摘要： Disclosed herein is a duo-functional nonwoven composite having a support layer with a top surface and a bottom surface separated by a thickness. On the bottom surface of the support layer is a fibrous nonwoven web with all or a portion of the fibers being formed from a material which is soluble in a fluid such as water. At least a portion of the fibers extend through the thickness of the support layer from the bottom surface and project beyond the top surface to give the top surface a cloth-like appearance. Upon wetting the top surface of the support layer by a fluid such as water, urine or menses, the soluble fibers begin to shrink and dissolve until all or a portion of the filaments have retracted back into and through the thickness of the support layer. In so doing, the applied fluid is transported substantially away from the top surface of the composite. As a result, when the material of the present material is used as a liner material for personal care products, it initially provides a surface which is more cloth-like and comfortable to the wearer. However, after being insulted, the soiled portion of the nonwoven dissolves and retracts back into the composite thereby giving a cleaner, dryer appearance as is more commonly found when using films.
摘要翻译：本文公开了一种双功能非织造复合材料，其具有顶部表面和底部表面被分隔一厚度的支撑层。在支撑层的底表面上是纤维非织造纤维网，其全部或部分纤维由可溶于诸如水的流体的材料形成。纤维的至少一部分从底表面延伸穿过支撑层的厚度并突出超过顶表面，以使顶表面呈布状外观。在通过诸如水，尿液或月经之类的流体润湿支撑层的顶表面时，可溶性纤维开始收缩和溶解，直到全部或一部分细丝缩回并穿过支撑层的厚度。这样做时，所施加的流体基本上远离复合材料的顶表面。结果，当本材料的材料用作个人护理产品的衬垫材料时，其最初提供了更为布状且对穿着者舒适的表面。然而，在被污染之后，非织造材料的污染部分溶解并缩回到复合材料中，从而产生更干净的干燥器外观，如在使用膜时更常见的那样。
