* Description of the symbols used in the main parts of the drawings *

1: printing part (configured as a functional agent)

2: vesicle area (with constituent fibers remaining)

The present invention is processed to a pattern designed using functional agents such as chitosan, alginic acid, gelatin, collagen, PVA (polyvinyl acetate), sericin, and acrylic organic compounds in raw cloth, that is, woven, knitted or nonwoven fabrics. And the functional agent is evenly coated only on the fiber of the pattern part,

In other parts, the original characteristics of the constituent fibers remain intact, and when the sun bathing is applied, the functional dye processing monochromatic cloth fabric having a different color from the pattern area and the original fabric area is provided. will be.

Functional dye processing mono-dye pattern cloth is processed with pattern cloth using existing chitosan, alginic acid, gelatin, collagen, PVA, sericin, acrylic, organic and inorganic compounds, and is designed differently from functional processed fabrics. Functional agents such as alginic acid, gelatin, collagen, PVA, sericin, and acrylic organic compounds are applied only to the designated pattern of the original fabric and evenly coated on the fibers of the patterned area, so that a different color pattern is obtained when dyeing in a bath.

This is a multi-layered structure that is distinguished by the area of the fabric, even if the color is not given as in the jacquard fabric, and the patterned area is functional agent such as chitosan, alginic acid, gelatin, collagen, polyvinyl acetate (PVA), sericin, and acrylic organic compound. With the functionality of the raw cloth part will have the characteristics that represent the intrinsic properties of the constituent fibers.

The jacquard fabric is the same textile material and gives only a pattern by different tissues.However, in mono-dyed bicolor fabrics made of chitosan, alginic acid, gelatin, collagen, PVA, sericin, and acrylic organic compounds, chitosan, alginic acid, gelatin, The use of collagen, PVA, sericin, acrylic organic compounds, and the like, to impart a pattern, at the same time to provide functionality and visualize the functionality to have a multi-structure breakthrough technology is required.

Raw cloth is a material widely used in daily life and is obtained in the form of woven fabrics, knitted fabrics and nonwoven fabrics according to the manufacturing process.

These fabrics consist of natural fibers such as cotton, hemp, wool, silk, and cashmere, and artificial fibers such as nylon, polyester, acrylic, and rayon, and mixed fibers thereof. It is required to impart aesthetics with practicality by imposing and coloring.

In particular, jacquard fabrics have a characteristic of displaying a pattern on the fabric without imparting color, and are used as high-quality materials for clothing and daily necessities as a patterned fabric.

Recently, the unique properties of chitosan, alginic acid, gelatin, collagen, PVA, sericin, acrylic organic compounds, etc. are known, and efforts are being made to utilize them in daily life.

One way is to develop fibers and apply them to areas that come into contact with the skin and use them to show antibacterial and biocompatible functions.

In addition, research on applying chitosan to dyeing or processing processes that can easily impart functionality has been conducted in various fields. According to Japanese Patent No. JP10138628A2, when an organic or inorganic acid salt of chitosan or chitosan is added to an ink, When applying color with inkjet method, it can introduce the effect of no discoloration of color without deterioration of physical properties.

According to Japanese Patent No. JP188063A2, when a mixture of alumina hydrolyzate and chitosan is used as a pretreatment liquid for imparting color, excellent water repellency, improvement in dyeing speed, and improvement in dye absorption can be obtained.

In addition, according to Japanese Patent No. JP5169789A2, a highly uniform dye can be obtained by treating the surface of a material to be dyed with a cationic dye and chitosan or chitosan.

All of these are incidental additions to the process of applying chitosan prior to dyeing to improve the quality of the dye. This is just a technique of applying a small amount of chitosan to improve dyeability.

In addition, Japanese Patent No. JP9123339A2 shows that when imposing a mixture of gelatin, collagen, casein or chitosan on the sheet, excellent water absorption and release effects can be obtained.

Korean Patent Application No. 1996-046306 proposes a sanitary processing agent using chitosan alone or a natural metal compound and its processing method.

As described above, it is known that clothes, fabrics, sheets, and fibers containing chitosan may exhibit biological and hygiene functions similar to those of chitosan. To this end, it has been suggested to manufacture and use materials such as chitosan fibers, cellulose fiber-chitosan composites, and fabrics in which resins containing chitosan are processed.

However, all of them are simply processing chitosan by using a small amount on the surface of the fabric, and presenting a product in which a small amount of chitosan is applied, which cannot be given a pattern, while technically giving chitosan, alginic acid, gelatin , Collagen, PVA, sericin, acryl-based organic compounds, such as dyeing and dyeing dyeing (one bath two-tone pattern cloth) does not provide any technology.

In the present invention, by providing sufficient affinity to bind the pores and chitosan, alginic acid, gelatin, collagen, PVA, sericin, acrylic organic compounds and the like only in the predetermined pattern of the original fabric, the patterned site chitosan, alginic acid, gelatin, collagen, PVA, sericin, It provides functions such as acrylic organic compounds and provides a multi-functional functional cloth that shows the unique characteristics of the constituent fibers.
It forms the pattern designed through the technology to give the condition selection and binding of the processing process by manufacturing functional agents such as chitosan, alginic acid, gelatin, collagen, PVA, sericin, acrylic organic compound on the raw fabric and processing conditions. By uniformly coating the functional agent only on the constituent fibers, the functional processed patterned cloth can be obtained only in the required area of the fabric.
The main object of the present invention is a pure chitosan, alginic acid, gelatin, collagen, PVA, sericin, acrylic organic compounds, etc. are applied to the designated area is designed to form a pattern designed and chitosan, alginic acid, gelatin, collagen, PVA, sericin , Acrylic organic compounds and the like are exhibited, and the original fabric part exhibits intrinsic properties of constituent fibers and relates to a dichroic cloth fabric and a mono-dyed bicolor fabric of a multi-structure obtained by dyeing in one bath during dyeing.
The present invention also uses a multi-structured cloth, that is, chitosan, alginic acid, gelatin, collagen, PVA, sericin, acrylic organic compounds, etc., are bound to the desired patterned area, and the fabric part has unique characteristics of the fabric, and is used for one-bath dyeing. It is to provide a bicolor pattern cloth.

Since neutral salts are more soluble in water than dyes, they push the dye out of the water, allowing the dye to adsorb fiber and chitosan, alginic acid, gelatin, collagen, PVA, sericin, and acrylic organic compounds. In this state, the weak alkali reacts with the hydroxyl group of the functional agent and the functional group of the reactive dye to form a covalent bond between the reactive dye and the fiber.

That is, the ionic bond, the fiber, and the functional agent are covalently bonded to the cationic agent in which the reaction island dye is covalently bonded to the fiber and the functional agent. As the neutral salt, Na 2 SO 4 and NaHCO 3 weak alkali are preferably soda ash (Na 2 CO 3).
