| 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 secondary carpet backing of carpet backing systems so as to reduce deformation under normal l use (walking) and provide better coverage in carpet system applications. In particular, the present invention contemplates that a fabric is formed from a precursor web (P) comprising a spunbond and/or cast scrim, which when subjected to hydroentanglement on an imaging surface (24), 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. |
