Abstract
The invention relates to a disperse light red dye for superfine polyester fibers, comprising the following components by weight: 50-85% of dye monomer A, 7-40% of dye monomer B, 1-12% of dye monomer C and the balance auxiliary agent. The disperse dye can carry out rapid dyeing and coloring under alkaline condition to achieve high degree of coloring, can further save energy and reduce consumption compared with the common high temperature and high pressure dyes, can rapidly improve the degree of exhaustion, simultaneously improves the color fastness and alleviates sewage discharge and treatment.
Description
Technical field
The present invention relates to a kind of light red dispersed dye, relate in particular to a kind of light red dispersed dye (Disperse Red E-RPD) that are used for polyester superfine fibre.
Background technology
At present, ultra-fine fibre has become the focus textile raw material that domestic and international each weaving manufacturing enterprise is used for developing grade textiles.Because ultra-fine fibre has minimal line density and high-specific surface area, make its fabric have high spreadability, advantage such as soft, therefore ultra-fine fibre is fit to make flock suede, peach face, emulation silk and highly dense series products etc., after entering 21 century, the production technology of ultra-fine fibre and output are expected to occur bigger development, fastest-risingly should be polyester superfine fibre.
Polyester superfine fibre is the kind that national policy is helped and textile chemical fiber is already first developed as the high-end product in the differential high-performance fiber.According to relevant professional person's prediction, China's a few years from now on polyester superfine fibre output will increase with annual 9% speed, the ultra-fine fibre output that was used for tame textile fabrics such as flock suede and high-grade clothing by 2013 will reach 250,000 tons, domestic demand to the special-purpose dispersed dye of polyester superfine fibre also will increase with annual about 15% speed, to reach 15,000 tons to domestic needs amount in 2013.
But when polyester superfine fibre was dyeed, the colour system of the same degree of depth was after 130 ℃ of dyeing, and the dyestuff dye uptake is lower.If dyestuff exhaustion percentage is low in the dye liquor, dyestuff content is just than higher in the sewage, and every colour fastness of dyed shell fabrics is also very poor, and therefore, the dye product of high dye exhausting rate of market in urgent need and high color fastness satisfies market demand.
Summary of the invention
The technical issues that need to address of the present invention provide a kind of high dye exhausting rate and high color fastness light red dispersed dye that are used for polyester superfine fibre.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
A kind of light red dispersed dye that are used for polyester superfine fibre is characterized in that this dyestuff is made up of following component:
Weight fraction is the dye monomer A as chemical formula (1) of 50-85%,
Weight fraction is the dye monomer B as chemical formula (2) of 7-40%,
Weight fraction is the dye monomer C as chemical formula (3) of 1-12%,
All the other are auxiliary agent.
As limitation of the invention further, the weight fraction of described dye monomer A is 60-72%, and the weight fraction of described dye monomer B is 15-34%, and the weight fraction of described dye monomer C is 5-8%.
Described auxiliary agent comprises one of following or its mixture, sodium lignosulfonate (xylogen 85A, 83A) and condensation compound of methyl naphthalene sulfonic acid and formaldehyde (Dispersant MF).
Dispersed dye of the present invention can prepare in accordance with the following methods: will measure former dye monomer A, the dye monomer B of ratio and dye monomer C after pre-dispersed smashing, add the dissolving of auxiliary agent and warm water dispersed with stirring, repeat through continuously grinding and filtration, sand milling to terminal after, send by pipeline and to put the spray-drying tower drying, evenly spray into simultaneously dust laying oil and dispersion agent, the end product packing.The waste gas of output is by cyclone dust collector, by the several dust removal by filtration in the spraying drying.
C.I. disperse red 60, C.I. Disperse Red 92 and C.I. Red-1 200 46 that dye monomer A, dye monomer B that the present invention adopts and dye monomer C can select for use Jiangsu Ya Bang Dye Co., Ltd to produce.
Color Index (C.I.) is the meaning of " Colour index number ", and it is international dyestuff title.
After adopting technique scheme, the beneficial effect that the present invention obtains is: can dye in very wide pH scope (dispersed dye generally are slightly acidic dyeing), can paint fast and reach high dye uptake, more energy-saving and cost-reducing than common high-temperature pressure dyeing, improve every colour fastness simultaneously, and alleviated sewage emissions and processing.
Embodiment
The present invention is further detailed explanation below in conjunction with embodiment, but protection scope of the present invention is not limited to this.
Embodiment 1-12
Press data shown in the table 1, with metering former dye monomer A, the dye monomer B of ratio and dye monomer C after pre-dispersed smashing, add the dissolving of dispersion agent and warm water dispersed with stirring, repeat through continuously grinding and filtration, sand milling to terminal after, send by pipeline and to put the spray-drying tower drying, evenly spray into dust laying oil and dispersion agent simultaneously, the end product packing.
Table 1
The dispersed dye that the foregoing description is made carry out the composite performance test, and testing method is as follows:
Respectively get the dispersed dye that 0.5g embodiment 1-12 makes, water is mixed with the dispersed dye suspension that concentration is 0.5g/500mL respectively, getting 20mL mixes with the water of 80mL, regulate dye bath pH to 4.5-5.0 with acetic acid, be warmed up to 60 ℃ then, put into the 2g polyester superfine fibre simultaneously respectively 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 ℃.Observe cloth specimen coloured light and adopt GB/T3921, GB/T3920-1997, GB/T5718-1997 to measure its dyefastness, adopt the GB/T9337-2009 method to measure the dyestuff dye uptake.Measurement result sees Table 2.
