Description

The present invention relates to a curtain having a drape shape.

Conventionally, in the manufacturing process, a tuck is formed at the top of the curtain and a corrugated drape (please) is provided to enhance the decorative effect of the curtain. In addition, in a curtain in which such pleats are formed equally in the width direction of the curtain, and in order to stabilize it over a long period of time, a thermoplastic resin fiber such as polyester or a blended fiber thereof is used. In the manufacturing process, a shape stabilization process called heat setting is performed.

Conventional shape stabilization processing includes, for example, a method in which curtains to be processed after sewing are attached to a formwork one by one and heated, and then cooled, or in accordance with the tack on the top of the curtain and directed toward the bottom of the curtain. A ridge is formed, and along the portion between each of the tacks, a valley is formed so that a valley is formed. A method is introduced in which the processing means is stored in close contact with each other, heated from above and below using hot air, and similarly cooled from above and below with cold air as necessary (see, for example, Patent Document 1).

JP 2001-17309 A

However, although the conventional methods listed above have already been technically established, it is extremely time-consuming to attach and detach the curtains to be processed one by one to the formwork and the like. Therefore, it is extremely difficult to improve the efficiency of the manufacturing method and reduce the cost of the product.

Furthermore, there is an inconvenience that the mold must be prepared according to the width, number, or pitch of the folds provided on the curtain.

Furthermore, depending on the material of the curtain fabric, a preferred drape shape could not be imparted, and the lower portion of the upper drape shape spread out from the bottom, and a uniform preferred drape shape could not be obtained from the upper portion to the lower portion.

Moreover, by repeating washing, the heat setting effect of the skirt portion was lost, the skirt portion of the curtain was expanded, and the drape shape could not be maintained for a long time.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a curtain that can prevent the bottom of the curtain from spreading and can maintain its shape over a long period of time.

The curtain of the present invention, which has been made to solve the above-mentioned problems, has a film material that curls in one direction by applying heat after sewing the curtain, arranged on the interlining at regular intervals, and the interlining is arranged at the bottom of the curtain. The present invention has been completed by finding that the above-mentioned problems can be solved by attaching to the part.

That is, this invention consists of the following structures (1)-(4).
(1) A curtain in which a film material that curls in one direction by applying heat after curtain sewing is arranged on the interlining at regular intervals, and the interlining is attached to the bottom of the curtain.
(2) The film material that curls in one direction by applying heat after sewing the curtain is alternately arranged on the interlining at different intervals, and the interlining is attached to the skirt of the curtain (1 ) Curtains.
(3) The film material that shrinks by applying heat after sewing the curtain is alternately arranged on the front and back of the non-shrink film at regular intervals, and the non-shrink film is attached to the skirt of the curtain as a film core ( The curtain according to 1) or (2).
(4) The curtain according to any one of (1) to (4), wherein the film material that curls in one direction by applying heat after curtain sewing is formed by laminating a heat shrink film and a non-heat shrink film.

According to the present invention, since the curtain is a curtain in which a film material that curls in one direction by heat treatment is arranged at a fixed interval is attached to the bottom of the curtain, the stitched curtain is passed through a heating oven, The film material arranged on the curl can be curled to obtain a desired crease shape at the curtain skirt. Further, the shape can be maintained regardless of the material of the fabric constituting the curtain and after washing.

Hereinafter, preferred embodiments of the present invention will be described in detail. However, it should be understood that the present invention is not limited to only these embodiments, and that many modifications can be made within the spirit and scope of practice. I want.
In the curtain of the present invention, a film material that curls in one direction when heated after curtain sewing is arranged on the interlining at a fixed interval, and the interlining is attached to the skirt of the curtain.
The film material that curls in one direction by applying heat after curtain sewing of the present invention refers to a film material that curls in only one direction of either vertical or horizontal by applying heat after curtain sewing.
Specific examples include a uniaxially stretched heat-shrinkable film and a laminate of a uniaxially stretched heat-shrinkable film and a non-heat-shrinkable film. The heat-shrinkable film or non-heat-shrinkable film here means one that shrinks at the temperature of heat given after curtain sewing and one that does not shrink, and in particular, one that does not shrink at all. It doesn't mean only.

A laminate of a uniaxially stretched heat-shrinkable film and a non-heat-shrinkable film shrinks and curls only in the direction where the laminated surface of the uniaxially stretched heat-shrinkable film is not stretched by applying heat.
More specific examples of the heat-shrinkable film and the non-heat-shrinkable film include a laminate of a uniaxially stretched and shrinkable film and a biaxially stretched film.
The material of the film material is not particularly limited as long as the desired shrinkability and non-shrinkability can be obtained.

  The uniaxially stretched heat-shrinkable film and the non-heat-shrinkable film may be laminated by a known method, but may be bonded using an adhesive or the like. It is more preferable to use an adhesive that cures at room temperature.

  The film material that curls in one direction by applying heat after curtain sewing is cut according to the size of the drape (crease) and placed on the interlining at regular intervals, but the type of interlining is particularly limited However, a woven fabric, a knitted fabric, a nonwoven fabric, a film, etc. can be used. Further, the material is not particularly limited, such as polyester, nylon, cotton, and hair, but it is preferable that the material does not shrink by heat treatment performed after sewing.

Further, when the film material is arranged on the interlining at regular intervals, the film material is curled in the width direction of the curtain, and the film material is arranged at regular intervals so as to coincide with the stitches on the curtain top. It is good to arrange on the interlining.
The film material may be alternately arranged on the interlining by changing the curl direction at regular intervals. Changing the curl direction here means that the curl direction is the curtain width direction, but the curl direction is alternately arranged in the sense of the front side and the back side of the curtain.

  The film material may be alternately arranged on the front and back of the interlining. Also in this case, the curl direction is the width direction of the curtain, but the film materials are alternately arranged on the front and back of the interlining so that the curl direction is the front side and the back side of the curtain.

In particular, when a non-shrinkable film is used as the interlining, a film material consisting only of a heat-shrinkable film that shrinks in one direction in either the vertical or horizontal direction by heat applied after curtain sewing is used, and the film material is spaced at regular intervals. When the film is alternately arranged on the front and back of the non-shrink film and the non-shrink film is used as a film core, curling can be easily formed alternately on the front and back sides of the curtain. At this time, the curl direction of the film material is curled in the width direction.
In addition, what is necessary is just to affix on the film material to an interlining using an adhesive agent.

Such an interlining is attached to the bottom of the curtain. As an attachment method, it is possible to sew, or a means for holding a sack-like interlining at the skirt without sewing.
From the viewpoint of the drape shape (crease), the curtain is preferably provided with stitches at the top.
Moreover, the material which comprises a curtain main body is not specifically limited, such as polyester, cotton, and hair, The structure is not specifically limited, such as a woven fabric, a knitted fabric, and a nonwoven fabric.

The curtain in which the interlining is attached to the skirt portion of the curtain gives heat after sewing. This heat treatment causes the film material to curl in one direction and form a pleated shape at the skirt.
The temperature and time of the heat treatment are not particularly limited, and may be arbitrarily set according to the material of the curtain body, the material of the interlining, and the thermal characteristics of the film material curled in one direction.

EXAMPLES The present invention will be further described below with reference to examples, but the present invention is not limited to these examples.
