Description

本発明は、例えば床敷物等として使用される、クッション性、保温性、防音性に優れたタフテッドカーペットに関するものである。なお、本発明で使われる見かけ厚みとは、自然な状態でゲージをあてて測定した厚みをいう。   The present invention relates to a tufted carpet having excellent cushioning properties, heat retaining properties, and soundproofing properties, for example, used as a floor covering. The apparent thickness used in the present invention means a thickness measured by applying a gauge in a natural state.

従来から、タフテッドカーペット用基布にパイル糸がタフティング機によって植設されたタフテッド原反の裏面に、樹脂又はゴムラテックスを塗布して形成される接着剤層を介して不織布(2次基布)が貼り合わされた構成のタフテッドカーペットはよく知られている。さらに、前記不織布(2次基布)に厚みのある不織布(見かけ厚みが1〜10mm)を使用し、クッション性、保温性、防音性に優れたタフテッドカーペットが得られることは公知となっている。しかしながら、厚みのある不織布を貼り合わす場合、不織布の通気性が著しく悪いため、樹脂又はゴムラテックスを塗布して形成される接着剤層の乾燥効率が極端に低下し、生産性の悪いものとなっていた。   Conventionally, a nonwoven fabric (secondary substrate) is formed through an adhesive layer formed by applying resin or rubber latex on the back of a tufted original fabric in which pile yarn is planted on a tufted carpet base fabric by a tufting machine. A tufted carpet having a structure in which a cloth is bonded is well known. Furthermore, it is publicly known that a thick non-woven fabric (apparent thickness is 1 to 10 mm) is used for the non-woven fabric (secondary base fabric), and a tufted carpet excellent in cushioning property, heat retaining property and soundproofing property can be obtained. Yes. However, when pasting a thick nonwoven fabric, the breathability of the nonwoven fabric is remarkably poor, so that the drying efficiency of the adhesive layer formed by applying a resin or rubber latex is extremely lowered, resulting in poor productivity. It was.

この課題を解決するために、例えば、特許文献1においては、厚みのある不織布(2次基布)を構成する合成繊維の太さを20〜60dtexにすることによって通気性を改善し、接着剤層の乾燥効率が落ちることを防ぐ方法が提案されている。   In order to solve this problem, for example, in Patent Document 1, air permeability is improved by setting the thickness of a synthetic fiber constituting a thick nonwoven fabric (secondary base fabric) to 20 to 60 dtex, and an adhesive. Methods have been proposed to prevent the drying efficiency of the layer from falling.

また、特許文献2においては、厚みのある不織布(2次基布)を構成する合成繊維のうち30重量%以上を22〜88dtexの極太繊維とすることにより、乾燥効率が改善され、保温性、防音性、クッション性に優れたタフテッドカーペットが提供されている。   Moreover, in patent document 2, by making 30 weight% or more out of the synthetic fiber which comprises a thick nonwoven fabric (secondary base fabric) into 22-88 dtex very thick fiber, drying efficiency is improved, heat retention, Tufted carpets with excellent soundproofing and cushioning properties are provided.

また、特許文献3においては、厚みのある不織布(2次基布)の全面に貫通孔を穿設することにより接着剤層の乾燥効率を向上し、厚みが厚くなるほど起こりやすい層内剥離の問題も解決する技術が開示されている。

Moreover, in patent document 3, the drying efficiency of an adhesive bond layer is improved by making a through-hole in the whole surface of a thick nonwoven fabric (secondary base fabric), and the problem of delamination that easily occurs as the thickness increases. A technique for solving this problem is also disclosed.

しかしながら、上述のような方法で、不織布(2次基布)に厚みのある不織布を使用しても、従来よりも確かに改善された乾燥効率とはなるものの、通常のタフテッドカーペットの加工時のように、薄い不織布や織基布を2次基布として使用したときのような短時間で接着剤層の乾燥を実施することは難しく、更なる改善が望まれていた。本発明は、かかる技術的背景に鑑みてなされたものであって、保温性、防音性、クッション性を付与するために厚みのある不織布を使用しても、乾燥効率の低下を招かないタフテッドカーペットの製造方法およびタフテッドカーペットを提供することを課題とする。   However, even when a thick nonwoven fabric (secondary base fabric) is used for the nonwoven fabric (secondary base fabric) as described above, the drying efficiency is certainly improved compared to the conventional method, but when processing a normal tufted carpet. As described above, it is difficult to dry the adhesive layer in a short time as when a thin non-woven fabric or woven base fabric is used as the secondary base fabric, and further improvement has been desired. The present invention has been made in view of such a technical background, and is tufted that does not cause a decrease in drying efficiency even when a thick nonwoven fabric is used to impart heat retention, soundproofing, and cushioning properties. It is an object to provide a method for manufacturing a carpet and a tufted carpet.

本発明者らは、このような課題を解決するために鋭意検討の結果、厚みのある基布にパイル糸を植設することによって、乾燥効率の良好な、保温性、防音性、クッション性に優れたタフテッドカーペットが得られることを見出し、本発明に到達した。上記課題を達成するために、本発明は以下の手段を提供する。   As a result of intensive studies to solve such problems, the present inventors have achieved good drying efficiency, heat retention, soundproofing, and cushioning properties by planting pile yarn on a thick base fabric. The present inventors have found that an excellent tufted carpet can be obtained and have reached the present invention. In order to achieve the above object, the present invention provides the following means.

[1]パイル糸と基布と接着剤層からなるタフテッドカーペットにおいて、基布として少なくとも目付けが50〜500g/mで見かけ厚みが1〜10mmの不織布からなる基布にパイル糸を植設したことに特徴のある防音カーペット。 [1] In a tufted carpet composed of pile yarn, base fabric, and adhesive layer, pile yarn is planted on a base fabric composed of a nonwoven fabric having a basis weight of at least 50 to 500 g / m 2 and an apparent thickness of 1 to 10 mm. A soundproof carpet that has a distinctive feature.

[2]前記基布として、目付けが50〜500g/mで見かけ厚みが1〜10mmの不織布と、目付けが50〜150g/mで見かけ厚みが0.3〜1.0mmのタフテッドカーペット用1st基布を重ねた基布にパイル糸を植設したことに特徴のある防音カーペット。 [2] As the base fabric, a nonwoven fabric having a basis weight of 50 to 500 g / m 2 and an apparent thickness of 1 to 10 mm, and a tufted carpet having a basis weight of 50 to 150 g / m 2 and an apparent thickness of 0.3 to 1.0 mm A soundproof carpet characterized in that pile yarns are planted on a base fabric with a 1st base fabric overlaid.

[4]二枚以上の基布を同時にタフテッド機に供給し、前記二枚以上の基布を重ねた見かけ厚みが1〜10mmである基布にパイル糸を植設することに特徴のある防音カーペットの製造方法。   [4] Soundproofing characterized in that two or more base fabrics are simultaneously supplied to a tufted machine, and pile yarn is planted on the base fabric having an apparent thickness of 1 to 10 mm obtained by stacking the two or more base fabrics. Carpet manufacturing method.

[1]の発明では、基布として少なくとも目付けが50〜500g/mで見かけ厚みが1〜10mmの不織布からなる基布にパイル糸を植設しているので、保温性、防音性、クッション性に優れたタフテッドカーペットが得られ、しかも、見かけ厚みが1〜10mmである基布にパイル糸を直接植設しているので、カーペット表皮層の裏面に通常のバッキング加工をすることができ、乾燥効率の低下を来すことは無い。 In the invention [1], since at least the basis weight as the base fabric thickness apparent at 50 to 500 g / m 2 are implanted pile yarn based fabric comprising a nonwoven fabric of 1 to 10 mm, warmth, sound insulation, cushioning A tufted carpet with excellent properties can be obtained, and pile yarn is directly planted on a base fabric with an apparent thickness of 1 to 10 mm, so that the normal backing can be applied to the back of the carpet skin layer. There is no reduction in drying efficiency.

[2]の発明では、基布として、クッション性のある目付けが50〜500g/mで見かけ厚みが1〜10mmの不織布と、目付けが50〜150g/mで見かけ厚みが0.3〜1.0mmのタフテッドカーペット用1st基布を重ねたものとするので、別工程でクッション性のある不織布とタフテッドカーペット用1st基布を張り合わさなくても、パイル糸と二枚の基布を同時に一体化したカーペット表皮層とすることができる。また、カーペット表皮層の裏面にそのままバッキング加工することができるので、乾燥効率の低下を招くことは無い。 In the invention of [2], as the base fabric, a nonwoven fabric having a cushioning basis weight of 50 to 500 g / m 2 and an apparent thickness of 1 to 10 mm, and a basis weight of 50 to 150 g / m 2 and an apparent thickness of 0.3 to Since 1st base fabric for tufted carpet of 1.0 mm is piled up, pile yarn and two base fabrics can be used without attaching cushioning nonwoven fabric and 1st base fabric for tufted carpet in a separate process. The carpet skin layer can be integrated at the same time. Moreover, since the backing process can be performed on the back surface of the carpet skin layer as it is, the drying efficiency is not reduced.

[3]の発明では、パイル糸と基布と接着剤層からなるタフテッドカーペットにおいて、基布として少なくとも目付けが50〜500g/mで見かけ厚みが1〜10mmの不織布からなる基布にパイル糸を植設してカーペット原反とし、その裏面に直接バッキング加工をすることができるので、通常のバッキング加工と同様な乾燥効率とすることができる防音カーペットの製造方法とすることができる。 In the invention of [3], in a tufted carpet composed of pile yarn, a base fabric and an adhesive layer, the base fabric is piled on a base fabric composed of a nonwoven fabric having a basis weight of at least 50 to 500 g / m 2 and an apparent thickness of 1 to 10 mm. Since the yarn can be planted to make the carpet, and the back surface thereof can be directly backed, so that a method for producing a soundproof carpet that can achieve the same drying efficiency as that of a normal backing can be obtained.

[4]の発明では、二枚以上の基布を同時にタフテッド機に供給し、二枚以上の基布を重ねた状態でパイル糸を植設するので、二枚以上の基布を別工程で張り合わせた状態にする必要がなく、また、前記二枚以上の基布を重ねた見かけ厚みが1〜10mmであるので保温性、防音性に優れるのみならず、クッション性にも優れた歩行感の良いカーペットとすることができ、乾燥効率の良好な防音カーペットの製造方法とすることができる。   In the invention of [4], two or more base fabrics are simultaneously supplied to the tufted machine, and pile yarns are planted in a state where the two or more base fabrics are stacked, so that two or more base fabrics are separated in a separate process. There is no need to put them together, and since the apparent thickness of the two or more base fabrics is 1 to 10 mm, it not only has excellent heat and sound insulation properties, but also has excellent cushioning. It can be set as a good carpet, and it can be set as the manufacturing method of the soundproof carpet with favorable drying efficiency.

次に、この発明に係る防音カーペットの一実施形態を図面に基づいて説明する。この実施形態の防音カーペット1は、パイル糸2と厚みのある基布3からなる表皮層4の裏面に接着剤層5を塗布し乾燥することによってパイル糸2と基布3が固定される。(図1参照)   Next, an embodiment of a soundproof carpet according to the present invention will be described with reference to the drawings. In the soundproof carpet 1 of this embodiment, the pile yarn 2 and the base fabric 3 are fixed by applying the adhesive layer 5 to the back surface of the skin layer 4 composed of the pile yarn 2 and the thick base fabric 3 and drying it. (See Figure 1)

また、別の実施形態としては、厚みのある基布3とタフテッドカーペット用1st基布6を重ねた基布にパイル糸2が植設され表皮層4を形成し、接着剤層5によってパイル糸2と基布が固定されている。(図2参照)   In another embodiment, pile yarns 2 are planted on a base fabric in which a thick base fabric 3 and a 1st base fabric 6 for tufted carpet are overlapped to form a skin layer 4. The thread 2 and the base fabric are fixed. (See Figure 2)

パイル糸2としての素材は、どのようなものでもよく、例えば素材としては、ポリエステル系繊維、ポリアミド系繊維、ポリオレフィン系繊維等の熱可塑性繊維、またこれら各繊維の複合化繊維、アセテート等の半合成繊維、レーヨン等の再生繊維、麻、綿等の天然繊維、あるいはこれらの混綿したもの等が挙げられる。また、パイルの形態としては、カットパイルやループパイルでも良いし、カットパイルとループパイルが混合したものでもかまわない。   The material for the pile yarn 2 may be any material, for example, a thermoplastic fiber such as a polyester fiber, a polyamide fiber, or a polyolefin fiber, or a composite fiber of these fibers, a half of an acetate, or the like. Examples thereof include synthetic fibers, regenerated fibers such as rayon, natural fibers such as hemp and cotton, or a mixture of these. Further, as a form of the pile, a cut pile or a loop pile may be used, or a mixture of the cut pile and the loop pile may be used.

基布3は、目付けが50〜500g/mで見かけ厚みが1〜10mmの不織布からなる基布がよい。目付けが50g/mを下回ったり、見かけ厚みが1mmに達していなければ、適度なクッション性や防音性を得られない。また、目付けが500g/mを上回ったり、見かけ厚みが10mmを超えても、カーペットとしての取扱が困難になったり、徒にコストアップとなるだけに好ましくない。さらに防音性に好ましい目付けとしては、200〜500g/m、見かけ厚みが3〜10mm、またさらに好ましい目付けとしては、300〜500g/m、見かけ厚みが5〜10mmが好適である。基布としての素材は、どのようなものでもよく、例えば、ポリエステル系繊維、ポリアミド系繊維、ポリオレフィン系繊維等の熱可塑性繊維、またこれら各繊維の複合化繊維、アセテート等の半合成繊維、レーヨン等の再生繊維、麻、綿等の天然繊維、あるいはこれらの混綿したものが挙げられるが、中でもポリエステル系繊維やポリプロピレン系繊維の熱可塑性繊維が好ましい。また、融点の異なる熱可塑性繊維からなる不織布の表面を熱処理して繊維を強固に固定したものや、不織布の表面にバインダー樹脂を含浸させ繊維を固定した基布とすれば、パイル糸2をタフティング機で基布3に植設するときに、基布3の繊維がカーペット原反の表面に突き出ることが防がれることから、本発明の基布3としてはより好ましい。基布3の形態としては限定しないが、例えばスパンボント不織布、ニードルパンチ不織布、ウォターパンチ不織布等を挙げられる。 The base fabric 3 is preferably a base fabric made of a nonwoven fabric having a basis weight of 50 to 500 g / m 2 and an apparent thickness of 1 to 10 mm. If the basis weight is less than 50 g / m 2 or the apparent thickness does not reach 1 mm, appropriate cushioning and soundproofing properties cannot be obtained. Further, even if the basis weight exceeds 500 g / m 2 or the apparent thickness exceeds 10 mm, it is not preferable because handling as a carpet becomes difficult or the cost is increased. Furthermore, as a basis weight preferable for soundproofing, 200 to 500 g / m 2 and an apparent thickness of 3 to 10 mm are preferable, and as a more preferable basis weight, 300 to 500 g / m 2 and an apparent thickness of 5 to 10 mm are preferable. Any material may be used as the base fabric, for example, thermoplastic fibers such as polyester fibers, polyamide fibers, and polyolefin fibers, composite fibers of these fibers, semi-synthetic fibers such as acetate, and rayon. And the like, and natural fibers such as hemp and cotton, or a mixture of these, and among them, polyester fibers and polypropylene fibers are preferred. In addition, if the surface of a nonwoven fabric made of thermoplastic fibers having different melting points is heat-treated and the fiber is firmly fixed, or a base fabric in which the nonwoven fabric is impregnated with a binder resin and the fiber is fixed, the pile yarn 2 is tough. Since it is prevented that the fiber of the base fabric 3 protrudes to the surface of the carpet raw fabric when planted on the base fabric 3 with a tapping machine, it is more preferable as the base fabric 3 of the present invention. Although it does not limit as a form of the base fabric 3, For example, a spun bond nonwoven fabric, a needle punch nonwoven fabric, a water punch nonwoven fabric, etc. are mentioned.

また、別の形態として二枚の基布を重ねた状態でパイル糸を植設する場合は、前述のような基布3の表面処理を行なうことなくパイル糸2をタフティング機で基布に植設することができる。カーペット原反の裏面側に基布3を、パイル糸側にタフテッドカーペット用1st基布6となるように二枚の基布を重ね、二枚の基布を重ねた見かけ厚みが1〜10mmである基布にパイル糸を植設する。タフテッドカーペット用1st基布6としては、通常のタフテッドカーペットの1st基布として使われるものであればよい。例えば、テープヤーンからなる織基布やスパンボンド不織布等を例示できる。二枚の基布を重ねる方法は、図4のようにタフティング機の直前で重ね合わせればよい。別工程であらかじめ重ね合わせたものも使用することはできるが、工程が増加しコストアップにつながる。(図2、図4参照)   Further, when the pile yarn is planted in a state where two base fabrics are stacked as another form, the pile yarn 2 is applied to the base fabric by a tufting machine without performing the surface treatment of the base fabric 3 as described above. Can be planted. The base fabric 3 is placed on the back side of the carpet fabric, the two base fabrics are stacked on the pile yarn side to form the 1st base fabric 6 for tufted carpet, and the apparent thickness of the two base fabrics is 1-10 mm. Pile yarn is planted on the base fabric. As the 1st base fabric 6 for tufted carpet, what is necessary is just to be used as the 1st base fabric of a normal tufted carpet. For example, a woven base fabric made of tape yarn, a spunbond nonwoven fabric, or the like can be exemplified. The method of stacking two base fabrics may be performed just before the tufting machine as shown in FIG. Although it is possible to use a superposed layer in a separate process, the number of processes increases and the cost increases. (See Figs. 2 and 4)

また、本発明において、二枚以上の基布を重ねた状態でパイル糸を植設する場合、例えば図3のように通常の1st基布6と不織布3ともう一枚の通常の1st基布6をタフティング機にセットし、ニードル部で1st基布6の間に不織布3が挟まれるようにして、パイル糸を植設する。このような基布の構成にすることにより、図2の場合のように不織布3にパイル糸が沈み込まないようにすることができ、さらに耐久性に優れたタフテッドカーペットとすることができる。(図3参照)   In the present invention, when pile yarn is planted in a state where two or more base fabrics are stacked, for example, as shown in FIG. 3, a normal 1st base fabric 6, a nonwoven fabric 3, and another normal 1st base fabric. 6 is set in a tufting machine, and pile yarn is planted so that the nonwoven fabric 3 is sandwiched between the first base fabric 6 at the needle portion. By adopting such a base fabric configuration, the pile yarn can be prevented from sinking into the nonwoven fabric 3 as in the case of FIG. 2, and a tufted carpet having excellent durability can be obtained. (See Figure 3)

本発明においてタフティング機の設定をする場合、通常の設定値より基布が厚くなった量だけニードルの上下動の動作を大きくしたり、基布押さえ(プレッサーフート)を上に上げる必要がある。また、パイル長の設定においても、基布が厚くなった量だけ通常のパイル送りの糸量よりも多く供給量を増やしてやる必要がある。   When setting the tufting machine in the present invention, it is necessary to increase the up-and-down movement of the needle by the amount that the base fabric is thicker than the normal set value, or to raise the base fabric presser (presser foot) upward. . Also in setting the pile length, it is necessary to increase the supply amount by an amount that the base fabric is thicker than the yarn amount for normal pile feeding.

本発明で得られるタフテッドカーペットは、通常のタフテッドカーペットと比較して、厚みのある基布の内部にパイル糸が垂直方向に配列されていることから、さらなるクッション性の向上と、保温性、防音性に優れたタフテッドカーペットとすることができる。   The tufted carpet obtained according to the present invention has a further improvement in cushioning properties and heat-retaining properties because pile yarns are arranged in the vertical direction inside a thick base fabric as compared with a normal tufted carpet. The tufted carpet is excellent in soundproofing.

本発明における接着剤層はパイル糸2と基布3とを固定するために塗布される。接着剤層5としてはパイル糸2と基布3とを固定できる樹脂組成物やゴム組成物であれば特に限定されないが、例えば樹脂組成物の樹脂成分としてはアクリル系、ウレタン系、ポリ塩化ビニル、ポリエチレン、ポリプロピレン、エチレン−酢酸ビニル共重合体(EVA)等の樹脂が挙げられる。ゴム組成物のゴム成分としてはSBR(スチレン−ブタジエンゴム)、NBR(アクリロニトリル−ブタジエンゴム)、MBR(メチルメタクリレート−ブタジエンゴム)あるいは天然ゴム等が挙げられる。バッキング方法としてはロールコーティング法、スプレーコーティング法等でバッキング剤を塗布し乾燥すればよい。また、樹脂性フィルムからなる接着剤層5を直接表皮層4の裏面に溶融塗布し、パイル糸と基布とを固定してもよい。   The adhesive layer in the present invention is applied to fix the pile yarn 2 and the base fabric 3. The adhesive layer 5 is not particularly limited as long as it is a resin composition or a rubber composition that can fix the pile yarn 2 and the base fabric 3. For example, the resin component of the resin composition may be acrylic, urethane, or polyvinyl chloride. , Polyethylene, polypropylene, ethylene-vinyl acetate copolymer (EVA), and other resins. Examples of the rubber component of the rubber composition include SBR (styrene-butadiene rubber), NBR (acrylonitrile-butadiene rubber), MBR (methyl methacrylate-butadiene rubber), and natural rubber. As a backing method, a backing agent may be applied and dried by a roll coating method, a spray coating method, or the like. Alternatively, the adhesive layer 5 made of a resinous film may be melt-coated directly on the back surface of the skin layer 4 to fix the pile yarn and the base fabric.

さらに、接着剤層5の下側に、接着剤層5の保護や、さらなるクッション性、防音性の付与を目的に、織布や不織布からなる2nd基布を貼着させてもよい。形態としては、テープヤーン等からなる織基布や、スパンボント不織布、ニードルパンチ不織布、ウォターパンチ不織布等を挙げられる。素材としては、どのような素材のものでもよく、例えば、ポリエステル系繊維、ポリアミド系繊維、ポリオレフィン系繊維等の熱可塑性繊維、またこれら各繊維の複合化繊維、アセテート等の半合成繊維、レーヨン等の再生繊維、麻、綿等の天然繊維、あるいはこれらの混綿したものが挙げられる。   Further, a 2nd base fabric made of a woven fabric or a non-woven fabric may be attached to the lower side of the adhesive layer 5 for the purpose of protecting the adhesive layer 5 and providing further cushioning properties and soundproofing properties. Examples of the form include a woven base fabric made of tape yarn and the like, a spunbond nonwoven fabric, a needle punched nonwoven fabric, and a water punch nonwoven fabric. The material may be any material, for example, thermoplastic fibers such as polyester fibers, polyamide fibers, polyolefin fibers, composite fibers of these fibers, semi-synthetic fibers such as acetate, rayon, etc. Natural fibers such as hemp and cotton, or a mixture thereof.

実施例1において、接着剤層の下側に見かけ厚さ3mm、目付け200g/mのポリエステル繊維不織布層を積層し、さらにアクリル樹脂をスプレー塗布し滑り止め加工を施し防音カーペットを得た。防音性は遮音等級(L)が36で「○」、巻き取り性はやや角張ったところはあるものの問題なく巻くことができた。歩行感は実施例1より良好で5級と評価した。また、接着剤層と滑り止め加工の乾燥については130℃の条件下で11分間乾燥することで問題なく加工できた。
<Example 2>
In Example 1, a polyester fiber nonwoven fabric layer having an apparent thickness of 3 mm and a weight per unit area of 200 g / m 2 was laminated on the lower side of the adhesive layer, and further, an acrylic resin was applied by spraying to give a non-slip process to obtain a soundproof carpet. As for soundproofing, the sound insulation grade (L) was 36, and the winding property was slightly squared but could be wound without any problem. The walking sensation was better than Example 1 and was evaluated as 5th grade. Moreover, about the drying of an adhesive bond layer and a non-slip process, it was able to process without a problem by drying for 11 minutes on 130 degreeC conditions.

<実施例3>
実施例1において、ポリエステルのスパンボンド不織布(通常の1st基布 目付110g/m見かけ厚みが0.3mm)にポリエステルのニードルパンチ不織布(目付410g/m見かけ厚みが8mm)を重ね、さらにもう一枚のポリエステルのスパンボンド不織布(通常の1st基布 目付110g/m見かけ厚みが0.3mm)を重ね、三枚の基布が重なった基布とした以外は、実施例1と同様にして防音カーペットを得た。防音性は遮音等級(L)が37で「○」、巻き取り性はやや角張ったところはあるものの問題なく巻くことができた。歩行感は実施例1よりカーペットに腰があり5級と評価した。また、接着剤層の乾燥については全く問題なく良好であった。
<Example 3>
In Example 1, a polyester needle-punched non-woven fabric (410 g / m 2 basis weight is 8 mm) is layered on a polyester spunbonded non-woven fabric (ordinary 110 g / m 2 basis weight is 0.3 mm). superimposed single polyester spunbond nonwoven fabric (0.3mm normal 1st base fabric basis weight 110g / m 2 apparent thickness), except that a base fabric the three base cloths overlap, in the same manner as in example 1 And got a soundproof carpet. As for soundproofing, the sound insulation grade (L) was 37 and “◯”, and the winding property was able to be wound without any problem although it was somewhat square. The feeling of walking was evaluated as grade 5 since the carpet was lower than in Example 1. Further, the drying of the adhesive layer was satisfactory without any problem.

<比較例1>
実施例1において、ポリエステルのスパンボンド不織布(通常の1st基布 目付110g/m見かけ厚みが0.3mm)にタフティングした後、2nd基布としてポリエステルのニードルパンチ不織布(目付410g/m見かけ厚みが8mm)を張り合わせた以外は、実施例1と同様にして防音カーペットを作成した。防音性は遮音等級(L)が38で「○」、巻き取り性は問題なく綺麗に巻くことができ、歩行感も良好で4級と評価したが、接着剤層の乾燥において、加工スピードを落とさざるをえず、16分間の乾燥時間となってしまった。
<Comparative Example 1>
In Example 1, a polyester spunbonded nonwoven fabric (ordinary 1st base fabric basis weight 110 g / m 2 apparent thickness 0.3 mm) was tufted, and then a polyester needle punch nonwoven fabric (410 g / m 2 basis weight) was used as a 2nd base fabric. A soundproof carpet was prepared in the same manner as in Example 1 except that the thickness was 8 mm. The sound insulation is rated as “○” with a sound insulation grade (L) of 38, and the winding property can be wound neatly without any problems, and the walking feeling is also good, and it was evaluated as a fourth grade. It had to be dropped, and the drying time was 16 minutes.

<比較例2>
実施例1において、ポリエステルのニードルパンチ不織布(目付410g/m見かけ厚みが8mm)にかえて、目付40g/m見かけ厚みが0.8mmを、ポリエステルのスパンボンド不織布(通常の1st基布 目付110g/m見かけ厚みが0.3mm)に重ねて基布とした以外は、実施例1と同様にして防音カーペットを作成した。防音性は遮音等級(L)が45で「×」、巻き取り性は問題なく綺麗に巻くことができ、歩行感は硬く3級と評価を落とし不合格であったが、接着剤層の乾燥においては、実施例1同様全く問題なく良好であった。
<Comparative example 2>
In Example 1, a polyester spunbond nonwoven fabric (ordinary 1st base fabric basis weight) was used instead of the polyester needle punch nonwoven fabric (410 g / m 2 basis weight, 8 mm apparent weight) and 40 g / m 2 basis thickness 0.8 mm. A soundproof carpet was prepared in the same manner as in Example 1 except that 110 g / m 2 ( apparent thickness was 0.3 mm) was used as a base fabric. The soundproofing grade is 45 with a sound insulation grade (L) of 45, and the winding property can be wound neatly without any problem. The feeling of walking is hard and it was rejected as grade 3, but the adhesive layer was dried. As in Example 1, it was satisfactory without any problem.
