加熱加圧する。 The above is a case where a resin that is fluid at room temperature, such as emulsion latex or paste resin, is used as the adhesive, but the adhesive is not limited to this, and hot melt type adhesives in the form of film or powder can also be used. In these latter cases, it is applied and then heated and pressed so as to form a film 16 integral with the fluff 12.

本発明に係るタフテツド布帛１８は、この様に

制限し或は縮減するものではない。 The tufted fabric 18 according to the present invention is finished by forming the film 16 in this way, but if necessary, the tufted fabric 18 may be further backed with an adhesive, a secondary base fabric, etc. as described below. The effects of this are also exhibited in such backing processing, and such backing processing does not limit or reduce the technical scope of the present invention in any way.

〔Effect of the invention〕

本発明によると、接着剤１３と毛羽１２とが一
体になつた厚み１mm以下、目付100ｇ／m²以下の
不織布状の平らな皮膜１６によつて、タフテツド
布帛１８は恰も極薄不織布を裏打した如くバツク
ステツチ１１の凹凸が覆われ綺麗に仕上げられ
る。 According to the present invention, the tufted fabric 18 is lined with an ultra-thin non-woven fabric by the non-woven flat film 16 which is made up of adhesive 13 and fluff 12 and has a thickness of 1 mm or less and a basis weight of 100 g/m ² or less. As a result, the unevenness of the backstitch 11 is covered and finished neatly.

この様に、バツクステツチ１１は先願技術と同
様に不織布状の皮膜１６で覆われるが、その皮膜
１６は、先願技術と異なり不織布を裏打したもの
ではなく、ただ接着剤１３の付着したバツクステ
ツチ１１の表面毛羽１２を撫でることによつて形
成されるものであるから、極薄不織布を裏打する
先願技術に比して簡便に形成することが出来る。 In this way, the back stitch 11 is covered with a non-woven film 16 as in the prior art, but unlike the prior art, the film 16 is not lined with a non-woven fabric, but simply covers the back stitch 11 to which the adhesive 13 is attached. Since it is formed by stroking the surface fuzz 12 of the paper, it can be formed more easily than the prior art which uses ultra-thin non-woven fabric as a backing.

又、皮膜１６を形成する接着剤１３は、先願技
術のそれとは異なり、基布１４に付着せず、又、
バツクステツチ１１のパイル糸の内部に浸透して
おらず、且つ、ステツチ列の隣り合うバツクステ
ツチ１１と１１′、１１′と１１″……の相互間の
谷溝１５に侵入してそこを充填するものではない
ので、バツクステツチ１１が基布１４は接着剤１
３に固められず、それらの繊維糸条が自由に滑動
し得る状態にあるから極めて可撓性に富むタフテ
ツド布帛１８が得られる。 Further, the adhesive 13 forming the film 16 does not adhere to the base fabric 14, unlike that of the prior art, and
It does not penetrate into the inside of the pile yarn of the back stitch 11, but penetrates into the grooves 15 between adjacent back stitches 11 and 11', 11' and 11'', etc. in the stitch row to fill them. Since back stitch 11 is not
The tufted fabric 18 is extremely flexible because the fiber threads are free to slide without being hardened.

この様に、バツクステツチ１１や基布１４が接
着剤１３に接着されていないが、裏面の皮膜１６
を形成する毛羽１２の繊維は表面のパイル２６か
ら続いており、それらがステツチ列の隣り合うバ
ツクステツチ１１と１１′、１１′と１１″……の
間で交絡して接着されているから、パイル２６
は、恰も毛根を絡ませた芝生の様に引き抜き難
く、抜糸強度に優れたものとなる。 In this way, the back stitch 11 and the base fabric 14 are not bonded to the adhesive 13, but the film 16 on the back side
The fibers of the fluff 12 that form the pile continue from the pile 26 on the surface, and are intertwined and bonded between the adjacent back stitches 11 and 11', 11' and 11'', etc. in the stitch row, so the pile 26
It is difficult to pull out like grass with entangled hair roots, and has excellent suture removal strength.

一方、基布１４は、接着剤１３によつてパイル
２６に接着されておらず、タフテイング直後と同
じ様にパイル２６を軽く係止しているだけ基布１
４とパイル２６とは引き離し可能になつているか
ら、基布１４を引つ張つてパイル面から剥ぎ取る
ことが出来る。 On the other hand, the base fabric 14 is not adhered to the pile 26 by the adhesive 13, and the base fabric 14 is only lightly anchored to the pile 26 in the same way as immediately after tufting.
4 and the pile 26 can be separated, so the base fabric 14 can be pulled and peeled off from the pile surface.

このため第３図に図示する如く、本発明に係る
タフテツド布帛１８，１８′は、それを２枚裏面
皮膜同志１６，１６′を貼り合わせ、その後、そ
れらの基布１４，１４′を剥ぎ取ることにより、
表裏のタフテツド布帛１８，１８′の皮膜１６，
１６′が一体になつて中間層２７を形成し、そこ
からパイル２６，２６′が表裏に突き出た基布１
４，１４′のない極めて可撓な両パイル布帛２８
を得ることが出来る。 For this reason, as shown in FIG. 3, the tufted fabrics 18, 18' according to the present invention are obtained by bonding two back-coated fabrics 16, 16' together, and then peeling off their base fabrics 14, 14'. By this,
The front and back tufted fabrics 18, 18' coating 16,
16' are integrated to form an intermediate layer 27, from which piles 26, 26' protrude from the front and back sides of the base fabric 1.
Extremely flexible double pile fabric 28 without 4, 14'
can be obtained.

そして、それらを貼り合わせる場合、それらの
タフテツド布帛１８，１８′の裏面に接着剤を塗
布しても不織布状の皮膜１６，１６′に阻まれ、
従つて、その際塗布する接着剤が内部浸透して基

がない。 When bonding them together, even if adhesive is applied to the back surfaces of the tufted fabrics 18, 18', it will be blocked by the non-woven fabric films 16, 16'.
Therefore, the adhesive applied at that time does not penetrate into the interior and bond and fix the base fabric 14 and the pile 26.

同様に、本発明により得られたタフテツド布帛
１８の裏面に更に他の裏打加工を施すとしても、

地１９の持つ柔らかい風合を損なわず、これによ
つてかかる二次的裏打加工が本発明の技術的範囲
を何等制限或は縮減するものではないことが理解
されよう。 Similarly, even if another backing process is applied to the back side of the tufted fabric 18 obtained by the present invention,
The adhesive applied at this time does not penetrate into the backstitch and adhere to the base fabric or panel, making them rough and hard. Therefore, the soft texture of the tufted fabric 19 is not impaired and the It will therefore be understood that such secondary backing does not in any way limit or diminish the scope of the invention.

この様に本発明のタフテツド布帛は可撓性に富

の皮膜１６を厚み１mm以下で目付100ｇ／m²以下、
好ましくは厚み0.1〜0.5mm程度で目付10〜50ｇ／
m²程度にすることが要求される。 As described above, the tufted fabric of the present invention is characterized by its high flexibility and soft texture, and the film 16 must not be thick and coarse due to excessive amounts of fluff or adhesive. For this purpose, the average weight of the fluff 12 should be 30% by weight or less, preferably about 5 to 10% by weight, of the pile yarn of the backstitch 11, and the coating 16 should have a thickness of 1 mm or less and a basis weight of 100 g/m ² or less.
Preferably, the thickness is about 0.1 to 0.5 mm and the basis weight is 10 to 50 g/
It is required to be approximately ² m2.

他方、毛羽１２が余り少なかつたり短すぎる場

しなければならない。 On the other hand, if the fluff 12 is too small or too short, the adhesive 13 will penetrate into the fabric and make the back stitches and base fabric rough and hard, and the film 16 covering the back stitches will not be formed, so the average length of the fluff 12 will be too short. Apparent thickness d of pile yarn and tuft gauge g
The average weight must be at least twice that of 5g/ ^m2 .

5 is not filled, and the grooves 15 are filled with the coating 16 and the base fabric 1.
4. Therefore, when the tufted fabric 18 of the present invention is used in a place that is constantly bent, such as a chair cover, the air gap 17 sucks air every time it is bent. The tufted fabric 18 of the present invention has a pumping effect and does not give a damp feeling, and when the tufted fabric 18 of the present invention is used as a surface material for a simple rug or electric carpet, the voids 17 exhibit an excellent moisturizing and heat insulating effect. do.

するところ多大である。 As is clear, the tufted fabric according to the present invention can be used for simple rugs, electric carpet outer materials, chair covers, etc. that require flexibility for folding and storage.
Or, it has the advantages of double-sided pile fabric, the back side is as flat and beautiful as if it were lined with a secondary base fabric, and it feels good to the touch, and yet, as in the prior art, it can be used with ultra-thin non-woven fabric and special equipment to spread it. There are many industrial advantages of the present invention, such as the fact that the backstitch can be obtained simply by lightly scratching the backstitch prior to the usual backing process.
