The present invention relates to a nonwoven fabric for flooring that has excellent sound insulation and sound insulation properties and is suitable as a cushioning member for flooring.
一戸建住宅やマンションなどの集合住宅の床材としては
、樹脂タイル、畳、カーペット、木質系床材等が使われ

く、掃除がし易く、清潔であるため、近年、新築時のみ
なすリフォーム時にもその需要が増加している。Resin tiles, tatami mats, carpets, wood flooring, etc. are used as flooring materials for single-family homes and apartment complexes such as condominiums, but wood flooring materials do not have to worry about dust mites and are easy to clean. Because they are easy to remove and clean, demand for them has increased in recent years, both during new construction and renovations.
ところで、床材の施工に際しては、騒音が階下へ伝わら

構造にしたりするなどして軽衝撃音の伝搬を防止するこ
とが種々試みられている。By the way, when installing flooring materials, consideration must be given to preventing noise from being transmitted downstairs. Such floor noises include heavy impact sounds caused by children jumping or running around, and light impact sounds caused by chairs being dragged or spoons falling. The degree to which heavy impact sound is transmitted is
Although it mainly depends on the basic structure of the building, the degree to which light impact sound is transmitted also greatly depends on the material and structure of the flooring. Therefore, various attempts have been made in the past to prevent the propagation of light impact sounds, such as by using cushioning members in the floor material or by making the floor have a special structure.
例えば、木質系床材の直貼り床（厚みが薄く、直接コン
クリートスラブ等に貼る床、総床厚１０〜３０ｍｍ）の
場合には、緩衝部材として１層構造のゴム発泡体やフェ

また、支持脚付きパネルを使用した二重床（総床厚１５

総床厚７０〜１６０ｍｍ）等のように緩衝部材を使用し
た下地付構造の床も提案されている。In addition, a double floor using panels with supporting legs (total floor thickness 15
0-210 mm), using foamed plastic panels and foamed plastic floors (total floor thickness 70-160m)
m) or a floating floor using special glass wool mats (
Floors with a base structure using cushioning members, such as those with a total floor thickness of 70 to 160 mm, have also been proposed.
しかしなから、従来の下地付構造の床は、遮音性・防音

、ドアや窓の床面が上かって開口部の高さか低くなると
いう欠点があった。特に、リフォーム時には、床面が上
がるためにドアの取り替えなどを強いられるということ
か問題となっていた。However, conventional floors with a base structure have either relatively good sound insulation properties or have the drawback of being expensive. Another disadvantage is that skill is often required to construct a floor with a base structure. Furthermore, since the floor of this type of underlay structure is thick, there is a drawback that the floor surface of the door or window is raised and the height of the opening is lowered. This has been a particular problem during renovations, as the floor level has been raised and doors have been forced to be replaced.
一方、直貼り床において従来の緩衝部材を使用したもの

すきなどが生し易いという欠点も伴なっていた。On the other hand, directly bonded floors using conventional cushioning members are generally low in cost, but have the disadvantage that they do not have sufficient sound insulation or soundproofing effects. In response to this, some attempts have been made to increase the thickness of cushioning materials such as rubber foam, but in this case, the cost increases and the disadvantage is that the floor is prone to warping, dents, and gaps. It had become.
この発明は以上のような従来技術の問題点を解決しよう
とするものであり、床材用緩衝部材として、軽衝撃音を
低コストで効果的に遮音・防音することのできる床材用
不織布を提供することを目的としている。This invention aims to solve the problems of the prior art as described above, and provides a nonwoven fabric for flooring that can effectively insulate and soundproof light impact sounds at low cost, as a cushioning member for flooring. is intended to provide.
この発明者は、不織布の繊維素材として特定のものを使

目的が達成できることを見出し、この発明を完成させた
。The inventor discovered that the above object could be achieved by using a specific fiber material for the nonwoven fabric and forming the nonwoven fabric's area weight and apparent density within a specific range by needle punching and heat fusion. , completed this invention.
すなわち、この発明は、熱融着繊維を配合した、太さ３

／ｃｍ３１．：形成したことを特徴とする床材用不織布
を提供する。In other words, the present invention provides a fiber with a thickness of 3 that contains heat-fusible fibers.
By laminating card webs made of fibers of 0 to 50 denier, needle punching and heat fusion, the fabric weight is 2.
00~500g/m2, apparent density 0.02~0.2g
/cm31. : To provide a nonwoven fabric for flooring, characterized by the following:
以下、この発明の詳細な説明する。The present invention will be explained in detail below.
この発明の床材用不織布の繊維素材としては、繊維の太

有効に遮音・防音することが可能となる。As the fiber material for the nonwoven fabric for flooring of the present invention, those having a fiber thickness of 30 to 50 deniers are used. By using such thick fibers, it is possible to improve the sound absorption characteristics in the low frequency range of light impact sounds, and it becomes possible to effectively insulate and soundproof the area before normal daily life.
３０デニ一ル未満の細い繊維を使用すると軽衝撃音の吸

ウェブの均斉度が低下し好ましくない。If thin fibers of less than 30 denier are used, the sound absorption properties for light impact sounds will be reduced. In addition, the flexibility of the nonwoven fabric increases,
This is not preferable because the load capacity (sinking when walking, etc.) will be excessive. Furthermore, the machinability is also reduced, and the so-called "stringing phenomenon" that occurs when the nonwoven fabric is cut when cutting the nonwoven fabric at a flooring construction site also becomes a problem. On the other hand, if the thickness exceeds 50 deniers, the uniformity of the web decreases, which is not preferable.

に対するへたりが減少し、また十分な機械的強度も有す
るようになるので床材用部材として好適なものとなる。Further, the fibers of the carded web are blended with heat-fusible fibers. From the viewpoint of adhesive strength, the heat-fusible fibers are preferably blended with polyester-based fusible fibers, polyamide F-based fusible fibers, or the like. Although the blending ratio depends on the type of fiber used, it is usually preferably 10 to 30% by weight. This improves the modulus of elasticity of the nonwoven fabric, reduces settling under repeated loads, and provides sufficient mechanical strength, making it suitable for use as a flooring member.
一方、熱融着繊維の配合率を１０重量％未満とすると、
積層したカードウェブの層間の剥離強度か弱くなるので
好ましくない。また、３０重量％よりも多（すると不織
布が硬くなり、遮音性が低下するので好ましくない。On the other hand, if the blending ratio of heat-fusible fiber is less than 10% by weight,
This is not preferable because the peel strength between the layers of the laminated card web becomes weak. Moreover, if the amount is more than 30% by weight, the nonwoven fabric becomes hard and the sound insulation properties decrease, which is not preferable.

い。The nonwoven fabric for flooring of the present invention is produced by laminating card webs made of the above-described fiber materials, needle punching and heat-sealing them, and having a basis weight of 200 to 500 g/m2 and an apparent density of 0.
02 to 0.2 g/rn3. If the apparent density is made higher than 0.2 g/cm" to make the nonwoven fabric hard, the sound absorption properties will decrease, which is undesirable. On the other hand, if the apparent density is made lower than 0.02 g/7" cm3, the nonwoven fabric When the flexibility of the material is increased, the loadability increases, making it unsuitable for use as a flooring member. Furthermore, stringing phenomenon also becomes a problem at construction sites. Also, increase the basis weight to 5
If the value exceeds 00 g/m2, the thickness of the nonwoven fabric becomes too large in order to keep the apparent density within the above-mentioned preferred range, which is undesirable because it reduces its usefulness as a flooring material. -If the force and basis weight are less than 200 g/m2, the function as a buffer H will deteriorate, which is not preferable.
不織布をこのような目付量や密度の範囲に形成すること
により、その厚さを約１〜ｉＱｍｍに仕上げ、軽衝撃前
に対する吸音性を高くし、かつ床材として適度な載荷性
も有し、切削性も良好なものとすることか可能となる。By forming the nonwoven fabric in such a range of basis weight and density, the thickness is finished to about 1 to iQmm, and it has high sound absorption properties before a light impact, and has a suitable load capacity as a flooring material. It is also possible to improve machinability.

布を通り抜は易くなり、不織布の遮音性か低下する。こ
れに対し、て、ニードルパンチ後に軌融着し。A nonwoven fabric having such a basis weight and density can be obtained by needle punching a laminated card web under appropriate punching conditions. It is assumed that it was formed by That is, when a needle bunch is used to form a nonwoven fabric, the number of fibers oriented in the longitudinal direction (direction perpendicular to the woven surface of the fabric) increases in the nonwoven fabric. Therefore, sound easily passes through the nonwoven fabric, and the sound insulation properties of the nonwoven fabric deteriorate. On the other hand, the track fused after needle punching.

たカードウェブの層間剥離強度を高くすることも可能と
なる。When a non-woven fabric is formed by using a non-woven fabric, the needle punching conditions for maintaining the laminated card web as a non-woven fabric can be relaxed, so that the number of longitudinally oriented fibers can be reduced to a minimum. Furthermore, since sound propagates in the direction of the fused surface and is attenuated, it is possible to further improve sound insulation and soundproofing properties. Furthermore, it is also possible to increase the interlayer peel strength of the laminated card web.
熱融着の条件としては、カードウェブを構成する繊維の
種類、熱融着繊維の配合率、ニードルパンチ条件等にも
よるか、通常は温度１５０〜１８０℃で融着したものが
好ましい。The conditions for heat fusing depend on the type of fibers constituting the card web, the blending ratio of heat fusing fibers, needle punch conditions, etc., but it is usually preferable to fuse at a temperature of 150 to 180°C.
なお、積層するカードウェブの層数は、デニール構成、
フリース目付等にもよるが、従来品の１０〜２０層に対

しい。これにより吸音・遮音性を向上させることができ
る。The number of layers of card web to be laminated depends on the denier configuration,
Although it depends on the fleece weight etc., it is preferable to have a multi-layered structure, for example, 30-40 layers, compared to the 10-20 layers of conventional products. Thereby, sound absorption and sound insulation properties can be improved.
この発明の床材用不織布は、以上のような不織布からな
るが、更にそのような不織布に遮水・遮湿性層をラミネ
ートしたものとすることもてきる。The nonwoven fabric for flooring of the present invention is made of the above-mentioned nonwoven fabric, but it can also be made by laminating such a nonwoven fabric with a water-blocking/moisture-blocking layer.

からの湿気の侵入を防止することが可能となる。As a result, even when a non-woven fabric for flooring is provided on a base material that is prone to moisture, such as concrete, a water- and moisture-blocking layer can be interposed between the base material and the non-woven fabric, making it easy to remove moisture from the base material. It is possible to prevent moisture from entering.

A water-blocking/moisture-blocking polymer film, a water-blocking/moisture-blocking polymer foam sheet, etc. can be preferably used. As the water-shielding/moisture-shielding polymer film, for example, a hot melt film of polyolefin, polyamide, etc. can be used. Further, in order to laminate such a film to a nonwoven fabric, an adhesive such as an epoxy adhesive or a chloroprene adhesive may be used.
