Description

A kind of cationic black dyes that is used for modified terylene dyeing

Technical field

The present invention relates to a kind of cationic black dyes that is used for modified terylene dyeing, be specially adapted to dye modified dacron and modified dacron and acrylic fibers one-bath dyeing and modified dacron and terylene one-bath dyeing.

Background technology

The output of modified dacron is increasing sharply, the BLENDED FABRIC amount of terylene and modified dacron, terylene and acrylic fibers is also increasing, by traditional handicraft dyeing is to adopt two bath process with DISPERSE DYES and cation dyes respectively, but DISPERSE DYES is a high-temperature pressure dyeing, and cation dyes non-refractory high pressure, therefore select conventional dyestuff can cause Color to descend, particularly the vividness of cation dyes descends, fastness is impaired, to the dyeing of modified dacron and the blended fabric dyeing of modified dacron and acrylic fibers, selecting suitable dyestuff is a difficult problem on the printing technology.

Summary of the invention

The invention provides a kind of cationic black dyes that is used for modified terylene dyeing, solve the problem of the dyeing of two bath process and cation dyes non-refractory high pressure, and vividness is constant, fastness improves.

A kind of cationic black dyes that is used for modified terylene dyeing of the present invention is made up of following component:

Weight fraction is 10～40% the weld as chemical formula (I):

R wherein ₁:-H ,-CH ₃,-OCH ₃

Weight fraction is 10～40% the orchil as chemical formula (II):

R wherein ₂:-CH ₃,-C ₂H ₅

R ₃：-C ₂H ₄CN、-C ₂H ₄Cl、-C2H ₅

Weight fraction is 5～80% the blue dyes as chemical formula (III)

R wherein ₄, R ₅:-CH ₃,-CH (CH ₃) ₂

R ₆、R ₇：-CH ₃、-C ₂H ₅、-C ₂H ₄OH

R ₈：-CH ₃、-C ₂H ₅

R ₉：-C ₂H ₄OH、

R ₁₀、R ₁₁：-H、-CH ₃、-C ₂H ₅、

R ₁₂、R ₁₃：-H、-CH ₃、-C ₂H ₅、-C ₂H ₄CN

Surplus is an auxiliary agent.

Auxiliary agent described in the present invention is a naphthalene sulfonic acid-formaldehyde condensation product, condensation compound of methyl naphthalene sulfonic acid and formaldehyde, or the mixture of the two.

Formula (II)-1 and formula (II) are similarly red cation dyes though-2 chemical constitution is different, and performance is identical, close with other compatbility of dyestuff, use the back effect close, therefore are known as same compounds in the art.

Formula (III)-1, formula (III)-2, (III) are similarly blue cation dyes though-3 chemical constitution is different, and performance is identical, close with other compatbility of dyestuff, use the back effect close, so are known as same compounds in the art.

The weight fraction of above-mentioned weld is preferably 15～30%, and the weight fraction of orchil is preferably 15～30%, and the weight fraction of blue dyes is preferably 35～65%

The cationic black dyes that is used for modified terylene dyeing of the present invention can be pressed the method preparation:

Auxiliary agent is dissolved in the water, under 70 ± 10 ℃ temperature, add weld, the orchil of metering, the independent wiring solution-forming of filter cake of blue dyes respectively, add other wetting agent, spray drying makes weld, orchil and blue dyes respectively then.

Weld, orchil, the blue dyes of gained are added in the mixer according to a certain percentage, add an amount of auxiliary agent again, mix forming compound in 4～8 hours.

Because DISPERSE DYES and cation dyes will produce precipitation when bathing together, and dyeing can not be carried out.Conventional terylene and acrylic fibers BLENDED FABRIC adopt two bath process, respectively with DISPERSE DYES and cation dyes gradation dyeing.The present invention can make terylene and acrylic fabric adopt one-bath dyeing, owing to select the cation dyes after the modification for use, has heat-resisting quantity, and temperature can reach 130 ℃ and the color and luster of cation dyes is constant when one-bath dyeing, and vividness is constant, and fastness ability improves.Cationic black dyes fastness of the present invention is good, lovely luster, and the dye-uptake height has good level-dyeing property.

The specific embodiment

The invention will be further described below in conjunction with example, but protection scope of the present invention is not limited to this.

Example 1～10

With weld, orchil, blue dyes, dispersing agent NNO is added in the mixing machine according to data shown in the table 1, mixed 4～8 hours, must be used for the modified terylene dyeing cationic black dyes.

Weld can select for use Zhejiang Province Runtu intercalated Co., Ltd, Shanghai to celebrate into golden yellow SD-GL, the yellow SD-5GL of dye chemical industry Co., Ltd, the production of Shanghai good industry dye chemical industry Co., Ltd, the yellow SD-GRL that Zhejiang Province Runtu intercalated Co., Ltd produces.Orchil can select for use Zhejiang Province Runtu intercalated Co., Ltd, Shanghai to celebrate into red SD-GRL, the bright red SD-5GN of dye chemical industry Co., Ltd, the production of Shanghai good industry dye chemical industry Co., Ltd, the red SD-2BL that Zhejiang Province Runtu intercalated Co., Ltd produces.Blue dyes can select for use Zhejiang Province Runtu intercalated Co., Ltd, Shanghai to celebrate into blue SD-GSL, the blue SD-BL of dye chemical industry Co., Ltd, the production of Shanghai good industry dye chemical industry Co., Ltd, blue SD-4GSL, blue SD-F2RL that Zhejiang Province Runtu intercalated Co., Ltd produces.
