PROBLEM TO BE SOLVED: To provide an artificial leather rich in durability, having a surface so smooth providing good feeling, and appropriate for a wear fabric, a chair upholstery, and a vehicle interior material.SOLUTION: A depressed hole 24 having an inner diameter (d) of not less than 0.3 mm and not greater than 2 mm is formed on the surface of an artificial leather constituted by applying a thermoplastic resin 13 to a fabric 12 composed of a thermoplastic synthetic fiber 11. A peripheral edge 16 of the depressed hole 24 and an inner wall surface 18 of the inside are composed of a heat-molten mixture 15 of the thermoplastic synthetic fiber 11 and the thermoplastic resin 13. The peripheral edge 16 of the depressed hole 24 is on a position hollowed from the surface of the artificial leather. The inner diameter (d) of the depressed hole 24 is gradually narrowed toward the inside 19 of the depressed hole 24 from the peripheral edge 16 of the surface of the artificial leather. It is preferable that a minimum inner diameter (d) of the depressed hole 24 is less than 1 mm. A pattern can be stippled with the depressed holes 24 on the surface of the artificial leather. The depressed hole 24 may be processed to be an open hole 14 by heat-melting to open a hole bottom 25 thereof.SELECTED DRAWING: Figure 6

    【課題】耐久性に富み、表面が平滑で肌触りがよく、衣料生地や椅子張り地、車両内装材に適した人造皮革を提供する。【解決手段】熱可塑性合成繊維11に成る布帛12に熱可塑性樹脂13を付与して成る人造皮革の表面に、内部口径(d)が0.3mm以上で2mm以下の陥没穴24を形成する。その陥没穴24の周縁16と内部の内壁面18を、熱可塑性合成繊維11と熱可塑性樹脂13との熱溶融物15によって構成する。陥没穴24の周縁16は、人造皮革の表面から窪んだ位置にする。陥没穴24の内部口径(d)は、人造皮革の表面の周縁16から陥没穴24の内部19に向けて漸次狭める。陥没穴24の最小内部口径(d)は1mm未満にすることが望ましい。陥没穴24によって人造皮革の表面に絵柄を点描することが出来る。陥没穴24は、その穴底25を加熱溶融して切開して貫通孔14としてもよい。【選択図】図6
