Description

Method for dyeing a fiber using a roller

The present invention relates to a method for printing fibers using a roller, and more specifically, using a roller that has undergone a secondary etching process using two kinds of polyethylene films capable of expressing color rendering and dark colors on the dye (fiber). The present invention relates to a printing method using a roller that can form a natural pattern such as a hand spray printing method and can compensate for a disadvantage of the hand spray printing method.

Printing is a kind of dyeing in a broad sense. It is a processing method in which dyes or pigments are uniformly sprayed onto viscous liquids to dissolve them, and the paints are partially inlaid on dough or toners using rollers to display patterns having various colors.

The printing process of the fiber dyes the whole fiber, but gives a variety of color patterns only to the design site, so it can give a variety of changes according to the trend of fashion and is suitable for small quantities of various varieties.

Based on the technique of expressing the shape in printing, there are methods of direct printing, printing printing, and printing printing.In the center of the equipment used, manual and automatic screen printing using a screen printing machine and the intaglio pattern on the roller of the material Roller printing is used a lot.

However, the roller printing method was limited in the shape of the printing pattern, and in particular, the monolithic model could not escape from the situation of the reliability of the product was low. In order to escape the monotony of the printing pattern resulting from the roller printing method, a hand spray printing method has been provided in which a person prints a pattern on fabric paper using a spray gun. However, such a hand spray printing method requires a large number of dyes to be processed by humans in order, so that mass production is not possible due to excessive demand for work time, and a large number of workers are needed to increase productivity. As a result, it has been a factor in excessive expenditure and cost increase of labor costs. In addition, the hand spray method has a disadvantage in that it is impossible to manufacture a repeated pattern shape in a predetermined pattern, and furthermore, it has been pointed out as a cause of defective products because the adjustment of color concentration is not provided uniformly.

In order to solve this disadvantage, Korean Patent Application No. 82-5157 proposes an automatic sprayer type technique for printing by arranging a plurality of spray guns in a row and moving them left and right. Continuous mass production is possible, but the printing pattern itself is not only a continuous monotonous stripe expression, but it is impossible to manufacture a printing textile paper having various printing patterns. In addition, in Korean Utility Model Publication No. 95-27637, it is possible to guarantee the fixing of printing dyes and the surface tension is reduced, so that the printed materials are bonded in a printing shape in a continuous printing station, so that there are no dye spots and the risk of wet dyes. Disclosed are a multicolor printing method and a printing device for obtaining a high quality printing without the ink. This also has the disadvantage that the process is complicated and the apparatus is expensive.

Therefore, in the present invention, by using two kinds of polyethylene films capable of expressing color rendering and dark colors on the stain, a natural pattern such as a hand spray printing method can be formed by using a roller that has undergone a secondary etching process. The shortcomings could be compensated for and the present invention was completed based on this.

Therefore, the object of the present invention is to mass production by reducing the working time according to the continuous work, does not require a large number of working people, and also it is possible to form and manufacture a repeating pattern in a predetermined pattern, moreover the color density To provide a method for printing fibers using a roller that can be provided with a constant control of.

The printing method of the present invention for achieving the above object comprises the steps of providing a first polyester film printed with a dot pattern represented in dark color on the stain (fiber) in the printing method of the fiber using a roller; Providing a second polyester film printed with a dot pattern expressed in color rendering on the dye (fiber); Placing the first polyester film on a roller, irradiating ultraviolet light on the polyester film located on the screen, firstly exposing and firstly etching; Placing the second polyester film on a primary etched roller, irradiating with ultraviolet light on a polyester film located on the screen, secondary exposure, secondary etching, and polishing and plating; And applying a dye on the first and second etched rollers to inlay the dye (fiber).

Looking at the present invention in more detail as follows.

Generally, rollers are used to apply a binder or a foil to the dye (fiber). Such a roller stores a texture source file (also called a texture source image) using a keyboard in a directory of a computer central processing unit (CPU) and recalls a pattern to be printed on the surface of the monitor using a graphic tool. The pattern drawn on the monitor or already drawn is input to the CPU by using the scanner. The texture input file stored in the CPU directory is applied to the pattern input to the CPU to convert it into a dot pattern, and the dot pattern is converted into a polyester film. A polyester film printed on the sheet, and a dot pattern printed thereon is placed on a roller, and the polyester film placed on the roller is irradiated with ultraviolet light to be exposed, and manufactured by etching, polishing and plating.

The CPU of the computer controls the overall operation, and various commands of the user are inputted to the CPU by a scanner, a keyboard, a mouse, and a digitizer, and the user's commands input by them are displayed by the monitor (display). At the same time, the printer is configured to print a screen (eg, a character (letter), a pattern, or a picture) displayed on the monitor.

The texture source file is stored in the directory of the CPU. This texture source file is a reference file for expressing the gradation shade of a pattern (or a character, a picture, etc., hereinafter abbreviated as a pattern) for printing on a roller. The roller printing process using the texture source file having the halftone structure as described above is as follows.

The scanner inputs a pattern to be printed on the CPU, and the keyboard inputs a user's command to print a pattern representing the pattern to be printed in dotted dots, and at the same time, the command regarding the color tone, shade gradation or the position of the pattern. The mouse is inputted to the CPU, and the mouse inputs a user's command together with the keyboard, and is displayed in a menu table of documents, edits, inputs, shapes, tools, templates, tables, the Internet, windows, views, and help. A command is input to the CPU, and the digitizer adjusts a shadow gradation and a hue gradation using a pen pressure, and inputs a command to the CPU about a pattern to be printed.

When a printer, a keyboard, a mouse, and a digitizer input various commands of the user to the CPU, the printer prints the commands input to the CPU on a paper sheet or a polyester film. More specifically, first, texture source files are stored in the CPU directory using the keyboard, and the graphic tool (the graphic tool strongly presses the pen pressure (pressure on the graphic tool) to draw a pattern) displays the screen of the monitor. A black pattern appears on the screen, and the pressure is lightly pressed to draw a pattern, and a light pattern appears on the screen of the monitor). The pattern to be printed on the surface of the monitor is drawn on the monitor and stored in the CPU.

According to the present invention, a texture source file stored in a directory of a CPU is applied to a pattern drawn on a monitor to convert it into a dot pattern, and the dot pattern is printed on the polyester film as described above. At this time, the first polyester film printed with the dot pattern represented by the dark color on the dye (fiber) and the second polyester film printed with the dot pattern represented by the color rendering on the dye (fiber) are separately prepared. This same pattern can be obtained in a subsequent process by preparing two separate polyester films so as to represent the dark color (pattern) and the color rendering (background color) on the stain (fiber) through computer graphics.

Then, the first polyester film is placed on a roller, the ultraviolet film is irradiated on the polyester film to the first exposure and the first etching, and then the second polyester film is placed on the first etched roller. It is positioned, secondly exposed to ultraviolet light on the polyester film, secondly etched, and then polished and plated. When printing using a roller that has been corroded in two different concentrations, the same effect as the hand spray printing effect can be obtained. In other words, the embossed or part of the embossed portion after etching exhibits a cloth color or a light background color, which can give a visual aesthetic, while the engraved portion exhibits a dark color, resulting in a hand spray effect.

Then, the dye is applied to the roller prepared through the above process, inlaid on the chlorine (fiber), and then the chlorine is heated by heating steam at 120 to 130 ° C. to fix the dye to the chlorine. Washing, washing and tenta processing.

The printing method of the present invention including such a process can be mass-produced by reducing the working time according to the continuous work, does not require a large number of working people, and can also form and manufacture a repeating pattern in a predetermined pattern Furthermore, the adjustment of the color density can provide a constant. In addition, the method of the present invention is an environmentally friendly method by significantly reducing the amount of waste water according to the cleaning process compared to the conventional spray printing method.
