A study was conducted on a commercial grade hydroentanglement system to assess the effects of jet strip configuration in terms of both orifice diameter (0.10 mm, 0.12 mm, and 0.14 mm) as well as the number of orifices per inch (40 and 50) on the properties of resultant nonwoven cotton fabrics at various hydroentanglement pressures (0, 5.0, 7.5, 10.0, 12.5, and 14.0 MPa). It was found that an increase in the energy applied to the fabric web resulted in a nonwoven with increased absorbency. The results of air permeability testing indicate that a combination of variations in the orifice diameter and the number of orifices per inch as well as the energy applied determine the overall air permeability of the fabric. Tensile testing revealed that increasing the energy applied to the fabric resulted in increased strength in both the machine and cross directions and decreased elongations. These results indicate that the mechanical and performance characteristics of nonwoven cotton fabrics produced by hydroentanglement may be manipulated to obtain the desired characteristics for the targeted end-use application.

完全由棉纤维组成的非织造布的优化水刺工艺参数

对商业级水刺系统进行了一项研究，以评估喷射带配置在孔直径（0.10 毫米、0.12 毫米和 0.14 毫米）以及每英寸孔数（40 和 50）方面的影响。所得非织造棉织物在各种水刺压力（0、5.0、7.5、10.0、12.5 和 14.0 MPa）下的性能。发现增加施加到织物网的能量导致非织造布具有增加的吸收性。透气性测试的结果表明，孔口直径和每英寸孔口数量以及施加的能量的变化共同决定了织物的整体透气性。拉伸测试表明，增加施加到织物上的能量会导致纵向和横向的强度增加并降低伸长率。这些结果表明，可以操纵通过水刺法生产的非织造棉织物的机械和性能特性，以获得目标最终用途应用所需的特性。
