Description
Technical field
The present invention relates to textile dyeing and finishing technology, in particular to a kind of dyeing of dacron.
Background technique
Polyester fabric is very more a kind of chemical fiber garment fabrics in daily life.Its general processing method is divided into
Pre-treatment, dyeing, post-processing three phases, wherein polyester knitting object pretreatment procedure is mainly oil removing, after the completion of pre-treatment, dye
It generally further include a step reduction cleaning, step washing neutralizes and the processes such as a step hot water wash after color is completed；Due to polyester fiber
Feel is harder, and general dacron is both needed to carry out soft finish.We can see that the dyeing and finishing in existing polyester fiber is processed
In the process at least will be by six bath manufacturing procedures, it is more to show production process, and water consumption is high, and energy consumption is high, and production capacity is low etc. asks
Topic, leads to that environmental pollution is serious, high production cost.
Summary of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of time-consumings short, high production efficiency, water, electricity, vapour
Consumption is few, moreover it is possible to improve the terylene pre-treatment, dyeing, post-processing one bath dyeing technology of dyeing and finishing efficiency.
In order to achieve the above object, a kind of terylene pre-treatment of the invention, dyeing, post-processing one bath dyeing technology, it is wrapped
Include following steps:
First cloth is put into dye bath, bath raio 1:5, normal temperature condition be added 2 grams per liter of degreaser, 1 grams per liter of levelling agent and
0.5 grams per liter of glacial acetic acid makes pH reach 4-5, and dyestuff is added and keeps 5min；120- is warming up to 1-2 DEG C/min heating rate again
130 DEG C, soaking time 20-60 minutes；70 DEG C -75 DEG C are cooled to the cooling rate of 0.8-1 DEG C/min again, is directly added into soda ash
2-4 grams per liter adjusts PH to 9.5-10.5, and reducing agent 3-6 grams per liter is added, is then warming up to 90-95 with 1-2 DEG C/min heating rate
DEG C, insulation reaction 20-30 minutes；60 DEG C finally are cooled to the cooling rate of 0.8-1 DEG C/min, is drained.
Preferably, the degreaser is high temperature resistant degreaser BOR.
Preferably, the levelling agent is nonionic leveler LD.
Preferably, the dyestuff is the dyestuff of its production of Town in Shanghai promise.
Preferably, the reducing agent is sodium hydrosulfite.
130 DEG C, insulation reaction 20-60 minutes are warming up to preferably, being added after dyestuff with 1 DEG C/min heating rate.
Preferably, being cooled to 70 DEG C -75 DEG C with the cooling rate of 1 DEG C/min, it is directly added into soda ash and reducing agent.
90 DEG C are warming up to 1 DEG C/min heating rate preferably, being added after soda ash and reducing agent, insulation reaction 25 is divided
Clock.
Preferably, being finally cooled to 60 DEG C with the cooling rate of 1 DEG C/min, drained.
The present invention completes pre-treatment, dyeing and post-processing using one-bath deoiling, dyeing, reduction single bath process, and degreaser belongs to
Nonionic, pH value 7, levelling agent pH value are 7, and ice vinegar pH value is 2-3, and dye liquor pH can be made to reach 4-5.Bath does not influence to dye altogether,
It is contaminated on while oil removing, after the completion of dyeing, cools to 70 DEG C -75 DEG C, directly plus soda ash, neutralize and adjust PH to 9.5-10.5, protected
Card reducing agent plays stabilization after being added, and has better reduction effect, to reach better fastness.It is verified by bulk production,
Fabric quality, fastness, gloss are fine, have not only improved the quality of product in this way, but also play the role of energy saving.
Beneficial effects of the present invention:
1,2 hours of dacron dyeing and finishing saving of time, steam water power consume 500 yuan of cloth save the cost per ton or more, energy
For water consumption electricity vapour than former multistep processes technique decline 20%, labour efficiency promotes 25%.
2, fabric washing color fastness, water-fast, colour fastness to perspiration and the photochromic fastness of sweat mention at 4 grades or more than original process
It is half grade high.
For the present invention by selection suitable dye auxiliary agent, adjustment dye bath index etc. realizes that pre-treatment, dyeing, reduction cleaning arrange
It is completed with bath；The terylene pre-treatment dyeing reduction single bath process that invention provides, original more bath process are merged and are executed, were both reduced
Water consumption, electricity, steam consumption, while reducing atmosphere and water pollution, moreover it is possible to improve 50% or more dyeing and finishing efficiency.
