Description
Technical Field
The application relates to the technical field of denim processing, in particular to a finishing processing method of antibacterial denim ready-made clothes.
Background
The antibacterial finishing of jeans garments belongs to a finishing stage after finishing the garments, and is usually carried out by adding antibacterial finishing liquid into a washing machine after finishing the washing stage, dewatering to a certain liquid carrying rate after washing the jeans garments for a certain time, and drying. However, the traditional finishing stage of jeans has the following disadvantages:
disadvantage 1: the process time is long, the production efficiency is low, the quality of the ready-made clothes is influenced, and the appearance change of the washing water of the ready-made clothes is large: the traditional jean washing machine adopts a structural design for promoting the wear of clothes, and the soaking method needs to be operated for at least 30 minutes at a temperature of between 40 and 80 ℃ after the antibacterial finishing liquid is added, so that the wear degree and the fading problem of jean can be increased, and the quality and the appearance effect of the finished clothes are further affected.
Disadvantage 2: the antibacterial finishing liquid has low exhaustion rate, serious waste and high cost: because of the first disadvantage, the water-washing plant usually adopts a method of soaking the washing machine at a low temperature for a short time, so that the exhaustion rate is low, the dosage of the antibacterial finishing liquid is increased, a large amount of antibacterial finishing liquid still remains in water, and a large amount of finishing liquid is wasted after dehydration.
Disadvantage 3: influence the sewage treatment system of the water washing plant: as most of sewage treatment systems of the water washing plants adopt a bacterial method (coordination of anaerobic bacteria and aerobic bacteria) to remove COD of sewage, the silver ion antibacterial finishing agent generated in the dipping method has broad-spectrum antibacterial property, and can inhibit and kill bacteria of the sewage plants, thereby having adverse effects on the sewage treatment systems.
Disadvantage 4: the water consumption is large, and the energy consumption is high: the high bath ratio of the dipping method consumes a large amount of water and energy, and particularly, the conventional horizontal washing water equipment needs a bath ratio of about 1:10, and correspondingly, a large amount of chemical industry and energy consumption are needed.
Disclosure of Invention
The application aims to provide a finishing processing method for antibacterial jeans wear. The application can reduce water consumption and chemical additives, is safe and environment-friendly, and can ensure that the jean garment has good effects of resisting bacteria, fixing color, washing, leveling and resisting wrinkles.
The technical scheme of the application is as follows: an antibacterial jean garment after-finishing processing method comprises the following steps:
a. pretreatment of jean garment, which is used for fixation or residue removal;
b. preparing finishing liquid, and preparing finishing liquid with the same weight according to the weight of the jean garment at normal temperature and normal pressure; each liter of the finishing liquid comprises 15-25 g of nonionic foaming agent, 1-5 g of silver ion antibacterial agent, 1-5 g of softening agent and the balance of water;
c. adding the finishing liquid into a foam machine, introducing the beaten foam into a washing machine by using the foam machine, and driving the jean garment to uniformly contact the foam by forward and reverse rotation of the washing machine for 3-8 minutes;
d. and (5) drying by cold air.
According to the after-finishing processing method of the antibacterial jean garment, the pretreatment of the jean garment comprises fixation treatment of dark jean: putting the jean ready-made clothes into a washing machine, adding a color fixing agent to submerge the jean ready-made clothes, turning the washing machine for 3-8 minutes, then soaking for 3-8 minutes, and finally dehydrating and drying.
According to the after-finishing processing method of the antibacterial jeans, each liter of the color fixing agent comprises 5-15 g of cationic modifier, 5-15 g of wet rubbing fastness improver, 0.5-1.5g of glacial acetic acid and the balance of water.
According to the after-finishing processing method of the antibacterial jeans, each liter of the color fixing agent comprises 10 grams of cationic modifier, 10 grams of wet rubbing fastness improver, 1 gram of glacial acetic acid and the balance of water.
The pretreatment of the antibacterial jean garment comprises the treatment of removing residues of light-colored jean: adding soaping agent to submerge the jean, treating at 50-70deg.C for 10-20 min, draining, adding glacial acetic acid 1-3g/L to submerge the jean, treating for 1-5 min, draining, washing with cold water for 2-5 min, dewatering, and oven drying.
According to the after-finishing processing method of the antibacterial jean garment, each liter of the soaping agent comprises 1-5 g of sodium carbonate, 0.5-1.5g of surfactant and 1-3g of hydrogen peroxide.
According to the after-finishing processing method of the antibacterial jean garment, each liter of the soaping agent comprises 3g of sodium carbonate, 1g of the surfactant and 2g of the hydrogen peroxide.
According to the after-finishing processing method of the antibacterial jean garment, each liter of finishing liquid comprises 20 grams of nonionic foaming agent, 2 grams of silver ion antibacterial agent, 3 grams of softener and the balance of water.
Compared with the prior art, the foam finishing method has the advantages that the mixed solution of the silver ion antibacterial agent, the nonionic foaming agent and the softening agent is stirred and pressurized by using a foam machine to form unstable foam, the unstable foam is then applied to the jean, the jean is driven by forward and reverse rotation of the washing machine to uniformly contact the foam, and then cold air drying treatment is carried out. Because denim fabric has the characteristics of weak dyeing and core impermeability due to poor affinity of indigo dye fibers, unique abrasion appearance and hand feeling are required to be endowed to the surface of the finished garment through a washing process after sewing, and therefore, the denim fabric is usually finished by working after washing water processing of the denim fabric is finished. Therefore, the method of the application can lead the jean garment to have good antibacterial, color-fixing, washing-resistant, leveling and crease-resistant effects. The foam finishing process solves the problem of large water and chemical consumption in the impregnation method, and can achieve the following steps of 1:1, the utilization rate of the chemical auxiliary reaches about 90 percent, and the water consumption of 90 percent and the chemical auxiliary consumption of 60 percent are reduced. The application relates to a low-liquid-supply high-energy-saving processing method, which reduces water consumption and chemical additives, and is safe and environment-friendly.
The silver ion antibacterial agent is adopted, and the silver ion antibacterial agent has the advantages of safety, broad spectrum, long-acting property, no bacteria resistance and remarkable antibacterial effect, and is an ideal antibacterial agent. Since the durability of the antimicrobial treatment effect is dependent on the material being treated, it is desirable that the material be completely free of impurities and residual adjuvants (e.g., brighteners, surfactants, unfixed dyes, sulfate ions, sulfide ions, etc.). In order to obtain the best effect, the jean is pretreated by the following method, and the properties of the jean with dark colors and light colors are pretreated: for dark-colored washed denim, the color fastness is poor, the wet friction is only 1-2 grade, so the dark-colored denim needs to be subjected to fixation treatment before antibacterial finishing to improve the color fastness, and for medium-light-colored washed denim, a large amount of oxidants such as sodium hypochlorite and potassium permanganate are used for color shifting, and then reducing agents such as sodium thiosulfate and sodium metabisulfite are used for neutralizing the oxidants, so the medium-light-colored denim needs to be subjected to soaping treatment to remove residual auxiliary agents before antibacterial finishing, thereby the best antibacterial treatment effect is achieved, and meanwhile, the chemical auxiliary agent utilization rate of the application is high to about 90%, so the rest small amount of silver ions can be subjected to reaction precipitation by sulfate ions in sewage of a water washing plant, and the method is safe and environment-friendly.

In order to verify the technical effects of the scheme of the application, the applicant performs scanning electron microscope image observation on the jean ready-made clothes before being treated and the jean ready-made clothes in the embodiment 1 of the application to respectively obtain an electron microscope image of the jean ready-made clothes before being treated shown in fig. 1 and an electron microscope image of the jean ready-made clothes in the embodiment 1 of the application shown in fig. 2. As can be seen from fig. 1 and fig. 2, the fiber surface of the jean garment treated by the method is attached with solid particles, which indicates that the fiber surface of the jean garment treated by the method is attached with silver ion antibacterial agent, and meanwhile, as can be seen from fig. 2, the fiber surface of the jean garment treated by the method is compactly arranged, which indicates that the jean garment treated by the method has good washing, flattening and crease-resistant effects. The foam finishing method comprises the steps of stirring and pressurizing a mixed solution of a silver ion antibacterial agent, a nonionic foaming agent and a softening agent by using a foam machine to form unstable foam, then applying the unstable foam to the jean, driving the jean to uniformly contact the foam by using the forward and reverse rotation of a washing machine, and then drying by using cold air. Because denim fabric has the characteristics of weak dyeing and core impermeability due to poor affinity of indigo dye fibers, unique abrasion appearance and hand feeling are required to be endowed to the surface of the finished garment through a washing process after sewing, and therefore, the denim fabric is usually finished by working after washing water processing of the denim fabric is finished. Therefore, the method of the application can lead the jean garment to have good antibacterial, color-fixing, washing-resistant, leveling and crease-resistant effects. The foam finishing process solves the problem of large water and chemical consumption in the impregnation method, and can achieve the following steps of 1:1, the utilization rate of the chemical auxiliary reaches about 90 percent, and the water consumption of 90 percent and the chemical auxiliary consumption of 60 percent are reduced. The application relates to a low-liquid-supply high-energy-saving processing method, which reduces water consumption and chemical additives, and is safe and environment-friendly.
Further, in order to verify the antibacterial property of the jean garment of the present application, the applicant selected glucose aureofaciens for antibacterial analysis of the jean garment. The applicant selected the untreated jeans, the jeans of example 2, and the jeans of example 4 for the experiments. The mixture was left for 12 hours under the same infection conditions, and the infection of the glucose bacteria was observed. The results are shown in FIGS. 3-5, respectively. Fig. 3 is an infection view of the jeans wear before the treatment, fig. 4 is an infection view of the jeans wear in example 2, and fig. 5 is an infection view of the jeans wear in example 4. As can be seen from FIGS. 3 to 5, the jean garment treated in the present application has excellent antibacterial ability, and a large amount of glucose-gold bacteria is not seen around the jean garment, while a large amount of glucose-gold bacteria is grown around the jean garment before the treatment. The silver ion antibacterial agent is adopted, and the silver ion antibacterial agent has the advantages of safety, broad spectrum, long-acting property, no bacteria resistance and remarkable antibacterial effect, and is an ideal antibacterial agent. Since the durability of the antimicrobial treatment effect is dependent on the material being treated, it is desirable that the material be completely free of impurities and residual adjuvants (e.g., brighteners, surfactants, unfixed dyes, sulfate ions, sulfide ions, etc.). In order to obtain the best effect, the jean is pretreated by the following method, and the properties of the jean with dark colors and light colors are pretreated: for dark-colored washed denim, the color fastness is poor, the wet friction is only 1-2 grade, so the dark-colored denim needs to be subjected to fixation treatment before antibacterial finishing to improve the color fastness, and for medium-light-colored washed denim, a large amount of oxidants such as sodium hypochlorite and potassium permanganate are used for color shifting, and then reducing agents such as sodium thiosulfate and sodium metabisulfite are used for neutralizing the oxidants, so the medium-light-colored denim needs to be subjected to soaping treatment to remove residual auxiliary agents before antibacterial finishing, thereby the best antibacterial treatment effect is achieved, and meanwhile, the chemical auxiliary agent utilization rate of the application is high to about 90%, so the rest small amount of silver ions can be subjected to reaction precipitation by sulfate ions in sewage of a water washing plant, and the method is safe and environment-friendly.
Further, the applicant conducted an antibacterial test for a long period of time on the jeans garments of example 2, example 4, example 5 and example 6. The cells were allowed to stand under the same infection conditions for 10 days, and the infection of the glucose bacteria was observed, and the results are shown in FIGS. 6 to 9, respectively. Fig. 6 is an infection view of the jean garment in example 2, fig. 7 is an infection view of the jean garment in example 4, fig. 8 is an infection view of the jean garment in example 5, and fig. 9 is an infection view of the jean garment in example 6. It is clear from a comparison of examples 2 and 5, examples 6 and 9 that the components of the finishing liquid and the rotating process of the washing machine preferred in examples 5 and 6 of the present application can achieve an antibacterial effect for a long period of time. The ozone is introduced into the washing machine in the forward and reverse rotation process, and can be used as gas to drive the foam to continuously form an unstable state, so that the jean garment is convenient to contact with the unstable foam, the finishing liquid is adsorbed, and meanwhile, the ozone also has good sterilization and disinfection capability, and can be used for sterilizing and disinfecting in cooperation with the silver ion antibacterial agent. In addition, the dithiophene ethylene is added into the finishing liquid, so that the dithiophene ethylene can be well adhered to the jeans, meanwhile, the dithiophene ethylene has a good light response group, and can form a nano-tube-shaped microstructure under the irradiation of ultraviolet rays with specific wavelength, so that when ozone reacts with silver ions to form silver oxide, the structure can be used as an adsorption point for adsorbing ozone molecules and the silver oxide, on one hand, the silver ions can be adsorbed and reserved on the jeans for a long time, the long-time sterilizing effect of the silver ions is provided, on the other hand, the adsorbed ozone can be slowly released, the secondary sterilizing effect of the ozone is formed, the long-time antibacterial capability is formed by matching with the silver ions, and meanwhile, the application adopts a cold air drying mode, so that the ozone decomposition of the adsorption is accelerated in a drying mode, and the antibacterial time and the antibacterial effect of the jeans are greatly improved.
In conclusion, the application can reduce the water consumption and the chemical auxiliary agent, is safe and environment-friendly, and can ensure that the jean garment has good effects of resisting bacteria, fixing color, washing, leveling and resisting wrinkles.
