Description

Technical Field

[0001] This application belongs to the field of protective clothing, and specifically relates to a cut- and puncture-resistant fabric, its preparation method, and its application. Background Technology

[0002] With the increasing demand for public safety, personal protective equipment (PPE) is being used more and more widely in military and police law enforcement and civilian security. Ultra-high molecular weight polyethylene (UHMWPE) fiber, due to its excellent specific strength, abrasion resistance, and chemical corrosion resistance, has become the preferred reinforcing fiber for cut and stab-resistant materials. To reduce costs and improve fabric stiffness and dyeing properties while ensuring protective performance, current technologies often use UHMWPE fibers blended, interwoven, or layered with polyester (PET, commonly known as polyester) fibers to construct composite substrates. The fiber structure is then fixed through resin impregnation and hot-pressing processes to prepare flexible stab-resistant composite materials.

[0003] To address the fiber slippage problem in flexible fabrics during stab protection, existing technologies primarily focus on improving the macroscopic adhesion of resin to fibers. Chinese patent CN102788531A discloses a method for preparing a stab-resistant layer using polyurethane resin impregnated with UHMWPE non-woven fabric. This method attempts to use adhesives to solidify loose fiber bundles into a monolithic sheet. Chinese patent CN105544228B attempts to apply a cured resin to the fabric surface using a hot-melt process, aiming to provide localized hardening support while maintaining flexibility.

[0004] Although the aforementioned existing technologies attempt to enhance materials through different resin coating or impregnation methods, in practical applications, especially when hot-pressing UHMWPE / PET blends, insurmountable stability defects remain. Those skilled in the art have found that even with the use of high-adhesion resins and increased hot-pressing pressure, the resulting puncture-resistant materials often exhibit significant dispersion in their puncture resistance values ​​when punctured by sharp objects (such as standard test knives). Particularly after repeated bending, the material is highly prone to premature, abnormal breakage far before reaching the theoretical tensile strength of the fibers. Macroscopic examination reveals that the fibers at the failure sites are not "cut," but rather exhibit large-area loose slippage and pull-out phenomena.

[0005] In summary, although existing technologies have proposed various resin composite processes, they have consistently failed to eliminate the "slippage and premature aging" phenomenon in blended stab-resistant materials during practical use. Therefore, designing a flexible stab-resistant garment that can truly achieve high-strength anchoring and meet tensile strength standards, along with its manufacturing method, is of paramount importance. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides a cut- and stab-resistant fabric, its preparation method, and its application. This cut- and stab-resistant fabric employs a ternary synergistic modified resin system combining "physical barrier-homogeneous fusion-rheological setting" with a stepwise gradient hot-pressing process. This achieves precise reverse control of resin flow behavior within the hot-pressing rheological field of the blended system, forcibly enhancing the microscopic encapsulation rate and interfacial anchoring strength of the resin matrix for inert ultra-high molecular weight polyethylene (UHMWPE) fibers. It solves the problems of resin interfacial depletion and fiber slippage failure during the stab-resistant process caused by "competitive resin segregation" in existing technologies, significantly improving stab resistance while maintaining fabric flexibility.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A cut- and puncture-resistant fabric includes a cut-resistant base fabric and a modified resin matrix impregnated and cured in the interfiber gaps of the cut-resistant base fabric. The cut-resistant base fabric is a composite fabric of ultra-high molecular weight polyethylene (UHMWPE) fibers and polyester fibers. The modified resin matrix contains a ternary synergistic filler system, which consists of a sheet-like flow-blocking agent, a homogeneous fusing agent, and a thixotropic agent. The sheet-like flow-blocking agent is an inorganic filler with a layered structure, and the planar size of the sheet-like flow-blocking agent is larger than the interfiber pore size of the polyester fiber bundle, and it is enriched on the surface of the polyester fibers in a filter cake stacking form. The homogeneous fusing agent is a non-polar thermoplastic polymer micropowder, and the melting point of the homogeneous fusing agent is lower than the melting point of the UHMWPE fibers, and it is bonded to the interface between the UHMWPE fibers and the modified resin matrix in an interfacial crystalline form. The thixotropic agent is nanoparticles capable of forming hydrogen bond networks or van der Waals force networks, uniformly dispersed in the modified resin matrix.

[0009] Furthermore, the sheet-like flow barrier is selected from at least one of organically modified montmorillonite, kaolinite, nano-mica, or sheet-like graphene; the aspect ratio of the sheet-like flow barrier is greater than a set threshold to form a physical barrier layer on the surface of the polyester fiber.

[0010] Furthermore, the homogeneous fusing agent is selected from at least one of low-density polyethylene, linear low-density polyethylene, ultra-low-density polyethylene, or polyethylene wax; the homogeneous fusing agent and the ultra-high molecular weight polyethylene fiber have the same chemical structural units, and the two have molecular chain entanglement or epitaxial co-crystallization structure at the interface.

[0011] Furthermore, the thixotropic agent is selected from at least one of fumed silica, organobentonite, or cellulose nanocrystals; the modified resin matrix has rheological properties of shear thinning and static thickening.

[0012] Furthermore, the modified resin matrix is ​​non-uniformly distributed in the cut-resistant base fabric; wherein, the resin coverage on the surface of the ultra-high molecular weight polyethylene fiber is higher than the resin filling rate inside the polyester fiber bundle.

[0013] Furthermore, the weaving structure of the cut-resistant base fabric is selected from plain weave, twill weave, satin weave, or multiaxial warp knitting; the main resin of the modified resin matrix is ​​selected from one or more of waterborne polyurethane, polyacrylate, or ethylene-vinyl acetate copolymer emulsion.

[0014] The present invention also provides a method for preparing the above-mentioned cut- and puncture-resistant fabric, comprising the following steps: S1. Preparation of modified prepreg slurry: The flake-like flow barrier, thixotropic agent, and homogeneous flux are dispersed in a resin matrix to obtain a slurry with pseudoplastic fluid characteristics; S2. Preparation of prepreg: The cut-resistant base fabric is immersed in the modified prepreg slurry, and after extrusion impregnation and pre-drying, the resin is in a semi-cured state; S3. Gradient hot pressing molding: At least one layer of the prepreg is placed in a mold for stepwise hot pressing; The stepwise hot pressing includes a first hot pressing stage and a second hot pressing stage; In the first hot pressing stage, the temperature is set below the melting point of the homogeneous flux, and the pressure is set to a first pressure, so that the flake-like flow barrier is deposited on the surface of the polyester fiber; In the second hot pressing stage, the temperature is set above the melting point of the homogeneous flux and below the melting point of the ultra-high molecular weight polyethylene fiber, and the pressure is set to a second pressure, so that the homogeneous flux melts and wets the ultra-high molecular weight polyethylene fiber; Wherein, the first pressure is higher than the second pressure.

[0015] Furthermore, in step S1, the preparation process of the modified prepreg slurry includes: first, adding the flake-shaped flow barrier dispersion to the resin matrix and mixing it; then, adding the thixotropic agent for high-shear dispersion; and finally, adding the homogeneous fusing agent in solid particulate form and mixing it uniformly at low speed.

[0016] Furthermore, in step S3: the first hot pressing stage maintains the homogeneous flux in a solid particle state, and uses the first pressure to drive the resin flow and compact the sheet-like flow barrier; the second hot pressing stage induces a phase change in the homogeneous flux, and uses the second pressure to maintain the wetting and spreading of the resin matrix on the surface of the ultra-high molecular weight polyethylene fiber, while preventing the molten homogeneous flux from being squeezed out of the interface; after hot pressing, it is cooled to below the setting temperature under pressure holding.

[0017] This invention also provides an application of cut- and stab-resistant fabric in cut- and stab-resistant clothing, comprising the following steps: S1. Preparation and pretreatment of blended substrate: Fabrics made of blended, interwoven, or laminated ultra-high molecular weight polyethylene fiber and polyester fiber are selected as cut-resistant base fabrics. S2. Formulation of ternary synergistic functionalized rheology paste: A ternary filler system comprising a flow barrier, a thixotropic agent, and a homogeneous fusing agent was constructed using waterborne thermoplastic polyurethane emulsion as the matrix resin. First, the flow barrier agent is dispersed in a solvent to form a suspension, which is then added to the matrix resin and mixed. Secondly, a thixotropic agent is added and dispersed at a high shear rate until the slurry exhibits pseudoplastic fluid characteristics; Finally, a homogeneous fusing agent is added and dispersed evenly to obtain the modified prepreg slurry; The flow-blocking agent is used to construct a filter cake layer on the surface of the polyester fiber, the homogeneous bonding agent is used to form an interface weld with the ultra-high molecular weight polyethylene fiber, and the thixotropic agent is used to lock the resin distribution. S3. Pre-impregnation treatment under pressure control: The cut-resistant base fabric is immersed in the modified prepreg slurry, the amount of adhesive is controlled, and then pre-drying treatment is performed to make the resin in a semi-cured state to obtain the prepreg. S4. Step-by-step gradient hot pressing molding: The multiple layers of the prepreg are stacked and placed in a mold for at least two stages of programmed hot pressing; Phase 1 is the low-temperature high-pressure flow-blocking dam-building phase: the hot-pressing temperature is set to T1, which is lower than the melting point of the homogeneous flux, and high pressure P1 is applied to force the flow-blocking agent to accumulate on the surface of the polyester fiber bundle. Phase 2 is the high-temperature and low-pressure homogeneous fusion stage: the hot-pressing temperature is set to T2, which is higher than the melting point of the homogeneous fusion agent. The pressure is reduced to P2, so that the homogeneous fusion agent melts and wets the surface of the ultra-high molecular weight polyethylene fiber. Phase three is the thixotropic locking cooling and shaping phase: maintaining pressure P2, cooling to below the shaping temperature and then opening the mold to obtain the puncture-resistant composite material.

[0018] Furthermore, in step S1, the mass ratio of ultra-high molecular weight polyethylene fiber to polyester fiber is (5-9):(1-5). The weaving structure of the cut-resistant base fabric is selected from any one of plain weave, twill weave, satin weave, or multi-axial warp knitting structure.

[0019] Furthermore, in step S2, the matrix resin may also be selected from one or more of waterborne polyurethane (WPU), ethylene-vinyl acetate copolymer (EVA) emulsion, polyacrylate (PA) emulsion, or styrene-butadiene latex; the solid content of the matrix resin is 35%-55%.

[0020] Furthermore, the flow-blocking agent is selected from sheet-like inorganic fillers with a high aspect ratio, including one or more of organically modified montmorillonite, kaolinite, nano-mica, sheet-like graphene, or graphene oxide. Preferably, it is organically modified montmorillonite with an aspect ratio greater than 200 and a sheet diameter of 200-1000 nm.

[0021] Furthermore, the amount of the flow-blocking agent added is 2.0wt%-8.0wt% of the total weight of the slurry, preferably 3.0wt%-5.0wt%. This range is designed because: below 2.0wt%, it is difficult to form a continuous filter cake layer, and above 8.0wt%, it will lead to increased brittleness of the filter cake layer.

[0022] Furthermore, the homogeneous flux is selected from non-polar polyolefin micropowders with a melting point of 90-115℃, including one or more of low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE), ultra-low-density polyethylene (VLDPE), or polyethylene wax micropowder. The average particle size of the homogeneous flux is 5-20 μm.

[0023] Furthermore, the amount of the homogeneous fusing agent added is 3.0wt%-10.0wt% of the total weight of the slurry, preferably 5.0wt%-8.0wt%.

[0024] Furthermore, the thixotropic agent is selected from hydrophilic fumed silica, organobentonite, or cellulose nanocrystals, preferably with a specific surface area of ​​150-300 m². 2 / g of hydrophilic fumed silica; the addition amount is 0.5wt%-3.0wt% of the total weight of the slurry.

[0025] Furthermore, in step S3, the amount of adhesive is controlled at 25wt%-45wt%, the pre-drying temperature is 70-90℃, and the time is 3-8 minutes, to ensure that the surface of the prepreg is not sticky and the resin is not completely cross-linked.

[0026] Furthermore, in the gradient hot pressing process of step S4, the process parameters are controlled as follows: Stage 1: Temperature T1 is 80-100℃, pressure P1 is 5-10 MPa, and pressure holding time is 1-5 minutes; Phase 2: Temperature T2 is 115-135℃, pressure P2 is 1-5 MPa, and pressure holding time is 2-6 minutes; The temperature T2 is set to be 10-25°C higher than the melting point of the homogeneous flux and lower than the melting point of ultra-high molecular weight polyethylene fiber.

[0027] Furthermore, the technical problem to be solved by the present invention, its causes, and the principle of its solution are detailed below: 1. Technical problems to be solved: The present invention aims to solve the problem of competitive resin segregation and the resulting UHMWPE interface depletion failure in the preparation of stab-resistant materials by hot pressing of UHMWPE / PET blended systems in the prior art.

[0028] 2. Reasons for the problem: The applicant discovered in its microscopic failure analysis that the root cause of the aforementioned problem lies in a dual mismatch between thermodynamics and kinetics within the thermo-compression rheological field. Thermodynamically, PET fibers possess high surface energy and polarity, exhibiting a natural affinity for polar resins, while UHMWPE has extremely low surface energy and is chemically inert, causing liquid resin to spontaneously flow towards higher-energy surfaces. Kinetically, the micron-sized capillary channels within the PET multifilament fiber bundles generate strong capillary suction, actively drawing in low-viscosity resin. Under these dual effects, the resin matrix undergoes selective migration, becoming excessively enriched within the PET fiber bundles. This results in severe resin depletion on the surface of the crucial puncture-resistant UHMWPE fiber skeleton, preventing effective interfacial stress transfer.

[0029] 3. The principle by which this invention solves the problem: This invention constructs a triple synergistic mechanism of physical barrier, homogeneous fusion, and rheological shaping.

[0030] The first layer is a physical barrier mechanism: utilizing the size sieving effect generated by the high aspect ratio sheet-like flow barrier. When the resin attempts to flow into the PET, the large-sized sheets become stuck at the pore entrance, bridging and forming a dense filter cake barrier layer, physically cutting off the resin's entry into the PET interior and forcing the resin to flow back to the UHMWPE interface.

[0031] The second mechanism is homogeneous fusion: interfacial welding is achieved using a homogeneous fusion agent. Non-polar micropowders are thermodynamically incompatible with PET, forcing them to spread on the UHMWPE surface. Based on the principle of homogeneous self-diffusion, the chemically similar melt and UHMWPE fibers undergo molecular chain entanglement and epitaxial co-crystallization at the interface, forming strong anchoring points.

[0032] The third mechanism is rheological shaping: using thixotropic agents to construct hydrogen-bonded cabin structures. At the moment the hot pressing ends and the shear force disappears, the resin viscosity rises sharply, freezing the microstructure and preventing secondary migration of the resin during cooling.

[0033] The present invention has the following beneficial effects: 1. This invention solves the problem of hidden resin segregation in blended stab-resistant materials. By introducing a flake-shaped flow barrier to generate a filter cake effect, the excessive migration of resin to PET fibers is successfully blocked, increasing the resin coverage on the UHMWPE surface from less than 10% in the prior art to over 90%.

[0034] 2. This invention utilizes the principle of homogeneous fusion to achieve welding between resin and inert fibers using low-melting-point non-polar micropowder without altering the chemical properties of UHMWPE. This micropowder automatically avoids PET using thermodynamic repulsion and precisely anchors itself on the UHMWPE surface, significantly improving its pull-out resistance.

[0035] 3. The gradient hot-pressing process and formulation system adopted in this invention. In the low-temperature, high-pressure stage, a flow-blocking agent is compacted under high pressure to form a dam, while in the high-temperature, low-pressure stage, low pressure is used to prevent the molten micro-powder from being extruded. The two stages of the process do not interfere with each other. The resulting stab-resistant garment maintains softness and comfort while meeting the GA 68-2019 standard for stab resistance, achieving a high degree of unity between flexibility and protection.

[0043] Example 1: The above-mentioned UHMWPE / PET blended fabric was used as the target substrate and prepared using the following method. The formulation and process parameters are shown in Table 1, and the test results are shown in Table 2.

[0044] 1) Preparation of functionalized slurry: Add 4.0g of flake organic modified montmorillonite (flow barrier agent) to 100g of deionized water and ultrasonically disperse for 30 minutes; slowly add the above dispersion to 100g of WPU resin (matrix) and stir at low speed for 20 minutes; then add 1.5g of fumed silica (thixotropic agent) and shear at high speed (2000rpm) for 10 minutes until the slurry exhibits pseudoplastic characteristics; finally add 6.0g of ultrafine low melting point polyethylene powder (fusible agent) and disperse evenly at low speed to obtain prepreg slurry with a viscosity of 2500-3500 mPa.s.

[0045] 2) Pre-impregnation treatment: Immerse the base fabric in the slurry obtained in step 1, control the adhesive amount (pick-uprate) to 35±2 wt% by rollers, and then pre-dry it in an 80℃ oven for 5 minutes to obtain a semi-cured prepreg.

[0046] 3) Gradient hot pressing: Four layers of prepreg are stacked and placed in a flatbed hot press.

[0047] Phase 1 (Dam Construction): Temperature set to 90℃, pressure 8 MPa, maintained for 2 minutes. In this phase, high pressure drives resin flow, and flake montmorillonite forms a filter cake barrier layer on the surface of PET fibers.

[0048] Stage Two (Fusion): Rapidly heat to 120°C, reduce pressure to 3 MPa, and maintain for 3 minutes. In this stage, L-PE micropowder melts and preferentially wets UHMWPE fibers, resulting in homogeneous fusion.

[0050] Examples 2-5 and Comparative Examples 1-4: The preparation methods of Examples 2-5 and Comparative Examples 1-4 are basically the same as those of Example 1, except that the amount and type of each component added to the slurry and the temperature (T2) of the second hot pressing stage are different. For specific parameter settings, please refer to Table 1.

[0052]

[0057] 4) Bending stiffness: Tested using the cantilever beam method; the smaller the value, the more flexible the material.

[0058] Table 2 Performance test results of each embodiment and comparative example

[0059] Results analysis: As can be seen from the data in Table 2, the method of the present invention significantly solves the problem of resin segregation in the blended system: 1) Verification of defects in existing technology: Comparative Example 1 simulated a conventional blending process. The resin coverage on the UHMWPE surface was less than 10%, and it penetrated through 9 layers during puncture resistance, resulting in large-area slippage. This confirms that during hot pressing, the resin does indeed tend to flow towards the oleophilic PET fibers, leading to poor resin content at the UHMWPE fiber interface.

[0060] 2) Advantages of the best mode of the present invention: In Example 1, the resin coverage is increased to 92% through the synergistic effect of flake montmorillonite and L-PE micro powder, the peel strength is nearly 3 times that of the prior art, and the puncture resistance is significantly improved (only 3 layers are penetrated).

[0061] 3) The crucial role of filler shape: In Comparative Example 2, replacing the sheet filler with spherical filler resulted in a sharp drop in coverage. This indicates that only sheet fillers with a high aspect ratio can create a bridging effect between PET fibers, while spherical fillers cannot block resin penetration into PET.

[0062] 4) The necessity of polarity matching: Comparative Example 4 used polar EVA micropowder, which resulted in low resin coverage. This is because the polar micropowder was attracted by the high surface energy of PET in the molten state, accelerating the migration of resin to PET. This conversely proves that only by using pure non-polar PE micropowder, taking advantage of its thermodynamic incompatibility with PET, can it be forced to remain on the UHMWPE surface to achieve homogeneous fusion.

[0063] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
