Description
本発明は、面ファスナーに関し、より詳しくは、係合使用時のせん断係合力は大きいが、意図しない外れが発生し難く、係合を解除する際は小さな力で剥離でき、相手の面ファスナーを傷め難く、かつ剥離音の少ない面ファスナーに関するものである。 More specifically, the present invention relates to a hook-and-loop fastener, and more specifically, the shear engagement force is large when engaged. However, unintentional detachment hardly occurs, and when releasing the engagement, it can be peeled off with a small force. The present invention relates to a hook-and-loop fastener that is hard to be damaged and has little peeling sound.
近年、腰痛を予防したり、腰痛を緩和したりする腰用コルセット（以下、「腰痛ベルト」という。）、膝装着用サポーター、手袋、血圧計の腕巻き部や乳幼児のおむつカバーや使い捨ておむつなどにも面ファスナーが使用されているが、例えば、腰痛ベルトの装着を外すため、或いはおむつカバーやおむつを取り替えるために面ファスナーを剥がすと、バリバリという不快音が出て、周囲に気を遣う、乳幼児の睡眠を妨げてしまうなどの問題がある。さらに、何回も繰り返すうちに係合力が低下し、剥離すべきでないときに剥離するという問題も有している。 In recent years, waist corsets (hereinafter referred to as “back pain belts”) to prevent or relieve back pain, supporters for knees, gloves, arm winding parts of blood pressure monitors, infant diaper covers, disposable diapers, etc. The hook-and-loop fastener is also used, but for example, when removing the hook-and-loop belt to remove the back pain belt or to replace the diaper cover or diaper, an unpleasant noise is heard and the surroundings are taken care of. There are problems such as disturbing infants' sleep. Furthermore, there is a problem that the engagement force is reduced over and over again and peels off when it should not be peeled off.
このような問題点を解消する面ファスナーとして、例えば特許文献１には、モノフィラメントよりなるステムを基板に対して一方向にのみ斜めに植設した面ファスナーが提案されている。しかしながら、モノフィラメントからなるステムの場合には、面ファスナーの製造上、係合素子（ステム）は、あまり太く出来ず、さらに係合素子密度も限られ、高重量のものを係合することができず、さらに全てのステムをほぼ同一方向に傾けることが極めて難しく、一部の他方向を向いているステムが係合を妨げ、結果として総合的な係合力発現を大きく損なうという欠点を有している。さらに、このようなモノフィラメントを一方向に傾けた面ファスナーの場合には、使用中に、ステムに力がかかるとモノフィラメントの傾き方向を損なうことが多く、例えばモノフィラメントを逆方向に倒す力が加わった場合には、モノフィラメントの傾き方向が大きく変化し、係合力が大きく低下し、場合によっては係合力が全く消失してしまうこととなる。 As a hook-and-loop fastener that solves such problems, for example, Patent Document 1 proposes a hook-and-loop fastener in which a stem made of a monofilament is obliquely implanted in only one direction with respect to a substrate. However, in the case of a stem made of monofilament, the engaging element (stem) cannot be made very thick in the manufacture of the hook-and-loop fastener, and the engaging element density is limited, so that a heavy one can be engaged. In addition, it is extremely difficult to incline all the stems in almost the same direction, and some stems facing in the other direction prevent the engagement, resulting in a significant loss of the overall engagement force. Yes. Furthermore, in the case of a hook-and-loop fastener in which such a monofilament is tilted in one direction, a force applied to the stem during use often impairs the tilt direction of the monofilament. For example, a force to tilt the monofilament in the reverse direction is added. In some cases, the inclination direction of the monofilament changes greatly, the engagement force decreases greatly, and in some cases, the engagement force disappears at all.
また、特許文献２には、合成樹脂の糸引き現象を利用して、一方向に傾いたフック素子を有する係合力に方向性を有する面ファスナーが記載されているが、このような面ファスナーでは、個々のフック素子は係合力が低く、しかもフック素子密度を高めることも困難であり、したがって高い係合力を有する面ファスナーを製造することは構造上難しい。 Further, Patent Document 2 describes a hook-and-loop fastener having a directionality to an engaging force having a hook element inclined in one direction by using a yarn pulling phenomenon of a synthetic resin. Each hook element has a low engaging force, and it is difficult to increase the hook element density. Therefore, it is structurally difficult to manufacture a hook-and-loop fastener having a high engaging force.
さらに、特許文献３には、係合−剥離を繰り返すことで面ファスナーのループが切断したり、フックが破損することにより係合力が低下するという問題点や係合力が必ずしも高くないという問題点、また剥離する際にバリバリという大きな音がするという問題点を解消できる面ファスナーが提案されている。当該面ファスナーは、熱可塑性樹脂からなる基板上に同樹脂からなる多数のステムが存在しており、該ステムは、その高さの中間部分とその先端部分でほぼ同一の幅を有しており、かついずれのステムも基板に対してほぼ同一の一方向に傾きを有しており、さらに該傾き方向に対して交差する方向に多数のステムが並列に並んでおり、さらにこのようなステム列が基板上に複数列存在している、係合力に方向性を有する面ファスナーである。 Furthermore, in Patent Document 3, the loop of the hook-and-loop fastener is cut by repeating the engagement-peeling, or the engagement force is reduced due to the hook being broken or the engagement force is not necessarily high, Further, a hook-and-loop fastener has been proposed that can eliminate the problem of a loud noise when peeling. The hook-and-loop fastener has a large number of stems made of the same resin on a substrate made of a thermoplastic resin, and the stem has substantially the same width at the intermediate portion and the tip portion thereof. Each of the stems has an inclination in substantially the same direction with respect to the substrate, and a number of stems are arranged in parallel in a direction intersecting the inclination direction. Is a hook-and-loop fastener that has a plurality of rows on the substrate and has a directionality to the engaging force.
しかしながら、特許文献３に記載の面ファスナーにおいても、一定方向の力が負荷されている状態での係合力は良好であるが、負荷が緩むと係合面が外れるという問題があった。例えば、腰痛ベルト等のサポーターの締め付け具とした場合、身体の動き・腹圧の変動等で外れる恐れがあり、特に高齢者用サポーター等では、せん断係合力が大きく、剥がし易い面ファスナー（剥離力が小）で使用中に剥がれる（外れる）恐れのない面ファスナーが望まれていた。 However, the hook-and-loop fastener described in Patent Document 3 also has a good engagement force in a state where a force in a certain direction is applied, but there is a problem that the engagement surface is released when the load is loosened. For example, if it is used as a fastener for a supporter such as a low back pain belt, it may come off due to fluctuations in body movement, abdominal pressure, etc. Especially for elderly supporters, etc., it has a large shear engagement force and is easy to peel off. However, there has been a demand for a hook-and-loop fastener that does not have a risk of peeling off during use.
本発明は、係合使用時のせん断係合力は大きく、意図しない外れが発生し難く、係合を解除する際は小さな力で剥離でき、相手の面ファスナーを傷め難く、かつ剥離音の少ない面ファスナーを提供することを目的とする。 The present invention has a large shearing engagement force during engagement use, is unlikely to cause unintentional detachment, can be peeled off with a small force when releasing the engagement, is difficult to damage the other surface fastener, and has less peeling sound The object is to provide a fastener.

If the area of the region (2) is in the range of 15 to 35% of the total area of the hook-and-loop fastener, it has an excellent engagement force and at the same time, the inclined engagement element group region engagement is unintentionally released (peeled) ), And it is possible to suppress peeling noise when releasing the engagement.

傾斜係合素子群領域（１）は、図２の斜視図に示すように多数の傾斜係合素子２が基体１から所定の角度で傾斜して伸びて存在しており、かつ、傾斜係合素子２が基体１に対してほぼ同一の方向（図２では、Ｔ（Ｙ）方向）に傾斜している。傾斜係合素子は、高い係合力と傾斜角度の均一性及び傾斜方向の均一性が得られる点から基体１と傾斜係合素子２を一体に押出成形して形成した成形面ファスナーが好ましい。
しかし、余り高い係合力が必要ない場合は、織編基布を基体とし、これにモノフィラメントを植設し一定方向に傾斜させた面ファスナーとすることができる。Inclined engagement element group region (1)
In the inclined engagement element group region (1), as shown in the perspective view of FIG. 2, a large number of inclined engagement elements 2 are inclined and extended at a predetermined angle from the base 1, and the inclined engagement is performed. The element 2 is inclined in substantially the same direction (T (Y) direction in FIG. 2) with respect to the base 1. The inclined engaging element is preferably a molded surface fastener formed by integrally extruding the base body 1 and the inclined engaging element 2 from the viewpoint that high engaging force, uniform inclination angle and uniform inclination direction can be obtained.
However, when an excessively high engagement force is not required, a hook-and-loop base fabric having a woven / knitted base fabric as a base and a monofilament planted thereon and inclined in a certain direction can be obtained.
一体に押出成形して形成した成形面ファスナーの傾斜係合素子は、図４に拡大側面図として示すように、基体１から傾斜して突出したステム部３と、その先端にステム部の中心軸に対して、その中心軸が基体１の方向に変曲し、さらに最先端が丸味を帯びている頭部４を有していることが好ましい。基体とステム部３との傾き角度（θ）は、２５〜７０°が好ましく、２５°未満の場合には、ループ繊維に引っかかり難く、７０°を越える場合には引っかかったループ繊維が外れ易く、共に充分な係合力が得られないこととなる。より好ましくは、３０〜６０°の範囲である。また、ステム部が傾くことにより、ループ繊維を保持するステム部の軒下部分が形成されていることが必要であり、図４に示すＤの距離が０．２〜３．０ｍｍとなる程度が係合力の発現性の観点から好ましい。
また、傾斜係合素子２の高さは図４で示すＨが０．３〜３．０ｍｍであるのが好ましい。傾斜係合素子の高さＨが高くなると特定の傾斜係合素子に力がかかった場合に傾斜係合素子が曲がったり折れたりする。逆に低すぎると、ループ素子と引っかかり難く、係合力が低下することとなる。より好ましくは０．４〜１．５ｍｍの範囲である。As shown in FIG. 4 as an enlarged side view, the inclined engaging element of the molded surface fastener formed by extrusion molding integrally has a stem portion 3 that protrudes inclined from the base 1, and a central axis of the stem portion at the tip thereof. On the other hand, it is preferable that the central axis bends in the direction of the base body 1 and the head 4 has a rounded end. The inclination angle (θ) between the substrate and the stem portion 3 is preferably 25 to 70 °. When the angle is less than 25 °, the loop fiber is hardly caught, and when it exceeds 70 °, the caught loop fiber is easily detached. In both cases, sufficient engagement force cannot be obtained. More preferably, it is the range of 30-60 degrees. Further, it is necessary that the eaves portion of the stem portion for holding the loop fiber is formed by the inclination of the stem portion, and the distance of D shown in FIG. 4 is about 0.2 to 3.0 mm. It is preferable from the viewpoint of the resultant power.
Moreover, as for the height of the inclination engagement element 2, it is preferable that H shown in FIG. 4 is 0.3-3.0 mm. When the height H of the tilt engagement element increases, the tilt engagement element bends or breaks when a force is applied to a specific tilt engagement element. On the other hand, if it is too low, it will be difficult to catch the loop element, and the engaging force will be reduced. More preferably, it is the range of 0.4-1.5 mm.
また、傾斜係合素子は、頭部４が図５に示すように基板方向に曲がっていてもよい。このように曲がっていることにより、傾斜係合素子に係合しているループ素子は傾斜係合素子の高さ方向に単に張力がかかっただけで係合が剥がれるということを防ぐことができることとなる。より好ましくは、図５に示す基板方向への曲がりＦが０．０５〜０．５ｍｍで、かつ傾斜係合素子の高さＨの１／５０〜１／５の範囲である。 Further, the head 4 may be bent in the substrate direction as shown in FIG. By bending in this way, it is possible to prevent the loop element engaged with the inclined engagement element from being disengaged simply by applying a tension in the height direction of the inclined engagement element. Become. More preferably, the bend F in the substrate direction shown in FIG. 5 is in the range of 0.05 to 0.5 mm and 1/50 to 1/5 of the height H of the inclined engagement element.
傾斜係合素子群領域（１）としては、図２に示す面ファスナーが好ましい一例として挙げられる。同図に示す面ファスナーは、熱可塑性樹脂からなる基体（以下、「基板」ともいう場合がある。）１とその上に存在する同樹脂からなる前記の側面形状を有する傾斜係合素子２から構成される。基板（基体）１の厚さとしては、０．１〜１．０ｍｍが好ましい。傾斜係合素子２は、いずれも、基板１に対してほぼ同一の一方向に傾きを有しており（図２ではＴ方向、長手方向でもある。）、かつ、該傾き方向に対して交差する方向（図２および図６ではＸ方向）に、傾斜係合素子幅（図６で示すＷ）の０．５〜５．０倍の間隔（図６で示すＳ１）をおいて多数の傾斜係合素子２が並列に並んでおり、さらにこのような傾斜係合素子列が基板１上に平行に複数列（図２では３列）存在しており、そして個々の傾斜係合素子は、傾斜係合素子の高さの中間部分であるステム部３と頭部４でほぼ同一幅を有している。これらの傾斜係合素子が同一方向に傾いていない場合、すなわち個々の傾斜係合素子２がそれぞれ別々の方向に傾いている場合には、特定方向に高い係合力を発現せず、係合力を殆ど有しないか、あるいは有していても極めて低いものとなる。本発明において領域（１）の全ての傾斜係合素子２が全く同一方向に傾いている場合がもっとも好ましいが、ごく僅かならば同一方向に傾いていない傾斜係合素子が存在していてもよい。 As the inclined engaging element group region (1), a hook-and-loop fastener shown in FIG. 2 is a preferred example. The hook-and-loop fastener shown in FIG. 1 includes a base body (hereinafter also referred to as “substrate”) 1 made of a thermoplastic resin and an inclined engagement element 2 having the above-described side surface shape made of the same resin. Composed. As thickness of the board | substrate (base | substrate) 1, 0.1-1.0 mm is preferable. Each of the inclined engaging elements 2 has an inclination in substantially the same direction with respect to the substrate 1 (also in the T direction and the longitudinal direction in FIG. 2), and intersects the inclination direction. In the direction (X direction in FIGS. 2 and 6), a large number of inclinations are provided at intervals (S1 shown in FIG. 6) of 0.5 to 5.0 times the inclination engaging element width (W shown in FIG. 6). The engaging elements 2 are arranged in parallel, and there are a plurality of such inclined engaging element rows in parallel on the substrate 1 (three rows in FIG. 2). The stem portion 3 and the head portion 4 which are intermediate portions of the height of the inclined engagement element have substantially the same width. When these inclined engagement elements are not inclined in the same direction, that is, when the individual inclined engagement elements 2 are inclined in different directions, a high engagement force is not expressed in a specific direction, and the engagement force is increased. It has little or even very little. In the present invention, it is most preferable that all the inclined engagement elements 2 in the region (1) are inclined in exactly the same direction, but there may be inclined engagement elements that are not inclined in the same direction if there is very little. .
次に、本発明の傾斜係合素子群領域（１）を有する面ファスナーを製造する方法について説明する。まず、熱可塑性樹脂を図７に示すようなノズル５から溶融押出し、基板の表面に、基板に対して傾斜しかつ連続している列条を有するテープを成形する。 Next, a method for producing a surface fastener having the inclined engagement element group region (1) of the present invention will be described. First, a thermoplastic resin is melt-extruded from a nozzle 5 as shown in FIG. 7, and a tape having rows that are inclined and continuous with respect to the substrate is formed on the surface of the substrate.
この種の成形物は、押し出し成形だけではなく、射出成型法でも製造可能である。しかし、長さの異なる各種の雄型素子列を有する面ファスナーを自由に製造でき、しかも、延伸されていることから基板の強度にも優れ、かつ傾斜係合素子が剥がれ難いこと、さらに係合素子密度が高い面ファスナーを容易に作製できることから押し出し成形を用いるのが好ましい。 This type of molding can be produced not only by extrusion molding but also by injection molding. However, it is possible to freely manufacture hook-and-loop fasteners having various male element rows of different lengths, and since they are stretched, they are excellent in strength of the substrate, and the inclined engagement elements are difficult to peel off, and are further engaged. Extrusion molding is preferably used because a surface fastener having a high element density can be easily produced.
図７に示す６が基板形成用スリットであり、７が傾斜係合素子すなわちステム部及び頭部を構成することとなる同一方向に傾斜した複数の線状スリットである。 Reference numeral 6 shown in FIG. 7 denotes a substrate forming slit, and 7 denotes a plurality of linear slits inclined in the same direction that constitute the inclined engaging elements, that is, the stem portion and the head.
使用される熱可塑性樹脂としては、ポリオレフィン系樹脂、ポリエステル系樹脂、ポリアミド系樹脂、エチレン−ビニルアルコール共重合体などが挙げられ、特に、延伸性や溶融押出し安定性、さらにステム強度の観点から、ポリプロピレンで代表されるポリオレフィン系樹脂が好適例として挙げられる。図７のスリットを用いた場合には基板表面に傾斜を有する列条が７本等間隔で存在しているテープが得られる。列条の本数としては、３〜６０本が適当であり、好ましくは５〜４０本である。テープ幅としては、延伸前で３０〜９０ｍｍが好ましい。 Examples of the thermoplastic resin used include polyolefin resins, polyester resins, polyamide resins, ethylene-vinyl alcohol copolymers, and the like, particularly from the viewpoint of stretchability, melt extrusion stability, and stem strength. A preferred example is a polyolefin resin typified by polypropylene. When the slits shown in FIG. 7 are used, a tape is obtained in which seven strips having an inclination are present at equal intervals on the substrate surface. The number of rows is suitably 3 to 60, preferably 5 to 40. The tape width is preferably 30 to 90 mm before stretching.
次に得られたテープの表面に存在する列条に小間隔で付け根付近まで切れ目を入れる。切れ目の間隔としては０．２〜２．０ｍｍが適切である。次いで、テープを長さ方向に延伸する。延伸倍率としては、延伸後のテープ長さが元のテープの長さの１．５〜４．０倍となる程度が好ましい。この延伸により、列条に入れられた切れ目が広がり、列条が、独立した多数の傾斜係合素子からなる傾斜係合素子群領域形成用面ファスナーとなる。 Next, a cut is made in the line existing on the surface of the obtained tape to the vicinity of the root at small intervals. An appropriate interval between the cuts is 0.2 to 2.0 mm. Next, the tape is stretched in the length direction. The stretching ratio is preferably such that the tape length after stretching is 1.5 to 4.0 times the length of the original tape. By this stretching, the cuts formed in the rows are widened, and the rows become a hook-and-loop fastener for forming a sloped engagement element group region composed of a large number of independent sloped engagement elements.
一方、本発明の雄型係合素子群領域（２）は、雄型係合素子から形成される。本発明において雄型係合素子とは、布製の基布に鉤状係合素子を立設したフック係合素子や、プラスチックの基板に鉤状、キノコ状、鏃（矢じり）状などの係合素子を成形立設したものを挙げることができる。なかでも、基布に鉤状係合素子を立設した雄型係合素子が、繰り返し使用に耐え得ることから好ましい。図３は基体１１上に鉤状の雄型係合素子１２を有する面ファスナーを示している。本発明では、特に、基体１１としての織物基布に織り込んだモノフィラメントを表面にループ状に存在させ、そのループの側部を切断して鉤としたフック状の雄型係合素子１２である図３に示すような面ファスナーが、係合力が高く、形態が崩れ難く、さらに繰り返し使用に耐え得ることからもっとも好ましい。また、キノコ状の頭部を有するモノフィラメントからなる雄型係合素子は、モノフィラメントの頭部を溶融させて球状にすることにより得ることができる。 On the other hand, the male engagement element group region (2) of the present invention is formed of male engagement elements. In the present invention, the male engagement element refers to a hook engagement element in which a hook-like engagement element is erected on a cloth base cloth, or a hook-like, mushroom-like, hook-like (arrowhead) -like engagement with a plastic substrate. A device in which an element is formed upright can be mentioned. Among these, a male engagement element in which a hook-like engagement element is erected on a base fabric is preferable because it can withstand repeated use. FIG. 3 shows a hook-and-loop fastener having a hook-shaped male engagement element 12 on a base 11. In the present invention, in particular, the figure shows a hook-like male engagement element 12 in which monofilaments woven into a woven fabric as a base 11 are present on the surface in a loop shape, and a side portion of the loop is cut to form a hook. A hook-and-loop fastener as shown in Fig. 3 is most preferable because it has a high engaging force, is not easily deformed, and can withstand repeated use. A male engagement element made of a monofilament having a mushroom-shaped head can be obtained by melting the head of the monofilament into a spherical shape.
雄型係合素子を合成繊維のモノフィラメントから形成する場合は、その繊度が１００〜９００ｄｔｅｘの範囲であることが好ましく、２００〜６００ｄｔｅｘの範囲であることがより好ましい。
雄型係合素子群領域（２）の雄型係合素子密度、及び係合力としては、通常、一般的に、クラレファスニング株式会社から販売されている織面ファスナーが有している程度のものを用いることができる。When the male engagement element is formed from a monofilament of synthetic fiber, the fineness is preferably in the range of 100 to 900 dtex, and more preferably in the range of 200 to 600 dtex.
The male engaging element density and the engaging force of the male engaging element group region (2) are generally those that are generally possessed by woven surface fasteners sold by Kuraray Fastening Co., Ltd. Can be used.
雄型係合素子群領域（２）の基体として基布を用いる場合は、基布を構成する繊維としては、ポリエステル系、ポリアミド系、ポリオレフィン系等が挙げられる。なかでも、ポリエステル系の繊維、例えばポリエチレンテレフタレート系の繊維を基布およびフック状などの雄型係合素子用繊維として用いたものが、フックが倒れ難く、いつまでも高い係合力が得られる点から好ましい。 When a base fabric is used as the base of the male engagement element group region (2), examples of the fibers constituting the base fabric include polyester, polyamide, and polyolefin. Of these, polyester fibers, for example, polyethylene terephthalate fibers, which are used as fibers for male engagement elements such as base fabrics and hooks, are preferable because the hooks are difficult to collapse and a high engagement force can be obtained forever. .
また、雄型係合素子群領域（２）を一体成形された雄型面ファスナーとしてもよく、この場合の雄型係合素子は、前述の傾斜係合素子における場合と同様に、プラスチックの基板に鉤状、キノコ状、鏃状及び膨頭状などの係合素子を成形立設したものであってもよい。この成形面ファスナーは、傾斜係合素子面ファスナーと鏃状雄型係合素子面ファスナーを縫製一体化する必要がなく、一挙に両者が存在している面ファスナーが製造できることから、製造が容易でかつ安価に製造でき、しかも、縫製した場合に生じやすいミシン目からの面ファスナーの裂断という問題を有さず、特に優れたものである。さらに、押し出し成形で製造することによって、一体成形された雄型面ファスナーとしての強度に優れる点で好ましい。
図８は、雄型係合素子１２として基板１１の上にキノコ型係合素子が構成される場合を示している。
図１７は、雄型係合素子１２として基板１１の上に上記キノコ型係合素子と同様に鏃型係合素子が構成される場合を示しているが、説明簡略のため、以下キノコ型係合素子で代表して説明する。
各キノコ型係合素子１２は、ステム部１３とその上部に広がる傘部１４からなり、かつ係合素子列方向Ｘに直交する方向（Ｙ方向）に傘部１４はステム部１３からはみ出して拡がっているが、係合素子列方向（Ｘ方向）には傘部１４は拡がりを有しておらずにステム部１３から傘部先端部に至るまでほぼ同一の幅（Ｗ）を有している。このような構造は、前述の傾斜係合素子群の製造方法と同様、すなわち熱可塑性樹脂をスリット状ノズルから押し出して、基板上に複数の係合素子用列条を有するテープ状物を形成し、そして、係合素子用列条に、それと交差する方向にその先端から根元に至る切れ目を入れ、そして延伸することにより形成されるものであり、ループ素子との高い係合力を得る上でこのような構造を有していることが重要である。The male engagement element group region (2) may be a male surface fastener integrally formed. In this case, the male engagement element is a plastic substrate as in the case of the inclined engagement element described above. Alternatively, a hook-shaped, mushroom-shaped, hook-shaped or swollen-shaped engaging element may be formed and erected. This molded surface fastener is easy to manufacture because it is not necessary to sew and integrate the inclined engaging element surface fastener and the hook-shaped male engaging element surface fastener, and a surface fastener having both of them can be manufactured at once. In addition, it can be manufactured at low cost, and does not have the problem of tearing of the hook-and-loop fastener from the perforation that is likely to occur when sewing, and is particularly excellent. Furthermore, it is preferable to produce by extrusion molding because it is excellent in strength as an integrally molded male surface fastener.
FIG. 8 shows a case where a mushroom type engagement element is formed on the substrate 11 as the male type engagement element 12.
FIG. 17 shows a case where a saddle-type engagement element is formed on the substrate 11 as the male engagement element 12 in the same manner as the above-described mushroom-type engagement element. A description will be given on behalf of a composite element.
Each mushroom-type engaging element 12 includes a stem portion 13 and an umbrella portion 14 extending above the stem portion 13, and the umbrella portion 14 extends from the stem portion 13 in a direction perpendicular to the engaging element row direction X (Y direction). However, in the engaging element row direction (X direction), the umbrella part 14 does not have an expansion, but has substantially the same width (W) from the stem part 13 to the tip part of the umbrella part. . Such a structure is the same as the above-described manufacturing method of the inclined engagement element group, that is, a thermoplastic resin is extruded from the slit-like nozzle to form a tape-like object having a plurality of engagement element rows on the substrate. In addition, the engagement element row is formed by making a cut from the tip to the root in a direction intersecting with the line and extending the line, and in order to obtain a high engagement force with the loop element, It is important to have such a structure.
各キノコ型係合素子の傘部の広がり部の長さ（Ｐ）としては０．４〜０．９ｍｍ、特に０．５〜０．７ｍｍの範囲が係合力の点で好ましい。 The length (P) of the expanding portion of the umbrella portion of each mushroom-type engaging element is preferably in the range of 0.4 to 0.9 mm, particularly 0.5 to 0.7 mm in terms of engaging force.
上記したように、本発明の面ファスナーの雄型係合素子群領域（２）に用いる成形によるキノコ型係合素子は、熱可塑性樹脂からなる基板とその上に存在する同樹脂からなる多数のキノコ型係合素子から構成される。基板の厚さとしては、０．１〜０．４ｍｍ、特に０．２〜０．３ｍｍの範囲が好ましい。また、基板の幅（係合素子列に直交するＹ方向の幅）としては５〜２００ｍｍ、特に１０〜１００ｍｍが好ましい。余りに幅広い場合には、係合素子用列条に高速で切れ目を入れるのが困難となる。 As described above, the mushroom type engaging element formed by molding used in the male engaging element group region (2) of the surface fastener of the present invention has a substrate made of a thermoplastic resin and a large number of the same resin existing thereon. It is composed of a mushroom type engaging element. The thickness of the substrate is preferably in the range of 0.1 to 0.4 mm, particularly 0.2 to 0.3 mm. Further, the width of the substrate (the width in the Y direction orthogonal to the engagement element row) is preferably 5 to 200 mm, particularly preferably 10 to 100 mm. If it is too wide, it will be difficult to cut the engagement element rows at high speed.
また、本発明の雄型係合素子群領域（２）のキノコ型係合素子を構成するステム部１３の係合素子列方向の幅（Ｗ）としては、０.２５〜０.３５ｍｍ、特に０.２８〜０．３３ｍｍの範囲が好ましい。また、ステム部間の間隔、すなわち隣り合う係合素子列との間隔（Ｑ）としては、０.５〜１.５ｍｍ、特に０.８〜１.２ｍｍの範囲が好ましく、係合素子列方向（Ｘ方向）に隣り合うキノコ型係合素子の間隔（Ｓ２）としては、Ｗ：Ｓ２が１：０．７〜１：１．３となることが好ましく、特にＷ：Ｓ２が１：０．８〜１：１．２の範囲がより好ましい。Ｗ：Ｓ２の比が１：０．７よりＳ２が小さい場合には、延伸が不充分にしか行なわれていないこととなるため、ループ状係合素子がキノコ型係合素子に係合するだけの十分な切れ目（すなわちキノコ型係合素子間隔）を有していないこととなり、さらに基板１１も殆ど延伸されていないことから基板強度が不充分となり、逆に１：１．３を越えてＳ２が大きい場合には、延伸による分子配向により縫着する場合、縫目に従って基板が裂け易いこととなる。 Further, the width (W) in the engagement element row direction of the stem portion 13 constituting the mushroom type engagement element of the male engagement element group region (2) of the present invention is 0.25 to 0.35 mm, particularly A range of 0.28 to 0.33 mm is preferable. The interval between the stem portions, that is, the interval (Q) between adjacent engaging element rows is preferably in the range of 0.5 to 1.5 mm, particularly 0.8 to 1.2 mm. As an interval (S2) between mushroom-type engaging elements adjacent in the (X direction), W: S2 is preferably 1: 0.7 to 1: 1.3, and particularly W: S2 is 1: 0. A range of 8 to 1: 1.2 is more preferable. When the ratio of W: S2 is smaller than 1: 0.7, the stretching is performed only insufficiently, so that the loop engaging element only engages with the mushroom type engaging element. In other words, the substrate 11 is not sufficiently stretched (ie, the distance between the mushroom type engagement elements), and the substrate 11 is hardly stretched. In the case where is large, when sewing is performed by molecular orientation by stretching, the substrate is easily torn according to the stitches.
また、係合素子列方向と直交する方向（Ｙ方向）のステム幅（Ｒ）としては、０．１〜０．５ｍｍ、特に０．１〜０．４ｍｍの範囲が好ましく、隣り合う係合素子列間の傘部での間隔（Ｚ）としては、０．２〜１．２ｍｍ、特に０．５〜０．９ｍｍの範囲が好ましい。更に、係合素子の高さ（Ｈ）の１０〜４０％、特に２０〜２５％が傘部であるのが好ましい。
これらの大きさや範囲を満足していることが係合力および係合し易さおよび肌触り感を達成し、さらに基板の裂け難さを得る上で好ましい。The stem width (R) in the direction orthogonal to the engaging element row direction (Y direction) is preferably in the range of 0.1 to 0.5 mm, particularly 0.1 to 0.4 mm, and adjacent engaging elements. The distance (Z) between the umbrellas between the rows is preferably in the range of 0.2 to 1.2 mm, particularly 0.5 to 0.9 mm. Furthermore, it is preferable that 10 to 40%, particularly 20 to 25% of the height (H) of the engaging element is the umbrella portion.
Satisfying these sizes and ranges is preferable for achieving the engagement force, the ease of engagement, and the feeling of touch, and the difficulty of tearing the substrate.
さらに、本発明において、基板幅［キノコ型係合素子列と直交する方向（Ｙ方向）の基板の幅］１ｃｍ当たりキノコ型係合素子列が５〜１５本、好ましくは６〜１０本存在するのが好ましい。少なすぎても、また、多すぎても係合力が低下する。 Furthermore, in the present invention, there are 5 to 15, preferably 6 to 10, mushroom-type engaging element arrays per 1 cm of substrate width [the width of the substrate in the direction orthogonal to the mushroom-type engaging element array (Y direction)]. Is preferred. If the amount is too small or too large, the engagement force decreases.
なお、本発明において、キノコ型係合素子は、図９に示すノズル１５を用い、基板形成用スリット１６とステム部及び傘部形成用スリット１７から熱可塑性樹脂を溶融押出して形成される。キノコ型係合素子は後述する方法により製造されるが、ステム部の根元付近は、ステム部の中間部分と比べて係合素子列方向の太さが太くなりがちである。そのような場合には、本発明で言う寸法は、ステム部の高さの中間部での長さを意味する。
なお、上記した係合素子の寸法や間隔は、任意に選んだ係合素子または係合素子間等１０個の値の平均値である。In the present invention, the mushroom-type engaging element is formed by melt-extruding a thermoplastic resin from the substrate forming slit 16 and the stem portion and umbrella portion forming slit 17 using the nozzle 15 shown in FIG. Although the mushroom-type engaging element is manufactured by a method described later, the thickness in the engaging element row direction tends to be thicker in the vicinity of the root of the stem portion than in the intermediate portion of the stem portion. In such a case, the dimension said by this invention means the length in the intermediate part of the height of a stem part.
The dimensions and intervals of the engagement elements described above are average values of 10 values such as arbitrarily selected engagement elements or between engagement elements.
また、本発明の面ファスナーにおいて、係合素子のステム部高さの中間部分における基板と平行方向における個々のステム部の断面積が０．０５〜０．２０ｍｍ2であるのが好ましい。断面積が０.０５ｍｍ2未満の場合には、係合素子が曲がり易く、場合によっては係合素子の傘部がステム部から切断されることも生じる。一方、０．２０ｍｍ2を越える場合には、ステム部が太すぎることにより係合力の低下を招く。ここでいう断面とは、係合素子のステム部の基板に対して平行な面でのステム部の高さの中間部の断面である。In the hook-and-loop fastener of the present invention, it is preferable that the cross-sectional area of each stem portion in the direction parallel to the substrate in the intermediate portion of the stem portion height of the engaging element is 0.05 to 0.20 mm 2 . When the cross-sectional area is less than 0.05 mm 2 , the engaging element is easily bent, and in some cases, the umbrella portion of the engaging element is cut from the stem portion. On the other hand, if it exceeds 0.20 mm 2 , the stem portion is too thick, leading to a decrease in engagement force. A cross section here is a cross section of the intermediate part of the height of the stem part in the surface parallel to the board | substrate of the stem part of an engagement element.
本発明の面ファスナーは、領域（１）の基体、領域（２）の基体、領域（１）の傾斜係合素子および領域（２）の雄型係合素子が一体成形されてなるものとすることができる。
かかる面ファスナーは、図１０（Ｂ）にその側面を示すように、傾斜係合素子２の基板１及び雄型係合素子１２の基板１１を共通とし、かつ、傾斜係合素子１及び雄型係合素子１２を構成する熱可塑性樹脂を共通として、図１１に示すノズル１８を用いて、基板形成用スリット１９及び傾斜係合素子のステム部及び頭部形成用スリット７、雄型係合素子のステム部及び傘部（突起）形成用スリット１７から溶融樹脂を押出成形し、前述と同様に係合素子用列条に、それと交差する方向にその先端から根元に至る切れ目を入れ、そして延伸することにより製造できる。領域(１)及び領域（２）のそれぞれの係合素子用列条数や間隔、太さ等は、要求される面ファスナーの性能に応じて、適宜変更される。In the surface fastener of the present invention, the base body in the region (1), the base body in the region (2), the inclined engagement element in the region (1) and the male engagement element in the region (2) are integrally formed. be able to.
As shown in FIG. 10B, the hook-and-loop fastener has the substrate 1 of the inclined engagement element 2 and the substrate 11 of the male engagement element 12 in common, and the inclined engagement element 1 and the male mold. The common thermoplastic resin constituting the engaging element 12 is used, and the nozzle 18 shown in FIG. 11 is used to form the substrate forming slit 19, the stem portion of the inclined engaging element and the head forming slit 7, the male engaging element. The molten resin is extruded from the stem part and the umbrella part (projection) forming slit 17, and the cut line extending from the tip to the root is made in the direction intersecting with the line for the engaging element in the same manner as described above, and stretched. Can be manufactured. The number of rows for the engaging elements, the interval, the thickness, etc. of each of the regions (1) and (2) are appropriately changed according to the required performance of the surface fastener.

この種の面ファスナーは、上記の製造工程において、押出後の係合素子用列条に、それと交差する方向にその先端から根元に至る切れ目を入れるに際し、切れ目を形成するためのカッターの刃の厚みが同一のものを用いて、領域(１)に対応する部位と領域（２）に対応する部位に同様に切れ目を入れ、その後に延伸することによって製造することができる。Further, in the surface fastener of the present invention, the inclined engagement elements in the region (1) are arranged in a row at intervals S1 in the direction orthogonal to the longitudinal direction (X direction) as shown in FIG. , The male engaging element in the region (2) has engaging projections (umbrella portions 14) extending in opposite directions from the stem portion 13 to the head portion 14 as shown in FIG. The hook-and-loop fastener can be formed as a hook-and-loop fastener that is arranged in a row at intervals S2 in the direction (X) orthogonal to the interval, and the intervals S1 and S2 are substantially the same.
This type of hook-and-loop fastener has a cutter blade for forming a cut when the cut from the tip to the root is made in the direction intersecting with the line for the engaging element after extrusion in the manufacturing process described above. Using the same thickness, a portion corresponding to the region (1) and a portion corresponding to the region (2) are similarly cut, and then stretched.
また、本発明の面ファスナーは、領域（１）の傾斜係合素子と領域（２）の雄型係合素子が共にループ面ファスナーと係合・解除可能な面ファスナーとすることが好ましい。
本発明の面ファスナーを構成する傾斜係合素子及び雄型係合素子を機能させるためには、これらと係合する係合素子が必須であり、係合させる側の面には複数のループ状係合素子を有するループ面ファスナーとすることが好ましい。The hook-and-loop fastener of the present invention is preferably a hook-and-loop fastener that can engage and release the loop hook-and-loop fastener together with the inclined engaging element in the region (1) and the male engaging element in the region (2).
In order for the inclined engagement element and the male engagement element constituting the surface fastener of the present invention to function, an engagement element that engages with these elements is essential, and the surface on the side to be engaged has a plurality of loop shapes. A loop surface fastener having an engagement element is preferred.
本発明の面ファスナーを係合させるループ面ファスナーは、係合させる側の面に複数のループ状係合素子を有する。該ループ状係合素子は、例えば、合成繊維のマルチフィラメントから形成することができる。該合成繊維のマルチフィラメントの太さ（単繊維繊度）としては、２〜６０ｄｔｅｘの範囲内であることが好ましく、１０〜３０ｄｔｅｘの範囲内であることがより好ましい。また、合成繊維のマルチフィラメントとしては合成繊維の単糸を２〜５０本まとめたものを使用することができる。上記合成繊維のマルチフィラメントを構成する素材としては、例えば、ポリアミド、ポリエステル、ポリアクリロニトリル、ポリオレフィン等が挙げられる。 The loop surface fastener for engaging the surface fastener of the present invention has a plurality of loop-shaped engaging elements on the surface on the side to be engaged. The loop-like engagement element can be formed from, for example, a multifilament of synthetic fibers. The thickness (single fiber fineness) of the multifilament of the synthetic fiber is preferably in the range of 2 to 60 dtex, and more preferably in the range of 10 to 30 dtex. In addition, as a multifilament of synthetic fibers, 2 to 50 synthetic fiber single yarns can be used. Examples of the material constituting the multifilament of synthetic fiber include polyamide, polyester, polyacrylonitrile, and polyolefin.
前記複数のループ状係合素子のループ高さは、０．５ｍｍ以上３．０ｍｍ以下であることが必要である。ループ高さが０．５ｍｍより小さいと係合力が乏しく、係合によるせん断力が発現することが困難となり、一方、ループ高さが３．０ｍｍより大きいと面ファスナー間のズレが生じ易くなったり、せん断力が変動したりする。
係合力の安定性の観点から、ループ面ファスナー部材におけるループ高さは、０．８ｍｍ以上２．５ｍｍ以下であることが好ましく、１．２ｍｍ以上２．０ｍｍ以下であることがより好ましい。なお、前記ループ高さは実施例の項目において後述する方法により測定することができる。The loop height of the plurality of loop-like engagement elements needs to be 0.5 mm or more and 3.0 mm or less. When the loop height is smaller than 0.5 mm, the engagement force is poor, and it is difficult to develop a shearing force due to the engagement. On the other hand, when the loop height is larger than 3.0 mm, the gap between the hook-and-loop fasteners tends to occur. The shearing force fluctuates.
From the viewpoint of the stability of the engagement force, the loop height of the loop surface fastener member is preferably 0.8 mm or more and 2.5 mm or less, and more preferably 1.2 mm or more and 2.0 mm or less. In addition, the said loop height can be measured by the method mentioned later in the item of an Example.

このテープ状成形面ファスナー（傾斜係合素子列：幅×長さ（図１０のＴ方向）５０ｍｍ×４０ｍｍと鏃状雄型係合素子：幅×長さ（図１０のＴ方向）５０ｍｍ×１０ｍｍ）を長さ方向と垂直方向に長さ５ｃｍ（幅５０ｍｍ）に切断し、係合力と剥離音を測定したところ、係合力［せん断（シアー）強力］は３２．５ｋｇ／係合面積であり、剥離音は、初回：７９ｄＢ、１０回：７７ｄＢ、２０回：７７ｄＢ、３０回：７６ｄＢであった。
この成形面ファスナーは、上記の実施例１〜６で製造した面ファスナーのように傾斜係合素子面ファスナーと鏃状雄型係合素子面ファスナーを縫製一体化する必要がなく、一挙に両者が存在している面ファスナーが製造できることから、製造が容易でかつ安価に製造でき、しかも、縫製した場合に生じやすいミシン目からの面ファスナーの裂断という問題を有さず、特に優れたものである。
そして、この成形面ファスナーを用いて上記実施例と同様に腰痛ベルトに使用したところ、着脱が極めて容易で問題なく使用でき、具体的な使用においても、適度の締め付け感を有していることから着用者に安定感を与え、着用中に身体を大きく動かしても係合が外れることがなく、極めて優れたものであった。This tape-shaped molded surface fastener (inclined engagement element array: width × length (T direction in FIG. 10) 50 mm × 40 mm and bowl-shaped male engagement element: width × length (T direction in FIG. 10) 50 mm × 10 mm ) Was cut to a length of 5 cm (width 50 mm) in the direction perpendicular to the length direction, and the engagement force and peeling noise were measured. The engagement force [shear (shear) strength] was 32.5 kg / engagement area. The peeling sound was first time: 79 dB, 10 times: 77 dB, 20 times: 77 dB, 30 times: 76 dB.
This molded surface fastener does not need to integrally integrate the inclined engagement element surface fastener and the hook-shaped male engagement element surface fastener as in the surface fasteners manufactured in Examples 1 to 6 above. Since the existing surface fastener can be manufactured, it can be manufactured easily and inexpensively, and it does not have the problem of tearing of the surface fastener from the perforation that is likely to occur when sewing. is there.
And when using this molded surface fastener for a low back pain belt as in the above example, it is extremely easy to attach and detach and can be used without problems, and even in specific use it has a moderate tightening feeling. The wearer was given a sense of stability, and even when the body was moved greatly during wearing, the engagement was not disengaged, and it was extremely excellent.
表１の評価結果から、実施例１〜７においては、腰痛ベルトの着用評価において意図しない剥離（外れ）を防止できる。
また、実施例３と実施例４の対比より、せん断（シアー）係合力の点から、雄型係合素子領域（２）は端部側に配置した方が良いことが示唆される。
さらに、実施例５の結果から、雄型係合素子領域（２）を上下配置した場合では、剥離音の低減効果が得られないことが示唆される。
また、係合解除（剥離）のし易さは、傾斜係合素子領域群（１）のみからなる比較例１、及び傾斜係合素子領域群（１）比率が９０％の実施例６が容易に剥離し易いのは勿論であるが、その他では、実施例１，２が剥離し易かった。
さらに、実施例７の成形面ファスナーを用いた腰痛ベルトは、着脱が極めて容易で、着用者に適度の締め付け感と安定感を与え、極めて優れたものであった。From the evaluation results in Table 1, in Examples 1 to 7, unintended peeling (detachment) can be prevented in the evaluation of wearing the low back pain belt.
Further, the comparison between Example 3 and Example 4 suggests that the male engagement element region (2) should be disposed on the end side in terms of shear (shear) engagement force.
Furthermore, the result of Example 5 suggests that the effect of reducing the peeling noise cannot be obtained when the male engagement element region (2) is vertically arranged.
Further, the ease of disengagement (peeling) is easy in Comparative Example 1 including only the inclined engagement element region group (1) and Example 6 in which the ratio of the inclined engagement element region group (1) is 90%. Of course, Examples 1 and 2 were easily peeled off.
Furthermore, the low back pain belt using the molded surface fastener of Example 7 was extremely easy to attach and detach, giving the wearer an appropriate tightening feeling and stability, and was extremely excellent.
本発明の面ファスナーは、使用中に剥がれて外れることがなく、剥離時のバリバリという不快音が少ない面ファスナーとして、腰痛ベルト、姿勢矯正ベルト等のほか、膝装着用サポーター等の各種身体サポーターや各種ポーチ等の身体装着ベルト等や、手袋、血圧計の腕巻き部や乳幼児のおむつカバーや使い捨ておむつ等に利用できる。 The hook-and-loop fastener of the present invention is not peeled off during use, and has a low level of unpleasant noise when peeled off.In addition to a low back pain belt, posture correction belt, etc., various body supporters such as a knee-mounting supporter, It can be used for body wearing belts such as various pouches, gloves, arm winding parts of blood pressure monitors, diaper covers for infants and disposable diapers.
