[0008]

BEST MODE FOR CARRYING OUT THE INVENTION A first embodiment of a curtain core material according to the present invention will be described with reference to FIG. 1. A woven fabric T composed of warp yarns 1 and weft yarns 5 is heat-processed, and the weft yarns 5 are core yarns. 8 is composed of a core-sheath type composite yarn 7 having a melted layer 9 on the outer periphery thereof, and a monofilament yarn 6 woven together with the composite yarn 7, and the melted layer 9 of the core-sheath type composite yarn 7 is melted by heating and melted. 19
Therefore, the core yarn 8 and the monofilament yarn 6 are fixed, and the warp yarn 1 is also fixed. A multifilament made of polyester fiber was used as the core yarn 8 of the core-sheath composite yarn 7, and a polyester having a lower melting point (130 to 210 ° C.) than the core yarn 8 or the monofilament yarn 6 or the warp yarn 1 was used as the melting layer 9. .

The difference between the second embodiment of the curtain core material according to the present invention and the first embodiment will be described. As shown in FIG. 2, the woven fabric T has a tape width with an appropriate width H, and the warp yarns 1 are woven fabrics. The core yarns 8a and monofilament yarns 6a located at the outermost ends on one side and the core yarns 8b located at the outermost ends on the other side are folded back by passing over the outermost weft yarns 5a, 5b in the width direction.
And the monofilament yarn 6b are folded back and woven in a meandering state, and the end portion core yarn 8a and the endmost monofilament yarn 6a, the endmost core yarn 8b are woven by the melting portion 19 of the melting layer 9.

The bell-belt brand name "Bell Couple" using a low-melting point polyester polymer was used for the core yarn, but the bell-belt brand name "Bell Couple" using the low-melting point polyester polymer for the core yarn 8 and the polyester layer for the melt layer 9 was used. It is also possible to use "Bell Couple NP", a brand name of Kanebo, which uses a polyester polymer for the core yarn 8 and a polyamide polymer for the melt layer 9. The melting point temperature difference between the molten layer 9 and the other yarns (warp yarn 1, monofilament 6, core yarn 8) is
In order to easily melt only the molten layer 9, the temperature is set to 30 ° C. or higher.

Since the curtain core material according to the present invention has the above-mentioned structure, it has the following effects. The curtain core material according to claim 1 uses a monofilament along the core-sheath type composite fiber as the weft thread, and melts the molten layer of the core-sheath type composite fiber by heat treatment to fix the monofilament and the core thread together. Since the warp yarns are also fixed, the fabric structure is very stable, and the collapse of the fabric can be prevented while maintaining the flexibility in the longitudinal direction. Even if a monofilament is used together with the core yarn, the bending in the longitudinal direction is still soft, so sewing is easy and the pleats when the tack is removed are beautiful. Since there is no warp thread cut at the end in the width direction, the warp thread cut does not hurt fingers or lock onto the curtain cloth when it is attached to the curtain cloth, and as a result, the installation on the curtain cloth is extremely easy and easy. Become. Moreover, after the installation, a curtain surface that looks good is formed.

According to the curtain core material of claim 2, since the weft yarn is formed of three or more yarns consisting of the monofilament and the core yarn, it is more flexible in the longitudinal direction than the conventional fabric using a plurality of multifilament yarns. Will be secured.
