Description
【考案の詳細な説明】 本考案は複合カーペツトに関する。[Detailed explanation of the idea] The present invention relates to composite carpets.
従来より、通気性を有するカーペツトが種々考
案されている。これらのカーペツトには、カーペ
ツト用下地材として断熱性、防音性およびクツシ
ヨン性等に優れた独立気泡構造のオレフイン系合
成樹脂発泡シートを用い、接着剤等によりカーペ
ツト地と接着し複合するものが多い。 Conventionally, various carpets having breathability have been devised. These carpets often use olefin-based synthetic resin foam sheets with a closed-cell structure that have excellent heat insulation, soundproofing, and cushioning properties as the carpet base material, and are bonded to the carpet base using an adhesive or the like. .
しかしながら、これらのオレフイン系合成樹脂
発泡シートは床に施工した後、その上に長時間物
を置くとその部分の凹みが回復せずに跡が残るへ
たり現象が生じたり、温度や湿度の変化による伸
縮が大きく寸法安定性が十分でなかつたり、ふく
れ・しわ現象を生じ易いという難点が有る。 However, after these olefin-based synthetic resin foam sheets are applied to the floor, if something is placed on them for a long time, the dents in the area will not recover and the sheet will sag, leaving marks, and changes in temperature and humidity may occur. There are disadvantages in that the dimensional stability is not sufficient due to the large expansion and contraction caused by the process, and the phenomenon of blistering and wrinkling is likely to occur.
近年、これらの欠点を解消するために、独立気

ートとしてクラフト紙等を積層したカーペツト用
下地材も開発されている。 In recent years, in order to eliminate these drawbacks, carpet base materials have been developed that have a closed-cell structure olefin-based synthetic resin foam sheet with numerous through holes, and kraft paper has also been developed as an anti-expansion sheet for olefin-based synthetic resin foam sheets. Carpet base materials laminated with such materials have also been developed.
しかしながら、前者においては床に対する直下
貼り工法以外の場合ふくれ・しわ現象を生じ易い
し、後者の場合はふくれ・しわ現象を押えること
はできるが、通気性が損われ、へたり現象を起こ
し易いという欠点が解消できない。 However, in the former case, it tends to cause blistering and wrinkling when the method is not applied directly to the floor, and in the latter case, although the blistering and wrinkling phenomenon can be suppressed, air permeability is impaired and it is easy to cause the phenomenon of sagging. Defects cannot be resolved.
また、いずれの構造においても、オレフイン系
合成樹脂発泡シートとカーペツトとの接着の際に
接着剤を使用する場合には溶剤の取扱いが作業上
の問題となり、ホツトメルトフイルムを使用する
場合には通気性を損うばかりでなく、コストの高
さおよびホツトメルトフイルムが柔軟フイルムで
あるための工程の不安定さが問題となる。 In addition, in both structures, handling of solvents becomes a problem when adhesives are used to bond the olefin synthetic resin foam sheet to the carpet, and when hot melt films are used, ventilation is a problem. In addition to impairing properties, there are problems of high cost and instability of the process since hot melt film is a flexible film.
本考案はかかる従来の複合カーペツトの欠点を
解消すべくなされたもので、通気性を有しふく
れ・しわ現象を生じ難い複合カーペツトを提供す
ることを目的とする。 The present invention has been made in order to eliminate the drawbacks of the conventional composite carpet, and an object thereof is to provide a composite carpet that has breathability and is resistant to blistering and wrinkling phenomena.

一体化してなることを特徴としている。 In other words, the composite carpet of the present invention consists of a carpet fabric, a nonwoven fabric sheet in which stretched tape yarns are arranged in two directions, vertically and horizontally, a thermally adhesive system is arranged in at least one direction in the gap, and a large number of nonwoven fabric sheets that penetrate from the front surface to the back surface. It is made by laminating olefin-based synthetic resin foam sheets with a closed cell structure provided with holes, and the carpet fabric and the foam sheet are integrated by thermal adhesion via the thermally adhesive threads of the nonwoven fabric sheet. It is characterized by

と接着性がよくない。 As shown in detail in FIG. 2, the nonwoven fabric sheet 3 is a warp-warp laminated fabric in which stretched tape yarns 6 of high-density polyethylene or polypropylene are arranged in two directions, lengthwise and widthwise, and thermally adhesive in at least one direction of the gap. The threads 7 are arranged. The stretched tape yarns arranged vertically and horizontally are highly stretched, so they have high strength in the vertical and horizontal directions and have low thermal expansion, thereby preventing blistering and wrinkling. The heat-adhesive thread 7 is made of a hot-melt adhesive whose main component is synthetic resin such as ethylene-vinyl acetate copolymer or synthetic rubber, and is formed into a thread shape.
and are bonded together by thermal bonding. and thermoadhesive thread 7
is contained in the nonwoven fabric sheet 3 in an amount of 3 to 30 g/m 2 .
If it contains more than 30g/m 2 , adhesion will improve, but air permeability will be impaired. Also, the adhesiveness is not good, being only less than 3g/m 2 .

る。 The olefin-based synthetic resin foam sheet 5 having a closed cell structure is provided with a large number of through holes 4 penetrating from its front surface to its back surface. In order to provide the through holes 4 in the olefin-based synthetic resin foam sheet 5, a known method such as a needle punch method can be used.
