Abstract
Description
本発明は、主として台所用に適した拭き布に関し、台所回りの油汚れなどを除去するのに適した拭き布に関するものである。 The present invention relates to a wiping cloth suitable mainly for kitchen use, and relates to a wiping cloth suitable for removing oil stains and the like around the kitchen.
従来より、台所回りの油汚れなどを除去するための拭き布として、紙製拭き布や布製拭き布が用いられている。しかしながら、台所回りの油汚れは、強固に付着していることが多く、単なる紙製又は布製拭き布では、除去しにくいということがあった。 Conventionally, paper wipes and cloth wipes have been used as wipes for removing oil stains and the like around the kitchen. However, oil stains around the kitchen are often firmly attached, and it has been difficult to remove with simple paper or cloth wipes.
このため、紙製又は布製拭き布に多数の孔を穿ち、孔の端縁で油汚れを掻き取ることが考えられる。また、紙製又は布製拭き布の表面を凹凸にして、凸部で油汚れを掻き取ることが考えられる。 For this reason, it is conceivable to make a large number of holes in a paper or cloth wiping cloth and to scrape off oil stains at the edges of the holes. It is also conceivable that the surface of the paper or cloth wipe is made uneven and the oil stain is scraped off by the convex portion.
そこで、本発明者などは、本件出願人が既に提案している拭き取りシート（特許文献１）を用いて、油汚れの除去を試みた。この拭き取りシートは、極細繊維と吸水性繊維とが均一に混合されてなる不織布製拭き布であり、その表面に凹凸模様が施されており、この凹凸模様は、拭き取り時においても消失しにくいものである。しかしながら、極細繊維を用いると、繊維径が細いため繊維に剛性がなく、油汚れを良好に掻き取ることが困難であった。また、吸水性繊維が全体に均一に混合されているため、水に浸漬したとき、吸水性繊維が膨潤し、凹凸模様の各凸部が柔らかくなり、油汚れを掻き取りにくくなるということがあった。 Therefore, the present inventors tried to remove oil stains using a wiping sheet (Patent Document 1) already proposed by the present applicant. This wipe sheet is a non-woven wipe made by mixing ultrafine fibers and water-absorbent fibers uniformly, and has a concavo-convex pattern on its surface, and this concavo-convex pattern is difficult to disappear even when wiping. It is. However, when ultrafine fibers are used, since the fiber diameter is small, the fibers are not rigid and it is difficult to scrape off oil stains well. In addition, since the water-absorbent fibers are uniformly mixed throughout, the water-absorbent fibers swell when immersed in water, and the convex portions of the concavo-convex pattern become soft, making it difficult to scrape oil stains. It was.
したがって、本発明者などは、特許文献１に記載されている拭き取りシートを、油汚れが良好に除去しうる拭き布とするためには、繊維径の細い極細繊維を用いずに、比較的繊維径の太い繊維を用いて、油汚れを掻き取りやすくすること、及び吸水性繊維乃至は親水性繊維を用いないで、水に含浸させても、凸部が柔らかくならないようにすることが、重要であると考えた。しかしながら、吸水性繊維乃至は親水性繊維を用いないと、拭き布自体に水を十分に含浸させることができず、油汚れなどに対して水を供給することができないため、油汚れが軟化せず、やはり油汚れが除去しにくいということが判明した。 Therefore, in order to make the wiping sheet described in Patent Document 1 a wiping cloth from which oil stains can be satisfactorily removed, the inventors of the present invention do not use ultrafine fibers having a small fiber diameter, and relatively fibers. It is important to make it easy to scrape oil stains using fibers with a large diameter, and to prevent the protrusions from becoming soft even when impregnated with water without using water-absorbing fibers or hydrophilic fibers. I thought. However, if water-absorbing fibers or hydrophilic fibers are not used, the wiping cloth itself cannot be sufficiently impregnated with water, and water cannot be supplied to oil stains. It was also found that oil stains are difficult to remove.
そこで、本発明者などは、吸水性繊維乃至は親水性繊維を用いながら、凸部が柔らかくなりにくく、しかも、拭き取り面の油汚れなどの汚れに対して水を供給しうる拭き布を得ることを課題として、研究を行った。この結果、拭き布を、疎水性繊維を主体とした合成繊維層と親水性繊維を主体とした親水性繊維層の二層構造とし、合成繊維層を特定の繊維組成とし、且つ各繊維相互間を交絡及び結合させれば、上記した課題を解決しうることを見出した。本発明は、このような知見に基づくものである。 Therefore, the present inventors obtain a wiping cloth that can easily supply water to dirt such as oil stains on the wiping surface while the water-absorbing fiber or hydrophilic fiber is used. The research was conducted with this as an issue. As a result, the wiping cloth has a two-layer structure of a synthetic fiber layer mainly composed of hydrophobic fibers and a hydrophilic fiber layer mainly composed of hydrophilic fibers, the synthetic fiber layer has a specific fiber composition, and each fiber It has been found that the above-mentioned problems can be solved by entanglement and coupling. The present invention is based on such knowledge.
すなわち、本発明は、合成繊維層と親水性繊維層とが積層一体化されてなる二層繊維構造物であって、少なくとも合成繊維層表面には凹凸模様が施されてなる拭き布であって、該合成繊維層は、熱接着性繊維と繊度５デシテックス以上の疎水性繊維とが均一に混合され、各繊維相互間が交絡されてなると共に各繊維相互間は該熱接着性繊維の軟化又は溶融によって結合されており、該親水性繊維層は親水性繊維相互間が交絡されてなるものであり、且つ、該合成繊維層と該親水性繊維層の層間において、該親水性繊維と該疎水性繊維及び該熱接着性繊維とが交絡されていると共に、該熱接着性繊維の軟化又は溶融によって各繊維相互間が結合されており、該拭き布を水に浸漬した場合であっても、凹凸模様が消失しないことを特徴とする、主として台所用に適した拭き布に関するものである。 That is, the present invention is a two-layer fiber structure in which a synthetic fiber layer and a hydrophilic fiber layer are laminated and integrated, and at least a surface of the synthetic fiber layer has a concavo-convex pattern, In the synthetic fiber layer, heat-adhesive fibers and hydrophobic fibers having a fineness of 5 dtex or more are uniformly mixed, and the fibers are entangled with each other. Bonded by melting, the hydrophilic fiber layer is entangled between hydrophilic fibers, and between the synthetic fiber layer and the hydrophilic fiber layer, the hydrophilic fiber and the hydrophobic fiber layer. The fibers are entangled with the heat-adhesive fibers and the fibers are bonded to each other by softening or melting the heat-adhesive fibers, and even when the wiping cloth is immersed in water, The main feature is that the uneven pattern does not disappear It relates to wiping cloth suitable for use in the kitchen with.
本発明に係る拭き布は、合成繊維層と親水性繊維層とが積層一体化されてなる二層繊維構造物よりなるものである。そして、少なくとも合成繊維層表面には、凹凸模様が施されてなるものである。すなわち、合成繊維層表面に凹部と凸部を持つものである。凹部と凸部の高低差は任意であるが、高低差があまり少ないと、凸部によって油汚れなどを掻き取りにくくなる傾向が生じる。また、合成繊維層表面全体が被拭き取り面と接触するため、合成繊維層表面が毛羽立ちやすくなり、繰り返し拭き取り作業性が悪くなる。一方、高低差があまりにも大きいと、手指で把持しにくくなり、使用しにくくなる傾向が生じる。一般的には、この高低差は１ｍｍ程度である。 The wiping cloth according to the present invention comprises a two-layer fiber structure in which a synthetic fiber layer and a hydrophilic fiber layer are laminated and integrated. Then, at least the surface of the synthetic fiber layer is provided with an uneven pattern. That is, it has a recessed part and a convex part on the synthetic fiber layer surface. The height difference between the concave portion and the convex portion is arbitrary, but if the height difference is too small, the convex portion tends to make it difficult to scrape oil stains and the like. In addition, since the entire surface of the synthetic fiber layer is in contact with the surface to be wiped, the surface of the synthetic fiber layer is easily fuzzed, and the repeated wiping workability is deteriorated. On the other hand, if the height difference is too large, it tends to be difficult to use with fingers and difficult to use. Generally, this height difference is about 1 mm.
凹凸模様は、合成繊維層表面にのみ設けられていてもよいし、合成繊維層表面と親水性繊維層表面の両面に設けられていてもよい。両面に設ける具体的態様としては、図１に示したような、断面波状の態様が好ましい。図１は、本発明の一例に係る拭き布の断面図を示したものであり、黒色で塗りつぶされている箇所１が、断面を表している。そして、断面間の曲線２は、断面の背後に見える凹部及び凸部を表している。すなわち、図１に示した凹凸模様は、合成繊維層表面の凸部が親水性繊維層表面の凹部に対応し、合成繊維層表面の凹部が親水性繊維層表面の凸部に対応した構成となっている。
The uneven pattern may be provided only on the surface of the synthetic fiber layer, or may be provided on both surfaces of the surface of the synthetic fiber layer and the surface of the hydrophilic fiber layer. As a specific mode provided on both sides, a cross-sectional wave mode as shown in FIG. 1 is preferable. FIG. 1 shows a cross-sectional view of a wiping cloth according to an example of the present invention, and a portion 1 painted in black represents a cross section. And the
本発明において、合成繊維層の繊維組成は、以下のようになっている。すなわち、疎水性繊維と熱接着性繊維とが均一に混合された組成となっている。疎水性繊維としては、水を吸収しにくいもので、ポリオレフィン系繊維やポリエステル系繊維などが用いられる。水を吸収しやすいものを用いると、疎水性繊維が膨潤して、その剛性が低下するからである。すなわち、合成繊維層は、凹凸模様が施されており、油汚れなどの拭き取り面となるものであるから、この層の剛性が低下すると、凸部の剛性も低下し、油汚れなどを掻き取りにくくなるからである。疎水性繊維は、その繊度が５デシテックス以上のものが採用される。５デシテックス未満の疎水性繊維を用いると、疎水性繊維の剛性が低くなり、油汚れなどを掻き取りにくくなるので、好ましくない。疎水性繊維の繊維長は任意でよく、一般的には、１０〜１００ｍｍ程度である。 In the present invention, the fiber composition of the synthetic fiber layer is as follows. That is, it has a composition in which hydrophobic fibers and heat-bondable fibers are uniformly mixed. Hydrophobic fibers are those that do not readily absorb water, and polyolefin fibers, polyester fibers, and the like are used. This is because if a material that easily absorbs water is used, the hydrophobic fiber swells and its rigidity decreases. That is, since the synthetic fiber layer has a concavo-convex pattern and serves as a wiping surface for oil stains, when the rigidity of this layer decreases, the rigidity of the convex portion also decreases and the oil stains are scraped off. This is because it becomes difficult. A hydrophobic fiber having a fineness of 5 dtex or more is employed. Use of hydrophobic fibers of less than 5 dtex is not preferable because the rigidity of the hydrophobic fibers becomes low and it becomes difficult to scrape oil stains. The fiber length of the hydrophobic fiber may be arbitrary, and is generally about 10 to 100 mm.
熱接着性繊維としては、その融点（結晶性が低く、明確な融点を有しないものは軟化点を融点とみなす。）が疎水性繊維の融点よりも低いものであれば、どのようなもので採用しうる。具体的には、低融点ポリエステル系繊維などが用いられる。特に、芯成分が高融点ポリエステルで、鞘成分が低融点ポリエステルよりなる芯鞘型複合繊維を用いるのが好ましい。芯鞘型複合繊維の場合、鞘成分のみが溶融又は軟化して、各繊維相互間を結合し、芯成分は当初の繊維状態が維持されるので、合成繊維層の風合いが低下しにくいのである。熱接着性繊維の繊度は任意でよいが、一般的には、１〜５デシテックス程度が好ましい。また、熱接着性繊維の繊維長も任意でよく、一般的には、１０〜１００ｍｍ程度である。 Any heat-adhesive fiber can be used as long as its melting point (low crystallinity and no clear melting point is considered to be the softening point) is lower than the melting point of the hydrophobic fiber. Can be adopted. Specifically, a low melting point polyester fiber or the like is used. In particular, it is preferable to use a core-sheath type composite fiber in which the core component is a high melting point polyester and the sheath component is a low melting point polyester. In the case of the core-sheath type composite fiber, only the sheath component is melted or softened to bond each fiber, and the core component maintains the original fiber state, so that the texture of the synthetic fiber layer is not easily lowered. . The fineness of the heat-adhesive fiber may be arbitrary, but generally about 1 to 5 dtex is preferable. Further, the fiber length of the heat-adhesive fiber may be arbitrary, and is generally about 10 to 100 mm.
本発明において、親水性繊維層の繊維組成は、親水性繊維を主体とするものである。親水性繊維としては、水をよく吸収するもので、一般的にはセルロース繊維が用いられる。セルロース繊維の中でも、特に、レーヨン繊維又はコットン繊維を用いるのが好ましい。親水性繊維の繊度は任意でよいが、一般的には、１〜５デシテックス程度が好ましい。また、親水性繊維の繊維長も任意でよく、一般的には、１０〜１００ｍｍ程度である。なお、親水性繊維層に若干量の他種繊維が混入されていても、水の吸収保持を阻害しない程度であれば、差し支えない。 In the present invention, the fiber composition of the hydrophilic fiber layer is mainly composed of hydrophilic fibers. As the hydrophilic fiber, it absorbs water well, and cellulose fiber is generally used. Among cellulose fibers, it is particularly preferable to use rayon fibers or cotton fibers. The fineness of the hydrophilic fiber may be arbitrary, but generally about 1 to 5 dtex is preferable. Further, the fiber length of the hydrophilic fiber may be arbitrary, and is generally about 10 to 100 mm. In addition, even if a slight amount of other types of fibers are mixed in the hydrophilic fiber layer, there is no problem as long as it does not hinder the absorption and retention of water.
合成繊維層と親水性繊維層との質量比は任意であるが、合成繊維層１００質量部に対して、親水性繊維層は２０〜５００質量部程度であるのが好ましく、特に３０〜３００質量部程度であるのがより好ましい。また、本発明に係る拭き布中には、疎水性繊維は少なくとも２５質量％以上含有されているのが好ましい。疎水性繊維の量が２５質量％未満であると、疎水性繊維の剛性を利用して、油汚れなどを掻き取りにくくなる傾向が生じる。一方、親水性繊維の量も２５質量％以上であるのが好ましく、特に３０質量％以上がより好ましく、とりわけ４０〜６０質量％であるのが好ましい。親水性繊維の量が２５質量％未満になると、拭き布に含浸される水の量が少なくなり、拭き取り面の油汚れなどに水を十分に供給しにくくなる傾向が生じる。なお、熱接着性繊維の量も任意であるが、一般的には、５〜２０質量％程度である。熱接着性繊維は、それ自身の軟化又は溶融によって、繊維相互間を結合するものであるため、その量が多すぎると拭き布が硬くなりすぎて使用しにくくなる傾向が生じる。一方、その量が少なすぎると、各繊維相互間の結合が不十分となり、合成繊維層表面の凸部が柔らかくなって、油汚れなどを掻き取りにくくなる傾向が生じる。 Although the mass ratio of the synthetic fiber layer and the hydrophilic fiber layer is arbitrary, the hydrophilic fiber layer is preferably about 20 to 500 parts by mass, particularly 30 to 300 parts by mass with respect to 100 parts by mass of the synthetic fiber layer. More preferably, it is about a part. Moreover, it is preferable that at least 25 mass% or more of hydrophobic fibers are contained in the wiping cloth according to the present invention. If the amount of the hydrophobic fiber is less than 25% by mass, the rigidity of the hydrophobic fiber tends to be used to make it difficult to scrape oil stains. On the other hand, the amount of the hydrophilic fiber is also preferably 25% by mass or more, more preferably 30% by mass or more, and particularly preferably 40 to 60% by mass. When the amount of the hydrophilic fiber is less than 25% by mass, the amount of water impregnated in the wiping cloth is reduced, and there is a tendency that it is difficult to sufficiently supply water to oil stains on the wiping surface. In addition, although the quantity of a heat bondable fiber is also arbitrary, generally it is about 5-20 mass%. Since the heat-bonding fibers are bonded to each other by their own softening or melting, if the amount is too large, the wiping cloth tends to be too hard and difficult to use. On the other hand, if the amount is too small, the bonding between the fibers becomes insufficient, the convex portions on the surface of the synthetic fiber layer become soft, and there is a tendency that oil stains and the like are hardly scraped off.
合成繊維層及び親水性繊維層の各繊維相互間は、水流交絡処理やニードルパンチ処理などによって交絡されている。すなわち、合成繊維層中では疎水性繊維及び熱接着性繊維の各繊維相互間が交絡されており、親水性繊維層中では親水性繊維相互間が交絡されている。そして、合成繊維層と親水性繊維層との層間では、疎水性繊維、熱接着性繊維及び親水性繊維の各繊維相互間が交絡されている。また、各繊維相互間は、交絡していると共に、熱接着性繊維の軟化又は溶融によって、結合している。この結合は、繊維相互間の交絡と相俟って、合成繊維層表面に設けられた凹凸模様を保持するためのものである。 The fibers of the synthetic fiber layer and the hydrophilic fiber layer are entangled by a hydroentanglement process, a needle punch process, or the like. That is, in the synthetic fiber layer, the fibers of the hydrophobic fiber and the heat-bonding fiber are entangled, and in the hydrophilic fiber layer, the hydrophilic fibers are entangled. And between the synthetic fiber layer and the hydrophilic fiber layer, the fibers of the hydrophobic fiber, the heat-bonding fiber and the hydrophilic fiber are entangled with each other. In addition, the fibers are entangled and bonded by softening or melting of the heat-bonding fibers. This bond is for holding the concavo-convex pattern provided on the surface of the synthetic fiber layer in combination with the entanglement between the fibers.
本発明に係る拭き布は、代表的には、以下の方法によって製造することができる。すなわち、熱接着性繊維と繊度５デシテックス以上の疎水性繊維とが均一に混合されてなる合成繊維層ウェブと、親水性繊維よりなる親水性繊維層ウェブとを積層した二層ウェブに、水流交絡処理を施して、該熱接着性繊維と該疎水性繊維相互間が交絡されてなる合成繊維層と、該親水性繊維相互間が交絡されてなる親水性繊維層とを形成すると共に、各層間において、該親水性繊維と該疎水性繊維及び該熱接着性繊維とが交絡されてなる二層積層物を形成した後、該二層積層物を一対の加熱された凹凸ロール間を通して、該熱接着性繊維を軟化又は溶融させて、各繊維相互間を結合すると共に、該合成繊維層表面及び該親水性繊維層表面に凹凸模様を施すという方法によって、製造することができる。 The wipe according to the present invention can typically be produced by the following method. That is, hydroentanglement is carried out on a two-layer web obtained by laminating a synthetic fiber layer web in which heat-adhesive fibers and hydrophobic fibers having a fineness of 5 dtex or more are uniformly mixed and a hydrophilic fiber layer web made of hydrophilic fibers. A treatment is performed to form a synthetic fiber layer in which the thermal adhesive fibers and the hydrophobic fibers are entangled with each other, and a hydrophilic fiber layer in which the hydrophilic fibers are entangled with each other. And forming the two-layer laminate formed by entanglement of the hydrophilic fiber, the hydrophobic fiber and the heat-adhesive fiber, and then passing the two-layer laminate through a pair of heated concavo-convex rolls. It can be produced by a method of softening or melting the adhesive fibers to bond the fibers to each other and forming a concavo-convex pattern on the surface of the synthetic fiber layer and the surface of the hydrophilic fiber layer.
合成繊維層ウェブ及び親水性繊維層ウェブの各繊維ウェブを形成する際に用いる、疎水性繊維、熱接着性繊維及び親水性繊維は、前に説明したとおりである。合成繊維層ウェブを形成するには、疎水性繊維と熱接着性繊維を均一に混合（混綿）した後、カード機などの開繊機で開繊し、これをシート状にすればよい。また、親水性繊維層ウェブを形成するには、親水性繊維をカード機などの開繊機で開繊し、これをシート状にすればよい。そして、合成繊維層ウェブと親水性繊維層ウェブとを積層して二層ウェブを得た後、この二層ウェブに水流交絡処理を施して、各繊維相互間を交絡させて繊維フリースを得る。水流交絡処理とは、多数の噴射孔から水流を噴出させ、これを二層ウェブに貫通させると、水流のエネルギーが各繊維の運動エネルギーに変換され、この運動エネルギーによって各繊維相互間が交絡する。特に、合成繊維層ウェブと親水性繊維層ウェブの層間では、疎水性繊維、熱接着性繊維及び親水性繊維の各繊維相互間が交絡する。 The hydrophobic fiber, the heat-adhesive fiber, and the hydrophilic fiber used when forming each fiber web of the synthetic fiber layer web and the hydrophilic fiber layer web are as described above. In order to form a synthetic fiber layer web, hydrophobic fibers and heat-adhesive fibers are uniformly mixed (mixed cotton), then opened by a spreader such as a card machine, and formed into a sheet. Moreover, in order to form a hydrophilic fiber layer web, the hydrophilic fibers may be opened by a spreader such as a card machine, and the sheet may be formed into a sheet. And after laminating | stacking a synthetic fiber layer web and a hydrophilic fiber layer web and obtaining a two-layer web, a hydroentanglement process is given to this two-layer web, and each fiber is entangled and a fiber fleece is obtained. Hydroentanglement treatment means that when a water flow is ejected from a large number of injection holes and penetrates through a two-layer web, the energy of the water flow is converted into the kinetic energy of each fiber, and the fibers are entangled by this kinetic energy. . In particular, between the synthetic fiber layer web and the hydrophilic fiber layer web, the fibers of the hydrophobic fiber, the heat-bonding fiber, and the hydrophilic fiber are entangled with each other.
得られた繊維フリースは、一対の加熱された凹凸ロール間に通される。これによって、熱接着性繊維が軟化又は溶融して、合成繊維層ウェブ中では疎水性繊維と熱接着性繊維の各繊維相互間が結合されると共に、凹凸ロールに対応した凹凸模様が合成繊維層ウェブの表面に施される。また、合成繊維層ウェブと親水性繊維層ウェブの層間では、疎水性繊維、熱接着性繊維及び親水性繊維の各繊維相互間も結合され、本発明に係る拭き布が得られる。ここで、一対の加熱された凹凸ロールの表面形状は、合成繊維層ウェブの表面に凹凸模様が施されるものであれば、どのようなものであってもよい。一般的には、一方の凹凸ロールの凸部が他方の凹凸ロールの凹部に対応し、一方の凹凸ロールの凹部が他方の凹凸ロールの凸部に対応して、噛み合って回転する一対の凹凸ロールを採用するのが好ましい。この場合、親水性繊維層ウェブの表面にも、凹凸ロールに対応した凹凸模様が施される。なお、凹凸ロールの加熱温度は、ロール表面の温度で、熱接着性繊維を軟化又は溶融せしめる程度でよい。 The obtained fiber fleece is passed between a pair of heated uneven rolls. As a result, the heat-adhesive fibers are softened or melted, and the fibers of the hydrophobic fibers and the heat-adhesive fibers are bonded to each other in the synthetic fiber layer web, and the uneven pattern corresponding to the uneven roll is formed in the synthetic fiber layer. Applied to the surface of the web. Further, between the synthetic fiber layer web and the hydrophilic fiber layer web, the fibers of the hydrophobic fiber, the heat-adhesive fiber and the hydrophilic fiber are also bonded to each other, and the wipe according to the present invention is obtained. Here, the surface shape of the pair of heated concavo-convex rolls may be anything as long as the concavo-convex pattern is provided on the surface of the synthetic fiber layer web. In general, a pair of concavo-convex rolls that are engaged and rotated so that a convex portion of one concave-convex roll corresponds to a concave portion of the other concave-convex roll and a concave portion of one concave-convex roll corresponds to a convex portion of the other concave-convex roll. Is preferably adopted. In this case, the surface of the hydrophilic fiber layer web is also provided with an uneven pattern corresponding to the uneven roll. In addition, the heating temperature of the uneven roll may be such that the temperature of the roll surface softens or melts the heat-adhesive fiber.
上記した本発明に係る拭き布の代表的な製造方法では、各繊維相互間を交絡させる方法として、水流交絡処理を用いたが、その他のニードルパンチ処理などで交絡させてもよい。また、合成繊維ウェブ層及び親水性繊維ウェブ層の両表面に凹凸模様が施されるようにしたが、合成繊維ウェブ層の表面にのみ凹凸模様が施されるようにしてもよい。さらに、一対の凹凸ロールに通した時点で、熱接着性繊維が軟化又は溶融するようにしたが、凹凸ロールに通す前に、熱接着性繊維を軟化又は溶融させ、各繊維相互間を結合させておいてもよい。たとえば、凹凸ロールに通す前に、二層ウェブを熱風中に通したり、加熱された一対の平滑ロール間に通せばよい。 In the representative manufacturing method of the wiping cloth according to the present invention described above, hydroentanglement treatment is used as a method of entanglement between fibers, but entanglement may be performed by other needle punch treatment or the like. In addition, although the concave and convex pattern is provided on both surfaces of the synthetic fiber web layer and the hydrophilic fiber web layer, the concave and convex pattern may be provided only on the surface of the synthetic fiber web layer. Furthermore, the heat-adhesive fibers are softened or melted when passed through a pair of concave and convex rolls, but before passing through the concave-convex rolls, the heat-adhesive fibers are softened or melted to bond the fibers together. You may keep it. For example, before passing through the uneven roll, the two-layer web may be passed through hot air or between a pair of heated smooth rolls.
以上説明した本発明に係る拭き布は、主として台所回りの油汚れなどを掻き取って除去するのに、好適に使用される。本発明に係る拭き布の使用法は、当該拭き布に水をある程度含浸させ、合成繊維層を拭き取り面として、油汚れなどを擦る。この際、本発明に係る拭き布は、各構成繊維相互間が交絡し、且つ、熱接着性繊維の軟化又は溶融によって結合しているため、水に浸漬して水を含浸させても、合成繊維層表面の凹凸模様は、消失しないものである。したがって、拭き布の主に親水性繊維層に含浸された水が、合成繊維層を通って油汚れなどに供給され、油汚れなどを軟化させると共に、合成繊維層に設けられた凹凸模様の凸部によって、油汚れなどが掻き取られ、これを良好に除去することができるのである。なお、本発明に係る拭き布は、台所回りの油汚れなどの除去だけでなく、その他の各種汚れをも良好に除去しうるものである。 The wiping cloth according to the present invention described above is suitably used mainly for scraping and removing oil stains around the kitchen. The method of using the wiping cloth according to the present invention involves impregnating the wiping cloth with water to some extent and rubbing oil stains or the like using the synthetic fiber layer as a wiping surface. At this time, since the wiping cloth according to the present invention is entangled between the constituent fibers and bonded by the softening or melting of the heat-adhesive fibers, it can be synthesized even if immersed in water and impregnated with water. The uneven pattern on the surface of the fiber layer does not disappear. Accordingly, water impregnated mainly in the hydrophilic fiber layer of the wiping cloth is supplied to the oil stains through the synthetic fiber layer, softening the oil stains and the like, and the uneven pattern provided on the synthetic fiber layer. Oil stains and the like are scraped off by the portion and can be removed satisfactorily. In addition, the wiping cloth which concerns on this invention can remove not only the oil stains around a kitchen, but other various stains satisfactorily.
本発明に係る拭き布は、上記した構成を持つため、以下のような効果を奏する。
（ｉ）拭き布の合成繊維層は、疎水性繊維と熱接着性繊維の各繊維相互間が交絡すると共に熱接着性繊維によって結合した状態となっており、且つ、その表面に凹凸模様が設けられている。すなわち、各繊維間の交絡と結合によって凹凸模様が施されており、しかも疎水性繊維は水を吸収しにくく膨潤して軟化しにくいものであるため、水を含浸させて使用しても、凹凸模様の凸部は消失しにくくなっている。したがって、拭き布の凸部の作用で、油汚れなどを良好に掻き取ることができる。
（ii）拭き布の使用時において、水が含浸された親水性繊維層から、合成繊維層を通って、水が拭き取り面に供給される。したがって、油汚れなどに水が供給され、油汚れなどを軟化させうるため、拭き布の凸部の作用と相俟って、油汚れなどを良好に掻き取ることができる。
（iii ）拭き取り面となる合成繊維層には、繊度が５デニール以上の比較的剛性の大きい疎水性繊維が含まれている。疎水性繊維は、親水性繊維層から供給される水と接触しても、それを吸収しにくいため、その剛性が低下しにくい。したがって、大きな剛性を持つ疎水性繊維によって、油汚れなどを良好に掻き取ることができる。
Since the wiping cloth according to the present invention has the above-described configuration, the following effects can be obtained.
(I) The synthetic fiber layer of the wiping cloth is in a state in which the fibers of the hydrophobic fiber and the heat-adhesive fiber are entangled with each other and bonded by the heat-adhesive fiber, and an uneven pattern is provided on the surface thereof. It has been. In other words, the concavo-convex pattern is given by the entanglement and bonding between the fibers, and the hydrophobic fiber is difficult to absorb water and swell and soften. The convex part of the pattern is difficult to disappear. Therefore, oil stains and the like can be scraped off satisfactorily by the action of the convex portion of the wiping cloth.
(Ii) When using the wiping cloth, water is supplied to the wiping surface from the hydrophilic fiber layer impregnated with water through the synthetic fiber layer. Accordingly, water is supplied to the oil stain and the like, and the oil stain can be softened. Therefore, in combination with the action of the convex portion of the wiping cloth, the oil stain can be scraped off satisfactorily.
(Iii) The synthetic fiber layer serving as the wiping surface contains hydrophobic fibers having a relatively high rigidity having a fineness of 5 denier or more. Even if the hydrophobic fiber comes into contact with water supplied from the hydrophilic fiber layer, it is difficult to absorb the hydrophobic fiber, so that its rigidity is not easily lowered. Therefore, oil stains and the like can be scraped off satisfactorily by the hydrophobic fibers having large rigidity.
以下、実施例に基づいて本発明を説明するが、本発明は実施例に限定されるものではない。本発明は、特定の合成繊維層と特定の親水性繊維層との二層構造物の合成繊維層表面に、各繊維相互間の交絡と結合により、その形態が維持された凹凸模様を設ければ、油汚れなどを良好に除去しうる拭き布が得られるとの知見に基づくものとして、解釈されるべきである。 EXAMPLES Hereinafter, although this invention is demonstrated based on an Example, this invention is not limited to an Example. In the present invention, the surface of the synthetic fiber layer of the two-layer structure of the specific synthetic fiber layer and the specific hydrophilic fiber layer is provided with a concavo-convex pattern whose shape is maintained by entanglement and bonding between the fibers. For example, it should be interpreted as being based on the knowledge that a wiping cloth capable of satisfactorily removing oil stains can be obtained.

That is, salad oil (about 20 cc) is put in a crucible and heated with a burner. When heated for about one and a half hours to two hours, the viscosity of the salad oil increases rapidly. After heating for about another 10 minutes from the time when the viscosity is increased, the oil is naturally cooled away from the fire to prepare an oxidized oil.
Each sample was wetted with water, squeezed tightly, held with a fingertip, and scraped off the applied oxidized oil 10 times in a reciprocating manner so that the pressure was as constant as possible. About each sample which concerns on Examples 1-3 and Comparative Examples 1-3, the synthetic fiber layer was made into the wiping surface, and about the sample which concerns on the comparative example 4, the arbitrary one surface was made into the wiping surface, and the scraping operation | work was performed. .

実施例１〜３に係る拭き布は、塗布した酸化油を良好に掻き取ることができ、また掻き取り作業に伴って多数の毛羽が発生することもなかった。また、被拭き取り面に拭き布に含浸された水が多量に付着することもなかった。一方、比較例１に係る拭き布は、合成繊維層に熱接着性繊維が含有されていないため、各繊維相互間の結合が不十分で、掻き取り作業に伴い、非常に多数の毛羽が、合成繊維層表面に発生した。したがって、繰り返し使用すると、汚れ除去性も低下し、液残りもしやすくなり、使用しにくいものであった。また、比較例２に係る拭き布は、合成繊維層中の疎水性繊維の繊度が低く、そのため疎水性繊維の剛性が不十分で、塗布した酸化油を良好に掻き取ることができなかった。比較例３に係る拭き布は、合成繊維層面に凹凸模様が存在しないため、塗布した酸化油の掻き取り性が十分に向上せず、合成繊維層表面全体で掻き取ることになるので、非常に多数の毛羽が発生した。また、比較例４に係る拭き布は、二層構造となってならず、拭き取り面にも親水性繊維が５０質量％程度存在するため、被拭き取り面に非常に多量の水が付着した。 The wipes according to Examples 1 to 3 were able to scrape the applied oxidized oil satisfactorily, and a large number of fluff was not generated with the scraping operation. Further, a large amount of water impregnated in the wiping cloth did not adhere to the surface to be wiped. On the other hand, the wiping cloth according to Comparative Example 1 does not contain thermal adhesive fibers in the synthetic fiber layer, and thus the bonding between the fibers is insufficient. It occurred on the surface of the synthetic fiber layer. Therefore, when used repeatedly, the stain removability is lowered and the liquid remains easily, which is difficult to use. Moreover, the wipe which concerns on the comparative example 2 had the low fineness of the hydrophobic fiber in a synthetic fiber layer, therefore, the rigidity of the hydrophobic fiber was inadequate and the applied oxidized oil was not able to be scraped off favorably. Since the wiping cloth according to Comparative Example 3 has no uneven pattern on the surface of the synthetic fiber layer, the scraping property of the applied oxidized oil is not sufficiently improved, and the entire surface of the synthetic fiber layer is scraped off. Numerous fluff was generated. Further, the wiping cloth according to Comparative Example 4 did not have a two-layer structure, and hydrophilic fibers were present on the wiping surface in an amount of about 50% by mass, so that a very large amount of water adhered to the wiping surface.
