Abstract

The invention discloses a yellow environment-friendly disperse dye composition, and mainly comprises the following components by weight percent: 80-96% of dye monomer A as shown in formula (1), 4-20% of one or more dye monomer B as shown in formula (2), wherein X1 is H or halogen, R1 is an alkyl group of C1-C4 or an alkyl group of C1-C4 of which the H is replaced by a benzene ring. The dye has extremely good lifting power, color fixation rate and degree of exhaustion, excellent compatibility, levelling property, covering performance, favorable various fastness, especially the sublimation fastness and washing fastness of which the advantage surpasses that of disperse yellow 23#, makes up the defects of the sublimation fastness and washing fastness of the disperse yellow 23#.

Description

A kind of Yellow environment-friendly disperse dye composition

Technical field

The present invention relates to a kind of Yellow environment-friendly disperse dye composition, be particularly suitable for dyeing and the stamp of terylene and BLENDED FABRIC thereof, vinegar fibre, polyamide fibre.

Background technology

Along with industrial development, energy consumption is day by day serious, and energy-conserving and environment-protective are increasingly important.Therefore the picture dyeing is had higher requirement to environmental protection and energy saving performance and the dyeing behavior of dyestuff.As DISPERSE YELLOW 23# study recently find in its dye structure to nitrogen benzide have carinogenicity but, low price gorgeous because of its coloured light, lifting force good, exhaust high middle low temperature dyeing and the stamp of being widely used in of rate power.Although the substitute products of existing many environment-friendly types occur on the market now, its energy-efficient performance particularly aspects such as lifting force, dye uptake, degree of fixation has obvious defective.

Summary of the invention

The invention provides a kind of Yellow environment-friendly disperse dye composition, this dyestuff is not only having obvious improvement than original Yellow disperse dye aspect lifting force, degree of fixation, the degree of exhaustion, and the subject range of the pH of this dyestuff is extremely wide, good level-dyeing property, opacifying property good, and particularly sublimation fastness and washing fastness spy are good.

Yellow disperse dye composition of the present invention by weight percentage, mainly comprises following component:

80%～96% suc as formula the dye monomer A shown in (1):

4%～20% one or more suc as formula the dye monomer B shown in (2):

X wherein ₁Be H or halogen, R ₁Be C ₁～C ₄Alkyl or a hydrogen by the cyclosubstituted C of benzene ₁～C ₄Alkyl.

Described dye monomer B is comprised of following one or more dye monomers:

Yellow environment-friendly disperse dye composition of the present invention generally needs to add auxiliary agent during application.Described auxiliary agent is dispersed dye dispersion agent, diffusant and tensio-active agents thereof etc. commonly used when composite, preferably includes one of following or its mixture: naphthalene sulfonic acidformaldehyde condensation product, sulfonated lignin, alkyl naphthalene sulfonic acid formaldehyde condensation products.Such as condensation compound of methyl naphthalene sulfonic acid and formaldehyde (Dispersant MF), naphthalene sulfonic acidformaldehyde condensation product (dispersing agent NNO), benzyl naphthalene sulfonic formaldehyde condensation compound (dispersing agent CNF), sodium lignosulfonate (xylogen 85A, 83A) etc.Usually, the ratio of auxiliary agent and former dyestuff weight is 1.5～7: 1.

Yellow environment-friendly disperse dye composition of the present invention can prepare with following methods: after the former dyestuff of dye monomer is mixed in proportion, in the presence of auxiliary agent, water or other tensio-active agent, carry out corpusculed with pulverizers such as sand mill or shredders, then spraying drying.Above-mentioned dye monomer all can adopt the commercially available prod.

Disperse dye composition of the present invention can be aqueous behind the corpusculed, can be powdery, particulate state after the spraying drying.This dyestuff lifting force, degree of fixation, degree of exhaustion are fabulous, compatibleness is splendid, level-dyeing property, opacifying property, every fastness are all good, especially the superiority of sublimation fastness, washing fastness aspect has surmounted C.I.DISP YELLOW 23# (DISPERSE YELLOW 23#), has remedied the deficiency that DISPERSE YELLOW 23# sublimation fastness is poor, washing fastness is poor.

Embodiment

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

Embodiment 1～17

According to data shown in the table 1, with dye monomer A, dye monomer B, after adding the water blending by certain proportioning and condensation compound of methyl naphthalene sulfonic acid and formaldehyde (Dispersant MF), naphthalene sulfonic acidformaldehyde condensation product (dispersing agent NNO), sodium lignosulfonate (xylogen 85A, 83A), carry out grinding distribution with sand milling, then carry out spraying drying.

The C.I.DISPYELLOW 2# that produces of the optional Zhejiang Province Runtu intercalated Co., Ltd of dye monomer A wherein, C.I.DISP ORANGE 25#, C.I.DISP ORANGE 288#, C.I.DISPORANGE 298# that dye monomer (2-1), (2-2), (2-3) optional Zhejiang Province Runtu intercalated Co., Ltd produce.

Table 1:

The dye composition that dispersed dye, auxiliary agent, the water that above-described embodiment is made makes after mixing carries out performance test, and with DISPERSE YELLOW 23# performance comparison, testing method is as follows:

Respectively get the dispersed dye that 1.0 gram embodiment 1～17 make, water is mixed with respectively the dispersed dye suspension that concentration is 1g/500ml, get 10ml, 20ml, 40ml mixes with the water of 90ml, 80ml, 60ml, dye abundant PH to 5 with the acetic acid adjusting, then be warmed up to 60 ℃, put into respectively simultaneously the 2g trevira and carry out high-temperature pressure dyeing, in 35 minutes, be warmed up to 130 ℃, be incubated 30 minutes, sampling when being cooled to 80 ℃.
