Abstract

PURPOSE:To obtain woven fabric having a three-dimentional pattern rich in volume feeling by making woven fabric comprising plural layers having different crimping properties and dyeing. CONSTITUTION:Wool weaving yarn is used in a lower layer 1, nylon weaving yarn in a middle layer 2 and polyester weaving yarn in an upper layer 3 and woven fabric of three-layer structure having partially formed an interlaced part 4 wherein the weaving yarns are partially entangled and a liberated part 5 wherein the weaving yarns are mutually separated is woven by using a jacquard machine. Then in a first process, the upper layer 3 of the woven fabric is subjected to transfer printing by using transfer print paper at high temperature in a short time to color the constituent polyester weaving yarn. Then the whole woven fabric is immersed in a dyeing solution at a relatively low temperature, the wool weaving yarn of the lower layer 1 is dyed and crimped. At the liberated part 5, difference in degree of tension between the polyester weaving yarn of the upper layer 3 and the wool weaving yarn of the lower layer 1 is produced by the crimping of the wool yarn to raise the upper layer 3 by the difference.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dyed fabric and a method for producing the same.

0002

[Prior Art] Traditionally, woven fabrics have only been made up of layers of the same material, but they are woven to form multiple layers using different yarns, forming partially three-dimensional patterns. The current situation is that the product has not been commercialized.

0003

[Problem to be Solved by the Invention] The reason for this is that when woven items made of different yarns are dyed, one of the yarns may be crimped depending on the crimpability of the different yarns, resulting in uneven dyeing. This is because sex is lost. On the other hand, textiles have a wide range of uses, including clothing, bedding, and chair seats.
If it is possible to vary the decorativeness of the textile itself, it is possible to easily vary the decorativeness of clothing and the like manufactured using the textile.

Therefore, the present invention not only forms a three-dimensional pattern, but also provides rich decorative variation and a sense of volume by using a fabric woven from yarns with different crimp properties. The purpose is to provide a dyed fabric and a method for producing the same.

[0005]

[Means for Solving the Problems] In order to achieve the above object, the present invention comprises a plurality of layers, and a woven portion is formed in which the threads of each layer are woven so as to be partially entwined with each other. , the lower layer is crimped at a low temperature, and the upper layer is dyed at a higher temperature than the crimping temperature of the lower layer.

[0006] In addition, it is composed of a plurality of layers, and a woven part is formed in which the threads of each layer are woven so that they are partially entwined with each other, and the material of the threads forming the upper layer is different from the material of the threads forming the lower layer. It can be dyed at a higher temperature than the thread material,
For a fabric whose lower layer can be crimped at a low temperature, the upper layer is dyed at a high temperature in the first step during a period in which the lower layer does not crimp, and the lower layer is crimped in the second step.

[0007]

[Function] In the present invention, the material of the yarn constituting the upper layer is dyed at a higher temperature than the material of the yarn constituting the lower layer,
Since the lower layer is crimped at a low temperature, the threads that make up the upper layer are dyed, and only the threads that make up the lower layer are shrunk, creating a difference in tension between the upper and lower layers, which causes them to be loose. The upper layer in the area appears to stand out, forming a three-dimensional pattern.

[0008]

[Embodiment] An embodiment embodying the present invention will be described below. As shown in Fig. 4, the dyed fabric of this example is woven using a jacquard machine and has a three-layer structure, in which the lower layer 1 is made of wool yarn, the middle layer 2 is made of nylon yarn, and the upper layer 3 is made of polyester yarn. . Note that wool yarn is dyed at a relatively low temperature and has the property of shrinking at a relatively low temperature. Polyester yarns are dyed at relatively high temperatures and have the property of shrinking at relatively high temperatures.

As shown in FIGS. 2 and 4, the materials of each layer 1, 2, and 3 are partially woven so that the threads are entangled with each other to form a woven portion 4, and other parts are loosely woven from each other. This forms a free part 5. In the free part 5, the wool yarn of the lower layer 1 is shrunk compared to the polyester of the upper layer 3, so it looks raised and forms a three-dimensional pattern. In addition, the nylon of the middle layer 2 gives a sense of volume to the entire fabric, and particularly enhances the prominence of the free portions 5. A pattern is printed on the surface of the upper layer 3 polyester (omitted from the drawing)
.

The fabric of this example not only has a three-dimensional effect, but also
Since it has a printed pattern, it has a very gorgeous atmosphere. If such fabrics are used for blousons, chair upholstery, bed covers, etc., it is possible to easily produce items that have a very luxurious and gorgeous feel. Next, a method for manufacturing the dyed fabric of this example will be explained.

As shown in Figures 1 and 3, it has a three-layer structure in which the lower layer 1 is wool yarn that can be crimped at low temperatures, the middle layer 2 is nylon yarn, and the upper layer 3 is polyester yarn that can be dyed at high temperatures. There is a woven part 4 in the material of each layer 1, 2, 3.
and free portions 5 are partially formed, and each layer 1, 2,
All 3 overlap with almost the same tension without shrinking. Transfer is performed on this state at high temperature (approximately 200° C.) and high speed (30 seconds/m) using transfer print paper (for example, Dry Print, trade name, manufactured by Dainippon Printex Co., Ltd.). In this case, since they overlap with almost the same tension, the print is transferred neatly. Note that since printing is performed at a high temperature, the lower layer 1 is not affected to the extent that it is crimped.

Next, the dye is dissolved at a relatively low temperature (approximately 12
The wool is dyed by soaking the entire fabric in hot water (0°C). Since it is heated, although at a low temperature, the wool of the lower layer 1 is crimped as shown in FIGS. 2 and 4. At this time, the yarns of the layers 1, 2, and 3 are interwoven with each other in the weaving section 4, so that when the wool of the lower layer 1 shrinks, the polyester of the upper layer 3 also shrinks. However, in the free part 5, the upper layer 3 polyester and the lower layer 1
There is a difference in the tension of the wool, and the polyester of the upper layer 3 in the free area 5 appears to stand out accordingly. In this case, only wool can be dyed by using an acid dye or an acid mordant dye.

In this embodiment, when applying a pattern to the upper layer 3, since transfer printing paper is used, the printing is instantaneously heated to a high temperature. Since each layer 1, 2, and 3 is printed while being overlapped with almost the same tension without shrinking, it is possible to print neatly. Furthermore, since the printing is instantaneous, the wool of the lower layer 1 does not become crimped. Here, if a pattern is to be applied to the upper layer 3 using multicolor printing using screen printing, printing will be performed multiple times, so
The printing time becomes longer and the lower layer 1 is also affected by heat, causing the materials of each layer 1, 2, and 3 to shrink, resulting in misalignment of the pattern, but in the case of print printing, multiple prints can be made in one printing. Since it can be printed in color, there will be no misalignment of the pattern.

It should be noted that the present invention is not limited to the embodiments described above, and may be modified as desired without departing from the spirit thereof, for example, as follows. (a) For the upper layer, in addition to polyester, nylon etc.
Use materials that are dyed at high temperatures and shrink at high temperatures. (b) For the lower layer, use materials other than wool, such as rayon, cotton, linen, etc., that are dyed at low temperatures and are crimped at low temperatures.

(c) Consisting of an upper layer and a lower layer without providing an intermediate layer. (d) As part of the crimping process, the entire fabric is simply soaked in hot water without dyeing the underlying material. Although not directly related to the present invention, the temperature is higher than the temperature at which the material constituting the lower layer can be dyed and shrinks without printing the upper layer, and the temperature at which the material constituting the upper layer can be dyed and shrinkable. It is also conceivable to perform the heat treatment at a temperature lower than that temperature.

Effects of the Invention As detailed above, according to the woven fabric and manufacturing method of the present invention, not only a three-dimensional pattern can be formed, but also decoration can be achieved by using a woven fabric woven from yarns with different crimp properties. It has an excellent effect of being rich in variety and giving a sense of volume.
