Description

Technical Field

[0001] This invention relates to the field of fabric treatment technology, and more specifically to a fabric treatment emulsion and a fabric composite material. Background Technology

[0002] Wear resistance and durability are key performance requirements for protective equipment, especially in industries such as waste recycling, police duty, metal processing, and die-cutting. Workers often face the risk of puncture from extremely sharp objects such as injection needles. Once gloves or protective clothing are punctured during work, it is often difficult to detect immediately, which can not only cause trauma but also lead to the risk of infection such as tetanus, hepatitis B, or HIV, resulting in serious psychological burden and economic losses for the injured.

[0003] Currently, there is a lack of ideal materials in existing technologies that can simultaneously achieve high puncture resistance, high abrasion resistance, good flexibility, and breathability. For example, Superfabric achieves puncture resistance and abrasion resistance by attaching hard compound blocks to the fabric surface; however, the significant increase in material rigidity often requires multiple layers, severely impacting wearing flexibility and comfort. Another type, aramid woven fabric, typically Turtleskin, while possessing good needle-punch resistance, suffers from relatively insufficient abrasion resistance, a stiff feel, and poor flexibility, similarly limiting its application in scenarios requiring prolonged, high-activity work. Furthermore, most existing high-protection composites, such as multi-layered fine metal mesh and resin-impregnated fabric sheets, generally suffer from poor flexibility and a stiff feel.

[0004] Research indicates that one of the main mechanisms by which sharp objects puncture fabrics is the "window effect," where yarns slip at the moment of puncture, creating localized gaps that allow for penetration. The key to suppressing this effect lies in increasing the frictional resistance of the fiber surface, thus limiting yarn slippage. However, existing surface treatment technologies often struggle to create a uniform, robust coating on the fiber surface that doesn't affect the fabric's original feel. This results in treated fabrics either offering limited improvement in protective performance or losing their intended flexibility and comfort.

[0005] Furthermore, traditional shear-thickening fluids (STFs) face significant technical bottlenecks in practical applications. Due to their inherent high viscosity, STFs cannot directly and uniformly wet porous substrates, necessitating the introduction of small-molecule, volatile solvents for dilution. However, dilution leads to a substantial decrease in system viscosity, resulting in a loss of suspension stability of the dispersed phase particles and subsequent rapid sedimentation. Without continuous, vigorous internal circulation and stirring, particles rapidly aggregate in the lower layer of the system, forming a hard, dense deposition layer. This also reduces the effective concentration of the diluent, causing significant inconvenience for large-scale production and field applications. Summary of the Invention

[0006] The first objective of this invention is to provide a fabric treatment emulsion that imparts excellent abrasion and puncture resistance to ordinary fabrics while maintaining their flexibility and wearing comfort. The second objective of this invention is to provide a fabric composite material that significantly improves the abrasion resistance and sharp object puncture resistance of fabrics without substantially altering their original softness and breathability.

[0007] The technical solution adopted for the first objective of this invention is as follows:

[0008] A fabric treatment emulsion is a homogeneous treatment emulsion formed by shear emulsification of an oily fluid and an aqueous solvent. The oily fluid is a fluid in which component one is uniformly dispersed in component two. The aqueous solvent is a mixture of components three and four. Component one is a hard inorganic nanoparticle with a hydrophobic modified surface, which is a mixture of one or more of nano-silica spherical particles and deposited calcium carbonate particles. Component two is a mixed oily solvent composed of paraffin oil and methyl silicone oil. Component three is a hydrophilic and lipophilic surfactant. Component four is purified water or deionized water.

[0009] The hydrophobically modified spherical silica nanoparticles and hydrophobically modified deposited calcium carbonate particles of this invention are hard inorganic nanoparticles with a certain degree of monodispersity. This invention uses a mixed oily solvent of paraffin oil and methyl silicone oil for the following reasons: First, both are non-polar solvents, which are compatible with the hydrophobically modified spherical silica particles and hydrophobically modified deposited calcium carbonate particles, avoiding particle agglomeration or system stratification due to polarity differences; second, both have excellent chemical stability and are not prone to reacting with other components in the system, ensuring the long-term stability of the solvent system and the final product; third, both have suitable viscosity adjustment ranges, and the mixing ratio can be optimized to meet the dispersion requirements of inorganic particles; furthermore, both are widely available and cost-controllable, while other oily solvents, such as polyether-modified silicone oil, may have polarity mismatches or insufficient stability.

[0010] The treatment emulsion of the present invention can construct a uniform and firm impedance coating on the surface of fabric fibers and inside the fabric structure. By increasing the micro-roughness of the fiber surface, the friction coefficient between fibers is increased, effectively suppressing the "window effect" of sharp objects piercing the fabric, while maintaining the original soft hand feel, bending flexibility and breathability of the fabric to the greatest extent.

[0011] The present invention also has the following preferred designs:

[0012] The nanoparticles in component one of this invention have a particle size range of 120 nm to 13000 nm. When a treated emulsion with nanoparticles of 120 nm to 13000 nm is used to impregnate a substrate, it can form a dense and uniform functional layer on the substrate surface, fully utilizing its abrasion and puncture resistance properties. When the particle size is less than 120 nm, the particles are prone to adsorption and aggregation due to van der Waals forces, leading to agglomeration and disrupting dispersion stability. Furthermore, treated emulsions with excessively small particle sizes can cause excessive particle penetration into the substrate when impregnating fabrics, and the cost of nanoparticle preparation increases significantly with decreasing particle size. When the particle size is greater than 13000 nm, the sedimentation rate will significantly increase, leading to multiple risks: during storage or processing, large-diameter particles are prone to rapid sedimentation and stratification, disrupting the system's uniformity; during the coating or adsorption stage of the treated emulsion onto the substrate, excessively rapid sedimentation can cause uneven particle distribution on the substrate surface, severely reducing the film uniformity of the treated emulsion.

[0013] In component two of this invention, the mass fraction ratio of paraffin oil to methyl silicone oil ranges from 3:7 to 5:5. Within this ratio, the two exhibit excellent compatibility, forming a homogeneous and stable mixture. Simultaneously, the surface tension and viscosity of the mixed oily solvent are well-matched, effectively wetting the surface of the nanoparticles and reducing interparticle aggregation forces, thereby achieving uniform and stable dispersion of the nanoparticles. Within this ratio range, the nanoparticles can be uniformly and stably dispersed in the mixed oily solvent. If the ratio exceeds this range, the compatibility between the nanoparticles and the mixed oily solvent decreases, the mixture loses its fluidity, and forms a paste.

[0014] The viscosity of the methyl silicone oil in this invention is 20–350 cSt. If the viscosity of the methyl silicone oil is too high, the mixed system will generate strong internal frictional resistance, and a large amount of shear energy will be absorbed and dissipated during the dispersion process. This results in insufficient effective shear force transferred to the nanoparticle aggregates, making it difficult for the particle aggregates to be fully opened, and the particle surface cannot achieve efficient wetting, easily leaving micro-aggregates. At the same time, the high viscosity environment will strongly inhibit the Brownian motion of the particles, significantly reducing the migration ability of the particles, making it difficult for the nanoparticles to fully integrate into the solvent system, thus adversely affecting the dispersion effect and storage stability of the system.

[0015] The surfactant in component three of this invention has an HLB value of 8–18. The HLB value is a numerical value representing the balance between hydrophilic and lipophilic groups in a surfactant molecule. Generally, an HLB value of 3–6 indicates a stronger hydrophilic-lipophilic property and greater oil solubility; common types include glyceryl monostearate, Span series (such as Span 80), calcium / magnesium salts of higher fatty acids, and fatty alcohols. An HLB value of 8–18 indicates a more balanced hydrophilic-lipophilic property; common types include the Tween series, poloxamer 184 (trade name: Pluronic® L-64), Triton X-100 (trade name: Triton™ X-100), and polyoxyethylene lauryl ether (trade name: Brij® L4). When the HLB value is 19–40, it belongs to the super-hydrophilic emulsifier category, soluble only in the aqueous phase and almost insoluble in the oil phase. Common types include sodium dodecyl sulfate (SDS) and poloxamer 407 (trade name: Pluronic® F-127). At room temperature, when the HLB value is 8–18, it is particularly suitable for emulsifying and dispersing oily substances in water-based systems.

[0016] In the emulsion treated in this invention, the mass fraction of the core components is limited as follows: component one is 10%–25%, component two is 5%–20%, and the remaining portion consists of components three and four. If the total mass fraction of components one and two is less than 15%, the fabric treated with this emulsion will not achieve the expected abrasion and puncture resistance. If the total mass fraction of the two components is greater than 45%, it will be difficult to prepare a stable emulsion system, which will easily lead to nanoparticle aggregation and rapid coalescence of oil phase droplets, ultimately causing emulsion stratification, demulsification, or a sharp decline in stability, failing to meet the basic conditions for subsequent performance testing.

[0017] The mass fraction of component three in the aqueous solvent of the present invention is greater than or equal to 0.2 wt%.

[0018] The modification method of the nanoparticles of the present invention can be as follows: prepare a weakly acidic aqueous solution with a pH value of 4-6; add dodecyltriethoxysilane to the weakly acidic aqueous solution under continuous stirring to hydrolyze it and form a surface modification treatment solution; disperse the unmodified nanoparticles in another part of water; and slowly add the surface modification treatment solution dropwise under the condition of ensuring sufficient stirring to obtain a mixture; control the temperature of the reaction system to be maintained at about 65 degrees Celsius; and continue stirring the reaction for 3-4 hours to ensure that the surface of the nanoparticles is fully grafted with hydrophobic groups; after the reaction is completed, filter the mixture, collect the solid, and after washing and drying, obtain the surface hydrophobically modified nanoparticle dry powder.

[0019] The nanoparticle powder can be added in batches to the pre-prepared component two. Through mechanical stirring or homogenization, the nanoparticles are fully dispersed to obtain a stable oily fluid that is uniform, free of sediment and visible agglomerates. If aggregates still exist after dispersion, further grinding or high-speed shearing is required until the system is completely uniform and has good fluidity, thus obtaining the oily fluid.

[0020] The technical solution adopted for the second objective of this invention is as follows:

[0021] A fabric composite material is obtained by adhering an oily fluid of the fabric treatment emulsion to the fabric surface and the interior of the fabric structure.

[0022] The fabric treatment emulsion of the present invention can be applied to the fabric by means of impregnation, spraying, coating, etc.

[0023] In the fabric composite material of the present invention, the mass fraction of oily fluid is 20% to 40%.

[0024] The fabric of the present invention adopts a double rib knit structure or a double rib knit variant knit structure.

[0025] The yarn of the fabric described in this invention is ultra-high molecular weight polyethylene fiber or composite yarn containing ultra-high molecular weight polyethylene fiber.

[0026] The ultra-high molecular weight polyethylene fiber of the present invention has a fineness of 150D to 400D.

[0027] The present invention has the following beneficial effects:

[0028] 1. The treatment emulsion of the present invention can form a firm and uniform nanocomposite coating on the surface of fabric fibers. While significantly improving the fabric's resistance to needle puncture and abrasion, it retains the fabric's original soft hand feel, bending flexibility and breathability to the greatest extent. It overcomes the stiffness, stuffiness and other discomfort caused by traditional hard protective materials or thick coatings, and achieves a unity of protective performance and wearing comfort.

[0029] 2. The water-based emulsion of the present invention has excellent stability and can maintain a uniform dispersion state for more than several weeks at room temperature. If slight stratification occurs after long-term standing, it can be restored to a uniform state by conventional stirring or brief vortex oscillation, without the need for a complicated high-shear redispersion process.

[0030] 3. The fabric composite material of the present invention has a simple preparation process and wide applicability. When applied, only conventional processing technology is required to complete the fabric finishing. No complex equipment is needed, which makes it easy to connect with the existing textile processing flow and subsequent processing. Moreover, the main components of the treatment emulsion are all commercially available common chemical raw materials. The preparation process is simple and the conditions are mild. No special or expensive equipment is required. The raw material cost is controllable, the economic benefits are high, and it is conducive to large-scale production and promotion.

[0034] To make the objectives, technical solutions, and advantages of the present invention more apparent, exemplary embodiments according to the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are merely a part of the embodiments of the present invention, and not all of the embodiments of the present invention. It should be understood that the present invention is not limited to the exemplary embodiments described herein. Based on the embodiments of the present invention described herein, all other embodiments obtained by those skilled in the art without inventive effort should fall within the protection scope of the present invention.

[0035] It should be understood that the invention can be embodied in various forms and should not be construed as being limited to the embodiments set forth herein. Rather, providing these embodiments will make the disclosure thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0036] Example 1:

[0037] A fabric treatment emulsion, comprising the following components:

[0038] Component 1: Hard inorganic nanoparticles with hydrophobic surface modification, using deposited calcium carbonate particles. The deposited calcium carbonate particles are prismatic with an average particle size of 850 nm. The particle size here refers to the equivalent sphere diameter, which is directly measured by the Dynamic light scattering (DLS) method.

[0039] Component 2: A mixed oily solvent composed of paraffin oil and methyl silicone oil, with a mass fraction ratio of 5:5;

[0040] Component 3: A hydrophilic and lipophilic surfactant, Pluronic® L-64, with an HLB value of 12–18;

[0041] Component 4: Deionized water;

[0042] The treated emulsion is prepared using the following method:

[0043] First, 35g of anhydrous ethanol, 3.5g of dodecyltriethoxysilane, and 1.9g of deionized water were mechanically mixed in a container to form a homogeneous solution. The solution was adjusted to acidity and stirred in a constant temperature environment of 45℃ for 20 minutes to obtain the surface modification treatment solution.

[0044] 700g of deposited calcium carbonate particles were added to 7000mL of deionized water and stirred at 60℃ for 5 minutes to obtain a suspension. Then, the surface-modified treatment solution was slowly added dropwise to the suspension at a rate of 3mL / min. After the addition was complete, the mixture was stirred at 60℃ for another 5 minutes, and then the temperature was raised to 65℃ for 3 hours. After the reaction was complete, the mixture was filtered, and the solid was collected. The obtained solid was dried in an 80℃ oven to obtain surface-hydrophobic modified calcium carbonate particle powder, which is component one.

[0045] 75g of paraffin oil and 75g of methyl silicone oil were mixed to obtain component two, with a mass ratio of 5:5. The methyl silicone oil had a viscosity of 20 cSt. The mixture was thoroughly stirred to obtain a homogeneous oily solvent mixture. Under high-speed dispersion stirring, 383.3g of modified calcium carbonate particle powder was slowly added to the oily solvent mixture at a rate of 2g / min. Strong stirring was maintained throughout the addition process to ensure uniform particle dispersion. If dispersion became difficult due to excessively high system viscosity, appropriate heating could be used to reduce the viscosity, ultimately yielding a homogeneous, flowable oily fluid.

[0046] 10g of Pluronic® L-64 was dissolved in 990g of deionized water and stirred until completely dissolved to obtain an aqueous solvent with a Pluronic® L-64 mass fraction of 1wt%. The previously prepared oily fluid was slowly added to the aqueous solvent under high-speed shearing at 3500rpm, and the mixture was continuously sheared and dispersed for 5 minutes to initially emulsify the system. Subsequently, the mixture was further processed using an ultrasonic disperser until a uniform, fine, and stable milky white treated emulsion was formed. The modified calcium carbonate particles (component one) accounted for 25% of the treated emulsion by the formula: (mass of component one / (mass of component one + mass of component two + mass of component three + mass of component four)) × 100%. The mixed oily solvent (component two) accounted for 10% of the treated emulsion by the formula: (mass of component two / (mass of component one + mass of component two + mass of component three + mass of component four)) × 100%.

[0047] A double-ribbed fabric woven from 400D ultra-high molecular weight polyethylene fiber was immersed in the treatment emulsion of this embodiment for 30 seconds. Excess treatment emulsion was then squeezed out using rollers, and the fabric was thoroughly dried in an oven to obtain a soft, breathable, needle-resistant, and abrasion-resistant composite material. The untreated fabric had a basis weight of 486.7 g / m². 2 The basis weight of the fabric composite material is 811.2 g / m². 2 The mass fraction of oily fluid in the double-ribbed fabric composite material woven from 400D ultra-high molecular weight polyethylene fiber is 40%, calculated as: (fabric composite weight - untreated fabric weight) / fabric composite weight × 100%.

[0048] A double-ribbed fabric woven from 300D ultra-high molecular weight polyethylene fiber is immersed in the treatment emulsion of this embodiment for 30 seconds, then excess treatment emulsion is squeezed out through rollers, and after being fully dried in an oven, a soft and breathable needle-punch-resistant and abrasion-resistant fabric composite material is obtained. Figure 1 As shown in the scanning electron microscope images, before emulsion treatment, there are obvious gaps and voids between the fiber bundles of the double rib fabric woven from 300D ultra-high molecular weight polyethylene fibers; Figure 2 As shown in the scanning electron microscope images, after emulsion treatment, the oily fluid fully adheres to and fills the fabric surface and fiber gaps, significantly closing the original gaps and making the fabric surface smoother and more continuous. The untreated fabric had a basis weight of 460 g / m². 2 The basis weight of the fabric composite material is 686.6 g / m². 2 The mass fraction of oily fluid in the double-ribbed fabric composite material woven from 300D ultra-high molecular weight polyethylene fiber is 33%.

[0049] A double-ribbed fabric woven from 200D ultra-high molecular weight polyethylene fiber was immersed in the treatment emulsion of this embodiment for 30 seconds. Excess treatment emulsion was then squeezed out through rollers, and the fabric was thoroughly dried in an oven to obtain a soft, breathable, needle-punch-resistant, and abrasion-resistant composite material. The untreated fabric had a basis weight of 297 g / m². 2 The basis weight of the fabric composite material is 420.7 g / m². 2 The mass fraction of oily fluid in the double-ribbed fabric composite material woven from 200D ultra-high molecular weight polyethylene fiber is 29.4%.

[0050] A double-ribbed fabric woven from 150D ultra-high molecular weight polyethylene fiber was immersed in the treatment emulsion of this embodiment for 30 seconds. Excess treatment emulsion was then squeezed out using rollers, and the fabric was thoroughly dried in an oven to obtain a soft, breathable, needle-resistant, and abrasion-resistant composite material. The untreated fabric had a basis weight of 220 g / m². 2 The basis weight of the fabric composite material is 285.7 g / m². 2The mass fraction of oily fluid in the double-ribbed fabric composite material woven from 150D ultra-high molecular weight polyethylene fiber is 23%.

[0051] The four fabric composite materials mentioned above were tested for needle puncture resistance, abrasion resistance, softness, and air permeability.

[0052] The needle puncture resistance test was conducted according to ASTM F2878-19 "Standard test method for protective clothing material resistance to hypodermic needle puncture". A 25G needle was used to completely puncture the composite fabric under test at a constant speed of 500 mm / min. The maximum resistance generated by the material during puncture was recorded as the material's needle puncture resistance. At least 36 sets of data were tested for each material, and the average of these 36 sets was used as the material's needle puncture resistance to minimize the influence of the local microstructure of the composite surface on the needle puncture force.

[0053] The abrasion resistance test was conducted according to the method described in Section 6.1, "Abrasion Resistance," of EN388 "Protective gloves against mechanical risks." The test material was cut to an appropriate size and placed on a Martindale abrasion tester. Under a pressure of 9 kPa, the material was repeatedly rubbed with 180 grit sandpaper until it broke, and the number of rubs at which breakage occurred was recorded. Two parallel samples were tested for each type of material, and the minimum value between the two sets of data was taken as the abrasion resistance of the material.

[0054] The softness test involves selecting a 15mm × 5mm fabric sample, fixing one end by 5mm, and allowing the other end (20mm) to hang naturally. The bending angle formed between the hanging sample and a horizontal surface is measured. A larger bending angle indicates better softness, while a smaller bending angle indicates poorer softness. This invention uses the average bending angle of the fabric as the basis for defining softness: an average bending angle <30° is rated as extremely stiff; an average bending angle between 30° and 60° is rated as moderately soft; and an average bending angle >60° is rated as soft.

[0055] The air permeability test was conducted according to GB / T5453-1997 "Textiles - Determination of Air Permeability of Fabrics". The composite material to be tested was stretched and fixed with the front side facing down, and the test area was set to 20 cm². 2 With a pressure drop of 100 Pa, the air permeability of the material is obtained by calculating the volume of air passing vertically through a unit area sample per unit time.

[0056] Table 1 shows the test data for needle puncture resistance, abrasion resistance, softness, and air permeability of the four fabric composite materials in this embodiment, as well as the test data for needle puncture resistance, abrasion resistance, softness, and air permeability of the four fabrics without impregnation treatment.

[0057] Table 1:

[0058]

[0059] The data comparison above shows that the fabrics impregnated with the emulsion treated in this embodiment exhibit significantly improved needle-punch resistance and abrasion resistance. This indicates that the emulsion used in this embodiment can be effectively applied in fabric impregnation processes, helping to substantially improve the fabric's needle-punch resistance and abrasion resistance. Furthermore, while improving performance, the fabrics maintain good softness and breathability.

[0060] In this embodiment, the treated emulsion was placed at different temperatures for 7 days, and the resulting fabric composite material was tested for its needle puncture resistance. The storage stability of the treated emulsion was also investigated, and the results are as follows:

[0061] After being stored at 0℃ for 7 days, the mixture was brought to room temperature (25℃±5℃) and ultrasonically vibrated for 5 minutes to mix it evenly. The double rib fabric woven from 300D ultra-high molecular weight polyethylene fiber was then immersed in the treated emulsion for 30 seconds. The excess treated emulsion was then squeezed out by rollers and placed in an oven to dry thoroughly to obtain the composite material. Its needle puncture resistance was measured to be 4.66N.

[0062] After being stored at room temperature (25℃±5℃) for 7 days, the mixture can be stirred for 5 minutes to achieve uniformity. The double rib fabric woven from 300D ultra-high molecular weight polyethylene fiber is immersed in this treatment emulsion for 30 seconds, and then the excess treatment emulsion is squeezed out through rollers. After being placed in an oven to dry fully, the composite material is obtained, and its needle puncture resistance is measured to be 4.71N.

[0063] After being stored at 70℃ for 7 days, the mixture was cooled to room temperature and then ultrasonically vibrated for 5 minutes to achieve uniform mixing. A double-ribbed fabric woven from 300D ultra-high molecular weight polyethylene fiber was then immersed in this treatment emulsion for 30 seconds. The excess treatment emulsion was then squeezed out through rollers and placed in an oven to dry thoroughly to obtain the composite material. Its needle puncture resistance was measured to be 4.63N.

[0064] Example 2:

[0065] The difference from Example 1 is that the average particle size of the deposited calcium carbonate particles in Component 1 of this example is 13000 nm, and Component 4 is pure water.

[0066] The treated emulsion is prepared using the following method:

[0067] 17.5 g of anhydrous ethanol, 1.75 g of dodecyltriethoxysilane, and 1 g of purified water were mechanically mixed in a container to form a homogeneous solution. The solution was adjusted to acidity and stirred at a constant temperature of 50°C for 30 minutes to obtain the surface modification treatment solution.

[0068] 350g of deposited calcium carbonate particles were added to 4650mL of purified water and stirred at 60℃ for 5 minutes to obtain a suspension. Then, the surface-modified treatment solution was slowly added dropwise to the suspension at a rate of 2mL / min. After the addition was complete, the mixture was stirred at 60℃ for another 5 minutes, and then the temperature was increased to 65℃ for 4 hours. After the reaction was complete, the mixture was filtered, and the solid was collected. The obtained solid was dried in an 80℃ oven to obtain hydrophobically modified calcium carbonate particle powder.

[0069] 29.5g of paraffin oil and 29.5g of methyl silicone oil were mixed in a mass ratio of 5:5, with the methyl silicone oil having a viscosity of 20 cSt. The mixture was thoroughly stirred to obtain a homogeneous oily solvent mixture. Under high-speed dispersing stirring, 117g of modified calcium carbonate powder was slowly added to the oily solvent mixture at a rate of 2g / min. Strong stirring was maintained throughout the addition process to ensure uniform particle dispersion. If dispersion became difficult due to excessively high system viscosity, appropriate heating could be used to reduce the viscosity, ultimately yielding a homogeneous, flowable oily fluid.

[0070] 2g of Pluronic® L-64 was dissolved in 998g of purified water and stirred until completely dissolved to obtain an aqueous solvent with a Pluronic® L-64 mass fraction of 0.2wt%. The previously prepared oily fluid was slowly added to the aqueous solvent under high-speed shearing at 3500rpm, and the mixture was continuously sheared and dispersed for 10 minutes to achieve initial emulsification. Subsequently, the mixture was further processed using an ultrasonic disperser until a uniform, fine, and stable milky white emulsion was formed. The modified calcium carbonate particles accounted for 10% of the mass fraction of the emulsion, and the mixed oily solvent accounted for 5% of the mass fraction.

[0071] A double-rib fabric woven from 300D ultra-high molecular weight polyethylene fiber was treated using a spray coating method. The treatment emulsion of this embodiment was evenly sprayed onto both sides of the fabric. After low-temperature pre-drying, it was sprayed again for additional treatment. The fabric was then lightly pressed flat by rollers and placed in an oven for thorough drying to obtain a soft, breathable, needle-punch-resistant, and abrasion-resistant composite material. The untreated fabric had a basis weight of 460 g / m². 2 The basis weight of the fabric composite material is 575 g / m². 2The mass fraction of the oily fluid in the double-ribbed fabric composite material woven from 300D ultra-high molecular weight polyethylene fiber is 20%. After the fabric composite material was prepared, it was tested, showing a needle-punch resistance of 4N and an abrasion resistance of 45,000 cycles. After being placed at different temperatures (0℃, 25℃±5℃, 70℃) for one week, the treated emulsion could be uniformly dispersed under mechanical stirring or ultrasonic dispersion, exhibiting good stability. The fabric treated with the emulsion of this embodiment showed a significant improvement in both needle-punch resistance and abrasion resistance, indicating that the treated emulsion of this embodiment can be well applied in fabric spraying processes to significantly improve the needle-punch resistance and abrasion resistance of fabrics.

[0072] Example 3:

[0073] The difference from Example 1 is that the nanoparticles in Component 1 of this example are spherical nano-silica particles with an average particle size of 120 nm. The particle size refers to the equivalent sphere diameter, which is directly measured by the DLS method.

[0074] The treated emulsion is prepared using the following method:

[0075] 17.5 g of anhydrous ethanol, 1.75 g of dodecyltriethoxysilane, and 1 g of deionized water were mechanically mixed in a container to form a homogeneous solution. The solution was adjusted to acidity and stirred at a constant temperature of 50°C for 30 minutes to obtain the surface modification treatment solution.

[0076] 350g of silica spherical particles were added to 3500mL of purified water and stirred at 60℃ for 5 minutes to obtain a suspension. Then, the surface-modified treatment solution was slowly added dropwise to the suspension at a rate of 2mL / min. After the addition was complete, the mixture was stirred at 60℃ for another 5 minutes, and then the temperature was raised to 65℃ for 3 hours. After the reaction was complete, the mixture was filtered, and the solid was collected. The obtained solid was dried in an 80℃ oven to obtain a dry powder of surface-hydrophobic modified silica spherical particles.

[0077] 154g of paraffin oil and 154g of methyl silicone oil were mixed in a mass ratio of 5:5, with the methyl silicone oil having a viscosity of 20 cSt. The mixture was thoroughly stirred to obtain a homogeneous oily solvent mixture. Under high-speed dispersing stirring, 231g of modified silica spherical dry powder was slowly added to the oily solvent mixture at a rate of 2g / min. Strong stirring was maintained throughout the addition process to ensure uniform particle dispersion. If dispersion became difficult due to excessively high system viscosity, appropriate heating could be used to reduce the viscosity. A homogeneous, flowable oily fluid was ultimately obtained.

[0078] 20g of Pluronic® L-64 was dissolved in 980g of deionized water and stirred until completely dissolved to prepare an aqueous solvent with a Pluronic® L-64 content of 2wt%. The previously prepared oily fluid was slowly added to the aqueous solvent under high-speed shearing at 3500rpm, and the mixture was continuously sheared and dispersed for 10 minutes to achieve initial emulsification. Subsequently, the mixture was further processed using an ultrasonic disperser until a uniform, fine, and stable milky-white emulsion was formed. The modified silica spherical particles accounted for 15% of the emulsion, and the mixed oily solvent accounted for 20%.

[0079] A double-ribbed fabric woven from a composite yarn of 300D ultra-high molecular weight polyethylene fiber and polyester fiber was immersed in the treatment emulsion of this embodiment for 30 seconds. Excess treatment emulsion was then squeezed out through rollers, and the fabric was thoroughly dried in an oven to obtain a soft, breathable, needle-punch-resistant, and abrasion-resistant composite material.

[0124] Comparative Example 7:

[0125] The difference from Example 1 is that the mass fraction ratio of paraffin oil to methyl silicone oil in component two is 7:3. Experimental results show that when the proportion of paraffin oil is large, a uniform and stable oily dispersion system cannot be formed, and the nanoparticles are layered in this system, making it impossible to prepare a treatment emulsion.

[0126] Comparative Example 8:

[0127] The difference from Example 1 is that the mass fraction ratio of paraffin oil to methyl silicone oil in component two is 8:2. Experimental results show that when the proportion of paraffin oil is large, a uniform and stable oily dispersion system cannot be formed, and the nanoparticles are layered in this system, making it impossible to prepare a treatment emulsion.

[0128] Comparative Example 9:

The mass fraction ratios of Component 1 and Component 2 in the treated emulsion remain consistent with those in Example 1. The final treated emulsion is prepared by immersing a double-ribbed fabric woven from 300D ultra-high molecular weight polyethylene fiber into the treated emulsion of this comparative example, then squeezing out excess treated emulsion through rollers, and finally drying it thoroughly in an oven to obtain a soft-handed composite material.

[0130] Comparative Example 10:

[0131] The difference from Example 1 is that the mixed oily solvent in Component 2 was replaced with polyether-modified silicone oil and paraffin oil in a mass fraction ratio of 5:5. Experimental results show that polyether-modified silicone oil and paraffin oil have poor compatibility and are difficult to mix to form a uniform and stable oily dispersion system. The nanoparticles are layered in this system, making it impossible to prepare a treatment emulsion.

[0132] Comparative Example 11:

[0133] The difference from Example 1 is that the surfactant in component three is replaced with Span® 80, with an HLB value of 3.3–5.3. Because this HLB value does not match the required hydrophilic-lipophilic equilibrium range of the system, it is a strongly lipophilic emulsifier and cannot form a stable emulsion film at the oil-water interface. This results in poor compatibility between the oil and water phases, extremely poor emulsification, and the inability to prepare a treated emulsion.

[0134] Comparative Example 12:

[0135] The difference from Example 1 is that the surfactant in component three is replaced with sodium dodecyl sulfate (SDS), with an HLB value of 40. Because this HLB value does not match the required hydrophilic-lipophilic equilibrium range of the system, its lipophilicity is extremely weak, making it unable to effectively anchor the methyl silicone oil-paraffin oil mixture. This results in difficulty in forming a stable emulsion film at the oil-water interface, ultimately leading to the incompatibility of the oil and water phases, extremely poor emulsification, and the inability to prepare a treated emulsion.

[0136] Comparative Example 13:

[0137] The difference from Example 1 is that the amount of emulsifier added in component three is 0.1 wt% of the total mass of the aqueous solution. Severe solid-liquid separation occurs in the emulsion, and the oil phase, aqueous phase, and particle components cannot form a uniformly dispersed system. Ultimately, a stable and uniform emulsion cannot be prepared, and subsequent fabric finishing processes cannot be successfully implemented.

[0138] Comparative Example 14:

[0139] The difference from Example 1 is that the amount of component one added is 55g, accounting for 4.8% of the mass fraction in the treated emulsion; the amount of component two added is 40.5g of methyl silicone oil and 40.5g of paraffin oil, accounting for 7.1% of the mass fraction in the treated emulsion. A double-rib fabric woven from 300D ultra-high molecular weight polyethylene fiber was impregnated into the treated emulsion of this comparative example, then excess treated emulsion was squeezed out by rollers, and the fabric was thoroughly dried in an oven to obtain a soft and breathable composite material. The untreated fabric had a basis weight of 460g / m². 2 The fabric composite material has a basis weight of 510 g / m². 2 The mass fraction of oily fluid in the double-ribbed fabric composite material woven from 300D ultra-high molecular weight polyethylene fiber is 9.8%. After the fabric composite material was prepared, it was tested and found to have a needle puncture resistance of 2.04N and an abrasion resistance of 12,000 cycles.

[0140] Comparative Example 15:

[0141] The difference from Example 1 is that the amount of component one added is 551g, accounting for 27.6% of the mass fraction in the treated emulsion; the amount of component two added is 224.5g of methyl silicone oil and 224.5g of paraffin oil, accounting for 22.5% of the mass fraction in the treated emulsion. The particles, oil phase, and aqueous phase components are difficult to form a uniform dispersion system, resulting in extremely poor flowability of the prepared treated emulsion, which makes subsequent fabric finishing processes impossible to carry out smoothly.
