Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a method for producing color cards made of fiber cloth in a short time, efficiently, and with high quality.

(Prior Art) The most popular color cards are those made of paper or fiber. When creating them, the former are usually colored by printing, cut to the required size, arranged based on color engineering, and then marked with color names or numbers for arrangement.

In the latter, each color is colored by dyeing, and is treated in the same manner as the former.

However, in color matching using color cards of this type, it is easiest to judge when the two are of the same species, and it is difficult to judge when the two are of the same species. It is desired that color cards be made as close as possible to the same material as the intended product, but in reality, methods other than paper printing require a lot of time and expense. Therefore, it is necessary to substitute existing paper color cards or use fiber color cards, which have many missing colors.

(Problems to be Solved by the Invention) The purpose of the present invention is to solve the drawbacks of the prior art in the production of textile color cards, and in particular to simplify the operation,
To provide a method for producing high-quality color cards in a short time and at low cost.

(Means for Solving the Problem) The present invention prepares a fiber fabric that can be cut into a large number of small pieces, stores coloring conditions in a storage medium, and performs an inkjet coloring process based on the stored information to produce pieces corresponding to the above-mentioned small pieces. Creation of a color card characterized by coloring the desired hue at the ridge points, then successively performing finishing treatments including fixing treatment by dry heat or wet heat, washing and drying, and finally cutting into small pieces. It is the law.

More specifically, the unit processes from the storage process to the cutting process are installed in one device, and each process is performed sequentially in conjunction with the speed of the inkjet process, and 2.4 m2 is completed in at least 60 minutes after the color scheme is decided. This enables the above creation.

The process of the present invention can be illustrated as follows.

In the present invention, this is performed continuously within the same device.

Among the various processes in the present invention, the speed of inkjet printing is the slowest, and this is the rate-determining stage, and other processing conditions are set to adapt to this.

Each dye is dispersed.

-12- It is considered to be a dye, but there are different types of dyes regardless of the type of material.

These dyes and pigments are used as inkjet inks, and the purity of the pigments must first be improved by removing by-products, impurities, additives, etc.
Next, the particle size, viscosity, surface tension, specific conductivity, pH, etc. are adjusted by known methods before use.

The present invention will be explained with reference to the following Examples, but it goes without saying that the present invention is not limited to these Examples.

(Example) First, as the object to be treated, a cotton broadcloth (120cm x 50yx) before dyeing that has been treated by a known method is selected.
A sizing bath solution containing alkali to promote adhesion is applied to this, dried, rolled into a roll, and set in front of an inkjet printing mechanism.

Four ink pots are prepared, the first contains a yellow component, the second contains a blue component, the third contains a red component, and the fourth contains a reactive dye containing a black component. Load the conditioned colorant. When each ink pot is inkjetted with 16 jet dots, each hue is Munsell dye blue, yellow is 7.5Y 3.0/8, and the blue component is 2.5B.
The hue is 4.0/7, the red component is 5R 4.0/10, and the black component is 5G 4.0/20.

The 27 hues obtained by blending these four components are printed in advance and input into a computer according to the determined printing prescription.

Input was performed as follows.

Imprinting 3. 5 cm, length 3.8 cm, left ear part, 90
．． 5crn 1st ribbon band 1st, 2nd, 4th
From the ink, jet 16 dots, 16 dots, 4 dots, then 0.3 cm apart, and then jet the second rib/dot.
8 RBIs, 16 RBIs, 4 RBIs from the 1st, 3rd, and 4th ink.
Jet at RBI.

Thereafter, 27 ribbon bands are printed using the four ink compositions according to the hue instructions.

A cotton fabric as the object to be treated was fixed onto the cylinder via an adhesive applied to the cylinder, and its tip was set under the printing nozzle.

The printing was performed at a printing distance of 2.8 m, a printing voltage of 100 V, and a printing speed of 0.08 m2/min.

The processes below the drying zone were designed to allow a predetermined stagnation time in each process to meet the conditions for cotton broadcloth.

The drying zone is 130°C 740aac, the fixing zone is saturated steam 103°C x 5 min, and the washing is 2 tanks and the first tank contains an anionic surfactant at 80°C
l gin, the second tank is cultivated at 70°C x 1 mi
Next, the second tank was used as a water washing tank, and the first and second tanks were washed with water while overflowing, and the drying zone was under the same conditions as the first.

For cutting, use a knife cutter and printing cloth 3. Ocrn
The paper was fixed at the position where it was to be cut to width, and then it was cut or the paper was set on the edge of the Bon Tei winder.

The fabrics prepared for printing as described above are green, red,
．． ．． ．． A ribbon band that can be used as a color card was obtained, which was given 27 predetermined hues.

(Effects) The advantage of the present invention is that everything from color planning to color card ribbons can be almost automatically carried out by one person. In particular, when it comes to color planning, conventional color cards are composed of 1,000 to 3,000 colors, but the present invention has a super multi-color composition of 6,000 to 40,000 colors. It has become possible to eliminate the inconvenience caused by color.
