カーペットの二次基布用不織布に関するものである。Detailed Description of the Invention (Field of Industrial Application) The present invention improves the deep drawability and shape retention of tufted carpet materials and needle punch carpet materials used for car mats, as well as good adhesion to felt. The present invention relates to a nonwoven fabric for use as a secondary base fabric for carpets.

が要求される。(Prior art) Conventionally, when manufacturing nonwoven fabrics for secondary carpet base fabrics, methods for fixing fibers to each other include fixing them with an emulsion binder, mixing fibers with a hot melt binder, and further fixing them. Also, a method of entangling and fixing with needle punching is commonly used. The thus obtained nonwoven fabric for the secondary base fabric of the carpet is laminated in the backing process, and in cases where molding is required, such as car mat molding, it is press molded, but in this process stable moldability is achieved. Shape retention is required, and other properties such as good adhesion to felt are also required.

ため二次基布用不織布の使用は不可欠になってくる。In general car mat molding, only a portion of the backing-treated carpet is melted and softened in a heating furnace, and then molded using a press molding machine. Molding methods are being switched from separate partial molding of the front and rear parts to integral molding, and molds have also come to have complex uneven shapes. Moreover, the molded product completed with this method is a floor.
It is necessary to fit it tightly. When tufted carpets with backing are deep drawn, they tend to tear during molding, and needle-punched carpets alone cannot maintain their shape and have poor fit, so nonwoven fabrics for secondary base fabrics are used. use becomes essential.

ていた。Carpets with a secondary base fabric are generally produced by extruding a backing agent onto the back side of the carpet using the Ruder method, and at the same time sending out a nonwoven fabric for the secondary base fabric thereon and pressing and bonding with a cooling row. However, in the molding process, it is necessary to partially bond the felt and the carpet with the secondary base fabric. For this reason, a method has been adopted in which the adhesive strength between the felt and the carpet with a secondary base fabric is increased through an adhesive application process.

却ローラで押さえた時に。(Problems to be Solved by the Invention) As described above, if the nonwoven fabric for the secondary base fabric is laminated, deep drawing is possible and the shape retention is improved, but a problem remains in the adhesive strength of the felt. Conventionally, when pressed with a cooling roller during the process of making a carpet with a secondary base fabric.

う問題があった。Although it was possible to bond to felt, the adhesive strength was poor because only a portion of the backing agent oozed out from the gap in the nonwoven fabric for the secondary base fabric to act as an adhesive. For this reason, the process of applying adhesive was added, which caused the problem of high processing costs.
本発明の目的は成型工程においてフェルトと二次基布付
きカーペットとの接着剤塗布工程を必要とせず、しかも
フェルトとの強い接着力を有する二次基布用不織布を提
供することにある。An object of the present invention is to provide a nonwoven fabric for a secondary base fabric that does not require an adhesive application process between felt and a carpet with a secondary base fabric in the molding process, and has strong adhesive strength with felt.
（問題点を解決するための手段）
すなわら本発明は、ポリエチレンテレフタレートを芯成

熱接着繊維からなることを特徴とするカーペットの二次
基布用不織布を要旨とする。(Means for Solving the Problems) In other words, the present invention provides a nonwoven fabric made of a core-sheath composite fiber having polyethylene terephthalate as a core component and polyethylene as a sheath component, in which the weight ratio of polyethylene to polyethylene terephthalate is 10 to 10. The object of the present invention is to provide a nonwoven fabric for a secondary base fabric of a carpet, characterized in that the nonwoven fabric is made of thermally bonded fibers having a carbon fiber content of 90% by weight and a single filament fineness of the composite fibers of 20 denier or less.
以下本発明について詳述する。The present invention will be explained in detail below.
本発明の複合繊維の鞘成分として用いられるポリエチレ

密度ポリエチレンのいずれであってもよい。またこれら
の混合物であってもよく、なかでも炭素数４〜８のαオ
レフィンとエチレンを共重合して得られる直鎖状低密度
ポリエチレンは可紡性がよく、風合も接着強力も良好な
二次基布不織布が得られる。The polyethylene used as the sheath component of the composite fiber of the present invention may be any of conventionally commercially available low-density polyethylene, medium-density polyethylene, high-density polyethylene, and other linear low-density polyethylene. It may also be a mixture of these; among them, linear low-density polyethylene obtained by copolymerizing ethylene with an α-olefin having 4 to 8 carbon atoms has good spinnability and good texture and adhesive strength. A secondary base nonwoven fabric is obtained.
本発明で用いられるポリエチレンテレフタレートは固有
粘度が０．５０〜１．２０の範囲のものが好ましい。固
有粘度が０．５０以下では強度の高い繊維が得られにく
く満足できる不織布にならないし。The polyethylene terephthalate used in the present invention preferably has an intrinsic viscosity in the range of 0.50 to 1.20. If the intrinsic viscosity is less than 0.50, it will be difficult to obtain fibers with high strength and a satisfactory nonwoven fabric will not be obtained.
また固有粘度が１．２０を超えると可紡性が良くない。Moreover, if the intrinsic viscosity exceeds 1.20, spinnability is poor.
繊維の形態はポリエチレンがポリエチレンテレフタレー

チレンが１０〜９０重景％に対し、ポリエチレンテレフ
タレートが９０〜１０重量％であることが必要である。The fibers have a cross-sectional shape in which polyethylene is coated with polyethylene terephthalate, and the composition ratio thereof is 10 to 90% by weight of polyethylene and 90 to 10% by weight of polyethylene terephthalate.
ポリエチレンが１０重量％未画の場合は繊維の強度は高
（でもフェルトとの接着力が弱くなったり、被覆状態が
悪くなったりするので好ましい二次基布用不織布は得ら
れない。When 10% by weight of polyethylene is unpainted, the strength of the fibers is high (but the adhesion to the felt is weak and the covering condition is poor, so a desirable nonwoven fabric for the secondary base fabric cannot be obtained).
逆にポリエチレンが９０重量％を超えるとフェルトとの
接着力は強くなるが、繊維の強度が低くなり、二次基布
用不織布の特徴である深絞りが難しく、成型性と保型性
が悪くなって好ましくない。On the other hand, if polyethylene exceeds 90% by weight, the adhesive force with felt will be strong, but the strength of the fiber will be low, making it difficult to perform deep drawing, which is a characteristic of nonwoven fabrics for secondary base fabrics, and poor moldability and shape retention. I don't like it.
本発明において繊維の太さは単糸繊度が２０デニール以
下にする必要がある。単糸繊度が２０デニールを超える
と不織布を構成する単糸の数が減少して目の粗い不織布
となり、成型性と保型性がわるくなる。In the present invention, the thickness of the fiber needs to be such that the single yarn fineness is 20 denier or less. When the single yarn fineness exceeds 20 denier, the number of single yarns constituting the nonwoven fabric decreases, resulting in a coarse nonwoven fabric with poor moldability and shape retention.

も必要としない。The spinning temperature is 180 to 270°C for the polyethylene side and 280 to 310°C for the polyethylene terephthalate side. The heat-adhesive fiber of the present invention is produced by melt-spinning continuous filaments, which are processed by air sucker or take-up roller.
It can be obtained by pulling at a speed of 500 m/min or more, and it is possible to pull at a high speed of several thousand liters per minute. Surprisingly, if a linear low-density polyethylene with favorable melting behavior is selected, a Godet roller or a Nelson roller is not necessarily required.

It shows a state where it is sent out at a constant speed downward in the direction of arrow A. The molten backing agent 2 exits the extruder and is applied to the back surface of the carpet 1, that is, the side opposite to the pile surface.
The carpet is fed out at the same speed as the carpet 1 and bonded together covering the backing agent. The etching rollers (embossing rollers) 4a and 4b have the role of nip rollers and a cooling effect, and the carpet with the secondary base fabric bonded between the etching rollers is inserted and the backing agent is solidified. One side of a nonwoven fabric for a secondary base fabric of a carpet made of heat-adhesive fibers is melt-bonded and then wound onto a first winding roller to obtain a carpet 5 with a secondary base fabric.
