Abstract: Nonwoven fibrous webs include elastic filaments such that the web as a whole exhibits elastic properties when stretched. The webs include a multiplicity of nonwoven fibers and at least one elastic filament entangled with at least a portion of the nonwoven fibers to form a self-supporting, cohesive, elastic nonwoven fibrous web. Methods of making such elastic nonwoven fibrous webs using hydro-entanglement, and uses of such webs to form articles are also described.

Abstract: The purpose of this disclosure is to provide a process for producing stretch nonwoven fabric having excellent stretchability. This production process has the following configuration. The process for producing stretch nonwoven fabric comprises: a step in which nonwoven fabric to be treated which comprises stretchable fibers and extensible fibers is unevenly stretched, while being conveyed, so that nonwoven fabric having both higher stretched regions and lower stretched regions is formed; and a step in which the nonwoven fabric having both higher stretched regions and lower stretched regions is heated for 0.1-10 seconds at a temperature which is 40° C. or higher but is lower than the melting point of the stretchable fibers. The production process is characterized in that in the nonwoven fabric having both higher stretched regions and lower stretched regions, the higher stretched regions and the lower stretched regions are parallel to the direction perpendicular to the conveying direction and are present alternately in the conveying direction.

Abstract: A stretchable elastic laminate including at least one nonwoven fabric layer, and at least one elastomeric material extruded as a melt onto a major surface of the nonwoven fabric to form an elastic layer bonded to the surface of the nonwoven fabric. The nonwoven fabric layer has first and second bonding zones formed on the surface thereof, which have first and second bonding strengths. The elastic layer is bonded to the surface of the nonwoven fabric such that the elastic layer forms a stronger bond with the first bonding zone on the surface of the nonwoven than the bond formed between the elastic layer and the second bonding zone on the surface of the nonwoven. The lightly bonded areas of the elastic laminate provide increased elongation in the cross direction and improved recovery after stretch, while the more strongly bonded areas provide adhesive strength. Also disclosed is a method of forming a stretchable laminate having increased elongation and improved recovery after stretch.

Abstract: A composite material as a sheet material is described, being relatively cheap, most useful as a raw material of a sanitary product or the like, such as underwear, dust-proof mask or dispensable paper diaper, etc., and good in processability, stretchability, gas-permeability, softness, and touch. The composite material is formed by laminating a stretchable layer and a conjugate spunbonded nonwoven fabric including conjugate fibers including a low-melting-point component and a high-melting-point component. The conjugate fibers are partially bonded to each other by thermocompression, wherein each bonded portion has fine folded structures including alternate hill and valley regions in the CD, and the distance between neighboring hills is 100-400 μm in average. The conjugate spunbonded nonwoven fabric exhibits stretchability through the spread of the fine folded structures, and has, at 5% elongation, a CD-strength of 0.1 N/5 cm or less and an MD/CD strength ratio of 200 or more.
