Description

  The present invention relates to an interlining that is sewn and attached along the upper edge of curtain fabric to suspend a curtain.

  The cloth curtain is suspended from a rail attached to the inside of the upper end of the window and can move along the rail. In this case, a plurality of sliders are attached to the upper end of the curtain fabric with a predetermined interval, and each of these sliders can be loosely fitted on the rail and move. A key is connected to the slider, and the key is locked to the upper edge of the curtain fabric.

  In this way, the curtain fabric is suspended from the rail via the slider, but the interlining is stitched to the upper edge portion of the curtain fabric so that the upper edge portion does not hang down. As shown in FIG. 3, this curtain interlining is a strip-like interlining made of woven relatively thick warps (I) and wefts (B) of about 300 to 400 denier. The strip-shaped interlining is stiffer than the curtain fabric, so that the curtain hanging on the rail can give an elegant appearance.

  By the way, the conventional interlining is a structure in which warp yarns (I) and weft yarns (B) are woven. Since these yarns are relatively thick monofilaments, the crossing portions (c) meshing with each other are not stable. , Produces slip. That is, the slippage causes a breakage and the shape of the interlining itself is deformed. When such an interlining is sewn and incorporated into the curtain fabric, the curtain will be distorted, and if the curtain fabric is thin, the broken state will be visible and the aesthetics of the curtain will be impaired. It will be.

  As shown in FIG. 4, when the warps (A), (A),... Tilt and the textures (D), (D),... As the width of the ground decreases, the curtain length will change partially. Furthermore, the reinforcing function of the interlining is also inferior due to the breakage. Therefore, in order to prevent breakage and stabilize the shape of the interlining, a resin film may be applied, but the cost increases accordingly.

  “Curtain interlining substrate” according to Japanese Patent Application Laid-Open No. 8-299161 is a curtain material that stabilizes the interlining shape without applying a resin film, has flexibility in the length direction of the curtain, and does not cause breakage. Interlining.

Therefore, a multifilament is used as the warp and a composite filament is used as the weft to form a tape. This composite filament is a core-sheath type composite filament in which the sheath material is a resin component having a low melting point and the core material is a resin component having a higher melting point. When this interlining substrate is heat-treated to melt only the low melting point sheath material of the composite filament, the intersection between the warp and the weft is fused and fixed with the melt, thereby preventing the fabric from collapsing.
"Curtain interlining substrate" according to JP-A-8-299161

  In this way, a method of applying a resin coating or heat treatment to prevent the breakage of the curtain interlining is adopted, but an extra process other than weaving is required, which reduces the manufacturing cost of the interlining. Will be higher. The problem to be solved by the present invention is this problem, and provides a curtain interlining that prevents the shape from collapsing due to the design of the woven structure.

  The curtain interlining according to the present invention has a strip shape having a predetermined width, and has a structure woven with warp and weft. Here, the warp and weft yarns may be monofilament yarns of a predetermined thickness or multifilament yarns in which a plurality of thin fibers are bundled. The organization eyes are formed.

  In this way, in the curtain interlining only woven with warp and weft, the shape of the curtain interlining is lost due to breakage as usual. Therefore, in the present invention, the warp yarn is entangled with a small thread. The small swing yarn entangles two adjacent warp yarns in a zigzag shape and restrains the warp yarn and the weft yarn extending in the longitudinal direction and the transverse direction. Here, the small swing yarn is thinner than the warp yarn and the weft yarn, and a multifilament yarn is generally used. And it heat-processes as needed, and a contact is melt | fused by the warp yarn intertwined by fuse | melting a small thread. On the other hand, it is also possible to entangle a small swing yarn in a zigzag manner between adjacent weft yarns instead of warp yarns.

  The curtain interlining of the present invention forms a belt woven by warp and weft, and the warp yarns arranged at a predetermined interval are connected in a zigzag manner with adjacent warp yarns. Therefore, these warp yarns are restrained and positioned with each other by the small swing yarns, so that the shape of the interlining itself is not deformed. In particular, if the woven interlining is heat-treated, the contact point between the small thread and the warp is fused and fixed, and the interlining shape is more stable.

  FIG. 1 is an embodiment showing a curtain interlining according to the present invention, and its appearance has a band shape with a constant width. Therefore, 1 in the figure represents warp, 2 represents weft, and 3 represents a small thread. The warp yarn 1 and the weft yarn 2 are monofilament yarns that do not stretch, and the material is not particularly limited. For example, the warp yarn 1 and the weft yarn 2 made of a material such as polyester can be used. The cross section of the yarn is generally circular, but it may be oval or square.

  One small swing yarn 3 is thinner than the warp yarn 1 or weft yarn 2 and is a highly flexible yarn, for example, a multifilament yarn in which a plurality of very thin fibers are bundled. That is, the small swing yarn 3 is entangled between adjacent warp yarns 1 and 1 in a zigzag manner and restrains both warp yarns 1 and 1 from moving. In order to achieve this, it is preferable that the small thread 3 is thin and highly flexible.

  FIG. 2 is a partially enlarged view of the curtain interlining shown in FIG. In the figure, warp yarns 1a, 1b, 1c... And weft yarns 2, 2... Cross each other to form a woven structure, and small swing yarns 3a, 3b, 3c. , 1c... Are intertwined with the woven structure. Here, for the sake of clarity, the small thread 3a, 3b, 3c,...

  By the way, in the woven structure formed by intersecting the warp yarns 1a, 1b, 1c... And the weft yarns 2, 2,. .. 3a, 3b, 3c,... The small swing yarn 3a is intertwined in a zigzag manner between the two warps 1a and the warps 1b. That is, after winding and locking on the warp 1a, winding and locking on the warp 1b, and then winding and locking again on the warp 1a. This state is repeated and incorporated in a zigzag shape.

  After the small swing yarn 3b is wound around the warp 1b and locked, it is wound around the warp 1c and locked, and is wound around the warp 1b again and locked. This state is repeated and incorporated in a zigzag shape. Similarly, after the small swing yarn 3c is wound around the warp 1c and locked, it is wound around the warp 1d and locked, and then is wound around the warp 1c again and locked. This state is repeated and incorporated in a zigzag shape.

  Here, the small swing yarns 3a, 3b, 3c may be separate independent yarns, or a single continuous yarn may be used. In this way, the small swing yarns 3a, 3b, 3c... Are entangled with the adjacent warp yarns 1a, 1b, 1c. Accordingly, the warp yarns 1a, 1b, 1c... Are restrained by these small swing yarns 3a, 3b, 3c.

  Accordingly, the interlining extending in a band shape with a constant width does not change its shape due to the collapse of the textures 4, 4... And becomes a stable interlining. And since the small thread 3a, 3b, 3c ... is thin, the rigidity of the interlining does not become higher than necessary. As described above, the small yarns 3a, 3b, 3c,... Are tangled in the warps 1a, 1b, 1c,. Then, the small thread 3a, 3b, 3c is melted and fused with the warps 1a, 1b, 1c.

  The heat treatment temperature is kept to the minimum necessary, and the small knitting yarns 3a, 3b, 3c,. If the warp yarns 1a, 1b, 1c,... Are fused at the intersections, the warp yarns 1a, 1b, 1c,... Are completely fixed, and the interlining is not broken or deformed.

  Incidentally, in the embodiment, the small knitting yarns 3a, 3b, 3c,... Are tangled with the warps 1a, 1b, 1c,. It is also possible to match. In this case, the weft yarns 2, 2... Arranged at equal intervals are restrained by the small swing yarns 3, 3,. If the interlining thus constructed is sewn along the upper edge of the curtain fabric, the curtain will not be partially distorted and an elegant appearance can be obtained.
