Dyeing expression combining persimmon tannin with two or more other coloring materials

Abstract

To provide a novel dyeing expression combining persimmon tannin with two or more other coloring materials and utilizing various hues and designs.SOLUTION: Screen textile printing is performed on a fabric made from natural fibers using persimmon tannin paste adjusted to a viscosity suitable for textile printing by adding a thickening agent to persimmon tannin, and persimmon tannin color paste, which is prepared by adding various natural pigments and natural dyes to the persimmon tannin paste. Then, the persimmon tannin color paste to which the natural pigments are added, is steamed in saturated vapor at 100 degrees for 60 minutes to promote the condensation of the persimmon tannin and reinforce a coating film applied to the fibers, followed by cleaning to complete the treatment. The persimmon tannin color paste to which the natural dyes are added, is separately blended with mordant paste made by adding various mordant solutions to a paste material with a viscosity suitable for textile printing, and a post-mordant technique is used in such a manner that these are overprinted onto the previously printed persimmon tannin color paste using a draw dyeing technique. After drying, the persimmon tannin color paste is steamed in saturated vapor at 100 degrees for 30 minutes, followed by cleaning to complete the treatment.SELECTED DRAWING: None

Description

Technical Field

[0001] Screen printing is performed using a persimmon tannin color paste prepared by blending persimmon tannin and other color materials with natural fibers. When the color material to be overlaid is a pigment, it is steamed and fixed after drying. When it is a natural dye, post-mordant fixation is performed by overprinting with a mordant paste in the shigoki dyeing method after drying.

Background Art

[0002] Persimmon tannin dyeing using the techniques of dip dyeing and drawing dyeing has been carried out before.

[0003] A method that enables screen printing using various natural dye solutions and mordant solutions simultaneously in a base paste for screen printing developed for natural dye solutions has been confirmed. When a persimmon tannin paste with viscosity was prepared by adding a thickener to persimmon tannin, and a natural dye solution (other than persimmon tannin) was directly added thereto, and then a mordant solution for promoting color development and fixation was added, the paste itself separated and did not meet the screen printing conditions.

Summary of the Invention

Problems to be Solved by the Invention

[0005] Persimmon tannin has long been widely and commonly favored as an essential dye in the broad living cultures of Asia, including Japan. However, in recent years, due to the spread of chemical products, the culture of persimmon tannin dyeing has been on a declining trend. Persimmon tannin tends to be favored by middle-aged and elderly people because of its astringent color, but currently, many young people are unaware of its existence. Traditional persimmon tannin dyeing mainly involves immersion dyeing or brush dyeing, and the image of "persimmon tannin = brown color and astringent texture" has been an established perception. In this invention, to break away from this fixed concept and increase the number of new persimmon tannin enthusiasts, a new image of "persimmon tannin = old and new, astringent and popular (approachable)" is newly updated. While taking persimmon tannin as the mainstay, provide new expression methods that make use of various colors and patterns.

Means for Solving the Problems

[0006] In this invention, "persimmon tannin paste" is made by adding a thickening agent to persimmon tannin to achieve a viscosity suitable for printing, and "persimmon tannin color paste" is prepared by adding various natural pigments / natural dyes to the above-mentioned persimmon tannin paste. The above-mentioned persimmon tannin paste and persimmon tannin color paste are printed on the fabric and dried. After that, the persimmon tannin color paste added with natural pigments is steamed with 100-degree saturated steam for 60 minutes to promote the condensation of kaki tannin and make the film coating the fiber strong, and then washing is carried out to complete the process. For the persimmon tannin color paste added with natural dyes, a "mordant paste" is separately prepared by adding various mordant solutions to a paste material with a viscosity suitable for printing, and they are overprinted on the persimmon tannin color paste previously printed using the technique of "shigoki dyeing". After mordanting, it is steamed with 100-degree saturated steam for 30 minutes, and then washing is carried out to complete the process.

Effects of the Invention

[0007] Conventional dip dyeing and pull dyeing methods using persimmon tannins have been difficult to mass-produce due to the high labor and cost involved for artisans, and have not deviated from the image of "persimmon tannin = brown, astringent texture." The screen printing method for pattern dyeing with persimmon tannins, using the "persimmon tannin color paste" and "striking mordant" of this invention, adds a range of colors to persimmon tannin dyes, which have traditionally only been used in single colors, and enables a wide range of creative expression through pattern dyeing. Furthermore, screen printing makes mass production possible, allowing it to be offered as a new product in various textile industries, and also shows the potential for new dyeing methods using persimmon tannins, a sustainable colorant with low environmental impact. DETAILED DESCRIPTION OF THE INVENTION

[0008] The fabric used is a medium-weight natural cotton oxford. There are six types of persimmon paste used, with those made with natural pigments indicated by lowercase letters and numbers, and those made with natural dyes indicated by uppercase letters and numbers. After printing, the persimmon tannin paste ad, which contains natural pigments, is steamed in saturated steam at 100 degrees for 60 minutes and then washed. After printing the persimmon tannin pastes A and B, which contain natural dyes, mordant pastes 1-3 are layered on top of the persimmon tannin pastes A and B using a stencil for ironing, and then printed.The fabric is then steamed in saturated steam at 100 degrees for 30 minutes and washed. The ingredients used to make persimmon tannin paste and various persimmon tannin color pastes are listed in Table 1, the ingredients used to make various mordant pastes are listed in Table 2, and the names of colors that are similar when the persimmon tannin paste and various persimmon tannin color pastes are completed are listed in Table 3.

Claims

1. Screen printing is performed on a natural fiber product using a persimmon tannin color paste prepared by blending persimmon tannin and other color materials. If the color material is a natural pigment, it is steamed and fixed as it is. If the color material is a natural dye, after drying, a mordant paste prepared by blending a mordant containing metal ions is overprinted by the shigoki dyeing method and post-mordanting is performed. Then, it is steamed with saturated steam at 100 degrees and washed, so that the kaki tannin contained in the persimmon tannin condenses and the fiber is coated, resulting in a texture like a film.
