Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION This invention relates to a curtain fabric, and more particularly to a high quality double curtain fabric which has a pleated appearance and is excellent in light-shielding properties, heat insulating properties and aesthetics.

[0002]

2. Description of the Related Art Although there are various kinds of curtains, blind-like so-called pleated curtains have been developed and put into practical use in recent years.

As shown in FIG. 1, the pleated curtain is a bellows-shaped form in which a cloth is alternately folded into a width of 10 to 50 mm, and is more decorative than the conventionally used Venetian blinds. However, there is a problem in that it lacks functions such as light shielding and heat insulating properties.

On the other hand, recently, a tubular body made of a non-woven sheet or cloth having a rhombic cross section is spliced on one side thereof with an adhesive in order to form a bellows shape, but the manufacturing process is complicated. However, there are various technical problems such as limitation in size.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above problems of the prior art. Particularly, the manufacturing is easy and there are no size restrictions, and the light shielding property, heat insulating property, aesthetics, etc. An object of the present invention is to provide a high-quality double-curtain fabric excellent in

[0006]

SUMMARY OF THE INVENTION The present invention has a plurality of bag-shaped portions formed via linear binding portions provided at regular intervals in one direction, and the linear binding portions are provided near both ends. A cloth for a curtain, characterized in that the fork, which is discontinuous at the non-binding portions at regular intervals and is also discontinuous at the non-binding portion for the small holes inside thereof, is made of a knitting structure. Is.

A plan view and a cross-sectional view of the curtain fabric of the present invention are shown in FIG. 2 for a woven fabric example. The curtain fabric (1) of the present invention can be woven by a generally known double weave using the warp yarn (2) and the weft yarn (3). Also, in the case of a knitted product, it is possible to similarly knit by a generally known double knitting.

[0008] The bag-like portion (5) through the linear binding portion (4)
Is formed. The linear binding part (4) is discontinuous by the non-binding part (8), leaving the ears (6) at both ends. The length of the non-binding portion near both ends is 10 to 20.
About mm is preferable. The interval between the adjacent linear binding portions (4), that is, the cross-sectional length of the bag-shaped portion is preferably about 10 to 50 mm.

The linear binding portion (4) further has a non-binding portion (7) for small holes in a part thereof. This small hole serves as a string through hole for passing the lifting cord when opening and closing the curtain. The position and number of the string through holes are arbitrary, but it is desirable that they are symmetrically provided at a position relatively close to the non-binding part (8).

The type of fiber used for this is not particularly limited, but pleated synthetic fibers such as polyester fibers and polyamide fibers are preferred. When weaving a fabric, a curtain having different appearances and functions on the front and back sides can be produced by changing the fibers and the weave or knitting structure on the front and back sides of the fabric.

Further, the fabric of the present invention is provided with a variety of decorative properties by using dyed yarn or by dyeing or printing after weaving or knitting, and the surface and / or back surface of the fabric. It is also possible to impart a higher degree of decorativeness and functionality by subjecting a resin agent or the like to coating, vapor deposition, or adhesion of various films to a resin agent or the like, for example.

The curtain fabric of the present invention having the above-mentioned structure is made into a curtain as follows.

The fabric is cut in the sub-direction at substantially the center of the non-binding portion (8) near both ends. Next, each bag-shaped portion is spread in the direction of the front and back of the cloth, and hot pressed to form pleated creases facing the front and back of the cloth. In this way, the bag-shaped portion has a rhombic shape shown in FIG. 3, but it may be formed into another shape by inserting a hexagonal shape-like metal mold into each bag-shaped portion and performing thermoforming. It is possible.

It is desirable to improve the shape retention by resin processing prior to hot pressing. In addition, flame-retardant fibers may be used or flame-retardant processing may be performed with a cloth.

In this way, a bellows-shaped product can be produced, and a string through hole is arranged at a predetermined position of each binding portion. By folding the cut part and stitching it,
Curtain ears are formed that are excellent in appearance and have no physical defects such as fraying.

The curtain made from the curtain fabric of the present invention does not require an adhering work such as sequentially joining the preformed tubular bodies, and the whole is composed of one woven fabric, so that the quality durability It will be an excellent product.

Further, since it is possible to create a curtain of any size, and since the string through hole is made of a fabric structure, it is not necessary to carry out the perforating work, and the thread may be frayed during use. It is excellent in appearance and quality.

Further, since the curtain fabric of the present invention has a cut portion composed of a non-binding portion in the vicinity of the end portion, by sewing the front and back ears together after cutting, an ear excellent in physical properties and aesthetics is obtained. It can be a curtain with parts.
Of course, as a result of having a bag-shaped double structure, it also has a feature that it is far superior in light-shielding and heat-insulating properties to conventional cloth curtains.

The cloth curtain of the present invention is usually used by vertically expanding and contracting the bellows structure as shown in FIG. 3, but it can also be used by laterally expanding and contracting.

The place of use is also arbitrary,
It can be used in offices, vehicles, etc. wherever light shielding, heat insulation, and aesthetics are required.
