Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a curtain material having a woven pattern.

[Conventional technology]

Curtain fabrics with woven patterns are well known and widely used.

In this type of curtain fabric, in order to raise the pattern and make it stand out, thick warp and warp yarns are woven on the front side of the patterned area, and in areas other than the pattern, they are hidden behind the fabric and tied loosely. be.

[Problem that the invention seeks to solve]

In the case of a raised pattern made using a conventional technique, the surface of the raised part is flat and has no undulations, and this technique is well known and commonly used, so even if the composition or motif of the pattern is new, it will not look good. It does not necessarily attract the attention of the viewer, and the use of warp and warp yarns of different thicknesses is not welcomed because it complicates the management of the weaving process.

[Purpose of the invention]

Therefore, the present invention creates a new curtain fabric that arouses customers' desire to purchase by changing the weave structure of the fabric to create a three-dimensional pattern with a raised surface, regardless of the thickness or type of warp and warp threads. This is what we are trying to do.

[Structure of the invention]

That is, the curtain fabric 20 according to the present invention has a contour line 1
5, the inside of the enclosed area is wide enough to accommodate a circle with a diameter of 10 mm or more, and the outer fabric 17 has a flat weave and a dense warp density, and the lining has a desired weave structure and has at least a rougher warp density than the outer fabric 17. 18 are overlapped vertically, and a pattern having spaces 16 is woven by the ventilation structure in which the outer material 17 and the lining material 18 are connected at the contour line 15, and after weaving, at least the lining material of the spaces 16 is woven. 18
The back weft 14 of the fabric is treated to shrink, and the outer material 17 of the space 16 is characterized by randomly forming corrugated wrinkles 19 that continue for a long time in the warp direction.

The "dense ground surface 17" mentioned here refers to the outer surface 17.
This means that the fabric is woven so that there are no gaps between the warp and weft, and for this reason, the outer material 17 is woven with a plain weave. The structure is the front warp 11 and the front weft 13.
It may be a set of several pieces.

The curtain fabric 20 does not need to be composed only of the contour line 15 and the space 16, and the space 16 configured as described above may form a part of the curtain fabric 20. In other words, it is not necessary that the outer material 17 of the airy structure becomes a dense flat structure so that the portion 16 surrounded by the contour line 15 occupies the entire curtain fabric 20, and the pattern of the curtain fabric 20 is formed by the contour line 1.
5 and the space 16 may be constructed together with several types of parts 23, 23' having a weave other than the space 16, and the weave of the outline 15 does not need to be unified to one type.

Next, a preferred embodiment of the present invention will be described. The outline 15 is woven with a weft double weave, the warp density of the lining 18 is set to less than half the warp density of the outer material 17, and The weft density is also lower than the weft density of the outer material 17 to make the lining 18 coarser than the dense outer material 17. To achieve this, the outer material and the outer material of each of the contour line 15 and the space 16 forming the double weave are made to be coarse. In order to weave the lining separately, the wefts to be woven sequentially are divided into the front weft 13 and the back weft 14 and are woven alternately. The back weft 24 is the left and right contour line 15
It is preferable to connect it with the lining material 17 and insert it floatingly between the outer material 17 and the lining material 18.

In addition, it is reasonable to perform the shrinkage treatment of the back weft 14 at the same time as the immersion treatment in a dye bath during dyeing, and for this purpose, the back wefts 14 and 24 are coated with hot water shrinkable synthetic fibers that shrink in hot water. It is recommended to use

More preferably, the outer material 21 having a weft double weft structure forming the contour line 15 is woven by the weft 24 in the space 16 and the back weft 14 of the lining 18, and the lining 2
2 is a weft 14 woven by the front weft 13 of the outer fabric 17 in the space 16 to form the outer fabric and the lining;
24 and 13 are reversed between the contour line 15 and the space 16.

The wavy wrinkles 19 on the surface of the space 16 are caused by the airy structure of the outer material 17 being densely woven and the back weft 1
The higher the shrinkage rate of the back wefts 14 and 24, the better the formation.
Generally good results can be obtained when the shrinkage rate is equal to or greater than 3 and the shrinkage rate is 2% or more.

In addition, as long as the contraction occurs simultaneously in the front and back wefts 13, 14, 24 or only in the back wefts 14, 24, it does not necessarily need to occur in hot water.
Swelling agents other than hot water such as organic solvents or light may be used.

〔Effect of the invention〕

The lining 18 of the space 16 has a coarse warp density and has room to shrink in the weft direction as the back weft 14 shrinks.

On the other hand, since the outer fabric 17 has a flat structure with a dense warp density, there is no or little room for shrinkage in the weft direction, and even if the outer weft 13 shrinks, the lining 18
It cannot be contracted as much.

Therefore, when the wefts 13, 14, and 24 shrink, a difference in shrinkage in the weft direction inevitably occurs between the outer fabric 17 and the lining 18, and the space 16 of the outer fabric 17 is large enough to accommodate a circle with a diameter of 10 mm or more. Since it has a wide width, the outer material 17 tends to bulge as if being compressed by the left and right contour lines 15 due to the difference in shrinkage.

On the other hand, since the warps 11 and 12 do not shrink as much as on the left, the outer fabric 17 and the lining 18 in the warp direction
As a result, the surface warp 11 of the outer fabric 17, which does not shrink, prevents bulges in the weft direction, and as a result, the surface of the outer fabric 17 has undulations that continue in the warp direction. Wrinkles 19 will be formed.

At this time, if the contractile back weft 24 floats between the outer material 17 and the lining 18 without being intertwined with the warp 10, the shrinkage of the back weft 24 will occur linearly and greatly without being hindered by the warp 10. This promotes a tendency for the contour line 15 of the outer material 17 to be strongly compressed on the left and right sides and to bulge, thereby making the wavy wrinkles 19 even more noticeable.

The wavy wrinkles 19 formed in this way are due to contraction of the back wefts 14 and 24 and not to the contraction of the warp 10. Therefore, even if they disappear when tensioned in the weft direction, the warp On the other hand, since the curtain material 20 is hung with the warp direction aligned with the height direction of the curtain, the warp threads of the curtain material 20 are The wavy wrinkles 19 do not disappear due to the tension due to its own weight acting in the direction.

Generally speaking, when front wefts and back wefts with different shrinkage properties are woven into a double-layer outer fabric and a lining fabric, and the difference in shrinkage between these weft yarns is revealed after weaving, the fabric has high shrinkage. However, in the curtain fabric 20 according to the present invention, the outer fabric 1 in the space 16 where the difference in shrinkage occurs
7 and the lining 18 are vertically separated by the ventilation structure, and the difference in shrinkage is finely divided by the contour line 15 and does not occur continuously from one end of the curtain 20 to the other. , even if the back wefts 14 and 24 are more contractible than the front weft 13, the outer fabric 1
Curtain fabric 20 due to the shrinkage difference between 7 and lining 18
Unlike bimetallic or squid, the inconvenience of bending inside out does not occur.

In order to do this, as shown in the following example, the contour line 15 is densely woven with a double weave, and the front and back wefts 13 and back wefts 14 and 24 of the space 16 are reversed at the contour line 15. When the back wefts 14 and 24 form the outer fabric 21 of the contour line 15 and the front weft 13 forms the lining 22 of the contour line 15, the tendency of bimetal-like warping occurs between the contour line 15 and the space 16. On the other hand, the bimetal-like warping tendency does not continue unilaterally from one end of the curtain 20 to the other, and therefore the contour line 15
It is recommended that the weft yarns 14, 24 and the weft yarn 13 forming the outer material and the lining material are reversed between the front surface and the space 16.

As described above, the curtain fabric 20 according to the present invention has wavy wrinkles 19 surrounded by the contour line 15 and continuing long in the warp direction.
As a result, randomly raised spaces 16 are formed inside the pattern, thereby giving a three-dimensional effect to the pattern, thereby presenting a new aesthetic appearance that attracts the attention of customers from a technical perspective. The benefits are enormous.

〔Example〕

Polyester, filament yarn (50 denier/
1-24 filaments) are arranged as warps 10, 11, and 12 at a warp density of 93 filaments/cm, and the front weft 13 is made of polyester spun yarn (20
count single yarn), and the back wefts 14 and 24 are the front wefts 13
Using the same polyester spun yarn (number 10 single yarn) as above, weaving the front weft 13 and back wefts 14 and 24 alternately at a weft density of 15.75 threads/cm, the pattern shown in Figure 1 was created by (1) Space 16 The part shown in FIG. 4 has a ventilation weave consisting of a plain weave outer material 17 shown in FIG. 2 and a plain weave lining 18 shown in FIG. The front warp 11 and the back warp 12 are woven separately in a ratio of 5:1 with the lining 18, and the front weft 13 and the back weft 14 are woven separately into the front and back as shown in FIG. The weft threads 24 are not woven into the lining 18 but floated between the outer fabric 17 and the lining 18. It is constructed by a weft double weft structure consisting of a lining 22, and thereby the front warp 11 and the back warp 12 of the space 16, and the front weft 13 and the back weft 14, 24 as shown in FIGS. 7 and 8. The ventilation structure of the space 16 is bound by joining at the contour line 15, (3) The part of the contour line 15' is made from the outer material of the woven structure shown in FIG. 9 and the lining material of the modified plain structure shown in FIG. 10. The front warp 11 and the back warp 12 of the space 16 and the front weft 13 and the back weft 14 and 24 are connected in the same way as in the case of the contour line 15, thereby creating a wind pattern in the space 16. (4) The part of the space 23 is bound by the warp 1 by the ventilation stitch consisting of the outer fabric 17' made of satin fabric shown in FIG. 11 and the lining fabric 18' made of plain fabric shown in FIG. 12.
0 is divided into front and back warp threads 11 and back warp threads 12 so that the number of threads is 5:1 for the outer material 17' and lining material 18', as shown in FIG. As shown in Fig. 13, the front and back wefts are woven separately, and every other back weft 24 is not woven into the lining 18 but floated between the outer fabric 17 and the lining 18. (5) The space 23' is woven as shown in Fig. 14. The weft yarns 13 on the front and back sides are woven in hot water during the dyeing process of the curtain fabric 20 woven in this way. 14 and 24 showed contractility.

As a result, wavy wrinkles 19 were formed on the surface of the outer material 17 in the space 16.

On the other hand, similarly to the space 16, although the front warp 11 and the back warp 12 and the front weft 13 and the back wefts 14 and 24 are woven separately on the front and back sides and woven with an airy weave, it is not woven with a plain weave but with a satin weave. No wavy wrinkles 19 were formed on the surface of the outer material 17' of the space 23 where the space 23 had been removed.
