Abstract
Description
本発明は、清掃用ワイパーに関するものであり、より詳細には微細なごみの捕集性に優れ、家庭やビルなどのフローリング床やタイル床、大理石フロアーなどのフロアー上や屋内壁面、天井面などの清掃用に好適であり、かつ安価な清掃用ワイパーに関する。 The present invention relates to a wiper for cleaning, and more particularly, is excellent in collecting fine dust, and cleaning of floors such as homes and buildings, tile floors, marble floors, indoor walls, ceiling surfaces, etc. The present invention relates to a cleaning wiper that is suitable for use and inexpensive.
従来、清掃用シート材として不織布が用いられており、その手軽さゆえに様々なところで使用されている。例えば、極細繊維と親水性繊維と交絡させた清掃用ワイパー（特許文献１参照）や、熱収縮性繊維層と非熱収縮繊維層とを積層し、凹凸構造を付与した清掃用ワイパー（特許文献２参照）等が提案されている。 Conventionally, a nonwoven fabric has been used as a cleaning sheet material, and is used in various places because of its simplicity. For example, a cleaning wiper (see Patent Document 1) entangled with ultrafine fibers and hydrophilic fibers, or a cleaning wiper provided with an uneven structure by laminating a heat-shrinkable fiber layer and a non-heat-shrinkable fiber layer (Patent Document) 2) and the like have been proposed.
また、清掃用シート材は、家庭やビルなどのフローリング床やタイル床、大理石フロアーなどのフロアー用にも用いられている。フロアー用に用いる場合、主に土、砂などの微小な埃や繊維くずなどの綿埃、毛髪などの収集、捕集性能が要求される。これらの性能に関係の深い要件として、構成繊維の繊度や形状、シートの見かけ密度、表面形態、そして作業性としてシートの形態安定性や摩擦耐久性、使用時の床との拭き抵抗などが挙げられ、これらの条件を各種調整した様々な提案がなされている。例えば、網状シートに極細繊維からなるウエブを積層、絡合した清掃用シート（特許文献３参照）や、捲縮繊維と熱融着性繊維を含むウエブと非収縮性繊維からなるウエブを積層し、一方の面に凸部を形成させたダストクロス（特許文献４参照）が提案されている。 Further, the cleaning sheet material is also used for floors such as flooring, tile floor, marble floor in homes and buildings. When used for flooring, collection and collection performance is mainly required for fine dust such as soil and sand, cotton dust such as fiber waste, and hair. The requirements closely related to these performances include the fineness and shape of the constituent fibers, the apparent density of the sheet, the surface form, and the workability such as the form stability and friction durability of the sheet, and the resistance to wiping with the floor during use. Various proposals have been made with various adjustments to these conditions. For example, a cleaning sheet (see Patent Document 3) obtained by laminating and intertwining a web made of ultrafine fibers on a net-like sheet, or a web made of crimped fibers and heat-fusible fibers and a web made of non-shrinkable fibers. A dust cloth (see Patent Document 4) in which a convex portion is formed on one surface has been proposed.
しかしながら、種々提案されている前述の清掃用ワイパーには以下のような問題がある。すなわち、極細繊維を主体とする清掃用ワイパーは、その構成繊維が極細であるため極微小な埃類の拭き取りには比較的有効であるが、得られる不織布が比較的薄く、またその見かけ繊維密度も大きくなりやすいため、フロアの清掃等に用いた場合にはサイズの大きいゴミが拭き取りにくく、またその捕集量も少なかった。また、熱収縮繊維と非熱収縮繊維との積層構造や混綿構成などによりシートの表面に凹凸形状を発現させたり、シート中の見かけ繊維密度を調整したりしたものは、製造設備上や熱収縮繊維の利用上手間がかかったり、様々な大きさのゴミに対する拭取り性については十分な性能を得ることが困難であった。一方、拭き取り物を繊維に絡みつかせ拭き取る効果を狙ったものは、繊維の自由度を比較的大きくさせる必要があり、その結果シートの形態安定性が劣り、芯材としてネットなどの複合により補強する必要が生じたり、極微小なゴミのシートのす抜けを防止するためにシート重量を高めにしたり、吸着薬剤を付着させるなどの二次的処理が必要となり、製造に手間がかかりやや高価になる。さらに前述のようないくつかの手法を組み合わせて用いないと拭き取り性は偏ったものとなり使用しづらいものとなる。 However, the various cleaning wipers that have been proposed have the following problems. In other words, a cleaning wiper mainly composed of ultrafine fibers is relatively effective in wiping off extremely fine dusts because its constituent fibers are extremely fine, but the resulting nonwoven fabric is relatively thin and its apparent fiber density Therefore, when used for cleaning the floor, it is difficult to wipe off large trash and the amount collected is small. Also, if the surface of the sheet is made uneven by adjusting the laminated structure of the heat-shrinkable fibers and non-heat-shrinkable fibers or the mixed cotton composition, or the apparent fiber density in the sheet is adjusted, it can be used on the production equipment or on heat shrinkage. It has been difficult to obtain sufficient performance in terms of wiping properties for dust of various sizes, and it takes time to use fibers. On the other hand, those that aim at the effect of wiping the wipes with the fibers need to have a relatively large degree of freedom of the fibers, and as a result, the sheet has poor shape stability and is reinforced by a composite such as a net as the core material Secondary treatments such as increasing the weight of the sheet or attaching an adsorbent to prevent slipping out of extremely small dust sheets, which is time-consuming and somewhat expensive. Become. Furthermore, the wiping performance is biased and difficult to use unless a combination of several methods as described above is used.
一方、拭き取り性を向上させるために拭き取り面の表面積を広げ、さらに凹凸構造を付与する手法としてエンボスによる型付けが挙げられ、圧着部が点在するよう配置された形態がよく知られている。しかしながら、これらは拭き取り時の捕集性に影響する因子の一つであるシートの嵩性の向上には比較的効果があるが、嵩性を重視しすぎるとシート強度の低下や表面の摩擦による毛羽立ちが大きくなり過ぎ、嵩性とこれら両者の適度な調整は困難であった。また、流動パラフィンなどの吸着薬剤の使用は、確かに微小埃から比較的大きなサイズのごみの捕集まで非常に有効であるが、使用時にゴミが吸着するとともに吸着薬剤がゴミを拭き取られた床表面にも付着し残留することとなる。これらは使用後、床上の異常な滑りを引き起こしたり、吸着性能が高いがゆえに逆に埃他のゴミによる再汚染（付着）の原因となる。特に、土・砂埃の多いビル内のフロアーやロビーへの使用には非常に問題となる。 On the other hand, as a technique for expanding the surface area of the wiping surface in order to improve wiping properties and further imparting a concavo-convex structure, embossing is cited, and a configuration in which crimping portions are scattered is well known. However, these are relatively effective in improving the bulkiness of the sheet, which is one of the factors affecting the trapping property at the time of wiping. The fluff became too large, and it was difficult to appropriately adjust the bulkiness and both. In addition, the use of adsorbents such as liquid paraffin is very effective from the collection of fine dust to relatively large-sized garbage, but the adsorbents were wiped off as they adsorbed during use. It will also adhere and remain on the floor surface. These may cause abnormal slipping on the floor after use, or may cause recontamination (adhesion) due to dust or other dust because of its high adsorption performance. In particular, it is very problematic for use on floors and lobbies in buildings with a lot of dirt and dust.
本発明は、このような点に鑑みてなされたものであり、その目的は、特にフロアー清掃に好適に用いられ、かつ安価で様々な大きさのゴミの拭き取り性能、捕集性能に優れた清掃用ワイパーを提供することにある。 The present invention has been made in view of such a point, and its purpose is particularly suitable for floor cleaning, and is an inexpensive cleaning with excellent wiping performance and collection performance for various sizes of dust.

該繊維には抗菌性を付与する目的で薬剤を複合させたものや環境にやさしい製品を得るという観点から再生樹脂を用いたもの、あるいはこれらの複合品、またこれ以外の目的で機能化された繊維等を使用しても差し支えない。 These fibers are combined with drugs for the purpose of imparting antibacterial properties, those using recycled resins from the viewpoint of obtaining environmentally friendly products, or composites of these, or functionalized for other purposes There is no problem even if fibers are used.
本発明の清掃用ワイパーは、極細繊維を４０質量％以上含む不織布から構成されることが好ましいが、他の繊維と併用した不織布を用いてもよい。また、他の不織布等の基材と積層した不織布等を用いてもよい。 Although the cleaning wiper of the present invention is preferably composed of a nonwoven fabric containing 40% by mass or more of ultrafine fibers, a nonwoven fabric used in combination with other fibers may be used. Moreover, you may use the nonwoven fabric etc. which were laminated | stacked with base materials, such as another nonwoven fabric.

本発明に用いる極細繊維の繊維径は２〜１０μｍが好ましく、より好ましくは３〜８μｍである。
The ultrafine fibers used in the present invention include fibers obtained by directly spinning, fibers that can be divided into ultrafine fibers, and a type of fiber that can be obtained by extracting a part of a composite fiber, a spunbond method or a melt blown fiber. Examples thereof include ultrafine fibers obtained by a method or the like.
The fiber diameter of the ultrafine fiber used in the present invention is preferably 2 to 10 μm, more preferably 3 to 8 μm.
本発明においては、メルトブローン極細繊維と短繊維とが混合された不織布ウエブが好ましく用いられる。さらに好ましくは、５ｄｔｅｘ以上の太繊度繊維を１０質量％以上含有させることであり、また上記のメルトブローン極細繊維と短繊維との混合物の補強のために、強度のあるスパンボンド不織布等の他の材料と積層させて、耐洗濯性、耐水性を向上させることができる。
とりわけ本発明においては、熱可塑性樹脂を押出機で溶融押出し、メルトブローダイへ導き、メルトブローノズルから紡糸する際に、繊度３〜２０ｄｔｅｘの比較的太繊度の繊維を連続的に噴出し部付近へ吹き込み、これら繊維状物を捕集成形装置にて捕集する手法が、目的とするウエブを容易に得ることができるので好ましい。
In the present invention, a nonwoven web in which meltblown ultrafine fibers and short fibers are mixed is preferably used. More preferably, the material contains 10% by mass or more of thick fine fibers of 5 dtex or more, and other materials such as a strong spunbond nonwoven fabric are used to reinforce the mixture of the meltblown ultrafine fibers and the short fibers. To improve washing resistance and water resistance.
In particular, in the present invention, when a thermoplastic resin is melt-extruded by an extruder, led to a melt blow die, and spun from a melt blow nozzle, fibers having a relatively large fineness of 3 to 20 dtex are continuously blown into the vicinity of the ejection portion. A method of collecting these fibrous materials with a collecting and forming apparatus is preferable because a target web can be easily obtained.
次に、得られたウエブのシート化には、熱エンボスやピンソニック、超音波等を使用して、熱圧着するのが望ましい。かかる熱圧着処理により清掃用ワイパーに凹部が形成される。本発明においては、シート化時の超音波処理または熱エンボス処理による強度の発現と表面の耐毛羽落ち性をクリアするために熱可塑性繊維を含むことが望ましく、シート構成繊維中で熱可塑性繊維が５０質量％以上含まれる様に構成されることが好ましい。これらの繊維はすでに述べたように熱可塑性の単独樹脂よりなるものでも数種混合された芯鞘繊維などの複合繊維でもよい。 Next, it is desirable that the obtained web is made into a sheet by thermocompression bonding using hot embossing, pin sonic, ultrasonic waves, or the like. A concave portion is formed in the cleaning wiper by the thermocompression treatment. In the present invention, it is desirable to include a thermoplastic fiber in order to clear the expression of strength by ultrasonic treatment or heat embossing treatment at the time of forming a sheet and the surface fluff resistance, and the thermoplastic fiber in the sheet constituting fiber is It is preferable to be configured to be contained by 50% by mass or more. As described above, these fibers may be made of a single thermoplastic resin or may be a composite fiber such as a core-sheath fiber mixed with several kinds of fibers.
本発明の清掃用ワイパーにおいては、かかる熱圧着された部分の総面積が不織布表面積の３〜２０％を占めることが好ましい。熱圧着面積率が２０％を超えると不織布が硬くなり、拭き取り性等が悪くなる場合がある。一方、熱圧着面積率が３％未満であると、繊維を十分に固定することが難しくなり、表面毛羽が発生し、洗濯のような物理的な外部からの衝撃に耐えることができず、不織布形態が崩れる場合がある。より優れた拭き取り性や、表面毛羽抑制効果、洗濯耐久性が発揮できる点から熱圧着面積率は３〜２０％が好ましく、より好ましくは５〜１５％である。 In the cleaning wiper of the present invention, it is preferable that the total area of the thermocompression-bonded portion occupies 3 to 20% of the surface area of the nonwoven fabric. When the thermocompression bonding area ratio exceeds 20%, the nonwoven fabric becomes hard and the wiping property or the like may deteriorate. On the other hand, if the area ratio of thermocompression bonding is less than 3%, it becomes difficult to sufficiently fix the fibers, surface fluff is generated, and it cannot withstand physical external impact such as washing, and the nonwoven fabric. The form may collapse. 3-20% is preferable, and, more preferably, it is 5-15% from the point which can demonstrate the more excellent wiping off property, surface fluff suppression effect, and washing durability.
本発明の清掃用ワイパーは、凹凸形状を有し、かつ凸部の形状が、多数の不連続な直線状および／またはドット状の凹部の組合せによって六角形の連続模様を呈することを特徴とする。かかる凸部が、六角形の連続模様を呈することによって、あらゆる拭きとり方向に対してもゴミ捕集が容易となり、またワイパー使用時におけるワイパーと被清掃部との摩擦係数を低減させることができ、作業性が向上する。上記の六角形の形状は、できるだけ正六角形に近い形状が上記の作用効果達成のためにも好ましいが、それに限定されるものではない。なお、六角形を形成する一辺の長さはそれぞれ３〜３０ｍｍ程度が好ましく、より好ましくは５〜２０ｍｍである。なお、本発明におけるドット状の凹部は、円形、菱形、多角形など特に限定されない。 The cleaning wiper according to the present invention has an uneven shape, and the shape of the convex portion exhibits a hexagonal continuous pattern by a combination of a large number of discontinuous linear and / or dot-shaped concave portions. . Such convex portions exhibit a hexagonal continuous pattern, making it easy to collect dust in any wiping direction and reducing the friction coefficient between the wiper and the part to be cleaned when using the wiper. , Workability is improved. The hexagonal shape is preferably as close to a regular hexagon as possible in order to achieve the above effects, but is not limited thereto. In addition, about 3-30 mm is preferable for the length of each side which forms a hexagon, More preferably, it is 5-20 mm. In addition, the dot-shaped recessed part in this invention is not specifically limited, such as circular, a rhombus, and a polygon.
以下、図面を用いて本発明を詳細に説明する。図１は、本発明の清掃用ワイパーの一例を示す全体模式図である。本発明の清掃用ワイパーは上記した繊維により構成され、該清掃用ワイパーのほぼ全面に六角形の連続模様が形成されている。図２および図３は、本発明の清掃用ワイパーの一例を示す表面模式図であって、多数の不連続な直線状の凹部１により、凸部２が六角形の連続模様を呈している。また、図４は、本発明の清掃用ワイパーの一例を示す断面模式図であり、凹凸形状を有しているのがわかる。本発明にいう凹部は、例えば金属ロールの表面に凹凸柄が施されたエンボスロールとフラットな金属ロール間にウエブを通し、熱圧着処理することにより形成させることができる。また、凸部２の嵩高性を損なわないために、超音波加工を行うことによっても目的を達成することもできる。
Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is an overall schematic view showing an example of a cleaning wiper according to the present invention. The cleaning wiper of the present invention is composed of the above-described fibers, and a hexagonal continuous pattern is formed on almost the entire surface of the cleaning wiper. 2 and 3 are schematic surface views showing an example of the cleaning wiper according to the present invention. The
また、該凹部は、破線状に設置されたものの方が、凸部の嵩高性低下を防ぐ役割を果たし優れた拭取り性を発揮するのでより好ましい。なお、凹部を破線状に配置する際、各破線の長さは、０．５〜３ｍｍ程度が好ましく、また破線同士の間隔は０．５〜３ｍｍが好ましい。一方、該破線の幅は０．１〜１．５ｍｍが好ましい。 Further, it is more preferable that the concave portion is arranged in a broken line shape because it plays a role of preventing a decrease in the bulkiness of the convex portion and exhibits excellent wiping properties. In addition, when arrange | positioning a recessed part in the shape of a broken line, the length of each broken line is preferable about 0.5-3 mm, and the space | interval of broken lines is preferable 0.5-3 mm. On the other hand, the width of the broken line is preferably 0.1 to 1.5 mm.
本発明の清掃用ワイパーに形成される凸部は、繊維間に熱融着部分をほとんど有しない部位をいい、嵩高な拭取り部の役割を果たす。この凸部は、拭取り時における不織布シートのクッション性の発現や拭取り時の捕集部となり、清掃用ワイパーとしての重要な部位であり、これを形成するエンボスロール柄の形状は前述の六角形状に設定する。 The convex part formed in the cleaning wiper of the present invention refers to a part having almost no heat fusion part between the fibers, and serves as a bulky wiping part. This convex part becomes an expression part of the cushioning property of the nonwoven fabric sheet at the time of wiping and a collecting part at the time of wiping, and is an important part as a cleaning wiper. The shape of the embossing roll pattern forming this is the hexagon described above. Set to shape.
本発明の清掃用ワイパーを構成する不織布における凸部の高さは、０．５〜３ｍｍが好ましく、０．７〜２ｍｍがより好ましい。凸部の高さが０．５ｍｍ未満であると、ゴミの拭取り性が悪くなり、一方、凸部の高さが３ｍｍを超えると、不経済となり操作性が低下する場合がある。 0.5-3 mm is preferable and, as for the height of the convex part in the nonwoven fabric which comprises the wiper for cleaning of this invention, 0.7-2 mm is more preferable. When the height of the convex portion is less than 0.5 mm, the wiping property of dust is deteriorated. On the other hand, when the height of the convex portion exceeds 3 mm, it becomes uneconomical and the operability may be lowered.
本発明の清掃用ワイパーを構成する不織布は、目付４０〜１２０ｇ／ｍ２が好ましく、より好ましくは５０〜１００ｇ／ｍ２のものが用いられる。目付が４０ｇ／ｍ２未満では、拭取り性が悪くなり、不織布そのものの強度が低くなる場合がある。逆に、目付が１２０ｇ／ｍ２を超えるものでは、十分な強度を有するものの操作性も低下し、コスト的に不利となる場合がある。 The nonwoven fabric constituting the cleaning wiper of the present invention preferably has a basis weight of 40 to 120 g / m 2 , more preferably 50 to 100 g / m 2 . When the basis weight is less than 40 g / m 2 , the wiping property is deteriorated, and the strength of the nonwoven fabric itself may be lowered. On the other hand, when the basis weight exceeds 120 g / m 2 , the operability is lowered although the strength is sufficient, which may be disadvantageous in cost.
本発明の清掃用ワイパーは、柄付きの基台に取り付けてモップ等の清掃具として使用してもよいし、そのまま手で拭き取り作業を行ってもよい。 The cleaning wiper of the present invention may be attached to a base with a handle and used as a cleaning tool such as a mop, or may be directly wiped by hand.

また、実施例１〜４で得られた清掃用ワイパーを市販のフローリング用清掃器具に装着し、大学の廊下、ショッピングセンター共用通路（Ｐタイルおよびリノリューム製）や病院の廊下などでモニターテストを行ったところ、比較例１の清掃用ワイパーに較べ床との滑りも良好であり、かつゴミの拭き取り性もよく、操作性も極めてよいものであった。
As is clear from Table 1, the cleaning wipers obtained in Examples 1 to 4 have a better dust removal rate than Comparative Example 1, and the cleaning wiper protrusions include Kanto Loam and carbon black. And 15 kinds of test dust consisting of cotton linter were collected efficiently.
In addition, the cleaning wipers obtained in Examples 1 to 4 are mounted on a commercially available floor cleaning tool, and a monitor test is performed in a university corridor, a shopping center common passage (P tile and Linoleum), a hospital corridor, etc. As a result, compared with the cleaning wiper of Comparative Example 1, the sliding with the floor was also good, the dust wiping property was good, and the operability was very good.
上記の結果から、本発明の清掃用ワイパーは、いずれも優れた性能（静摩擦係数、ダスト除去率）を示していることが分かる。また、特に実施例４の清掃用ワイパーは、幾度かの洗濯した後でも良好に使用でき、濡れた場所においても耐久性良好に用いることができるという利点を有している。 From the above results, it can be seen that the cleaning wiper of the present invention exhibits excellent performance (coefficient of static friction, dust removal rate). In particular, the cleaning wiper of Example 4 has the advantage that it can be used well even after being washed several times, and can be used with good durability even in wet locations.
