Abstract

PROBLEM TO BE SOLVED: To provide low-fluid-resistant clothes obtained by the fluid resistance reduction technology for installing concave and convex on the surface of the clothes. SOLUTION: A concave and convex pattern is formed on the surface to clothes or a cloth 1 having a finely knitted construction with a high gauge by carrying out the embossing and heat treatment of a material for synthetic fiber clothes. The concave and convex pattern 4 is formed from a longitudinal, transverse, oblique, intermittent protruded ridge, concaved ridge, dot, dimple, scaled pattern of fishes, appearance pattern of birds, or a combination thereof. The concave and convex pattern 4 has a structure having a different fluid resistance between the front body and the back body of the clothes or between the upper part and the lower part of the clothes.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a low-resistance fluid garment, which relates to a technique for reducing fluid resistance in ultrafine synthetic fibers.

[0002]

2. Description of the Related Art Conventionally, various techniques for reducing fluid resistance on clothes have been used. In particular, synthetic fibers have been considered as clothes for swimming swimwear or various sports in which synthetic resin dots or ridges are attached or adhered to the surface of the clothes in order to reduce the fluid resistance.

[0003]

However, in a structure in which dots or ridges are stuck or adhered, the weight of the clothes becomes large and heavy, so that the knitted fabric or the woven fabric itself is organized into irregularities to make the clothes irregular. However, with a high gauge fine denier yarn material (30 to 40 gauge), the knitting structure was too fine and knitting itself was difficult. More recently, the thickness of clothes has recently been reduced by about 0.4 to 0.5 mm, so knitting itself is often difficult to produce knitting scratches and thread breaks, even in plain fabrics,
Furthermore, it was very difficult to obtain the pattern, and there was a problem that the high gauge knitting machine could not make the unevenness.

[0004] The present invention has been made in view of the above problems,
An object of the present invention is to propose a fluid resistance reduction technology for providing irregularities on the surface of a garment by applying heat treatment to a cloth itself having a fine knitting structure with a high gauge to form irregularities, and to provide a low-resistance fluid garment.

[0005]

SUMMARY OF THE INVENTION A low fluid resistance garment according to the present invention is characterized in that a synthetic fiber garment material is embossed and heat-treated to form an uneven pattern on the surface of the garment material. In other words, by embossing heat treatment on synthetic fiber garment material,
The uneven pattern is formed in a vertical, horizontal, diagonal, or row shape.

[0006] The above-mentioned concavo-convex pattern can have different fluid resistance between the front body and the rear body of the garment, or can have different fluid resistance between the upper part and the lower part of the garment. In addition, the uneven pattern is
The surface is uneven and the back side is almost smooth, the uneven pattern, ridges,
It can also be a concave stripe, a dot, a dimple or a fish scale, a bird's appearance, or a combination thereof.

In a method of forming a low-resistance fluid garment, a surface of a synthetic fiber garment material is opposed to a female mold, and a concave and convex pattern is formed on the surface of the garment material by pressing the back surface of the garment material with a stamping and heating device. The gist is to do.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The embossing process is performed while heating a desired portion of a synthetic fiber material of fine denier yarn with a high gauge of ~ 40. As shown in FIG. 1, a female mold 2 is placed on the front side of a dough material 1 and hot pressed by a hot press 3 from behind. The female mold 2 can be made of any material such as a metal plate, a synthetic resin plate or cardboard.

Depending on the female mold 2, irregular patterns, dots or dimples, or irregular patterns 4 such as pictures can be freely formed, and irregular patterns 4 such as a special fish scale pattern can also be formed. The concavo-convex pattern 4 may be formed on the cloth material 1 made of a synthetic fiber material, or may be formed after sewing clothes from the cloth material 1. The concavo-convex pattern 4 can be formed on the entire or desired portion of the garment, and as shown in FIG. 2, the concavo-convex pattern is formed in a vertical (a), horizontal (b), oblique (c) or cross-sectional form. They can be provided in a row (d).

The uneven pattern 4 has a different shape between the front body and the rear body of the garment, or the uneven pattern 4
, The fluid resistance can be configured to be different. This is also true for the top and bottom of the garment,
The configuration of the concavo-convex pattern 4 can be changed between the upper body of the clothes and the pants, so that the fluid resistance is different.

The fluid low-resistance garment having the above-described structure has a rectifying effect in the fluid with water or air due to the uneven pattern. As a result, the separation from the fluid proceeds, and the Karman vortex is reduced, so that the fluid resistance can be reduced. Therefore, the present invention is significant not only in swimwear for swimming but also in ice skating wear and cycling wear. It is also useful for means such as changing the air resistance between the front body and the back body of clothes, such as ski jumping.

The uneven pattern 4 is crushed by hot pressing, and the uneven back surface 5 pressed by the hot press machine 3 is substantially smooth, and the convex, concave, dot, dimple or fish scale pattern on the surface is obtained. Also, no bird appearance pattern, or a combination thereof, etc. appears.

In the low-resistance fluid garment having the above-described structure, the portion provided with the concavo-convex pattern 4 is crushed and looks dark, thus preventing see-through. Therefore, it not only has a function of reducing resistance to water such as rectification by the uneven pattern 4, but is also useful for preventing see-through in swimwear and the like, and is particularly useful as a women's swimsuit.

Since the uneven pattern portion 4 has a higher knitting density and a higher tension than other portions, it is necessary to tighten the chest of a swimsuit for swimming or the thigh of running pants, or a corset or leotard for women. The tightening part can be used for clothes if necessary.

[0015]

As described above, according to the fluid low-resistance garment or the method for forming a fluid low-resistance garment according to the present invention, a rugged pattern is formed on a garment made of a high-gauge synthetic fiber material. The object was achieved by processing by embossing with hot pressing. Depending on the female mold, uneven patterns, dots or dimples, or uneven patterns such as patterns can be freely configured, and it is also possible to configure uneven patterns such as special fish scales or birds appearance patterns, and thereby water. Alternatively, the present invention has a feature that the resistance to air can be reduced, and the effect obtained by implementing the present invention is extremely large.
