In the 1800s, when the development of the railway network made it easy for the general public to go to the beach area, it was made of materials such as surge and flannel alpaca so that the skin could not be seen even if it got wet. Wearing top-and-bottom clothes with elbow-length sleeves and pants that cover the knees (this is the etymology of a swimming suit, with the word "suit" meaning "up-and-down"). In the 1900s, sleeveless knitted swimsuits with deep chest were introduced, and after that, the design changed to have large exposed skin.

Famous under the name of "Underwater Ballerina" in 1907Annette Kellerman(A swimmer from Australiaactress, The first woman who tried to swim across the English Channel, visited the United States, a one-piece swimsuit with exposed neck and limbs that is easier to move than the previous swimsuit that hinders underwater movement. There was a case in which he was publicly arrested for indecent assault. Not only did the one-piece swimsuit show off the lines of the body, it showed a bold and active new form of swimwear to society, but at the time when the movement to expand women's rights flourished, "Women It was accepted as an appeal of "the right to wear a one-piece swimsuit".

Around 1920, it was called a scooped neck in the sense of a quilted swimsuit with a short skirt, or a half-moon deep chest (a chest scooped with a scoop) that was sewn together without the skirt. ) And "Tank suit (tank suit tank refers to an aquarium, indoor pool)" with wide shoulder straps cut from the body became popular. Active and functional tank suit designJapanso"School swimwearIt is inherited by the school swimsuit known as ".

By a French designer, in 1946ビ キ ニA two-piece swimsuit with a large exposed skin is named. It is said that the name "bikini" is derived from the combination of the stimulating impression of a swimsuit and the shocking impression of the atomic bomb test at Bikini Atoll at that time, and the traditional clothing of the natives around Bikini Island. ing. Also in 1964, the American bikini by Rudy GarnlickbraIs omittedtoplessWas announced.

In the latter half of the 1970s, he increased the trim around his legs.High leg・"Cut" has been introduced, and stretch materials with high elasticity and chlorine resistance (synthetic fibers such as nylon and polyurethane) have become popular.Los Angeles OlympicsSince 1984, the number of people other than swimmers who enjoy swimming as part of their health promotion at fitness clubs and swimming clubs has increased. The market for swimsuits and swimwear with a figure correction function designed based on them has expanded.

It is well-established that different swimsuits with different designs can be used depending on the location (coast, pool, resort, etc.) and purpose (race, swimming as fitness, swimming, swimming and swimming, wearing as fashion, fascinating fun, etc.).

Classification by purpose of use

For exercise

CompetitionFitnessSwimwear used for. You need to be able to move your body, not to come off easily, and to reduce water resistance (especially in swimming).SwimmingFor swimwear,School swimwear,Such. past,SwimmingAthletes tend to increase their skin's exposure to reduce the resistance of water by the swimwear itself,Boys TheBusiness BagMold,woman TheHigh legThe mold was common.the 2000sFrom around that time, when the resistance of the swimsuit surface became lower than the resistance of the skin by devising the material and surface pattern of the swimsuit, things like wrapping the whole body except the neck, wrists or arms, ankles began to spread. , I often use long swimsuits.OlympicNew materials and high-tech materials are actively introduced into swimwear for competitions.Life saverIn the same way, things like wrapping around the whole body are beginning to spread, but many of these things place importance on avoiding danger and maintaining body temperature.

  • Swimminguse -Basically what is called "for swimming" is certified by the Swimming Federation. The degree of adhesion and pressure is very high, and the elasticity is low compared to fitness applications. It has less resistance and prevents unnecessary blurring of the body, but durability is not important and deterioration is severe. In addition, men's swimwear is supposed to be worn on the waist except for the same one-piece type as women's. This is because if it is adjusted to the abdomen, the adhesiveness is impaired due to the inflow direction of water, the difference in diameter between the buttocks and the abdomen, and the change in the diameter of the abdomen due to the operation, and the resistance increases. For this reason, the buttocks (glutes) may be slightly exposed, but this is inevitable because the swimwear to be worn is a ready-made item. However, when the buttocks (glutes) are largely exposed, a large amount of water enters the gap between the glutes and the swimsuit, resulting in resistance. In addition, wearing high-grade swimwear that is extremely small for competition tends to limit the movements of the thighs and buttocks. This situation is unsuitable for competition and it can be said that the size of the swimsuit is not suitable. For both men and women, wearing a small size too much is not only the two disadvantages, but also because the material is too stretched and the performance as intended for the design cannot be exerted, so it is necessary to be careful when selecting the size.
  • Fitnessuse - SwimmingIt is not tight compared to the one for use, and it is for enjoying underwater exercise, and because of the high degree of freedom of the material, the design is high. Most of the products are made of soft and highly stretchable fabric (double layers depending on the part/product) to make it easy to move and comfortable to wear. As for the shapeSwimmingMany are suitable forwomanThere is also a separate type for use.
  • water polouse -Due to competition characteristics, two slippery materials are layered and surface treatment is applied to make it difficult to grasp and tear. Some of the fabrics in the buttocks have some room to accommodate large movements of the water polo.

Designs, colors, patterns, etc. are very different, but since light-colored fabrics such as white will show through when they get wet with water (except for "to show" as described later) It is rarely used. However, from around the 2000s, new materials called "transparent white" have appeared.

The form is almost the same for both men and women, with relatively long sleeves or short sleeves. In order to improve the body's protective performance, it is often thicker and more clogged than other swimwear. Since it is slightly different from conventional swimwear in terms of shape and material, it tends to be sold separately from swimwear as a product, but it is practically the swimwear itself in terms of usage and basic structure.

This was once learned by having modified the swimsuit as a costume for a match, and newcomers often used the modified swimsuit after the latter half of the 1990s.

  • Wheel-type hook of wisdom-There is a small weight at the tip of the ring that has slightly different shapes on the left and right, and the right weight is passed through the left wheel. There is no procedure to press and fix it with your finger, but the elastic force of the string pulls it into a straight line, so it is fixed without a gap. Since metal is always used in terms of strength, it has the feature that the shape of the ring and the weight part can be decorated. On the contrary, it is limited to strings.

Overview of swimsuits

Since the 1970s, swimsuits have been constantly improving materials and reviewing designs, and have contributed to improving records. In such circumstances, competition for sports equipment manufacturers involved in the production and sale of swimwear has developed, and in some cases this has led to the reorganization of the industry.

International Swimming Federation(Fina)2007,Beijing OlympicsTherefore, it is prohibited to apply special processing (for speeding up) to the swimsuit surface.” As a result, each manufacturer has been forced to discontinue the production of swimsuits with scales, protrusions, and stripes. In order to make this rule known well, in some countries the new rules may be implemented ahead of schedule in some cases. Meanwhile, SPEEDO developed "Laser racer",2008, Became a big deal in the world of swimming.

20097/24In the International Swimming Federation20101/1Therefore, a new regulation that bans swimwear that uses non-permeable materials such as rubber film and polyurethane film is completely fixed, and the material is limited to fabric. The range that swimsuits can cover is limited from the navel to the knees for boys and from the knees to the knees for women, and the restrictions on material thickness and buoyancy have been strengthened.[5].

Bar code system

To secure them further,Two-dimensional codeIntroduced a swimsuit management system that uses a swimsuit, and completely forbidden wearing swimwear without a Fina standard approved barcode on the hips at official competitions. After one year, it has been fully implemented since April 1 including Japan.[6][Broken link].

The bar code records data such as the manufacturer, model, and approval time, as well as the individual approval number. In general, the competition operates as follows. In principle, this inspection should be used in combination with visual confirmation. For visual confirmation, check whether the regulations on the size of trademarks etc. are observed,You must wear the same swimwear from the same qualifying round to the finalIt is done to understand whether the Fina rule of "is adhered to."

  1. First, in qualifying, check whether there is a bar code on the buttocks at the time of convocation, and at the same time scan the data to see if it matches the data of the approved swimsuit registered on the server of the administration headquarters. If the barcode does not match the server data, you will be disqualified for violating the swimsuit rules. This is intended to support future swimsuit rule revisions. Save the scanned data by associating it with the player's personal information[7].
  2. The method is the same after the semi-final, but a check is also made to see if it matches the data that has been newly read. This is also to confirm whether or not the “same swimsuit of the same event” is violated.
  3. Initially, bar code scanning may be difficult to implement except in large competitions, in which case it may only be a visual confirmation.

It is quite possible that the approval bar code is peeled off due to deterioration. Although there is a remedy available, it is not desirable to continue using the swimsuit with the bar code removed for competition, and the reality is that it can only be removed for regular practice.

As of 2013 New Year's Day, there were no cases in which there was a bar code and the approval was withdrawn because there were no major revisions to the swimwear rules after the bar code was introduced.


In the latter half of the 20th century, as a material for swimwearNylon : PolyurethaneWoven fabrics using yarns blended in a ratio of 4:1 were common. Polyurethane is mixed because nylon has poor plasticity.[8]However, this was to compensate for this, but it became the source of the drawback of swimwear that it was easily deteriorated by the chemical properties of urethane.

In the latter half of the 1980s, nylon was replaced with nylon to solve this problem and thin the thread.polyesterThe number of cases in which the yarn based on is the basis of the cloth has increased, and later became the mainstream of swimwear materials for competition. However, after the Fina swimwear regulations were revised in the 2010s, nylon-based cloths are being used again for top swimmers in order to obtain a tightening effect.

The polyurethane thread used in swimwear isDuPontDeveloped byspandex(Product name: “Lycra”) is widely used, and “Invista”, a subsidiary sold by DuPont to US family-owned company “Cork Industries”, is in charge of the business. In Japan with INVISTATorayIs supplied by a joint venture company.
