Description

Technical Field

[0001] This invention relates to the field of nonwoven fabric technology, and in particular to a nonwoven fabric with a cut-resistant structure. Background Technology

[0002] Through different processes, non-woven fabrics can acquire functions such as moisture resistance, breathability, flexibility, and flame retardancy, thereby expanding their application scenarios. Non-woven fabrics are often used as the surface or bottom layer of composite structures for bags and protective clothing. Cut-resistant non-woven fabrics in protective clothing can prevent workers from being cut by sharp objects, while cut-resistant non-woven fabrics in bags can improve the durability and cut resistance of bags. These are effects that ordinary non-woven fabrics cannot provide.

[0003] Based on the above, in the prior art, patent CN216891418U discloses a nonwoven fabric with a cut-resistant structure, including a first nonwoven fabric layer and a second nonwoven fabric layer, with a cut-resistant structure layer provided between the first nonwoven fabric layer and the second nonwoven fabric layer. The cut-resistant structure layer includes an elastic layer and several parallel elastic strips, with a buffer groove formed between two adjacent elastic strips. A buffer block adapted to the shape of the buffer groove is provided in the buffer groove, and the buffer block includes several protective layers. Elastic rubber particles are filled between two adjacent protective layers.

[0004] The aforementioned nonwoven fabric, through the cooperation of components such as cut-resistant lines, buffer grooves, buffer blocks, protective layers, and elastic strips, enables a sharp object to cut into the nonwoven fabric along the length of the elastic strip and perpendicular to the length of the elastic strip. However, the aforementioned nonwoven fabric still has some shortcomings in terms of cut resistance. The protective layer and elastic strip are set at intervals, and the cut resistance performance of the elastic strip is weaker than that of the protective layer. The sharp object may cut into the elastic strip between the two cut-resistant lines, which may lead to a decrease in cut resistance performance. At the same time, the aforementioned nonwoven fabric does not have puncture resistance in its structure, and the nonwoven fabric cannot effectively prevent the insertion of the sharp part of the sharp object. Summary of the Invention

[0005] To address the technical deficiencies in the background art, this invention proposes a nonwoven fabric with a cut-resistant structure. To further solve the aforementioned technical problems and meet practical needs, the specific technical solution is as follows:

[0006] A nonwoven fabric with a cut-resistant structure includes a surface nonwoven fabric, a cut-resistant layer, and a bottom nonwoven fabric. The surface nonwoven fabric covers the upper surface of the cut-resistant layer, and the bottom nonwoven fabric covers the lower surface of the cut-resistant layer. The cut-resistant layer includes a cut-resistant base layer and a woven layer, which are nested together. The cut-resistant base layer has several puncture-resistant sheets on its surface, and several evenly distributed first fixing holes are provided on the surface of each puncture-resistant sheet. The cut-resistant base layer has several second fixing holes between adjacent puncture-resistant sheets. The woven layer includes several transverse composite fibers and several longitudinal composite fibers. The transverse composite fibers and longitudinal composite fibers pass through the first fixing holes of the puncture-resistant sheets and the second fixing holes of the cut-resistant base layer in a crisscross weave.

[0007] The method for preparing the nonwoven fabric with the anti-cutting structure includes the following steps:

[0008] A mixed coating is prepared by mixing organosilane resin and antibacterial agent. The mixed coating is applied to the surface of glass fiber to obtain composite glass fiber. The composite glass fiber is interwoven to obtain a cut-resistant base layer. A positioning groove is formed by drilling holes in the surface of the cut-resistant base layer. A second fixing hole is formed by drilling holes between adjacent positioning grooves on the surface of the cut-resistant base layer.

[0009] Take the cured resin strip, cut the resin strip into a specified diameter using a molding device, slice the resin strip to obtain a puncture-resistant sheet, and punch holes in the surface of the puncture-resistant sheet to form the first fixing hole;

[0010] The anti-stab sheet is placed in the positioning groove, and the transverse composite fiber and the longitudinal composite fiber are sequentially passed through the first fixing hole of the anti-stab sheet and the second fixing hole of the anti-cut base layer in a crisscross weave to obtain the anti-cut layer.

[0011] The surface nonwoven fabric is bonded to the upper surface of the cut-resistant layer by an adhesive, and the bottom nonwoven fabric is bonded to the lower surface of the cut-resistant layer to obtain a nonwoven fabric with a cut-resistant structure.

[0012] Furthermore, the transverse composite fiber and the longitudinal composite fiber are formed by twisting ultra-high molecular weight polyethylene fiber and carbon fiber, the ratio of ultra-high molecular weight polyethylene fiber to carbon fiber is 1:1-3, and the diameter of the transverse composite fiber and the longitudinal composite fiber is 0.01-0.05 mm.

[0013] Furthermore, the stab-resistant sheet is made of any one of epoxy resin, unsaturated resin, or polyurethane resin, and the thickness of the stab-resistant sheet is 0.1-0.5 mm, and the diameter of the stab-resistant sheet is 1-5 mm.

[0014] Furthermore, the puncture-resistant sheets are arranged in a rectangular row on the surface of the cut-resistant base layer, with a spacing of 3-5 mm between adjacent puncture-resistant sheets.

[0015] Furthermore, the second fixing holes are arranged in a rectangular row on the stab-proof sheet, and the diameter of each second fixing hole is 0.05-0.1mm, with a spacing of 1-2mm between adjacent second fixing holes.

[0016] Further, the organosilane resin is any one of phenylmethyl polysiloxane resin or methylsilane resin, the antibacterial agent is nano-silver particles, the coating thickness of the mixed coating on the glass fiber is 0.01-0.03 mm, and the diameter of the glass fiber is 0.05-0.5 mm.

[0017] Furthermore, the diameter of the first fixing hole is 0.05-0.1 mm, and the distance between adjacent first fixing holes is 1-2 mm.

[0018] Beneficial effects of this invention:

[0019] The cut-resistant base layer and the woven layer are nested and woven together to form the cut-resistant layer, giving the nonwoven fabric excellent cut-resistant and puncture-resistant properties. The puncture-resistant sheet on the surface of the cut-resistant base layer can effectively resist the penetration of sharp objects. The first fixing hole evenly distributed on the surface of the puncture-resistant sheet and the second fixing hole between adjacent puncture-resistant sheets on the cut-resistant base layer, along with the woven layer, provide stable fixing points. This allows the transverse and longitudinal composite fibers to fix the puncture-resistant sheet to the surface of the cut-resistant base layer through the first and second fixing holes, preventing the puncture-resistant sheet from falling off during use. This improves the cut-resistant, puncture-resistant properties and durability of the nonwoven fabric. The cut-resistant base layer is made of composite glass fiber woven together, which can further increase the cut-resistant properties of the nonwoven fabric. Attached Figure Description

[0023] like Figs. 1-2As shown, the present invention provides a technical solution: a nonwoven fabric with a cut-resistant structure, comprising a surface nonwoven fabric 1, a cut-resistant layer 2, and a bottom nonwoven fabric 3. The surface nonwoven fabric 1 covers the upper surface of the cut-resistant layer 2, and the bottom nonwoven fabric 3 covers the lower surface of the cut-resistant layer 2. The cut-resistant layer 2 comprises a cut-resistant base layer 23 and a woven layer 24, which are nested together. The cut-resistant base layer 23 has a plurality of puncture-resistant sheets 26 on its surface, and a plurality of evenly distributed first fixing holes 261 on the surface of the puncture-resistant sheets 26. The cut-resistant base layer 23 has a plurality of second fixing holes 231 between adjacent puncture-resistant sheets 26. The woven layer 24 comprises a plurality of transverse composite fibers 21 and a plurality of longitudinal composite fibers 22. The transverse composite fibers 21 and longitudinal composite fibers 22 pass sequentially through the first fixing holes 261 of the puncture-resistant sheets 26 and the second fixing holes 231 of the cut-resistant base layer 23 in a crisscross woven form.

[0024] The present invention adopts a three-layer structure design consisting of a surface non-woven fabric 1, a cut-resistant layer 2, and a bottom non-woven fabric 3. The cut-resistant layer 2 is the main load-bearing layer. The multi-layer protection design enables the non-woven fabric to form multiple lines of defense when attacked by sharp objects. The multi-layer structure also increases the thickness and density of the non-woven fabric, improving its cut and puncture resistance. The nested weaving of the cut-resistant base layer 23 and the woven layer 24 makes the non-woven fabric more structurally stable and enhances its overall cut resistance. The braided layer 24 forms a robust network structure through the interlacing of transverse composite fibers 21 and longitudinal composite fibers 22, thereby improving the tensile and tear resistance of the material. The stab-resistant sheet 26 and its first fixing hole 261 on the cut-resistant base layer 23, as well as the second fixing hole 231 between adjacent stab-resistant sheets 26, provide stable fixing points for the transverse composite fibers 21 and longitudinal composite fibers 22 of the braided layer 24, making the braided layer 24 fit more tightly to the cut-resistant base layer 23, enhancing the overall strength and stability of the nonwoven fabric. At the same time, the stab-resistant sheet 26 can directly resist the penetration of sharp objects, further improving the stab resistance of the nonwoven fabric.

[0025] The uniform distribution of the first fixing hole 261 and the second fixing hole 231 ensures that the fibers of the braided layer 24 are evenly distributed throughout the cut-resistant layer 2, which helps to maintain the material's balanced strength and protective performance. The transverse composite fibers 21 and longitudinal composite fibers 22 of the braided layer 24 pass through the first fixing hole 261 and the second fixing hole 231 in a cross-woven form, thereby increasing the strength and toughness of the nonwoven fabric in the structure. It also enables the nonwoven fabric to evenly distribute stress when subjected to external forces, reducing the situation of excessive local stress, and further improving its cut-resistant and puncture-resistant performance.

[0026] In a preferred embodiment of the present invention, the transverse composite fiber 21 and the longitudinal composite fiber 22 are formed by twisting ultra-high molecular weight polyethylene fiber and carbon fiber, the ratio of ultra-high molecular weight polyethylene fiber to carbon fiber is 1:1-3, and the diameter of the transverse composite fiber 21 and the longitudinal composite fiber 22 is 0.01-0.05 mm.

[0027] Ultra-high molecular weight polyethylene (UHMWPE) fiber and carbon fiber have high specific strength and specific modulus. By twisting carbon fiber and UHMWPE fiber together to form transverse composite fiber 21 and longitudinal composite fiber 22, the fiber can provide greater tensile strength and rigidity, thereby enhancing the cut resistance and puncture resistance of nonwoven fabric. At the same time, UHMWPE fiber has the characteristics of low elongation at break and high breaking energy, which can absorb the downward pressure of sharp objects when cutting nonwoven fabric to a certain extent. Combined with the strength and rigidity of carbon fiber, transverse composite fiber 21 and longitudinal composite fiber 22 can effectively disperse and absorb energy when subjected to impact or cutting, thereby improving the impact resistance and cut resistance of nonwoven fabric.

[0028] The specific ratio of ultra-high molecular weight polyethylene fiber to carbon fiber is 1:3. Increasing the amount of carbon fiber can ensure the good flexibility and weavability of the transverse composite fiber 21 and the longitudinal composite fiber 22, while maintaining the strength of the nonwoven fabric and reducing its overall weight. The diameter of the transverse composite fiber 21 and the longitudinal composite fiber 22 is 0.05mm, which can form a tight woven structure, further enhancing the protective performance of the nonwoven fabric. By passing the transverse composite fiber 21 and the longitudinal composite fiber 22 through the first fixing hole 261 of the puncture-resistant sheet 26 and the second fixing hole 231 of the cut-resistant base layer 23 in a cross-woven form, a stable structural network is formed, which can enhance the overall stability and durability of the nonwoven fabric, enabling it to maintain excellent protective performance in various environments.

[0029] In a preferred embodiment of the present invention, the stab-resistant sheet 26 is made of any one of epoxy resin, unsaturated resin, and polyurethane resin, the thickness of the stab-resistant sheet 26 is 0.1-0.5 mm, and the diameter of the stab-resistant sheet 26 is 1-5 mm.

[0030] The presence of the stab-resistant sheet 26 is equivalent to adding multiple small protective shields to the non-woven fabric, which can effectively block or slow down the penetration of sharp objects, thereby improving the stab-resistant performance of the non-woven fabric. The stab-resistant sheet 26 is made of epoxy resin, unsaturated resin, or polyurethane resin, preferably epoxy resin, with a Shore hardness range of 50-70. Epoxy resin, unsaturated resin, and polyurethane resin are all polymer materials with good physical and chemical stability. The stab-resistant sheet 26 can provide effective protection against the puncture of sharp objects. The stab-resistant sheet 26 is 0.1 mm thick and 2 mm in diameter. This size allows the stab-resistant sheet 26 to maintain strength without excessively increasing the thickness and weight of the non-woven fabric, thus allowing the non-woven fabric to maintain excellent protective performance while still having good softness and comfort.

[0031] like Fig. 2 As shown, in a preferred embodiment of the present invention, the puncture-resistant sheets 26 are arranged in a rectangular row on the surface of the cut-resistant base layer 23, and the spacing between adjacent puncture-resistant sheets 26 is 3-5 mm.

[0032] The rectangular alignment ensures that the stab-resistant sheets 26 are evenly distributed on the cut-resistant base layer 23, forming a dense protective network that maximizes the coverage of the cut-resistant base layer 23 surface. The rectangular alignment also creates a stable structural skeleton for the stab-resistant sheets 26 within the nonwoven fabric, enhancing its tensile and tear resistance. The rectangular alignment design makes the arrangement of the stab-resistant sheets 26 on the cut-resistant base layer 23 more regular, simplifying the processing and manufacturing of the nonwoven fabric. The distance between adjacent stab-resistant sheets 26 is 3mm, which ensures sufficient space for the transverse composite fibers 21 and longitudinal composite fibers 22 of the braided layer 24 to pass through and fix the stab-resistant sheets 26, while also ensuring sufficient contact area between the stab-resistant sheets 26 to improve overall stab resistance. At the same time, this spacing reduces the density of the nonwoven fabric, thereby improving its breathability and wearing comfort.

[0033] like Fig. 2 As shown, in a preferred embodiment of the present invention, the second fixing holes 231 are arranged in a rectangular row on the anti-stab sheet 26, and the diameter of each second fixing hole 231 is 0.05-0.1mm, and the spacing between adjacent second fixing holes 231 is 1-2mm; the diameter of the first fixing holes 261 is 0.05-0.1mm, and the spacing between adjacent first fixing holes 261 is 1-2mm.

[0034] The first fixing hole 261 and the second fixing hole 231 are used to cooperate with the transverse composite fiber 21 and the longitudinal composite fiber 22. The transverse composite fiber 21 and the longitudinal composite fiber 22 are woven together through the first fixing hole 261 and the second fixing hole 231 to form a mesh structure, which is evenly inserted between the cut-resistant base layer 23, while fixing the puncture-resistant sheet 26 in the positioning groove 25 of the cut-resistant base layer 23.

[0035] Specifically, the diameters of the second fixing hole 231 and the first fixing hole 261 are both set at 0.2 mm, ensuring that the transverse composite fibers 21 and the longitudinal composite fibers 22 of the braided layer 24 can pass tightly through the second fixing hole 231 and the first fixing hole 261 to form a stable braided structure. The spacing between adjacent second fixing holes 231 and first fixing holes 261 is 2 mm, which makes the arrangement of the second fixing holes 231 and the first fixing holes 261 between the cut-resistant layer 2 more orderly, facilitating the braiding of the transverse composite fibers 21 and the longitudinal composite fibers 22. The tight and orderly braided structure enhances the interaction and friction between the transverse composite fibers 21 and the longitudinal composite fibers 22 and the puncture-resistant sheet 26 and the cut-resistant base layer 23 when the nonwoven fabric is cut or punctured, thereby improving the cut-resistant and puncture-resistant performance of the nonwoven fabric.

[0036] The design of the second fixing hole 231 and the first fixing hole 261 allows the fibers to be evenly distributed on the cut-resistant base layer 23 and the puncture-resistant sheet 26, forming a uniform protective network that effectively prevents the penetration of sharp objects. The second fixing hole 231 and the first fixing hole 261 increase the density of the nonwoven fabric, but by adjusting the spacing and distribution density of the puncture-resistant sheet 26, the nonwoven fabric still maintains a certain degree of breathability, making it more comfortable to wear or use nonwoven products.

[0037] The present invention also provides a method for preparing the above-mentioned nonwoven fabric with a cut-resistant structure, comprising the following steps:

[0038] A mixed coating is obtained by mixing organosilane resin and antibacterial agent. The mixed coating is applied to the surface of glass fiber to obtain composite glass fiber. The composite glass fiber is interwoven to obtain a cut-resistant base layer 23. A positioning groove 25 is formed by drilling holes on the surface of the cut-resistant base layer 23. A second fixing hole 231 is formed by drilling holes between adjacent positioning grooves 25 on the surface of the cut-resistant base layer 23.

[0039] Take the cured resin strip, cut the resin strip into a specified diameter size through molding equipment, slice the resin strip to obtain a puncture-resistant sheet 26, and punch holes in the surface of the puncture-resistant sheet 26 to form the first fixing hole 261.

[0040] Place the anti-stab sheet 26 in the positioning groove 25, and pass the transverse composite fiber 21 and the longitudinal composite fiber 22 through the first fixing hole 261 of the anti-stab sheet 26 and the second fixing hole 231 of the anti-cut base layer 23 in a crisscross weaving pattern to obtain the anti-cut layer 2.

[0041] The surface nonwoven fabric 1 is bonded to the upper surface of the cut-resistant layer 2 using an adhesive, and the bottom nonwoven fabric 3 is bonded to the lower surface of the cut-resistant layer 2 to obtain a nonwoven fabric with a cut-resistant structure.

[0042] In a preferred embodiment of the present invention, the organosilane resin is any one of phenylmethyl polysiloxane resin or methylsilane resin, the antibacterial agent is nano-silver particles, the coating thickness of the mixed coating on the glass fiber is 0.01-0.03 mm, and the diameter of the glass fiber is 0.05-0.5 mm.

[0043] Phenylmethyl polysiloxane resin or methylsilane resin is used as the organosilane resin, preferably phenylmethyl polysiloxane resin. Both resins possess excellent weather resistance, high-temperature resistance, and chemical corrosion resistance. They provide a stable protective layer, enhancing the durability and service life of the nonwoven fabric. Nano-silver particles exhibit excellent antibacterial properties, effectively inhibiting bacterial growth. Adding nano-silver particles to the nonwoven fabric imparts antibacterial functionality, improving the product's hygiene and safety.

[0044] The coating thickness of the mixed coating on the glass fiber is controlled at 0.01 mm. Spraying can be used to ensure that the coating fully covers the surface of the glass fiber to form an effective protective layer, while avoiding excessive coating thickness that would increase the overall thickness of the nonwoven fabric and reduce its flexibility. The diameter of the glass fiber is set at 0.05 mm to ensure that the glass fiber has sufficient strength and toughness, maintains good flexibility and weavability, and at the same time helps to control the thickness and weight of the nonwoven fabric to meet the needs of different application scenarios. By passing the transverse composite fiber 21 and the longitudinal composite fiber 22 through the first fixing hole 261 of the puncture-resistant sheet 26 and the second fixing hole 231 of the cut-resistant base layer 23 in a cross-woven form, a cut-resistant layer 2 with stable structure and high strength can be obtained.

[0045] Example 1

[0046] Phenylmethyl polysiloxane resin and nano silver particles are mixed at a ratio of 100:0.01 to form a mixed coating. The mixed coating is then applied to the surface of a 0.05 mm diameter glass fiber and dried at 80°C to obtain a composite glass fiber. The composite glass fiber is then interwoven to obtain a cut-resistant base layer 23. Holes are drilled in the surface of the cut-resistant base layer 23 to form positioning grooves 25 with a diameter of 2 mm. Holes are drilled between adjacent positioning grooves 25 in the surface of the cut-resistant base layer 23 to form second fixing holes 231 with a diameter of 0.2 mm.

[0047] Take the cured resin strip, cut the resin sleeve into strip columns with a diameter of 2mm using a molding device, slice the resin strip to obtain a puncture-resistant sheet 26 with a thickness of 0.1mm and a diameter of 2mm, and punch holes in the surface of the puncture-resistant sheet 26 to form a first fixing hole 261 with a diameter of 0.2mm.

[0048] Place the anti-stab sheet 26 in the positioning groove 25, and pass the transverse composite fiber 21 and the longitudinal composite fiber 22 through the first fixing hole 261 of the anti-stab sheet 26 and the second fixing hole 231 of the anti-cut base layer 23 in a crisscross weaving pattern to obtain the anti-cut layer.

[0049] The surface nonwoven fabric 1 is bonded to the upper surface of the cut-resistant layer 2 using hot melt adhesive, and the bottom nonwoven fabric 3 is bonded to the lower surface of the cut-resistant layer 2 to obtain a nonwoven fabric with a cut-resistant structure.

[0050] Comparative Example 1

[0051] The difference between Comparative Example 1 and Example 1 is that the anti-puncture sheet 26 is not embedded in the surface of the anti-cut base layer 23, and the first fixing hole 261 is directly drilled on the surface of the anti-cut base layer 23. The other process methods and parameters are the same as those in Example 1.

[0052] Comparative Example 2

[0053] The difference between Comparison 2 and Example 1 is that the composite glass fiber is replaced with glass fiber, while the rest of the process methods and parameters are the same as in Example 1.

[0054] Comparative Example 3

[0055] The difference between Comparative Example 3 and Example 1 is that the distance between adjacent anti-stab sheets 26 is set to 5mm, while the other process methods and parameters are the same as in Example 1.

[0056] Test methods

[0057] The quasi-static puncture resistance test was conducted according to standard GA 68—2003, and the cut resistance test was conducted according to standard BSEN388. The flexibility test was conducted according to INDA IST 90.3. The test results are shown in the table below.

[0058]

[0059] Regarding puncture resistance, the cut-resistant layer in Example 1, due to the embedded puncture-resistant sheet 26, achieved a quasi-static maximum puncture resistance of 102.1 N, significantly higher than Comparative Example 1 (52.4 N), Comparative Example 2 (80.2 N), and Comparative Example 3 (93.7 N). This indicates that the addition of the puncture-resistant sheet 26 effectively improved the puncture resistance of the material. Comparative Example 1, without embedded puncture-resistant sheets, exhibited significantly poorer puncture resistance, demonstrating that the puncture-resistant sheet is a key factor in enhancing puncture resistance. Comparative Example 2, using pure glass fiber instead of composite glass fiber, showed a decrease in puncture resistance, indicating that composite glass fiber is superior to pure glass fiber in puncture resistance. Although Comparative Example 3 also incorporated puncture-resistant sheets, the larger spacing (5 mm) between the sheets resulted in slightly lower puncture resistance than Example 1, indicating that the density of the puncture-resistant sheet distribution also affects puncture resistance.

[0060] Regarding cut resistance, Example 1 achieved a cut resistance index of 20, which was significantly higher than Comparative Examples 1, 2, and 3. This indicates that the cut-resistant layer formed by embedding anti-puncture sheets and interlacing composite glass fibers can effectively improve the material's cut resistance. Comparative Example 1 had the worst cut resistance due to the absence of anti-puncture sheets. Comparative Example 2, which used pure glass fibers, also had poor cut resistance compared to composite glass fibers. Comparative Example 3, due to the larger spacing between the anti-puncture sheets, had slightly lower cut resistance than Example 1.

[0061] Regarding softness, Example 1 had a softness of 5.9g, which was higher than Comparative Example 1 (4.1g) and Comparative Example 2 (5.1g). The addition of the puncture-resistant sheet and composite glass fiber increased the hardness of the material, thereby reducing the softness. Comparative Example 1 had the best softness because it did not have the puncture-resistant sheet. Comparative Example 2 used pure glass fiber, and its softness was slightly lower than that of Example 1, but still higher than that of Comparative Example 3. This shows that while the composite glass fiber improves the puncture resistance and cut resistance, it has little impact on the softness.

[0062] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several improvements and modifications 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.
