DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tatami mat using phosphorescent rushes.

[0002]

2. Description of the Related Art Imitation rush here means not only those having the appearance of natural rush but also all that can be woven like natural rush and used for tatami mats and the like.

[0003] Although the number of tatami rooms has recently decreased, they are indispensable for Japanese houses, and at least one room is often a Japanese-style room. In addition, the number of places where tatami is laid in a part of the flooring room even without a Japanese-style room is increasing.

[0004] In addition to ordinary houses, inns are naturally tatami rooms, and in each of the large halls and rooms, a larger number of tatami mats are used.

[0005]

The tatami room has an emotional feeling by itself, and is especially calm for the elderly. However, it is while the tatami is visible in the light, and is meaningless in the dark. Recently, securing and displaying an evacuation route at the time of an emergency has become a serious problem even at an inn or the like. Therefore, it has been practiced to provide a nightlight or a flashlight.

However, in the event of a power outage due to a disaster or the like, the nightlight itself is destroyed or is useless if it does not turn on, and the location of the flashlight is unknown or it cannot be reached in the dark. Occurs.

[0007]

In view of the above situation, the present inventor has completed the tatami table of the present invention as a result of intensive studies, and the feature of the present invention is that it is made of a thermoplastic resin having a phosphorescent pigment. This is in using imitation rush.

[0008] Here, the luminous pigment refers to a substance which emits light for a certain time when irradiated with light for a certain time. It is commercially available and does not need to be special. However, it is needless to say that those having a long light emission time are preferable.

[0009] The imitation rush made of a thermoplastic resin is an imitation rush made of a thermoplastic resin as a main raw material, and its production method is not limited. For example, a simple rod or pipe, a foamed one, a tape wound spirally, and a tape described later irregularly converged may be used. Although any thermoplastic resin may be used, polyethylene, polypropylene, polycarbonate and the like are suitable and may be mixed. Additives such as a weathering agent, a pigment, a matting agent, and an ultraviolet absorber may be added.

The addition of the luminous pigment to the rush may not be limited to the whole but may be partial. Further, in the case of manufacturing from a tape-shaped body, the tape may be partially added to the tape, or a mixed tape of an added tape and a tape not added may be used.

The method of adding the luminous pigment to the imitation rush is not particularly limited. However, the following method is preferred.
The first method is to apply a luminous pigment to the surface of the imitation rush. This can be done by diluting with a solvent or applying a suspension when the phosphorescent pigment is a powder or a substance having a high viscosity. The method of application may be any method such as roller or brush coating or dipping in a liquid. This coating method is efficient because the phosphorescent pigment mainly adheres to the surface of the rush.

The following is a method of mixing a luminous pigment with a raw material resin. This is to make the resin have a low viscosity and knead it therein. In this case, there is almost no difference from the step before mixing the luminous pigment, and it is very simple only by adding one more substance. In addition, since the pigment does not adhere to the surface, the pigment does not peel off, and it is considered that the use period of the rush is effective.

Next, a unique method (embracing method) used for the method of irregularly converging the tape will be described. According to this method, a tape-shaped body made of a thermoplastic resin stretched in a longitudinal direction is passed through a heating member forming a narrow gap, thereby irregularly converging and forming, and forming a fusion coating on the surface. Things. This is made of plastic, so that mites and molds do not propagate, and the so-called PP flower mat (mat made of woven plastic tubular body) has no water absorption and feels sticky,
It also eliminates the disadvantage that the texture is completely different from natural products.

When the irregular convergence is made, the luminous pigment is embraced in the tape-shaped body is the embrace system. This can be a liquid, but the powder itself is preferred. At the time of convergence (after being embraced), it passes through the heating member, so that the tape-like body softens there and adheres the powder. Therefore, a special adhesive or the like is unnecessary (may be used).

A method of manufacturing an irregular convergence type rush will be described. Stretching may be performed by a usual method, and the magnification is 2 to 2.
It is about 7 times.

The tape-shaped body may be manufactured in any manner. However, it is preferable to use a tubular body formed by inflation processing, which is folded as it is, and cut into an appropriate width for use. . A plurality of such tapes having an appropriate width are combined and passed through a heating unit to form one imitation rush. The thickness of the tape is about 0.005 to 0.05 mm, and the cutting width is several mm to about 20 to 50 mm.

The physical properties of the tape are fundamentally different depending on the type of the resin of the tape itself, for example, polypropylene and polyethylene, the degree of polymerization, and the like. Further, it differs depending on the type of the additive to be mixed therein. Further, even if such materials are exactly the same, physical properties differ depending on the thickness of the tape-shaped body and the width of slitting.

Although not necessary, the tape-shaped body may be provided with a large number of uneven wrinkles. The uneven wrinkles are wrinkles like waves that exist parallel to the longitudinal direction of the tape-shaped body, and do not need to be regular. Such wrinkles enable the imitation rush to absorb so-called stiffness and water and the like during the so-called strain, so that water absorption can be imparted.

The term "narrow space" means that the space is narrower than a state in which the tape is simply converged, and is usually about 1.0 to 1.5 mm. This value is determined by the diameter of the finished imitation rush, and is about 1 mm in the case of producing a product close to a natural rush.

The heating member may be one in which the narrow space itself is electrically heated like a heater, or a heating member may be present around the narrow space.

The term "irregular convergence" means that the tape-shaped body is not regularly folded or rolled up, but is randomly wrinkled to form a cylindrical body having the tape-shaped body inside. In this way, the tape-shaped body is made to converge irregularly, and it becomes like a natural product.

Steps other than the above essential steps may be added or other control equipment may be used. Further, the above steps may be performed in a single step, or may be performed in two steps or the like. That is, it is a method of winding and storing once at an intermediate stage, and introducing the stored product to the next step.

Examples of the steps other than the above essential steps include:
There are a cooling step and a heating step after convergence. The cooling step is usually air cooling, in which only cooling air is sent, but may be water cooling. Alternatively, a method of simply leaving it alone may be used. The next heating step is 80-100 ° C.
Heating is good, and methods such as passing through hot water or sprinkling hot water are suitable. Of course, you may heat with steam.

Naturally, even if the rush is manufactured by the irregular convergence method, the luminous pigment may be added by a method other than the embracing method. For example, a luminous pigment is applied to the surface of the completed rush, or a luminous pigment is mixed with the raw resin.

Further, the above methods may be implemented together. For example, the pigment may be mixed in the raw material, but the pigment may be added to the gap between the tapes. Further, it may be applied to the surface. In short, any method may be used.

The above described rush is woven into a tatami mat, but the weaving method at this time is free. It may be a regular tatami weave or a completely new weave. Further, the whole tatami mat may be woven with a rush having a phosphorescent pigment, or such rush may be used partially. Furthermore, when partially used, it may be woven in a pattern or a symbol.
