Abstract
The invention discloses a polyester cotton short-process dyeing process, which comprises the steps of firstly adopting a cationic modifier to carry out surface modification on polyester cotton fabric, and then adopting a one-bath two-step method to dye the polyester cotton fabric, wherein the dye liquor comprises the following components: the dye comprises reactive dye, anhydrous sodium sulphate and disperse dye micelle, wherein the disperse dye micelle is prepared by encapsulating disperse dye with amphiphilic polymer containing imine bond. The method can reduce the use of alkali and salt, and the pH value of the dye liquor is adjusted to dye cotton and polyester in two stages, so that the mutual interference of reactive dye and disperse dye is reduced, therefore, the reactive dye and the disperse dye have high dye uptake, and the polyester cotton fabric dyed by the process has full color and luster and excellent friction resistance and light fastness.
Description
Technical Field
The invention belongs to the technical field of dyeing, and particularly relates to a polyester cotton short-process dyeing process.
Background
The dyeing of polyester-cotton blended fabrics adopts a two-bath dyeing process (comprising the steps of dyeing pretreatment, dyeing polyester with disperse dye, reduction cleaning, washing, reactive dye sleeve dyeing cotton and washing), namely, dyeing polyester fiber with disperse dye at high temperature (130 ℃) firstly, reduction cleaning, and then dyeing cotton fiber with reactive dye at normal temperature (below 60 ℃). The traditional process comprises the steps of dyeing pretreatment, dyeing polyester with disperse dye, reduction cleaning, washing, reactive dye sleeve dyeing cotton and washing, and has the defects of complicated working procedures, long processing time consumption and lower production efficiency.
The existing one-bath dyeing of the disperse/reactive dye replaces two-bath two-step dyeing of the disperse/reactive dye, and although the problems caused by the two-bath dyeing can be avoided to a certain extent, the one-bath dyeing of the disperse/reactive dye also has a great number of problems, such as the limitations of the reactive dye and the disperse dye, whether the reactive dye or the disperse dye needs certain specific dyeing performance requirements, the use value is not wide, and the two dyes in one bath can mutually influence, so that the defects of uneven coloring, color difference, low fixation rate and the like are generated. Therefore, development of a polyester cotton disperse dye and reactive dye one-bath dyeing process with wide applicability, uniform coloring and high fixation rate is needed.
Disclosure of Invention
Based on the state of the art, the invention provides a polyester cotton short-process dyeing process which has the advantages of high production efficiency, short process flow, wide dye application, uniform coloring and good leveling property.
The invention is realized by the following technical scheme:
a polyester cotton short-process dyeing process comprises the following steps:
(1) Surface modification: modifying the polyester cotton fabric by adopting a cationic modifier under alkaline conditions;
the cationic modifier is an epoxy compound containing quaternary ammonium, and the alkaline condition is that NaOH is added.
(2) Acid washing
(3) Washing with water
(4) Drying
(5) Dyeing: dyeing the dried fabric;
the dye liquor comprises: 1-3% of owf reactive dye, 50g/L anhydrous sodium sulphate and 0.5-5% of owf disperse dye micelle; in the cotton dyeing stage, the pH value is regulated to be alkalescent, polyester cotton is immersed according to the bath ratio of 1:20, the temperature is increased to 60-80 ℃ at the speed of 2 ℃/min, and the temperature is kept for 30-40 min; the pH value is regulated to be weak acid in the dyeing and washing stage, the temperature is raised to 80-100 ℃ at the speed of 2 ℃/min, the temperature is kept for 20min, the temperature is reduced to 40 ℃, and the dye water is discharged and is reinjected into clear water;
the alkali for adjusting the pH value of the dye liquor is sodium carbonate, and the acid is hydrochloric acid.
The disperse dye micelle is prepared by encapsulating disperse dye with amphiphilic polymer containing imine bond.
The amphiphilic polymer has the following molecular structure:
wherein n has a value of 180 to 320.
Preferably, the pH value is slightly alkaline, which means ph=7.4 to 8.
Preferably, the weak acidity of the pH value means that ph=6 to 7.
The reactive dye is selected from a trisazo benzene type or vinyl sulfone type reactive dye.
The disperse dye is selected from azo type or anthraquinone type disperse dye.
(6) Washing with water and soaping;
(7) And (3) drying: putting the fiber fabric subjected to fixation into a dryer for drying treatment;
further, the invention also provides a preparation method of the amphoteric polymer, which comprises the following steps:
s1, dispersing Chitosan (CS) in a methanol aqueous solution, heating to 50 ℃, beginning to dropwise add a methanol solution of (4-formylphenyl) caprylate (FPOE), carrying out heat preservation reaction for 24, carrying out suction filtration, carrying out ethanol Soxhlet extraction for more than 48 hours, and carrying out vacuum drying to obtain CS-FPOE powder.
S2, weighing CS-FPOE, dispersing in isopropanol, heating to 70 ℃, beginning to dropwise add 2, 3-epoxypropyl trimethyl ammonium chloride aqueous solution, and carrying out heat preservation reaction for 24 hours; filtering, extracting with ethanol for more than 48h, and vacuum drying to obtain QA-CS-FPOE powder;
the cationic modifier is used for surface modification of the polyester-cotton fabric, so that the consumption of alkali and salt in the dyeing process is reduced, and as the reactive dye and the surface of the cotton fabric are both electronegative, a large amount of alkali and salt are required to be added to improve the affinity of the reactive dye and the cotton fabric in order to overcome coulomb force, but a large amount of dyeing wastewater is caused, and the stability of the disperse dye is poor under the alkaline condition, so that the polyester-cotton fabric with high dyeing rate is difficult to obtain.
The imine (Schiff base) has pH responsiveness due to the nature of a dynamic covalent bond, and the benzyl imine has good stability in a weak alkaline environment at pH due to the conjugation of a benzene ring and c=n, and undergoes hydrolysis in a weak acid environment. The pH responsiveness of imine alkali is utilized to construct an amphiphilic polymer, and disperse dye is encapsulated, so that the mutual interference of reactive dye and disperse dye is reduced under the dyeing of polyester cotton by a one-bath method. Dyeing cotton fiber under weak alkaline condition, wherein the disperse dye is encapsulated in micelle; dyeing the polyester fiber under weak acid condition, and measuring micelle breakage to release the disperse dye.
Further, in a weak acid environment, imine bonds of the amphiphilic polymer are broken to release (4-formylphenyl) caprylate, and the compound has a similar structure to that of polyester fibers, can be used as a carrier to play a role in solubilization and plasticization of the polyester, so that the dyeing temperature is reduced, and the dyeing time is shortened.
The invention has the following advantages and beneficial effects:
