Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for printing a fabric, which is characterized in that a pattern that is synchronized with the weaving structure is obtained simultaneously with weaving.

Conventionally, the methods for expressing patterns on fabrics are based on one weaving method, in which yarn-dyed yarns of different hues are arbitrarily interlaced in the warp and weft using a loom equipped with a dobby device, a jacquard device, etc. A method of expressing a pattern by combining weaving structures, a method of expressing an arbitrary pattern on the fabric by a two-print printing method, and a method of expressing the pattern by fixing the dye using a direct printing method or a transfer printing method, and a method of combining 1 and 2. A special method is the 3-way printing method, in which the warp threads are first warped, then put on a loom to create temporary weaving (or under-weaving) in which the weft threads are inserted roughly, and then a pattern is applied to this fabric. A generally known method is to further wind the fabric onto a warp-wound roll, run it again on the loom, and weave the fabric by loosening the loosely woven wefts during provisional weaving while passing new wefts through.

However, in method 1, since the pattern is expressed using a woven structure, there is a limit to its expressive ability, and the processing cost is also high because it is necessary to prepare yarn-dyed threads of different hues.

In method 2, since printing is performed on fabric, it is difficult to synchronize the thread and pattern, making it difficult to create a yarn-dyed feel.

Furthermore, method 3 requires complicated steps and is prone to various troubles, requires high-grade processing technology, and also increases processing costs.

The present invention not only simplifies the process for producing warp-dyed printed fabrics, but also skillfully combines it with dobby machines, jacquard machines, etc. to create yarn-dyed textures that cannot be obtained with conventional printing methods. A very novel method and apparatus for use in this method is provided for obtaining synchronized patterns.

That is, in the present invention, a dye liquid is ejected from a dye liquid ejection nozzle having a fine hole diameter by pressure action, electric field action, magnetic field action, etc., and the amount or flight direction of the ejected dye liquid is controlled according to a signal synchronized with the fabric structure. This is a printing method characterized by warp printing at the same time as weaving, and the equipment used is a loom, a device that gives a signal synchronized to the fabric structure, a pressure action, an electric field action, a magnetic field action, etc. It consists of a dye liquid jetting nozzle that spouts out, and a device that controls the amount or flight direction of the dye liquid jetted out according to the above-mentioned signals.

The purpose of this control device is essentially to apply an appropriate amount of dye liquid to the part of the warp yarn to be dyed, and the dye liquid is spouted out by changing the pressure or electric field applied to the dye liquid jetting nozzle. A method of controlling the amount of charge applied to the dye liquor by installing a charged plate and a deflection plate in front of the spouted dye liquor, and a method of controlling the amount of electric charge given to the dye liquor by the charged plate, and a method of intermittently applying an air flow to the spouted dye liquor. Examples include a method of controlling the flying direction of the dye solution.

Preferably, the loom has a dobby device, a jacquard device, or the like.

Next, a mechanism of an embodiment of the present invention will be explained with reference to the drawings.

FIG. 1 is an explanatory diagram for explaining the present invention in detail.

■ and ■ indicate two warp threads that have been warped in advance and are next to each other.■ and ■ are the threads that move each warp up and down. Each thread is threaded through the hole (■), and a weight (■) is attached to the bottom end of each thread.

■ indicates the reed, and ■ indicates the woven cloth part.

In the figure, the warp thread (■) is pulled up by the thread (2), and the adjacent warp (2) remains at a lower position because the thread (2) is not pulled up.

Therefore, an opening ``■'' shown by a dotted line is formed between ``■'' and ``■''.

There, the weft yarn is passed through the opening marked with ■, pressed against the position marked with ■ by the reed marked with ■, and a normal cloth is woven by repeating this operation alternately.

Next, 0~[phase] is a device that prints the dye liquid on the warp threads,
[F] is input signal converter, 0 is charging plate, ■ is oscillator, 0
is the ink injection nozzle, 0 is the vibrator, [phase] is the pump, [
[phase] indicates an ink tank, O indicates a high voltage power supply, [phase] indicates a deflection plate, ■ indicates a shielding plate, and ■ and ■ indicate ink droplets.

In other words, the threads of ■ and ■ are provided with a mounting frame in the dobby machine and holes in the pattern paper in the jacquard machine, depending on the pattern, and the upper and lower positions are determined by the presence or absence of these mounting frames or the holes in the pattern paper. However, when the thread of ■ is pulled up, the signal is input to ■ as an input @, @, Q, [phase],
The droplets continuously ejected by [phase] are charged by the charging plate (■), and are deflected when passing through the deflection plate of [phase].
It is printed on the warp threads of [phase] without hitting the shielding plate (①).

In addition, if the thread is not pulled up, that is, if it is below the weft thread, the input signal becomes zero, so the droplet is not charged and therefore hits the zero shielding plate without being deflected, and the ink of [phase] It is collected in a tank and recycled.

That is, the droplets are printed on the warp only when the warp is above the weft.

Therefore, by installing injection nozzles corresponding to the number of warp threads, printing is performed only when each warp thread is pulled up by thread threading, so warp printing corresponding to a complex weave structure can be performed at the same time as weaving.

Although the figure shows an example in which a charging plate and a deflection plate are used, it goes without saying that the present invention is not limited to this.

FIG. 2 is a plan view of a printed cloth for explaining an example in which the present invention is applied to a 2/2 twill weave.

The area where the warp is above the weft is indicated by diagonal lines.

By appropriately utilizing the present invention, only the shaded area can be printed at the same time as weaving.

Multicolored patterns and complex patterns can be created by preparing colored spray nozzles or multiple spray nozzles.

[Example 1] Using the apparatus shown in FIG. 1, warp printing was carried out simultaneously with weaving under the following conditions.

Warp: Polyester filament 150 d/
30 f Weft: Same top weave structure; 10/10 twill Weaving speed: 0.5 m/min Drying conditions: 100°C Nozzle diameter: 80 μ Oscillation frequency: 75 KH2 Charging voltage: 80 V Deflection voltage: 500 V Dye liquid prescription Afterwards, the woven fabric was high-pressure steamed at 130℃ for 20 minutes.
After washing and finishing, an extremely good printed cloth was obtained.

[Example 2] Using the apparatus shown in FIG. 1, warp printing was carried out simultaneously with weaving under the following conditions.

Warp: No. 100 double-thread cashmilon yarn (manufactured by Mukasei Co., Ltd.) Weft: Same weave structure: 12-ply satin weave Weaving speed: 0.5 m/min Drying conditions: 100°C Nozzle diameter: 80μ Oscillation frequency; 75 KH2 Charging voltage; 80■ Deflection voltage; 500V Dyeing solution formulation; After that, the woven fabric was steamed at normal pressure at 100°C for 20 minutes.
When the cloth was washed with water, an extremely good printed cloth was obtained.
