DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative fabric, and more particularly to a decorative fabric which has been colored by an ink jet method, that is, an ink jet printer.

[0002] In the present specification, the term "designed fabric" in the present invention means a woven fabric provided with a pictorial pattern or a pattern, including the description in the claims. In this specification, “color painting” refers to “construction of a multicolor (including two colors) painting-like pattern or pattern”.

Recently, color printing by the ink jet method has come to appear. This type of color print is a color print that expresses a color with a set of fine ink points of yellow, magenta, cyan, and black.

[0004]

2. Description of the Related Art Conventionally, color printing of this type uses a certain special ink to obtain good color expression.
The reality is that it can only be achieved on a certain type of paper, and has not been applied to the color painting of textiles.
The reason is as follows.

[0005] When an existing ink for an ink jet printer is printed on an ordinary fabric by an ink jet method, fine particles of the ink are mixed on the fabric and a good color is not developed. By the way, according to the experimental results of the present inventors,
In the case of multicolored color painting, only poor appearance of blackening was obtained. The fact that the color is darkened is nothing less than a mixture of ink particles of different colors on the fabric. Black is expressed as a mixture of three colors of yellow, magenta and cyan.

[0006]

SUMMARY OF THE INVENTION The present invention seeks to achieve color painting of textiles by an ink jet printer without the problems described above and without the problem of color bleeding. When this object is achieved, the usefulness of color printing by an ink jet printer, that is, particularly suitable for color printing of small lots and many kinds, can apply multicolor painting-like patterns and complex patterns at low cost, etc. Characteristic can be used for color painting of textiles.

[0007]

Means for Solving the Problems To solve the above-mentioned problems, the present invention provides (1) weaving with a yarn obtained by cutting a sheet-like base material having a surface coated with a coating of crosslinked polyvinyl alcohol having a thickness of 5 μm or more. (2) a yarn obtained by cutting a sheet-like substrate having a coating of a cross-linked polyvinyl alcohol having a thickness of 5 μm or more on the surface thereof, or the same yarn as this; A color painting by an ink jet method was applied to a woven fabric woven using a yarn of a natural material and one of the yarns twisted into a core yarn, or (3) a coating of crosslinked polyvinyl alcohol with a thickness of 5 μm or more. Yarn obtained by cutting a sheet-like base material that has been coated on its surface and color-painted on the coated surface by an ink jet method, or the same yarn as this, is twisted into the core yarn Thread the Ekei and / or Enuki, i.e. both Ekei and Enuki, or devoted to either Ekei or Enuki, characterized in that woven fabric and.

[0008] In these (1), (2) and (3), the sheet-like base material has a texture (strength) of a flat foil (a piece of gold paper or silver foil pasted on a goose paper or a birds child paper with lacquer). Preferably it is equivalent to that. If the texture of the sheet-like base material is not good, otherwise, the usefulness of color painting with good color expression by the ink jet method applied to the fabric is reduced, that is, the commercial value of the obtained design fabric is reduced. .

In the present invention, a yarn obtained by twisting a yarn obtained from a sheet-like substrate having a surface coated with a cross-linked polyvinyl alcohol (hereinafter referred to as yarn A) with a core yarn (hereinafter referred to as yarn B) In the case where the woven fabric is woven in step (1), or when the woven fabric is woven using a combination of any one of the yarn (a) and the yarn (b) and a yarn of a natural material, a coating of crosslinked polyvinyl alcohol is formed on the surface of the woven fabric prior to color painting. This is to avoid color bleeding occurring in the core yarn or the yarn of the natural material when color painting is performed without the latter coating.

In the present invention, a yarn obtained by cutting a sheet-like substrate having a surface coated with a cross-linked polyvinyl alcohol, or a yarn obtained by twisting the same yarn with a core yarn, is used as a picture sutra and / or a picture. When weaving a woven fabric to the weft, the use of yarn may be the same as in the conventional method, and the use of yarn to apply to the drawn foil may be the same as the conventional drawn foil technique.

In the present invention, the cross-linking agent for polyvinyl alcohol is a blocked isocyanate-type polyisocyanate cross-linking agent which regenerates an active isocyanate group by heat treatment, and is Elastron BN- manufactured by Daiichi Kogyo Seiyaku Co., Ltd. in Kyoto City. 08 (product name) as an example.

When this crosslinking agent is added to an aqueous solution of polyvinyl alcohol and heated, the blocking agent is dissociated, the active isocyanate group is regenerated, and a crosslinking reaction occurs with the functional group of polyvinyl alcohol. The required heating is performed after the polyvinyl alcohol aqueous solution to which the crosslinking agent has been added is applied to the sheet-like substrate. The amount of the cross-linking agent added to polyvinyl alcohol is very small, for example, in the case where an aqueous solution of polyvinyl alcohol is blended with an equal amount of water of polyvinyl alcohol stock solution,
It may be 2 to 5% by weight. Prior to color painting, the heating in the case where a crosslinked polyvinyl alcohol coating is formed on the surface of the woven fabric is the same as that described above. The crosslinking agent to be added to polyvinyl alcohol for the latter coating and the amount of the crosslinking agent may be the same as described above.

[0013]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

In the figure, reference numeral 1 denotes a sheet-like base material as a material for yarn for the decorative fabric I according to the present invention.

The sheet-like base material 1 is made of a base material a (made of Japanese paper, silk paper (named a person skilled in the art of Japanese paper made by mixing silk fibers), metallized Japanese paper or metallized silk paper, metalized film, etc.). 1,3,5,6,7,8) or a film or a metallized film on the surface of a substrate a '(FIGS.
It is provided with a coating b of at least 5 μm in thickness of crosslinked polyvinyl alcohol. The film thickness of the coating b is more than 15 μm, which is generally 7-1 to 1.
0 μm. Here, the metallized washi, the metallized silk paper, and the metallized film are a Japanese paper, a silk paper, and a film in which a metal film such as a gold foil or a silver foil-like metal film is formed on the surface by a method known per se. That is.

Regarding the base materials a and a ', the coating b of the crosslinked polyvinyl alcohol may be applied on one side or on both sides. Figures 1, 2,
The base material of 5, 6 was applied to both sides as shown in FIGS.
8 is a substrate.

In order to apply the coating b on the surfaces of the substrates a and a ', a coating material obtained by adding a small amount of a crosslinking agent called Elastron BN-08 (trade name) to an aqueous solution of polyvinyl alcohol is applied to a coater (doctor, roll, Screen) or a specification of coating by a spray method. To this coating material, a minute amount of inorganic fine powder pigment may be added.

When the coating b is applied by using a coater or a spray, if the surface of the substrate is made of Japanese paper or silk paper, a coating material of polyvinyl alcohol to which a crosslinking agent is added is directly applied to the surface of the substrate. A coating with the required adhesive strength is obtained. In the case of metallized Japanese paper, metallized plain silk paper, and film, the required adhesion strength of coating the coating material by a coater or a spray is low, but the application of the required adhesion strength can be achieved by using a primer coat. The application of the coating b may be performed by the following transfer method.

Transfer method: A transfer paper or film in which a crosslinked polyvinyl alcohol coating is formed on a release surface of a release paper or a plastic film, is superimposed on the transfer paper or film so that the crosslinked polyvinyl alcohol coating is on the surface of the sheet-like substrate 1. A method of transferring the coating of the crosslinked polyvinyl alcohol on the transfer paper or film to the surface of the sheet-like substrate 1 by applying pressure under heating. The adhesive required for this transfer is applied on the surface of the transfer paper or film coated with crosslinked polyvinyl alcohol, or on the surface of the sheet-shaped substrate 1.
Since the coating of the crosslinked polyvinyl alcohol is water-soluble, a solvent-type adhesive is preferably used so as not to adversely affect the water-soluble adhesive.

What has been described above is an embodiment common to the present invention according to claims 1 to 3, which relates to a base material as a yarn material for the decorative fabric I.

An embodiment of the present invention according to claims 1 to 3;

The thus obtained yarn (not shown) or a yarn obtained by twisting the same yarn with a core yarn is used to weave a woven fabric. Alternatively, a yarn obtained in the same manner, a yarn obtained by twisting the same yarn with a core yarn and a natural material yarn in combination, that is, the former yarn described here and a natural material yarn are used in combination Alternatively, the fabric is woven by using the former yarn and a yarn obtained by twisting the same yarn with a core yarn.
When the sheet-like substrate 1 is a film or a metallized film, the yarn obtained from the sheet-like substrate is used in order to make the texture of the woven fabric the same as that of a general fabric. Used with natural fiber yarns.

A color painting 2 is applied to the fabric by an ink jet method. Thus, the fabric becomes the design fabric I. Color painting by the ink jet method may be performed according to a method known per se.

A yarn (this yarn is referred to as yarn A1) obtained by twisting a yarn (this yarn is referred to as yarn A1) obtained from a sheet-like substrate having a surface coated with a predetermined thickness of cross-linked polyvinyl alcohol (this yarn is referred to as yarn A2) If weave the woven fabric, or yarn A
1. When a woven fabric is woven by using any of the yarn A2 and a yarn of a natural material (this yarn is referred to as a yarn A3), a coating of crosslinked polyvinyl alcohol is formed on the surface of the woven fabric prior to color painting. The need for this is as described above. The thickness of this latter coating may be of the order of 2-3 μm.

On the surface of the obtained design fabric I, after color painting, a protective coating of a hydrophobic resin such as polyurethane is applied on the surface of the design fabric yarn in order to impart water resistance to the cross-linked polyvinyl alcohol coating. It is preferable to apply a protective coating such as silicon or Teflon. The protective coating may be applied by one or several applications of a coating material.

An embodiment of the present invention according to claim 4; a sheet-like substrate 1 having a surface painted in color by an ink jet method is cut into a width similar to that of a foil thread. The obtained yarn or the yarn obtained by twisting the same yarn with the core yarn is applied to the picture sutra and picture weft or any of the picture sutra or picture weft to weave the fabric. Thus, the fabric becomes the design fabric I.

In the latter embodiment, in order to impart water resistance to the coating of crosslinked polyvinyl alcohol on the yarn obtained from the sheet-like substrate 1 whose surface is colored with an ink jet method, the color applied to the coating is applied. It is preferable to apply a protective coating of a hydrophobic resin such as polyurethane on the painting and then apply a protective coating of silicon, Teflon or the like, or to apply an ultra-thin (2 to 9 μm) film of polyester. The protective coating may be applied by one or several applications of a coating material.

In the present invention according to claims 1 to 3, the yarn for the starting material of the design fabric or the fabric as an intermediate product has a crosslinked polyvinyl alcohol having a thickness of 5 μm on the surface.
Threads obtained by cutting a sheet-like base material with a coating of m or more, or yarns obtained by twisting the same yarns into core yarns, or one of the same yarns as the former two and natural materials Yarns are used together. And, when the woven fabric is woven with a yarn obtained by twisting a core yarn with a yarn obtained from a sheet-like substrate having a surface coated with crosslinked polyvinyl alcohol, or the same yarn as the former yarn in the twisted yarn, When a woven fabric is woven with a combination of one of a yarn obtained by twisting the same yarn with a core yarn and a yarn of a natural material, a coating of crosslinked polyvinyl alcohol is formed on the woven fabric surface prior to color painting.

According to this, when the starting material or the fabric as an intermediate product is color-painted by the ink jet method, a color painting exhibiting a good color without mixing ink particles of different colors is obtained. can get.

This effect is achieved due to the coating of the crosslinked polyvinyl alcohol on the yarns A1, A2, A3. By the way, as described above, when color painting is performed on a general woven fabric by the ink jet method, the appearance of color becomes inferior, and a base material coated with an uncrosslinked polyvinyl alcohol is used. The yarn obtained by cutting also has poor color expression. Even if the coating is crosslinked polyvinyl alcohol, its thickness is 5μ
If it is not more than m, the color painting by the ink jet method applied to the coating does not bleed the ink to obtain a good color.

According to the fourth aspect of the present invention, it is obtained by applying a coating of crosslinked polyvinyl alcohol having a thickness of 5 μm or more to the surface, and cutting a sheet-like substrate having the coating surface colored by an ink jet method. yarn,
Alternatively, the same yarn is twisted to the core yarn, and the yarn is
Or, weave design fabrics for the picture.

The decorative fabric according to the present invention is the same as the decorative fabric according to any one of claims 1 to 3, except that the object to be colored by the ink jet method is a substrate coated with a crosslinked polyvinyl alcohol. The configuration is substantially the same. Therefore, the present invention according to claim 4 also corresponds to claim 1
The same effects as those of the present invention according to (1) to (3) can be obtained.

From the experimental results, it was confirmed that the color painting applied to the woven or sheet-like substrate according to the present invention also had good fixability.

In the present invention, the sheet material is used as the starting material for the decorative fabric or the yarn base for the fabric as an intermediate product, if the yarn base is in the form of a sheet, it is cross-linked. This is because coating of a polyvinyl alcohol coating can be industrially achieved under mass production, and preparation of the coating to a required thickness is easy.
