[Field of Application of Industrial Article] The present invention relates to a multi-layer flat yarn, particularly a multi-layer flat yarn that can be widely used as a woven fabric. [Prior Art] Flat yarns in which thermoplastic synthetic resin layers having a melting point lower than that of the drawn flat yarn are provided on both sides of the drawn flat yarn of thermoplastic synthetic resin are already known. For example, Japanese Utility Model Publication No. 53-49902 discloses that a woven fabric is woven using such flat yarns, and the longitudinal and horizontal flat yarns are bonded by thermocompression by heating the outer thermoplastic resin at a temperature higher than the melting point. has been done. The flat yarn used here is generally made by applying adhesive on both sides of the drawn flat yarn.
A method of bonding a low melting point thermoplastic synthetic resin film, or a method of fusing a low melting point thermoplastic synthetic resin on both sides of a thermoplastic synthetic resin layer that will become a stretched flat yarn in a composite die using two extruders. It is produced by a method in which a laminated film is made by extruding it from a composite die, and then stretched and slit. Of these, the latter method is often used. However, the drawn flat yarn produced by either method has a smooth surface of the low melting point thermoplastic synthetic resin formed on the surface and has extremely high frictional resistance. The winding tension of the winder becomes higher than the adjustment function of the winder or the tension becomes uneven due to the contact between the drawn flat yarns and the smooth movement of the drawn flat yarns. Therefore, the appearance of the wound package may become an hourglass shape as shown in Fig. 2 due to the tightness of the winding, or the non-uniformity of the winding tension may cause twill drop as shown in Fig. 3. There was a problem. Therefore, when the drawn flat yarn is taken out from the above-mentioned package to weave cloth or to manufacture various other products, the drawn flat yarn gets caught and the release properties are extremely poor, and the drawn flat yarn is The width will become uneven and productivity will drop 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 drawn flat yarns, making it impossible to weave uniform woven fabrics. is occurring. [Problems to be Solved by the Invention] Therefore, an object of the present invention is to improve the surface properties of a drawn flat yarn to provide a drawn flat yarn with excellent winding properties. moreover,
An object of the present invention is to provide a drawn flat yarn with excellent weaving suitability. [Means for Solving the Problems] The present invention is 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 constituting the outer surface of the drawn flat yarn. It was done. That is, the present invention provides thermoplastic synthetic resin layers having a lower melting point than the stretched tape on both sides of a stretched thermoplastic synthetic resin tape, and also contains an inorganic filler in the thermoplastic synthetic resin layer.
To provide a multilayer flat yarn characterized by having unevenness formed on its surface. 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, for example,
It is formed from high density polyethylene, low density polyethylene, medium density polyethylene, polypropylene, polyvinyl chloride, polystyrene, polyvinyl alcohol, polyacrylonitrile, polyvinylidene chloride, polyamide, polyester, etc. Here, the low melting point thermoplastic synthetic resin layer is formed from a thermoplastic synthetic resin having a melting point 15 to 35°C, preferably 20 to 30°C lower than that of the thermoplastic synthetic resin forming the drawn flat yarn of the core material. It is better. In the present invention, a preferable configuration of the drawn flat yarn is that the core material is high density polyethylene or polypropylene, and the low melting point thermoplastic synthetic resin layer is low density polyethylene or low melting point polypropylene. In the present invention, examples of the inorganic filler contained in the low melting point thermoplastic synthetic resin layer include silicon oxide, calcium carbonate, talc, and kaolin. Among these, silicon oxide and calcium carbonate are preferable, and silicon oxide is particularly preferable, and 0.1 to 4% by weight (hereinafter, %
It is abbreviated as. ), preferably 0.4 to 3%. In addition, especially when using low density polyethylene as a thermoplastic synthetic resin with a low melting point, 0.1
The content is preferably from 1% to 1%, and when low melting point polypropylene is used, the content is preferably from 1.5 to 3%. In addition, as an inorganic filler, the average particle size is 1
-8 μm, preferably 1.5-5 μm. In the present invention, an inorganic filler can also be added to the drawn flat yarn of the core material. In the drawn flat yarn of the present invention, the low melting point thermoplastic synthetic resin layer can be formed on both sides of the drawn flat yarn of the core material by adhesion. 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, extruding it from a composite die to form a laminated tape, and then stretching the tape. This is because the inorganic filler contained in the low melting point thermoplastic synthetic resin layer is easily exposed to the outside of the tape, further improving the winding properties of the flat yarn. Here, the stretching ratio of the core material is preferably 4 to 12 times, preferably 5 to 8 times. In the present invention, the thickness of the drawn flat yarn of the core material and the low melting point thermoplastic synthetic resin layer formed on the outside thereof can be set to any desired thickness. The thickness is preferably 12 to 45 μm, 1 to 5 μm, preferably 16 to 35 μm, and 2 to 4 μm, respectively.
Further, the width of the multilayer flat yarn can be set arbitrarily, but it is preferably 1 to 3 mm. [Effects of the Invention] According to the present invention, a drawn multilayer flat yarn with improved surface properties is provided. Therefore, the multilayer flat yarn of the present invention has excellent winding properties and weaving suitability, so yield and productivity are improved, and woven fabrics and various other products can be efficiently manufactured. The excellent effect of the present invention is that the inorganic filler added to the surface layer of the multilayer flat yarn forms irregularities on the surface. 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. Next, the present invention will be explained by examples, but the present invention is not limited thereto. [Examples] Example 1 A multilayer flat yarn of the present invention shown in FIG. 1 was produced. In the figure, the core material 2 is a stretched flat yarn (stretching ratio 7 times) of high-density polyethylene (density 0.960, melting point 133°C).
is low density polyethylene (density 0.920, melting point 108℃)
The inorganic filler 4 shown in Table 1 was added. Such a multilayer flat yarn was produced by the following method. That is, a core material extruder that extrudes high-density polyethylene and a coating extruder that extrudes low-density polyethylene mixed with 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, slit in a continuous process, stretched 7 times, and further annealed.
100 multilayer flat yarns with a thickness of Table 1 shows the winding performance of the various multilayer flat yarns thus obtained (Example 1) and the conventional multilayer flat yarn without filler (Comparative Example). The cheese was wound using a winding machine manufactured by Torii Iron Works Co., Ltd. at a speed of 122 m/min and an apparent winding tension of 12 g. Also, in the table, the powder blowing phenomenon is
Low molecular weight polymers and additives are deposited and adhered to the forming machine and the yarn itself due to various stresses during film forming, stretching and other processes, which is a factor that inhibits productivity, and was evaluated based on the following criteria. ○...No impact on production △...Slight impact on production ×...Affect on production
