Technical Field

[0001] The invention relates to the technical field of textiles, and in particular to a method for continuous environmentally friendly dyeing of a nylon cellulose fiber ribbon with antibacterial function. Background Art

[0002] Nylon cellulose fiber webbing is widely used in the textile field, but traditional dyeing methods have many shortcomings. High energy consumption and large amount of chemical additives used lead to serious environmental pollution. It is difficult to take into account the dyeing effects of nylon and cellulose fibers at the same time, resulting in poor dyeing fastness and difficulty in color control. There is also a lack of effective means to give the webbing antibacterial function, which cannot meet the market demand for functional textiles.

[0003] Chinese patent document CN118932755A discloses a continuous environmentally friendly dyeing method for nylon cellulose fiber ribbons with antibacterial function, wherein the nylon cellulose fiber ribbons are dyed with reactive dyes and acid dyes, and the dyeing method includes a cationic modification stage of the cellulose fiber and a dyeing stage of the nylon cellulose fiber ribbons; the cationic modification stage of the cellulose fiber is to impregnate the ribbon with a cationic modifier, and then successively impregnate the anionic auxiliary agent, and dye the nylon with a mixed dyeing solution of glacial acetic acid, acid dyes, and reactive dyes, and finally impregnate the alkali solution, steam, and complete the dyeing of the cellulose fiber. The above scheme realizes the continuous dyeing of the nylon cellulose fiber ribbons with reactive dyes and acid dyes by cationic modification and temporary blocking of cationic groups with anionic auxiliary agents, and by screening dyeing auxiliary agents, which is environmentally friendly and efficient, and the fabric has obtained certain antibacterial properties, but the above patent still has the following defects:

[0004] During the implementation of the above patent, since natural and biological agents are not used or used less, the document may rely on more traditional chemical auxiliaries, which will increase the risk of chemical residues in the dyeing process, which not only affects the environmental performance of the fabric, but may also irritate human skin during wearing. In addition, the above patent does not clarify the specific composition and safety of the antibacterial agent. If chemical synthetic antibacterial agents are used, it may cause health problems such as allergic reactions during long-term use or contact with the human body. Summary of the invention

BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Figure 1 It is a flow chart of the present invention. DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0030] See also Figure 1 As shown, a continuous environmentally friendly dyeing method for nylon cellulose fiber ribbon with antibacterial function comprises the following steps:

[0031] S1. Cleaning treatment: Place the nylon cellulose fiber ribbon in a cleaning solution for cleaning to remove impurities, oil stains and other pollutants that may be attached to the surface of the ribbon to ensure that the surface of the ribbon achieves a good cleaning effect. The cleaning solution can be a water-based solution, or a bio-based detergent that does not contain harmful substances can be selected. The ribbon after cleaning is clean and free of oil stains, providing an ideal basis for subsequent treatment.

[0032] S2, cationic modification, immersing the cleaned ribbon in a cationic modifier treatment solution, and the surface of the ribbon is cationically modified by dipping and rolling. The cationic modifier has the functions of improving the adhesion of the ribbon dye and increasing the antibacterial agent loading amount. The cationic modifier can be an environmentally friendly, low-toxic chemical, such as quaternary ammonium salts, amine compounds, etc.

[0033] S3. Antimicrobial loading: The antimicrobial solution is impregnated on the cationic modified ribbon to effectively load the antimicrobial agent on the ribbon surface. The antimicrobial agent can be silver ions, copper ions, natural plant extracts or other natural or synthetic chemicals with long-term antimicrobial effects. The loading amount of the antimicrobial agent should be controlled within a certain range to ensure that the antimicrobial properties of the ribbon and the comfort of the fiber are not affected.

[0034] S4, dyeing treatment, the ribbon treated with antimicrobial agent loading is dipped into mixed dye solution, the dye solution is mixed with reactive dye and acid dye in a certain proportion, and the dyeing process is carried out at room temperature or low temperature to reduce energy consumption and reduce environmental pollution. Reactive dye is mainly used to improve the color fastness of the ribbon, and acid dye is used to enhance the color brightness and layering of the ribbon. Through padding and dyeing treatment for an appropriate time, the ribbon is dyed evenly and brightly.

[0035] S5. Steaming color fixation: The dyed ribbon is steamed to promote a stronger combination of dye molecules and cellulose fibers, thereby improving the color fastness of the dyeing. The steaming temperature, time and steam pressure are all controlled within a suitable range, which can not only ensure the color fixation effect, but also save energy consumption. Steaming treatment also helps to improve the softness of the ribbon.

[0036] S6, water washing and soap washing, the ribbon after color fixing is washed with water and soap washing to remove unbound dyes, antibacterial agents and other additives to ensure the cleanliness and comfort of the ribbon. Warm or cold water is used for water washing, and the waste of water resources is reduced through an efficient water circulation system. Natural plant-based soaping agents are used for soap washing, which not only has a strong decontamination effect, but also will not pollute the water source.

[0037] S7, softening and drying. The ribbons that have been washed and soaped are softened to enhance the feel and flexibility of the ribbons. Natural plant-based softeners are used as softening agents, which can not only improve the softness of the ribbons but also have no negative impact on the environment. After finishing, the ribbons are dehydrated and then dried using energy-saving drying equipment. The drying process uses heat pump drying technology to recover waste heat to reduce energy consumption.

[0038] The cleaning treatment is to put the ribbon into an aqueous solution containing 2-5g / L non-ionic surfactant, soak it at 40-50℃ for 10-15 minutes, then rinse it with clean water and dehydrate it. The non-ionic surfactant is fatty alcohol polyoxyethylene ether;

[0039] Using an aqueous solution containing 2 to 5 g / L of non-ionic surfactant for cleaning and soaking at 40 to 50°C for 10 to 15 minutes can effectively remove oil and impurities on the surface of the ribbon. The mild nature of the non-ionic surfactant can avoid damage to the ribbon fibers and has a good decontamination effect, ensuring that the ribbon surface remains clean and providing a better attachment basis for subsequent cationic modification and antibacterial agent loading. Warm water soaking and appropriate cleaning time can also enhance the penetration of the surfactant and improve the cleaning efficiency without affecting the overall quality of the ribbon.

[0040] The formula of the padding solution for cationic modification treatment is: 8-12 g / L of cationic modifier, 0.3-0.8 g / L of penetrant, the treatment temperature is 45-55° C., the liquid carrying rate is controlled at 50%-60%, the cationic modifier is chitosan quaternary ammonium salt, and the penetrant is alkylphenol polyoxyethylene ether;

[0041] The cationic modification treatment design uses chitosan quaternary ammonium salt as a cationic modifier, which can effectively give the ribbon good cationic properties and improve its antibacterial, wear resistance and softness; the addition of penetrant alkylphenol polyoxyethylene ether helps to improve the permeability of the treatment liquid, so that the cationic modifier can penetrate into the ribbon fiber more evenly and deeply, and control the temperature within the range of 45-55°C, which helps to accelerate the reaction and improve the treatment efficiency. The appropriate liquid carrying rate of 50% to 60% ensures the full adhesion of the modifier, while avoiding excessive waste of liquid, optimizing the process effect and cost control.

[0042] The formula of the antibacterial agent solution is: 0.5-1.5 g / L of nano-silver antibacterial agent, 0.2-0.6 g / L of dispersant, the temperature is 30-40° C., the liquid carrying rate is 50%-60%, and the dispersant is sodium polyacrylate;

[0043] The design of the antibacterial solution effectively provides a lasting antibacterial effect by using nano-silver antibacterial agent, can inhibit the growth of bacteria and fungi, and improve the hygienic performance of the ribbon. The addition of dispersant sodium polyacrylate can effectively disperse the nano-silver particles to prevent them from aggregating, and ensure the uniform distribution of the nano-silver in the solution, thereby improving the activity and uniformity of the antibacterial agent. Controlling the processing temperature within the range of 30-40°C helps to improve the stability of the solution and the stable dispersion of the nano-silver particles and avoid particle precipitation. At the same time, a liquid carrying rate of 50% to 60% can ensure that the antibacterial agent fully infiltrates the ribbon to achieve an ideal antibacterial effect.

[0044] The formula of the mixed dye solution is: 3-8 g / L of active dye, 2-6 g / L of acid dye, 1-3 g / L of auxiliary dye, the pH value of the dye solution is adjusted to 4-6 with a pH value regulator, the liquid carrying rate is 50%-60%, the active dye is a vinyl sulfone type active dye, the acid dye is an anthraquinone acid dye, the auxiliary dye is sodium sulfate, and the pH value regulator is acetic acid;

[0045] The mixed dye solution formula design can provide bright and lasting color effects by reasonably combining vinyl sulfone type reactive dyes and anthraquinone type acid dyes, and has both high fastness and depth of dyes. The covalent bonding between the reactive dyes and the fibers ensures the durability of the dyeing effect, while the acid dyes enhance the brightness of the colors. Sodium sulfate, as a dyeing aid, can effectively reduce the viscosity of the dye solution, improve the permeability of the dye in the fiber, and ensure uniform dyeing. The pH value of the dye solution is adjusted to the range of 4 to 6 with acetic acid, which can optimize the adsorption of the dye and avoid dye degradation, while ensuring the best dyeing effect. Controlling the liquid carrying rate of 50% to 60% can not only ensure the full penetration of the dye solution, but also avoid waste, thereby improving dyeing efficiency and cost-effectiveness.

[0046] The steam fixation temperature is set at 100-110°C and the steaming time is 3-5 minutes, which helps to ensure sufficient reaction between the dye and the fiber and a more solid fixation effect. Appropriate temperature and time can promote the stability of the molecular structure of the dye, enhance color fastness, and prevent the dye from falling off or fading. At the same time, this temperature range is relatively mild, which can effectively avoid damage or deformation to the fabric, maintain the texture and color uniformity of the fabric, and improve the dyeing quality and production efficiency.

[0047] In the design of soaping solution, sodium polyoxyethylene fatty alcohol ether sulfate is used as soaping agent, which can effectively remove unfixed dyes, stains and impurities on the fabric to ensure cleanliness after dyeing. The temperature range of 60-70°C and the soaping time of 10-15 minutes are set to ensure that the soaping agent can fully exert its decontamination effect under mild conditions while avoiding damage to the fabric by high temperature. Appropriate soaping agent concentration and time setting can help improve soaping efficiency, ensure the cleanness of the fabric surface and bright color, and improve the quality after dyeing and the service life of textiles.

[0048] In the design of softening finishing liquid, the use of silicone softener can effectively improve the softness, smoothness and comfort of the fabric, while giving the fabric excellent feel and flexibility. The softener concentration of 3-6g / L and the temperature setting of 30-40℃ allow the softener to penetrate into the fiber evenly under milder conditions to avoid damage or excessive treatment of the fabric. The treatment time of 10-15 minutes can ensure that the softener can fully play its role, improve the antistatic properties, durability and comfort of the fabric, and ultimately improve the overall quality and wearing experience of the fabric.

[0049] Choosing a variety of cellulose fibers or single fibers such as cotton, linen, viscose, modal, lyocell, etc. as raw materials can comprehensively utilize the advantages of different fibers and improve the overall performance of the fabric. Cotton fiber provides natural softness, moisture absorption and breathability, linen fiber increases the strength and antibacterial properties of the fabric, viscose and modal provide better gloss and softness, and lyocell has higher environmental protection and stronger durability. By mixing these fibers, fabrics with multiple functions can be obtained, which improve comfort, durability and market competitiveness to meet different usage needs and consumer preferences.

[0050] Finally, by adjusting the padding pressure and speed to control the liquid pick-up rate during the dyeing process, the amount of liquid absorbed by the fabric can be accurately controlled, thereby ensuring that the dye penetrates evenly into the fiber and achieving the ideal dyeing effect. The appropriate liquid pick-up rate can prevent excessive or insufficient dye, avoid uneven fabric dyeing or waste of dye. By accurately adjusting the padding pressure and speed, production efficiency can be improved, dye and water resources can be saved, and production costs can be reduced. At the same time, the quality of the fabric can be kept stable and the accuracy and consistency of dyeing can be improved.

[0073] In comparative example 1, the traditional immersion dyeing process is adopted, ordinary chemical auxiliaries are used for dyeing, and no cationic modification and antibacterial agent loading treatment are performed. The ribbon is placed in a dye solution containing reactive dyes and acid dyes, and is immersed in dyeing for a long time at high temperature, and then conventional treatments such as color fixing, water washing, and soaping are performed.

[0074] In comparative example 2, only cationic modification treatment was performed without loading antimicrobial agent, and other dyeing steps were the same as those in example 1.

[0075] In comparative example 3, no cationic modification treatment was performed, only the antibacterial agent was loaded, and the dyeing steps were the same as those in example 1.

[0076] Sample number: the identifier of the sample, divided into Example 1, Example 2, Example 3 and Comparative Example 1, Comparative Example 2, Comparative Example 3.

[0077] Test items: antibacterial performance, color fastness to rubbing and K / S value test.

[0078] Test standard number: relevant national standard number, GB / T20944.3-2008 (antibacterial properties) and GB / T3920-2008 (color fastness to rubbing).

[0080] Test results:

[0081]

[0082] Combining the data in the above table, we can draw the following conclusions:

[0083] Antibacterial performance: The samples in Example 1 and Example 3 have high antibacterial performance, and the bacteria blocking rates are all above 98%. In particular, Example 1 has a bacteria blocking rate of 99.9%, showing that its antibacterial effect is very good. The antibacterial performance of the comparative samples is poor, and the bacteria blocking rate is between 93% and 96%, which is much lower than the example samples.

[0084] Dry rubbing color fastness: Example 3 performs best, with a dry rubbing color fastness of level 5, indicating that its color fastness under dry rubbing is excellent. Example 1 and Example 2 are levels 4 and 3, respectively, and perform well. The dry rubbing color fastness of the comparative example sample is low, with the lowest being level 1, indicating that its dry rubbing color fastness is poor.

[0085] Wet rubbing color fastness: Example 3 performs better, with a wet rubbing color fastness of Level 4, which is excellent. The wet rubbing color fastness of Example 1 is Level 3, which is still acceptable. Example 2 is slightly worse, with a wet rubbing color fastness of Level 2. The wet rubbing color fastness of the comparative samples is generally poor, especially Comparative Example 3, which is Level 1, and the performance is unqualified.

[0086] K / S value test: K / S value is an indicator of color concentration. The K / S values ​​of Example 1 and Example 3 are relatively low, namely 1.2 and 1.3, respectively, indicating that their colors are lighter, while the K / S values ​​of Example 2 and the comparative sample are relatively high, namely 1.5-1.8, respectively, indicating that their colors are relatively darker.

[0088] The overall performance of the comparative samples was poor, especially in terms of color fastness to rubbing. Almost all comparative samples failed to reach the qualified level in terms of dry and wet rubbing color fastness, and their antibacterial properties were also weak.

[0089] It can be seen from the above data that the example samples are superior to the comparative example samples in durability and antibacterial performance, indicating that the quality of the example samples is more reliable and has better comprehensive performance.
