Description

TECHNICAL FIELD [0001] The present invention relates to a dye composition for dyeing an acrylic / wool blend fiber 1, and a dyeing method using the dye composition for dyeing acrylic / wool blended fiber 1,

The present invention relates to a dye composition for dyeing an acrylic / wool blend fiber 1, and more particularly, to a dye composition for dyeing an acrylic / wool blend fiber which comprises a cationic dye and a wool reactive dye coated and dispersed by a naphthalene- , It is possible to replace 1-bath or 2-bath dyeing process of conventional acrylic / wool blend fibers to enable 1-bath dyeing without precipitation formation, maximize process efficiency and economical efficiency, (Acrylic / Wool blended fabrics) dye composition for one-bath dyeing capable of imparting excellent dyeing properties such as color fastness and build-up along with full color development of black color, The present invention relates to a method for dyeing a single bath of acrylic / wool blend fibers.

Polyacrylic is a vinyl-based fiber including acrylonitrile (AN), which is formed of a high molecular material made of hydrocarbon (see the following structural formula 1), and typically has an AN content of 85% or more, fiber, and an AN content of about 85 to 35% is called Moda acrylic fiber. An important structural feature of PAN, a pure polymer with AN alone, is the presence of strongly polarized nitro groups in the molecular chains. This nitro group exhibits strong repulsive force when arranged in the same direction, and strong attraction force in the opposite direction. As a result, neighboring nitro groups repel each other in the same molecular chain, so that each of the molecular chains has a structure of irregular spiral stiffness.

[Structure 1] Structure of acrylic fiber

Cationic dyes (also known as cationic dyes or basic dyes) used in dyeing acrylic fibers are a mixture of dyes having a positive positive charge on an atom (usually a nitrogen atom) and dyes having a positive whole molecule The cationic dyes can be classified into two types. Actually, cationic dyes are cationic dyes.

[Structural Formula 3] Cationic cationic dyes having a positive (+) charge spread throughout the molecule

Wool (wool fiber) is composed of a protein called keratin (see Structure 4 below). The keratin has a structure in which a polypeptide chain obtained by dehydration condensation between a carboxyl group and an amino group of an alpha -amino acid is a main chain and has a structure linked by many crosslinks, and only about 20% of the total crystal portion exists. This fact is recognized as one of the reasons why wool fibers are superior in dyeability to silk.

[Structural Formula 4] Structure of Wool Fiber

However, wool has a dense layer on the surface of the fiber, and boiling dyeing is necessary because the swelling is slow unless it is elevated in an acid bath. The bonding seats of the wool are amino groups and carboxyl groups at the ends of the main chain and the side chain, and the amide bond (-CONH-) in the main chain affects the dyeability, and seated segregation by hydrogen bonding can not be ignored.

Dyes for dyeing wool fibers can be classified into two types. Acid metal complex dyes and wool reactive dyes are the most commonly used dyes.

Metal complex dyes (1: 1, 1: 2 metal complex dyes)

[Formula 6] Wool reactive dye

Acrylic / wool blended fabrics are mainly used for cheap clothing and bedding products compared to 100% wool products. Recently, however, due to the high value added products of consumers, Are activated. Specifically, at present, the mixing ratio of the acrylic fibers and the wool fibers is often set to about 7: 3.

However, in such a case, in order to stain dyeing, it is usually necessary to perform a dip dyeing process of one-bath two-step (or two-bath), and productivity and efficiency are deteriorated due to processing time, energy, wastewater treatment and the like.

In particular, as the mixing ratio of acrylic / wool blend fibers increases from 9: 1 and 8: 2 to about 7: 3 and 5: 5, a large amount of acidic, wool reactive dyes capable of dyeing wool fibers must be added. There is a problem in that a bond is formed between the cationic dye having the property and the wool reactive dye having the anionic property and the dye is precipitated. This is the reason why acrylic / wool blend fibers could not be dyed with 1 bath until now.

Accordingly, the present invention solves the problems of precipitation formation due to binding between dyes and enables one-bath dyeing to dramatically improve the efficiency and economical efficiency of the process, and has excellent dyeing properties such as fastness and build-up The development of new acrylic / wool blend fiber 1 dye for bath dyeing that can be implemented together is an urgent point.

It is important to control the dyeing temperature because acrylic fiber has a low thermosetting temperature. Also, since the scales unique to wool fibers are decomposed when the temperature rises when dyeing wool fibers, dyeing is performed by raising temperature and constant temperature under 100 ° C. Process. Accordingly, the present invention provides a method for dyeing acrylic / wool blended fibers (soaking) by maintaining the temperature of a salt bath (actual fiberizing temperature) at 90 to 100 ° C for 30 to 60 minutes (more specifically, 30 to 40 minutes) do.

The salt bath may be prepared by adding a dye solution ("disperse dye") prepared by dispersing the above-mentioned dye mixture composition in water. Here, the amount of the dye (dye-containing composition) is suitably 0.5 to 8% of the weight of the fiber to be dyed and the amount of the bath is about 20 times the weight of the fiber.

After the fibers to be dyed are charged into the thus-prepared bath, the temperature of the bath is sequentially regulated and maintained for each section as in steps S1) to S4).

The disperse dye and the salt bath may contain, if necessary, glacial acetic acid, a dispersing agent (for example, a naphthalene dispersant and a polyoxyethylene oxide alkyl alcohol dispersant), a softener (for example, an emulsion in which an ester type elastic polymer is emulsified and dispersed) , Polyoxyethylene nonylphenyl ether) may be further included. They are preferably added to water in an amount of about 0.5 g / l.

In addition, after step S4), a step of soaping and rinsing the dyed fabric may be additionally performed.

In addition, in the submersion according to the present invention, pH adjusters such as CH ₃ COOH and CH ₃ COONa can be used together with dyes in addition to the dyes. In order to prevent the dyes from being easily released after being adsorbed onto the fibers, The fastness can be further improved. Here, the fixing agent may be used in an amount of 1 to 12 g / l, preferably 10 g / l, in a dyeing material, but is not limited thereto.
