Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved method for carrier dyeing of polyester textile products.

Polyester fibers are highly crystalline and have a dense fiber structure, so they are more difficult to dye than other fibers. Therefore, in water-based dyeing of polyester textile products, disperse dyes are used, and in order to promote the dyeing and internal diffusion of the dye, (1) a carrier dyeing method using a carrier at normal pressure; (2) a carrier dyeing method using a carrier at normal pressure; Special dyeing methods such as (3) other high-temperature, high-pressure dyeing methods must be implemented. Each of these methods has its own characteristics, and a dyeing method suitable for light is selected depending on the material of the object to be dyed, the performance of the dyeing machine, etc. Among these methods, methods (1) and (2) using a carrier have various drawbacks as shown below.

((a) Carrier spots and tarring that occur when the carrier material is steam distilled and becomes oil droplets during dyeing.

(b) Decrease in light fastness, rub fastness and sublimation fastness of dyed products.

e'l Remaining geary odor on dyed fabrics.

b) Decrease in dyeing reproducibility due to hue change during dyeing.

U → Dye decomposition and dye selectivity.

(f) Suppression of dye adsorption during dyeing.

(1-) Decrease in workability and pollution due to carrier odor.

The present invention eliminates these drawbacks and provides a carrier dyeing method that can dye polyester fiber products very stably and robustly.

In the method of the present invention, polyester fiber products are dyed in a dye bath containing a carrier composition containing dibenzofuran (also known as diphenylene oxide) represented by the following general formula.
It is characterized by staining at 140°C.

The carrier composition mentioned above is usually formed by emulsifying dibenzofuran in water using a suitable emulsifier, and at this time, one kind of other compound having a carrier effect may also be included. For example, the compound is selected from hydrocarbons, esters, phenols, halides, ethers, organic acids, and amines.

The other composition of the dye bath is usually Ut, and the dyeing temperature is 60℃.
-140'C is sufficient.

In the present invention, the following effects can be obtained by using dibenzofuran as a carrier material.

(1,) As shown in Table 1, compared to conventional carrier raw materials, dibenzofuran has almost no steam distillation residue, and therefore no carrier spots or tarring occur due to steam distillation.

(Sho) Collect 200 jj of each type of carrier raw material, perform steam distillation while keeping the distillation rate as constant as possible, and calculate the distillation ratio (volume) of the carrier raw material amount and water amount for each distillate. ), and distillation was performed until the ratio became constant. Distillation total key up to the distillation end point -
The amount of IJ gear raw material and the total amount of water were determined, and the distillation ratio of each gear raw material was calculated therefrom.

(2) There is no decrease in light fastness, rubbing fastness, or sublimation fastness of the dyed product.

(3) There is no residual carrier odor in the dyed product.

(4) There is no deterioration in workability due to carrier odor and no pollution.

(5) There is no decrease in dyeing reproducibility due to hue changes during dyeing.

(6) There is no dye degradability or dye selectivity.

(7) The dyed product shows no myositis and has excellent level dyeing properties.

(8) Dye adsorption is not suppressed if the amount used is within the applicable range.

(9) Less staining of disperse dyes on other fibers.

00) Does not impair the physical or chemical properties of the dyed product.

The concentration of dibenzofuran in the dye bath is not particularly limited, but may be 0.
．． It is preferably from 0.01 to 5 wt%, especially from 0.05 to 5 wt%.
A remarkable effect is obtained when the amount is 2 wt%.

Note that the polyester fiber product to which the method of the present invention is applied means a fiber product containing polyester fiber, and includes threads, woven fabrics,
It includes not only knitted fabrics and nonwoven fabrics, but also blended fabrics, interwoven fabrics, and interwoven fabrics made of polyester fibers and other fibers.

Next, examples of the present invention will be shown, and the carrier compositions used in the examples are as follows. In addition, parts and % in the carrier compositions and examples indicate parts by weight and % by weight unless otherwise specified.
