Description

  The present invention relates to a fusion fabric obtained by combining a jacquard weave and a leno weave, and a method for weaving the fusion fabric.

  There are many types of cars today, and various materials are used for car seats. There are broadly divided fabric and leather fabrics, but in any case functions such as car seats such as safety, ride comfort, ease of driving, and ease of getting on and off are not impaired. Must be dough. Further, durability is required for covering the surface of the car seat, and further fading resistance and light resistance are also required.

Japanese Patent Laid-Open No. 2011-231439 “Metal-deposited slit yarn, fabric and car sheet resistant to sunlight degradation due to sunlight” does not change the metallic luster of the metal-deposited yarn by sunlight for more than 5 years, and its decorative properties It is the cloth for car seats in which the metal vapor-deposited yarn capable of maintaining the above is part of the material structure.
Therefore, a laser slitter is used to obtain a thread with a synthetic resin layer containing an ultraviolet absorber on the outermost layer of a slit thread that has at least one metal-deposited surface and is protected on both sides with a plastic film. As part of it.

“Car seat twisted yarn and car seat fabric using the same” disclosed in JP-A-2001-214340 are car seat fabric that can be manufactured at low cost with less processing loss, and twisted yarn used for the manufacture thereof. is there.
Two yarns are crossed in an X shape on a stretchable yarn B (for example, polyester) and double-covered, and at least one of the crossed yarns is a low melting point yarn B (for example, nylon). Features. Since A is a core, B is S-twisted, and C is wound with Z-twist, B and C intersect to form an X shape. The car seat fabric of the present invention is woven using 5% or more of the total weft yarn.

In this way, there are various car seat fabrics. However, when using fabric fabrics, if cut according to the size and shape of the car seat, the cuts will fray and decompose, and warp yarns in the intermediate process In addition, weft misalignment occurs.
As a technique for preventing fraying disassembly and misalignment of the cut end of the cut fabric, there is known a “method for weaving a woven fabric with plain weave and entangled weave and a loom for carrying out the method” according to JP 2006-518421 A ing.

That is, a single weave can be used to obtain a plain weave (Jacquard weave) and an entangled weave in one weaving cycle, thus saving on an expensive opening member. In order to achieve this object, a plain weave and an entangled weave are simultaneously formed in one weaving cycle in accordance with the present invention.
To form a plain weave, the adjacent warp yarns used for forming the upper and lower mouths are alternately pulled up from the lower mouth position to the upper mouth position by the same blade and needle frame, and from the upper mouth position to the lower mouth position. Pulled down. In order to form an entangled weave, only the warp yarns that form the upper mouth are pulled up from the lower mouth position to the upper mouth position and lowered from the upper mouth position to the lower mouth position, as is known.

However, the fabric for car seats is required not only to have functions that can prevent fraying and disassembly of the cut but also to have a design that provides a good appearance. Therefore, the woven fabric according to the above-mentioned special table 2006-518421 is not suitable for the fabric for car seats.
“Metal-deposited slit yarn, fabric and car seat having resistance to degradation of brightness due to sunlight” according to JP 2011-231439 A "Car seat twisted yarn and car seat fabric using the same" according to JP-A-2001-214340 “Looming machine for carrying out the method and method of weaving a woven fabric with plain weave and entangled weave” according to JP-T-2006-518421

  As described above, the car seat fabric composed of a woven fabric has the above-described problems. The problem to be solved by the present invention is this problem, and provides a fusion woven fabric that does not fray and disassemble the cut edges of the cut fabric and has a favorable appearance design. However, the use of the fusion fabric is not limited to the fabric for car seats.

The fusion fabric according to the present invention is configured by fusing a jacquard fabric and a calami fabric together. Here, the jacquard fabric has a woven structure in which warps and wefts are alternately woven, and the calami fabric forms a set of warps with respect to the wefts, and the plurality of warps are intertwined with the wefts while twisting each other. Has a woven structure.
The present invention can constitute a woven structure in which the jacquard fabric and the calami fabric are woven and fused on the same loom.

  By the way, the jacquard fabric is woven using a jacquard device, and the dough device is used for the calami fabric, but the calami folds and the jacquard folds are mounted on the same loom, and the warp is controlled for weaving. Here, a design paper is prepared in a double woven fabric or a structure form equivalent thereto, and the weft is inserted by operating the warp. In order to overcome the difference in the structure of the loom due to the peculiarity of the calami fabric, they are arranged on the same loom.

The fusion woven fabric of the present invention has a woven structure in which a jacquard woven fabric and a calami woven fabric are fused with each other, and therefore, when cut into a predetermined size and shape, the cut end is not frayed or disassembled. . In other words, the weaved warp and weft are effectively acted on by the calami weave formed inside the fabric to prevent misalignment.
Therefore, it is not necessary to apply a resin coating to the back of the fabric in order to prevent fraying decomposition and misalignment, and the durability of the fabric is increased. For example, when used for a fabric of a seat cover, its life is greatly improved.

And the fusion woven fabric of the present invention is designed with various shapes and patterns of warp and weft by the jacquard woven structure, this jacquard woven structure is held by the calami woven structure, and therefore the appearance of the fused woven fabric is good, Moreover, durability is improved. Therefore, it is also suitable as a car seat fabric.
Furthermore, the fused fabric of the present invention has high productivity because the jacquard fabric and the calami fabric are woven together by the same loom.
On the other hand, in order to prevent fraying decomposition and misalignment, the dough is lightened by not coating the resin on the back surface as in the conventional case, the manufacturing cost is reduced, and no environmental problems are caused by not using the resin.

An example showing a loom for weaving a fusion fabric. The schematic diagram of the apparatus which weaves a fusion fabric.

  FIG. 1 is a specific example showing a woven structure of a jacquard woven fabric, where 1 is a weft and 2 is a warp. A plurality of warps 2, 2... Are arranged at regular intervals, and the wefts 1, 1. The warp yarns 2, 2... Are moved upward and downward and opened, and the weft yarns 1, 1. By controlling, the texture can change in various ways. That is, the jacquard texture can form various figures and patterns.

  FIG. 2 is a specific example showing a woven structure of a calami woven fabric, where 3 represents a weft and 4 represents a warp. The weaving structure of the calami fabric has a structure in which the weft 3 is sandwiched between the two warps 4, 4 in a state where the two warps 4, 4 are twisted together. That is, the two warps 4, 4... Are twisted with each other to form a string structure, and the weft 3 is entangled with the weft 3 being sandwiched between the two warps 4, 4.

  In such a calami weave structure, the weft 3 is sandwiched between the two warps 4 and 4 twisted to each other, so that the warps 4 and 4 and the weft 3 are restrained at a predetermined position without being displaced. Here, the number of the warps 4 intertwined with the wefts 3 is not limited to two, and the twisted structure of the warps 4, 4 is not limited.

FIG. 3 is a specific example showing the woven structure of the fusion fabric according to the present invention. The woven structure of the fusion fabric constitutes a structure obtained by fusing the woven structure of the jacquard woven fabric shown in FIG. 1 and the woven tissue of the calami woven fabric shown in FIG. The woven structure of the fusion woven fabric shown in the figure has three wefts 3, 3, 3 constituting a calami weave structure and six wefts 1, 1,... Constituting a jaguar woven structure. , 3 have two wefts 1 and 1 interposed.
The warp 2 intersects with the wefts 1, 1... And also intersects with the wefts 3, 3. Further, a twisted warp 5 in which two warps 4, 4 are twisted in a pair sandwiches the wefts 3, 3,... With both warps 4, 4, but the weft constituting the jacquard weave structure. It is not entangled with 1, 1.

That is, the calami weave structure is disposed on the lower surface side of the jacquard weave structure, and the warp yarns 2, 2... The wefts 3, 3 ... are crossed in some places.
For example, in FIG. 3, the warp yarn 2a having a jacquard woven structure is located below the weft yarn 3a having a calami woven structure and located above the other weft yarns 3b and 3c. On the other hand, the warp yarn 2b of the jacquard weave structure is located below the weft yarn 3b of the calami weave structure, and is located above the other weft yarns 3a and 3c.

Here, the number of the jacquard wefts 1 arranged between the wefts 3 and 3 of the calami weave is not limited, and the weft of the figure is composed of warps 4 and 4 twisted in pairs. Between the twisted warps 5 and 5, two warps 2a and 2b are arranged. However, the number of twisted warps 5 and 5 and the number of warps 2a and 2b are not particularly limited. The present invention is not limited to the case of the calami tissue, the woven tissue, and the fusion method, as described in the examples.
By the way, this new fusion fabric has a double weave structure. By adding a calami structure on the back, no calami structure appears on the front surface, and the expression of a conventional jacquard fabric with excellent design is achieved. Maintained.

  For example, in a jacquard fabric, a calami structure composed of two warps 4, 4 can be added to one place between ten warps 2, 2,. When this is boiled, the warp yarns 4, 4 of the calami texture contract, and the warp yarns 2, 2,... Of the jacquard fabric loosen. A woven fabric is completed.

Since the warp yarns 4, 4 ... of the calami structure contract, the stretchability is increased, and the weft yarns 3, 4 ... are entangled with the weft yarns 3, 3 ..., so that the fraying decomposition and misalignment are reduced. Is done.
The warp yarns 4, 4... Of this calami weave structure can freely select the wefts 3, 3... It is possible to freely select and designate the wefts 3, 3.

  Furthermore, in addition to the design of the conventional jacquard fabric, if you show the calami structure on the surface, you can express the new appearance of the calami structure that flows diagonally, and there is a woven structure with a new design that has never been seen before It is formed. A conventional jacquard fabric is a flat continuous fabric in which warp and weft intersect at right angles, but by fusing the calami structure, the warped warp becomes a surface and can have different designs.

  FIG. 4 is an external view showing a loom for weaving a fusion fabric (a fabric in which a jacquard fabric and a calami fabric are fused) according to the present invention, and is configured by adding a calami weaving device 6 to the jacquard loom. The loom includes an existing rapier loom 7 and a jacquard opening device 8, a dobby opening device 9 with a servomotor, a calami wrinkle device 10, and a jacquard threading device 11.

This new fusion fabric is woven simultaneously on the same loom with fabrics having two types of tissue forms with different weaving methods.
