JP6663650B2 - Curtain interlining and curtain fabric - Google Patents

Description

  The present invention relates to a curtain interlining in which pleats are easily formed and a curtain fabric in which pleats are formed.

  The pleated curtain is pleated if the fabric woven by various methods such as plain weave, jacquard weave, and lace fabric is sandwiched between zigzag patterns after weaving, and then put in a kettle and steam heated. Processing is completed. That is, the pleat shape is memorized, and the elegance of the pleat curtain can be maintained without breaking forever. Of course, it is also possible to perform pleating by pressing in a heated state other than heat treatment with steam.

There are many known literature on pleated curtains. For example, “Curtains and Tassels” disclosed in Japanese Patent Application Laid-Open No. 2005-52241 is a curtain in which curtain fabrics and tassel fabrics can be effectively used, sewing is easy, and a decorative effect is high.
In addition, the “pleat-formed fabric and its manufacturing method” according to JP-A-2013-19080 have an optimal rigidity for the hand pleating process, and the hand pleating process can be performed using one sheet of paper. The present invention relates to a laminated coarse cloth on which pleats can be formed easily and which have excellent form retention, and a method for producing the same.
A sheet-like heat-fusible synthetic resin is inserted between the first coarse cloth and the second coarse cloth, and heated and pressed to form a laminated coarse cloth. Next, pleats are provided by bending the laminated coarse cloth together with one sheet of paper.

  However, the pleats formed on the curtain are not permanent, and if the curtain is suspended for a long period of time, the pleats often lose their shape. Then, in order to process the pleats, it is necessary to insert them in a paper pattern, put them in a kettle, and heat them with steam, which increases the number of pleating processes. Of course, pleating requires a considerable cost, such as the need for a heating pot.

  In the case of “the curtain and the curtain or the pleated screen device using the curtain” according to JP 2010-196423 A, the front and back fabrics each having the same number of shape-stored pleats are used as the curtains. Each of the valley folds is superposed on each other, and is bonded to each other at the superimposed portion. The folds of the pleats of the front fabric and the back fabric are bent in the same direction, and the fabric width of the mountain fold of the front fabric is set to be larger than the fabric width of the mountain fold of the back fabric. Since the space is formed between the mountain-folded portion of the front fabric and the mountain-folded portion of the back fabric, the back fabric has a function of retaining the pleated pitch of the front fabric.

  By the way, the curtain according to JP-A-2010-196423 has a front fabric and a back fabric, and each fabric has to be pleated. Two types are required, and the number of processing steps is further increased. In addition, the problem that the processed pleats lose their shape over a long period of time similarly occurs.

"Curtain and tassel" according to JP-A-2005-52241 Japanese Patent Application Laid-Open No. 2013-19080 “Pleated Fabric and Method for Producing the Fabric” “Curtain body and curtain or pleated screen device using the same” according to JP 2010-196423 A

  As described above, the conventional pleated curtain has the above-described problems. The problem to be solved by the present invention is this problem. The pleats can be easily formed at a low cost and can be manufactured at low cost, and the pleats do not collapse. I will provide a.

In the curtain fabric according to the present invention, pleats are formed by sewing the interlining to at least one of the upper end portion and the lower end portion and folding the curtain fabric. That is, as in the related art, a predetermined pleated shape is formed by simply folding the zigzag pattern paper without inserting it into a kettle and heating it with steam.
The interlining is generally made of polyester-based or nylon-based fibers and has a band shape with a constant width.

By the way, in the present invention, a shape holding material is combined with the interlining, and for this purpose, the interlining is folded together with the curtain fabric to be held in a folded pleated shape.
Although the specific material of the shape maintaining material is not limited, for example, “Techno-Rot” (manufactured by Mitsui Chemicals) using “shape maintaining material” according to Japanese Patent No. 3810698 can be used, or shape memory can be used. It is also possible to use a member made of an alloy. The shape holding material forms the interlining as a thin band or string, but the shape holding material extends in the longitudinal direction of the interlining. Here, the band-shaped or string-shaped shape holding material is woven and knitted together with the yarn constituting the interlining, but sometimes it is also possible to adhere to the surface of the interlining.

The interlining according to the present invention has a shape retaining material incorporated in a part thereof and extends in the longitudinal direction, and the interlining can be sewn to the upper end or the lower end of the curtain fabric. If the curtain fabric is folded in a state where the interlining is sewn, the interlining is held in a folded state by the shape holding material.
Therefore, it is not necessary to sandwich the pattern in a zigzag pattern as in the related art, put it in a pot and heat it with steam, and a predetermined pleating process can be easily formed. Needless to say, the pattern paper and the kettle become unnecessary, and no steam is used, so that the manufacturing cost of the pleated curtain is reduced. Then, the formed pleats do not collapse even after a period, and become a curtain having beautiful pleats forever.

The example which shows a part upper end of the curtain cloth which stitched the interlining. A specific example showing an interlining according to the present invention. 9 is another specific example showing the interlining according to the present invention. Zigzag interlining.

  FIG. 1 is an embodiment showing a partial upper end of a curtain fabric 1 according to the present invention. The upper end of the curtain fabric 1 is folded to form a double structure, and an interlining 3 is sandwiched between the folded portions 2. . The interlining 3 is sewn to the upper end of the curtain fabric 1, so that the curtain fabric has rigidity. For this reason, hanging metal fittings can be attached to places to hang the curtain fabric. In this case, the interlining 3 is sewn without hanging between the hanging fittings by sewing.

  Incidentally, the interlining 3 generally has a weaving structure woven in a net shape using a warp and a weft, and various techniques relating to the interlining are conventionally known. For example, “decorative lace or decorative tape” according to Japanese Patent No. 4056354, and “corrugated tape for curtain forming a fold at the upper edge portion of the curtain and curtain using the same” according to JP-A-2002-119412. And "Interlining base material for curtain" according to JP-A-8-299161.

FIG. 2 is a specific example showing the interlining 3 of the present invention. In the figure, 4 denotes a warp, 5 denotes a weft, and a plurality of warps 4, 4 ... extending in the longitudinal direction at a constant interval are entangled with the wefts 5, 5 ... at an equal interval, and have a mesh shape of a constant width. To form a band. Generally, the warp 4 and the weft 5 are made of a polyester material or a nylon material.
The thick lines in the figure represent the shape retaining cords 6, and three shape retaining cords 6, 6, 6 are woven in the interlining 3 shown in the figure. That is, the shape retaining cords 6, 6, 6 are interlaced with the wefts 4, 4,.

  If the shape-retaining cord 6 is deformed into a predetermined shape, the shape-retaining cord 6 has a property of substantially retaining the deformed shape without completely restoring the original shape. Therefore, if the curtain fabric 1 shown in FIG. 1 is folded, the interlining 3 is also folded at the same time to form a zigzag shape, the shape is maintained, and the straightness is not straightened. When the curtain is stretched and closed by the zigzag at the upper end of the curtain fabric 1, the curtain fabric 1 forms pleats and undulates.

By the way, the specific material of the shape-retaining cord 6 is not limited.
The shape-retaining material is excellent in formability, dimensional stability, plastic deformability, shape retention after deformation, and can be used as a binding material having a large binding force. Therefore, an ethylene homopolymer having a density of 950 kg / m ³ or more, a weight average molecular weight (Mw) / number average molecular weight (Mn) of 5 to 15, and an α-olefin having 3 to 6 carbon atoms of less than 2% by weight or It is a fibrous or band-shaped molded article made of an ethylene / α-olefin copolymer, and has a return angle of 15 ° or less when bent by 90 °. Therefore, the shape-retaining cord 6 can be formed using this shape-retaining material.

Further, as another material of the shape retaining cord 6, a metal wire can be used. That is, a metal wire such as stainless steel is plastically deformed by an externally applied force, but if the force is removed, a part of the wire is elastically recovered. However, the amount of deformation that recovers elastically is small, and the plastically deformed metal wire is substantially maintained in that shape.
Therefore, the interlining 3 can be formed by weaving a stainless steel wire as a part of the warps 4, 4,....

  FIG. 3 is another specific example showing the interlining 7, and the basic structure is the same as the interlining 3 in FIG. The interlining 7 is also woven with a plurality of warps 4, 4,..., Which extend in the longitudinal direction at regular intervals, and are entangled with wefts 5, 5,. The shape holding cords 6, 6 are arranged at both ends of the interlining 7 to form a woven structure in which the wefts 5, 5,.

  By the way, the interlinings 3, 7 are generally configured as a woven structure composed of a warp and a weft, but may be a knitted structure. In this case, since it is difficult to simultaneously knit a thick shape retaining cord 6 or a metal shape retaining cord 6 with a knitting yarn, the shape retaining cord 6 is bonded to the surfaces of the interlinings 3 and 7. Can be done.

  The interlining 3 of the present invention is generally sewn to the upper end of the curtain fabric, but sometimes it is sewn to the lower end. Of course, the interlinings 3, 3 or 7, 7 may be sewn to both the upper end and the lower end. If the interlinings 3, 3 or 7, 7 are provided at the upper end and the lower end of the curtain fabric 1, a uniform pleat shape is formed from the upper end to the lower end.

  FIG. 4 is a schematic view showing the interlinings 3 and 7 when the curtain fabric 1 is folded to form pleats. The figure is a schematic view from above of the curtain fabric 1, but the interlinings 3, 7 form a zigzag shape when the curtain fabric 1 is folded, and do not extend straight. The shape retaining cords 6 incorporated in the interlinings 3 and 7 are simultaneously folded by folding the curtain fabric 1, and hold the interlinings 3 and 7 in a zigzag form as shown in FIG. I can do it. Elegant pleats are formed on the curtain fabric 1, and this shape does not collapse semipermanently.
