THERMOPLASTIC COMPOSITE LAMINATE AND ARTICLES MANUFACTURED THEREFROM
Disclosed are thermoplastic composite laminates comprising in order of: (a) a top layer composed of at least one polycarbonate sheet; (b) a fabric layer composed of a fabric comprising aromatic polyamide fibers and an adhesion aid; and (c) a bottom layer composed of at least one polycarbonate sheet; wherein the adhesion aid comprises polycarbonate oligomers having a weight average molecular weight of about 6500 or less.
Also disclosed are articles comprising or produced from the thermoplastic composite laminates.
APERTURED ELASTIC FILM LAMINATES
An elastic laminate is provided including at least one gathered outer facing layer of a fabric and an apertured elastic film attached thereto. The aperture film includes a series of alternating first and second segments that extend continuously along the direction of elasticity. The first segments of the film are substantially devoid of any apertures and the second segments are strewn with apertures of irregular size and shape. The regionally limited and irregular apertures are formed by the controlled rupturing of the film within those segments. The elastic laminate has excellent air-permeability and elastic properties.
ELASTIC SHEET FOR ABSORBENT ARTICLE AND ABSORBENT ARTICLE
An elastic sheet for an absorbent article includes a first fibrous layer disposed on a first surface of the elastic sheet, a second fibrous layer disposed on a second surface of the elastic sheet opposite to the first surface, and contractible elastic members secured between the first fibrous layer and the second fibrous layer. The first fibrous layer and the second fibrous layer each include continuous fibers of thermoplastic and gathers formed between adjacent ones of the elastic members. The gathers are disposed in an intersecting direction intersecting with a direction in which the elastic members extend. An average flexural rigidity value of the first fibrous layer and the second fibrous layer in accordance with a KES method is 0.003510.sup.4 to 0.02210.sup.4 (N.Math.m.sup.2/m). A thickness under a compression load to the gathers in accordance with the KES method is 0.22 to 1.5 mm.

ELECTRONIC DEVICE HAVING HOUSING
An electronic device includes a housing including a first plate, a second plate facing away from the first plate, and a lateral member surrounding a space between the first plate and the second plate; a display visible through at least part of the first plate; and a glass construction constructing at least part of the second plate. The glass construction includes a glass plate including a first face outwardly facing the housing and a second face facing away from the first face, an inorganic layer including a first roughness and constructed on the first face, a first polymer layer disposed between the first plate and the second face, an Optically Clear Adhesive (OCA) layer disposed between the second face and the first polymer layer, and a second polymer layer disposed between the first plate and the first polymer layer and including a third face and a fourth face.
MULTI-LAYERED ELASTIC AIR-PERMEABLE MATERIAL STRUCTURE
The present invention relates to a multi-layered elastic air-permeable material structure, including an elastic cloth and an elastic film, wherein the elastic cloth is constituted of polylactic acid, has a plurality of penetrating air vents, and has a weft-direction stretchability. The elastic film is constituted of a thermoplastic elastomer material, and it also has a plurality of penetrating air vents. An upper surface of the elastic film is entirely or partially adhered to a lower surface of the elastic cloth. In particular, the elastic film has an air permeability of 17-25 cc/sec per square centimeter, and the multi-layered elastic air-permeable material structure has an air permeability of 7-10 cc/sec per square centimeter. The present invention has the advantages of weft-direction stretchability and air permeability and is suitable for applying to close-fitting clothing or diapers to improve comfort and prevent sultriness and moisture.
