Abstract
Description
本発明は、面ファスナーに関し、さらに詳しくは面ファスナーを剥離する際に生ずる剥離音の小さい減剥離音面ファスナーに関する。 The present invention relates to a hook-and-loop fastener, and more particularly, to a reduced-release sound surface fastener that generates a small amount of peeling sound when peeling the hook-and-loop fastener.
係止部材として広く使用されている面ファスナーは、かぎ状あるいはキノコ状のフック状係合素子を基布の一面に立設したフック面ファスナーと、該フック状係合素子と係合するループ状あるいはアーチ状の係合素子を基布の一面に立設したループ面ファスナーから構成され、この両者を圧接することにより係合し、該面ファスナーを取付けた被着体を一体的に接合固定するものである。
また、フック状係合素子とループ状係合素子とを基布の一面に混在させたフック・ループ混在型面ファスナーも知られており、同一構造の面ファスナーを圧接して、面ファスナーを係合することができる。
このような面ファスナーは、着脱が容易なことから衣料や手袋、靴類、鞄等の開閉部の止め具として、また列車、飛行機、バス等に多数備えられた座席のシートカバー、さらには寝具シートカバー等の取付け具として広く使用されている。
A hook-and-loop fastener that is widely used as a locking member is a hook-shaped fastener that has a hook-like or mushroom-like hook-like engagement element standing on one surface of a base fabric, and a loop shape that engages with the hook-like engagement element. Or it is comprised from the loop surface fastener which stood up the arch-like engagement element on the one surface of the base fabric, it engages by press-contacting both, and the to-be-adhered body which attached this surface fastener is integrally joined and fixed. Is.
There is also known a hook / loop mixed surface fastener in which hook-like engagement elements and loop-like engagement elements are mixed on one surface of a base fabric. Can be combined.
Such hook-and-loop fasteners are easy to put on and take off, so they are used as stoppers for opening and closing parts of clothing, gloves, shoes, bags, etc., seat covers for seats provided in many trains, airplanes, buses, etc. Widely used as a fixture for seat covers and the like.
ところで、係合した面ファスナー、特に布製面ファスナーを剥がす際に、バリバリという大きな剥離音が発生し、この不快な剥離音の低減が求められている。
そこで、かかる剥離音を抑制する面ファスナーの提案が種々なされている。例えば、剥離音低減のために、係合素子が立設する基布または基布の裏面に付設する部材の見かけ密度を０．５ｇ／ｃｍ３以下として、この疎な部分で振動を減衰させ、剥離音を低減させた面ファスナーが開示されている。（特許文献１〜３参照）。
しかしながら、かかる低密度の部材を面ファスナーに付与した構造では減音効果が充分でなく、また衣料等の被着体への縫い付けが困難になるという問題点が指摘されていた。
By the way, when peeling the engaged surface fastener, especially the cloth surface fastener, a large peeling noise called burr is generated, and there is a need to reduce this unpleasant peeling noise.
Then, the proposal of the surface fastener which suppresses this peeling sound is made | formed variously. For example, in order to reduce the peeling noise, the apparent density of the base fabric on which the engagement element is erected or the member attached to the back surface of the base fabric is 0.5 g / cm 3 or less, and the vibration is attenuated in this sparse part, A hook-and-loop fastener with reduced peeling noise is disclosed. (See Patent Documents 1 to 3).
However, it has been pointed out that the structure in which such a low-density member is applied to a hook-and-loop fastener does not have a sufficient sound reduction effect, and that it is difficult to sew an adherend such as clothing.
本発明は、上記した問題を解決するものであり、その目的は、衣料等の被着体への仮止め位置の決定が容易にでき、さらに縫製にて強固に取付けることができ、しかも面ファスナーの剥離音を低減する実用性に優れた減剥離音面ファスナーを提供することにある。 The present invention solves the above-described problems, and its purpose is to facilitate determination of a temporary fixing position on an adherend such as clothing, and to attach firmly by sewing, and to make a hook-and-loop fastener. An object of the present invention is to provide a reduced peeling sound surface fastener that is excellent in practicality for reducing the peeling noise.
すなわち本発明は、基布の表面に多数の係合素子を有し、該基布の裏面に粘着剤層を有する面ファスナーであって、該粘着剤層の密度が０．８〜１．３ｇ／ｃｍ３、厚さが０．３〜１．０ｍｍであることを特徴とする減剥離音面ファスナーである。 That is, the present invention is a hook-and-loop fastener having a number of engaging elements on the surface of the base fabric and an adhesive layer on the back surface of the base fabric, the density of the adhesive layer being 0.8 to 1.3 g. / Cm 3 and a thickness of 0.3 to 1.0 mm.
本発明により、被着体への仮止めが容易にでき、縫製での取付けが容易となり、さらに剥離音を低減させた面ファスナーを得ることができる。 According to the present invention, temporary fastening to an adherend can be easily performed, attachment by sewing is facilitated, and a hook-and-loop fastener with reduced peeling noise can be obtained.
本発明で使用される面ファスナーは、フック状係合素子またはループ状係合素子を基布一面に立設した面ファスナー部材、あるいはフック状係合素子とループ状係合素子とを基布の同一面に立設したフック・ループ混在型面ファスナーである。フック状係合素子としては、かぎ状係合素子またはキノコ状係合素子のいずれでもよいが、適度な係合強度の確保、係合素子の耐久性の点からかぎ状係合素子が好ましい。
一方、ループ面ファスナーとしては、マルチフィラメントループを基布に製編織したもの、またはループ状繊維やアーチ状繊維を有する不織布のいずれでもよい。これらの面ファスナーは、構成繊維を固定するために、バックコート剤を用いることができる。従来のバックコート剤は粘度が低く、繊維間に浸透し極めて薄い樹脂膜を生成するものであり、後述する本発明の粘着剤層とは別のものである。
さらに近年は、自己融着性の繊維を含み該融着性繊維の融着により繊維を固定する面ファスナー、すなわちバックコート剤を必要としないタイプの面ファスナーも開発されており、かかる融着面ファスナーも本発明に好適に使用される。
The surface fastener used in the present invention includes a hook-and-loop engaging element or a loop-shaped engaging element that is erected on one surface of the base fabric, or a hook-shaped engaging element and a loop-shaped engaging element. It is a hook and loop mixed surface fastener standing upright on the same surface. The hook-like engagement element may be either a hook-like engagement element or a mushroom-like engagement element, but a hook-like engagement element is preferable from the viewpoint of securing an appropriate engagement strength and durability of the engagement element.
On the other hand, the loop surface fastener may be either a knitted or woven multifilament loop on a base fabric, or a non-woven fabric having loop-like fibers or arch-like fibers. These hook-and-loop fasteners can use a backcoat agent to fix the constituent fibers. A conventional backcoat agent has a low viscosity and penetrates between fibers to form an extremely thin resin film, which is different from the adhesive layer of the present invention described later.
Furthermore, in recent years, surface fasteners that contain self-bonding fibers and fix the fibers by fusing the fusible fibers, that is, a type of surface fastener that does not require a back coat agent have been developed. Fasteners are also preferably used in the present invention.
本発明の面ファスナーを構成する素材としては、ポリアミド系、ポリエステル系、ポリオレフィン系等の熱可塑性繊維が通常使用される。衣料用に用いる場合は、風合面に優れることからポリアミド系繊維が好ましい。
係合素子および基布を含む面ファスナー自体の厚みは１〜４ｍｍが好ましく、接合時の厚みを小さくするためには、１．５〜２．５ｍｍがより好ましい。
As the material constituting the surface fastener of the present invention, thermoplastic fibers such as polyamide, polyester and polyolefin are usually used. When used for clothing, polyamide-based fibers are preferred because of their excellent hand feeling.
The thickness of the surface fastener itself including the engagement element and the base fabric is preferably 1 to 4 mm, and more preferably 1.5 to 2.5 mm in order to reduce the thickness at the time of joining.
フック状係合素子に使用されるモノフィラメントの糸径は、０．１〜０．３ｍｍが好ましく、係合力保持の点から０．１２〜０．２５ｍｍがより好ましく、さらに好ましくは、０．１４〜０．１８ｍｍである。また、フック密度は、５０〜１３０ケ／ｃｍ２が好ましい。
ループ状係合素子は、１００〜４００ｄｔｅｘ／５〜５０ｆのマルチフィラメントが好適に使用され、風合、係合耐久面から１１０〜３００ｄｔｅｘ／１０〜３０ｆが好ましい。さらに好ましくは、１２０〜２００ｄｔｅｘ／１５〜２５ｆである。また、ループ密度は５０〜１３０ケ／ｃｍ２が好ましい。
The yarn diameter of the monofilament used for the hook-like engaging element is preferably 0.1 to 0.3 mm, more preferably 0.12 to 0.25 mm, and still more preferably 0.14 to 0.25 mm from the viewpoint of maintaining the engaging force. 0.18 mm. The hook density is preferably 50 to 130 pieces / cm 2 .
As the loop-shaped engagement element, a multifilament of 100 to 400 dtex / 5 to 50 f is preferably used, and 110 to 300 dtex / 10 to 30 f is preferable in terms of texture and engagement durability. More preferably, it is 120-200 dtex / 15-25f. The loop density is preferably 50 to 130 / cm 2 .
本発明の面ファスナーに設ける粘着剤層は、密度が０．８〜１．３ｇ／ｃｍ３、より好ましくは０．９〜１．０ｇ／ｃｍ３であり、その厚みは、０．３〜１．０ｍｍ、より好ましくは０．４〜０．８ｍｍである。また、該粘着剤層を構成する粘着剤の組成は、アクリル酸エステルを主モノマーとし、アクリル酸に代表される極性モノマーを共重合させたアクリル系樹脂からなる感圧接着性粘着剤や、天然ゴム、ＳＢＲ、ＩＲを主体とし、粘着性付与樹脂、軟化剤、充填剤等を配合してなるゴム系の感圧性接着性粘着剤等の感圧性接着剤が使用できる。アクリル系感圧性接着剤は、ゴム系感圧性接着剤に比して耐候性、耐久性に優れるという利点がある。該粘着剤層は、芯材として不織布や織布が挿入されたものでもよい。芯材を有する粘着剤層は、粘着剤層の強度を高める効果のほかに、予め用意した粘着剤を面ファスナー裏面へ接合する作業を容易にできる利点がある。該粘着剤は面ファスナーの裏面に直接塗布し、粘着剤層を形成させる。
従来の面ファスナーにおいても、仮止め用の粘着剤層を裏面に有するものがあるが、その厚さは薄く、通常０．１ｍｍ程度である。減剥離音の効果を得るには、０．３ｍｍ以上の層が必要である。
The pressure-sensitive adhesive layer provided on the surface fastener of the present invention has a density of 0.8 to 1.3 g / cm 3 , more preferably 0.9 to 1.0 g / cm 3 , and a thickness of 0.3 to 1 0.0 mm, more preferably 0.4 to 0.8 mm. In addition, the composition of the pressure-sensitive adhesive constituting the pressure-sensitive adhesive layer includes a pressure-sensitive adhesive pressure-sensitive adhesive composed of an acrylic resin in which an acrylic ester is a main monomer and a polar monomer typified by acrylic acid is copolymerized, and natural Pressure-sensitive adhesives such as rubber-based pressure-sensitive adhesives, which are mainly composed of rubber, SBR, and IR, and are blended with tackifying resins, softeners, fillers and the like can be used. Acrylic pressure sensitive adhesives have the advantage of superior weather resistance and durability compared to rubber pressure sensitive adhesives. The pressure-sensitive adhesive layer may be one in which a nonwoven fabric or a woven fabric is inserted as a core material. In addition to the effect of increasing the strength of the pressure-sensitive adhesive layer, the pressure-sensitive adhesive layer having a core material has an advantage of facilitating the operation of joining a pressure-sensitive adhesive prepared in advance to the surface fastener back surface. The pressure-sensitive adhesive is applied directly to the back surface of the surface fastener to form a pressure-sensitive adhesive layer.
Some conventional hook-and-loop fasteners also have a temporary adhesive layer on the back surface, but the thickness is thin, usually about 0.1 mm. In order to obtain the effect of reduced peeling sound, a layer of 0.3 mm or more is necessary.
本発明において、面ファスナーの剥離音は、ＪＩＳ Ｚ８７３１に準じて測定される。
騒音計（リオン社製、「ＮＡ−２０」）を用い、周波数特性Ａ、動特性ＡＳＴに設定する。被着体に粘着させた５ｃｍ×５ｃｍの面ファスナー同士を係合して、面ファスナーと騒音計の測定間距離を１０ｃｍとし、剥離時の騒音計の指示値を読み取る。
剥離時の音の大きさは、ｄＢ（デシベル）で表され、人間の聴覚では、１０ｄＢの違いを約２倍の音量差として感じる。
上記サイズの面ファスナーを手袋、鞄等に縫製した試料で剥離音を測定すると、各々７５ｄＢ、８４ｄＢ程度であった。一方、本発明の粘着剤層を有しない従来の面ファスナーの剥離音は各々８４ｄＢ、９３ｄＢ程度であり、本発明の面ファスナーの剥離音は、約１０ｄＢ小さいことがわかる。
In this invention, the peeling sound of a hook_and_loop | surface fastener is measured according to JISZ8731.
Using a sound level meter ("NA-20" manufactured by Rion Co., Ltd.), the frequency characteristic A and the dynamic characteristic AST are set. 5 cm × 5 cm hook-and-loop fasteners adhered to the adherend are engaged with each other, the distance between the hook-and-loop fastener and the sound level meter is set to 10 cm, and the indicated value of the sound level meter at the time of peeling is read.
The loudness at the time of peeling is expressed in dB (decibel), and human hearing feels a difference of 10 dB as a volume difference of about twice.
When the peeling sound was measured with a sample obtained by sewing the surface fastener of the above size onto a glove, a heel or the like, it was about 75 dB and 84 dB, respectively. On the other hand, the peeling sounds of the conventional surface fastener without the adhesive layer of the present invention are about 84 dB and 93 dB, respectively, and it can be seen that the peeling sound of the surface fastener of the present invention is about 10 dB lower.
