Description
Technical field
The invention belongs to textile fabric staining technique field, be specifically related to the dyeing side of a kind of polylactic acid textile fiber
Method.
Background technology
Along with the progress in epoch, people have higher requirement to life, and in order to meet the demand in market, Fresh fats is continuous
Producing, wherein chemical fibre develops to ultra-fine direction, it is possible to the binding fiber that complex functionality is strong, and wherein acid fiber by polylactic is one
Planting green fiber, acid fiber by polylactic is to be polymerized by fermentation with the starch material such as Semen Maydis, Semen Tritici aestivi, reels off raw silk from cocoons and makes, and it has performance
Superior, wearing comfort is high, flexible, drapability, hygroscopicity, breathability, thermostability and anti-ultraviolet function, simultaneously because
It has preferable biological degradability, is described as new for environment-friendly type polyester synthetic fibers, the most very popular, but due to
Fiber composition structure problem, dyeing difficulty is higher, when upper dye temperature is too high, the intensity of fiber and extensibility can be made to sustain damage,
If temperature is too low there will be again the problems such as difficult, the fastness difference of dyeing, and more sensitive to alkali and temperature, often therefore can not use
Rule method dyes.
Summary of the invention
It is an object of the invention to for existing problem, it is provided that the colouring method of a kind of polylactic acid textile fiber.
The present invention is achieved by the following technical solutions: the colouring method of a kind of polylactic acid textile fiber, in it
Holding and include processing polylactic acid textile fiber with the inorganic agent containing sulfydryl, the usage amount of inorganic agent is that required process is ultra-fine to be spun
The 3-6% of textured fiber fabric weight；Then with by phthalic anhydride, trinitro-benzene-sulfonic acid, ethyl acetate, to ethylo benzene acetone
The dispersant made with azodiisobutyronitrile carries out pretreatment to natural dye, and the usage amount of dispersant is the natural dye of required process
The 2-4% of material weight；Finally utilize pretreated natural dye that the polylactic acid after processing is spun under conditions of stage heats up
Textured fiber fabric dyes；
Wherein, during the described inorganic agent containing sulfydryl is isooctyl mercaptopropionate, mercaptopropionic acid ethyl ester, double di-mercaptobenzothiazolby
Any one；The percentage by weight of each raw material of described dispersant is as follows: phthalic anhydride 3-7%, trinitro-benzene-sulfonic acid 1-
4%, to ethylo benzene acetone 6-10%, azodiisobutyronitrile 3-5%, surplus is ethyl acetate.
The colouring method of a kind of polylactic acid textile fiber, comprises the following steps:
(1) fabric treating: inorganic agent is put into and is equivalent to the required deionization processing polylactic acid textile fiber weight 6-8 times
In water, after being heated to 48-54 DEG C, insulated and stirred 3-5 minute, then put into staining machine together with polylactic acid textile fiber
In, circular treatment 1.5-2.5 hour, it is cooled to room temperature standby；
(2) prepare dispersant: take ethyl acetate and put in container, add phthalic anhydride after being warming up to 45-50 DEG C, stir 1-
After 3 minutes, add and ethylo benzene acetone thermal-insulating sealing is placed 1.5-2 hour, be then cooled to room temperature, put into surplus stock, stir
After mixing 10-15 minute, placing 30-40 minute, precipitation, sucking filtration post-drying obtain dispersant；
(3) modification: dispersant is put into and is equivalent to the required deionized water processing polylactic acid textile fiber weight 16%
In, after being heated to 58-64 DEG C, add and be equivalent to the required natural dye processing polylactic acid textile fiber weight 1.8-2.5%
Material, it is standby that insulated and stirred 5-8 minute obtains modified natural dyestuff；
(4) dyeing: being added in staining machine by above-mentioned gained modified natural dyestuff, be warming up to 43-54 DEG C, circular response 15-20 divides
Clock；It is warming up to 54-66 DEG C, circular response 10-15 minute；It is warming up to 66-78 DEG C, circular response 30-40 minute, takes out after dyeing
Polylactic acid textile fiber, with cold water repeated washing repeatedly, soaps, washes, dries.
Being processed polylactic acid textile fiber by the inorganic agent containing sulfydryl in the present invention, suppression polylactic acid spins
The elecrtonegativity of textured fiber so that it is the repulsive force producing modified negative charge reactive dye reduces, and utilizes dispersant to natural
Modification processes, and improves the natural dye diffusion to polylactic acid textile fabric and absorption；Simultaneously under condition of different temperatures
Control to process the time accordingly, improve light fastness and the washing fastness of fabric, be that the crock fastness of fabric improves after dyeing
0.5-1.5 level.
The present invention has the advantage that compared to existing technology and processes according to method in the present invention, shortens dyeing time, fall
Low dyeing temperature, can avoid, owing to high temperature causes intensity and the extensibility damage of fiber, reducing the use of alkali liquor, in raising
Color speed, it is ensured that improve color and luster and the quality of product while polylactic acid textile fabric quality.
