A mode for carrying out the present invention will be described with reference to the drawings.
(Structure of interior moquette according to this embodiment)

The structure of the interior moquette (hereinafter, simply referred to as “moquette”) 1 according to the present embodiment will be described with reference to FIGS. 1 to 4. 1 and 2 are views showing an application example of the moquette 1, and FIG. 3 shows the structure of the moquette 1 and explains the state of the moquette 1 when a liquid 22 such as food or drink or water spills on the surface. FIG. 4 is a diagram illustrating a manufacturing process of the moquette 1.

As shown in FIG. 1, the moquette 1 is a woven fabric used as a skin material for a seat surface 16 included in a seat 14 installed in a railroad vehicle, an aircraft, an automobile, or the like. As shown in FIG. 2, the seat 14 has a seat portion that is a portion that comes into contact with the buttocks when a person sits, and in the seat portion, a seat surface 16 formed of moquette 1 is arranged on the outer surface. To. Then, a filling material 18 such as urethane is arranged inside the moquette 1, and a frame and a spring 20 are arranged below the filling material 18. That is, in the seat 14, the seat surface 16 formed by the moquette 1 is a portion that comes into direct contact with the person sitting on the seat 14.

As shown in FIG. 3, the moquette 1 has a base cloth 2 and a pile portion 4. In addition, the moquette 1 may have a backing layer on the back surface for the purpose of preventing hair loss and the like.

The base cloth 2 may be, for example, a plain weave fiber using ester rayon, and may be the same as the base cloth which is a component of a conventionally known interior moquette. The base cloth 2 is a concept including a ground structure made of warp and weft.

The pile portion 4 is a portion formed on the base cloth 2 by using the pile yarn 6, is located on the surface of the moquette 1, and is a portion that gives a soft texture. Here, as the pile yarn 6, the synthetic fiber yarn 8 is used in one portion (region) of the pile portion 4 (moquette 1), and the liquid holding performance yarn 12 is used in the other portion (region).

Liquid retention performance The thread 12 has a function of permeating and retaining liquid 22 such as food and drink, water, etc., so that the "color of the part where the liquid 22 permeates and is held" is different from the "color of other parts". Make it visible to. Liquid retention performance In the yarn 12, the refractive index of light differs between the portion where the liquid 22 is retained and the other portions, and in appearance, the colors appear different in these portions.

Here, the wool yarn, which is an example of the liquid retention performance yarn 12 using natural fibers, has a cortex (skin quality part) inside each of the wool yarns, so that the liquid 22 such as water is applied to the cortex part. It has the property of penetrating into and retaining it inside. In the wool yarn, the refractive index of light differs between the portion where the liquid 22 is held in the cortex and the other portions, and the colors appear to be different in these portions in appearance. In wool yarn, a hydrophobic scale (skin) is arranged on the outside, while a hydrophilic cortex (skin quality) is arranged so as to cover the inside, and the liquid 22 is repelled by the initial scale. It is watered, but gradually soaks into the cortex and is retained by the wool yarn.

Further, since the fiber itself is crimped, the crimped polyester yarn, which is an example of the liquid holding performance yarn 12 using synthetic fibers, holds the liquid 22 such as water on the surface (the crimped portion). It has the property of causing. Further, in the crimped polyester yarn, the refractive index of light is different between the portion where the liquid 22 is held and the other portions, and the colors appear to be different in these portions in appearance. The liquid retention performance yarn 12 may be a synthetic fiber yarn other than the polyester yarn, which has been subjected to the crimping processing based on the same principle as the crimping polyester yarn.

Therefore, in the moquette 1, when the liquid 22 on the moquette 1 is infiltrated and held in the portion of the liquid retention performance thread 12, the "color of the portion in which the liquid 22 is infiltrated and retained" in the pile portion 4 is "another portion". By utilizing a visual phenomenon that looks different from the "color", the user of the seat 14 can easily visually confirm whether or not the moquette 1 is wet with the liquid 22.

For example, the synthetic fiber yarn 8 is used on the moquette 1 at a place where the outline of the pattern is desired to be clearly shown and a place where the color development property is desired to be improved. For example, the liquid holding performance yarn 12 is used in a place having a large area or the like. Further, the liquid holding performance thread 12 is arranged in a specific pattern (pattern) regardless of the color pattern of the moquette 1, so that a specific pattern is expressed in a wet place and the wet part can be visually recognized. It can also be.

Each of the "part formed by the synthetic fiber yarn 8" and the "part formed by the liquid holding performance yarn 12" in the pile portion 4 has the intention of conspicuously changing the color due to water immersion on the seat surface 16 (moquette 1). Will be arranged as appropriate. This is because the synthetic fiber yarn 8 is used in the pile portion 4 on the surface of the moquette 1 where the pattern change is relatively large, and the liquid holding performance yarn 12 is used in the portion where the pattern change is relatively small. You can also catch it. This is a suitable condition for the moquette 1 to exhibit a function that allows a person to visually detect whether or not the seat surface 16 is in a wet state.

In the pile portion 4 on the surface of the moquette 1, the liquid holding performance yarn 12 is used for the portion where it is desired to indicate that it is wet (flooded), and the synthetic fiber yarn 8 is used for the other portion. It is suitable for exerting in 1.
The synthetic fiber thread 8 is a synthetic fiber thread that has not been subjected to a crimping process, and is preferably a polyester thread (100% polyester thread).

In general, since the liquid holding performance yarn 12 is relatively expensive, the amount of the liquid holding performance yarn 12 forming the pile yarn 6 is suppressed within the range in which the moquette 1 can exert the above function, so that the moquette can be used. The manufacturing cost of 1 can be suppressed, and the moquette 1 can be manufactured at a reasonable manufacturing cost.

The pile portion 4 may be water-repellent with fluorine, as in the case of general moquette fabric used as a skin material for seats of railway vehicles, aircraft, automobiles and the like. By doing so, the liquid 22 can be wiped off immediately after the liquid 22 such as food and drink spills on the seat surface 16 (moquette 1).

As shown in FIG. 4, in the moquette 1, the upper base cloth 2 and the lower base cloth 2'are woven into the upper and lower base cloths 2 and 2'in the same manner as in the conventionally known manufacturing method of the moquette, and the pile yarn 6 is used. It is woven as a double woven fabric connected by. Then, after the moquette 1 is woven, the pile yarn 6 connected between the upper base cloth 2 and the lower base cloth 2'is center-cut by a cutting means such as a cutter, and two upper and lower double sheets are manufactured at the same time. Will be done.
(How to use the interior moquette according to this embodiment)

A method of using the moquette 1 will be described with reference to FIGS. 1 to 3. As shown in FIGS. 1 and 2, the moquette 1 can be used as a skin material for seats of railway vehicles, aircraft, automobiles and the like. At that time, since the person who intends to take a seat in the seat 14 sits on the moquette 1 stretched on the seat surface 16 of the seat 14, the buttocks of the person and the moquette 1 come into direct contact with each other.

Therefore, when the liquid 22 such as food and drink spills on the seat surface 16 and the seat surface 16 is wet, the person who intends to take a seat in the seat 14 "is a portion where the liquid 22 is permeated and held in the pile portion 4". It is possible to detect that the seat surface 16 is wet by utilizing a visual phenomenon in which the "color" looks different from the "color of other parts". A person who intends to take a seat in the seat 14 may take a seat after removing the liquid 22 from the seat surface 16 or may stop taking a seat.

On the other hand, a person who intends to take a seat in the seat 14 sits in the seat 14 according to a general seat usage method when the seat surface 16 is not wet, that is, when the color change in the pile portion 4 is not observed. ..

Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the specific embodiments thereof, and various modifications are made within the scope of the gist of the present invention described in the claims.・ Can be changed.
