Description

Dyeing Method of Towel and Its Dyed Towel

The present invention relates to a method of dyeing a towel and a dyed towel, and the pattern and the color of the printed pattern and text printed on the background color by passing through the bleaching process to the portion to be printed before printing the pattern or text on the towel having a background color after the dyeing process It prevents the deterioration of chromaticity and enables precise printing.

In general, the surface of the towel is printed and distributed in a variety of patterns and characters that appeal to people's eyes. Prior to the printing process of printing, such as printing of the pattern of the towel and the character, the printing process has caused a lot of toxic waste water because it uses a large amount of dye ink, unlike the pigment ink used in the printing process has caused environmental pollution. Therefore, in recent years, as environmental standards in Korea have been strengthened, colored towels of towels treated with low-cost dyeing have been imported and used in China. Since these colored badges are already made of a variety of colors or patterns, if a printed pattern or text is printed on the surface of the background as a souvenir or gift, the original color to be produced will not be printed. Or they have the problem of changing to other chromaticity. In addition, if the background color of the towel is dark or dark, it is more difficult to adjust the color and chromaticity of the pattern or the printing, and thus the choice of the color used as the background color is narrow.

Known methods for printing such patterns and texts on the towel are clear and easy to distinguish, but a method of printing a pattern or text by removing the brushed layer of a certain part of the towel is known. If the background color is colored even in the removed state, there is a problem that a change in color and chromaticity is involved.

Therefore, in the present invention, in order to solve the above problems, adding a process of bleaching the same shape or pattern to be printed on the surface of the towel to be printed on the towel having a colored background color, bleaching, bleaching part Printing is performed by printing using normal ink on the inside of the ink, but by adding and using a chemical to prevent the ink from spreading in the ink to prevent the ink from spreading to the adjacent color to produce a fine and clear pattern and letters The purpose is to provide a dyeing method and a dyed towel.

In order to achieve the above object, the present invention, in the dyeing method of the towel consisting of the main dyeing step (10), printing step (30), drying step (40), setting step (50) and drying step (60), Before printing, bleach is applied to the surface of the dye-treated colored medium through a conventional screen printing process for printing a pattern or a character to be printed using a towel of a colored medium having a ground color by the dyeing process (10). Bleaching printing process (20) in which bleaching pattern (70) is formed by bleaching to white by using color, and printing color pattern (80) through screen printing using printing ink that does not spread to the discolored partial adjoining color. By including the printing step 30, it is characterized in that the dyeing method of the towel which can prevent the deterioration of the color due to the overlapping with the background color and can freely adjust the chromaticity.

Hereinafter, the dyeing method of the present invention will be described in detail.

The present invention prevents alteration and chromaticity change due to color overlap in presenting presenter marks, marks or various patterns printed on color towels used for souvenirs or gifts, and prevents ink from spreading to adjacent colors during printing. Precise printing work is possible.

First, in order to design on the surface of the colored paper for towels, which have been treated with a monochromatic color or a single color, a bleaching agent is screen-printed and bleached in the same size and shape as the pattern and character. After such a bleaching printing process, the surface of the colored medium is left with white marks or letters on the surface of the colored medium, and this part is used as the part to be printed during the printing of the next process.

The bleach used in the decolorizing process may be a compound having a reducing action such as zinc powder, sodium formaldehyde sulfoxylate (trade name: Rongalite), Stannous chloride, or an oxidizing action such as chlorate, permanganate, erythritis, and septic salt. Examples are compounds.

After the above bleaching printing, the above bleaching process is carried out by using a mixture of chemicals, Carbol 4089, which can prevent the printed ink from spreading to the adjacent color when printing on an oil-based colored ink used as a general towel printing ink. By preventing the overlapping of the color by the role of enabling precise printing work.

In addition, in the dyeing method of the present invention, the printing of the printing using the bleaching agent in the printing ink for printing the printing so that the bleaching and printing printing at the same time can shorten the work process, and also prevent the overlapping of colors. To perform a function.

Hereinafter, the dyeing process of the present invention with reference to the accompanying drawings in detail.

1 is a flow chart showing the process of the dyeing method of the present invention, the main dyeing process (10), bleaching printing (20), printing process (30), drying process (40), setting process (50) and drying process (60) By going through the process of printing, it is possible to prevent the color and chromaticity change during printing.

The dyeing process (10) is a dyeing method that is widely employed in the method of producing a large amount of dyed fabrics such as banners, scarves or ties, the background color of the towel in the present invention also performs a dyeing, a detailed description thereof will be omitted. do. The dyeing process of the present invention may be adopted by the manufacturer, if necessary, or may be used as a dye-colored towel medium treated with imported dyes.

The bleaching print 20 is performed on the surface of the towel having the background color through the main dyeing process. The bleaching printing process 20 is a feature of the present invention that is not in the ordinary printing printing process, and in this process, the first bleaching agent is printed using bleach instead of ink. The background color is bleached to white, leaving space for the pattern and text to be printed.
