Description

Technical Field

[0001] This invention relates to the field of wastewater treatment, specifically to a fast-permeable and high-efficiency fiber fabric and its preparation method. Background Technology

[0002] Fiber materials play an important role in wastewater treatment. As filter media or biological carriers, they can effectively remove pollutants from wastewater and improve water quality.

[0003] With social development, various fiber materials suitable for sewage treatment have entered the market. However, the use of a single fiber material for filtration often leads to a discrepancy between filtration performance and service life during sewage treatment. Fiber materials with good filtration effects but poor permeability are often unsatisfactory, while those with good permeability have short service lives, resulting in increased costs for fiber filtration. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a quick-diffuse and high-efficiency fiber fabric and its preparation method, which has advantages such as higher quick-diffuseness and solves the problems mentioned in the background technology.

[0005] To achieve the aforementioned goal of better breathability, the present invention provides the following technical solution: a breathable and efficient fiber fabric and its preparation method, comprising polyester fiber, polyamide fiber, polypropylene fiber, moisture-wicking fiber and natural fiber.

[0006] Preferably, it includes the following steps:

[0007] S1. Pre-clean the fiber raw materials, and then dry them using a dryer.

[0008] S2. After drying, the raw materials are put into the opening machine to open the fiber raw materials and obtain the opened fiber bundles.

[0009] S3. After opening, impurities in the fiber bundles are manually removed.

[0010] S4. The clean and tidy fiber bundles are combed using a combing machine;

[0011] S5. After combing, the various fiber materials are placed into a web forming machine for processing;

[0012] S6. The fiber material after web formation is needle-punched.

[0013] S7. After needle punching, a semi-finished product is obtained. The semi-finished product is then washed and dried to obtain the finished product.

[0014] Preferably, the polyester fiber is a polyester air layer fiber, the polyamide fiber is an aliphatic polyamide fiber, the moisture-wicking fiber is polyester fiber, and the natural fiber is a plant fiber. The polyester air layer fiber has a hollow structure with a large number of air pores inside, which can greatly improve the breathability of the fabric. The aliphatic polyamide fiber has high strength, which can greatly extend the service life of the fabric. The polyester fiber has good abrasion resistance and corrosion resistance, which can also play a role in improving the actual service life of the fabric.

[0015] Preferably, the ratio of polyester fiber, polyamide fiber, polypropylene fiber, moisture-wicking fiber and natural fiber is 3:3:2:1:1. By using different proportions of fiber materials, fibers with good breathability can be obtained. The higher proportion of polyester fiber can ensure that the fabric has both good stability and high breathability. Since most of the fiber materials used are hydrophilic fibers, the overall breathability of the fabric is greatly enhanced, allowing wastewater with complex molecules to be filtered better.

[0016] Preferably, the web forming process in step S5 is carried out in batches to obtain polyester fiber web, polyamide fiber web, polypropylene fiber web, moisture-wicking fiber web and natural fiber web.

[0017] Preferably, the needle punching process in step S6 is performed in batches, and the fiber layers after needle punching are stacked and laid out. After stacking and laying out, needle punching is performed again to obtain a semi-finished fiber layer. The stacking order of the fiber web is polyester air layer fiber, aliphatic polyamide fiber, polyester fiber and plant fiber. The plant fiber is the outer surface of the filter and can be made of long-staple cotton as the main raw material. During use, the fine velvet can intercept most of the lint. At the same time, since the polyester air layer fiber is placed on the outermost layer, the overall fiber layer's rapid permeability is guaranteed, ensuring the flow rate during sewage filtration.

[0018] Preferably, the gap between the polyester fibers during the needle punching process is slightly larger than that between the polyamide fibers, polypropylene fibers, moisture-wicking fibers, and natural fibers. The larger needle punching gap can increase the air flow in the polyester air fibers, thereby increasing the air circulation inside the fabric fibers and greatly shortening the drying time of the fabric.

[0019] Compared with the prior art, the present invention provides a fast-breathing and high-efficiency fiber fabric and its preparation method, which has the following beneficial effects:

[0020] This fast-permeable and high-efficiency fiber fabric and its preparation method, through a larger proportion of polyester fibers, leverage the hydrophilicity and permeability of polyester fibers to achieve optimal fast permeability while maintaining a certain strength. This makes the fabric more suitable for wastewater filtration, significantly extending its service life compared to existing conventional filter fiber fabrics. During conventional wastewater filtration, the improved fast permeability of the fibers greatly enhances the filtration efficiency. Furthermore, the increased fast permeability significantly improves the filtration efficiency of oil-water mixtures or flocculent matter. While ensuring water permeability, it also guarantees the overall fabric's corrosion resistance, greatly expanding its applicability to wastewater treatment. Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention. Example 1

[0022] The preferred embodiment of the quick-drying and high-efficiency fiber fabric and its preparation method provided by the present invention is as follows: A quick-drying and high-efficiency fiber fabric and its preparation method include polyester fiber, polyamide fiber, polypropylene fiber, moisture-wicking fiber and natural fiber.

[0023] This embodiment includes the following steps:

[0024] S1. Pre-clean the fiber raw materials, and then dry them using a dryer.

[0025] S2. After drying, the raw materials are put into the opening machine to open the fiber raw materials and obtain the opened fiber bundles.

[0026] S3. After opening, impurities in the fiber bundles are manually removed.

[0027] S4. The clean and tidy fiber bundles are combed using a combing machine;

[0028] S5. After combing, the various fiber materials are placed into a web forming machine for processing;

[0029] S6. The fiber material after web formation is needle-punched.

[0030] S7. After needle punching, a semi-finished product is obtained. The semi-finished product is then washed and dried to obtain the finished product. Example 2

[0031] Based on Example 1, the preferred embodiment of the breathable and efficient fiber fabric and its preparation method provided by the present invention is as follows: the polyester fiber is a polyester air layer fiber, the polyamide fiber is an aliphatic polyamide fiber, the moisture-wicking fiber is polyester fiber, and the natural fiber is a plant fiber. The polyester air layer fiber has a hollow structure with a large number of air pores inside, which can greatly improve the breathability of the fabric. The aliphatic polyamide fiber has high strength, which can greatly extend the service life of the fabric. The polyester fiber has good abrasion resistance and corrosion resistance, which can mainly enhance the actual service life of the fabric.

[0032] In this embodiment, the ratio of polyester fiber, polyamide fiber, polypropylene fiber, moisture-wicking fiber, and natural fiber is 3:3:2:1:1. By using different proportions of fiber materials, fibers with good breathability can be obtained. The higher proportion of polyester fiber ensures that the fabric has both good stability and high breathability. Since most of the fiber materials used are hydrophilic fibers, the overall breathability of the fabric is greatly enhanced, allowing wastewater with complex molecules to be filtered better.

[0033] Furthermore, the web forming process in step S5 is carried out in batches to obtain polyester fiber web, polyamide fiber web, polypropylene fiber web, moisture-wicking fiber web and natural fiber web.

[0034] Furthermore, the needle punching process in step S6 is performed in batches, and the fiber layers after needle punching are stacked and laid out. After stacking and laying out, needle punching is performed again to obtain a semi-finished fiber layer. The stacking order of the fiber web is polyester air layer fiber, aliphatic polyamide fiber, polyester fiber and plant fiber. The plant fiber is the outer surface of the filter and can be made of long-staple cotton as the main raw material. During use, the fine velvet can intercept most of the lint. At the same time, since the polyester air layer fiber is placed on the outermost layer, the overall fiber layer's rapid permeability is guaranteed, ensuring the flow rate during sewage filtration.

[0035] In addition, the gaps in the needle punching process of polyester fibers are slightly larger than those of polyamide fibers, polypropylene fibers, moisture-wicking fibers, and natural fibers. The larger needle punching gaps can increase the air flow in polyester air fibers, thereby increasing the air circulation inside the fabric fibers and greatly shortening the drying time of the fabric.

[0036] In summary, this fast-permeable and high-efficiency fiber fabric and its preparation method, through a larger proportion of polyester fibers, enable the overall fiber fabric to achieve optimal fast permeability and permeability while ensuring a certain strength. This makes the overall fabric more suitable for wastewater filtration and significantly extends its service life compared to existing conventional filter fiber fabrics.
