熱圧着することが開示されている。Flat yarns are already known in which thermoplastic synthetic resin layers having a lower melting point than the drawn flat yarn are provided on both sides of the drawn flat yarn of thermoplastic synthetic resin. For example, in Japanese Utility Model Publication No. 53-49902, a woven fabric is woven using such flat yarns, and the outer thermoplastic synthetic resin is heated to a temperature higher than the melting point to bond the vertical and horizontal flat yarns by thermocompression. This is disclosed.

うな綾落ちが発生するという問題があった。The flat yarn used here is generally formed by applying an adhesive to both sides of a drawn flat yarn and then bonding a low-melting-point thermoplastic synthetic resin film, or by a composite method using two extruders. It is manufactured by a method in which low melting point thermoplastic synthetic river resin is fused to both sides of a thermoplastic base Fft resin layer that becomes a stretched flat yarn in a die, extruded from a composite die to form a laminated film, and then stretched and slit. ing. Of these, the latter method is often used. However, by any method! !
The produced drawn flat yarn also has a smooth surface of the thermoplastic synthetic resin with a low melting point formed on the surface, and has extremely high frictional resistance. Due to this contact, the winding tension of the wine goo may become higher than the wine goo's adjustment capacity, or the tension may become uneven, and the smooth movement of the drawn flat yarn is inhibited. Therefore, the appearance of the wound package: Well, due to the tightness of the winding, it becomes an hourglass shape as shown in Figure 2, and unevenness in the winding tension is compounded, resulting in twill drop as shown in Figure 3. There was a problem that occurred.

う問題が生じている。Therefore, when the drawn flat yarn is taken out from the above-mentioned package to weave woven fabrics or to manufacture various other products, the drawn flat yarn gets caught and release properties are extremely poor, and the width of the drawn flat yarn is becomes uneven and productivity drops significantly. Furthermore, even in looms for weaving woven fabrics, the high frictional resistance of the surface of the thermoplastic synthetic resin layer with a low melting point reduces the weaving suitability of the drawn flat yarn, making it impossible to weave uniform woven fabrics. A problem has arisen.

A further object of the present invention is to provide a drawn flat yarn with excellent weaving suitability.

のである。The present invention was made based on the knowledge that the above problems can be effectively solved by incorporating an inorganic filler into the low melting point thermoplastic synthetic resin layer constituting the outer surface of the drawn flat yarn.

脂で形成するのがよい。In the present invention, the drawn flat yarn forming the core material of the drawn flat yarn and the low melting point thermoplastic synthetic resin layer formed on the outside of the drawn flat yarn are both thermoplastic synthetic resins, such as high-density polyethylene, low density polyethylene, medium density polyethylene, polypropylene,
It is formed from polyvinyl chloride, polystyrene, polyvinyl alcohol, polyacrylonitrile, polyvinylidene chloride, polyamide, polyester, etc. here,
The thermoplastic synthetic resin layer with a low melting point has a melting point of 15 to 15% higher than that of the thermoplastic synthetic resin forming the drawn flat yarn of the core material.
It is preferably made of a thermoplastic synthetic resin with a temperature lower than 35°C, preferably 20 to 30°C.

Examples of inorganic fillers that can be used include silicon oxide, calcium carbonate, talc, and kaolin. Among these, silicon oxide and calcium carbonate are preferred, and silicon oxide is particularly preferred, and 0.1 to 4% by weight (hereinafter abbreviated as %), preferably 0. .4-3

尚、本発明では、無機充填剤を芯材の延伸フラットヤー

い。The drawn flat yarn of the present invention can be formed by adhering the low melting point thermoplastic synthetic resin layer on both sides of the drawn flat yarn of the core material. It is preferable to produce a laminated tape by fusing a low melting point thermoplastic synthetic resin (containing an inorganic filler) on both sides of the thermoplastic synthetic resin that becomes the yarn, extruding it from a composite die to form a laminated tape, and then stretching this. .
このようにすると、低融点の熱可塑性合成樹脂層に含有

。ここで、芯材の延伸倍率を４〜１２倍、好ましくは５
〜８倍とするのがよい。In this way, the inorganic filler contained in the low melting point thermoplastic synthetic resin layer is easily exposed to the outside of the tape.
This is because the winding properties of the flat yarn are further improved. Here, the stretching ratio of the core material is 4 to 12 times, preferably 5 times.
It is better to make it ~8 times.

μm, 1-5 μm1 preferably 16-35 μm12-
The thickness is preferably 4 μm. Further, the width of the multilayer flat yarn can be set arbitrarily, but it is preferably 1 to 3 mm.

製造することができる。According to the present invention, a drawn multilayer flat yarn with improved surface properties is provided. Therefore, since the multilayer flat yarn of the present invention has excellent winding properties and suitability for a loom, yield and productivity are improved, and woven fabrics and various other products can be efficiently manufactured.
そして、このような本発明の優れた効果；よ、複層フラ

面に凸凹が形成されることによるものと推定される。It is presumed that such excellent effects of the present invention are due to the formation of irregularities on the surface by the inorganic filler added to the surface layer of the multilayer flat yarn.
従って、本発明によれば複層フラットヤーンを経緯糸と
して織機で網状等に織った後、経緯の交差点を熱融着し
た織布を好適に製造することができる。Therefore, according to the present invention, it is possible to suitably produce a woven fabric in which multilayer flat yarns are woven into a net shape or the like using a loom as warp and warp yarns, and then the intersections of the warp and warp are heat-sealed.
次に本発明を実施例により説明するが、本発明はこれら

つワイングーで巻取った。That is, a core material extruder that extrudes high-density polyethylene and a coating extruder that extrudes low-density polyethylene mixed with a filler are connected to a 200φ circular die, and a low-density polyethylene containing filler 4 is connected. After the polyethylene is introduced into the die, it is branched into two, placed on both sides of the high-density polyethylene flow path, and flows out from the outlet of the die. This is cooled to form a tape with a three-layer structure, which is slit in a continuous process, stretched 7 times, and further annealed so that the core material 2 has a thickness of 16μ and both coating layers 3 and 3 have a thickness of 2μ each. I obtained 100 strands of me flat yarn and wound them one by one using a wine goo.

In addition, the powder blowing phenomenon in the table refers to the agglomeration of low-molecular-weight polymers and additives that accumulate and adhere to the forming machine and yarn itself due to various stresses during the film forming, stretching, and drawing processes, which inhibits productivity. It was evaluated based on the following criteria.

か又はそれ以上の好結果を得た。As can be seen from the experimental results in Table 4, when the flat yarn with added filler is used on a loom, it has a lower rate of loom utilization and noticeable scratches than the yarn with no filler added. It was demonstrated that good results were shown in both cases, and almost the same or better results were obtained in the degree of adhesion of the cloth and the heat seal strength.
