Description

Technical Field

[0001] This invention relates to the field of functional finishing technology for textiles, and in particular to a finishing method for functional textiles based on atomized implantation. Background Technology

[0002] This invention relates to the field of functional finishing technology for textiles. With the increasing demand from consumers for added functionalities in textiles, such as antibacterial, aromatic, moisturizing, and anti-allergenic properties, functional finishing has become an important direction in textile finishing. Traditional processes typically employ methods such as impregnation, padding, or dyeing to apply functional auxiliaries to the fabric via an aqueous solution system, followed by high-temperature drying or baking to achieve fixation. This method is widely used in large-scale continuous production.

[0003] However, existing technologies have significant limitations: on the one hand, they rely on large amounts of water and auxiliaries, resulting in low raw material utilization and causing resource waste and environmental pollution; on the other hand, the processing is difficult to control precisely, making it impossible to achieve localized or patterned functional implantation, and they are particularly unsuitable for the post-processing of pre-cut or finished textile products such as garments. Furthermore, in small-batch customization or sample production scenarios, traditional processes involve large investments in equipment, complex procedures, and slow response times, making it difficult to meet the demands of flexible production.

[0004] Therefore, there is an urgent need for a new type of functional finishing technology that can reduce liquid consumption and improve material utilization while supporting flexible, precise and efficient functional treatment of finished fabrics, thereby breaking through the bottlenecks of traditional dyeing and finishing processes in terms of application scenarios, environmental performance and processing precision.

[0005] The purpose of this invention is to solve the problems of high consumption of liquid auxiliaries, inability to be applied locally, unsuitability for finished fabrics, and difficulty in meeting the needs of small-batch flexible production in traditional textile functional finishing processes. Summary of the Invention

[0006] The purpose of this invention is to solve the problems of existing methods for riveting busbar trunking, which rely on manual labor, resulting in high labor intensity, low efficiency, and inconsistent quality. This invention adopts the following technical solution: A finishing method for functional textiles based on atomized implantation includes the following steps: Step 1: Prepare a water-based treatment solution by mixing the functional ingredients with water in a preset ratio; Step 2: Inject the water-based treatment liquid into the physical pressurization atomization device and adjust the atomization pressure to ≤10 catties / square inch to form a fine mist with uniform particle size and no visible water droplets. Step 3: Spray the fine mist onto the target area of ​​the textile to form a uniform coverage without droplet residue, achieving localized or patterned functional finishing. Step 4: Allow to air dry in an environment without additional heating, or perform a low-temperature fixation treatment at ≤180℃ for no more than 3 minutes to ensure that the functional components are firmly attached to the fibers, thus completing the functional finishing process.

[0007] As described above, in a functional textile finishing method based on atomized implantation, the water-based treatment liquid is composed of the following components by mass percentage: 1%–20% functional ingredients, with the remainder being water.

[0008] As described above, in a functional textile finishing method based on atomization implantation, the physical pressurized atomization device is a manual press-type sprayer, a pneumatic spray bottle, or a pneumatic atomizing nozzle.

[0009] The above-described finishing method for functional textiles based on atomization implantation, wherein the atomization pressure is 2–10 catties / square inch, and the droplet size of the resulting fine mist is 1–50 micrometers.

[0010] As described above, a functional textile finishing method based on atomized implantation is used, wherein the target area is a specific part of the finished garment, a partial area of ​​the cut piece, or a pre-designed pattern area. Selective functional finishing is achieved by masking untreated areas or by using a template to guide the spraying.

[0011] As described above, in a functional textile finishing method based on atomized implantation, the low-temperature fixation treatment is performed at a temperature of 120°C to 180°C for a duration of 30 seconds to 3 minutes.

[0012] As described above, in a finishing method for functional textiles based on atomized implantation, when the functional component is a heat-sensitive substance, natural drying is performed under environmental conditions without additional heating.

[0013] The functional textile finishing method based on atomized implantation, as described above, wherein the functional ingredient is selected from at least one of antibacterial agents, fragrances, humectants, and anti-allergens, and its mass percentage in the water-based treatment solution is 0.1%–20%.

[0014] As described above, in a finishing method for functional textiles based on atomized implantation, when the functional component is a silver ion antibacterial agent, it is added in the form of a water-soluble silver salt, and its mass percentage in the water-based treatment solution is 0.5%–5%.

[0015] As described above, in a functional textile finishing method based on atomized implantation, when the textile is naturally dried in an environment without additional heating, the treated textile is placed in a ventilated environment and left to stand for 10–60 minutes, avoiding direct sunlight.

[0016] Implementing the embodiments of the present invention has the following beneficial effects: In this invention, a water-based functional treatment liquid is precisely applied to the target area of ​​textiles in the form of fine mist through physical pressurization atomization, significantly reducing the amount of liquid auxiliaries used and avoiding water waste and environmental pollution. Simultaneously, this method eliminates the need for dyeing vats or padding equipment, allowing for localized or zoned functional finishing of finished garments or cut pieces without disassembly or pre-wetting, effectively solving the technical bottleneck of traditional processes that cannot achieve small-batch, customized, and flexible production. Furthermore, by controlling atomization parameters and drying / fixing conditions, functional components can adhere evenly to the fiber surface and maintain good durability, taking into account environmental friendliness, applicability, and practicality.

Obviously, the accompanying drawings described below are only some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0018] Figure 1 This is a flowchart of a functional textile finishing method based on atomized implantation according to the present invention. Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figure 1 As shown, this invention proposes a finishing method for functional textiles based on atomized implantation, comprising the following steps: Step 1: Prepare a water-based treatment solution by mixing the functional ingredients with water in a preset ratio; the water-based treatment solution consists of the following components by mass percentage: 1%–20% functional ingredients, with the remainder being water; the water is deionized water, distilled water, or purified water; The functional ingredient is selected from at least one of antibacterial agents, fragrances, moisturizers, and anti-allergens, and its mass percentage in the water-based treatment solution is 0.1%–20%. When the functional ingredient is a silver ion antibacterial agent, it is added in the form of water-soluble silver salt, and its mass percentage in the water-based treatment solution is 0.5%–5%. When the functional ingredient is a fragrance, its mass percentage is preferably 5% to 20%. When the functional ingredient is a hyaluronic acid or hyaluronic acid-based moisturizer, its mass percentage is preferably 0.1% to 3%. During preparation, the functional ingredient is slowly added to water at room temperature while stirring at a speed of 300–600 rpm for 10–20 minutes until a uniform and stable clear solution or microemulsion dispersion is formed, thus obtaining the water-based treatment solution. Step 2: Inject the water-based treatment liquid into the physical pressurization atomization device and adjust the atomization pressure to ≤10 catties / square inch to form a fine mist with uniform particle size and no visible water droplets. The physical pressurization atomization device is a mechanical atomization device that does not rely on ultrasonic waves, heating, or electrostatic action, specifically selected from a manual press-type sprayer, a pneumatic spray bottle, or a low-pressure pneumatic atomizing nozzle. Adjust the working pressure of the device to 2 to 10 catties / square inch (approximately 0.14–0.70 MPa) so that the treatment liquid is broken into a fine mist with uniform particle size, no visible water droplets, and no droplet splashing when passing through the nozzle. The droplet size distribution of the fine mist is 1–50 micrometers, preferably 5–30 micrometers, to ensure that the mist can fully wet and penetrate when it comes into contact with textile fibers, while avoiding runoff, stains, or excessive local deposition due to excessively large droplets. Step 3: Spray the fine mist onto the target area of ​​the textile, controlling the spraying distance to be 10–30 cm and the nozzle moving speed to be 5–20 cm / s, to form a uniform coverage without droplet residue, achieving localized or patterned functional finishing; the target area is a specific part of the finished garment, a partial area of ​​the cut piece, or a pre-designed pattern area, and selective functional finishing is achieved by masking non-treated areas or using a template to guide the spraying; Step 4: Dry or fix the atomized textiles, specifically in the following two ways: Natural drying: When the functional component is a heat-sensitive substance (such as plant fragrance, hyaluronic acid, vitamin derivatives or enzyme active ingredients), place the textile in a ventilated environment and let it stand for 10–60 minutes without applying an additional heat source. The ambient temperature should be controlled at 10–30°C, and direct sunlight should be avoided to allow the treatment solution to evaporate naturally and the functional component to adhere to the fiber surface. Low-temperature fixation treatment: When the functional component is a non-heat-sensitive substance (such as silver ion antibacterial agent), the textile is placed in a hot air oven, ironing equipment or continuous setting machine at 120°C to 180°C for 30 seconds to 3 minutes to fix the functional component firmly onto the fiber through heat. The temperature of the low-temperature fixation treatment shall not exceed 180°C and the treatment time shall not exceed 3 minutes, so as to balance functional fastness and protection against heat damage to the fabric. Example

[0021] The atomized implantation method for silver ion antibacterial function in finished garments involves using a commercially available manual press-type sprayer (working pressure approximately 2.5 catties / square inch) to prepare a water-based treatment solution: slowly add 5 g of silver nitrate (as a water-soluble silver ion antibacterial agent) to 95 g of deionized water, and stir at 400 rpm for 15 minutes at room temperature to obtain a clear and transparent water-based treatment solution (silver ion content of 5 wt%).

[0022] Inject the above treatment solution into the sprayer. Select a pre-sewn pure cotton T-shirt as the textile to be treated and lay it flat on a ventilated work surface. Cover the T-shirt with moisture-resistant masking tape, except for the underarm area, exposing only a 10 cm × 10 cm area under each armpit as the target treatment area.

[0023] The operator holds the sprayer, keeping the nozzle about 15 cm away from the fabric surface, and moves it back and forth at a constant speed (about 10 cm / s) to evenly spray the fine mist onto the exposed area until the fabric surface is slightly damp but without visible water droplets (the droplet size is measured to be 8–35 μm by a laser particle size analyzer).

[0024] After spraying, place the T-shirt in a well-ventilated environment at 25℃ and 60% relative humidity for 30 minutes to air dry. Then, place it in a hot air oven and treat it at 160℃ for 2 minutes to complete the low-temperature fixation.

[0025] Testing revealed that the initial antibacterial rate (Staphylococcus aureus) in the armpit area of ​​the treated T-shirt reached 99.5%. After 20 washes according to GB / T8629-2017 standard, the antibacterial rate remained at 83%, meeting the AAA-grade antibacterial textile standard. The fabric was soft to the touch, without yellowing or stiffness, and no functional components migrated from the untreated areas. Example

[0026] A method for atomizing and embedding ginseng fragrance into a functional scarf involves preparing a water-based treatment solution: 20 g of natural ginseng plant fragrance (containing volatile terpenes and alcohols, which are heat-sensitive substances) and 1 g of nonionic emulsifier (as an auxiliary dispersant to ensure stable dispersion of the fragrance in water) are added to 79 g of deionized water. The mixture is stirred at 500 rpm for 20 minutes at room temperature to obtain a microemulsion-like, clear, and transparent water-based treatment solution (fragrance content of 20 wt%).

[0027] A commercially available air-pressure garden sprayer (inflated to approximately 3 catties / square inch) was used as the physical pressurization atomization device to inject the above-mentioned treatment liquid. A pre-sewn silk scarf was selected as the textile to be treated and laid flat on the work surface. A perforated pattern template (patterned as "auspicious clouds," 8 cm × 8 cm) was used and placed tightly against one end of the scarf, exposing only the opening area of ​​the template as the target treatment area.

[0028] The operator holds the spray bottle, keeping the nozzle about 20 cm away from the surface of the scarf, and moves it slowly and evenly to spray the fine mist evenly onto the opening area of ​​the template until the fabric has a slightly soft and lustrous sheen but no droplets accumulate (it was observed that the droplets were fine, without any dripping or stains).

[0029] After spraying, the template was removed immediately, and the scarf was placed in a well-ventilated and dark indoor environment at 22°C and left to dry naturally for 45 minutes. No external heat source was applied throughout the process.

[0030] Sensory evaluation and GC-MS testing showed that the treated areas had a distinct and gentle ginseng aroma. After 20 washes according to AATCC 135 standards (40℃, neutral detergent, machine wash for 30 minutes), a faint fragrance remained. The scarf felt smooth to the touch, with no yellowing, hardening, or fiber damage. No fragrance diffused in the untreated areas, and the pattern boundaries were clear. Example

[0031] The hyaluronic acid moisturizing function is incorporated into the atomized implantation method of the baby bodysuit. A water-based treatment solution is prepared by slowly adding 0.5 g of medical-grade sodium hyaluronate (molecular weight approximately 800,000 Daltons, used as a moisturizer) to 99.5 g of deionized water. The solution is stirred at 300 rpm for 25 minutes at room temperature until completely dissolved, yielding a clear, low-viscosity water-based treatment solution (hyaluronic acid content 0.5 wt%). This formula contains no preservatives, fragrances, penetration enhancers, or fixatives, ensuring safety for infants' skin.

[0032] A low-pressure pneumatic atomizing nozzle (working pressure approximately 2 catties / square inch, droplet size measured to be 5–25 μm) was selected as the physical pressurization atomization device and connected to a small air compressor. A pre-sewn pure cotton baby bodysuit was selected as the textile to be treated and laid flat on a clean work surface. A moisture-resistant masking film was used to cover the area except for the chest area (10 cm × 15 cm), leaving only this area exposed as the target treatment area. This area is close to the baby's neck and chest, is prone to drying, and requires enhanced moisturizing care.

[0033] Turn on the atomizing device, keep the nozzle about 12 cm away from the fabric surface, and spray at a uniform speed of 8 cm / s to make the fine mist evenly cover the target area. The fabric surface will have a slightly damp sheen, without water droplets, drips, or stains.

[0034] After spraying, place the bodysuit in a well-ventilated, dark indoor environment at 20°C and 50% relative humidity, and let it air dry for 60 minutes. No heating treatment was performed throughout the process to avoid thermal degradation of the hyaluronic acid.

[0035] According to tests conducted by a third-party testing agency, a uniform layer of hyaluronic acid adhered to the fiber surface of the treated area. Even after simulating daily wear friction of infants and young children and washing 10 times according to GB / T 8629 standard, significant residual moisturizing factors were still detected. Skin irritation tests (human patch test, n=30) showed that the treated fabric was neither sensitizing nor irritating to infants' skin. Untreated areas maintained their original properties and showed no cross-contamination. Example

[0036] A method for atomizing and embedding antibacterial and anti-allergic functions into adult loungewear with zoned, multi-functional design. Two types of water-based treatment solutions were prepared: Treatment solution A (antibacterial type): Add 3 g of silver nitrate (water-soluble silver ion antibacterial agent) to 97 g of deionized water and stir at 400 rpm for 15 minutes at room temperature to obtain a clear solution (silver ion content 3 wt%). Treatment solution B (anti-allergy type): Add 2 g of dipotassium glycyrrhizate (a commonly used anti-allergy active ingredient, heat-sensitive) to 98 g of deionized water, stir at 500 rpm for 20 minutes at room temperature to obtain a transparent solution (anti-allergy agent content 2 wt%).

[0037] Neither treatment solution contained any penetrant, leveling agent, or fixing agent.

[0038] Two independent manual press-type sprayers (working pressure approximately 2.8 catties / square inch) were selected, and each was filled with treatment solution A and treatment solution B, respectively. A pre-sewn, pure cotton adult loungewear garment was chosen as the object to be treated and laid flat and secured.

[0039] Divide the target areas according to functional requirements: Underarm and collar areas (prone to bacterial growth) → Use treatment solution A for antibacterial treatment; Cuffs and hem (areas in contact with skin that are prone to contact with sensitive skin) → Use treatment solution B for anti-allergy treatment.

[0040] The masking method is used in a step-by-step manner: First, cover the cuffs and hem with a moisture-resistant masking film, leaving only the armpits and collar exposed. Then, use a sprayer containing treatment solution A to spray the solution at a uniform speed from a distance of 15 cm from the fabric to form a uniform mist coverage. After the treatment solution A has dried naturally (about 5 minutes), remove the masking film and reapply the masking film to cover the treated armpit and collar areas. Then, use a sprayer containing treatment solution B to atomize and spray the cuffs and hem areas in the same way.

[0041] After spraying, place the housewear in a well-ventilated, dark environment at 23°C for 40 minutes to air dry naturally. No heating was used throughout the process to protect the activity of the anti-allergic ingredients.

[0042] Test results: The initial antibacterial rate (E. coli) in the armpit area reached 99.2%, and remained above 85% after 15 washes; Human patch tests (n=25) showed a significant reduction in skin irritation in the cuff area, with stable anti-allergic effects; The two functional areas have clear boundaries and no cross-contamination; the fabric has a soft feel overall, without stiffness or discoloration. The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.
