Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a discharge agent and a method for processing a synthetic fiber material.

[0002]

2. Description of the Related Art Conventionally, a fiber material composed of a composite fiber obtained by blending, mixing, or knitting and mixing different kinds of fibers such as polyester fiber and cotton, rayon, silk, and acetate, using a disinfectant. The process of partially removing one of the above and forming a watermark pattern is known as an opal process, but in this process, the same color is not obtained between different kinds of fibers, the dye is discolored by a disinfectant, There are problems such as that the printed pattern does not match the exuded pattern and that the cost is high.

[0003] Further, in the process of removing the polyester fiber, an amine and an alkali metal hydroxide are printed and adhered to a cloth made of a modified polyester fiber and an unmodified polyester fiber, and then heat-treated. There is also known a method of forming a watermark pattern by embrittlement and erosion of a modified polyester. However, the method using an amine causes an odor and smoke during the heat treatment and is an environmental problem, and the method using an alkali metal hydroxide has a risk that even the unmodified polyester fiber, which should be originally left, becomes brittle. This causes a problem such as a decrease in the strength of the fabric.
Further, when a dye is contained in the printing paste, and when dyeing the polyester fiber of the printing part, the dye is contained in the printing paste using a conventional amine, alkali metal hydroxide or the like as a disinfectant. Is discolored, and a satisfactory hue cannot be obtained.

Further, in the above-mentioned conventional method, the exfoliating color paste to be printed is often dangerous, and particularly when amines or alkali metal hydroxides are used for the exfoliating color paste, it is difficult to perform the operation. Special care must be taken when doing so.

[0005]

According to the present invention, it is possible to obtain a synthetic fiber material which has been exfoliated without using dangerous substances such as amines and alkali metal hydroxides as exfoliants. It has a very sharp openwork pattern on the edge of the mold or a very sharp uneven pattern on the brushed product, without discoloration of the dye in the printing paste, forming a pattern with a clear hue, and excellent design It is an object of the present invention to provide a disinfectant and a disinfecting method capable of extremely safely producing a synthetic fiber material.

[0006]

Means for Solving the Problems As a result of intensive studies to solve the above problems, the present inventors have found that the conventional problems can be eliminated by using guanidine carbonate as a disinfectant component. Based on the above, the present invention has been completed. That is, the present invention provides a desiccant for a synthetic fiber material containing guanidine carbonate, and a method for processing a synthetic fiber material using a disinfectant containing guanidine carbonate.

Examples of the disinfectant include guanidine carbonate itself, an aqueous solution of guanidine carbonate, and a solution dissolved in a paste. And the like,
By mixing this disinfectant with the original paste, a printing paste can be obtained. The compounding amount may be appropriately selected depending on the type of the synthetic fiber material to be extracted and the target degree of extraction, and is not particularly limited. It is sufficient if it is contained in an amount of 0.5 to 50% by weight, preferably 1 to 40% by weight.

The disinfectant of the present invention is usually used after being adjusted to the form of a printing paste mixed with the original paste. The base paste for adjusting the printing paste is not particularly limited, and the base paste used for various various printing pastes can be appropriately selected and used. For example, natural pastes such as starch, gum arabic, crystal gum, tamarind, sodium alginate, carboxymethyl cellulose soda, propoxycellulose, alginates, guar gum ethylene oxide adducts, ethyl cellulose, methyl cellulose, processed gums such as British gum , Polyacrylates, polyacrylic acid derivatives, polyvinyl acetate, acrylate-vinyl acetate copolymers, polyvinyl alcohol, polyvinyl butyral, polyurethane, polymaleic acid copolymer salts, nonionic surfactants and other synthetic pastes And various types of pastes such as synthetic resin emulsions, diatomaceous earth, and inorganic pastes such as silicate colloids, each alone or as a mixture of two or more, are used as pastes and added to water or an organic solvent to form a solution. Or a dispersion, And those with mucus emulsion of petroleum-based solvent, such as a mixture of the two parties, can be used in the form which has been conventionally used.

[0009] In addition to the disinfectant of the present invention, an adsorbent, a discharge agent, a surfactant, a pigment,
Dyes, anti-reducing agents, sequestering agents, extenders, hygroscopic agents, penetrants, electrolytes, fats, fluorescent brighteners, preservatives, ultraviolet absorbers, antioxidants, etc. be able to. Any dye can be used as the dye that can be blended, and particularly preferably, a quinone-based or quinophthalone-based disperse dye or a reactive dye that can withstand alkali is used.

Printing of the printing paste on the fabric can be performed by any conventional method, and printing can be performed arbitrarily from partial printing of a pattern or the like to printing of almost the entire surface. . Further, the printing may be performed by partially overlapping another printing section. Next, after preliminary drying as necessary, dry heat or wet heat treatment is performed. The method for performing these treatments is not particularly limited, and, for example, as a dry heat treatment method, a method of performing baking using an oven or a dryer, a method of performing baking using a hot press machine, and the like can be adopted. As the wet heat treatment method, a method of performing steaming using an HT steamer or the like can be employed. The treatment conditions vary depending on the type of the synthetic fiber material to be treated, and cannot be unconditionally determined. However, it is preferable to perform the treatment at a temperature of about 90 to 200 ° C. for about 30 seconds to 30 minutes in any method. The effect can be obtained. Thereafter, if necessary, the processing material is subjected to post-processing such as water washing and soaping, and dried.

Of course, the synthetic fiber material subjected to the etching process according to the present invention can be subjected to ordinary dyeing or printing after the etching process. It is also possible to impart a wide variety of advanced design effects by a combination of a pattern and a hue in an extraction process and a pattern and a hue in a further dyeing or printing process. Examples of the synthetic fiber material used in the present invention include polyester fibers, polyamide fibers, and composite fibers of these fibers and cotton, rayon, silk, acetate, and the like, and include woven fabrics, knitted fabrics, raised fabrics, and nonwoven fabrics. No.
