    摘要： The present invention provides a processing apparatus and a processing method capable of producing a point-through-air nonwoven fabric wherein hot air is allowed to penetrate through spots of a web or a sheet-like material and fibers at the penetration site are heat-bonded. Specifically, the present invention provides a processing apparatus for hot-air treatment nonwoven fabric, comprising: a rotating running endless belt with holes, a hot-air blowing apparatus which blows out hot air from an internal side of the endless belt with holes toward an outer side thereof, and an endless belt for fiber conveyance which is arranged on a side opposite to the hot-air blowing side of the hot-air blowing apparatus across the endless belt with holes and rotates with passing the hot-air therethrough.

    摘要： Present invention provides an air filter material using a laminated electret nonwoven fabric subjected to electret processing in which one layer or a plurality of layers of nonwoven fabrics (referred to as nonwoven fabric B) including fibers having a mean fiber diameter in the range of 10 micrometers to 100 micrometers and being larger than a mean fiber diameter of fibers constituting nonwoven fabric A are laminated on at least one side of a nonwoven fabric (referred to as nonwoven fabric A) obtained by mixing two kinds of fibers having a mean fiber diameter in the range of 0.1 micrometer to 15 micrometers and having a different melting point (fibers having a lower melting point are defined as fibers D and fibers having a higher melting point are defined as fibers E), and a laminated electret filter material having a low pressure loss and a high collection efficiency. The filter material is suitably used for a medical mask, an industrial mask, a general purpose mask or the like.

    摘要： A stretchable laminated sheet with hydrophilic properties, which particularly has an excellent feeling and stability in wearing and is capable of efficiently enhancing the effect and efficacy brought about by a liquid component on a skin or other object, when the stretchable laminated sheet is impregnated with the liquid component and wet and then used on the skin or other object. A stretchable laminated sheet, which is obtained by partially thermocompression-bonding and laminating a hydrophilic short fiber layer extensible in at least one direction and an microfiber layer having a elastomer long fiber of a fiber diameter of 15 µm or less at 50% or more by weight, wherein discontinuous and regular concave and convex parts caused by the partial thermocompression bonding are formed on a surface of the hydrophilic short fiber layer that is exposed on one surface of the stretchable laminated sheet, the total area of the concave parts is in a range of 3 to 40% of the area of the surface of the hydrophilic short fiber layer, and at least the elastomer long fiber of the microfiber layer is softened and consequently joined to a fiber constituting the hydrophilic short fiber layer in a sheet thickness direction of a section where the concave parts exist, whereby the hydrophilic short fiber layer and the microfiber layer are integrated with each other.
