Description

[Detailed Description of the Invention] [Industrial field of application] The present invention adds characteristics such as flame retardancy, deodorant properties, antibacterial properties, antistatic properties, and the like to bond the constituent fibers to each other. The present invention relates to a skin material whose back surface is coated with a backing agent.

[Conventional technology]

Although skin materials are used in various applications, for example, those used as seat skins are required to have flame retardancy. In order to impart these characteristics, conventionally, a backing agent in which a resin or latex and an additive according to the required characteristics are mixed is applied to the entire back surface of the cloth.

When a backing agent containing a resin was applied, the resin content was solidified to form a film, thereby fixing the constituent fibers and threads in the fabric, and making the skin material feel rough and hard. Moreover, when a process for bending a part of the skin material was performed, wrinkles were sometimes formed around the bent portion.

When latex was used as the backing agent, the stretchability of the skin material was restricted by the latex, so the formability of the skin material was not sufficient.

As measures against these problems, methods such as using a flexible urethane resin and making the coating amount of the backing agent extremely small have been taken. However, in the case of the former, there is a problem that the cost is high and sufficient flexibility cannot be obtained, and in the case of the latter, properties such as flame retardancy cannot be sufficiently imparted.

[Problems to be Solved by the Invention] In view of the above-mentioned conventional problems, an object of the present invention is to provide a skin material having improved flexibility without impairing the required characteristics as compared with the conventional skin material. Is to provide.

[Means for solving problems]

The object of the present invention is to provide a backing material composed of a resin or latex and an additive on the back surface of a fabric, and the backing agent-coated part and the non-coated part form a sea-island structure. , It can be achieved by uniformly spreading the part coated with the backing agent.

[Action]

In the skin material of the present invention, the portion not coated with the backing agent is evenly spread, and this portion is relatively flexible because the fibers constituting the cloth can move relative to each other.
Therefore, when a force for bending the skin material of the present invention is applied, the portion not coated with the backing agent easily bends, so that the flexibility of the entire skin material is improved.

〔effect〕

The skin material of the present invention is less affected by the backing agent, has excellent flexibility because it is soft, and does not wrinkle even if it is bent.

In addition, even if it has excellent properties such as flame retardancy, it cannot be used because it is a backing agent that causes the texture of the skin material to become coarse and hard when it is backed, or it is cheap but the texture becomes coarse and hard. Backing agent can be used,
It is possible to provide a higher performance or cheaper skin material.

〔Example〕

1 to 2 show a first embodiment according to the present invention, wherein FIG. 1 is a plan view of the back surface of the skin material, and FIG. 2 is a partially enlarged view of FIG.

In FIG. 1, 1 is a skin material, 2 is a non-backing cloth portion, 3 is a backing portion coated with a backing agent, and in FIG. 2, x is the center distance of the backing portion and r is the backing. Indicates the radius of the part.

As shown in FIG. 1, in the first embodiment, a polyester cloth is coated with a backing agent composed of an acrylic ester resin and antimony trioxide in a polka dot pattern. The backing portions 3 are regularly arranged so that the backing agent is applied substantially uniformly. That is, as shown in FIG. 2, six backing portions are arranged so as to surround an arbitrary backing portion as a center, and further, the center-to-center distance x of each backing portion is made equal. When the cloth is a woven fabric, the backing portions 3 are arranged according to the directions of the constituent yarns (directions a and b in FIG. 1), and the constituent yarns to which the backing agent is not applied are eliminated so that the backing portions 3 do not overlap. In order to
The size and arrangement of the backing portion 3 are set so that x and r satisfy the following equation.

2r <x <4.3 · ^1/2 · r / 3 In this embodiment, since the unbacked fabric portion 2 is continuous and evenly spreads, the flexibility is reduced by applying the backing agent. And a decrease in elongation can be suppressed.

Although the shape of the backing portion 3 is circular, it is not limited to this and may be polygonal or irregular as long as the backing has a size and an arrangement that allows the backing to be substantially even.

FIG. 3 shows a second embodiment according to the present invention.

In FIG. 3, reference numeral 11 is a skin material, 22 is a non-backed cloth portion, and 33 is a backing portion coated with a backing agent.

In this embodiment, since the backing portion 33 has a lattice shape, the fabric portion 22 is not continuous and is not as flexible as the first embodiment, but the effect of preventing the fraying of the constituent fibers is the same as that of the first embodiment. Is better. The materials of the cloth and the backing agent were the same as those in the first embodiment.

When the cloth is a woven fabric, it is desirable to form the backing portion 33 in the bias direction with respect to the direction of the constituent yarns so that the amount of the backing agent applied to the constituent yarns can be leveled.

4 to 5 show a third embodiment according to the present invention. FIG. 4 is a plan view of the back surface of the skin material, and FIG. 5 is a sectional view taken along the line AA of FIG.

4 to 5, 4 is a cloth, 5 is a first backing layer, and 6 is a second backing layer.

In this embodiment, polyethylene is applied to the entire back surface of the polypropylene cloth 4 to form the first backing layer 5,
A second backing layer 6 is provided by applying a backing agent composed of an acrylic ester resin and a chlorine compound on it in a polka dot pattern. However, when the compatibility between the fabric and the backing agent is poor, or when the backing agent is used as a skin material, It can be applied when two kinds of backing agents cannot be mixed and characteristics of one kind are required.

For example, since polypropylene fibers are attacked by chlorine compounds, it was not possible to combine them, but by interposing polyethylene between the polypropylene cloth and the chlorine compound-based backing agent as in this example, the above combination was achieved. Will be possible.

Further, in the past, when two kinds of backing agents were coated respectively, the backing agent layer became thick and the texture of the skin material became even rougher. However, by adopting the configuration of this embodiment, two types of characteristics can be added while maintaining the almost same texture as the conventional one-time backing.

Furthermore, even when the cloth is a woven cloth, the strength of the cloth and the prevention of the fraying of the fibers are guaranteed by the first backing layer,
The second backing layer is not restricted in the direction of the constituent fibers, and a free pattern can be selected.
