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.

Composite yoga mats and straps comprising a fabric sheet and loop holes and/or filament loops functioning as hand grips or appendage supports useful in the practice of yoga positions. The yoga straps or mats can to provide support, a stable surface, and moisture absorption for the practice of yoga.
The present invention relates to a method for improving the abrasion resistance of a spun-bonded nonwoven without substantially adversely affecting its hand or drape characteristics, by incorporating low melt binder fibers into the web during the laydown phase of the spun-bonded nonwoven production process. More specifically, improved abrasion resistance is achieved by intimately blending continuous binder fibers with the primary extruded fibers in a spun-bonded nonwoven web. Also encompassed within this invention is a spun-bonded nonwoven fabric having improved abrasion resistance and comprised of primary extruded fiber and low melt binder fiber such that the binder fiber comprises between about 1 and about 50 weight percent on weight of the spun-bonded nonwoven fabric.
