The invention discloses a kind of polyester knitted fabric high color fastnesses to lack watermark dyeing technique, and by first by pre-setting under polyester knitting object hot conditions, not venting raffinate after dyeing after directly cooling down, is added acidic reduction agent and carries out reduction cleaning.Loose colour can effectively be removed by carrying out reduction cleaning with dyeing residual liquid, not fixed dyestuff is set to be reduced cleaning removal, it saves water, simplification of flowsheet, save the cost, it is low-temperature shaped without direct wet cloth is dried after cleaning, without high-temperature process, the migration and distillation for reducing dyestuff under high-temperature shaping are conducive to the color fastness for improving dacron.
Description
Technical field
The present invention relates to dyeing and printing process field, it is more particularly to a kind of polyester knitted fabric high color fastness and lacks watermark dyer
Skill.
Background technique
With polyester fabric in clothes using more and more extensive, everybody is relatively more to the color fastness concern of terylene, is
The loose colour and remaining oligomer for removing fabric surface are to improve dyefastness, it usually needs after dyeing carry out restoring clear
It washes, conventional reduction cleaning is to carry out under alkaline condition, needs venting dyeing residual liquid, carries out repeatedly rinsing and acid neutralizes, water
Wash, production procedure is long, and it is time-consuming, energy consumption is larger.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of polyester knitted fabric high color fastnesses to lack watermark dyeing technique,
Polyester knitted fabric color fastness is improved, simplification of flowsheet saves water, reduces cost.
To achieve the above object, the present invention provides the following technical scheme that polyester knitted fabric high color fastness lacks watermark dye
Technique, comprising the following steps:
(1) pre-setting, polyester knitted fabric is through high temperature pre-setting, 190 DEG C -205 DEG C of temperature, speed 38-45m/min, terylene into
The processing of row high temperature pre-setting, the molecules align of regular terylene, to improve the dimensional stability of woven dacron, with good pendency
Property and gas permeability；
(2) it dyes, 128 DEG C -132 DEG C of dyeing temperature, dyes 50 min -60min of soaking time；
(3) reduction cleaning, not venting raffinate after dyeing are directly cooled to 80 DEG C, are added acidic reduction agent, isothermal holding,
Washing, dacron disperse dyeing generally carries out under mild acid conditions, due under the conditions of ordinary stain disperse dyes to washing
The dye-uptake of synthetic fibre is higher, carries out reduction cleaning using acidic reduction agent and does not need drain, to save water resource.Do not adjusting PH
Reduction cleaning directly is carried out with dyeing residual liquid under conditions of value, simplification of flowsheet reduces cost；
(4) wet cloth is low-temperature shaped, and 120 DEG C -130 DEG C of setting temperature.The lesser disperse dyes of dyeing terylene molecular weight, through excessively high
The fiber through-dyeing of high temperature pressure dyeing is good, and when terylene thermal finalization, the process reverse with upper dye, portion can occur for the dyestuff of fibrous inside
Divide dyestuff that can move to fiber surface again, leads to terylene color fastness decreased, the temperature of thermal finalization is higher, and the migration of dyestuff is got over
Greatly, the color fastness decreased of fabric is big, and therefore, after dyeing reduction cleaning, wet cloth is low-temperature shaped, without baking process, both saves
One procedure shortens process flow, under the premise of the thermal finalization effect for guaranteeing polyester knitting object, will not influence the color of fabric
Fastness.
Further, in the step (2), 130 DEG C of dyeing temperature, soaking time 60min is dyed.
Further, it states in step (2), dyeing is that 3 DEG C/min of room temperature is warming up to 80 DEG C, then is warming up to 1 DEG C/min
130 DEG C, heat preservation dyeing 60min.
Further, in the step (3), after dyeing, 80 DEG C are cooled to 2 DEG C/min.At high operating temperatures, if it is warm
Rapid drawdown is spent, fabrics cloth cover can be made to wrinkle, influence product quality.
Further, in the step (3), the addition acidic reduction agent isothermal holding time is 15min.In acidic reduction agent
Under the conditions of, abundant reduction cleaning removes the loose colour on dacron surface, improves color fastness.
Further, the acidic reduction agent dosage is 3-5g/l, and acidic reduction agent is is sold general acidic reduction on the market
Agent.
In conclusion the present invention passes through first by pre-setting under polyester knitting object hot conditions, venting is not residual after dyeing
Liquid after directly cooling down, is added acidic reduction agent and carries out reduction cleaning, carrying out reduction cleaning with dyeing residual liquid can effectively remove
Loose colour makes not fixed dyestuff be reduced cleaning removal, saves water, simplification of flowsheet, save the cost.After cleaning without
It crosses that dry direct wet cloth low-temperature shaped, without high-temperature process, reduces the migration and distillation of dyestuff under high-temperature shaping, be conducive to
Improve the color fastness of dacron.
