- the width Q of the fine protrusions 11 in the fine unevenness 9 is approximately 30 ⁇ m
- the height R of the fine protrusions 11 in the fine unevenness 13 is approximately 15 ⁇ m.
- the shape of the convex portion 3 is basically circular in plan view (viewed from above in FIG. 3), but is not circular (perfect circle) such as an ellipse or an oval. There is also.
- the width Q of the portion with the largest dimension is 30 ⁇ m.
- the width Q of the fine protrusion 11 in FIG. 3 is the distance between the rising portions of the fine protrusion 11 from the bottom of the fine recess 13.
- the width H of the convex portion 5 in FIG. 1 is also the distance between the rising portions from the bottom of the concave portion 7 of the convex portion 5.
- Examples of the material of the article 1 include PP (polypropylene), ABS (acrylonitrile / butadiene / styrene), AES (acrylonitrile / ethylene / styrene), ASA (acrylonitrile / styrene / acrylate), POM (polyacetal), PA. (Polyamide), PC (polycarbonate) and the like.
- the article 1 is formed by injection molding using such a thermoplastic resin.
- the surface on which the unevenness 3 of the article 1 is formed as shown in FIG. 1 is touched with the belly 15a as the human skin of the finger 15, there is no unevenness and the surface is smooth.
- the surface structure is such that the ratio (contact rate) of the area where the finger 15 and the article 1 are in contact with each other under the same conditions is in the range of 35% to 90%.
- the tactile sensation of the finger is a sense based on sensory information such as pressure, pain, and temperature.
- the surface shape of the finger including fingerprints), the types and distribution of finger sensory receptors, the contact state between the article and the finger (pressure (Including spatial and temporal changes).
- the contact rate S increases, but when the human finger 15 touches the surface of the article 1, it is generally pressed with a force of 200 g weight (1.96 N). In this embodiment, the contact rate when the surface of the article 1 is touched with a force of 200 g is used.
- the contact rate S described above indicates that the belly of the finger when the finger is touched by a force of 200 g in the region of the length H of the article having irregularities formed on the surface is the convex portion 5.
- S (h1 + h2 + h3 +... + Hn) / H It becomes.
- the contact rate tends to be too high, so the width of the recess 7 has to be widened, and there is a rough feeling. Increases and looks worse.
- a specified contact rate S can be obtained, and the appearance can be improved.
- FIG. 5 is a cross-sectional view showing a specific surface structure of the article 1 that is closer to the real thing, and represents the distribution of the depth [nm] with respect to the scanning distance [ ⁇ m] in the direction along the article surface.
- the upper periphery of the fine convex portion 11 in the fine unevenness 9 formed at the tip of the convex portion 5 and the upper periphery of the convex portion 5 in the unevenness 3 are the surface of the article 1 by the belly 15 a of the finger 15. This is a portion where the finger 15 and the article 1 come into contact with each other.
- FIG. 6 shows that “moist feeling” as an index of “comfort” when touching the surface of the article 1 with the belly 15 a of the evaluator's finger 15, with a score of 5 being the most “moist feeling”.
- the circle mark corresponds to the case where the fine unevenness 9 is provided on the convex portion 5 of the unevenness 3
- the mark x corresponds to the case where only the unevenness 3 is provided without providing the fine unevenness 9.
- the contact rate is generally in the range of 35% to 90% when the standard score is about 3.0 or more as “moist feeling”.
- FIG. 7 is an example of a cross-sectional shape of an article (automobile part) 1 with a contact rate of 48%.
- the surface shape of the article 1 has fine irregularities 9 formed on the upper portions of the convexities 5 of the irregularities 3. .
- the fine irregularities 9 include fine convex portions 11 and fine concave portions 13.
- FIG. 8A shows the contact rate with respect to the unevenness 3 on the surface of the article in the absence of the fine unevenness 9
- FIG. 8B shows the contact rate with respect to the fine unevenness 9 provided on the upper portion of the convexity 5 of the unevenness 3.
- the contact rate with respect to the unevenness 3 is set to 60%
- the frictional force [N] is expressed by (pressure [Pa] ⁇ friction coefficient ⁇ contact area [m 2 ]).
- the input (pressure) can be constant as described above, and the friction coefficient is the same material. Since it becomes constant by assuming, the frictional force can be predicted by the contact area of the finger with the surface of the article. Further, since the contact area can be regarded as a constant area of the belly of the finger, a portion where the uneven shape portion on the surface of the article and the finger actually contacted can be measured and used as a contact rate.
- the uneven surface shape of the article surface is such that the ratio of the area where the finger contacts the article is in the range of 35% to 90%, so that the person touched the article. Occasionally, it can be a pleasant touch such as “soft”, “moist”, “smooth” like a skin material.
- Comfortable tactile sensations such as “soft”, “moist”, and “smooth” can be further improved.
- the unevenness 3 on the surface of the article has the convex portion 5 and the concave portion 7, and the finer pitch is finer than the concave and convex portion 3 formed of the convex portion 5 and the concave portion 7 on the upper portion of the convex portion 5.
- the depth P of the unevenness 3 is set to 70 ⁇ m or more. For this reason, the unevenness 3 is sharpened and the aesthetic appearance is improved. For example, when the texture pattern is formed with irregularities, if the depth of the recess is shallow, such as less than 70 ⁇ m, the texture pattern becomes thin and unclear, and the aesthetics are insufficient.
- the width of the fine protrusions 11 in the fine unevenness 9 is 30 ⁇ m.
- the height of the fine protrusions 11 in the fine unevenness 9 is set to 15 ⁇ m.
- the fine convex portion 11 having a width of 30 ⁇ m is “soft”, “moist”, and “smooth” like a skin material even if the convex portion 5 of the concave and convex portion 3 is not formed, that is, formed on the surface without the concave and convex portion 3. Such a pleasant tactile sensation can be enhanced extremely effectively.
- the article 1 is formed by injection molding using a thermoplastic resin. For this reason, the article 1 having the unevenness 3 on the surface can be easily manufactured.
- the unevenness shape of the article surface is such that the ratio of the area in contact with the article on the human skin is in the range of 35% to 90%
- Comfortable tactile sensations such as “soft”, “moist” and “smooth” like a skin material can be obtained.
