Description

Technical Field

[0001] This invention belongs to the field of textile technology, specifically relating to a roll structure manufacturing device and a shear-thickening gel flexible core-spun yarn manufacturing device. Background Technology

[0002] Impact damage is one of the most common phenomena in structural protection engineering. Due to the prevalence of impact damage, the design of safety protection materials is becoming increasingly important. Shear-thickening gels, with their excellent impact resistance and cushioning properties, are attracting increasing attention in markets such as sports protection, shock absorption, military and police protection, and industrial protection. The hardening mechanism of shear-thickening gels can be attributed to the disordered breakage and recombination of internal BO bonds. Under low strain rate stimulation, the molecular chain motion scale is relatively large, and the BO bonds have sufficient time to break. The damping caused by molecular chain entanglement is the main obstacle to molecular deformation, exhibiting viscous characteristics with fluidity on a macroscopic scale. However, when shear-thickening gels are subjected to high strain rate stimulation, the molecular chains inside the shear-thickening gel do not have enough time for self-adjustment, leading to an order-of-magnitude increase in storage modulus, exhibiting glassy characteristics on a macroscopic scale. Therefore, shear-thickening gels cause the viscosity of the system to increase sharply and instantaneously under high-speed external impact, consuming a large amount of external impact energy. When the external force is removed, the shear-thickening gel material can return to its original soft state, greatly improving the impact resistance, durability, and comfort of protective products.

[0003] Smart protective clothing requires high impact resistance, low weight, flexibility, and integration with multifunctional wearable devices. As a high-performance rate-related material, shear-thickening gel (SSG) has broad scientific value and application prospects in the field of smart impact protection devices. However, current civilian impact-resistant clothing and accessories are typically rigid shell products, restricting human movement and lacking both flexibility and comfort. Flexible polyurethane foam cushioning materials, in particular, have poor thermal and moisture comfort. Aramid impact-resistant protective composite fabrics are relatively stiff, with poor flexibility, softness, and thermal permeability. Compared to traditional protective materials, shear-thickening gel flexible composite materials satisfy the contradiction between protective performance and flexibility and comfort.

[0004] Current techniques typically involve directly immersing protective textiles in a mixture of shear-thickening gel and diluent, then removing the diluent through drying or freeze-drying to obtain a mixture of shear-thickening material and textiles. While this can enhance the impact resistance of textiles to some extent, it suffers from technical drawbacks such as poor abrasion resistance and lack of breathability. Although low-temperature 3D printing technology can be used to mold shear-thickening gel materials, it is currently not feasible to apply them to fabrics.

[0005] Therefore, there is an urgent need to develop a continuous manufacturing method to produce materials that combine superior durability and impact resistance with breathable and soft wearability, enabling the transformation of shear-thickened gel materials into yarns and textiles to meet the needs of military and aerospace industries. Summary of the Invention

[0006] To address the shortcomings of existing technologies, the purpose of this invention is to provide a shear-thickening gel flexible core-spun yarn.

[0007] Another object of the present invention is to provide a method for preparing the above-mentioned shear-thickening gel flexible core-spun yarn.

[0008] Another objective of this invention is to provide the use of the above-mentioned shear-thickening gel flexible core-spun yarn in improving the impact resistance of fabrics. The shear-thickening gel flexible core-spun yarn solves the technical problem that shear-thickening gel cannot be yarn-made for use in impact-resistant protective equipment, and provides a fast and effective method for preparing shear-thickening gel materials into flexible protective clothing.

[0009] Another object of the present invention is to provide the use of the above-mentioned shear-thickening gel flexible core-spun yarn in improving the air permeability of impact-resistant fabrics.

[0010] Another objective of this invention is to provide the aforementioned shear-thickening gel flexible core-spun yarn manufacturing apparatus. This apparatus meets the requirement of continuously preparing shear-thickening gel flexible core-spun yarn into yarn by means of a twisting component to achieve a roll structure; then, a second film and fibers are sequentially wrapped around it to achieve the functionality of the yarn. This shear-thickening gel flexible core-spun yarn manufacturing apparatus automates the production of shear-thickening gel flexible core-spun yarn, improving production efficiency.

[0011] The present invention is achieved through the following technical solution.

[0012] A shear-thickening gel flexible core-spun yarn includes: a core layer, a film layer, and a functional layer, wherein the film layer covers the core layer, and the functional layer covers the film layer. The core layer includes at least one roll structure, which is a Fermat roll structure or an Archimedean roll structure. The functional layer includes fibers. The Fermat roll structure is formed by layered structures wound along a Fermat spiral, and the Archimedean roll structure is formed by layered structures wound along an Archimedean spiral.

[0013] The layered structure includes: a first film and a gel layer covering one side of the first film, the gel layer being a shear-thickening gel, and the first film being made of polytetrafluoroethylene, polyimide, polyetherketone, or polyphenylene sulfide.

[0014] The thin film layer includes a second thin film.

[0015] In the above technical solution, the gel layer accounts for 80-95 wt% of the shear-thickening gel flexible core-spun yarn.

[0016] In the above technical solution, the diameter of the shear-thickening gel flexible core-spun yarn is 2-3 mm.

[0017] In the above technical solution, the thickness of the gel layer is 0.1 to 1.5 mm.

[0018] In the above technical solution, the thickness of the first film is 0.05 to 0.075 mm.

[0019] In the above technical solution, the thickness of the thin film layer is 0.1 to 0.2 mm.

[0020] In the above technical solution, the thickness of the functional layer is 0.1 to 1 mm.

[0021] In the above technical solution, the material of the second film is polyurethane, polyurea or polytetrafluoroethylene.

[0022] In the above technical solution, the thin film layer is formed by wrapping a second thin film, the width of which is 1 to 1.5 cm and the thickness of which is 0.05 to 0.1 mm.

[0023] In the above technical solution, the fiber is one or more of the following: aramid fiber, polyimide fiber, flame-retardant viscose, flame-retardant nylon, flame-retardant polyester, flame-retardant acrylic fiber, and seaweed fiber.

[0024] In the above technical solution, the storage modulus of the shear-thickening gel is 0.51 to 1.13 PMa.

[0025] The method for preparing the above-mentioned shear-thickening gel flexible core-spun yarn includes the following steps: using at least one roll structure as the core layer, wrapping a second film around the core layer as a film layer, and covering the film layer with fibers as a functional layer.

[0026] In the above technical solution, the method for preparing the layered structure includes: uniformly coating a liquid shear-thickening gel onto a first film to obtain a gel layer on the first film, thereby obtaining a layered structure.

[0027] In the above technical solution, the shear-thickening gel is heated to 50-80°C to make it into a liquid state.

[0028] The above-mentioned shear-thickening gel flexible core-spun yarn is used to improve the impact resistance of fabrics.

[0029] The above-mentioned shear-thickening gel flexible core-spun yarn is used to improve the air permeability of impact-resistant fabrics.

[0030] The preparation method of the above-mentioned shear-thickening gel includes the following steps:

[0031] Step 1: Mix pyroboronic acid and PDMS evenly, then add nanoparticles in batches and stir until the nanoparticles are evenly dispersed to obtain a precursor solution. The ratio of pyroboronic acid, PDMS and nanoparticles by mass is 5:(50-100):0.5. PDMS is hydroxyl-terminated polymethylsiloxane. The nanoparticles include: silica particles, polyvinyl chloride particles, calcium carbonate particles, polymethyl methacrylate particles, carbon nanofibers and / or titanium dioxide particles.

[0032] In step 1, the method for obtaining pyroboronic acid includes: keeping boric acid at 120-160°C for 120-240 min to obtain the pyroboronic acid.

[0033] In step 1, the viscosity of PDMS is 50 to 1500 cp.

[0034] Step 2: The precursor solution is heated at 180-220°C for 2-5 hours and then cooled to room temperature to obtain a shear-thickened gel.

[0035] A roll structure manufacturing apparatus includes: a base plate, a groove clamp and a twisting component. N adjusting plates, where N is greater than or equal to 1, are fixedly mounted on one side of the base plate. Each adjusting plate and the base plate form a first channel, and the height inside each first channel gradually decreases from back to front.

[0036] The first film and the gel layer covering one side of the first film are used as a layered structure. The strip-shaped layered structure passes through the first channel of N adjustment plates, the groove clamp and the twisting component in sequence. The groove clamp includes a lower clamp and an upper clamp located directly above the lower clamp. The layered structure passes through the lower clamp and the upper clamp.

[0037] The twisting component includes a first component and a second component, which are arranged opposite to each other. The side of the first component closer to the second component is always the leftward moving surface, and the side of the second component closer to the first component is always the rightward moving surface. The two planes of the first component and the second component that are close to each other are arranged parallel to each other. The twisting component is used to roll the layered structure into a roll structure. The roll structure is a Fermat roll structure or an Archimedean roll structure. The Fermat roll structure is formed by rolling the layered structure along the Fermat spiral, and the Archimedean roll structure is formed by rolling the layered structure along the Archimedean spiral.

[0038] In the above technical solution, the space between the upper clamp and the lower clamp consists of a second channel and gaps located on the left and right sides of the second channel, and the height inside the second channel is higher than that inside the gaps.

[0039] In the above technical solution, the left-moving surface is one side of the conveyor belt, the right-moving surface is one side of the conveyor belt, and the conveyor belt corresponding to the left-moving surface and the conveyor belt corresponding to the right-moving surface may be the same or different.

[0040] In the above technical solution, when N is greater than 1, the N adjustment plates are arranged in a straight line.

[0041] In the above technical solution, when N is greater than 1, the height of the front port of the first channel corresponding to the N adjustment plates gradually decreases from back to front.

[0042] The above technical solution also includes: a container for loading shear-thickening gel, the bottom of the container having a discharge port, the container coating the first film with shear-thickening gel through its discharge port to form a gel layer.

[0043] The above technical solution also includes: a film roll, which is formed by winding a first film, and the first film is discharged from the film roll and passes through the first channels corresponding to N adjustment plates.

[0044] The above technical solution also includes: a transmission device, which includes: a first transmission roller and a grooved roller located above the first transmission roller. The first transmission roller is a mirror roller, and a layered structure passes through the space between the first transmission roller and the grooved roller. A groove is formed on the grooved roller to accommodate the gel layer.

[0045] In the above technical solution, the transmission device is located between the groove clamp and the base plate.

[0046] A shear-thickening gel flexible core-spun yarn manufacturing apparatus includes: M roll structure manufacturing devices, a first bobbin and a second bobbin, where M is greater than or equal to 1. A strip-shaped second film is wound on the first bobbin for winding the second film onto the roll structure obtained by the M roll structure manufacturing devices to form a film layer outside the roll structure. Fibers are wound on the second bobbin for winding fibers around the film layer to form a functional layer.

[0047] In the above technical solution, the shear-thickening gel flexible core-spun yarn manufacturing device further includes a cooling device, which is located between the roll structure manufacturing device and the first bobbin.

[0048] The beneficial effects of this invention are:

[0049] 1. This invention breaks through the technical bottleneck that shear-thickening gels cannot be yarn-formed, and realizes a simple yarn-forming process for shear-thickening gels, providing a new way for industrial manufacturing of continuous, comfortable, durable, impact-resistant protective yarns and fabrics.

[0050] 2. The thickness of the flexible core-spun yarn made of shear-thickening gel in this invention is adjustable, and it has soft, breathable, durable, leak-proof, and impact-resistant properties. The shear-thickening gel has excellent impact resistance, the film layer has good sealing and bonding strength, and the functional layer exhibits interception and barrier impact resistance. The multi-layered structure works synergistically to demonstrate excellent impact protection capabilities, making it applicable to human clothing protection.

[0051] 3. The shear-thickening gel flexible core-spun yarn of this invention is easy to spin and form, realizing the built-in short-process yarn forming of shear gel material. The yarn is a unique core-sheath composite yarn, thus solving the technical limitations of the prior art in which shear-thickening gel is directly impregnated or coated on the fabric surface, resulting in such impact-resistant fabrics being relatively hard, neither flexible nor comfortable, restricting human movement, and affecting the thermal and moisture comfort of the fabric when worn.

[0052] 4. In order to automate the production of shear-thickening gel flexible core-spun yarn, this invention also provides a shear-thickening gel flexible core-spun yarn manufacturing device. This device realizes a simplified yarn-forming process for shear-thickening gel, and avoids the time-consuming problem of traditional manual operation through automated processes such as coating, curling, and wrapping.

[0053] 5. The shear-thickening gel flexible core-spun yarn equipment of the present invention can accurately control the content and distribution of shear-thickening gel in films and yarns, avoid gel delamination or aggregation, ensure long-term stability, and improve protective performance.

Detailed Implementation

[0068] The following detailed description, with reference to the accompanying drawings, illustrates the shear-thickening gel flexible core-spun yarn of the present invention, its preparation method, and its applications.

[0069] Examples 1-4

[0070] A method for preparing a shear-thickening gel includes the following steps:

[0071] Step 1: Boric acid is kept at 160℃ for 90 min to obtain pyroboric acid. Pyroboric acid and PDMS are mixed evenly, and then nanoparticles are added in batches. The mixture is stirred until the nanoparticles are evenly dispersed to obtain a precursor solution. The ratio of pyroboric acid, PDMS and nanoparticles by mass is Y. PDMS is hydroxyl-terminated polymethylsiloxane (purchased from Wenzhou Shoucheng Chemical Technology Co., Ltd.), nanoparticles are silica particles, and the viscosity of PDMS is X cp.

[0072] Step 2: The precursor solution is heated at 220°C for 2.5 hours and then cooled to room temperature (20-25°C) to obtain a shear-thickened gel.

[0073] The storage modulus, X, and Y of the shear-thickened gel are shown in Table 1.

[0076] Example 5

[0077] like Figure 1 As shown, a shear-thickening gel flexible core-spun yarn includes: a core layer S11, a thin film layer S12, and a functional layer S13. The thin film layer covers the core layer, and the functional layer covers the thin film layer. The thickness of the thin film layer is 0.2 mm, and the thickness of the functional layer is 1 mm. The core layer is a roll structure, which is an Archimedean roll structure. The Archimedean roll structure is formed by rolling layered structures along an Archimedean spiral, as shown. Figure 3 As shown. The layered structure consists of a first film and a gel layer covering one side of the first film. The gel layer is the shear-thickening gel in Example 2. The thickness of the gel layer is 1 mm. The material of the first film is polytetrafluoroethylene. The thickness of the first film is 0.075 mm. The width of the first film is 10 mm (the areal density of the first film is 50 g / km).

[0078] The method for preparing the above-mentioned shear-thickening gel flexible core-spun yarn includes the following steps:

[0079] S1, The shear thickening gel in Example 2 is heated at 80°C for 1 hour to make it liquid, thereby improving the fluidity of the shear thickening gel and enabling it to be applied to the first film efficiently, conveniently and uniformly; the liquid shear thickening gel is uniformly coated on the first film to obtain a gel layer and a layered structure; the layered structure is rolled along the Archimedean spiral into an Archimedean coil structure as the core layer;

[0080] S2, a second film is wrapped around the core layer as a film layer. The material of the second film is polytetrafluoroethylene, the width of the second film is 1 cm, and the thickness of the second film is 0.075 mm (the linear density of the second film is 50 g / km).

[0081] A fiber is coated onto the outside of the film layer as a functional layer. The fiber is flame-retardant polyester.

[0082] The gel layer accounts for 80 wt% of the shear-thickening gel flexible core-spun yarn, and the diameter of the shear-thickening gel flexible core-spun yarn is 2.5 mm.

[0083] Example 6

[0084] A plain weave fabric (No.: A) is obtained by machine weaving, with a warp density of 3 yarns / cm, a weft density of 2 yarns / cm, and a thickness of about 3mm. Both the warp and weft yarns of the plain weave fabric are made of the shear-thickening gel flexible core-spun yarn of Example 5.

[0085] Comparative Example 1

[0086] A plain weave fabric (No. B) is obtained by machine weaving, with a warp density of 3 yarns / cm, a weft density of 2 yarns / cm, and a thickness of approximately 3mm. Both the warp and weft yarns of the plain weave fabric are made of wool (2.5mm in diameter).

[0087] Dynamic impact tests were conducted on the plain weave fabrics prepared in Example 6 and Comparative Example 1 to obtain the load-time curves of the plain weave fabrics at an impact height of 50 mm, as shown below. Figure 5 As shown, A represents the plain weave fabric in Example 6, and B represents the plain weave fabric in Comparative Example 1. Figure 5 It is known that plain weave fabric has the highest peak load, which is not conducive to absorbing impact energy. Compared with plain weave fabric obtained from wool yarn, plain weave fabric obtained from shear-thickened gel flexible core-spun yarn effectively reduces the peak load of 783N. Moreover, when the load peak is reached, the plain weave fabric of Example 6 takes 1.5ms longer than the plain weave fabric of Comparative Example 1. These fully demonstrate that the plain weave fabric obtained from shear-thickened gel flexible core-spun yarn has better impact energy absorption capacity.

[0088] Planar compression tests were conducted on the plain weave fabrics prepared in Example 6 and Comparative Example 1. The plain weave fabrics were placed between two parallel compression plates, and a pressure perpendicular to the plane of the plain weave fabric was applied to the compression plates using a testing machine, causing the plain weave fabric to undergo uniform compression. During the compression process, the testing machine recorded the applied pressure value and the corresponding compression deformation of the plain weave fabric, thereby obtaining the compression performance curve (stress-strain curve) of the plain weave fabric, as shown below. Figure 6 As shown, A represents the plain weave fabric in Example 6, and B represents the plain weave fabric in Comparative Example 1. Figure 6 It can be seen that both curves show a trend of slow initial increase followed by rapid increase in stress with increasing strain. When the strain is small (approximately 0-20%), the stress increase is relatively gradual; when the strain exceeds a certain level (approximately 40%), the stress increases sharply, and the strain rate reaches 50%. The strain of the plain weave fabric obtained from the shear-thickened gel flexible core-spun yarn is 2.5 times that of the plain weave fabric obtained from the wool yarn. The stress value of the plain weave fabric obtained in Example 1 is generally higher than that of the plain weave fabric in Comparative Example 1, indicating that the plain weave fabric obtained from the shear-thickened gel flexible core-spun yarn has higher strength, can withstand greater external forces without damage, and has better resistance to deformation. This fully demonstrates that the shear-thickened gel flexible core-spun yarn has better impact resistance and strength.

[0089] The plain weave fabric prepared in Example 6 has large pores and good air permeability. This plain weave fabric can be folded, bent, stretched, etc., and has good softness. It is durable and leak-proof. The plain weave fabric did not show any shear thickening gel leakage problem after 6 months.

[0090] Example 7

[0091] A plain weave fabric, essentially the same as in Example 6, except that the core layer is one such... Figure 2 The Fermat roll structure is shown.

[0092] The plain weave fabric of Example 7 can achieve the same technical effects as that of Example 6.

[0093] The shear-thickening gels obtained in Examples 1, 3 and 4 can achieve the same technical effects as the shear-thickening gel obtained in Example 2.

[0094] A patent has been filed for a shear-thickening gel flexible core-spun yarn material, application number 2025103434439.

[0095] Example 8

[0096] In Example 5, the shear-thickening gel flexible core-spun yarn can be manufactured manually or mechanically. To mechanize the preparation of the shear-thickening gel flexible core-spun yarn in Example 5, this example designs a shear-thickening gel flexible core-spun yarn manufacturing device, such as... Figures 7-12 As shown, the shear-thickening gel flexible core-spun yarn manufacturing device includes: M roll structure manufacturing devices (M=1), cooling device 10, first bobbin 11 and second bobbin 12;

[0097] The roll structure manufacturing apparatus includes: a film roll 1, a container 2 for loading liquid shear-thickening gel, a transmission device, a base plate 4, a groove clamp 8, and a twisting component 9. The film roll 1 is formed by winding a first film 3-1 and is used to provide the first film 3-1.

[0098] The bottom of container 2 has a discharge port, through which container 2 coats the first film 3-1 provided by film roll 1 with shear thickening gel to form a gel layer. Container 2 can extrude the shear thickening gel in a metered manner, coating it in a linear pattern on the first film 3-1.

[0099] N adjusting plates 5, where N=4, are fixedly mounted on one side of the base plate 4. The N adjusting plates 5 are arranged in a straight line. Each adjusting plate 5 and the base plate 4 form a first channel 5-1, as shown below. Figure 9 and Figure 10 As shown, the height inside each first channel 5-1 gradually decreases from back to front (with the forward direction of the first film as "front"); the height of the front port of the first channel 5-1 corresponding to the N adjustment plates 5 gradually decreases from back to front.

[0100] The first film 3-1 exits from the film roll 1 and passes through the first channels 5-1 corresponding to the N adjusting plates 5. The container 2 coats the first film 3-1 with shear thickening gel to form a gel layer. The first film 3-1 and the gel layer 3-2 covering one side of the first film 3-1 are used as a layered structure 3. The strip-shaped layered structure 3 passes through the first channels 5-1 of the N adjusting plates 5, the transmission device, the groove clamp 8, and the twisting component 9 in sequence. By passing through the first channels 5-1, the coating height of the shear thickening gel on the first film 3-1 can be reduced from back to front, ensuring that the shear thickening gel is uniformly coated on the first film.

[0101] The transmission device includes a first transmission roller 6 and a grooved roller 7 located above the first transmission roller 6. The first transmission roller 6 is a mirror roller. The layered structure 3 passes through the space between the first transmission roller 6 and the grooved roller 7. A groove is formed on the grooved roller 7 to accommodate the gel layer 3-2. The width of the groove is smaller than the width of the first film and larger than the width of the gel layer. The transmission device plays a transmission role.

[0102] The grooved clamp 8 includes a lower clamp 8-2 and an upper clamp 8-1 located directly above the lower clamp 8-2. A layered structure 3 passes between the lower clamp 8-2 and the upper clamp 8-1. The space between the upper clamp 8-1 and the lower clamp 8-2 consists of a second channel and gaps located on the left and right sides of the second channel. The height of the second channel is higher than the gaps. The second channel is used to pass through the gel layer and the first film directly below it, while the gaps are used to pass through the first films on the left and right sides of the gel layer. The grooved clamp 8 is used to fix the surface of the first film.

[0103] like Figure 12 As shown, the twisting component 9 includes: a first component 9-1 and a second component 9-2, which are arranged opposite to each other. The side of the first component 9-1 closest to the second component 9-2 is always the left-moving surface, and the side of the second component 9-2 closest to the first component 9-1 is always the right-moving surface. The two planes of the first component 9-1 and the second component 9-2, which are close to each other, are arranged parallel to each other. The twisting component 9 (between the left-moving surface and the right-moving surface) is used to roll the layered structure 3 into a roll structure. The roll structure is a Fermat roll structure or an Archimedean roll structure. The Fermat roll structure is formed by rolling the layered structure 3 along a Fermat spiral, and the Archimedean roll structure is formed by rolling the layered structure 3 along an Archimedean spiral. In this embodiment, the left-moving surface is one side of the conveyor belt, and the right-moving surface is another side of the conveyor belt. The conveyor belts corresponding to the left-moving surface and the conveyor belts corresponding to the right-moving surface are different. Figure 12 As shown, the first component and the second component each consist of a conveyor belt.

[0104] A strip-shaped second film is wound around the first bobbin 11 to form a film layer on the outside of the roll structure; the cooling device 10 is located between the roll structure manufacturing device and the first bobbin 11 to cool the roll structure (to 0-5℃) so that the shear thickening gel becomes a soft, solid material, thereby reducing the fluidity of the shear thickening gel in the roll structure and preventing leakage or significant deformation of the shear thickening gel material.

[0105] The second bobbin 12 is wound with fibers to form a functional layer around the film layer. The feeding component 13 is used to uniformly and stably transport the yarn to the next area. The outer winding assembly 14 is used to wind the yarn into a specific shape according to certain rules, facilitating storage, transportation, and post-processing (the outer winding assembly 14 can be, for example, a yarn guide, tension device, winding roller, or yarn clearer). After winding the fibers, shear-thickened gel flexible core-spun yarn is obtained, which can be wound up through a third bobbin.

[0106] The working process of the above-mentioned shear-thickening gel flexible core-spun yarn manufacturing device is as follows:

[0107] 1) Install the first film: Pull the first film out from the film roll 1 and let it pass through the first channel 5-1 corresponding to the N adjustment plates 5 in sequence, then pass between the first drive roller 6 and the groove roller 7, and further pass between the lower clamp 8-2 and the upper clamp 8-1. If the roll structure to be formed is a Fermat roll structure, fold the first film in the left and right direction and put it between the left moving surface and the right moving surface of the twisting component; if the roll structure to be formed is an Archimedes roll structure, put the first film directly between the left moving surface and the right moving surface of the twisting component.

[0108] The first film is pulled out from the twisting component, passes through the cooling device, is pulled out from the cooling device, and is connected to the third cylinder.
