Description
本発明は、例えば水着、スピードスケート用ウエア、体操用のレオタードなどのスポーツウエアや、ガードル、ボディスーツなどの補整用下着（ファンデーション）といった衣服における布帛構造および接着方法に関するものである。 The present invention relates to a fabric structure and a bonding method in clothes such as sportswear such as swimwear, speed skate wear, and leotard for gymnastics, and correction underwear (foundation) such as girdle and body suit.
各種スポーツ着、例えば特許文献１に記載されるフィットネス用水着やレース用水着は、身体に対してフィットする伸縮性のあるストレッチ生地から作られる。近年ではストレッチ性が高い様々な生地が使用されている。 Various sports clothes, for example, a fitness swimsuit and a race swimsuit described in Patent Document 1 are made of stretch fabric having elasticity that fits the body. In recent years, various fabrics with high stretchability have been used.
例えば水着を構成するストレッチ生地同士を接合する場合には超音波接着法が用いられる。ストレッチ生地同士を接合しただけでは接合部の目開きが発生してしまう虞があるので、接合部に沿う方向に対して伸縮性が比較的高く、当該方向に直交する方向（目開きが生じる方向）に対して伸縮性が比較的顕著に低いストレッチテープを接合部に接着することが一般的である。 For example, when joining stretch fabrics constituting a swimsuit, an ultrasonic bonding method is used. Since joining the stretch fabrics may cause opening of the joint, the stretchability is relatively high in the direction along the joint, and the direction perpendicular to the direction (direction in which the opening occurs). In general, a stretch tape having relatively low elasticity is bonded to the joint.
しかしながら、生地として特にストレッチ織物素材やニット素材に上記ストレッチテープを接着した場合に、当該ストレッチテープ際に大きな負荷がかかると、このストレッチテープが剥離することや当該ストレッチテープに生地の一部が引き摺られる現象（スリップ現象）が発生し、接合部分に破損が生じることがあった。このような結果、水着等の衣服が着用できなくなってしまう問題があった。 However, especially when the stretch tape is bonded to a stretch woven material or knit material as a fabric, if a large load is applied to the stretch tape, the stretch tape may peel off or a part of the fabric may be dragged onto the stretch tape. Phenomenon (slip phenomenon) occurs, and the joint may be damaged. As a result, there is a problem that clothes such as swimwear cannot be worn.
本発明はかかる事情に鑑みてなされたものであり、本発明の目的は、剥離やスリップ現象が発生する危険性を低くすることが可能な布帛構造および接着方法を提供することである。 The present invention has been made in view of such circumstances, and an object of the present invention is to provide a fabric structure and a bonding method capable of reducing the risk of occurrence of peeling and slipping.
本発明に係る布帛構造は、第１布帛の一端部と第２布帛の一端部とが接合された接合布帛の布帛構造であって、第１布帛と第２布帛との接合部を覆うように接着される帯状シートを備え、帯状シートの幅方向の伸長率は、中央部よりも端部の方が大きいことを要旨とする。第１布帛及び第２布帛は、織物、編物、または不織布である。 The fabric structure according to the present invention is a fabric structure of a joined fabric in which one end portion of the first fabric and one end portion of the second fabric are joined so as to cover the joined portion of the first fabric and the second fabric. It is provided with a belt-like sheet to be bonded, and the gist of the strip-shaped sheet in the width direction is that the end portion is larger than the center portion. The first fabric and the second fabric are woven fabric, knitted fabric, or nonwoven fabric.
本発明に係る布帛構造においては、帯状シートの幅方向の中央部の伸長率をその端部の伸長率よりも小さくすることによって、接合部に大きな負荷がかかった場合でも、当該接合部の目開きを防止できる。また、帯状シートの幅方向の端部の伸長率をその中央部の伸長率よりも逆に大きくすることによって、帯状シートを接合布帛の幅方向の伸びに追随させることができるので、接合部に対する負荷を軽減することができる。その結果、帯状シートが剥離することや帯状シートに接合布帛の一部が引き摺られる現象（スリップ現象）が発生する危険性を低くすることができる。 In the fabric structure according to the present invention, even if a large load is applied to the joint portion by making the elongation ratio of the central portion in the width direction of the belt-like sheet smaller than the elongation ratio of the end portion, Opening can be prevented. In addition, by increasing the elongation rate of the end portion in the width direction of the belt-like sheet in reverse to the elongation rate of the central portion, the belt-like sheet can be made to follow the elongation in the width direction of the joining fabric. The load can be reduced. As a result, it is possible to reduce the risk that the belt-like sheet is peeled off or a phenomenon in which a part of the bonding fabric is dragged onto the belt-like sheet (slip phenomenon).
帯状シートの端部の幅方向の伸長率は、５％以上であることが好ましい。 The elongation ratio in the width direction of the end portion of the belt-like sheet is preferably 5% or more.
帯状シートの中央部の長さ方向の伸長率は、当該帯状シートの中央部の幅方向の伸長率の１．５倍以上であることが好ましい。 It is preferable that the elongation rate in the length direction of the central portion of the belt-like sheet is 1.5 times or more the elongation rate in the width direction of the central portion of the belt-like sheet.
帯状シートは、少なくとも第１シートおよび第２シートの積層構造を有し、第１シートは中央部に形成され、第２シートは端部および中央部を含む領域に形成されてもよい。この場合の接合布帛は強度に優れる。 The belt-like sheet may have a laminated structure of at least a first sheet and a second sheet, the first sheet may be formed in the central portion, and the second sheet may be formed in a region including the end portion and the central portion. In this case, the bonded fabric is excellent in strength.
また、一つの帯状シートにおいてその中央部に上述の第１シートと同じ伸長率を有する第１伸長部と、その幅方向の両端部に位置し、上述の第２シートと同じ伸長率を有する第２伸長部とを設ける構成を採用してもよい。この場合、シートを設ける工程を１工程省略できるとともに、第１及び第２シートの双方が肌面側に積層されたものと比べ、肌あたりが良好となる。 Further, in one belt-like sheet, a first elongated portion having the same elongation rate as that of the above-described first sheet in the center portion thereof, and a first elongation portion positioned at both ends in the width direction and having the same elongation rate as that of the above-described second sheet. You may employ | adopt the structure which provides 2 extending | stretching parts. In this case, one step of providing the sheet can be omitted, and the skin perception is better than that in which both the first and second sheets are laminated on the skin surface side.
第１シートの幅方向の伸長率を第２シートの幅方向の伸長率よりも小さくすることによって、接合部に大きな負荷がかかった場合でも、当該接合部の目開きを防止できる。また、第２シートの幅方向の伸長率を第１シートの幅方向の伸長率よりも逆に大きくすることによって、第２シートを接合布帛の幅方向の伸びに追随させることができるので、接合部に対する負荷を軽減することができる。その結果、帯状シートが剥離することや上記スリップ現象が発生する危険性を低くすることができる。 By making the elongation rate in the width direction of the first sheet smaller than the elongation rate in the width direction of the second sheet, opening of the joint portion can be prevented even when a large load is applied to the joint portion. In addition, since the second sheet can follow the elongation in the width direction of the bonding fabric by increasing the elongation ratio in the width direction of the second sheet to be larger than the elongation ratio in the width direction of the first sheet. The load on the part can be reduced. As a result, it is possible to reduce the risk of the strip-like sheet peeling off and the occurrence of the slip phenomenon.
第２シートの幅方向および長さ方向の各伸長率は、５％以上であることが好ましい。 Each elongation rate in the width direction and the length direction of the second sheet is preferably 5% or more.
本発明に係る布帛構造において、接合布帛、第１シート、および第２シートの順で積層されていてもよく、接合布帛、第２シート、および第１シートの順で積層されていてもよく、第１シート、接合布帛、および第２シートの順で積層されていてもよい。このうち、第１シート、接合布帛、および第２シートの順で積層された布帛構造が他の布帛構造に比べ最も高い引張強度を有する。 In the fabric structure according to the present invention, the bonded fabric, the first sheet, and the second sheet may be stacked in this order, or the bonded fabric, the second sheet, and the first sheet may be stacked in this order, The first sheet, the bonding fabric, and the second sheet may be laminated in this order. Among these, the fabric structure in which the first sheet, the bonded fabric, and the second sheet are laminated in this order has the highest tensile strength compared to other fabric structures.
本発明に係る接着方法は、第１布帛の一端部と第２布帛の一端部とを接合し、第１布帛と第２布帛との接合布帛の接合部を覆うように帯状シートを接着する接着方法であって、帯状シートの幅方向の伸長率は、中央部よりも端部の方が大きいことを要旨とする。 In the bonding method according to the present invention, one end of the first fabric and one end of the second fabric are bonded, and the belt-like sheet is bonded so as to cover the bonded portion of the bonded fabric of the first fabric and the second fabric. It is a method, Comprising: The elongation rate of the width direction of a strip | belt-shaped sheet | seat makes it a summary that an edge part is larger than a center part.
本発明によれば、接合部に大きな負荷がかかった場合でも、当該接合部の目開きを防止できるとともに、帯状シートが剥離することやスリップ現象が発生する危険性を低くすることができる。 According to the present invention, even when a large load is applied to the joint, it is possible to prevent the opening of the joint, and to reduce the risk of the strip-like sheet peeling or the slip phenomenon.
本実施形態に係る布帛構造は、第１布帛の一端部と第２布帛の一端部とが接合された接合布帛の布帛構造であって、第１布帛と第２布帛との接合部を覆うように接着される帯状シートを備え、帯状シートの幅方向の伸長率は、中央部よりも端部の方が大きいものである。 The fabric structure according to the present embodiment is a fabric structure of a bonded fabric in which one end of the first fabric and one end of the second fabric are bonded so as to cover the bonded portion of the first fabric and the second fabric. The belt-like sheet is bonded to the belt-like sheet, and the elongation rate in the width direction of the belt-like sheet is larger at the end than at the center.
この布帛構造においては、帯状シートの幅方向の中央部の伸長率をその端部の伸長率よりも小さくすることによって、接合部に大きな負荷がかかった場合でも、当該接合部の目開きを防止できる。また、帯状シートの幅方向の端部の伸長率をその中央部の伸長率よりも逆に大きくすることによって、帯状シートを接合布帛の幅方向の伸びに追随させることができるので、接合部に対する負荷を軽減することができる。その結果、図１（ａ）に示すような帯状シートが剥離することや、図１（ｂ）に示すような帯状シートに接合布帛の一部が引き摺られる現象（スリップ現象）が発生する危険性を低くすることができる。 In this fabric structure, even if a large load is applied to the joint portion by making the stretch rate of the central portion in the width direction of the belt-like sheet smaller than the stretch rate of the end portion, opening of the joint portion is prevented. it can. In addition, by increasing the elongation rate of the end portion in the width direction of the belt-like sheet in reverse to the elongation rate of the central portion, the belt-like sheet can be made to follow the elongation in the width direction of the joining fabric. The load can be reduced. As a result, there is a risk that the belt-like sheet as shown in FIG. 1 (a) peels off or a phenomenon (slip phenomenon) in which a part of the bonding fabric is dragged to the belt-like sheet as shown in FIG. 1 (b). Can be lowered.

The composition of the first sheet 30 is 91% nylon (hereinafter referred to as NY) and 9% polyurethane (hereinafter referred to as PU).
第２シート２０は、例えば幅が１０〜２０ｍｍであり、厚みが０．２８ｍｍであり、その組成はＮＹが６２％、ＰＵが３８％である。 The second sheet 20 has, for example, a width of 10 to 20 mm and a thickness of 0.28 mm, and its composition is NY 62% and PU 38%.
第２シート２０の幅方向の伸長率は５％以上２００％以下であることが好ましく、１０％以上１００％以下であることがより好ましい。第２シート２０の長さ方向の伸長率は５％以上２００％以下であることが好ましく、１０％以上１００％以下であることがより好ましい。 The elongation ratio in the width direction of the second sheet 20 is preferably 5% or more and 200% or less, and more preferably 10% or more and 100% or less. The elongation ratio in the length direction of the second sheet 20 is preferably 5% or more and 200% or less, and more preferably 10% or more and 100% or less.
また、第１シート３０の幅方向の伸長率は第２シート２０の幅方向の上記伸長率よりも小さく、すなわち１０％未満であることが好ましく、５％未満であることがより好ましい。また、第１シート３０の長さ方向の伸長率は、その幅方向の伸長率の１．５倍以上である。 In addition, the elongation rate in the width direction of the first sheet 30 is smaller than the elongation rate in the width direction of the second sheet 20, that is, less than 10%, and more preferably less than 5%. Moreover, the elongation rate in the length direction of the first sheet 30 is 1.5 times or more of the elongation rate in the width direction.
