Description

本考案は、布の縫合や刺繍等の手縫い作業を行うための縫い針に関する。   The present invention relates to a sewing needle for performing sewing operations such as sewing and embroidery of cloth.

手縫い作業に用いられる縫い針は、一般に、鋼線材によって構成されており、先端部には先鋭状の針先が設けられる一方、基端部には糸通し孔が設けられ、先端部と基端部の間は、略円形断面を有する直線状の本体胴部とされている。縫い針を使用する際には、糸通し孔に糸を通した状態で運針を行い、布の縫合、刺繍、キルティング等の手縫い作業を行う。なお、一般用途向けの縫い針においては、防錆のために、たとえば鋼線材表面がニッケルメッキなどの銀白色系のメッキ膜によって覆われる場合がある。この場合、メッキ膜の形成後に表面研磨処理を施すことにより、表面平滑性の向上が図られる。   Sewing needles used for hand-sewing operations are generally made of steel wire, and a sharp needle tip is provided at the distal end portion, while a threading hole is provided at the proximal end portion, and the distal end portion and the proximal end portion are provided. A space between the two parts is a linear main body having a substantially circular cross section. When using a sewing needle, the needle is moved while the thread is passed through the threading hole, and hand sewing operations such as sewing, embroidery, and quilting are performed. In addition, in a sewing needle for general use, for example, the surface of a steel wire may be covered with a silver-white plating film such as nickel plating for rust prevention. In this case, surface smoothness is improved by performing a surface polishing treatment after the formation of the plating film.

手縫い用の縫い針については、縫い作業の作業性向上の観点から、種々の改良が施されている。たとえば、布地に対する針の通りやすさ(布通り性)の向上を図るため、研磨あげ針と呼称される縫い針が知られている(たとえば非特許文献1を参照)。この研磨あげ針においては、針の先端部から本体胴部にかけての外周に、本体胴部が延びる方向に沿った研磨溝が形成されている。このような構成の縫い針によれば、布地に対する先端部ないし本体胴部の接触面積が減少することによって、針と布地との間の摩擦抵抗が低下し、その結果、布通り性がよくなると考えられている。   Various improvements have been made to the sewing needle for hand-sewing from the viewpoint of improving the workability of the sewing work. For example, a sewing needle called a polishing needle is known in order to improve the ease of passing a needle (cloth passing property) with respect to a fabric (see, for example, Non-Patent Document 1). In this polishing needle, a polishing groove is formed on the outer periphery from the tip of the needle to the main body barrel along the direction in which the main body barrel extends. According to the sewing needle having such a configuration, the frictional resistance between the needle and the fabric is reduced by reducing the contact area of the front end portion or the body trunk portion with respect to the fabric. It is considered.

そして、この研磨あげ針については、布通り性を重視する観点から、通常、メッキ処理を施していない。この理由としては、仮に、研磨あげ針にメッキ処理を施したとしても、メッキ膜の表面が粗面となって布通り性が悪くなり、さらに表面研磨処理を施したとしても、布地に対する先端部ないし本体胴部の接触面積が増大し、布通り性が実質的に悪くなると考えられるからである。   The polishing needle is usually not subjected to plating from the viewpoint of emphasizing cloth passing. The reason for this is that even if the polishing needle is plated, the surface of the plating film becomes rough and the cloth penetration becomes worse. Or it is because the contact area of a main-body trunk | drum increases, and it is thought that cloth penetration property deteriorates substantially.

しかしながら、上記構成の縫い針(研磨あげ針)においては、メッキ膜を施していないため、防錆性が不充分であり、外観品位を適切に維持するのが困難であった。   However, since the sewing needle (polishing needle) having the above-described configuration is not provided with a plating film, the antirust property is insufficient and it is difficult to maintain the appearance quality appropriately.

「クロバー製品カタログ 2008−2009」、2008年2月発行、p.6“Clover Product Catalog 2008-2009”, February 2008, p. 6

本考案は、このような事情のもとで考え出されたものであって、先端部および本体胴部の外周に研磨溝が形成された縫い針において、布通り性が良好で、かつ防錆性に優れた縫い針を提供することを課題とする。   The present invention has been conceived under such circumstances, and in a sewing needle in which a polishing groove is formed on the outer periphery of the front end portion and the main body trunk portion, the cloth passing property is good and rust prevention is provided. An object is to provide a sewing needle excellent in properties.

上記の課題を解決するため、本考案では、次の技術的手段を講じている。   In order to solve the above problems, the present invention takes the following technical means.

本考案によって提供される縫い針は、先鋭状の針先を有する先端部と、直線状に延びる本体胴部と、糸通し孔を有する基端部とを備え、上記先端部および上記本体胴部の外周には、上記本体胴部が延びる方向に沿って研磨溝が形成された縫い針であって、上記先端部および上記本体胴部を覆う黒ニッケルメッキ膜を有することを特徴としている。   The sewing needle provided by the present invention includes a distal end portion having a sharp needle tip, a main body barrel portion extending linearly, and a proximal end portion having a threading hole, and the distal end portion and the main body barrel portion. A sewing needle having a polishing groove formed along the direction in which the main body trunk extends, and has a black nickel plating film covering the tip and the main body trunk.

本考案者は、上記課題を解決するべく鋭意検討したところ、先端部および本体胴部に研磨溝が形成されたいわゆる研磨あげ針において、先端部および本体胴部を黒ニッケルメッキ膜によって覆うことにより、防錆性を高めるとともに、布通り性についても優れた特性を実現しうることを見出して本考案を完成させるに到ったものである。すなわち、従来の知見では、研磨あげ針においては、メッキ処理を施さない方が布通り性が良いと考えられていたが、本考案者は、研磨あげ針の先端部および本体胴部を黒ニッケルメッキ膜によって覆うと、メッキ処理を施していない場合と同等以上の布通り性が得られることを見出したのである。   The present inventor has intensively studied to solve the above problems, and in a so-called polishing needle in which a polishing groove is formed in the distal end portion and the main body barrel portion, the front end portion and the main body barrel portion are covered with a black nickel plating film. The inventors have found that the present invention can be completed by finding that it can improve the rust prevention property and can also realize excellent properties in terms of cloth passage. In other words, according to the conventional knowledge, it was considered that the polishing needles were better when the plating treatment was not performed. However, the present inventor considered that the tip of the polishing needle and the body barrel were made of black nickel. It was found that when covered with a plating film, the cloth passing property is equal to or higher than the case where the plating treatment is not performed.

本考案のその他の特徴および利点は、添付図面を参照して以下に行う詳細な説明によって、より明らかとなろう。   Other features and advantages of the present invention will become more apparent from the detailed description given below with reference to the accompanying drawings.

以下、本考案の好ましい実施の形態について、図面を参照して具体的に説明する。   Hereinafter, preferred embodiments of the present invention will be specifically described with reference to the drawings.

図1〜図3は、本考案に係る縫い針の一例を示している。本実施形態の縫い針Aは、先鋭状の針先11aを有する先端部11と、直線状に延びる本体胴部12と、基端部13とを備え、これらが一体につながった構成とされている。先端部11は、先鋭状の針先11aを有し、この針先11aに向けて先細り状とされている。基端部13は、偏平状とされており、厚み方向に貫通する糸通し孔13aが形成されている。縫い針Aの素材としては、たとえば鋼材硬鋼線やピアノ線などの鋼線材が好適に用いられる。   1 to 3 show an example of a sewing needle according to the present invention. The sewing needle A of the present embodiment includes a distal end portion 11 having a sharp needle tip 11a, a main body barrel portion 12 extending linearly, and a proximal end portion 13, and these are integrally connected. Yes. The distal end portion 11 has a sharp needle tip 11a and is tapered toward the needle tip 11a. The base end portion 13 has a flat shape, and is formed with a threading hole 13a penetrating in the thickness direction. As a material of the sewing needle A, for example, a steel wire material such as a hard steel wire or a piano wire is suitably used.

図1および図2によく表れているように、先端部11および本体胴部12には、本体胴部12の長手方向に沿って延びる研磨溝14が形成されている。上記研磨溝14の形成は、たとえば研磨処理によって行う。具体的には、たとえば図4に表れているように、鼓状の研磨輪21を回転させ、当該回転方向と本体胴部の長手方向とが沿うようにして、ローラ22と研磨輪21との間に針体A’を送り込むことによって研磨溝14が形成される。   As clearly shown in FIGS. 1 and 2, a polishing groove 14 extending along the longitudinal direction of the main body barrel 12 is formed in the distal end portion 11 and the main body barrel 12. The polishing groove 14 is formed by, for example, a polishing process. Specifically, for example, as shown in FIG. 4, the drum-shaped polishing wheel 21 is rotated so that the rotation direction and the longitudinal direction of the main body body are aligned, so that the roller 22 and the polishing wheel 21 are aligned. The polishing groove 14 is formed by feeding the needle body A ′ therebetween.

本実施形態においては、図3にその断面構造が表れているように、先端部11および本体胴部12を覆うメッキ層15が形成されている。メッキ層15は、下地としてのニッケルメッキ膜15Aと、黒ニッケルメッキ膜15Bとが順次積層形成されたものである。ニッケルメッキ膜15Aは、たとえば無電解ニッケルメッキ法によって形成される。黒ニッケルメッキ膜15Bは、たとえばニッケルとスズの合金、あるいはニッケルと亜鉛の合金からなり、メッキ層15の表層に位置するとともに、その外観は重量感のある黒色を呈する。上記膜15A,15Bの膜厚は、たとえば、それぞれ10μm以下程度である。   In the present embodiment, a plating layer 15 that covers the distal end portion 11 and the main body trunk portion 12 is formed so that the cross-sectional structure is shown in FIG. The plating layer 15 is formed by sequentially laminating a nickel plating film 15A as a base and a black nickel plating film 15B. The nickel plating film 15A is formed by, for example, an electroless nickel plating method. The black nickel plating film 15B is made of, for example, an alloy of nickel and tin, or an alloy of nickel and zinc. The black nickel plating film 15B is located on the surface layer of the plating layer 15 and has a heavy black appearance. The film thicknesses of the films 15A and 15B are each about 10 μm or less, for example.

本実施形態の縫い針Aは、研磨溝14が形成されたいわゆる研磨あげ針であって、メッキ層15によって覆われているため、優れた防錆性を発揮する。したがって、外観品位を適切に維持することができる。加えて、最表層に黒ニッケルメッキ膜15Bを形成したことにより、布通り性の向上が実現される。この布通り性は、たとえば、複数種類の縫い針について、同一の布地に対して針先を突き刺して本体胴部が当該布地を通過するまでゆっくり刺し込んだときに、針に加えられた最大荷重を測定することにより、評価することができる。当該最大荷重が小であるほど、布地と針との間の摩擦抵抗が小さく、布通り性に優れると判断することができる。   The sewing needle A of the present embodiment is a so-called polishing needle having a polishing groove 14 and is covered with the plating layer 15 and exhibits excellent rust prevention. Therefore, the appearance quality can be appropriately maintained. In addition, since the black nickel plating film 15B is formed on the outermost layer, improvement in the cloth passing property is realized. For example, with respect to multiple types of sewing needles, this cloth penetration is the maximum load applied to the needle when the needle tip is pierced into the same fabric and slowly inserted until the body trunk passes through the fabric. It can be evaluated by measuring. It can be determined that the smaller the maximum load is, the smaller the frictional resistance between the fabric and the needle is, and the better the cloth passing property is.

黒ニッケルメッキ膜15Bが最表層に形成された本実施形態の縫い針Aは、メッキ処理を施していない縫い針や、ニッケルメッキ膜が最表層に形成された縫い針に比べて、同等以上の布通り性が実現される。このことは、メッキ処理を施した縫い針については、さらに表面研磨処理を施さないと表面が粗面となって布通りが悪くなると考えられていることに反するが、最表層に黒ニッケルメッキ膜15Bを選択的に形成すると、布通り性に優れるといった予期しない効果が得られた。   The sewing needle A of the present embodiment in which the black nickel plating film 15B is formed on the outermost layer is equal to or greater than the sewing needle that is not plated or the sewing needle in which the nickel plating film is formed on the outermost layer. Fabrication is realized. This is contrary to the fact that the surface of the sewing needle that has been subjected to plating treatment is considered to be rough if the surface is not subjected to surface polishing treatment. When 15B was selectively formed, an unexpected effect such as excellent cloth passing properties was obtained.

以上、本考案の実施形態を説明したが、本考案の技術的範囲は上記した実施形態に限定されるものではない。本考案に係る縫い針の各部の具体的な構成は、考案の思想から逸脱しない範囲内で種々な変更が可能である。   Although the embodiment of the present invention has been described above, the technical scope of the present invention is not limited to the above-described embodiment. The specific configuration of each part of the sewing needle according to the present invention can be variously modified without departing from the concept of the invention.

以下に、本考案に関して行なった評価試験について、実施例および比較例1,2に基づいて説明する。   Below, the evaluation test performed regarding this invention is demonstrated based on an Example and Comparative Examples 1 and 2. FIG.

〔実施例〕
本実施例においては、上記実施形態に係る縫い針Aを試験体として準備して、評価試験を行なった。本実施例では、針本体としてφ0.56×39.4mm(本体胴部の直径が0.56mm、全長が39.4mm)の規格サイズのものを使用した。黒ニッケルメッキ膜15Bとしては、ニッケルとスズの合金からなるものを採用した。本実施例では、上記方法によって作製された試験体としての30本の縫い針Aを準備し、各試験体について、布に対して針先11aから約15mmの位置にある本体胴部12まで刺し込み、そのときの最大荷重(単位:グラム重)をプッシュプルゲージによって測定した。なお、本実施例で用いた布としては、平織りの綿織物からなるものを用いた。各試験体の最大荷重の測定結果を表1に示す。
〔Example〕
In this example, the sewing needle A according to the above embodiment was prepared as a test body, and an evaluation test was performed. In this example, a needle body having a standard size of φ0.56 × 39.4 mm (the diameter of the main body is 0.56 mm and the total length is 39.4 mm) was used. As the black nickel plating film 15B, a film made of an alloy of nickel and tin was adopted. In this embodiment, 30 sewing needles A as test specimens prepared by the above-described method are prepared, and each test specimen is pierced to the main body barrel 12 at a position of about 15 mm from the needle tip 11a with respect to the cloth. The maximum load (unit: gram weight) at that time was measured with a push-pull gauge. In addition, as a cloth used in this example, a cloth made of plain weave cotton fabric was used. Table 1 shows the measurement results of the maximum load of each specimen.

〔比較例1〕
本比較例では、試験体として、実施例と同様の構成を有する針本体を用いて実施例と同様の研磨溝を形成する一方、メッキ処理を施さない縫い針を準備した。本比較例の試験体は、実施例と同様にいわゆる研磨あげ針として構成されているが、実施例とは異なりメッキ膜が形成されていないものである。本比較例では、試験体としての30本の上記縫い針を準備し、各試験体について、実施例と同一の布を使用し、同一の条件で当該布に対して針先から約15mmの位置にある本体胴部まで刺し込み、そのときの最大荷重(単位:グラム重)をプッシュプルゲージによって測定した。各試験体の最大荷重の測定結果を表1に示す。
[Comparative Example 1]
In this comparative example, a polishing needle similar to that of the example was formed using a needle body having the same configuration as that of the example as a test body, while a sewing needle not subjected to plating treatment was prepared. The test body of this comparative example is configured as a so-called polishing needle as in the example, but unlike the example, a plating film is not formed. In this comparative example, 30 sewing needles as test specimens were prepared, and the same cloth as in the example was used for each specimen, and the position about 15 mm from the needle tip with respect to the cloth under the same conditions. The maximum body load (unit: gram weight) at that time was measured with a push-pull gauge. Table 1 shows the measurement results of the maximum load of each specimen.

〔比較例2〕
本比較例では、試験体として、実施例と同様の構成を有する針本体を用い、実施例とは異なり研磨溝を形成せずに、針本体にニッケルメッキ膜を形成(表面研磨処理を含む)した縫い針を準備した。本比較例の試験体は、実施例の研磨あげ針とは異なり、本体胴部が略円形断面を有する一般用途向けの縫い針である。本比較例では、試験体としての30本の上記縫い針を準備し、各試験体について、実施例と同一の布を使用し、同一の条件で当該布に対して針先から約15mmの位置にある本体胴部まで刺し込み、そのときの最大荷重(単位:グラム重)をプッシュプルゲージによって測定した。各試験体の最大荷重の測定結果を表1に示す。
[Comparative Example 2]
In this comparative example, a needle body having the same configuration as that of the example is used as a test body, and unlike the example, a nickel plating film is formed on the needle body without forming a polishing groove (including surface polishing treatment). A prepared sewing needle was prepared. The test body of this comparative example is a sewing needle for general use in which the main body has a substantially circular cross section, unlike the polishing needle of the embodiment. In this comparative example, 30 sewing needles as test specimens were prepared, and the same cloth as in the example was used for each specimen, and the position about 15 mm from the needle tip with respect to the cloth under the same conditions. The maximum body load (unit: gram weight) at that time was measured with a push-pull gauge. Table 1 shows the measurement results of the maximum load of each specimen.

Figure 0003146858
Figure 0003146858

表1に示す実施例の最大荷重の平均値と、比較例1の最大荷重の平均値とを比較すると、実施例における縫い針Aでは、最大荷重の平均値が約8%小さかった。これにより、 黒ニッケルメッキ膜15Bを施した縫い針Aは、メッキ処理を施さない研磨あげ針(比較例1)に比べて、布通り性に優れることが判明した。また、実施例の最大値と最小値との差、および比較例1の最大値と最小値との差を比較すると理解できるように、 実施例は比較例1に比べて試験体ごとのばらつきが小さく、品質面においても安定していることが判明した。なお、表1から分るように、研磨あげ針とは異なる一般用途向けの縫い針(比較例2)においては、研磨あげ針(実施例および比較例1)に比べて、布通り性が大幅に劣る。   When the average value of the maximum load of the example shown in Table 1 and the average value of the maximum load of the comparative example 1 were compared, the average value of the maximum load was about 8% smaller with the sewing needle A in the example. As a result, it was found that the sewing needle A provided with the black nickel plating film 15B was superior in the cloth passing property compared to the polishing needle (Comparative Example 1) not subjected to the plating treatment. Further, as can be understood by comparing the difference between the maximum value and the minimum value of the example, and the difference between the maximum value and the minimum value of the comparative example 1, the example has a variation from specimen to specimen as compared with the comparative example 1. It was found to be small and stable in terms of quality. As can be seen from Table 1, the sewing needle for general use (Comparative Example 2), which is different from the polishing needle, has significantly greater cloth passage than the polishing needle (Example and Comparative Example 1).
