A shaped nonwoven fabric comprises continuous spunbond filaments made by directly forming the spunbond filaments into a web in a single process. The fabric has an array of discrete surface features such as apertures or projections, or both. The spunbond filaments are bonded together with an adhesive polymeric component so that the shape of the fabric is retained. The fabric can be engineered to have particular fluid handling properties, strength properties, abrasive properties and aesthetic properties. Articles such as personal care products, garments, medical products and cleaning products are also disclosed. |

DETAILED DESCRIPTION Accordingly, an object of the present invention is to provide an improved shaped nonwoven fabric and process for making the same.
Another object of the present invention is to provide an improved shaped nonwoven fabric made with spunbond filaments and a process for making the same.
Another object of the present invention is to provide an improved nonwoven fabric having apertures or projections, or both, and a process for making the same.
Still another object of the present invention is to provide a nonwoven fabric with improved fluid-handling properties.
Yet another object of the present invention is to provide improved shaped nonwoven articles such as personal care articles, garments, medical articles, and cleaning articles, and the like.
Thus, the present invention provides a shaped nonwoven fabric, a process for making the nonwoven fabric, and articles made with such fabric.
The nonwoven fabric of the present invention is made by directly forming spunbond filaments into a web in a single process and has an array of discrete surface features such as apertures or projections, or both.
The spunbond filaments are bonded together with an adhesive polymeric component so that the shape of the fabric is retained.
The fabric of the present invention can be engineered to have particular fluid handling properties.
The surface features of the fabric can be designed to direct flow 3-dimensionally through the fabric.
The features of the fabric can also be designed to enhance the strength, resilience, abrasive properties, and the aesthetic properties of the fabric.
The fabric of the present invention also can be designed to perform as a separation layer in various applications for improved skin dryness of the wearer.
Other advantages of the fabric of the present invention are explained below.
More particularly, the nonwoven fabric of the present invention includes meltspun and drawn continuous spunbond polymeric filaments which extend substantially continuously along the length of the fabric
