Description

Basic dye composition and dyeing method and dyed product using the basic dye composition

The present invention relates to a basic dye composition suitable for dyeing acrylic fiber or basic dyeable synthetic fiber (Cation Dyeable Polyester; CDP) (hereinafter also referred to as "CDP fiber"), and the use of the basic dye The dyeing method of the composition and the dyed product.

It is known that dyes for the three primary colors of yellow, red, and blue are used in the dyeing of acrylic fibers or CDP fibers using basic dyes, and these dyes are mixed in various ratios (for example, refer to Patent Documents 1 to 5).

Regarding the basic dyes used in the three primary colors, each dye must have excellent build-up, approximately the same dyeing speed of the three primary colors, consistent temperature dependence, and excellent color development and fastness of the three primary colors.

However, in recent years, attention has been paid to moisture absorption and heat generation as a fashion or functionality, and the blending and interweaving of acrylic fibers and CDP fibers has continued to expand.

In the past, basic dyes used in the three primary colors did not cause problems when acrylic fibers or CDP fibers were used alone. However, in the blending and interweaving of acrylic fibers and CDP fibers, the dyeing behavior is different due to the difference in affinity. , Resulting in the problem of uneven dyeing and poor reproducibility. Therefore, the three primary colors that can be dyed uniformly and have excellent reproducibility are strongly expected.

In order to solve such problems, various studies have been conducted, but satisfactory results have not been obtained (for example, refer to Patent Document 1). [Prior Technical Document] [Patent Document]

[Composition example of basic dye composition] According to the combination of basic dyes shown in Table 1 below and the usage amount of these, the basic dye compositions of formulation examples 1 to 18 and comparative formulation examples 1 to 9 were prepared. The numerical values in Table 1 indicate the usage amount of each basic dye (unit: part).

[Table 1]

[Assessment] Each basic dye composition obtained was evaluated by dyeing distribution test and fastness test.

(Dyeing distribution test) (1) Sequence To each of the basic dye compositions and 1 part of acetic acid in the formulation examples 1 to 18 and the comparative formulation examples 1 to 9 shown in Table 1 was added water to prepare a dye bath of the total amount of 600 parts. In the dye bath, 25 parts of Acrylic Muslin (acrylic Muslim thin cloth) (manufactured by Mitsubishi Chemical Co., Ltd., obtained from Color Dyeing Co., Ltd.) and CDP knitting (``cationic dyeable polyester Knit Smooth (processing) (Series)", Teijin (Stock), obtained from (Stock) Color Dyeing Co., Ltd.) 25 parts of 2 types of fiber materials, treated at 40°C for 10 minutes, heated at a temperature rise rate of 1°C/min to a tip temperature of 100 ℃ or 105℃. After dyeing the fiber material at the temperature of each tip for 60 minutes, it is washed with water. Then, in 1000 parts of an aqueous solution containing 2 g/L of a commercially available soaping agent (Kayatector E, manufactured by Nippon Kayaku Co., Ltd.), 2 g/L of bisulfite, and 1 g/L of caustic soda at 70°C After 15 minutes, washing and drying were performed to obtain a dyed product.

(2) Judgment method Use color eye CE7100 (manufactured by Macbeth) to measure the concentration (lightness L ^* ) and hue (a ^* , b ^* ). The color difference ΔE is calculated using the CIE color difference equation. The relative concentration of the CDP knit staining material based on the Acrylic Muslin staining material (Acrylic Muslin staining material concentration: 100) and the color difference ΔE are shown in Table 2 below. The closer the relative density system is to 100, the better, and the closer the color difference ΔE system is to 0, the better.

[Table 2]

(3) Test results As shown in Table 2, even when any of the basic dye compositions of Formulation Examples 1 to 18 are used, the difference in concentration and the change in hue are still very small, and the difference in dyeing and distributing properties of Acrylic Muslin and CDP Knit is small. The results show that the basic dye compositions of formulation examples 1 to 18 can uniformly dye fiber materials containing acrylic fiber and CDP fiber blends, interwoven fabrics or interwoven fabrics. On the other hand, the basic dye compositions of Comparative Formulation Examples 1 to 9 have a larger difference in the concentration of Acrylic Muslin and CDP Knit than the basic dye compositions of Formulation Examples 1 to 18, and the color difference ΔE is also larger.

In addition, even if the mixing ratio of Acrylic Muslin and CDP Knit is changed, the dyeing and distributing properties when using the basic dye compositions of Formulation Examples 1 to 18 are still the same results (data not shown). The results show that the basic dye compositions of Formulation Examples 1 to 18 can uniformly dye fiber materials such as blended fabrics containing these fibers regardless of the mixing ratio of acrylic fibers and CDP fibers.

(Fastness test) (1) Test preparation Water was added to each of the basic dye compositions of Formulation Examples 1, 4, 5, 8, 10 to 17 shown in Table 1, and 1 part of acetic acid to prepare a dye bath of 600 parts in total. Put 50 parts of the woven fabric of acrylic fiber and CDP fiber into the dye bath, and after treatment at 40°C for 10 minutes, it was heated at a temperature increase rate of 1°C/min to the tip temperature of 105°C. After dyeing the cross-knitted fabric for 60 minutes at the tip temperature, it is washed with water. Then, in 1000 parts of an aqueous solution containing 2 g/L of a commercially available soaping agent (Kayatector E, manufactured by Nippon Kayaku Co., Ltd.), 2 g/L of bisulfite, and 1 g/L of caustic soda at 70°C After 15 minutes, washing and drying were performed to obtain a dyed product.

(2) Lightfastness (JIS L 0843) According to JIS L 0843, the color fastness to xenon arc lamp is implemented. It is carried out under the conditions of irradiation illuminance of 50W/m ² (wavelength 300 to 400nm), BPT (black panel temperature) of 63°C, relative humidity of 50%, and irradiation exposure of 7100kJ/m ² . The evaluation judgment is expressed by a grade, which shows the same degree of discoloration and fading as the blue scale (Blue Scale) irradiated at the same time. Grade 5 means the strongest light resistance, and grade 1 means the weakest light resistance. The results are shown in Table 3 below.

(3) Washing (JIS L 0844) Implement the fastness to washing according to JIS L 0844. Acrylic and cotton were added to the dyed fabric as an additional white cloth, and treated with the A-2 method (Marseile soap 5g/L, liquid volume 100mL, 50°C, 30 minutes). The evaluation is based on the gray standard for pollution, JIS　L　0805, which expresses the pollution degree of the additional white cloth in grade. Level 5 represents the best result, and level 1 represents the worst result. The results are shown in Table 3 below.

[table 3]

(4) The results are shown in Table 3. All of the dyed products obtained by using the basic dye compositions of formulation examples 1, 4, 5, 8, 10 to 17 to test for fastness to light are all "5" means excellent light resistance. In addition, in the washing fastness test, any dyed product also represents a high grade of "5" or "4-5", and it is not easy to fade or color transfer due to washing, and it shows that the washing fastness is also excellent.
