Description

Technical Field

[0001] The invention belongs to the technical field of textiles, and in particular relates to a roll structure manufacturing device and a shear thickening gel flexible core-spun yarn manufacturing device. Background Art

[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. Due to their excellent impact resistance and cushioning properties, shear-thickening gels are gaining 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 rates, the molecular chains move relatively large, giving the BO bonds ample time to break. The damping caused by molecular chain entanglement is the primary obstacle to molecular deformation, resulting in a fluid, viscous structure on a macroscopic scale. However, when shear-thickening gels are subjected to high strain rates, the molecular chains within the gels lack sufficient time to self-align, resulting in an order-of-magnitude increase in the storage modulus and a glassy appearance on a macroscopic scale. Consequently, shear-thickening gels cause a dramatic increase in viscosity when subjected to high-speed impact, dissipating a significant amount of the impact energy. Once the force is removed, the shear-thickening gel material returns to its original soft state, significantly 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 efficiency-related material, shear thickening gel (SSG) has broad scientific value and application prospects in the field of smart anti-collision devices. However, current civilian impact-resistant clothing and accessories are usually hard shell products, which restrict human movement and are neither flexible nor comfortable. In particular, flexible polyurethane foam cushioning materials have poor thermal and moisture comfort. Aramid impact-resistant protective composite fabrics have relatively hard finished fabrics, and their flexibility, softness, and thermal and moisture permeability are poor. Compared with traditional protective materials, shear thickening gel flexible composite materials meet the contradiction between protective performance and flexibility and comfort.

[0004] Current technology typically involves directly immersing protective textiles in a mixture of shear-thickening gel and a diluent solvent, then removing the diluent through drying or freeze-drying to create a shear-thickening material-textile mixture. While this can enhance the textile's impact resistance to a certain extent, it suffers from technical drawbacks such as poor wear resistance and air permeability. While low-temperature 3D printing has been used to mold shear-thickening gel materials, its application to fabrics is currently unattainable.

[0005] Therefore, there is an urgent need to develop a continuous manufacturing method for manufacturing materials that have both super-strong and long-lasting impact resistance and moisture permeability / breathability / soft wearing comfort, and to realize the transformation of shear thickening gel materials into yarns and fabric textile materials to serve the needs of military and aerospace industries.

DETAILED DESCRIPTION

[0068] The shear thickening gel flexible core-spun yarn of the present invention and its preparation method and application are described in detail below with reference to the accompanying drawings.

[0069] Examples 1 to 4

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

[0072] Step 2: continuously heating the precursor solution at 220° C. for 2.5 hours and cooling it to room temperature (20-25° C.) to obtain a shear thickening gel.

[0073] The storage modulus, X, and Y of the shear thickening 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 film layer S12 and a functional layer S13, the film layer is coated on the outside of the core layer, the functional layer is coated on the outside of the film layer, the thickness of the film layer is 0.2 mm, the thickness of the functional layer is 1 mm, the core layer is a roll structure, the roll structure is an Archimedean roll structure, and the Archimedean roll structure is formed by a layered structure rolled along an Archimedean spiral, as shown in FIG. Figure 3 The layered structure comprises a first film and a gel layer covering one side of the first film. The gel layer is the shear thickening gel of Example 2. The gel layer has a thickness of 1 mm. The first film is made of polytetrafluoroethylene, has a thickness of 0.075 mm, and a width of 10 mm (the surface density of the first film is 50 g / km).

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

[0079] S1, heating the shear thickening gel in Example 2 at 80° C. for 1 hour to convert it into a liquid state, thereby improving the fluidity of the shear thickening gel and enabling it to be efficiently, conveniently and evenly coated on the first film; uniformly coating the liquid shear thickening gel on the first film to form a gel layer on the first film to form a layered structure; and rolling the layered structure along an Archimedean spiral into an Archimedean roll structure as a core layer;

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

[0081] The film layer is covered with fibers as a functional layer. The fibers are 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 fabric (number: A) is obtained by weaving, with a warp density of 3 yarns / cm and a weft density of 2 yarns / cm. The plain fabric thickness is about 3 mm. Both the warp and weft yarns of the plain fabric are made of the shear thickening gel flexible core-spun yarn of Example 5.

[0085] Comparative Example 1

[0086] A plain weave fabric (number: B) is obtained by weaving, has a warp density of 3 yarns / cm, a weft density of 2 yarns / cm, and a thickness of about 3 mm. Both the warp and weft yarns of the plain weave fabric are wool yarns (the yarn diameter is 2.5 mm).

[0087] The plain fabrics prepared in Example 6 and Comparative Example 1 were subjected to a dynamic impact test to obtain a load-time curve of the plain fabric at an impact height of 50 mm. Figure 5 As shown, wherein A represents the plain weave fabric in Example 6, and B represents the plain weave fabric in Comparative Example 1. Figure 5 It can be seen that the plain fabric has the highest peak load, which is not conducive to absorbing impact energy. Compared with the plain fabric obtained from wool, the plain fabric obtained from the shear thickening gel flexible core-spun yarn effectively reduces the peak load of 783N, and when reaching the load peak, the plain fabric of Example 6 takes 1.5ms longer than the plain fabric of Comparative Example 1. These fully demonstrate that the plain fabric obtained from the shear thickening gel flexible core-spun yarn has better impact energy absorption capacity.

[0088] The plain fabrics prepared in Example 6 and Comparative Example 1 were subjected to a plane compression test. The plain fabrics were placed between two parallel compression plates. A testing machine applied pressure perpendicular to the plane of the plain fabric to uniformly compress the plain fabric. During the compression process, the testing machine recorded the applied pressure and the corresponding compression deformation of the plain fabric, thereby obtaining a compression performance curve (stress-strain curve) of the plain fabric, as shown in Figure 1. Figure 6 As shown, wherein 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 with the increase of strain, the stress of both curves shows a trend of first slowly rising and then rapidly rising. When the strain is small (about 0-20% range), the stress increases relatively slowly; when the strain exceeds a certain level (after about 40%), the stress rises sharply, and the strain rate is 50%. The strain of the plain fabric obtained by shear thickening gel flexible core-spun yarn is 2.5 times that of the plain fabric obtained by wool. The stress value of the plain fabric obtained in Example 1 is generally higher than that of the plain fabric in Comparative Example 1, indicating that the plain fabric obtained by shear thickening gel flexible core-spun yarn has higher strength, can withstand greater external forces without damage, and has better deformation resistance. It fully demonstrates that the shear thickening gel flexible core-spun yarn has better impact resistance and strength.

[0089] The plain fabric prepared in Example 6 has larger pores and better air permeability. The plain fabric can be folded, bent, stretched, etc. and has good softness. It is leak-proof and has no shear thickening gel leakage problem after 6 months.

[0090] Example 7

[0091] A plain weave fabric, which is substantially the same as that of Example 6, except that the core layer is a Figure 2 The Fermat roll structure shown.

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

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

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

[0095] Example 8

[0096] The shear thickening gel flexible core-spun yarn in Example 5 can be manufactured by hand or by machine. In order to mechanizedly prepare the shear thickening gel flexible core-spun yarn in Example 5, this embodiment designs a shear thickening gel flexible core-spun yarn manufacturing device, such as Figures 7 to 12 As shown, the shear thickening gel flexible core-spun yarn manufacturing device includes: M roll structure manufacturing devices (M=1), a cooling device 10, a first bobbin 11 and a second bobbin 12;

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

[0098] The container 2 has a discharge port formed at the bottom thereof, through which the container 2 applies the shear thickening gel to form a gel layer on the first film 3-1 provided by the film roll 1. The container 2 can extrude the shear thickening gel in a quantitative manner and apply it in a linear pattern on the first film 3-1.

[0099] N adjusting plates 5 are fixedly mounted on one side of the bottom plate 4, where N=4. The N adjusting plates 5 are arranged in a straight line. A first channel 5-1 is formed between each adjusting plate 5 and the bottom plate 4. 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 ports of the first channels 5-1 corresponding to the N adjustment plates 5 gradually decreases from back to front.

[0100] A first film 3-1 is discharged from a film roll 1 and passes through the first channels 5-1 corresponding to the N adjustment plates 5. A container 2 coats the first film 3-1 with a 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 form a layered structure 3. The strip-shaped layered structure 3 sequentially passes through the first channels 5-1 of the N adjustment plates 5, a transmission device, a groove fixture 8, and a twisting component 9. The passage through the first channels 5-1 allows the coating height of the shear thickening gel on the first film 3-1 to decrease from back to front, ensuring a uniform coating of the shear thickening gel 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 between the first transmission roller 6 and the grooved roller 7. A circle of recessed grooves for accommodating the gel layer 3-2 is formed on the grooved roller 7. The width of the recessed 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 groove fixture 8 comprises a lower fixture 8-2 and an upper fixture 8-1 positioned directly above the lower fixture 8-2. The layered structure 3 passes between the lower fixture 8-2 and the upper fixture 8-1. The space between the upper fixture 8-1 and the lower fixture 8-2 consists of a second channel and slits on either side of the second channel. The second channel is higher than the slits. The second channel is designed to pass through the gel layer and the first film directly below it, while the slits are designed to pass through the first film on either side of the gel layer. The groove fixture 8 is used to secure 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, the first component 9-1 and the second component 9-2 are arranged opposite to each other, the side of the first component 9-1 close to the second component 9-2 is always the left moving surface, and the side of the second component 9-2 close 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 close to each other are arranged in parallel, and 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, and the roll structure is a Fermat roll structure or an Archimedean roll structure. The Fermat roll structure is formed by the layered structure 3 being rolled along the Fermat spiral, and the Archimedean roll structure is formed by the layered structure 3 being rolled along the Archimedean spiral. In this embodiment, the left moving surface is a surface of the conveyor belt, and the right moving surface is a surface of the conveyor belt. The conveyor belt corresponding to the left moving surface and the conveyor belt corresponding to the right moving surface are different. As shown Figure 12 As shown, the first component and the second component are each a conveyor belt.

[0104] A strip-shaped second film is wound on the first tube 11, which is used to wrap the second film on the roll structure to form a film layer outside the roll structure; the cooling device 10 is located between the roll structure manufacturing device and the first tube 11, and is used to cool the roll structure (to 0-5°C) to make the shear thickening gel into a soft mud solid material, so as to reduce the fluidity of the shear thickening gel in the roll structure and prevent the shear thickening gel material from leaking or obviously deforming.

[0105] The second bobbin 12 is wound with fibers and used to wrap the fibers around the film layer to form the functional layer. A feed assembly 13 ensures uniform and stable yarn delivery to the next area. The outer wrapping assembly 14 is used to wind the yarn into a specific package shape according to a specific pattern, facilitating storage, transportation, and post-processing. (External wrapping assembly 14 may include, for example, a yarn guide, tensioning device, winding rollers, and a yarn clearer.) After winding the fibers, the resulting shear-thickening gel-coated flexible core-spun yarn is rewound onto 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) Installing the first film: Pull the first film from the film roll 1 and pass it through the first channels 5-1 corresponding to the N adjustment plates 5 in sequence, then pass it between the first transmission roller 6 and the groove roller 7, and further pass it between the lower clamp 8-2 and the upper clamp 8-1. If the roll structure to be formed is a Fermat roll structure, the first film is folded in half in the left-right direction and placed between the leftward and rightward moving surfaces of the twisting component; if the roll structure to be formed is an Archimedean roll structure, the first film is directly placed between the leftward and rightward moving surfaces of the twisting component;

[0108] The first film is pulled out from the twisting component and passed through the temperature reduction device, and the first film is pulled out from the temperature reduction device and connected to the third bobbin.

[0109] 2) The third bobbin is wound up and the container is coated with the shear thickening gel on the first film.

[0110] Example 9

[0111] A shear thickening gel flexible core-spun yarn manufacturing device is basically the same as that of Example 8, the only difference being that: M = 2. Figure 13 The shear thickening gel flexible core-spun yarn manufacturing device can automatically prepare a shear thickening gel flexible core-spun yarn with a core layer of two rolls.

[0112] The above is an exemplary description of the present invention.
