Description

Patterned fabrics printed with chitosan {Patterned fabrics printed with chitosan}

The present invention relates to a chitosan printing pattern cloth in which a chitosan is uniformly coated on only a fiber of a patterned part, and the general properties of the constituent fibers remain intact by printing and fixing the chitosan on a fabric, a fabric, a knitted fabric or a nonwoven fabric. will be.

The chitosan printed cloth is a groundbreaking design, unlike traditional chitosan-treated fabrics. Because chitosan is applied only to a designated pattern of cloth and is evenly coated on the fiber of the pattern, it does not give color like jacquard fabric. If not, the multiple structure, which is distinguished by the fabric parts, that is, the chitosan pattern part has the characteristics of chitosan, and the original fabric part has the characteristics of the constituent fibers as they are.

Jacquard fabrics are the same textile material and are given only patterns by different tissues. However, in chitosan printing cloth fabrics, there is a need for breakthrough technology to impart functionality using chitosan and to provide functionality and to have multiple structures.

Chitosan is a substance that can be obtained abundantly from nature and can be widely supplied as a commodity. Chitosan is obtained by deacetylating chitin present in nature. Chitin is a natural substance present in the shells of crabs, shrimps, crayfish, cuttlefish, insects, etc., and is obtained from poly (N-acetyl-D-glucosamine), a natural polymer. Chitin is poorly soluble in water and most solvents, and it is difficult to obtain a solution for preparing fibers, films, and the like.

According to US Pat. No. 3,533,940, chitosan may be prepared from chitin, and chitosan may be dissolved in an organic acid aqueous solution such as acetic acid to form a solution capable of forming fibers, films, and the like.

Chitosan is known to be biotoxic because it is non-toxic and biodegradable, and has biological properties such as cell binding and biotissue culture, antimicrobial activity, hemostatic action, and biocompatibility.

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. The fabric is composed 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. Where fabrics are used in everyday life, it is imperative to impart patterns and colors to impart practicality and aesthetics. 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, as the unique properties of chitin and chitosan are known, efforts are being made to utilize them in human 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.

U.S. Patent No. 4,029,727 explains that chitin can be dissolved in anhydrous organic solvent to produce relatively high strength fibers or films. Here, trichloroacetic acid or the like is used as an organic solvent, so that chitin is easily dissolved, but it is difficult to be widely used in consideration of environmental problems. U.S. Patent No. 4,699,135 discloses chitin fibers by dissolving chitin in polar organic solvents such as dimethylacetamide containing lithium chloride, and also provides chitosan fibers obtained from chitosan solutions dissolved in acetic acid aqueous solution.

On the other hand, US Patent No. 5,900,479 discloses a method for producing an insoluble chitin film, filament and fibers using a chitosan solution in which chitosan is dissolved in an aqueous organic acid solution.

As described above, a lot of techniques related to chitin fiber or chitosan fiber manufactured by using chitin or chitosan as raw materials have been disclosed, and it is possible to make products having biological and hygienic properties using chitin fiber or chitosan fiber. It is open to the public.

In Hasegawa et al. (J. Appl. Polym. Sci., Vol. 45, 1837-1879, 1992), cellulose and chitosan can be dissolved in trifluoroacetic acid to obtain a solution from which a brand film of cellulose and chitosan can be prepared. Let me know. According to Hirano (Biotechnol. Ann. Rev., Vol. 2, 237-258, 1996), chitosan-coated synthetic fiber as well as woven fabric made of chitin fiber and cellulose and chitin composite fibers are not only wettable, It is known that the function appears.

U.S. Patent No. 5,114,788 suggests that cotton fabrics can be immersed in a synthetic resin solution containing chitosan to prepare absorbent fabrics. In addition, US Pat. No. 5,306,550 shows that a biodegradable composite can be made by mixing an aqueous solution of cellulose fiber, chitosan, and a thermoplastic resin.

Recently, various studies have been conducted to apply chitosan to a dyeing process or a processing process that can easily impart functionality. According to Japanese Patent JP10138628A2, when an organic acid salt or an inorganic acid salt of chitosan or chitosan is added to an ink, the inkjet method is used. It is introduced that color can be effected without discoloration without impairing physical properties when imparting color. According to Japanese Patent No. JP188063A2, excellent water repellency is used when a mixture of alumina hydrolyzate and chitosan is used as a pretreatment liquid to impart color. It is reported that the results can be obtained to improve the dyeing speed, and to increase the amount of dye adsorption. 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 using a small amount on the surface of the fabric and presenting products that apply a small amount of chitosan that cannot be patterned. Has not provided.
