Description
The technical field is as follows:
the invention relates to the technical field of textile dyeing, in particular to a dyeing process of an antibacterial bacteriostatic terylene fabric.
Background art:
polyester fiber, commonly called as terylene and abbreviated as PET fiber, belongs to a macromolecular compound, and is synthetic fiber obtained by spinning polyester formed by polycondensation of organic dibasic acid and dihydric alcohol. The polyester fiber has the advantages of good crease resistance and shape retention, high strength and elastic recovery capability.
In the processing process of the fabric, in order to endow the fabric with a certain antibacterial and bacteriostatic effect, the fabric needs to be subjected to after-treatment by adopting an antibacterial and bacteriostatic agent. The post-finishing method usually adopts a physical method and a chemical method, wherein the physical method has the problem of poor adhesion of the antibacterial bacteriostatic agent on the fiber, and can not ensure the lasting antibacterial and bacteriostatic action of the fabric. In addition, in the dyeing process, due to the combination of dye molecules and fibers, the firm adhesion of the antibacterial bacteriostatic agent on the fibers can be influenced to a certain extent, so that the antibacterial and bacteriostatic effects of the fabric are reduced.
The invention content is as follows:
the technical problem to be solved by the invention is to provide a dyeing process of antibacterial bacteriostatic polyester fabric, which can simultaneously carry out dyeing and antibacterial finishing, not only reduce processing procedures, but also ensure the dyeing effect and antibacterial effect of the fabric.
The technical problem to be solved by the invention is realized by adopting the following technical scheme:
a dyeing process of antibacterial bacteriostatic polyester fabric comprises the following operation steps:
(1) preparing a dye solution: adding disperse dye, dispersant and 3- (2-chlorphenyl) -5-methyl-4-isoxazole carboxylic acid into water to obtain dye liquor;
(2) dyeing: soaking the fabric in the dye liquor prepared in the step (1), controlling the bath ratio, starting heating, carrying out heat preservation dyeing, dropwise adding alkali liquor in the dyeing process to control the pH value of the dye liquor to be 7-8, discharging residual dyeing liquor, washing with water, carrying out reduction washing, and washing with water;
(3) and (3) fixation: and (3) soaking the fabric dyed in the step (2) in a color fixing solution, heating the color fixing solution and preserving heat, discharging color fixing residual liquid, drying, washing and drying again.
The concentration of the disperse dye is 0.5-5% owf, the concentration of the dispersant is 5-20g/L, and the concentration of the 3- (2-chlorphenyl) -5-methyl-4-isoxazole carboxylic acid is 10-40 g/L.
The dispersant is one of peregal O, OP-10 and JFC. The addition of the dispersing agent can promote the uniform dispersion of the disperse dye in the dye liquor and simultaneously play a role in level dyeing.
The bath ratio is 1: 15-30.
The heat preservation temperature of the dyeing is 80-100 ℃, and the heat preservation time is 60-120 min.
The alkali liquor is sodium hydroxide aqueous solution with the concentration of 10-20 wt%.
The temperature of the reduction cleaning is 60-80 ℃, and the time is 10-20 min.
The solution for reduction cleaning is prepared from 2-5g/L sodium hydroxide2-5g/L sodium hydrosulfite NaS2O3Prepared by the method, and the bath ratio is 1: 30-50.
The color fixing solution is prepared by adding water into diallyl dimethyl ammonium chloride and a water-soluble azo initiator, wherein the concentration of the diallyl dimethyl ammonium chloride is 10-30g/L, and the dosage of the water-soluble azo initiator is 0.2-0.5% of the mass of the diallyl dimethyl ammonium chloride.
The heat preservation temperature of the color fixing liquid is 60-80 ℃, and the color fixing time is 15-30 min.
The drying temperature is 80-100 ℃.
According to the invention, hydroxyl contained in a polyester molecular structure reacts with a chlorine substituent contained in a 3- (2-chlorphenyl) -5-methyl-4-isoxazole carboxylic acid structure, phenyl isoxazole carboxylic acid groups are grafted on polyester fiber molecules, and the groups are introduced into the polyester fiber molecules to endow the polyester with a certain antibacterial and bacteriostatic effect.
The polyester fiber is subjected to antibacterial modification simultaneously in the dyeing process, wherein the dropping of the alkali liquor can not only adjust the pH value of the dyeing solution, but also immediately neutralize hydrogen chloride generated by the reaction of 3- (2-chlorphenyl) -5-methyl-4-isoxazole carboxylic acid and hydroxyl, so that the processing procedure of the fabric is reduced, and the adhesion of an antibacterial group on the polyester fiber can be further strengthened by utilizing the color fixing effect of a color fixing agent on the dye in the subsequent color fixing procedure.
In the heating process, the color fixing agent forms a layer of polymer protective film with certain strength on the surface of the fiber through polymerization reaction, and the fiber is coated with the dye, so that the dye is not easy to fall off, and the color fastness of the fabric is improved; meanwhile, the polyester fiber can be coated with the antibacterial group, so that the grafting stability of the antibacterial group on the polyester fiber is further improved.
Diallyldimethylammonium chloride is a commonly used substance known in the art for the preparation of dye fixatives, but the resulting polymers are readily soluble in water and therefore have limited fixing properties. In order to further ensure the color fixing effect, the invention also uses N-propylene oxy phthalimide to replace diallyl dimethyl ammonium chloride to prepare the color fixing agent, and obtains better color fixing effect. That is to say, the technical problem to be solved by the present invention can also be realized by the following technical solutions, and the only difference from the above technical solutions is as follows:
the color fixing solution is prepared by adding water into N-propylene oxy phthalimide and a water-soluble azo initiator, wherein the concentration of the N-propylene oxy phthalimide is 10-30g/L, and the dosage of the water-soluble azo initiator is 0.2-0.5 percent of the mass of the N-propylene oxy phthalimide.
The invention has the beneficial effects that: the invention also realizes the antibacterial finishing of the fabric while dyeing the fabric, endows the polyester fabric with certain antibacterial performance through the dyeing process, thereby preparing the antibacterial bacteriostatic polyester fabric, further improves the antibacterial stability of the fabric by utilizing the color fixing operation in the dyeing process, and ensures the dyeing effect and the antibacterial effect of the fabric while reducing the processing procedures, thereby enabling the dyeing process to be more suitable for industrial production.
The specific implementation mode is as follows:
