Conventionally, many proposals have been made for methods of imparting stamped patterns to the surface of elastic polymers using a heat embossing method. For example, Japanese Patent Publication No. 47-24662 describes a method for producing a sheet material in which the open surface of an embossing roll is heated, then pressure embossed, and peeled off at peeling points provided at a certain distance; Japanese Patent Publication No. 55-6754, Kosho 57-
23036 and Japanese Patent Publication No. 57-23037, a leather-like sheet having a porous coating layer is heated and embossed at 100 to 300°C, and the coating layer is self-adhered to the hot roll while the circumference of the hot roll is constant. It is described that after advancing a distance, peeling is performed using a peeling roll provided on a heat roll.

に剥離するものである。 In this way, the conventional method of imparting an embossed pattern to the surface of an elastic polymer is to emboss it with a heated embossing roll at high temperature and under high pressure, to make it self-adhere to the embossing roll, and then to apply it at a certain distance on the circumference of the embossed roll. A provided peeling roll forcibly peels off the paper from an embossing roll.

In the conventional method, the surface of the elastic polymer is embossed directly, so sufficient embossing cannot be achieved without using high temperature and pressure.Furthermore, it is forced to peel off after being self-adhesive to the roll and heat treated. In addition, the embossed surface of the pressed sheet becomes rough, and if peeling is not smooth, the embossed surface becomes deteriorated, such as uneven peeling resulting in horizontal steps of peeling. Further, even if the sheet is self-adhered to the roll, the sheet surface often peels off from the embossing roll surface before reaching the peeling roll. In that case, the surface of the embossed sheet will be uneven due to uneven gloss, pattern return, etc. in the areas that are in close contact with the embossing roll and the areas that are floating from the embossing roll. Further, the embossed sheet has problems such as hard texture, stiffness, and surface roughness due to heat embossing and forced peeling due to high temperature and high pressure.

The purpose of the present invention is to heat a sheet-like material having a surface composed of a polymer mainly composed of an elastic polymer, and apply pressure embossing to the surface of the polymer to faithfully imprint an embossed roll pattern, and to embossing the material. The purpose of this invention is to provide a method for producing a sheet with a good surface embossed texture that does not impair the texture of the sheet.

The sheet is brought into contact with the embossing roll by a guide roll provided in front of the heated embossing roll, and the sheet is preheated by moving along the roll at least 1/4 of the roll circumference, and then pressurized and embossed with the embossing roll. It is characterized by:

1 and 2 are side views showing one embodiment of the present invention. A pair of rolls 1 and 2 are embossing devices; 1 is an embossing roll equipped with a heating device, 2 is a back roll, and 3 is a guide roll provided in front of the embossing roll. The surface-embossed sheet S is fed through a guide roll 3 so that the polymer surface is in contact with the surface of the heated embossing roll 1, preheated between embossing poles A and B, and then heated at point B. Emboss. If the embossed sheet has low self-adhesion, it will peel off at point C after a slight heat treatment, as shown in Figure 1, but if it has high self-adhesion, it will peel off over a long distance as shown in Figure 2. Heat treatment is performed. Natural peeling occurs as the heat treatment progresses and the strain of the embossed sheet is relaxed. When the distance of the natural peeling point C is long, it is preferable for continuous production to additionally install a peeling roll 4 near the peeling point. It is also preferable that the peeling roll 4 is a variable type peeling roll that moves as the natural peeling point moves.

The embossed sheet is forcibly peeled off at a peeling point C.

時の歪が残り、カール現象を生ずる。 In the method of the present invention, the surface-embossed sheet is preheated before pressure embossing, and pressure embossing is carried out while maintaining that state, so the temperature and pressure during embossing are lower than in conventional methods. You can choose from a variety of colors, and you can also emboss a clear pattern. The heating temperature of the embossing roll is usually approx.
It is preferable that the temperature is 100 to 190°C, preferably about 120 to 180°C, the embossing pressure is about 2 to 30 kg/cm 2 in surface pressure, and the self-adhesion strength to the embossing roll is not high. For self-adhesive strength, the distance from embossing pressure point B to peeling point C is preferably 1/8 of the roll circumference.
Select a roll temperature and pressure that will cause natural separation within 1/2 turn from the circumference. If embossing is carried out at high temperatures and pressures that do not cause natural peeling, the embossing surface will not only become rough and have an unfavorable surface condition, but also the texture will become stiff and stiff, and distortion during embossing will remain. Causes curling phenomenon.

Using an embossing roll with small protrusions (depth of recesses approximately 900 microns), heating the embossing roll to a temperature of 170°C, and using the method shown in Figure 1, the sheet-like material is The colored side was brought into contact with the surface of the embossing roll and preheated for about 30 seconds, then embossed with a surface pressure of 15 kg/cm 2 to make it self-adhesive, but it was about 1/8 from the pressing point.
Spontaneous separation occurred at a circumferential distance. The obtained pressed sheet had wrinkles on the surface with a concave-convex pattern having concave portions of about 600 microns in depth, and had a very three-dimensional effect and excellent flexibility.

It is not possible to make a beautiful embossed pattern. So I raised the temperature of the embossing roll to the point where it self-adhesed, and the result was approx.
It was 198℃. However, when the sheet was embossed at an embossing roll temperature of about 198°C, uneven peeling occurred when it was peeled off from the embossing roll, and the texture became harder.

じなかつた。 Next, the above-mentioned sheet-like material is made into a second layer by using an embossing roll with a sheepskin pattern (the depth of the recesses is about 200 microns).
Using the method shown in the figure, it was brought into contact with the surface of an embossing roll heated to 170°C, preheated for about 25 seconds, and then embossed with a surface pressure of 20 kg/cm 2 to achieve self-adhesion. In this case, the point at which the sheet material peels off is approximately 1/1/2 from the pressing point.
The distance was 3 laps, and the heat treatment time during that time was about 25 seconds. Therefore, when we installed a position-variable peeling roll 4 at the natural peeling point and performed continuous operation, we found that the pattern of the embossing roll was embossed almost faithfully, and a sheet-like material with a flexible texture and no surface roughness was obtained. It was done. This embossed sheet material was dyed in a reddish color using a wince dyeing machine, dried, and rubbed, but there was almost no change in the width or length of the sheet material.

くなり、長さ方向の伸びが大きかつた。 For comparison, when a sheet material was directly fed to an embossing press point and embossed using the method shown in FIG. 3, the embossing roll temperature at which self-adhesion was obtained was approximately 190°C. Therefore, when we embossed the above sheet at an embossing roll temperature of 190°C, not only did it cause uneven peeling when it was peeled off from the embossing roll, but it also became narrower in the width direction by about 18% and had a large elongation in the length direction. .

Since the embossing of the polymer surface of the present invention is preheated on the embossing roll surface, there is almost no uneven preheating on the sheet surface, and a faithful embossed pattern can be imparted at a relatively low temperature and pressure. This prevents the hardening of the texture of the embossed sheet and enables natural peeling, which eliminates deformation of the embossed pattern, surface roughness, and generation of horizontal peeling steps, resulting in an embossed sheet with a good embossed surface. It will be done.
