Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、カーペット、マット、タイルカーペット、人
工芝生等の屋内外に使用する敷物類に関するものであ
る。TECHNICAL FIELD The present invention relates to rugs used indoors and outdoors, such as carpets, mats, tile carpets and artificial lawns.
パイル布帛、ニードルパンチ布帛等の繊維製表面材の裏
面にポリ塩化ビニル、ポリオレフイン、ビチューメン等
の熱可塑性樹脂組成物によって形成される厚み２mm以上
の裏打層を積層して寸法安定性を付与し可撓で床面等に
フイット（密着）する様に仕上げたカーペットや人工芝
生等は、１m2程度又はそれ以下の小片に裁断しマットや
タイルカーペット等として使用されている。Dimensional stability can be provided by laminating a backing layer with a thickness of 2 mm or more formed of a thermoplastic resin composition such as polyvinyl chloride, polyolefin, bitumen, etc. on the back surface of a fiber surface material such as pile cloth or needle punch cloth. Carpets and artificial lawns, etc. that have been finished so that they fit to the floor surface etc. by bending, are cut into small pieces of about 1 m 2 or less and used as mats or tile carpets.
それら厚手の裏打層に積層した敷物類は裏打層が熱可塑

上がって足が引っかり易くなるという不都合を生じ、こ
れを防ぐために裏打層内部に伸縮性のないガラス繊維布
帛を介在させるという方法がとられる。In the rugs laminated on those thick backing layers, the backing layer is formed by the thermoplastic resin composition, so that the backing layer is compressed by a slight stepping pressure during use, and is easily stretched in the longitudinal direction by that amount. As a result, the peripheral edge of the rug rises upward and the foot is easily caught. To prevent this, a method of interposing a non-stretchable glass fiber cloth inside the backing layer is adopted.

しみを生じ、或は、その浮き上がった周縁から裏面と床
面の間に塵埃が入り込んで次第にタイルカーペットがず
れ動き易くなる。In rugs in which a thick backing layer formed of a thermoplastic resin composition is laminated, those with a glass fiber cloth interposed in the backing layer have good dimensional stability and no curling of the peripheral edge is observed during use, A pile fabric or needle punched fabric that is a surface material is thickly coated with a thermoplastic resin composition and laminated with a backing layer to finish, even if a glass fiber fabric is inserted during the coating. , When cutting this to make a tile carpet or mat, it tends to warp slightly to the peripheral edge that is the cutting edge, and when such tile carpet is laid with the peripheral edges butted, the peripheral edge is slightly above the floor surface. And the unpleasant squeak occurs during walking, or dust enters between the raised peripheral edge between the back surface and the floor surface, and the tile carpet gradually shifts and becomes easy to move.
これを解消するには裏打層を重厚にし、裏打層の自重に
よって周縁が下向きに撓む様にすればよいのであるが、
それではコスト高になり裏打層を積層する実用上の意味
がなくなってしまう。又、熱可塑性樹脂組成物に可塑剤
を多量に配合して裏打層を一層可撓にするという方法も
あるが、それでは却って使用による周縁の反り上がりひ
どくなり、又、敷物類が可燃性になる等不利不便は免れ
ない。In order to eliminate this, the backing layer should be made thick, and the peripheral edge should bend downward due to the weight of the backing layer.
Then, the cost becomes high and the practical meaning of laminating the backing layer is lost. There is also a method in which a thermoplastic resin composition is mixed with a large amount of a plasticizer to make the backing layer more flexible, but on the contrary, the peripheral edge warps due to use, and the rug becomes flammable. There are some disadvantages and disadvantages.
そこで本発明は、裏打層を必要以上に重厚にせず、周縁
が稍々裏側に向けて反り返り加減の敷物類を経済的に得
ることを主たる目的とする。Therefore, it is a primary object of the present invention to economically obtain a rug in which the backing layer is not excessively heavy and the peripheral edge thereof is warped toward the back side.

Rug 13 such as artificial grass is laminated with a backing layer 12 formed of a thermoplastic resin composition such as polyvinyl chloride, attack polypropylene, bitumen, etc. on the back surface of a fiber surface material 11 such as a pile cloth or a needle punch cloth. The laminated structure of the backing layer 12 has a coarse gap inside the backing layer and exhibits heat shrinkability at a temperature of 170 ° C. or less.
4 has a backing layer 12 and a fabric 14 in a relative relationship with the fabric 1
4 is present inside the backing layer 12.

て形成されるタイルカーペット13をつくった。A thermoplastic resin composition 18 having the following composition on the releasable belt 16
Is applied and laminated with a doctor blade 19 to a thickness of 1 mm,
Next, a coarse woven fabric of polypropylene yarn with a gap of about 0.05 cm 2 between the warp and weft 14 (Basis weight 110 g / m 2 , 150 ° C × 10
Heat shrinkage rate per minute: Vertical 45%, Horizontal: 55%) and glass fiber yarn woven fabric 15 (weight of 45 g / m 2 ), polypropylene yarn woven fabric 14 applied first On top of it, lay a woven cloth of glass fiber yarn 15 on it, and apply them 14
.The above thermoplastic resin composition 18 'is applied and laminated again on the 15 by the doctor blade 21 to a thickness of 1.5 mm, and the applied layer 2
2 is overlaid with a tufted carpet (raw fabric) not backed with a secondary base cloth, and then about 10 in a heating zone 23 at 170 ° C.
Thermoplastic resin composition 18 ・ 18 'is solidified by passing through for 50 minutes
Tile carpet 13 formed by backing layer 12 and tufted carpet 11 was cut into corners.

反り上がった。When this tile carpet 13 is laid on the floor surface 24, the backing layer
The entire surface of No. 12 was in close contact with the floor surface and no warp was seen at the peripheral edge. And when this is turned over and placed on the floor 24,
As shown in Fig. 2, the peripheral edge was warped upward from the center by about 2.5 mm.

れるタイルカーペット13′をつくった。 [Comparative Example] The thermoplastic resin composition 18 used in the above-described examples was applied and laminated on the releasable belt 16 with a doctor blade 19 to a thickness of 1 mm, and the applied layer 20 was coated with a glass fiber yarn. Woven cloth 15
(Basis weight: 45 g / m 2 ) and the glass fiber yarn application 15 is overlaid thereon, and the above thermoplastic resin composition is overlaid thereon.
18 'is again coated and laminated with a doctor blade 21 to a thickness of 1.5 mm, and the coated layer 22 is overlaid with a tufted carpet original fabric 11 and then passed through a heating zone 23 at 170 ° C. for about 10 minutes to form a thermoplastic resin composition 18 * 18 'was solidified and cut into 50 cm square to make a tile carpet 13' formed by the backing layer 12 and the tufted carpet 11.
このタイルカーペット13′を床面24に置敷きすると第３
図に示すように周縁が中央部より約1.5mm表側へと反り
上がった。When this tile carpet 13 'is laid on the floor 24, the third
As shown in the figure, the peripheral edge was warped upward from the center by about 1.5 mm.
本発明に係る敷物類13にあって裏打層12には熱収縮性布

熱により熱収縮が促されるが、その熱収縮応力は裏打層
12の主材たる高粘度の熱可塑性樹脂組成物18・18′によ
って抑えられ裏打層内に潜在化する恰好になる。In the rugs 13 according to the present invention, the backing layer 12 has a heat-shrinkable cloth 14 interposed. The cloth 14 is accelerated in heat shrinkage by heating in the process of forming the backing layer 12, but the heat shrinkage stress is caused by the backing layer.
It is suppressed by the high-viscosity thermoplastic resin composition 18 · 18 ′, which is the main component of 12, and becomes latent in the backing layer.
この結果、得られる敷物類13は、この潜在化した収縮応
力により絶えず裏側に反り返る傾向を示し、従つて表側
に弯曲せず、使用中にも表側への反り上がりが止められ
る。As a result, the rugs 13 obtained tend to constantly warp to the back side due to this latent shrinkage stress, and therefore do not bend to the front side, and the warp to the front side is stopped even during use.
特に、ガラス繊維糸条布帛15と共に熱収縮性布帛14を介
在させたものにあっては、使用中における裏側への反り
返り傾向も適度に抑えられ、仕上がり直後の裏側に稍々
弯曲した状態が維持され、寸法安定性がよく、裏打層12
が熱可塑性樹脂組成物18・18′に成り可撓性を有するの
で床面24に置敷きすると自重によって中央部も床面に密
着し周縁での反り上がりがなく、これを0.25〜1.00m2程
度に裁断するとき使用中に周縁が表側に反り返らないマ
ットやタイルカーペット13が得られる。In particular, in the case where the heat-shrinkable fabric 14 is interposed together with the glass fiber yarn fabric 15, the tendency to warp to the back side during use can be appropriately suppressed, and the back side immediately after the finish can be maintained in a slightly curved state. And has good dimensional stability, backing layer 12
Since it is a thermoplastic resin composition 18 ・ 18 'and has flexibility, when it is laid on the floor surface 24, the central part also adheres to the floor surface by its own weight and there is no warp at the peripheral edge, and this is 0.25 to 1.00 m 2. A mat or tile carpet (13) whose peripheral edge does not warp to the front side during use when cut to an extent is obtained.

は頗る高い。Therefore, a conventional mat used in a place that is frequently stepped on, such as an entrance mat or an automobile mat, requires an edging material to be attached to prevent the warp of the peripheral edge, but according to the present invention, this is unnecessary. The warp to the front side can be effectively stopped without thickening the backing layer 12, and thus the rug 13 such as a mat or tile carpet which is thin and light and has excellent shape stability can be economically obtained, and thus the present invention can be practically used. The sex is extremely high.
