た。Therefore, these materials are required to have various physical properties depending on their use, but especially when used as clothing, they do not have drapability like reflective sheets used in general signs. Materials are grossly unsuitable, and in order to be suitable for clothing, they must have a certain level of flexibility, feel, visual appearance, and texture. These requirements can be met by using polyurethane or polyvinyl chloride resin, which is flexible at room temperature, as a binder for the glass beads and light reflective layer that are the constituent elements of the reflective sheet.
Although this can be achieved to some extent by using base fabrics such as various knitted fabrics and non-woven fabrics as supports, there is still a large room for improvement in terms of flexibility, texture, texture, etc. when compared with other leather-like clothing. What is more problematic is that when these retroreflective synthetic leather materials are rubbed during long-term use, they develop dark spots and spots that are thought to be due to partial destruction of the aluminum vapor-deposited film that is the internal light-reflecting layer. The appearance of wrinkled patterns (hereinafter referred to as chalk marks) is visible and significantly reduces the value of the product. The inventors of the present invention have conducted intensive research to solve the above-mentioned problems, and have found that the light-reflecting layer side of a flexible retroreflective sheet, which has been manufactured by the conventional method, is bonded with an adhesive. After bonding to the base fabric such as knitted fabric or non-woven fabric,
By subjecting the retroreflective sheet to the surface of the above-mentioned retroreflective sheet by applying pressure and stretching in a compactor (CompactOr), fine crepe-like wrinkles are added to the surface of the above-mentioned retroreflective sheet, which are independent from the base fabric structure, and the inside of the sheet is It has been found that by imparting uniform and fine cracks to the light-reflecting layer between the glass beads, it is possible to obtain an extremely excellent retroreflective synthetic leather-like material that does not produce the aforementioned check marks.

Although any of these compactors are effective in the present invention, the most preferable one is a cam-fit processing machine (Japanese Patent Publication No. 421
3419).

ることより当を得たものと思推できる。The camfit processing machine is characterized by the fact that it greatly increases the change in elasticity of the rubber surface by actively pressurizing and compressing the rubber blanket, so it is widely used for processing various knitted fabrics to give them elasticity, texture, and shrink-proofing. However, it is also particularly effective in the present invention. The first feature of the retroreflective synthetic leather-like product processed according to the present invention is that it can completely prevent the occurrence of yellow marks due to rubbing, which has been a problem in the past, due to long-term use. Although it is not yet clear why this cheese mark is generated due to rubbing, it is certain that the aluminum vapor deposited film as an internal light reflecting layer is involved, and the aluminum vapor deposition between the glass beads is more important than behind the glass beads. It is inferred that the aluminum light-reflecting layer is partially destroyed as a result of being rubbed, resulting in partially darkened stains and mottled wrinkles, or what is visually recognized as a chiyork mark, when viewed from the surface. be done. One of the reasons why the present invention is able to prevent the occurrence of these crack marks is that the aluminum vapor deposited film between the glass beads is almost uniformly stretched and destroyed by a series of stretching processes in the compactor, and as a result, the crack marks no longer occur no matter how much it is rubbed. It is thought that it occurs and disappears. This means that when you actually observe a product processed by a compactor under a microscope, you will see that there are microscopic cracks in the aluminum light-reflecting layer between the glass beads along the direction of the wrinkles. I think this is more accurate.

である。Another possible reason is that the expansion and contraction process by the compactor imparts minute crepe-like wrinkles to the surface, which diffuses the reflected light and makes it no longer visible as a clear checkmark. However, even in cases where these minute crepe-like wrinkles have almost completely disappeared due to long-term changes after processing, it is not considered to be an essentially important factor, since the occurrence of chiro-yoke marks is not observed. The second feature of the present invention is that the surface form of retroreflective synthetic leather is generally smooth and glossy before processing, and by applying stretching processing, it becomes As a result of being provided with minute crepe-like wrinkles, it is possible to impart texture improvement effects such as a matting effect and touch that are suitable for a synthetic leather-like material, as well as further flexibility and drapability.

Furthermore, the measured values of reflected brightness after processing are shown in the following table and satisfy the level 2 standard specified in JlSZ-9117. Example 3 For a product similar to that used in Example 2, one side is 2.0
