Color technique.
Background technology
Polyester fiber is hydrophobic synthetic fibers, and the energy as cellulose or protein fibre is lacked in molecular structure
The active group combined with dyestuff.Polyester fiber crystallinity, the degree of orientation are high, and molecules align is closer, is only deposited in fiber
In the gap of very little.Routine to polyester fiber carry out water-bath dyeing when, in order to reach preferable coloring, it is necessary to using
More than more than 130 DEG C high temperature, to ensure that violent warm-up movement occurs for fiber macromolecular, enough momentary clearances are produced, allow dye
Material diffuses into fibrous inside；High temperature can also promote the dissolving and diffusion of dyestuff at the same time, be conducive to dye.To terylene high-temperature dyeing
Do not utilize it is energy-saving, in the existing low temperature dyeing technique to terylene there are color fastness it is not high, dyeing it is uneven the problems such as.
The content of the invention
The object of the present invention is to provide a kind of Polyester fibre disperse dyes in low-temperature dyeing technique, terylene is enabled to dissipate fibre
Dimension has high color fastness and even dyeing in dyeing.
In order to solve the above technical problems, the object of the present invention is achieved like this：
A kind of Polyester fibre disperse dyes in low-temperature dyeing technique according to the present invention, in turn includes the following steps：
Step（1）, under the conditions of 50 DEG C, according to 1：Polyester fibre into the water, is sequentially added acetic acid, low by the bath raio of 8-10
Warm dyeing assistant and disperse dyes, and stir evenly, keep 15min；
Step（2）, 80 DEG C are warming up within the 40-45min times, then 95-100 DEG C is warming up in 10-15min, and keep 30-
40min。
Step（3）, add cold water and be cooled to 80-85 DEG C, and keep 10min；
Step（4）, add cold water cooling, temperature lowering water is to 10 DEG C；40-45 DEG C is warming up in 5-10min again, and keeps 20-
25min；
Step（5）, to step（4）Polyester fibre after processing carries out reduction cleaning 2-3 times；Cleaning to be carried out with clear water dry again
Only, and dry；
Step（1）In, the low temperature dyeing assistant is the emulsion containing organic ester.
As a further illustration of the above scheme, step（1）In, the addition of the acetic acid is to account for the amount of Polyester fibre
It is described scattered than being that to account for the weight ratio of Polyester fibre be 1-3% for the addition of 0.5-2.5%, the low temperature dyeing assistant
The weight ratio that the addition of dyestuff accounts for Polyester fibre is 1-5%.
As a further illustration of the above scheme, step（5）In, the technological parameter of the reduction cleaning is：Soaping agent 2g/
L, thiourea dioxide 2g/L, caustic soda 2g/L, bath raio 1：8-10,85-90 DEG C of temperature, time 10min.
As a further illustration of the above scheme, the soaping agent is paregal O or nonylphenol polyoxyethylene ether.
As a further illustration of the above scheme, organic ester contained in the low temperature dyeing assistant is to include but not
Be limited to dioctyl terephthalate, diethylene glycol dibenzoate, dimethyl terephthalate (DMT), ethyl benzoate, phenyl salicylate,
Fragrant cluster ester type compound including benzyl salicylate.
The beneficial effects of the invention are as follows：A kind of Polyester fibre disperse dyes in low-temperature dyeing technique according to the present invention,
Use containing organic esters such as fragrant cluster ester type compounds, optimized the techniques such as dyeing temperature so that meeting Polyester fibre
On the basis of low temperature color, it may be such that the color fastness of dyeing and uniformity improve with obtaining.
