The present invention relates to a three-dimensional woven fabric and a method of producing the same and, more particularly, to a three-dimensional woven fabric woven with threads into a woven fabric for blinds having a mesh-structured front layer, a mesh-structured rear layer, and a light shielding layer blocking light which can be woven by a single weaving machine and a single process, which have a changeable shape between a planar shape and a three-dimensional shape, and which can be used for a blind, and a method of producing the same.
In general, a curtain, a blind, or the like is installed on a window and/or an entrance and is used to block solar light and another's eyes and for the purpose of noise-proof, cold wind-proof, and the like, and in addition to these utilities, also serves as an important house-furnishing good to enhance interior esthetic appearance by mixing colors to match up an inner wall and window glasses.
An existing three-dimensional blind is disclosed as a blind, in U.S. Pat. No. 3,384,519, made by forming dual mesh-structured woven fabrics, disposing a movable blade therebetween, and bonding the mesh-structured woven fabrics with the blade.
The above-mentioned method controls quantity of light such that light enters inside through the mesh-structured woven fabrics when the blade change a pose into a horizontal pose, and that the blade returns to the vertical pose to block light through the mesh structure of the woven fabric. However, bonding between the blade and the woven fabrics by adhesive may be an interior pollution source and further property of the adhesive may be deteriorated by ultraviolet rays for a long use so that the bonding may be inferior and the blade and the woven fabrics may be separated from each other.
In order to overcome these disadvantages, Korean Patent No. 815579 proposed a three-dimensional woven fabric including a surface layer, a rear layer, and an intermediate layer connecting the surface layer to the rear layer by weaving. However, the disclosed three-dimensional woven fabric is made by forming a first intermediate layer and a second intermediate layer with two wrap threads to be connected to the surface layer and the rear layer and thus has a simple expression and a limit to block light.
Therefore, the present invention is made to solve the above problems.
In accordance with the present invention, a three-dimensional woven fabric including a light-transmittable front layer, a light-transmittable rear layer, and a half light-transmittable light-shielding layer connecting the front layer to the rear layer and a method thereof are provided. The light-shielding layer is formed by repeatedly overlapping first, second, and third light-shielding layers, with adjacent ones among first to third layers overlapped. In the front layer, are sequentially and repeatedly formed front parts in which front layer wrap threads and front layer weft threads are woven and front layer-connecting parts in which front layer wrap threads, front layer weft threads and the light-shielding layer's light-shielding layer wrap threads are woven. In the rear layer, are sequentially and repeatedly formed rear parts in which rear layer wrap threads and rear layer weft threads are woven and rear layer-connecting parts in which rear layer wrap threads, rear layer weft threads and the light-shielding layer's light-shielding layer wrap threads are woven. The light-shielding layers are formed by weaving light-shielding layer wrap threads and light-shielding layer weft threads, and the light-shielding layers are sequentially and repeatedly connected to the front layer-connecting parts and the rear layer-connecting parts.
According to the present invention, a woven fabric in which a three-dimensional shape may be implemented only by weaving without glue or adhesive may be provided.
In addition, the present invention may provide a three-dimensional woven fabric capable of expressing various design according to change of a three-dimensional shape and of blocking light.
The present invention provides a three-dimensional woven fabric comprising: a front layer, a rear layer, and a light-shielding layer connecting the front layer to the rear layer. The light-shielding layer is repeatedly overlapped with another light-shielding layer adjacent to a first light-shielding layer, a second light-shielding layer, and a third light-shielding layer. The front layer includes front parts, in which front layer wrap threads and filings are basically woven, and first to third front layer-connecting parts, in which front layer wrap threads and wrap threads and filings forming the light-shielding layer are woven, which are sequentially and repeatedly formed. The rear layer includes rear parts, in which rear layer wrap threads and filings are basically woven, and first to third rear layer-connecting parts, in which the rear layer wrap threads and wrap threads and filings forming the light-shielding layer are woven, which are sequentially and repeatedly formed. The first to the third light-shielding layers are formed by weaving the wrap threads and the filings forming the light-shielding layer. The first to third light-shielding layers are connected to the first to third front layer-connecting parts and the first to third rear layer-connecting parts sequentially and repeatedly. The third rear layer-connecting parts are disposed on the rear layer facing the first front layer-connecting part of on the front layer. The first rear layer-connecting part is disposed on the rear layer facing the second front layer-connecting part on the front layer. The second rear layer-connecting part is disposed on the rear layer facing the third front layer-connecting part on the front layer. The first to the third rear layer-connecting parts are longer than the first to the third front layer-connecting parts and shorter than distances between the first to the third front layer-connecting parts, and the light-shielding layer connected to the respective rear layer-connecting parts is overlapped with another light-shielding layer connected and adjacent to a front layer-connecting part directly above a next-next rear layer connecting part.

In view of a path through which the light-shielding layer wrap threads are woven, the first light-shielding layer wrap threads 310 repeat a process of forming the first front layer-connecting parts 111 in association with the front layer wrap threads 101 and the front layer weft threads, being exposed out of the front part 120 up to starting points of the second front layer-connecting parts 112 without crossing with weft threads, passing through the third light-shielding layers 500 and crossing to the rear layer 200 to form the first rear layer-connecting parts 211 in association with the rear layer wrap threads 201 and the rear layer weft threads, being woven to the light-shielding layer weft threads to form the first light-shielding layers 300, and forming the first front layer-connecting parts 111 at the next position.

Thus, since the respective light-shielding layer wrap threads are simply woven up to the starting points of the rear layer-connecting parts without the weft threads after forming the front layer-connecting parts, the exposed wrap threads have to be sheared as illustrated in
The above-described three-dimensional woven fabric may be produced by a method as described below.
The front weft threads are woven to the front layer wrap threads 101 to form the front layer 100.
The front layer 100 and the rear layer 200 are sequentially and repeatedly connected to the first light-shielding layers, the second light-shielding layers, and the third light-shielding layers, which are woven with the light-shielding layer wrap threads and weft threads, while the rear layer weft threads are woven to the rear layer filings 201 so as to form the rear layer 200 in the state of being spaced apart from a preset distance D3 from the front layer 100 to be parallel thereto, wherein

the third light-shielding layer wrap threads 510 repeat a process of forming the third front layer-connecting parts 113 in association with the front layer wrap threads 101 and the front layer weft threads, being exposed out of the front part 120 to starting points of the first front layer-connecting parts 111 without crossing with weft threads, passing through the second light-shielding layers 400 and crossing to the rear layer 200 to form the third rear layer-connecting parts 213 in association with the rear layer wrap threads 201 and the rear layer weft threads, being woven to the light-shielding layer weft threads to form the third light-shielding layers 500, and forming the third front layer-connecting parts 113 at the next position, and,
after weaving, the light-shielding wrap threads exposed to the outside of the front layer are removed to produce the three-dimensional woven fabric.
In the above-description, the distance D3 between the front layer and the rear layer is employed for the better comprehension of the drawings, but actually, the layers are adjacent to each other as illustrated in
In the above-description, the light-shielding wrap threads are exposed to the outside of the front part, but actually, the light-shielding wrap threads may be provided at the outside of the rear part. Since the front layer and the rear layer are reversed according to a view direction, that is, when the woven fabric is reversed after weaving the fabric, this should be fall in the scope of the present invention.
If the weaving of the fabric according to the present invention were expressed by the number of healds simply, if it is assumed that the healds No. of the wrap threads of the front layer is 1/2, the healds No. of the wrap threads of the rear layer is 3/4, the healds No. of the wrap threads of the first light-shielding layer is 5/6, the healds No. of the wrap threads of the second light-shielding layer is 7/8, and the healds No. of the wrap threads of the third light-shielding layer is 9/10; the front part and the rear part are basically woven by the healds Nos. 1/2 and 3/4 respectively, the first connecting part of the front layer is woven by the healds Nos. 1/2/5/6, the second connecting part of the front layer is woven by the healds Nos. 1/2/7/8, and the third connecting part of the front layer is woven by the healds Nos. 1/2/9/10; and the first connecting part of the rear layer is woven by the healds Nos. 3/4/5/6, the second connecting part of the rear layer is woven the healds Nos. 3/4/7/8, and the third connecting part of the rear layer is woven by the healds Nos. 3/4/9/10.
In the embodiment, although the first to the third rear layer-connecting parts 211, 212, and 213 have the same lengths as those of the first to the third front layer-connecting parts 111, 112, and 113 as illustrated in
In still another modified embodiment, as illustrated in
In the embodiment, the dense weaving of the light-shielding layer is to form the light-shielding structure by making the density of the weft threads high or using thick weft threads because thickness and density of the light-shielding wrap threads are uniform. According to the present invention, since the light-shielding layers are overlapped doubly, the light-shielding layers have a half-light-shielding structure such that light is completely shielded when the three-dimensional woven fabric is fully folded (See
Even in the modified embodiment and another modified embodiments, like in the embodiment, since the light-shielding layers are overlapped doubly, the light-shielding layers have a half-light-shielding structure such that light is completely shielded when the three-dimensional woven fabric is fully folded (See
