Description

Technical Field

[0001] The invention relates to the technical field of dyeing a printed mosquito net, and more specifically to a dyeing method for a printed mosquito net with high permeability. Background Art

[0002] Dyeing and printing of mosquito nets are important processes to enhance their aesthetics and market competitiveness. Through various dyeing techniques, mosquito nets can not only provide basic mosquito protection functions, but also be integrated into the home environment and become part of the decoration. In order to meet consumers' diverse needs for mosquito net colors and patterns, manufacturers use a variety of dyes and printing technologies to produce mosquito net products with attractive designs and rich colors.

[0003] However, these dyeing and printing processes currently face several technical challenges. First, conventional dyeing methods often make it difficult to ensure uniform distribution of dyes on mosquito net fibers, which directly affects the appearance and quality of the finished product. Uneven distribution of dyes may result in mottled colors, affecting the overall aesthetics. Second, traditional dyeing processes usually require large amounts of water and chemicals, which not only increases production costs but can also place a significant burden on the environment. Large-scale use of water resources and chemicals can lead to water and chemical pollution, posing a threat to the ecological environment and human health. Finding more efficient and environmentally friendly dyeing technologies has become an urgent need in the industry.

[0004] Therefore, in view of the above-mentioned technical problems, it is necessary to provide a dyeing method for a high-permeability printed mosquito net. Summary of the invention

[0005] The object of the present invention is to provide a dyeing method for a high-permeability printed mosquito net to solve the above-mentioned problems.

[0006] In order to achieve the above purpose, the technical solution provided by an embodiment of the present invention is as follows: A dyeing method for a high-permeability printed mosquito net comprises the following steps: S1: preparing a mosquito net base fabric, wherein the base fabric material is selected from polyester or nylon, and the fiber structure and density of the base fabric are predetermined to optimize the effect of subsequent dyeing and printing treatment; S2: pre-treating the base fabric to enhance its dyeing acceptance, including washing, drying and pre-wetting treatment; S3: dyeing the base fabric with a water-based dye containing magnetic particles and dyeing under the action of an external magnetic field to control the distribution and penetration of the dye; S4: Using digital printing technology, the predetermined pattern is directly printed on the dyed base fabric; S5: Post-treatment is performed, including color fixing and softening steps under the action of a magnetic field to improve the durability of the printed pattern and the feel of the base fabric.

[0007] As a further improvement of the present invention, in S3, alcohol is used to clean the magnetic particles and then dried to remove surface impurities to ensure the purity and effect of subsequent chemical treatment. At the same time, a silane coupling agent is used to treat the cleaned magnetic particles to provide active sites for chemical reactions.

[0008] As a further improvement of the present invention, the S3 further comprises surface modification of the magnetic particles, wherein the surface modification comprises coating the surface of the magnetic particles with a porous film of chemical functional groups, wherein the chemical functional groups are selected from carboxyl groups or amino groups.

[0009] As a further improvement of the present invention, in S3, the activated magnetic particles are immersed in a solution containing antibacterial and insect repellent functional compounds, which are any one of silver nanoparticles, zinc oxide, copper oxide and natural extracts, and the natural extracts include tea tree oil and peppermint extract.

[0010] As a further improvement of the present invention, the application of the magnetic field in S3 is a dynamically controllable magnetic field generated by using electromagnets in the dyeing and fixing process, which can generate magnetic fields in horizontal and vertical directions, and the magnetic field strength is adjusted according to the characteristics of the dye and the magnetic particles.

[0011] As a further improvement of the present invention, the S3 needs to be carried out under high temperature and high pressure conditions, with a specific temperature range of 130° C. to 135° C. and a pressure of 3 to 4 atmospheres.

[0012] As a further improvement of the present invention, the dyed material in S5 is slowly cooled and treated with a fixing agent to achieve color fixation.

[0013] As a further improvement of the present invention, the mosquito net material after dyeing and printing in S3 and S4 is washed with water to remove excess dye and printing paste.

[0014] As a further improvement of the present invention, the post-processing step of S5 further includes drying the dyed and printed mosquito net material at a temperature not exceeding 60°C, and using magnetic separation technology to recover magnetic particles not fixed to the base fabric during the drying process to reduce material loss and improve resource utilization efficiency.

[0015] As a further improvement of the present invention, the magnetic particles in the mosquito net are demagnetized in S5 to ensure that the dyed and printed mosquito net is not affected by the magnetic field during use, thereby maintaining its safety and comfort in use. The demagnetization of the magnetic particles in the mosquito net in S5 adopts alternating magnetic field demagnetization.

[0016] Compared with the prior art, the advantages of the present invention are: (1) The high-permeability printed mosquito net dyeing method of this scheme uses magnetic particles to enhance the distribution control and functionality of the dye, achieving more precise dyeing and pattern printing compared to the existing technology, while adding additional functions such as antibacterial and insect repellent. This method first pre-treats and functionalizes the magnetic particles so that they can not only effectively carry the dye, but also bring additional health and protection effects to the mosquito net by soaking them in a solution containing silver nanoparticles, zinc oxide, copper oxide or natural extracts such as tea tree oil and mint extract. After the mosquito net has been used for a period of time, the functionality may begin to weaken. At this time, the user can reactivate the functionality of the magnetic particles by spraying a new solution containing the same or similar functional compounds. Since the particles already have functional chemical groups that react with these compounds, they can re-adsorb new compounds, thereby restoring or enhancing the antibacterial and insect repellent properties of the mosquito net.

[0017] (2) During the dyeing process, this solution uses an externally applied dynamic controllable magnetic field to accurately control the distribution of magnetic particles and the dyes they carry on the mosquito net base fabric, thereby improving the dyeing uniformity and pattern accuracy. In addition, by using magnetic separation technology to recover unfixed magnetic particles in post-processing, material loss is reduced and resource utilization efficiency is improved. Finally, through alternating magnetic field demagnetization treatment, the safety and comfort of the dyed and printed mosquito net during use are guaranteed, avoiding interference with electronic equipment or adsorption of metal particles. Overall, this method not only improves the aesthetics and functionality of the mosquito net, but also meets the requirements of sustainable development through an environmentally friendly treatment process, making the product more competitive in the market.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0020] Embodiment 1:

[0021] See also Figure 1-2 , a dyeing method for a high-permeability printed mosquito net, comprising the following steps: S1: preparing a mosquito net base fabric, wherein the base fabric material is selected from polyester or nylon, and the fiber structure and density of the base fabric are predetermined to optimize the effect of subsequent dyeing and printing treatment; S2: pre-treating the base fabric to enhance its dyeing acceptance, including washing, drying and pre-wetting treatment; S3: dyeing the base fabric with a water-based dye containing magnetic particles and dyeing under the action of an external magnetic field to control the distribution and penetration of the dye; S4: Using digital printing technology, the predetermined pattern is directly printed on the dyed base fabric; S5: Post-treatment is performed, including color fixing and softening steps under the action of a magnetic field to improve the durability of the printed pattern and the feel of the base fabric.

[0022] In S3, alcohol is used to clean the magnetic particles and then dry them to remove surface impurities, ensuring the purity and effectiveness of subsequent chemical treatments. At the same time, a silane coupling agent is used to treat the cleaned magnetic particles to provide active sites for chemical reactions.

[0023] S3 also includes surface modification of the magnetic particles, wherein the surface modification includes coating the surface of the magnetic particles with a porous film of chemical functional groups, wherein the chemical functional groups are selected from carboxyl groups or amino groups.

[0024] In S3, the activated magnetic particles are immersed in a solution containing antibacterial and anti-insect functional compounds, which are any one of silver nanoparticles, zinc oxide, copper oxide and natural extracts, and the natural extracts include tea tree oil and peppermint extract.

[0025] The application of magnetic field in S3 is a dynamically controllable magnetic field generated by using electromagnets in the dyeing and fixing process, which can generate magnetic fields in horizontal and vertical directions, and the magnetic field strength is adjusted according to the characteristics of the dye and magnetic particles.

[0026] Among them, choosing the right base fabric is the basis of the entire dyeing and printing process. The material of the base fabric and its fiber structure and density directly affect the quality and function of the final product. Predetermining the fiber structure and density of the base fabric can optimize the absorption rate of the dye and the clarity of the printing, thereby improving the overall aesthetics and functionality of the product.

[0027] Pretreatment steps include washing, drying and pre-wetting to remove impurities from the base fabric and prevent dimensional changes during processing. These steps are essential to ensure uniform absorption of dyes and printing inks.

[0028] The dye formula specifically contains magnetic particles, whose main function is to effectively carry and control the distribution of dye particles under the action of an external magnetic field. This coating method ensures that the dye can be evenly suspended and stably present in the aqueous solution, thus avoiding precipitation or aggregation during the dyeing process.

[0029] During the dyeing process, a magnetic field of specific strength and direction is applied to precisely control the magnetic particles. The main function of the magnetic field is to adjust and fix the position of the magnetic particles (and the dye particles wrapped in them) on the mosquito net base fabric. By finely adjusting the magnetic field parameters, the magnetic particles can be evenly distributed on the entire surface of the base fabric, thereby achieving uniform distribution of the dye.

[0030] Because the magnetic particles can be evenly distributed on the base fabric under the action of the magnetic field, the dye is also evenly distributed. This uniformity of distribution is achieved by controlling the physical position of the magnetic particles, without relying on traditional liquid flow or diffusion processes, which can significantly improve the color consistency and saturation during the dyeing process.

[0031] The key to magnetic particles being able to carry dyes lies in the special treatment of their surface and their behavior in a magnetic field. These particles are usually surface-modified to enable them to adsorb or chemically bind dye molecules. The surface modification can be a chemical coupling agent, such as a silane coupling agent, which forms an active layer on the particle surface that is able to form a stable bond with the dye molecules.

[0032] The activated magnetic particles are soaked in a solution containing antibacterial and insect repellent functional compounds. These compounds can be selected from silver nanoparticles, zinc oxide, copper oxide or specific natural extracts. Silver nanoparticles: have strong antibacterial and antiviral properties and can effectively inhibit the growth of bacteria and viruses.

[0033] Zinc oxide and copper oxide: These inorganic compounds also have antibacterial properties, and copper oxide can also provide mildew and antiseptic effects. Natural extracts: Choose tea tree oil and peppermint extract. These natural substances not only have antibacterial and insect repellent effects, but also add a natural fragrance to the mosquito net, enhancing the user experience.

[0034] During the dyeing process, when these magnetic particles with dye are exposed to an external magnetic field, they respond to the guidance of the magnetic field so that the dye can be precisely transported and evenly distributed on the mosquito net base fabric. By controlling the direction and intensity of the magnetic field, the position and density of the dye on the base fabric can be precisely controlled, thereby achieving complex patterns and high-quality dyeing effects.

[0035] Softeners can be used later in the softening process. These chemicals can create additional lubrication between fibers, reduce friction between fibers, and make the fabric feel softer. Common softeners include cationic softeners, nonionic softeners, and silicone softeners. These softeners can be applied to textiles by dipping, spraying, or roller coating.

[0036] After the mosquito net has been used for a period of time, its functionality may begin to weaken. At this point, the user can reactivate the functionality of the magnetic particles by spraying a new solution containing the same or similar functional compounds. Since the particles already have functional chemical groups that react with these compounds, they can re-absorb new compounds, thereby restoring or enhancing the antibacterial and insect repellent properties of the mosquito net. The material of the base fabric makes it difficult for them to be absorbed by the base fabric material. It is necessary to select compounds that have passed safety certification, such as those approved by environmental protection agencies or public health agencies for contact with the skin or close contact with products, but it is still necessary to ensure their safety under specific uses and concentrations.

[0037] The high permeability printed mosquito net dyeing method of the above scheme uses magnetic particles to enhance the distribution control and functionality of the dye, thereby achieving more accurate dyeing and pattern printing compared with the prior art, and adding additional functions such as antibacterial and insect repellent. This method first pre-treats and functionalizes the magnetic particles so that they can not only effectively carry the dye, but also bring additional health and protection effects to the mosquito net by soaking in a solution containing silver nanoparticles, zinc oxide, copper oxide or natural extracts such as tea tree oil and mint extract. During the dyeing process, the distribution of the magnetic particles and the dyes they carry on the mosquito net base fabric is accurately controlled by using an externally applied dynamic controllable magnetic field, thereby improving the dyeing uniformity and the accuracy of the pattern. In addition, by using magnetic separation technology to recover the unfixed magnetic particles in the post-processing, the material loss is reduced and the resource utilization efficiency is improved. Finally, the safety and comfort of the mosquito net after dyeing and printing are guaranteed during use, and the problem of interference with electronic equipment or adsorption of metal particles is avoided. Overall, this method not only improves the aesthetics and functionality of the mosquito net, but also meets the requirements of sustainable development through an environmentally friendly treatment process, making the product more competitive in the market.

[0038] S3 needs to be carried out under high temperature and high pressure conditions, with the specific temperature range being 130°C to 135°C and the pressure being 3 to 4 atmospheres.

[0039] The dyed material in S5 is slowly cooled and treated with a fixative to fix the color.

[0040] During color fixing, the magnetic field helps the magnetic particles (and the dyes they carry) to be precisely positioned and fixed at specific locations on the base fabric. This positioning not only ensures the accuracy of the pattern, but also reduces the loss of dyes during washing, thereby enhancing color fastness.

[0041] The magnetic field can change the dynamics and arrangement of the fixing agent molecules, so that they form a more uniform and compact covering layer on the fiber surface, enhance the fixation effect of the dye, and form a protective film to reduce color loss.

[0042] It not only acts as a dye carrier to precisely control the distribution of dyes, but also improves color fastness and production efficiency through the effect of magnetic field during the color fixation process, thus improving the quality of printed mosquito nets and making them more competitive in the market.

[0043] The mosquito net material after dyeing and printing in S3 and S4 is washed to remove excess dye and printing paste.

[0044] Among them, after the dyeing and printing process of S3 and S4, the purpose of the washing step is to ensure the removal of excess dye and printing paste that are not fixed on the mosquito net base fabric. By removing the unfixed dye and printing paste, the washing ensures the clarity of the printed pattern and the vividness of the color. This can significantly improve the appearance quality of the finished product, avoid the dye from falling off or migrating during use, and maintain the lasting beauty of the product.

[0045] The appropriate water temperature and detergent should be selected according to the nature of the dye and print material being used. For most water-based dyes and print materials, the length of the wash cycle should be adjusted according to the thickness and density of the mosquito net material to ensure that all excess dye and print paste are effectively removed.

[0046] The post-processing step of S5 further includes drying the dyed and printed mosquito net material at a temperature not exceeding 60°C, and using magnetic separation technology to recover magnetic particles not fixed to the base fabric during the drying process to reduce material loss and improve resource utilization efficiency.

[0047] Among them, low-temperature drying technology effectively prevents fiber damage or color changes that may be caused by high temperatures by drying the dyed and printed mosquito net materials at a lower temperature, which helps to maintain the structural integrity of the textiles and the vividness of the colors.

[0048] Low-temperature drying reduces fiber weakening or deformation caused by high temperatures, extends the service life of textiles, prevents dye decomposition or discoloration at high temperatures, and ensures that the colors of printed patterns are bright and long-lasting.

[0049] Magnetic separation technology is used to recover magnetic particles that are not fixed to the base fabric during the drying process. By setting up a magnetic field, the dye residue containing magnetic particles is attracted and separated, and these particles can be reused.

[0050] The recovered magnetic particles and dyes can be reused in subsequent production batches, reducing raw material consumption and production costs.

[0051] In S5, the magnetic particles in the mosquito net are demagnetized to ensure that the dyed and printed mosquito net will not be affected by the magnetic field during use, maintaining its safety and comfort.

[0052] In S5, the magnetic particles in the mosquito net are demagnetized by using an alternating magnetic field.

[0053] Among them, the main purpose of demagnetization is to remove or reduce the residual magnetism of magnetic particles in the mosquito net to ensure that the mosquito net will not interfere with electronic equipment during use, nor will it absorb any metal particles, thereby maintaining safety and comfort of use.

[0054] Alternating magnetic field demagnetization applies a magnetic field with rapidly changing direction to magnetic particles, causing the magnetic domains inside the particles to be randomly arranged, thereby eliminating or significantly reducing the macroscopic magnetism.

[0055] The mosquito nets it produces have excellent mosquito-proof performance while being beautiful and comfortable, and by using environmentally friendly materials and processes, they meet sustainable development and environmental protection standards.

[0056] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
