Description
Technical field
The present invention relates to polyester filament preparation technical field, in particular to a kind of dyeing of polyester fiber.
Background technique
Terylene is an important species in synthetic fibers, is the product name of China's polyester fiber.It is with essence to benzene
Dioctyl phthalate (PTA) or dimethyl terephthalate (DMT) (DMT) and ethylene glycol (EG) are raw material through esterification or transesterification and polycondensation reaction
Prepared by fiber-forming polymer --- polyethylene terephthalate (PET), through spinning and post-process made of fiber.
Since terylene molecular chain structure is close, lacks the hydrophilic radicals such as carboxyl, sulfonic group and direct dyes, acid cannot be used
Property the dyeing such as dyestuff, basic dye.Existing colouring method mostly uses under high temperature and pressure, hot melt or carrier existence condition with dispersion
Dyeing.But in high-temperature pressure dyeing, some disperse dyes high temperature resistant dispersion stabilizations are poor, cause to dye non-uniform ask
Topic often occurs, simultaneously because under high-temperature and high-pressure conditions device security limitation, the small, bath raio of dyeing batch is big, labour is strong
The problem that degree is high, every consumption is big is clearly.
In view of the above problems, needing to be proposed a kind of new solution.
Summary of the invention
The object of the present invention is to provide a kind of dyeings of polyester fiber, which comprises the following steps:
(1) it pre-processes: light alkali solution is made with sodium hydroxide, and degreaser is added, pretreatment fluid is made, then by polyester fiber
It is immersed in pretreatment fluid with certain bath raio, the lower progress within certain temperature certain time of surfactant and fibrillation auxiliary agent is added
It is rinsed after standing, acid solution is then slowly added into mixed liquor, adjust pH value to neutrality, clear water washes clean；
(2) it dyes: dye solution being warming up to 40~60 DEG C, then by the polyester fiber after pre-treatment in step (1) with certain
Bath raio immerses in dye solution, and antistatic prescription is added, and carries out heat preservation dyeing processing at a certain temperature；
(3) it soaps: by the polyester fiber after dyeing in step (2) with certain bath raio merging mass concentration soaping for 4~5g/L
In liquid, reduction cleaning can be suitably added then with 50~60 DEG C of clear water in the 15~25min that soaps under conditions of 90~99 DEG C
Agent 1.5g/L is rinsed well；
(4) fixation: heating fixation liquid is allowed to spray as a vapor, and the polyester fiber after soaping in step (3) is steamed herein
Heat steams 2~3.5h in vapour, then cools to room temperature, is cleaned up with clear water, then dries, bakes at 68~76 DEG C, completes
Fixation treatment；
(5) it winds: the polyester fiber after fixation treatment in step (4) is wound, storage.
Wherein, pretreatment fluid is raw materials used are as follows: sodium hydroxide is 6~7g/L, without phosphorus degreaser is 7~8g/L, dispersing agent
For 0.5~1g/L；Fibrillation auxiliary agent is the YZ-101 of 2-4g/L；And the fibrillation time is 25-30min, fibrillation temperature is 90~95 DEG C.
Start to rinse after the completion, temperature required for rinsing process is 115~130 DEG C, and the retention time is 9~20min.
It is the formic acid solution that mass concentration is 3~5g/L that acid solution, which is added, and rate of addition is 3~7mL/min.
The formula of the dye solution are as follows: 2.5~3.0owf% of dyestuff, 1.5~2g/L of Disperse Leveler, and the dispersion level dyeing
Agent is basic dispersion levelling agent BAH33；1.0~1.5g/L of bleeding agent；The certain temperature is 130~140 DEG C, when heat preservation is dyed
Between 30~70min；Antistatic agent prescription is 1.0g/L.
The color fixing process are as follows: first 90 DEG C are warming up to the rate of 2.5~3 DEG C/min, then with 0.5~1 DEG C/min's
Rate is warming up to 120 DEG C, and constant temperature keeps 10~15min, then is down to room temperature with the rate of 3-5 DEG C/min.
Compared with prior art, the invention has the advantages that: be included in be added in pretreatment and coagent and open
Fine auxiliary agent, can be while carrying out oil removing to polyester fiber, and coagent can be catalyzed oil removal efficiency；Fibrillation auxiliary agent can make
Feel is more soft, plentiful and sliding glutinous after polyester fiber fibrillation, increases the stained area in later period；After rinsing and adjust pH to
After neutrality, using basic dispersion levelling agent BAH33, for some dark dyes without soaping, and it can be reduced when cleaning cylinder body
Clear cylinder number, avoids cylinder body from staiing phenomenon；In addition to this it is easily cleaned after dyeing, cloth cover will not contain alkali, not influence postorder processing
Effect.
Specific embodiment
Below by embodiment, the technical solutions of the present invention will be further described.
Embodiment: a kind of dyeing of polyester fiber sequentially includes the following steps:
