Description
本発明は掃除をする際に使用する清掃布である。 The present invention is a cleaning cloth used for cleaning.
拭き掃除をする際に使用する拭き布として、従来より各種の織物、編物又は不織布等が用いられている。例えば、特許文献１にはパイル糸の単繊維繊度が０．１〜０．６デシテックスであるパイル織編物よりなるモップ用清掃布が記載されている。 Various woven fabrics, knitted fabrics, nonwoven fabrics, and the like have been used as wiping cloths used for wiping. For example, Patent Document 1 discloses a mop cleaning cloth made of a pile woven or knitted fabric having a single fiber fineness of a pile yarn of 0.1 to 0.6 decitex.
特許文献１記載の清掃布は汚れの拭き取り性を有するものであるが、パイル糸の単繊維繊度が細いため、清掃時の摩擦抵抗が高くなり、特にモップ等の清掃布として使用する際、拭き取り作業時に作業負荷がかかってしまうということがあった。
During cleaning cloth described in Patent Document 1 is Ru Oh those having wiping of dirt, for a single fiber fineness of the pile yarn is thin, the frictional resistance increases at the time of cleaning, in particular used as a cleaning cloth such as a mop, In some cases, a work load was applied during the wiping operation.
本発明の課題は、床等の清掃対象物との摩擦抵抗が低く、作業性が良好で、かつ優れた拭き取り性を発揮しうる清掃布を提供することにある。 An object of the present invention is to provide a cleaning cloth which has low frictional resistance with an object to be cleaned such as a floor, has good workability, and can exhibit excellent wiping properties.
本発明は、清掃布における摩擦抵抗の低減と拭き取り性の向上との両立をめざし、鋭意検討を行った結果、上記課題を解決したものである。 The present invention has solved the above-mentioned problems as a result of intensive studies with the aim of achieving both a reduction in frictional resistance and an improvement in wiping performance of a cleaning cloth.
すなわち、本発明は、布帛本体の少なくとも表面に多数の立毛繊維が設けられてなり、該立毛繊維が単繊維繊度１〜６デシテックスの熱可塑性合成繊維から構成されてなる立毛部を有する立毛布帛を準備し、該立毛布帛の立毛部表面に、加熱された気体を吹付けて、立毛した繊維を根本から横倒れさせ、立毛した繊維が根本から横倒れしている横倒れ領域と、繊維が起立して立毛してなる起立領域とを布帛表面に形成させることを特徴とする請求項１記載の清掃布の製造方法を要旨とするものである。
That is, the present invention comprises a large number of napped fibers on at least the surface of the fabric body, a raised fabric having a napped portion upstanding bristles fibers are formed of a thermoplastic synthetic fiber of a single fiber fineness 1-6 dtex Preparing and raising the raised fiber by blowing heated gas onto the raised surface of the raised fabric, causing the raised fiber to fall down from the root, and the upright region where the raised fiber falls down from the root, and the fiber standing up. A method for producing a cleaning cloth according to claim 1, wherein a raised area formed by raising the hair is formed on the surface of the cloth.
本発明における立毛布帛は、地組織となる布帛本体の少なくとも片面に多数の立毛繊維が設けられてなる立毛部を有する。この立毛繊維は清掃面（拭き取り面）となるものである。立毛繊維は単繊維繊度が１〜６デシテックスの熱可塑性合成繊維から構成されている。熱可塑性合成繊維を用いている理由は、後述する立毛した繊維を根本から横倒れさせるための過熱気体による作用を効果的に与えることができ、その横倒れの形態を維持しやすいからである。 The napped fabric in the present invention has a napped portion in which a large number of napped fibers are provided on at least one surface of a cloth main body that forms a ground structure. The nap fibers serve as a cleaning surface (wiping surface). The nap fibers are composed of thermoplastic synthetic fibers having a single fiber fineness of 1 to 6 dtex. The reason why the thermoplastic synthetic fiber is used is that an action by a superheated gas for causing the raised fiber described below to fall from the root can be effectively given, and the form of the fall can be easily maintained.
立毛繊維を構成する熱可塑性合成繊維としては、一般的にポリエステル繊維を用いることが好ましい。このとき、紡績糸や連続繊維であるフィラメント糸を用いることができるが、毛羽の発生を効果的に防止できることから、フィラメント糸を用いることが好ましい。フィラメント糸の場合、モノフィラメント糸ではなくマルチフィラメント糸を使用することが好ましい。モノフィラメント糸では単繊維繊度が６デシテックス以下のものは製造しにくいからである。 It is generally preferable to use polyester fibers as the thermoplastic synthetic fibers constituting the nap fibers. At this time, a spun yarn or a filament yarn that is a continuous fiber can be used, but it is preferable to use a filament yarn because generation of fluff can be effectively prevented. In the case of a filament yarn, it is preferable to use a multifilament yarn instead of a monofilament yarn. This is because it is difficult to produce a monofilament yarn having a single fiber fineness of 6 decitex or less.
単繊維繊度を１デシテックス以上とすることにより、立毛繊維の腰が強くなり、拭き取り性が向上する。また、単繊維繊度を６デシテックス以下とすることにより、単繊維が太くなりすぎず、塵埃等の拭き取り性が良好となる。単繊維の横断面形状は任意であってよいが円形よりも三角形等の異形である方が塵埃等の拭き取り性に優れているので好ましい。 By setting the single fiber fineness to 1 dtex or more, the stiffness of the nap fibers is strengthened, and the wiping property is improved. Further, by setting the single fiber fineness to 6 decitex or less, the single fiber does not become too thick, and the wiping property of dust and the like becomes good. The cross-sectional shape of the single fiber may be arbitrary, but it is preferable that the single fiber has a deformed shape such as a triangle shape rather than a circular shape because the shape is excellent in wiping dust and the like.
立毛の長さは、０．８〜５ｍｍが好ましく、より好ましくは０．８〜３ｍｍである。立毛の長さを０．８ｍｍ以上とすることにより、後述する起立領域と横倒れ領域との高低差（凹凸差）を明確に設けることができ、髪の毛や塵埃等の拭き取り性が向上する。立毛の長さが５ｍｍ以下にすることにより、拭き取り時の摩擦抵抗を小さくすることができ、作業性が向上しやすい。特に、立毛の長さを３ｍｍ以下にすると、拭き取り作業時においても、摩擦抵抗がより抑えられるので好ましい。 The nap length is preferably 0.8 to 5 mm, more preferably 0.8 to 3 mm. By setting the length of the naps to be 0.8 mm or more, a height difference (a difference in unevenness) between the erected region and the side-down region, which will be described later, can be clearly provided, and the wiping ability of hair, dust, and the like is improved. By setting the length of the nap to 5 mm or less, the frictional resistance during wiping can be reduced, and workability is easily improved. In particular, it is preferable to set the length of the nap to 3 mm or less, since the frictional resistance can be further suppressed even during the wiping operation.
立毛繊維の立毛密度は５０００本／ｃｍ２以上が好ましく、より好ましくは５０００〜２００００本／ｃｍ２である。立毛密度が５０００本／ｃｍ２以上とすることにより、塵埃等の拭き取り性がより向上する。特に、立毛密度を５０００〜２００００本／ｃｍ２にすると、拭き取り性に優れると共に、拭き取り作業時においての摩擦抵抗がより抑えられるので好ましい。 The nap density of the nap fibers is preferably 5000 fibers / cm 2 or more, and more preferably 5000 to 20,000 fibers / cm 2 . By setting the nap density to 5000 or more / cm 2 , the wiping property of dust and the like is further improved. In particular, setting the nap density to 5,000 to 20,000 needles / cm 2 is preferable because the wiping property is excellent and the frictional resistance during the wiping operation is further suppressed.
立毛布帛としては、編物、織物、タフト等の立毛布帛が挙げられ、織編物としては、ラッセル編やトリコット編等の経編み、シンカーパイル等の緯編み、モケット等の２重織物をセンターカットすることにより地組織の表面に立毛部を形成したもの等が挙げられる。本発明では、編物を採用し、なかでも経編物を好ましく採用する。編物は柔軟性を有するため取扱い性が良く、また、経編は、緯編のごとく幅方向に伸びる傾向がなく寸法安定性に優れているからである。編物を採用する場合、編地本体の編成は、一般的に、従来公知のマルチフィラメント糸を用いて行われる。編地本体の編成に用いるマルチフィラメント糸は、立毛部を形成している糸と同種のものであっても、異種であってもよい。一般的に、単繊維繊度は同程度であるが、糸条（例えば、マルチフィラメント糸）としたときの太さは細いものがよい。これは、編地本体の組織を緻密にするためである。また、単繊維の横断面も、異形のものよりも円形のものがよい。編地本体は、塵埃を拭き取る清掃面にはならないからである。 Examples of the upholstery fabric include upholstery fabrics such as knitted fabrics, woven fabrics, and tufts. As the woven knitted fabrics, warp knitting such as Russell knitting and tricot knitting, weft knitting such as sinker pile, and double woven fabrics such as moquettes are center-cut. Thus, there may be mentioned, for example, those having a raised portion formed on the surface of the ground tissue. In the present invention, a knitted fabric is used, and in particular, a warp knitted fabric is preferably used. This is because the knitted fabric has flexibility and is easy to handle, and the warp knit does not tend to stretch in the width direction like the weft knit and has excellent dimensional stability. When a knitted fabric is employed, knitting of the knitted fabric body is generally performed using a conventionally known multifilament yarn. The multifilament yarn used for knitting the knitted fabric main body may be of the same type as the yarn forming the nap portion or may be of a different type. In general, the fineness of the single fiber is almost the same, but a thin yarn (for example, a multifilament yarn) is preferably thin. This is for making the structure of the knitted fabric main body dense. Also, the cross section of the single fiber is preferably circular rather than irregular. This is because the knitted fabric main body does not become a cleaning surface for wiping dust.
例えば、立毛編物の編成は、立毛部を構成する単繊維繊度が１〜６デシテックスの熱可塑性合成繊維よりなるマルチフィラメント糸と、編地本体を構成するマルチフィラメント糸とを編機に供給することによって行われる。前者のマルチフィラメント糸は、パイルを形成するように編成され、このパイルが立毛部となる。パイルは、編成時に形成されたループパイルであってもよいし、このループパイルの先端を切断したカットパイルでもよい。 For example, knitting of a nap-knitted fabric involves supplying a knitting machine with a multi-filament yarn comprising a thermoplastic synthetic fiber having a single-fiber fineness of 1 to 6 dtex constituting a nap portion and a multi-filament yarn constituting a knitted fabric body. Done by The former multifilament yarn is knitted so as to form a pile, and this pile becomes a nap. The pile may be a loop pile formed at the time of knitting, or may be a cut pile obtained by cutting the tip of the loop pile.
本発明における立毛布帛は、布帛表面の立毛部を構成する立毛繊維の状態が、繊維が地組織に対して起立して立毛してなる「起立領域」と、立毛した繊維が地組織部分との略接点から横倒れしている、すなわち立毛繊維の根本の部分から横倒れして繊維が寝ている「横倒れ領域」とから構成される。このような「横倒れ領域」は、加熱した気体を吹付けることによる加圧と加熱による作用によって、立毛繊維をその根本から横倒れさせて形成させる。より具体的には、立毛布帛の立毛部表面に、ノズルから噴出される加熱された気体を吹付け、吹きつけられた箇所に存在する立毛繊維を、風圧の作用により立毛繊維の根本から左右に吹き分けられて倒し、また、熱の作用により熱可塑性樹脂からなる立毛繊維が吹き分けられて根本から倒れた状態で、軟化させ横倒れ状態を固定させる。なお、吹きつけられていない領域は、立毛繊維が、地組織に対して起立した状態をそのまま保持した「起立領域」となる。ノズルから噴出する加熱気体は、熱風や過熱蒸気が挙げられ、過熱蒸気を好ましく用いる。加熱された気体を吹付ける際、立毛繊維を構成する熱可塑性重合体が溶融せず、かつ軟化する温度を選択する。熱可塑性重合体が溶融し流動し始めると、繊維同士が融着して硬化してしまい繊維形態が維持されず、塵埃の拭き取り性に劣るものとなり、一方、軟化しないような温度では、吹付けにより横倒れが生じても、その横倒れ状態が固定されず、容易に起立してしまい、本発明が目的とするものが得られない。このような条件としては、例えば、立毛繊維がポリエチレンテレフタレートにより構成される場合、１５０〜１６０℃の過熱蒸気を０．３〜１ｋｇ／ｃｍ２程度の圧力で噴射すればよい。
In the raised fabric according to the present invention, the state of the raised fibers constituting the raised portions on the surface of the fabric is such that the fibers are raised with respect to the ground tissue and are raised. It is composed of a “side-down region” in which the fiber lies down from the substantially contact point, that is, the fiber lies down from the root of the nap fiber. Such "lateral collapse region", the action of heat and pressure caused by blowing pressurized hot gas, is formed let fall sideways napped fibers from their root. More specifically, a heated gas ejected from a nozzle is sprayed on the nap portion surface of the nap fabric, and the nap fibers existing in the sprayed portion are moved right and left from the root of the nap fibers by the action of wind pressure. The nap fibers made of a thermoplastic resin are blown apart by the action of heat and softened by the action of heat, so that the nap fibers are softened by the action of heat and fixed in a side-down state. In addition, the area | region which is not sprayed becomes the "upright area | region" which maintained the state in which the nap fiber was standing with respect to the ground structure as it is. Examples of the heated gas ejected from the nozzle include hot air and superheated steam. Superheated steam is preferably used. When the heated gas is blown, the temperature at which the thermoplastic polymer constituting the nap fibers does not melt and softens is selected. When the thermoplastic polymer starts to melt and flow, the fibers are fused and hardened, and the fiber form is not maintained, resulting in poor dust wiping properties. Therefore, even if a sideways fall occurs, the state of the sideward fall is not fixed, and the body easily stands up, so that the object of the present invention cannot be obtained. As such a condition, for example, when the napped fibers are made of polyethylene terephthalate, superheated steam at 150 to 160 ° C. may be injected at a pressure of about 0.3 to 1 kg / cm 2 .
本発明により得られる清掃布は、上記したように立毛繊維が地組織に対して起立してなる「起立領域」と、立毛繊維の根本の部分から横倒れして繊維が寝ている「横倒れ領域」とから構成される。横倒れ領域は、布帛表面において任意の形状に形成することができる。すなわち、加熱気体を噴射した箇所が横倒れ領域となるため、噴射の際に、直線状や波線状等の線状で、一定の模様やランダムな模様を形成するようにノズルを移動させて噴射すると、その噴出箇所が横倒れ領域となり、布帛に様々な模様を形成させることにもなる。横倒れ領域における繊維は、噴射方向に応じてあらゆる方向を向いて繊維が倒れていることから、拭き取りの際に、あらゆる方向に応じて塵埃を捕集することができる。布帛における「起立領域」と「横倒れ領域」との比率は、「起立領域」：「横倒れ領域」=３０〜７０：７０〜３０程度がよい。
As described above, the cleaning cloth obtained by the present invention includes a “raised area” in which the nap fibers are erected with respect to the ground tissue, and a “side-down area” in which the fibers lie down from the root of the nap fibers. Area ". The lateral falling region can be formed in an arbitrary shape on the fabric surface. In other words, since the location where the heated gas is injected becomes a side-down region, the nozzle is moved so as to form a fixed pattern or a random pattern in a linear or wavy line at the time of injection. Then, the spouted portion becomes a side-down area, and various patterns are formed on the cloth. Since the fibers in the side-down area are oriented in all directions according to the jetting direction, the fibers can be collected in all directions at the time of wiping. The ratio between the "standing region" and the "lateral falling region" in the fabric is preferably "standing region": "lateral falling region" = about 30 to 70:70 to 30.
本発明により得られる清掃布は、「起立領域」と「横倒れ領域」を有しており、起立領域は、立毛による厚みを有した凸領域となり、横倒れ領域は、立毛繊維が繊維の根本から寝ることにより凹領域となる。このように凹凸を有し、また、横倒れ領域における繊維が、繊維軸方向に方向性を持ってあらゆる方向に横倒れしていることから、拭き取り作業時の摩擦抵抗を軽減し、拭き取り作業者の負荷を低減させることができる。なお、横倒れ領域における繊維は、繊維の根元に向けて、繊維の横方向から圧がかかることによって繊維の根本から倒れているものであるため、繊維軸方向には座屈が生じずに、繊維軸方向には直線性を保持しているため、このような作用効果を奏する。すなわち、例えば、エンボスロール等を用いて部分的に布帛に押し当てる方法を採用し、ロールの凸部で繊維軸方向に押圧することにより繊維が押しつぶされ繊維の長手方向の中間点等において座屈することにより直線性を失い変形して倒れてなるものとは、その形態が全く異なる。
The cleaning cloth obtained according to the present invention has an “erected area” and a “laterally falling area”, and the upright area is a convex area having a thickness by napping, and the napping fiber is the root of the fiber. The sleeping area is turned into a concave area. Since the fibers in the side-down region have the unevenness as described above, and the fibers in the side-down region are directional in the fiber axis direction in all directions, the frictional resistance during the wiping operation is reduced, and Can be reduced. In addition, the fibers in the side-down region are those that fall from the roots of the fibers by applying pressure from the lateral direction of the fibers toward the base of the fibers, so that buckling does not occur in the fiber axis direction, Since the linearity is maintained in the fiber axis direction, such an effect is obtained. That is, for example, a method of partially pressing against the fabric using an embossing roll or the like is adopted, and the fiber is crushed by being pressed in the fiber axis direction at the convex portion of the roll, and buckling occurs at an intermediate point in the longitudinal direction of the fiber. Therefore, the form is completely different from the one that loses linearity and deforms and falls down.
本発明により得られる清掃布の目付は、２００〜５００ｇ／ｍ２程度がよい。目付を２５０ｇ／ｍ２以上であることにより、単繊維量を確保したうえで拭き取り容量を保持できる。また、布帛表面の凹凸構造の形態安定性が良好である。一方、目付を５００ｇ／ｍ２以下にすることにより、軽量であり、拭き取り作業時の負荷がかかりにくい。
The basis weight of the cleaning cloth obtained by the present invention is preferably about 200 to 500 g / m 2 . When the basis weight is 250 g / m 2 or more, the wiping capacity can be maintained while ensuring the amount of single fibers. In addition, the morphological stability of the uneven structure on the fabric surface is good. On the other hand, by setting the basis weight to 500 g / m 2 or less, the weight is light and the load during the wiping operation is not easily applied.
本発明により得られる清掃布は、乾拭きでも水分や各種洗浄用液体等を含ませたウェット状態で使用してもよい。また、清掃布をモップの柄のヘッド部に装着して、モップとして使用してもよい。この清掃布の立毛部の裏面に面ファスナーの雄材又は雌材を貼合した清掃布は、この雄材又は雌材を使用して、ヘッド部に装着しやすくなるので、好ましいものである。すなわち、ヘッド部に面ファスナーの雌材又は雄材を貼合しておき、該清掃布に雄材又は雌材を貼合しておくと、両者を係合することによって、ヘッド部に清掃布を装着しやすくなる。本発明により得られる清掃布は、水を保持させた後、ヘッド部に清掃布を装着し、柄を人手で持って、清掃布を床に押し付けて、水拭きしてもよい。また、本発明の清掃布は、立毛面を両表面になるように２枚を縫合し、モップの柄のヘッド部に装着せずに、手指で把持し、乾拭き及び水拭き用の両面雑巾として、好適に使用しうるものである。
The cleaning cloth obtained according to the present invention may be wiped dry or used in a wet state containing moisture, various cleaning liquids and the like. Further, a cleaning cloth may be mounted on the head of the handle of the mop and used as a mop. The cleaning cloth in which the male or female material of the hook-and-loop fastener is bonded to the back surface of the raised portion of the cleaning cloth is preferable because the male or female material can be easily attached to the head. That is, when a female or male material of the hook-and-loop fastener is pasted to the head portion, and a male or female material is pasted to the cleaning cloth, the cleaning cloth is attached to the head portion by engaging both. Easier to do. Cleaning cloth more obtained in the present invention, after holding the water, equipped with a cleaning cloth to the head portion, with a handle manually, by pressing a cleaning cloth on the floor, it may be wiped water. Further, the cleaning cloth of the present invention is obtained by suturing two sheets so that the napped surfaces are on both surfaces, and holding them with fingers without attaching to the head part of the handle of the mop, as a double-sided wipe for dry wiping and wiping with water. Which can be suitably used.
本発明の製造方法により得られる清掃布によれば、繊維が立っている領域と繊維の根本から倒れている領域とを有することから、拭き取り性を維持しつつ、拭き取り作業時の摩擦抵抗を軽減するとともに、拭き取り性が向上し、作業性と拭き取り性の両立を図ることができる。
According to the cleaning cloth obtained by the production method of the present invention , since there is a region where the fiber stands and a region where the fiber has fallen from the root, the frictional resistance during the wiping operation is reduced while maintaining the wiping property. At the same time, the wiping performance is improved, and both workability and wiping performance can be achieved.
以下、本発明について、実施例に基づいて説明する。
