Airlaid composite sheet material

Provided is a composite sheet that is particularly useful as an AQDL component in absorbent articles. The composite sheet includes a fluid acquisition component and an airlaid component. The airlaid component may include one or more airlaid layers that are successively formed overlying each other. Each of the airlaid layers are adjacent to, and in direct contact with, immediately adjacent layers of the airlaid component so that adjacent layers are in fluid communication with respect to each other. The fluid acquisition component includes a nonwoven fabric comprising a carded nonwoven fabric comprised of a plurality of staple fibers that are air through bonded to each other to form a coherent nonwoven fabric. The airlaid layer(s) include a blend of cellulose and non-cellulose staple fibers. The staple fibers may be bicomponent fibers having a polyethyelene sheath and a polypropylene or polyethylene terephthalate core, and mixtures of such fibers.

In a skin material, a front face of a first fibrous base material is a first color and a front face of a second fibrous base material is a second color. The second fibrous base material is laminated on a back face of the first fibrous base material. A through hole of the first fibrous base material penetrates the first fibrous base material in a laminating direction. A dimension of the through hole in a first direction is set to a first value (N1). A dimension of the through hole in a second direction is set to a second value (N2). A dimension of the through hole in the laminating direction is set to a third value (N3). The first value (N1) and the second value (N2) are set to be 0.38 times or more and 12 times or less with respect to the third value (N3).

ARTIFICIAL LEATHER

The present disclosure is relates to an artificial leather. The artificial leather includes multi-layer thermoplastic polyurethane (TPU) mesh layers. Fiber fineness of the TPU mesh layers ranges from 5 μm to 30 μm, and peeling strength of the TPU mesh layers is greater than 2.5 Kg/cm.

Artificial Leather and Method for Manufacturing Same

An artificial leather is provided that, due to excellent texture and mechanical strength (abrasion resistance, etc.), can be appropriately used in, for example, clothing products, or sheets of skin material or interior material, etc. for interiors, automobiles, airplanes, rail cars, etc. One embodiment of the present invention is an artificial leather that includes a fiber sheet and a polyurethane resin, wherein the fiber sheet includes a scrim that is a woven or knitted fabric, and a fiber layer (A) that constitutes a first outer surface of the artificial leather, such that in a thickness direction cross-section of the fiber layer (A), the ratio (d/D) of the total area (d) of the polyurethane resin that forms a closed shape having an area of 100 μm2 or more to the total area (D) of the polyurethane resin satisfies the following formula (1): 5≤(d/D)×100≤50 (%).
