有增强的耐久性，也能保持织物的光滑表面质量和织物的期望感觉。本发明的非织造织物还可以进行额外的后处理技术，其中常规非织造织物否则将不能承受。此外，油墨和/或染料可以更容易地粘附到本发明耐久性非织造织物的表面的光滑性质上。
