Description
本発明は主として溶接用ワイヤーの如きワイヤーの表面に添加された油の過剰部分を拭き取り、表面の油を均一化するのに使用されるワイヤー用ワイピング不織布に関するものである。 The present invention mainly relates to a wiping nonwoven fabric for wire used for wiping off an excess portion of oil added to the surface of a wire such as a welding wire and making the surface oil uniform.
溶接用ワイヤーは表面の酸化防止,潤滑のために油(パーム油)等を付与することが必要である。このワイヤーの表面処理はワイヤーに油を添加し、この油の過剰部分を拭き取り、表面の油を均一にすることであるが、従前においてはワイヤー表面に固体潤滑剤を混合した液体潤滑剤を付着させる方法(例えば特許文献1参照)や有機モリブデンを含有させた液体潤滑剤を付着させる方法(例えば特許文献2参照)の如く潤滑剤の付着方法が提案されていることが多く、油の過剰部分の拭き取りについては殆ど触れられていない。油の過剰部分のふき取りは現在、一般的に不織布が用いられ、走行中のワイヤーに油を添加してその表面を一対の不織布に挟んで余分な油を拭き取ると同時に表面の油の均一を行っている。しかし、現在用いられている不織布はワイヤーに油を付与する過程で不織布がたるみ(皺)やよれを起こしたり表面油斑が生じたり、ワイヤーにより不織布自身が剥離することが起こり、十分なものとは云えなかった。
本発明は上述の如き実状に対処し、特にワイヤーに油を均一に付与するための不織布の構成ならびに特性に付いて検討を加え、ワイヤー表面処理中に生じるめくれ(不織布の皺)や不織布自身の剥離を抑制した不織布を提供することを目的とするものである。 The present invention addresses the actual situation as described above, and in particular, examines the configuration and characteristics of the nonwoven fabric to uniformly apply oil to the wire, and turns the nonwoven fabric (woven fabric wrinkles) and the nonwoven fabric itself during the wire surface treatment. It aims at providing the nonwoven fabric which suppressed peeling.
即ち、上記目的に適合する本発明ワイピング不織布の特徴は、スパンボンド不織布の如き長繊維からなる基材に疎水性短繊維と親水性短繊維を混繊して得た短繊維層を積層し、ニードル加工して一体化して後に樹脂接着して得た不織布であって、初期伸張弾性率が4000〜7500N/50mm/100%で、0.5mm圧縮時応力が2.0〜10.0N/cm2/0.5mm、揚油高さが1.0cm以上である特性を有することからなる。 That is, the characteristic of the wiping nonwoven fabric of the present invention that meets the above purpose is that a short fiber layer obtained by mixing hydrophobic short fibers and hydrophilic short fibers is laminated on a substrate made of long fibers such as a spunbond nonwoven fabric, Non-woven fabric obtained by needle processing and integration and then resin-bonding, initial tensile elastic modulus is 4000-7500 N / 50 mm / 100%, 0.5 mm compression stress is 2.0-10.0 N / cm 2 / 0.5 mm, and the oil pumping height is 1.0 cm or more.
ここで上記積層体不織布は目付質量が80〜300g/m2で、厚さが1.5〜3.0mmの範囲であることが好ましい。また、短繊維層は使用する疎水性繊維がポリエステル繊維、親水性繊維がレーヨン繊維であって、その混繊比率が90/10〜40/60の範囲であることが実用的である。また、接着樹脂はアクリル系又は酢酸ビニル・アクリル系を主体とした樹脂が最も一般的であり、目付質量20〜60g/m2の範囲で使用するのが好適である。 Here, the laminate nonwoven fabric preferably has a basis weight of 80 to 300 g / m 2 and a thickness of 1.5 to 3.0 mm. In the short fiber layer, it is practical that the hydrophobic fibers used are polyester fibers and the hydrophilic fibers are rayon fibers, and the mixing ratio thereof is in the range of 90/10 to 40/60. The adhesive resin is most commonly an acrylic resin or a vinyl acetate / acrylic resin, and is preferably used in a mass range of 20 to 60 g / m 2 .
上記本発明ワイピング不織布は基材として長繊維基材を用いているため、短繊維抜けや毛羽発生が起こらず、ワイヤー表面の品質を阻害することも起こることがない効果を有すると共に、親水性繊維を所要範囲混繊していることによりバインダー樹脂の分散、繊維層間の接着を均一化せしめることができ、また上記各特性を具備せしめることによりワイヤーを挟んだ不織布の特性を十分発揮することが可能となり、不織布で挟まれたワイヤーの走行中に起こる不織布のよれ、たるみや剥離をなくし、均一な油の付与を行い、油の荷重部分の拭き取りを良好ならしめる効果を有している。 Since the above-mentioned wiping nonwoven fabric of the present invention uses a long fiber base material as a base material, there is an effect that short fiber missing and fluff generation do not occur, and the quality of the wire surface is not hindered. By mixing the required range, the dispersion of the binder resin and the adhesion between the fiber layers can be made uniform, and by providing each of the above characteristics, the characteristics of the nonwoven fabric sandwiching the wires can be fully exhibited. Thus, there is an effect of eliminating sag, sag or peeling of the nonwoven fabric that occurs during the running of the wire sandwiched between the nonwoven fabrics, applying uniform oil, and wiping off the oil load.
以下、更に本発明の具体的形態について詳述する。 Hereinafter, specific embodiments of the present invention will be described in detail.
本発明に係るワイピング不織布はワイヤー表面の油剤を均一化して余剰油を拭き取り、余分な油を吸い取る役割を有するものであり、そのためワイヤーを一対の不織布に挟んで(一般には把持長さは70mm程度,線速度600mpm)ワイヤーに添加された油をワイヤー表面に均一に延ばし、余分な油を不織布内に吸収する。 The wiping nonwoven fabric according to the present invention has a role of making the oil agent on the surface of the wire uniform and wiping off excess oil and absorbing excess oil. Therefore, the wire is sandwiched between a pair of nonwoven fabrics (generally the gripping length is about 70 mm). , Linear velocity 600 mpm) The oil added to the wire is evenly spread on the wire surface, and excess oil is absorbed into the nonwoven fabric.
図1は上記本発明に係るワイピング不織布の構成の1例を示す概要図、図2は同不織布を一対使用した油均一化処理状態を示す説明図である。これら図において、1は長繊維よりなる基材、2は油の吸着能を有する短繊維層を示し、これら基材1と短繊維層2を積層し、ニードル加工で一体化した後、接着樹脂3で接着することにより本発明不織布が構成されている。そして、上記不織布Aは図2に示す如く一対の不織布の間にワイヤー4を挟み込んで表面処理に付せられるが、このとき互いに基材1側を対向させて基材1間にワイヤー4を挟み込むようにする。短繊維層側を直接ワイヤーに接触させると繊維の毛羽立ちを生じる恐れがある。
FIG. 1 is a schematic view showing an example of the configuration of the wiping nonwoven fabric according to the present invention, and FIG. 2 is an explanatory view showing a state of oil homogenization using a pair of the nonwoven fabric. In these figures, 1 is a base material made of long fibers, 2 is a short fiber layer having an oil adsorbing ability, these
ここで、上記不織布を構成する基材1は長繊維不織布であることが好ましく、短繊維ではワイヤーに接するところで短繊維抜けや毛羽を発生し、ワイヤー表面の品質を損なうことになるので好ましくない。一般に基材はポリエステルのスパンボンド不織布が用いられ、不織布の目付質量範囲としては20〜50g/m2が好ましい。目付質量範囲が20g/m2未満では薄いためにワイヤーとの接触が不均一となり易く、目付質量が50g/m2を超えるとワイヤーとの接触は問題はないが、余分な油の吸収が遅くなるのでワイヤー表面の油不均一を起こすので好ましくない。
Here, the
一方、基材1に積層される短繊維層2は、短繊維層内の接着を良好ならしめるため疎水性繊維と、親水性繊維の混繊であることが効果的である。疎水性繊維としては汎用合成繊維であれば特に限定されないが、一般にポリエステル繊維が用いられ、親水性繊維としてはレーヨン,ビニロン繊維が挙げられ、特にレーヨン繊維が好適である。
On the other hand, it is effective that the
これら短繊維層2における繊維の繊度は特に限定されないが、0.5〜10デシテックス(dtex)の範囲が好適である。そして、疎水性繊維と親水性繊維との混繊においてその混繊比率は90/10〜40/60の範囲、好ましくは80/20〜50/50がよく、親水性繊維が10未満であるとバインダーの分散が不十分となり、短繊維層内の繊維間の接着が不均一となり易くなるので好ましくなく、また、親水性繊維が60を超えるとバインダー量に対して親水性接着繊維の量が多くなり、バインダーの分布が不均一となり易いので、その結果、短繊維層内の繊維間の接着が不均一となり易くなるので好ましくない。
The fineness of the fibers in these
また、上記混繊による短繊維層の目付質量は40〜190g/m2の範囲が好適である。目付質量が40g/m2未満であると不織布の必要特性を得ることが難しく、また油吸収能が低下するので好ましくなく、また、目付質量が190g/m2を超えると不織布の特性は十分に確保できるが過剰性能となる。またコストの面でも好ましくない。 Also, the basis weight mass of short fiber layer of the above fiber-mixing is preferably in the range of 40~190g / m 2. If the mass per unit area is less than 40 g / m 2 , it is difficult to obtain the necessary properties of the nonwoven fabric, and the oil absorption capacity is lowered, which is not preferable. If the mass per unit area exceeds 190 g / m 2 , the characteristics of the nonwoven fabric are sufficient. Can be secured, but excessive performance. Moreover, it is not preferable also in terms of cost.
そして、上記基材1と短繊維層2はワイピング不織布として使用するにあたり、両者を積層しただけでは走行するワイヤーによって不織布が剪断応力を受けて層間剥離を生じ、容易に層ずれを起こすので、これを防ぐため一体化処理することが必要である。
When the
そこで、一体化のためにニードル加工による交絡処理と樹脂接着が行なわれるが、何れか一方だけで接着したのでは不充分であるので両者が併用される。この両者の併用により強い接着が可能となり、層間の剥離を起こしにくくすることができる。 Therefore, for the purpose of integration, entanglement processing by needle processing and resin bonding are performed. However, since it is not sufficient to bond only one of them, both are used together. The combination of both enables strong adhesion and makes it difficult to cause delamination between layers.
なお、ニードル加工は基布(スパンボンド不織布)に積層した短繊維層に短繊維層からスパンボンド不織布へニードル針で交絡処理をすることによって行なわれ、交絡の度合いは針深さと針密度で調節する。 Needle processing is performed by tangling the short fiber layer laminated to the base fabric (spunbond nonwoven fabric) from the short fiber layer to the spunbond nonwoven fabric with a needle needle, and the degree of entanglement is adjusted by the needle depth and needle density. To do.
一方、樹脂接着3は特に基布1(スパンボンド不織布)と短繊維層2をニードル加工で一体化した後、繊維間の接着を行なう。バインダー(樹脂)としては酢酸ビニル系やアクリル系の樹脂が好適であり、撥油性のバインダーは好ましくない。繊維構成として親水性繊維が混繊比率で10〜60の範囲であると繊維層内のバインダーの均一性を高めるので好ましい。樹脂の付着量は20〜60g/m2の範囲が好適であり、付着量が20g/m2未満であると単繊維間の接着が不充分となり、付着量が60g/m2を超えると逆に樹脂量が多くなり不織布を硬くするので何れも好ましくない。
On the other hand, in the resin bonding 3, the base fabric 1 (spunbond nonwoven fabric) and the
かくして、以上を総合し、本発明ワイピング不織布は先ず、基材1に疎水性繊維と親水性繊維からなる短繊維層2を積層し、ニードル加工により一体化した後、樹脂接着してなる不織布よりなることを第1の要件とする。この場合、上記積層体不織布は目付質量が80〜300g/m2で、厚さが1.5〜3.0mmの範囲であることが好ましい。そして、本発明は上記不織布にもとづいて更にワイヤーのワイピング用として使用するに適した特性を見出したことを第2の要件とするものである。
Thus, by combining the above, the wiping nonwoven fabric of the present invention is a nonwoven fabric obtained by first laminating a
即ち、ワイヤーへの油付与中の不織布に対する特性としては、先ず、ワイヤーが不織布を走行中に「よれ」の発生が起こる場合があるが、これは不織布の初期伸張弾性率に関係すること、ワイヤーが走行時の不織布のワイヤーを把持する度合いは圧縮時応力が関係すること、そして、ワイヤー表面の余剰油の吸収の度合いは不織布の油含浸性(油吸い上げ高さ)が関係することを検討の結果、知見した。 That is, as for the characteristics of the nonwoven fabric during application of oil to the wire, first, the occurrence of “twisting” may occur while the wire travels through the nonwoven fabric, which is related to the initial elastic modulus of elasticity of the nonwoven fabric. The degree of gripping of the nonwoven fabric wire during travel is related to the stress during compression, and the degree of absorption of excess oil on the wire surface is related to the oil impregnation property (oil uptake height) of the nonwoven fabric. As a result, I found out.
そこで、本発明は上記検討の結果に基づいて夫々の特性を探求し、初期伸張弾性率が4000〜7500N/50mm/100%で、0.5mm圧縮時応力が2.0〜0N/cm2/0.5mm ,揚油高さが1.0cm以上である特性を有することが本発明の目的達成に適性であることを見出した。 Therefore, the present invention explores the respective characteristics based on the results of the above investigation, and the initial tensile elastic modulus is 4000 to 7500 N / 50 mm / 100%, and the stress at the time of 0.5 mm compression is 2.0 to 0 N / cm 2 / It has been found that having the properties of 0.5 mm and the height of oil pumping of 1.0 cm or more is suitable for achieving the object of the present invention.
なお、ここで本発明不織布の目付質量,厚さも当該不織布をワイピング用不織布として使用する上で特定されることが通常であり、前述の如く目付質量としては80〜300g/m2の範囲が好ましく、厚さは1.5〜3.0mmの範囲が好適である。目付質量は80g/m2未満であるとワイヤーを挟み込んだ場合、ワイヤーを把持する不織布の量が少ないために圧縮特性が発現できず、またワイヤー付与の余分な油の吸収性が劣り塗布斑を起こすので好ましくない。 Here, the weight per unit area and thickness of the nonwoven fabric of the present invention are usually specified when the nonwoven fabric is used as a nonwoven fabric for wiping. As described above, the basis weight is preferably in the range of 80 to 300 g / m 2. The thickness is preferably in the range of 1.5 to 3.0 mm. When the weight is less than 80 g / m 2 , when the wire is sandwiched, the amount of nonwoven fabric that grips the wire is small, so compression characteristics cannot be expressed, and the absorption of excess oil applied to the wire is inferior. It is not preferable because it happens.
一方、目付質量は300g/m2を超えるとワイヤーを挟んだ不織布の特性が十分に発揮でき、均一な油の付与ができ、余分な油の吸収も十分であるが総合的に過剰品質となる。また、不織布の厚さが1.5mm未満であるとワイヤーを挟み込んだ場合、ワイヤーを把持する不織布の圧縮特性が発揮できず、ワイヤー表面の油を均一にすることが難しくなるので好ましくなく、一方、不織布の厚さが3.0mmを超えるとワイヤーを挟んだ不織布の特性は十分に発揮できるがコスト面から好ましくない。 On the other hand, when the mass per unit area exceeds 300 g / m 2 , the characteristics of the nonwoven fabric sandwiching the wire can be sufficiently exerted, uniform oil can be imparted, and excess oil can be absorbed sufficiently, but the overall quality becomes excessive. . In addition, when the wire is sandwiched when the thickness of the nonwoven fabric is less than 1.5 mm, the compression characteristics of the nonwoven fabric that holds the wire cannot be exhibited, and it is difficult to make the oil on the wire surface uniform. When the thickness of the nonwoven fabric exceeds 3.0 mm, the properties of the nonwoven fabric sandwiching the wire can be sufficiently exhibited, but this is not preferable from the viewpoint of cost.
次に上記不織布の特性については、先ず不織布の初期伸張弾性率は4000〜7500N/50mm/100%の範囲が良い。不織布の初期伸張弾性率が4000N/50mm/100%未満であると不織布で挟まれたワイヤーが走行中に不織布を引きずり易くなり、不織布自身がよれた状態になり易くなるので適切でなく、また、不織布の初期伸張弾性率が7500N/50mm/100%を超えると不織布で挟まれたワイヤーが走行中に不織布を引きずることはないが、表面が硬いためにワイヤー表面が斑になり易くなるので同様に適当でない。 Next, as for the characteristics of the nonwoven fabric, the initial tensile elastic modulus of the nonwoven fabric is preferably in the range of 4000 to 7500 N / 50 mm / 100%. If the initial tensile elastic modulus of the nonwoven fabric is less than 4000 N / 50 mm / 100%, the wire sandwiched between the nonwoven fabrics is likely to drag the nonwoven fabric during travel, and the nonwoven fabric itself is likely to be in a state of being twisted. If the initial elastic modulus of the nonwoven fabric exceeds 7500 N / 50 mm / 100%, the wire sandwiched between the nonwoven fabrics will not drag the nonwoven fabric during travel, but the surface of the wire is likely to become uneven because the surface is hard. Not appropriate.
また、不織布の0.5mm時圧縮応力は2.0〜10.0N/cm2/0.5mmの範囲が良く、不織布の0.5mm時圧縮応力が2.0N/cm2/0.5mm未満では不織布に挟まれたワイヤーが走行中に把持力が弱いためにワイヤー表面に油を均一に付与することが出来なくなるので好ましくなく、不織布の0.5mm時圧縮応力が10.0N/cm2/0.5mmを超えると不織布で挟まれたワイヤーが走行中に把持力が強すぎてワイヤー表面の油を均一に付与することが出来なくなるので好ましくない、更に不織布の油含浸性(油吸い上げ高さ)、即ち、揚油高さが1.0cm以上であることが重要である。不織布の揚油高さ(油吸い上げ高さ)が1.0cm未満であるとワイヤーに塗布した余分な油を速やかに吸収することが出来にくくワイヤーの表面に塗布斑を起こさせることがあるので好ましくない。 Further, 0.5 mm when the compression stress of the nonwoven fabric may have a range of 2.0~10.0N / cm 2 /0.5mm, 0.5mm when compressive stress of the nonwoven fabric is 2.0 N / cm less than 2 0.5 mM In this case, since the wire sandwiched between the nonwoven fabrics has a weak gripping force during traveling, it is not preferable since oil cannot be uniformly applied to the wire surface, and the compressive stress at 0.5 mm of the nonwoven fabric is 10.0 N / cm2 / 0. If the wire length exceeds 5 mm, the gripping force of the wire sandwiched between the nonwoven fabrics is too strong during travel, making it impossible to uniformly apply oil on the wire surface. That is, it is important that the pumping height is 1.0 cm or more. It is not preferable that the lifting height (oil suction height) of the nonwoven fabric is less than 1.0 cm because it is difficult to quickly absorb excess oil applied to the wire, and it may cause application spots on the surface of the wire. .
以上のように本発明不織布はワイピング用として上記各特性を具備することにより前記不織布構成と相俟ってワイヤー用ワイピング不織布としてワイヤーに油を付与する処理中においてワイヤーによってめくれ(不織布の皺)や不織布自身の剥離を生ずることもなく、効果的に油の均一付与,余剰オイルの拭き取りを行なうことができる。以下、更に本発明の具体的な実施例を比較例と対照して説明する。 As described above, the nonwoven fabric of the present invention has the above-mentioned properties for wiping, and in combination with the nonwoven fabric configuration, the wire is turned up by the wire during the process of applying oil to the wire as a wiping nonwoven fabric for wires (nonwoven fabric wrinkles) It is possible to effectively impart uniform oil and wipe off excess oil without causing the nonwoven fabric itself to peel off. Hereinafter, specific examples of the present invention will be described in contrast to comparative examples.
