Description
Technical Field
The invention relates to a disperse dye carrier dyeing method for polyester knitted fabrics, and belongs to the technical field of textile printing and dyeing.
Background
The terylene has excellent physical and chemical properties and is the most widely applied synthetic fiber variety at present. The terylene fiber has strong hydrophobicity, high crystallinity, compact structure and no specific dyeing group in molecules, and disperse dye with simple structure and relatively low molecular mass is adopted for dyeing during dyeing. The disperse dye does not contain strong hydrophilic groups such as sulfonic groups and the like, only contains weak polar groups such as hydroxyl, amino, nitro and the like, has low water solubility, and mainly exists in a dispersed state as fine particles in water during dyeing.
The disperse dye has affinity to terylene, but dye molecules are difficult to enter the inside of the fiber at normal pressure and low temperature. The terylene is thermoplastic fiber, and only when the fiber is heated to a temperature higher than the glass transition temperature, the macromolecular chain segment of the fiber moves violently, the intermolecular gap is increased, and dye molecules can enter the fiber to obtain a certain dyeing depth. Typically, the glass transition temperature of amorphous polyester is about 67 ℃, that of crystalline polyester is about 81 ℃, and that of crystalline and oriented fibers is as high as 125 ℃. The dyeing method most commonly used for knitted polyester fabrics is therefore a high-temperature high-pressure method, i.e. the temperature is raised to around 130 ℃ and the dyeing is carried out in a closed dyeing apparatus at a pressure higher than 1 atmosphere. Along with the increase of the temperature of the dye liquor, the dye-uptake rate of the dye is greatly increased, and the dye adsorption capacity is also obviously improved. The high-temperature high-pressure dyeing can obtain products with good level-dyeing property and permeability, and the high-temperature high-pressure dyeing method is suitable for various dyes, high in dye utilization rate, high in equipment requirement, long in dyeing time and low in production efficiency. In addition, under the conditions of high temperature and high pressure, the dispersion stability of the dye is reduced, and the dye particles are easy to coagulate into coarse particles or tar-like liquid drops to be adsorbed on the surface of the fabric to generate color points.
Another dyeing method of the polyester knitted fabric is a carrier dyeing method, namely, certain carriers are selected as auxiliary agents, so that the disperse dye can dye the polyester under the conditions of normal pressure and below 100 ℃. Commonly used carriers are aromatic organic compounds with simple structures, such as aromatic phenols, esters, alcohols, ketones, hydrocarbons, and the like. Most of the carriers have large smell or certain toxicity, are not easy to remove after remaining on fabrics, and are easy to reduce the stability of the dye liquor.
Disclosure of Invention
According to the invention, the polyester knitted fabric is dyed by using the environment-friendly chemical substance vanillin as a carrier and matching with the mixture of the cellulase and the pectinase, so that the dyeing effect of the polyester under the normal pressure condition of about 100 ℃ can be effectively improved.
The invention comprises the following processes:
(1) preparing disperse dye dyeing liquid, adding cellulase and pectinase accounting for 50-80% of the mass of the dye and 30-50% of the mass of the dye respectively, heating to 80 ℃, and keeping the temperature for 15 min;
(2) adding vanillin into the dye liquor, and fully and uniformly mixing the vanillin with the dye liquor, wherein the mass of the vanillin is 8-12 times of that of the dye;
(3) and (3) adjusting the pH value of the dye solution to 5.5, adding the polyester knitted fabric to be dyed, dyeing at the dyeing temperature of 100 ℃ for 40min, and then carrying out conventional post-treatment on the fabric.
Firstly, preparing disperse dye dyeing liquid according to the color requirement of dyed polyester knitted fabric, then adding cellulase and pectinase which respectively account for 50-80% of the mass of the dye and 30-50%, heating to 80 ℃, and keeping the temperature for 15min to fully compound the two enzymes together. And then adding vanillin into the dye liquor, wherein the mass of vanillin is 8-12 times of that of the dye, and fully and uniformly mixing. Vanillin is an important spice which is commonly used in the industries of food, pharmacy and the like, can help disperse dyes to diffuse into fibers at a lower temperature in the dyeing of terylene by the disperse dyes, plays a role similar to a carrier, and has less harm to human bodies than a conventional carrier. And (3) adjusting the pH value of the dye solution to 5.5, adding the polyester knitted fabric to be dyed, and carrying out conventional dyeing at the dyeing temperature of 100 ℃ for 40 min. In the dyeing process, the unique compound formed by the cellulase and the pectinase can promote the carrier effect of the vanillin on the terylene dyeing, and further promote the dyeing depth and uniformity of the disperse dye on the fabric. After dyeing is finished, the fabric is subjected to post-treatment such as conventional reduction cleaning.
