Description

Technical Field

[0001] The present application relates to the technical field of textile materials, and in particular to a horizontally knitted flaky anti-stab structure fabric and a preparation method thereof. Background Art

[0002] At present, with the growing demand for security protection, stab-proof materials are increasingly used in the fields of military, police, personal protection, etc. Stab-proof materials need to be lightweight, high-strength, soft and comfortable in order to provide effective protection in various harsh environments.

[0003] Stab-proof materials are usually of three types: hard, semi-hard and soft. Hard stab-proof materials are usually made of metal armor plates and hard composite materials as stab-proof armor plates, which are relatively bulky. Soft stab-proof materials are mostly made of fabrics with high-performance fibers such as ultra-high molecular weight polyethylene and aramid for laminated composite processing, and their protective performance is limited. Therefore, it is of great significance to develop stab-proof materials with excellent protective performance, light weight and flexibility.

[0005] Patent CN113152107A discloses a method for preparing a nanocomposite gel matrix multilayer fabric stab-proof composite material, which comprises stirring and mixing chemical reagents, adjusting the temperature to 0-10°C, adding monomers, initiators and promoters, and introducing nitrogen for at least 15 minutes for nitrogen bubbling to obtain a nanocomposite hydrogel, stacking multiple layers of aramid fabric impregnated with the nanocomposite hydrogel, and standing in a vacuum environment for at least 24 hours to obtain a nanocomposite gel matrix multilayer fabric stab-proof composite material. However, the preparation process is extremely complicated, and the cost is high, the product is relatively thick, and the stab-proof performance is poor.

[0006] Patent CN108859319A discloses a puncture-proof composite fabric structure that is soft, light and has strong puncture resistance. The structure consists of a skin-friendly layer, a surface layer, a steel wire braided layer and a puncture-proof layer. The puncture-proof layer consists of a plurality of evenly distributed hard protective blocks, which are connected and attached to the steel wire braided layer by high-strength metal fiber wires or rivets to form a puncture-proof composite fabric structure. However, although the flexibility of the structure has been improved to a certain extent, the steel wire braiding method increases the difficulty of weaving and the discomfort of the clothing.

[0007] Patent CN118257050A discloses a knitted multi-layer hollow heterogeneous protective structure fabric, which can be filled with stab-proof blocks of different materials. However, since the stab-proof blocks are difficult to fix during human activities, after the stab-proof blocks are inserted into the knitted structure, they are easy to fall off when squeezed.

[0056] Figure 3 A schematic diagram of the coil structure of the horizontally knitted scaly anti-stab structural fabric containing the anti-stab block provided in an embodiment of the present application is shown after the anti-stab block is inserted.

[0057] In detail, the horizontally knitted flaky stab-proof structural fabric is a hollow stab-proof structure that is regularly arranged and overlapped. The smallest circulating organizational unit of the hollow stab-proof structure (i.e., a stab-proof structural unit) includes: a surface layer 1, a bottom layer 3, and an intermediate layer 2 located between the surface layer and the bottom layer; a plurality of bag-shaped hollow interlayers 4 connected on three sides and opened on one side are formed between the surface layer 1 and the intermediate layer 2, and between the bottom layer 3 and the intermediate layer 2 by a needle turning action, and a plurality of bag-shaped hollow interlayers 4 overlap with each other to form the skeleton of the fabric, and a stab-proof block 5 is replaceably arranged in the bag-shaped hollow interlayer; wherein the surface layer 1 has an extension portion 11, and the extension portion 11 is located in a direction close to one side of the opening of the bag-shaped hollow interlayer 4, and the extension portion is locked by introducing an elastic thread to prevent curling and ensure the flatness of the fabric surface.

[0058] In some possible embodiments, the flat-knitted flaky anti-stab structure fabric is knitted once by a four-needle bed fully formed computerized flat knitting machine, and is flat-pressed to form a regularly arranged and overlapping hollow anti-stab structure.

[0059] In some possible embodiments, the surface layer, the bottom layer, and the middle layer have different knitting structures. Affected by the knitting structure, the surface layer, the middle layer, and the bottom layer of the fabric have different densities. Since the surface layer has a high density and the middle layer and the bottom layer have low densities, the longitudinal length of the surface layer is greater than that of the middle layer and the bottom layer. In addition, the surface layer contains an extension of the fabric surface layer, so as to better wrap the stab-proof block.

[0060] In some possible embodiments, the stab-proof block is a hard stab-proof block, which includes at least one of resin, alloy, and metal armor plate.

Figure 4 (b) is the minimum cycle of the main part of the first stab-resistant structural unit, Figure 4 (c) is a weaving process diagram of the connection of the stab-proof structural unit, Figure 4 (d) is a weaving process diagram of the surface extension portion of the stab-proof structural unit, Figure 4 (e) is the minimum cycle of the main part of the second stab-resistant structural unit, Figure 4 (f) is the weaving process diagram at the end.

[0062] Specifically, the preparation method of the horizontally knitted flaky stab-proof structural fabric is used to weave the horizontally knitted flaky stab-proof structural fabric as described above. The method uses 600D ultra-high molecular weight polyethylene yarn to prepare the horizontally knitted flaky stab-proof structural fabric on a Shima Seiki four-needle bed fully formed computerized flat knitting machine, and the type of yarn can be changed according to actual working conditions, such as selecting comfortable and friendly fibers for the bottom layer and selecting high-strength and high-modulus yarns for the surface layer, etc., to meet actual production needs.

[0066] S2, body knitting: the coils of the front lower and rear lower needle beds are transferred to the rear upper and front upper auxiliary needle beds respectively, and the looping method of the coils is controlled to complete the knitting of the multi-layer structure. Among them, the surface layer mainly uses the front lower and rear upper auxiliary needle beds to knit 2+2 rib structure, and the middle layer and bottom layer mainly use the rear lower and front upper auxiliary needle beds to knit 1-in-1 structure.

[0067] It is worth mentioning that at the position where the bag-shaped hollow interlayer formed by the surface layer and the middle layer of each stab-proof structural unit intersects on the left and right, the coils of the surface layer at the connection are located below the coils of the middle layer by changing the local weaving, so as to realize the front-to-back connection between the surface layer and the middle layer; at the position where the bag-shaped hollow interlayer formed by the middle layer and the bottom layer of each stab-proof structural unit intersects on the left and right, the coils of the middle layer at the connection are located below the coils of the bottom layer by using the needle turning process and controlling the loop forming method of the rear needle bed.

[0080] In this embodiment, the stab-proof block set in the bag-shaped hollow interlayer is a carbon fiber hard resin plate. Its knitted coils will tightly wrap the stab-proof block, and the extension of the knitted surface can prevent the stab-proof block from sliding or falling off. At the same time, the stab-proof block is not fixed and can be disassembled and replaced if damaged, which is very suitable for some daily jobs that may cause stab injuries. In addition, this method is one-time molding, the back-end process is simple, and the production efficiency can be improved. It also has the properties of softness, flexibility, and processability.

[0081] The above is only a preferred implementation of the present application.
