Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, specifically to a breathable and anti-clogging cotton board matrix structure. Background Technology

[0002] In the spinning process, to reduce static electricity and improve fiber spinnability, the workshop environment is typically maintained at high humidity. When cotton boards are used as filters or airflow guiding elements in this environment, they face even greater challenges than traditional cotton boards:

[0003] 1. Moisture absorption and compaction: High humidity causes hygroscopic fibers such as cotton to absorb moisture rapidly, resulting in softening and swelling of the fibers, which then stick together, causing the porosity of the cotton board to drop sharply and loss of air permeability.

[0004] 2. Mold growth: After absorbing moisture, the cotton board becomes a breeding ground for mold and microorganisms, which not only produce odors and contaminate the yarn, but the mycelium will also further block the pores and damage the material structure.

[0005] 3. Fiber entanglement during spinning: The increased stickiness of the wet cotton board surface makes it easier for short fibers and fly ash generated during spinning to adhere to the windward side of the cotton board, forming a dense covering layer and accelerating blockage.

[0006] 4. Structural collapse: The combined effects of moisture absorption and microorganisms can degrade fiber strength. Under long-term airflow and vibration, the cotton board structure is prone to collapse and lose its function.

[0007] Therefore, existing cotton boards used in spinning equipment generally suffer from problems such as frequent replacement, high maintenance costs, and impact on yarn quality. Utility Model Content

[0008] In view of the shortcomings of the prior art, this utility model provides a breathable and anti-clogging cotton board matrix structure, which overcomes the shortcomings of the prior art and solves the problems mentioned in the background art.

[0009] To achieve the above objectives, this utility model provides the following technical solution: a breathable and anti-clogging cotton board matrix structure, comprising a plate-shaped body formed by the stacking of hydrophobic synthetic fibers, wherein the plate-shaped body is divided into a windward surface layer, an intermediate flow guiding layer and a leeward surface layer along its thickness direction, with the density relationship being windward surface layer < intermediate flow guiding layer < leeward surface layer; the intermediate flow guiding layer is provided with a through flow guiding channel; its special feature is that the surface of the windward surface layer is also covered with an anti-adhesion coating.

[0010] As a preferred embodiment of this invention, the hydrophobic synthetic fiber is polypropylene fiber or polyester fiber treated with a permanent hydrophobic finishing agent.

[0011] As a preferred embodiment of this invention, the hydrophobic synthetic fiber is blended with antibacterial masterbatch.

[0012] As a preferred embodiment of this invention, the anti-adhesion coating is composed of polytetrafluoroethylene micro powder or organosilicon resin material.

[0013] As a preferred technical solution of this utility model, the flow guiding channel is a frustum-shaped channel with its larger opening facing the windward side and its smaller opening facing the leeward side, and the inner wall of the channel is also covered with an anti-adhesion coating.

[0014] As a preferred technical solution of this utility model, the four edges of the plate-shaped body are bonded to the edge-sealing frame with sealant. The edge-sealing frame is preferably ABS plastic or corrosion-resistant aluminum alloy to form a moisture-proof and sealed structure.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. By using hydrophobic fibers such as polypropylene, the problems of moisture absorption, caking, and mold growth are eliminated from the material itself, ensuring the long-term structural stability and breathability of the matrix in high-humidity environments.

[0017] 2. The anti-adhesion coating makes the surface of the cotton board smooth, making it difficult for spinning fly and short fibers to adhere firmly. They are easily removed during equipment cleaning, greatly delaying surface clogging. The gradient density structure and the flow channel work together to achieve gradient interception of pollutants and multi-path passage of airflow. Even if there is partial coverage on the surface, the core airflow remains unobstructed.

[0018] 3. Combining multiple advantages such as hydrophobic materials, non-stick surfaces, structural flow guidance, and edge sealing, the overall cotton board has significantly improved durability in harsh spinning environments and extended replacement cycles.

[0019] 4. A clean cotton board prevents the yarn from being contaminated by mold and dust, ensuring the production of high-quality yarn. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-2 A breathable and clog-resistant cotton board substrate structure includes a board-shaped body 1 and an edge-binding frame 2.

[0025] The plate-shaped body 1 is made of polypropylene short fibers and integrally formed through gradient carding and hot-melt processes. A small amount of antibacterial masterbatch is mixed in. The formed plate-shaped body 1 has three functional layers with gradually changing density along its thickness direction: a loose windward surface layer 11, a moderately dense intermediate flow guiding layer 12, and a dense leeward surface layer 13. Within the intermediate flow guiding layer 12, multiple frustum-shaped flow guiding channels 121 are formed in a matrix-like uniform arrangement through hot pressing with a mold.

[0026] The outer surface of the windward layer 11 of the plate-shaped body 1 and the inner wall of all the flow channels 121 are coated with a polytetrafluoroethylene (PTFE) anti-adhesion coating through a spraying and curing process.

[0027] The four edges of the plate-shaped body 1 are firmly bonded to an ABS plastic edging frame 2 with epoxy resin sealant to ensure the airtightness and moisture resistance of the entire cotton board structure.

[0028] Working Principle: When high-temperature and high-humidity air flows through this cotton board in the spinning workshop, it will not absorb moisture or deform due to the hydrophobic nature of the matrix material. When fly filaments and short fibers impact the windward surface with the PTFE coating, they are not easily adhered, and some will slide or fall off under the influence of airflow. Airflow and particles enter the interior of the cotton board through the guide channel 121 and the fiber gaps, where they are filtered by a gradient. The guide channel 121 ensures a low-resistance core ventilation path, and even if there is fly filament accumulation on the surface after long-term use, it will not be completely blocked. The entire structure effectively resists the adverse effects of high humidity and fly filaments, achieving long-term stable operation.
