| 摘要 |
The present invention is directed to a method of forming a nonwoven fabric, which exhibits a pronounced durable three-dimensional image, permitting use of the fabric in floor underlayment of laminate floor systems so as to reduce acoustic feedback under normal use (walking) due to sound absorption and leveling of the floating laminate floor system applications. In particular, the present invention contemplates that a fabric is formed from a precursor web comprising at least one support layer or scrim, whereby when subjected to hydroentanglement on a moveable imaging surface of a three-dimensional image transfer device, an enhanced product is achieved. By formation in this fashion, hydroentanglement of the precursor web results in a more pronounced three-dimensional image, an image that is durable to abrasion and distortion.
