Description

Technical Field

[0001] This utility model relates to the field of textile technology, and in particular to a three-proof and easy-to-clean knitted fabric. Background Technology

[0002] Traditional knitted fabrics generally suffer from problems such as limited functionality, insufficient protection, and a conflict between comfort when facing complex usage scenarios, making it difficult to meet the comprehensive demands of modern applications for stain resistance, water resistance, abrasion resistance, and lightweight properties. Specifically, existing technologies face the following technical bottlenecks:

[0003] (1) Conventional knitted fabrics mostly adopt a flat structure and lack three-dimensional flow design, which causes rainwater, sweat and other liquids to spread or linger on the surface, which can easily cause penetration, adhesion or bacterial growth, affecting the wearing experience and hygiene; although some fabrics achieve waterproofing through coating, they sacrifice breathability and exacerbate the stuffiness; (2) Stain and water resistance usually rely on chemical coatings or high-density weaving, but the coating is easy to wear off, and the dense structure will cause the fabric to be stiff, increase the coefficient of friction and reduce wear resistance; (3) In order to achieve lightweight characteristics, existing fabrics often reduce weight by reducing the number of yarns or layers, but this will lead to a decrease in mechanical properties (such as poor tear resistance) and cannot meet the strength requirements of outdoor, sports and other scenarios.

[0004] Chinese Patent Publication No. CN222742335U discloses a stain-resistant polyester fabric, comprising: a stain-resistant layer, an antibacterial layer, a light-blocking layer, and a formaldehyde-removing layer sequentially laminated together; the stain-resistant layer is woven from antistatic yarn as warp and celecox biodegradable fiber yarn as weft; the surfaces of the antistatic yarn and celecox biodegradable fiber yarn are coated with a three-proof finishing agent; the light-blocking layer is woven from black, fully matte polyester filaments; the formaldehyde-removing layer is woven from polyester network yarn as warp and photocatalytic fiber yarn as weft. The stain-resistant layer, antibacterial layer, light-blocking layer, and formaldehyde-removing layer are laminated together by a mesh hot melt adhesive. The stain-resistant and waterproof functions of this fabric rely on a chemical coating, which is easily worn off; furthermore, the lamination of the stain-resistant layer, antibacterial layer, light-blocking layer, and formaldehyde-removing layer with a mesh hot melt adhesive means that the fabric layers easily separate after the adhesive layer peels off, affecting the three-proof performance.

[0005] Chinese Patent Publication No. CN222908214U discloses a three-proof fleece-like fabric, including a fabric structure. The horizontal braiding includes hemp fibers and a coating agent A applied to the outer surface of the hemp fibers, while the vertical braiding includes bamboo fibers and a coating agent B applied to the outer surface of the bamboo fibers. This invention soaks bamboo and hemp fibers in the coating agents. Coating agents A and B respectively alter the surface tension of the bamboo and hemp fibers, preventing moisture penetration and avoiding mold growth caused by water absorption. Polyamide fibers have high abrasion resistance, and polyester fibers have good tensile strength and abrasion resistance, facilitating the maintenance of a clean appearance. Polytetrafluoroethylene (PTFE) films A and B allow air to pass through, maintaining the fabric's breathability. The inclusion of polyamide and polyester fibers increases the fabric's wind resistance. The composite coating waterproofs the horizontal and vertical braiding lines, giving the fabric the advantages of being three-proof. However, this fabric has a flat structure; although waterproofing is achieved through the coating, breathability is sacrificed. Furthermore, the coating is prone to peeling off after several washes, resulting in decreased waterproof, stain-resistant, and oil-resistant properties. Utility Model Content

[0006] Therefore, in view of the above problems, this utility model provides a three-proof and easy-to-clean knitted fabric, which solves the problem that existing knitted fabrics cannot simultaneously achieve liquid penetration barrier on the outer layer, dense protection on the inner layer, good wear resistance and overall lightweight fabric.

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

[0008] A three-proof and easy-to-clean knitted fabric includes a fabric body, which includes a surface layer, a support layer, and a bottom layer. The support layer is located between the surface layer and the bottom layer, and a three-dimensional flow channel is provided between the surface layer and the bottom layer. The fabric body is woven by at least five combs through a warp knitting process.

[0009] The GB2 comb uses a warp-pile weave with a weave structure of 1-0-1-1 / 2-3-2-2 / / full weave, forming a dense pile structure on the surface of the fabric;

[0010] The GB3 comb uses a plain weave with a weave structure of 1-0 / 1-2 / / full penetration, forming an intermediate support layer;

[0011] The comb JB4.1 adopts a missing pad structure, with a structure of 1-0-2-3 / 1-2-0-1 / / 1 through 1 open, forming a three-dimensional groove structure;

[0012] Comb JB4.2 and JB4.1 are symmetrically arranged. Comb JB4.2 adopts a missing pad structure with a structure of 2-3-1-0 / 0-1-2-3 / / 1 through 1 open, which together with JB4.1 forms a three-dimensional flow channel.

[0013] The GB5 comb uses a warp-satin weave with a structure of 3-4 / 2-1 / 1-0 / 2-3 / / full penetration, forming a dense protective layer at the bottom.

[0014] Furthermore: the combs GB2 and GB3 are made of 75D / 36F nylon 66 filament.

[0015] Furthermore: GB5 uses 150D / 36F fully dull polyester low-elasticity yarn.

[0016] Furthermore, the combs JB4.1 and JB4.2 are made of 50D / 24F modified polyester monofilament.

[0017] Furthermore, the thickness of the fabric body is 0.8-1.5mm.

[0018] Furthermore: the weight of the fabric body is 180-250 g / m². 2 .

[0019] By adopting the aforementioned technical solution, the beneficial effects of this utility model are as follows:

[0020] 1. Comb JB4.1 and comb JB4.2 form a three-dimensional groove structure through symmetrical notched padding process. Together with the warp flat weave support layer (comb GB3), they form a three-dimensional flow channel. Liquids (such as rainwater and sweat) can be quickly and directionally discharged along the grooves, reducing the time that the fabric surface stays. Combined with the dense protective layer of the bottom full-dull polyester low elastic yarn (comb GB5), it achieves the dual function of "external protection and internal drainage".

[0021] 2. Comb GB2 uses a warp-pile weave, forming a dense pile layer through an all-through process. This results in a low surface friction coefficient and excellent abrasion resistance, superior to ordinary knitted fabrics. Comb GB5 uses a warp-satin weave, threaded with fully matte polyester low-elastic yarn. The all-through process forms a smooth and dense layer, preventing liquid penetration. At the same time, the matte treatment reduces light reflection and enhances the fabric texture.

[0022] 3. JB4.1 and JB4.2 adopt a 1-through-1-open design with a high open-through rate. While ensuring the strength of the flow channel, the overall density of the fabric is reduced. While achieving functions such as three-proof, flow-guiding, and wear-resistant, it maintains the lightweight characteristics. Attached Figure Description

[0029] The embodiment of this utility model is as follows:

[0030] refer to Figures 1 to 5 A three-proof and easy-to-clean knitted fabric includes a fabric body comprising a surface layer, a support layer, and a bottom layer, wherein the support layer is located between the surface layer and the bottom layer, and a three-dimensional flow channel is provided between the surface layer and the bottom layer; the fabric body is woven from at least five combs using a warp knitting process; comb GB2 adopts a warp-pile structure with a weave structure of 1-0-1-1 / 2-3-2-2 / / full weave, forming a dense pile structure on the surface of the fabric; comb GB3 adopts a warp-plain weave with a weave structure of 1-0 / 1-2 / / full weave, forming a middle layer... Support layer; Comb JB4.1 adopts a missing pad structure with a structure of 1-0-2-3 / 1-2-0-1 / / 1 through 1 open, forming a three-dimensional groove structure; Comb JB4.2 is symmetrically arranged with JB4.1, and Comb JB4.2 adopts a missing pad structure with a structure of 2-3-1-0 / 0-1-2-3 / / 1 through 1 open, together with JB4.1 forming a three-dimensional flow channel; Comb GB5 adopts a warp satin structure with a structure of 3-4 / 2-1 / 1-0 / 2-3 / / full through, forming a dense protective layer at the bottom.

[0031] Among them, the comb GB2 and comb GB3 are made of 75D / 36F nylon 66 filament 1, the GB5 is made of 150D / 36F fully dull polyester low elastic yarn 2, and the comb JB4.1 and JB4.2 are made of 50D / 24F modified polyester monofilament 3.

[0032] The modified polyester monofilament is produced by adding nano-SiO2 dispersion and PET chips at a mass ratio of 1:50 to a high-speed mixer and stirring at 800 rpm for 30 minutes at 80°C to ensure that the nanoparticles are uniformly attached to the surface of the chips. The pre-dispersed mixture is then added to a twin-screw extruder and melt-extruded at 260-280°C. The shear force of the screws ensures that the nano-SiO2 is uniformly dispersed in the PET matrix to form a nanocomposite masterbatch. The nanocomposite masterbatch is then immersed in a PFDS ethanol solution (5 wt%) and ultrasonically treated at 60°C for 2 hours to allow perfluorinated groups to be chemically bonded to the SiO2 surface, forming a hydrophobic-oleophobic dual-effect structure. Finally, the filament is spun using a high-speed melt spinning machine, and the filament is cooled by side blowing and subjected to multi-stage stretching after exiting the spinning machine.

[0038] IV. After weaving is completed, perform heat setting treatment: temperature 190℃, time 60 seconds;

[0039] V. Following the heat setting treatment, a plasma surface treatment process is added: using an O2 / CF4 mixed gas at a power of 200W for 3 minutes, the adhesion of the three-proof finishing layer is enhanced, resulting in a three-proof and easy-to-clean knitted fabric.
