Description
Technical Field
The invention belongs to the technical field of dyeing and finishing, and relates to a dyeing and finishing process with one-bath and one-step dyeing and finishing functions.
Background
Synthetic fiber has been widely used in various garment materials due to its excellent characteristics, and has become more and more closely associated with fashion elements such as fashion, leisure, sports, and the like. Due to the characteristics of light weight, easy dyeing, high elasticity, wear resistance, tear resistance, easy finishing and the like of the synthesis, the composite fabric is widely applied to the field of outdoor sports, particularly light outdoor, such as sportswear, outdoor jacket, quick drying coat, cold protective clothing, outdoor tent, sleeping bag, climbing bag and the like. In recent years, synthetic fibers such as polyamide fibers are widely applied to ladies' underwear, various body-shaping clothes and high-grade linings, nylon directly contacts with human skin, sweat, grease and bacteria on the surface of the skin secreted in the human body can stain the polyamide fibers, and the polyamide fibers are not cleaned for a long time, so that the use of clothes and the health of the human body are directly influenced.
A study conducted by scientists has found that human skin is an "ideal home" for bacteria. Healthy human body surfaces are covered with approximately 1000 species of bacteria, and the bacteria colonizing the skin, both in number and species, reach surprising levels, far in excess of what has been previously thought. Therefore, the current fabrics need to meet the requirements of popular colors and styles and also need to meet some functional requirements. Present-day functional textiles are generally applied to textiles by after-finishing, for example by graft modification. The grafting modification is a processing method for modifying the surface of the dyed fiber, and the textile has special functional performance by combining groups with the functions of resisting ultraviolet, bacteria, flame, wrinkle and the like through coordination chemical bonds or other types of chemical bonds. The graft modification first treats the surface of the fiber to have a point of action for binding with a functional chemical, and then applies the functional finish to the textile through after-treatment. The method mainly comprises a dipping-drying method and a padding-drying method. The existing synthetic fiber textiles with various functions need to be dyed and then finished, but the dyeing and finishing process flow is long, the energy consumption of water, electricity, steam and the like is high, the pollution discharge pressure is increased, the pollution discharge cost is higher and higher, and all the synthetic fiber textiles are increasingly limited in the actual dyeing and finishing process production.
With the continuous improvement of the consumption level, the continuous rising of the enterprise cost and the increasingly prominent environmental protection pressure, the processing of the synthetic fiber textile has new requirements, and the high fastness, the energy conservation, the emission reduction and the cost control become several important concerns and technical development trends of the processing of the synthetic fiber textile. From the processing process of synthetic fiber textiles, the method is mainly embodied in the application of novel modified dye and the short-flow processing process; the wide use of more environmentally friendly functional chemicals; the utilization rate of the chemicals is improved, and the consumption and the discharge of the chemicals are reduced. However, the improved method is still two processing processes (two baths and two steps), and the processing system is still in the traditional water bath, so that the energy consumption and the sewage discharge still restrict the development of enterprises.
Disclosure of Invention
The invention aims to solve the problems in the prior art and provides a dyeing and finishing process with one-bath and one-step dyeing and finishing functions. The invention provides a dyeing and finishing process with one bath and one step in dyeing functional finishing, which is characterized in that a fiber product, a dye and a small amount of water are added into a poor solvent of a functional finishing agent for processing, so that the dyeing and finishing of synthetic fibers are realized with less water, low energy consumption, one bath and one step, and the dyeing and the antibiosis are synchronously carried out.
In order to achieve the purpose, the technical scheme adopted by the invention is as follows:
a dyeing and finishing process of dyeing and finishing functional finishing, one-bath and one-step, adding fiber products, functional finishing agent, dye and a small amount of water into a dyeing medium, heating from room temperature to a certain temperature, keeping the temperature for a period of time, removing residual liquid, adding the dyeing medium for washing, removing liquid and drying to obtain the fiber products with dyeing and functionality;
the dyeing medium is a poor solvent of the functional finishing agent;
the small amount of water is 0.2-1 time of the mass of the fiber product;
the bath ratio of the dyeing medium before the residual liquid is removed is 1: 5-30, and the bath ratio of the dyeing medium added after the residual liquid is removed is 1: 5-30.
As a preferred technical scheme:

The glass transition temperature of the chemical fiber is generally 60-80 ℃, the molecular chain segment of the fiber is not opened when the temperature is 80 ℃, the dye is difficult to diffuse into the fiber, and the temperature can be raised quickly, so that the level-dyeing property of dyeing and functional finishing is not influenced; after the temperature reaches 80 ℃, the temperature is raised slowly, otherwise, the diffusion rate of the dye and the finishing agent is too fast, and the uniformity of dyeing and finishing is influenced. The dyeing and finishing need a certain time to reach balance, the heat preservation time is 20-120 min after the temperature is raised to a certain temperature, and the heat preservation time is less than 20min, and the dyeing and finishing do not reach balance.
The dyeing function finishing one-bath one-step dyeing and finishing process comprises the steps of adding the dyeing medium, washing for 10-30 min at the temperature of 40-80 ℃ after adding the dyeing medium, and washing for 10-30 min at the temperature of 30-50 ℃. The first relatively high spot temperature is to wash off the surface of the fibre with the loose colour and finish not diffused into the fibre, at which time most of the loose colour and finish on the surface of the fibre have been removed, and the subsequent relatively low spot temperature wash is to ensure a good fastness wash, at which time a small amount of loose colour and finish is washed off.
The dyeing and finishing process with one dyeing function and one bath and one step adopts a centrifugal, vacuum pumping or pressurizing water squeezing mode for liquid removal, and the drying temperature is 80-120 ℃.
The dyeing function finishing one-bath one-step dyeing and finishing process is characterized in that the fiber product is synthetic fiber or a textile thereof;
the dye is a disperse dye, an acid dye, a cationic dye, a vat dye or a sulphur dye.
The dyeing function finishing one-bath one-step dyeing and finishing process is characterized in that the synthetic fibers are more than one of polyester fibers, polyamide fibers, polypropylene fibers and polyacrylonitrile fibers.
According to the dyeing and finishing one-bath one-step dyeing and finishing process, the dye is used in an amount of 0.2-10% of the mass of the fiber product, and the functional finishing agent is used in an amount of 0.1-20% of the mass of the fiber product.

The dyeing functional finishing one-bath one-step dyeing and finishing process comprises the steps of dyeing, finishing.
The dyeing function finishing one-bath one-step dyeing and finishing process comprises the steps that the antibacterial agent is more than one of quaternary ammonium salt, phenol compounds, chitosan, sorbic acid and dopamine;
the antistatic agent is quaternary ammonium salt, sulfate, phosphate or polyethylene glycol diacrylate;
the flame retardant is a brominated flame retardant, a phosphorus-nitrogen flame retardant, a nitrogen flame retardant, antimony trioxide, magnesium hydroxide, aluminum hydroxide or a silicon flame retardant;
the softening agent is quaternary ammonium salt, succinate sulfonate, higher fatty alcohol, higher fatty acid ester or hydrophilic organic silicon;
the ultraviolet-resistant finishing agent is a benzotriazole compound, a nano titanium dioxide crystal, p-octyl phenyl salicylate, bisphenol disalicylate, N-di-N-butyl dithiocarbamate nickel or benzophenone;
the anti-wrinkle finishing agent is dimethylol ethylene urea, 1,2,3, 4-butane tetracarboxylic acid, citric acid or maleic acid polymer; the maleic acid polymer is generally prepared by using maleic anhydride as a raw material, hydrolyzing the maleic anhydride under an alkaline condition to generate maleic acid, and then polymerizing under the initiation action of peroxide to generate a polymer with the following structural formula:
the anti-pilling finishing agent is water-based acrylate copolymer, carboxyl or hydroxyl modified polyethylene microemulsion, polyether modified organic silicon or higher fatty acid ester.
The principle of the invention is as follows:
compared with the traditional synthetic fiber textile dyeing and antibacterial method, the synthetic fiber dyeing function finishing one-bath one-step dyeing and finishing process does not need separate dyeing and function finishing processes, once the synthetic fiber textile is added into a dyeing medium with low surface tension, the dyeing medium can be quickly spread and diffused on the fiber surface, and meanwhile, the functional finishing agent is driven to be absorbed and permeated on the fiber surface. Since the dyeing medium is a poor solvent for the functional finish, i.e., the functional finish cannot be dissolved in the dyeing medium, the functional finish dispersed in the dyeing medium brings the functional finish to the fiber as the dyeing medium moves during the dyeing process. Because the water in the dyeing system is little and can be completely absorbed by the synthetic fiber textile, the functional finishing agent can be quickly dyed on the surface of the synthetic fiber with high adsorption capacity, so that the dyeing and the functionalization of the synthetic fiber are simultaneously carried out, the time of dyeing and functional finishing is reduced to 1.2 hours from the original 3 hours, the processing time is greatly shortened, and the energy consumption and the sewage discharge in the processing process are reduced. The process realizes the one-bath one-step processing of dyeing and functionalization, the dyed synthetic fiber does not need special treatment, and the color fastness and the functional performance meet the national standard of detection.
Has the advantages that:
(1) the process of the invention has low water consumption, and can save water by 95 percent compared with the traditional synthetic fiber dyeing, so the method has less waste water and is green and environment-friendly;
(2) in the dyeing process, one bath of dyeing and functional finishing is carried out, so that the dyeing and processing finishing time is greatly reduced, and the energy consumption can be reduced by 50%;
(3) the selected medium is nontoxic, odorless and degradable, and can be recycled through simple standing separation after one-bath one-step processing of dyeing and functionalization is finished.
