摘要： A laminated non-woven fabric and a manufactured article using the laminated non-woven fabric are provided. The laminated non-woven fabric may cause no damage to a surface of the non-woven fabric, set a machining temperature during point thermal compression bonding to be high, have tender hand feeling and sufficient interlayer peeling strength without damaging the hand feeling, have less fluff, do not weld or wind for an embossing roll during the point thermal compression bonding, and may be stably produced in the long term. Additionally, a laminated non-woven fabric with high impregnated amount (liquid preservation amount) of a liquid component in a purpose requiring water absorbability, and a manufactured article using the laminated non-woven fabric are provided. A laminated non-woven fabric and a manufactured article obtained by using the same are provided. The laminated non-woven fabric is formed by clamping a fibrous layer B between two of fibrous layer A, wherein the fibrous layer B is obtained by using a fiber melting or softening at 120°C or less, and fibrous layer A includes a fiber neither melting nor softening at 120°C or less, in which the fibrous layer A and the fibrous layer B are integrated through point thermal compression bonding, and interlayer peeling strength between the fibrous layer A and the fibrous layer B ranges from 0.3 Newton (N)/25 millimeters (mm) to 4.0 N/25 mm.

摘要： Provided is a nonwoven fabric being high in bulk and good in texture and having both a capability of highly efficiently collecting dust and the like and such a low pressure loss characteristic that the intake resistance occurring when gas passes through a filter is low.
The nonwoven fabric is a blended filament nonwoven fabric comprising a blend of two types of filaments, wherein the two types of filaments are constituted of thermoplastic resins different from each other, an average fiber diameter obtained by dividing the total value of fiber diameters of the filaments present in the nonwoven fabric by the number of the constituent filaments is 0.1 to 10 µm, and the nonwoven fabric has a specific volume of 12 cm 3 /g or more; the blended filament nonwoven fabric, wherein the ratio of the number of constituent filaments having fiber diameters of 0.1 to 3 µm is 50% or more of the filaments constituting the nonwoven fabric, and the ratio of the number of constituent filaments having fiber diameters exceeding 3 µm is 50% or less of the filaments constituting the nonwoven fabric; or the blended filament nonwoven fabric, wherein the nonwoven fabric is produced by a melt-blowing process.
