Description
Technical field
The present invention relates to textile technology fields, and in particular to a kind of acid dyes continuous pad dyeing method of polyamide fibre ribbon.
Background technique
For nylon fibre because of its intensity height, wearability, resilience are good, are widely used in pure spinning or blended various dress materials and needle
Fabric, especially by its blended brocade/cotton mixture fabric, feel is good, and the comfortable features of clothing and gas permeability of production are preferable while resistance to
Mill property and wear are preferable, popular among consumers, belong to medium-to-high grade raw material.
Acid dyes is the common dyes of nylon fabric dyeing, and coloring is bright-coloured, and dyeing percentage and dyefastness are higher, especially
Its dyeing that nylon fabric is carried out by the way of pad dyeing, high production efficiency, batch difference are small.But using in acid dyes pad dyeing
After contaminating polyamide fibre ribbon, the anti-color fastness after arranging that burns of polyamide fibre ribbon is poor.
Publication technology " continuous pad dyeing method of a kind of polyamide fibre and its blended fabric ", without reference to polyamide fibre ribbon
Dyeing, slim ribbon are unable to reach predetermined dye level, can not solve the problems, such as that the anti-arrangement color fastness that burns is lower；A kind of " raising
The method of textile pad dyeing degree of fixation ", alcohol-based mixtures are added, main function is the stability for maintaining dyestuff in dye liquor, drop
The hydrolysis of low dye improves the utilization rate of dyestuff；" a kind of nylon fabric continous way open-width scouring dyeing " is related, technique mistake
In cumbersome, without reference to the dyeing of polyamide fibre ribbon, can not solve the problems, such as it is anti-burn arrange after color fastness it is lower.
Summary of the invention
The technical problems to be solved by the present invention are: the dyeing of polyamide fibre ribbon is deep after using conventional acid dyestuff pad dyeing dyeing
Degree not enough and it is anti-burn arrange after the poor problem of color fastness, the present invention provides a kind of polyamide fibre ribbons to solve the above problems
Acid dyes continuous pad dyeing method.
The present invention is achieved through the following technical solutions:
A kind of the step of acid dyes continuous pad dyeing method of polyamide fibre ribbon, the continuous pad dyeing method, is successively are as follows:
Step 1, polyamide fibre ribbon pre-treatment；
Step 2, using infrared ray or hot-air seasoning；
While pad dyeing acidity dye liquor and color fixing agent step 3,；
Step 4, decatize dyeing and a fixation treatment are carried out；
Step 5, hot water wash；
Step 6, second of fixation treatment is carried out；
Step 7, hot water wash；
Step 8, it dries；
Step 9, band is fallen.
Preferably, in the step 3, pad dyeing temperature is room temperature or 50 ± 10 DEG C；It is described acidity dye liquor include bleeding agent,
The mixture of acid-releasing agent and one or more acid dyes；The color fixing agent uses anionic fixative.
The acid-releasing agent is organic acid-releasing agent and inorganic acid-releasing agent, and as temperature increases, gradually oxytropism is sliding for Value in Dyeing Process
It moves, compares glacial acetic acid and ammonium sulphate buffer, reduce process and error that buffer (pot-life is short) is prepared in repetition, dyeing
Process is more convenient, and the level-dyeing property of dyeing product is more preferable, and feel is more soft；The color fixing agent used is that can use with same bathe of dye liquor
Anionic fixative, dye liquor and color fixing agent can effectively improve dye level and dye liquor exhaustion rate with bath use, and environmentally friendly is same
When dyestuff consumed cost is greatly lowered；
Preferably, the bleeding agent uses bleeding agent 5881D；The acid-releasing agent uses acid-releasing agent CTA-D；The acid dye
Material uses acid dyes of this field conventionally used for polyamide fibre ribbon, such as acid golden yellow, acid red, acid green, acid blue, acid hiding
Blueness etc..
Color fixing agent used herein is Cationic fixing agents, can be effectively improved with anion fixation treatment compound action
Dye the anti-color fastness after arranging that burns of polyamide fibre ribbon.
Preferably, the Cationic fixing agents use color fixing agent FK-408.
Preferably, in the step 2, drying temperature is 80~150 DEG C.
Preferably, in the step 4, steam temperature control is 98~120 DEG C.
Preferably, in the step 6, the color fixing agent used is Cationic fixing agents；Color fixing temperature is 80 ± 5 DEG C.
Preferably, it in the step 7, is successively carried out using 80 ± 5 DEG C, 70 ± 5 DEG C, 70 ± 5 DEG C, 60 ± 5 DEG C of hot water
Washing four times.
Preferably, in entire continuous dyeing process, speed is 5~15m/min, ratio of elongation 100%.
The present invention provides a kind of acid dyes continous way pad dyeing methods of polyamide fibre ribbon, except individual light color, thin polyamide fibre are knitted
Band, polyamide fibre ribbon need not move through concise Deng pre-treatments；Light, slim polyamide fibre ribbon is only needed by conventional pre-treating technology,
That is: light, slim polyamide fibre ribbon only needs the capillary effect for improving nylon fibre by uniform refining process, ensures polyamide fibre fibre
The chemical reaction activity of dimension is identical, can be avoided light dyeing defect, guarantees the upper dye depth of slim polyamide fibre ribbon.Because of the acidity
Dyestuff pad dyeing polyamide fibre ribbon is chemical bonding, and dyestuff anchors at the surface of fiber by the effect of ionic bond, Van der Waals force, hydrogen bond
And amorphous region, capillary effect, dye radical quantity of dyeability and nylon fibre etc. are related.The present invention is pre- using infrared or hot wind
The method of baking ensure that the water content of polyamide fibre ribbon is consistent with hydroscopicity, and then the uniformity and depth of dyeing has been effectively ensured
Degree.The acid dyes is suitable for the common all acid dyes in market.The process of padding can carry out in 50 DEG C or so of temperature,
Effectively avoid dyeing batch caused by due to dyeing defect caused by temperature is excessively high and dye liquor temperature are different poor；Steam temperature control is 98
~120 DEG C, advantageously ensure that the color development of polyamide fibre 6 and polyamide fibre 66, it is ensured that the high efficiency and quality of dyeing course.Continuous dyeing process
Speed is controlled in 5-15m/min, in favor of ensuring dyeing quality and production efficiency.
The present invention has the advantage that and the utility model has the advantages that
The present invention is conducive to improve the dye liquor exhaustion rate in dyeing course, and dye dosage is few, and discharge of wastewater is low, varietal adaptation
It is good, good quality and more environmentally-friendly.Selecting acid dyes pad dyeing polyamide fibre ribbon is suitable for producing in enormous quantities, and bright degree is high,
Even property is good, and color difference is small, is easier to the dark color (compared to dispersion pad dyeing) of dye, after two kinds of compound fixation of fixation mode, knits after dyeing
Band it is anti-burn arrange after color fastness be improved significantly.It is particularly suitable for the dyeing of 66 ribbon of polyamide fibre 6 and polyamide fibre, color is fresher
Gorgeous, color fastness is more preferable after preventing bright arrange；
The present invention provides a kind of acid dyes continous way pad dyeing methods of polyamide fibre ribbon, which comprises except individual
Light, thin polyamide fibre ribbon, polyamide fibre ribbon need not move through concise Deng pre-treatments；The present invention selects acid dyes steam method and fixation
Co-bathing dyeing scheme make polyamide fibre ribbon color it is fresher, the dye level of polyamide fibre ribbon is effectively improved, to the dye of polyamide fibre ribbon
During color, there is preferable depth, dense dark color can be contaminated to obtain；The acid dyes is chemistry knot to the dyeing of polyamide fibre ribbon
It closes, shifting dye can be carried out by part of auxiliary, repairs color, chromatography；Acid dyes pad dyeing brocade silk weaving band, the secondary fixation scheme in front and back are multiple
Cooperate to use, be chemical bonds between dyestuff and ribbon, in conjunction with fastness is compared, after the anti-arrangement of burning of polyamide fibre ribbon can be effectively improved
The poor problem of color fastness.
