Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laminated moiré fabric which exhibits an arbitrary moiré pattern excellent in dynamism and can be applied to women's clothing, curtains, bags and the like.

[0002]

2. Description of the Related Art Conventionally, as a method of producing a moiré pattern in a cloth for clothing or living use, a method of performing moiré processing on a cloth alone and a method of using a plurality of cloths in a stacked manner have been generally performed. As a method of expressing the fabric alone,
Generally, a method using printing and calendering is used. Japanese Patent Application Laid-Open No. Sho 59-66584 discloses that a printing method is used to impart a phase difference having a periodicity to the interval between ground structures constituting a fabric. A method for expressing a moiré pattern is described in US Pat.
No. 61 describes a method of expressing a moiré pattern by performing printing using a plurality of screen mesh fabrics.

[0003] Also, Japanese Patent Application Laid-Open No. 2-26982 discloses that
By performing calendering on a woven fabric in which high-density parts and low-density parts are mixed in the warp and weft directions with a metal roll in which a large number of fine wires are engraved in parallel, two or more types in the warp and weft directions are obtained. A method for expressing a moiré pattern is described. However, in the method of processing the cloth alone as described above, the obtained moiré pattern is fixed, and it is not possible to obtain a moiré pattern with various changes and excellent dynamism.

On the other hand, as a method using a plurality of fabrics,
Japanese Unexamined Patent Publication (Kokai) No. 64-20383 discloses a method in which a surface base cloth having a plane porosity of 20% or more and a cloth other than the surface base cloth having a plane porosity of 15% or more are used. A method for obtaining a moiré pattern is described. However, in such a method using a plurality of cloths, when synthetic fibers that are easily charged are used, static electricity is generated, and the cloths cling to each other due to electrification due to friction, and a dynamic movement that is rich in changes due to dynamic movement. There is a problem that a moiré pattern cannot be obtained.

[0005] Further, according to any of the above-mentioned methods, only a monotone pattern can be obtained as a moiré pattern, and a pattern excellent in dynamism cannot be obtained. Even if a plurality of fabrics are superimposed, the resulting design will be moiré fringes, which are accidental moire fringes that appear due to the fabric structure and warp / weft yarn density. It is not possible.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances, and proposes a new method for moiré processing, which tends to be monotonous, so that the resulting moiré pattern is clear and changes. It is an object of the present invention to obtain a superimposed moiré fabric which is rich in varieties and can express an arbitrary pattern by moiré stripes.

[0007]

The present invention attains the above object and has the following constitution. That is, the present invention is a laminated fabric of an antistatic surface base cloth and a lower base cloth, wherein the surface base cloth is a cloth having regularity in at least one direction with a void of 15% or more, The lower base fabric is characterized by a structure that uses the fabric printed in conformity with the regularity of the voids in the front base fabric and changing the hue at the boundary of the pattern, or printing a pattern with the phase of the regularity shifted. The gist of the present invention is that of a moiré fabric.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail. Examples of the fiber cloth used as the surface base cloth and the lower base cloth according to the present invention include polyamide synthetic fibers represented by nylon 6 and nylon 66, polyester synthetic fibers represented by polyethylene terephthalate, polyacrylonitrile synthetic fibers, and polyvinyl alcohol. Synthetic fiber,
Natural fibers such as cotton and silk, semi-synthetic fibers such as triacetate, and woven, knitted and non-woven fabrics using these mixed fibers can be used. As the structure, the surface fabric is preferably a lace-like fabric or a mesh-like knitted fabric in which the pattern of the lower fabric is easily seen through, and the lower fabric is not particularly limited as long as it can be printed, and is not particularly limited. A fabric such as a nonwoven fabric can be used.

In the present invention, in order to impart antistatic properties to the surface base cloth and the lower base cloth, resin processing using a generally known antistatic agent, for example, polyoxyethylene fatty acid ester, polyoxyethylene alkyl ether, etc. Nonionic antistatic agents, anionic antistatic agents such as phosphate esters and sulfates, cationic antistatic agents such as poly-β-methacryloxyethyl, diethylmethylammonium metasulfate, and zwitterionic charging such as betaine imidazoline A known antistatic agent such as an inhibitor can be applied by a generally known resin processing method such as a padding method or a spray method.

In addition, metal powders such as stainless steel, nickel, copper, iron or alloys thereof having excellent conductivity, metal compound particles such as copper sulfide, zinc sulfide, cadmium sulfide, copper iodide, tin oxide, zinc oxide, Conductive fibers containing metal oxide particles such as copper oxide, tungsten oxide, zirconium oxide, and indium oxide in the fibers during the production of the fibers; polyoxyalkylene glycol; block polymers of polyoxyalkylene glycol and polyester; The conductive fiber in which a hydrophilic polymer such as a polyoxyalkylene compound such as a block polymer of an alkylene glycol and a polyamide is mixed into the fiber during the production of the fiber is used alone, or is mixed with the above-mentioned fiber cloth to control electricity. Properties can be imparted.

The regularity of the voids of the surface fabric used in the present invention refers to a state in which the intervals of the voids are 0.5 to 50 per inch and regularly arranged in at least one direction. In the case of general cloth, in the case of a structure having voids, there are usually many regularities in two directions, that is, vertical and horizontal directions. However, the present invention is not limited to this. It may be. The porosity is the total area of the voids with respect to the entire plane of the fabric. The higher the porosity, the more easily the lower fabric design can be seen through when overlapping, so that the number of filaments is small and the transparency is low. It is even more effective to increase the porosity by using a yarn excellent in porosity.
Specifically, the porosity is preferably 15% or more, and more preferably 40% or more, with respect to the entire plane of the fabric.

Next, as a printed pattern applied to the lower base cloth, a pattern synchronized with the gap of the front base cloth is printed and used as a basis for developing moiré stripes. For the printing, a known flat screen printing machine, rotary screen printing machine, and roller printing machine can be used in a usual manner. If the pattern to be tuned here is a stripe-like pattern, it is necessary first to synchronize the directionality, and when the surface base cloth and the lower base cloth are neatly superimposed, the regularity of the voids is reduced. The angle at which the direction intersects the direction of the stripe-like pattern is 0 to 2
Must be in the range of 5 °, preferably 0-10 °
Range is good. If the angle exceeds 25 °, the desired excellent dynamic moiré pattern cannot be obtained. Second, it is desirable that the density of the stripes be the same as the space between the gaps in the surface fabric. However, the difference in the density may be within about ± 10% or one of the combinations may be an integral multiple of the other.

In the case of a polygonal pattern such as a square or a rhombus other than the stripe-like pattern, the angle at which at least one side of the polygon intersects with the direction of the gap of the surface fabric is in the above range (0 to 10).
°, Max 25 °), but it is not limited to a pattern such as a round shape whose side cannot be determined. The width of the pattern and the number of squares may be set in the same range as described above. The moiré pattern developed by such a method is a dynamic pattern, but does not go out of the area of the moiré pattern determined by each structure and yarn density.

In the present invention, based on the print processing by the above-described method, by adopting a printed pattern using a method of changing the hue at the boundary of the pattern or a method of shifting the phase, a dynamic and arbitrary pattern is obtained. The biggest feature is that the pattern is expressed by moiré stripes. As a method of changing the hue in the present invention, a method of setting the hue of a stripe of a pattern portion to be expressed to a color different from that of the surrounding stripes can be adopted, and a combination of a dark color and a light color or a complementary color relationship can be adopted. In terms of contrast, it can be expected as the sharpest moiré fringes. In terms of design, tone down or gradation can also be adopted, and may be appropriately selected according to the pattern to be expressed.

Next, as a method of shifting the phase, when the pattern of the lower base fabric synchronized with the regularity of the surface base fabric is, for example, a striped pattern, the boundary of the triangular pattern as shown in FIG. A method of shifting the phase can be adopted. In other words, it is a method of expressing an arbitrary pattern by distorting a part of the pattern of the monotone stripe to change the moiré stripe. The degree of distortion may be appropriately adjusted according to the pattern to be expressed, but in the case of a stripe pattern, it is appropriate that the repetition period is set to one pitch and the pitch is shifted by 1/10 to 1/2 pitch, that is, distorted. These methods may be used alone, but when used in combination, an arbitrary pattern can be more visually expressed as a moiré pattern that is more varied. The present invention has the above configuration.

[0016]

As in the case of the laminated moire fabric of the present invention, when a surface fabric having at least 15% of voids having regularity in at least one direction and a lower fabric having a printed pattern synchronized with the regularity are superimposed, Due to the interaction between the former void and the latter printed pattern, a visually excellent moiré pattern develops, and if the antistatic property is imparted to each of the surface base fabric and the lower base fabric as in the present invention, the static electricity is reduced. Adverse effects are suppressed,
There is no discharge phenomenon due to adhesion of dust and dust and accumulation of static electricity, no clinging, and a moiré pattern full of dynamism can be developed by free movement.
In addition, by adopting a method of changing the hue or a method of shifting the phase independently or in combination with the print design of the underlying fabric according to the pattern to be expressed by moiré stripes, any pattern can be further changed visually. It can be expressed as a rich moiré pattern.

[0017]

EXAMPLES Next, the present invention will be described more specifically with reference to examples. The evaluation of the performance of the fabric in the examples was performed by the following method. (1) Moiré pattern The moiré pattern generated when the front base cloth and the lower base cloth are superimposed on each other and gently moved assuming movement during wearing is observed with the naked eye, and the following four grades are evaluated relatively. Was done. ◎: Any pattern is clear and appears as a moiré pattern with excellent dynamism. ：: An arbitrary pattern does not appear, but a moiré pattern with excellent dynamism appears. Δ: There is no dynamism, and an unclear moire pattern appears. ×: Moire pattern does not appear at all.

(2) Clinging Cloth (surface base cloth and lower base cloth) according to JIS T-8118
After the charging treatment, the cloth was quickly taken out of the tumbler dryer, and assuming the movement at the time of wearing, the state of superimposing and gently moving was evaluated relative to the following three steps. ◎: The fabric can be moved smoothly without clinging, and a moiré pattern with a clear and dynamic feeling is exhibited. : The cloth stuck together a little due to electrification, making it difficult to move freely, and the moiré pattern lacked a lively feeling. ×: The cloth was not moved due to the electrification, and the moiré pattern did not have a lively feeling.

By the exactly same method as in this example, a comparative laminated moire cloth (Comparative Example 1) having inferior antistatic property was obtained. For comparison with the present invention, in this example, a polyester multifilament 50 denier / 24 filament was used in place of the warp monofilament of the surface base fabric, and a polyester multifilament 50 denier / 24 filament was used instead of the weft monofilament. Except that the warp density was changed to 140 yarns / inch and the weft density was changed to 120 yarns / inch.
By the exactly same method as in this example, a comparative lapping moire cloth (Comparative Example 2) inferior in transparency of the surface base cloth was obtained.

Further, for comparison with the present invention, the two types of wefts used as the surface fabric in this embodiment are replaced with one alternate repeating pattern of two wefts, thereby providing a visual repetition pattern. A cloth having a black fine line width of 0.3 mm, a density of 40 lines / inch, and a porosity of about 27% is used as a surface base cloth.
