Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a racing suit worn by a driver such as F1.

[0002]

2. Description of the Related Art FIA-approved racing suits are
It is required to have flame retardancy that enables escape from the flame when a fire occurs in an accident.
Must pass the test prescribed in 40. Conventionally,
As a racing suit that has passed such standards,
It is said that the one in which the fiber itself has a three-layer structure of the aromatic polyamide fiber woven fabric having excellent flame retardancy has the highest safety.

However, although this racing suit is the best in terms of safety, it has been pointed out that the woven fabric itself is very hard, which makes it uncomfortable to wear, hard to move, and poor in mobility.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to provide a racing suit which uses an aromatic polyamide fiber excellent in flame retardancy, yet is flexible and easy to move and excellent in comfort. To do.

[0005]

In a racing suit of the present invention which achieves the above object, the suit fabric is composed of a knitted fabric of aromatic polyamide fiber filament yarn having at least a two-layer structure, and an adhesive is used between the knitted fabrics. It is characterized in that it is partially bonded linearly. Although the racing suit of the present invention uses the aromatic polyamide fiber filament yarn as described above, the suit fabric is composed of a highly stretchable knitted fabric, so that it is flexible and easy to move, and firefighting clothing excellent in motility and comfort is provided. Can be Further, since the knitted fabric is bulkier than the woven fabric, the two-layered structure can have a performance capable of passing the standard of ISO 6940, unlike the woven fabric, which does not have the three-layered structure.

Since the knitted fabric of the aromatic polyamide fiber filament yarn has a characteristic of being prone to curling and twisting, it is difficult to stabilize the form of the suit fabric and to make it difficult to sew it if two or more layers are left as it is. Such curls and twists can be fixed in shape by heat setting if they are thermoplastic fibers, but since aromatic polyamide fibers are not thermoplastic, they cannot be stabilized by means of such heat setting. Can not. The present invention solves such a problem of curl and twist by partially adhering the knitted fabrics linearly. That is, by providing a linear adhesive portion, twists between the knitted fabrics are canceled out to stabilize the form in the case of a structure having two or more layers.

[0007]

The present invention will be described in detail below with reference to the embodiments shown in the drawings. FIG. 1 shows a racing suit according to an embodiment of the present invention. This racing suit S is constructed in one piece, and the suit fabric is constructed of a stretchable knitted fabric 1 knitted from aromatic polyamide fiber filament yarn. As shown in FIG. 2, this knitted fabric 1 is composed of two layers of knitted fabrics 2 and 3, and the two layers of knitted fabrics are partially bonded to each other by a bonding portion 4 in which a linear adhesive is applied.

Since the suit fabric is composed of the elastic knitted fabric in this way, it is possible to flexibly and easily wear the suit,
The race can be given a special advantage. Further, since the knitted fabric of the aromatic polyamide fiber filament yarn has a property of causing curling and twisting, a simple two-layer structure is
Although it will disturb the form of the suit fabric, the knitted fabrics 2 and 3 are twisted with each other by providing the linear adhesive portion 4 between the two layers of fabrics 2 and 3 as described above. It becomes possible to restrain each other and stabilize the form.

The adhesive portion 4 for preventing such curling and twisting is applied in a linear shape and should not be adhered in a planar shape. The planar adhesion reduces the original stretchability of the knitted fabric and reduces the characteristics of the present invention that make it flexible and easy to move. A plurality of the linear adhesive portions 4 may be arranged on the upper garment portion or the lower garment portion at an appropriate pitch. In addition, as the linear direction, in addition to those arranged vertically as in the racing suit S shown in FIG. 1,
You may arrange | position in a horizontal direction or a diagonal direction. Alternatively, linear adhesive portions having different directions may be arranged so as to intersect with each other.

In the present invention, the suit fabric is composed of a knitted fabric having at least two layers, but may have three or more layers. Even when it is composed of three layers or more, since it is composed of a knitted fabric, sufficient flexibility can be secured. In the present invention, as the type of the aromatic polyamide fiber filament yarn constituting the knitted fabric having at least a two-layer structure, it is preferable to use a meta-aromatic polyamide fiber filament yarn excellent in heat resistance for the outer layer knitted fabric. . Also, the same meta-aromatic polyamide fiber filament yarn can be used for the knitted fabric of the inner layer.

However, it is more preferable to use para-aromatic polyamide fiber filament yarn, which is more excellent in strength than meta-aromatic polyamide fiber filament yarn, for the inner layer knitted fabric, or meta-aromatic polyamide fiber filament. A mixed fiber of the yarn and the para-aromatic polyamide fiber filament yarn may be used or a knitted fabric may be formed by interlacing.
By using such an aromatic polyamide fiber filament yarn for the knitted fabric on the inner layer side, it is possible to obtain a racing suit that is able to pass the ISO 6940 standard even if it has only two layers and is flexible and easy to move. it can.

[0012]

As described above, in the racing suit of the present invention, since the suit fabric is composed of the knitted fabric of the aromatic polyamide fiber filament yarn, the performance that is flexible and easy to move due to the high elasticity of the knitted fabric itself. Can be Further, since at least two layers of the knitted fabrics are partially bonded in a linear manner, curls and twists between the knitted fabrics can be canceled out, and a racing suit having a stable form can be obtained.
