摘要： A process for making nonwoven fabric including the steps of meltspinning continuous multicomponent polymeric filaments, drawing the multicomponent filaments, at least partially quenching the multicomponent filaments so that the multicomponents have latent helical crimp, activating the latent helical crimp, and thereafter, forming the crimped continuous multicomponent filaments into a first nonwoven fabric web. By crimping the filaments before the web formation, shrinkage of the web after formation is substantially reduced and the resulting fabric is substantially stable and uniform. In addition, the resulting fabric can have a relatively high loft. The crimp activating step can include heating the multicomponent filaments and preferably includes drawing the multicomponent filaments with a flow of heated air to activate the latent helical crimp. The resulting fabric can form relatively high loft materials useful as a fluid management layer for personal care absorbent articles or can form cloth-like fabric useful as cover materials and garment material. In addition, a nonwoven fabric comprising continuous single and multicomponent filaments and proces for making same are provided. Still further, a multilayer nonwoven fabric with continuous multicomponent filaments and process for making same are provided. The degree of crimp in the filaments can be varied from layer to layer to produce composite webs with particular fluid handling properties.

摘要： 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.

摘要： The present invention provides a durable, launderable hydroentangled composite that is highly suitable for skin-contacting uses. The composite is a hydrogentangled composite which is pattern bonded. The composite contains two filamentous web layers containing crimped continuous filaments and a cellulosic layer containing cellulosic fibers, and the cellulosic layer is disposed between the filamentous web layers. The composite fabric is launderable as demonstrated by the fact that the composite loses less than about 2% of its opacity, based on the initial opacity of the composite, when subjected to one laundering cycle in accordance with the ASTM 2724-87 washing and drying procedure. Additionally provided is a process for producing the composite.
