3 is a cross-sectional view showing another embodiment of the skin material of the present invention.
Fig. 4 is a manufacturing process diagram showing an embodiment of the second production method of the skin material of the present invention. Fig.
The skin material of the present invention will be described.
As described above, the skin material of the present invention is a skin material having a base material and a polymer material-containing layer disposed on the surface side of the base material, and has a minute concave portion with a depth of 30 to 130 탆 on the surface of the polymer material- The ratio of the projected area of the concave portion to the total projected area standard of the surface of the material-containing layer is 5 to 20%. By such a constitution, the plate thickness is uniform, the appearance is not damaged, and the feel of moist feeling or smooth feeling is improved. Here, the polymer material-containing layer may have a conventionally known uneven shape on the surface thereof, and when the minute rugged shapes are formed to overlap with each other, the tactile sensation is improved as compared with the case where only the rugged shape is formed, Also, the appearance formed by the rugged shape is not damaged. The rugged shape may be, for example, a leather rugged shape taken from the inversion of leather, or a rugged shape of a large pattern giving a regular, semi-regular shape to give designability. The polymer material-containing layer may have a single-layer structure or a laminate structure of two or more layers. The minute concave portion formed on the surface of the polymer material-containing layer is not particularly limited as long as the depth is 30 to 130 占 퐉. For example, when the depth of the concave portion is 1, the interval (pitch) And a maximum diameter of 3 to 4 is preferable. If the maximum diameter of the concave portion exceeds 520 탆, even if the interval (pitch) of the concave portion is 30 to 1300 탆, it is easy to visually confirm the concave portion, and the appearance may be impaired. Further, when the interval (pitch) of the concave portions is less than 30 占 퐉 and the maximum diameter is less than 90 占 퐉, the concave portions are less than the size that can be sensed when a person touches them. Even if the maximum diameter of the concave portion is 90 to 520 占 퐉, if the interval (pitch) of the concave portions exceeds 1300 占 퐉, the interval (pitch) is excessively spaced and the touch may not be excellent.
More specifically, it is more preferable that the depth of the concave portion is 50 to 110 占 퐉, the interval (pitch) of the concave portion is 50 to 300 占 퐉, and the maximum diameter of the concave portion is 90 to 130 占 퐉. It is more preferable that the depth of the concave portion is 50 to 110 占 퐉 and the interval (pitch) of the concave portions is irregular and uneven in the range of 50 to 300 占 퐉 and the maximum diameter of the concave portion is 90 to 130 占 퐉. It is preferable that the concave portion has an R-shaped edge. In the case of not having an R shape, a rough touch may be felt, which is not preferable. Furthermore, it is preferable that the radius of curvature of the R shape is 30 to 100 mu m from the viewpoint of improvement in tactility such as smoother and more flexible. It is preferable that the above-mentioned polymer material-containing layer contains fine particle powder having an average particle diameter smaller than the maximum diameter of the concave portion and at least part of the fine particle powder is exposed on the surface of the polymer material-containing layer from the viewpoint of further improving tactility.
In the case of using the fine particle powder having an average particle size larger than the size of the minute concave portion, since the concave portion is buried by the fine particle powder, there is a case that the feeling is not excellent, and if the contained fine particle powder is not exposed on the surface Excellent touch can not be obtained. The average particle diameter of the above-mentioned fine particle powder is preferably 8 to 30 탆. When the average particle diameter is less than 8 占 퐉, the volume ratio of the fine particle powder buried in the polymer material-containing layer becomes large and the surface exposure is small,
If the addition amount is not increased, the feel is not improved. On the other hand, when the average particle diameter exceeds 30 탆, the recessed portion is buried by the fine particle powder, so that the feeling may not be excellent. In addition, the content of the fine particle powder in the polymer material- M < 2 >. When it is less than 0.1 g / m < 2 >, there is no difference in superiority over the improvement of touch,
, There is a possibility that the color and the gloss of the polymer material-containing layer are changed, which may cause adverse effects. The proportion of the fine particle powder not exposed on the surface increases in the polymer material-containing layer, which may lower the wear resistance of the polymer material-containing layer.
