Description

Technical Field

[0001] This application relates to the technical field of fabric production equipment, and in particular to a production equipment for irregularly shaped needle plates, double-sided textured fabrics, and double-sided textured fabrics. Background Technology

[0002] Nonwoven fabric is a type of non-woven material made by interlocking fibers through methods such as entanglement, friction, tearing, and melting. It can also be toughened and bonded through mechanical, thermal, or chemical methods. Nonwoven fabrics are soft, breathable, and durable, and are widely used in various fields such as medical, hygiene, packaging, home furnishing, and agriculture.

[0003] In existing technologies, hydroentangled fabrics are produced using a rotary drum hydroentanglement production device. Hydroentanglement heads are arranged circumferentially along the drum, and the fiber web adheres to the drum, receiving the water jets emitted from the heads. Hydroentanglement needle plates are positioned on the drum; the water jets from the heads hit the fiber web and then strike the needle plates. At this point, the corresponding small holes on the needle plates are pierced by high-pressure water needles, forming a texture. The side of the fiber web closest to the drum has no texture protrusion, while the other side (away from the drum) forms a texture. For example, in pearl-textured nonwoven fabric, the protruding pearl-textured side is the side away from the drum, while the flat side is the side closest to the drum. Therefore, only a single-sided effect can be achieved: for example, in pearl-textured fabric, one side is raised, and the other side is flat, thus a double-sided textured fabric cannot be obtained.

[0004] Therefore, this application provides a production apparatus for irregularly shaped needle plates, double-sided textured fabrics, and double-sided textured fabrics. Utility Model Content

[0005] To overcome the shortcomings of the prior art, this application provides a special-shaped needle plate, a production device for double-sided textured fabric, and a double-sided textured fabric. The special-shaped needle plate is set inside the hydroentanglement head and is divided into a hydroentanglement processing area and a non-hydroentanglement processing area. By using the special-shaped needle plate, the spray state of the high-pressure water jet is changed, so that the nonwoven fabric presents a tight area and a fluffy area, thereby achieving a double-sided textured effect.

[0006] The technical solution adopted by this application to solve its technical problem is:

[0007] The primary objective of this application is to provide a shaped needle plate disposed within a hydroentanglement head, wherein the shaped needle plate is provided with a hydroentanglement processing area and a non-hydroentanglement processing area.

[0008] In some specific embodiments, the hydroentangled processing area is distributed with several groups of hydroentangled needle holes, and the spacing between the groups of hydroentangled needle holes is 2-3 mm; the diameter of the hydroentangled needle holes in the hydroentangled processing area is 0.1-0.2 mm.

[0027] The following will clearly and completely describe the concept, specific structure, and resulting technical effects of this application in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this application. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are all within the scope of protection of this application. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this application can be combined interactively without contradicting each other.

[0028] The standard needle plate is located on the rotating drum, without distinguishing between the processed and unprocessed areas. The resulting texture has two styles: ① Perforated type, such as mesh, with the same texture on both sides, lacking three-dimensionality; ② Unperforated type, such as pearl texture, with one side having a pearl texture and the other side having a flat texture (the side closest to the rotating drum has a flat texture).

[0029] To address the technical problem that conventional needle plates cannot produce double-sided textured fabrics, such as Figure 1 The present application provides a shaped needle plate, which is disposed inside the hydroentangle head 2. The shaped needle plate 1 is provided with a hydroentangle processing area 11 and a non-hydroentangle processing area 12.

[0030] Specifically, the irregularly shaped needle plate is located inside the hydroentangle head, which changes the spraying state of the high-pressure water needles. The corresponding needle holes on the irregularly shaped needle plate are where the water needles are ejected, which is called the hydroentangled processing area. On the nonwoven fabric, this corresponds to the compact area. The areas without needle holes do not have high-pressure water needles ejected, which are called the non-hydroentangled processing area, which corresponds to the fluffy area on the nonwoven fabric.

[0031] In some embodiments, the hydroentangling processing area 11 is provided with a plurality of groups of hydroentangling needle holes 13, the spacing between the groups of hydroentangling needle holes 13 is 2-3 mm; the diameter of the hydroentangling needle holes 13 in the hydroentangling processing area 11 is 0.1-0.2 mm.

[0032] Therefore, by controlling the distribution and spacing of the hydroentangling needle holes, point hydroentangling is achieved. That is, high-pressure water jets are applied at the positions corresponding to the hydroentangling needle holes, causing the fibers to entangle and form a compact area; while the areas not directly affected by the water jets remain fluffy, forming a fluffy area. This contrast enhances the texture and three-dimensionality of the product.

[0033] In some embodiments, the hydroentangled area 11 and the non-hydroentangled area 12 on the irregular needle plate 1 are arranged alternately.

[0034] Specifically, the non-spunlace and spunlace areas are arranged alternately. This area has no spunlace needle holes, so no high-pressure water jets are ejected. This means that the fibers in this area are not treated by high-pressure water jets, thus maintaining their original fluffy state and forming a fluffy zone. The fibers in the fluffy zone maintain their fluffy state, providing the fabric with a better hand feel and thickness.

[0035] In some embodiments, the irregularly shaped needle plate 1 is used to perform hydroentangling treatment on the textile fibers after web laying.

[0036] Specifically, by setting irregularly shaped needle plates inside the hydroentanglement head and distinguishing between the hydroentangled and non-hydroentangled areas, different texture effects can be created on both sides of the nonwoven fabric. The fibers in the hydroentangled area are tightly entangled under the action of the hydroneedles, forming a compact zone; while the fibers in the non-hydroentangled area remain loose, forming a fluffy zone. This results in a clear difference in texture between the two sides of the nonwoven fabric, creating a double-sided texture.

[0037] like Figure 2 The production apparatus for the double-sided textured fabric 900 shown includes a hydroentangling device 100, which includes a hydroentangling head 2, and the hydroentangling head 2 is provided with the aforementioned irregular needle plate 1.

[0038] A hydroentanglement head is a device that sprays high-pressure water jets. It is fixed to the hydroentanglement equipment and contains shaped needle plates inside. Through the hydroentanglement head, high-pressure water is evenly sprayed onto the nonwoven fabric, working in conjunction with the shaped needle plates to complete the entanglement of fibers and the formation of texture.

[0039] In some embodiments, the production apparatus further includes a combing device 200, a web-laying device 300, and a pre-sting device 400, wherein the combing device 200 is connected to the web-laying device 300, the web-laying device 300 is connected to the pre-sting device 400, and the pre-sting device 400 is connected to the hydroentangling device 100.

[0040] Specifically, carding equipment finely combs raw fiber (such as cotton) to remove impurities (such as cottonseed hulls, trifilaments, etc.) and combs the aggregated fiber clumps into individual fibers, providing uniform and fine fiber raw materials for subsequent processes.

[0041] The web-laying equipment randomly overlaps and spreads the combed individual fibers into a loose web structure. This step is to form a fiber web with a certain thickness and uniformity, preparing it for subsequent hydroentanglement reinforcement.

[0042] Pre-punching equipment pre-treats the original dry fiber web, transforming it into a wet state and applying a certain water pressure to initially form the structure of the nonwoven fabric. The pre-punching process can reduce fuzzing and lint shedding on the fabric surface, improving the surface quality of the product.

[0043] The hydroentangling equipment (including shaped needle plates) ultimately uses the penetrating action of high-pressure water needles to entangle and reinforce the loose fiber web, forming a nonwoven fabric product with specific texture and strength.

[0044] In some embodiments, the production apparatus further includes a debleaching device 500 and a drying device 600, wherein the hydroentanglement device 100 is connected to the debleaching device 500 and the debleaching device 500 is connected to the drying device 600.

[0045] The main purpose of debleaching equipment is to remove impurities and chemical residues (such as cotton wax, pectin, etc.) from nonwoven fabrics after hydroentanglement treatment, thereby improving the purity and quality of the nonwoven fabrics.

[0046] Drying equipment is used to remove a large amount of moisture from nonwoven fabrics after debleaching, so that they reach a certain degree of dryness, which facilitates subsequent processing, storage and use.

[0047] In some embodiments, such as Figure 3 The hydroentangling device 100 shown also includes a rotating drum 3, which is disposed below the hydroentangling head 2.

[0048] The rotating drum, located below the hydroentangling head, feeds the nonwoven fabric into the hydroentangling area. During the hydroentangling process, high-pressure water jets are ejected from the hydroentangling head, penetrate the nonwoven fabric, and interact with the needle plates on the rotating drum to form the desired texture. The rotation and stability of the drum are crucial for ensuring the hydroentangling effect and the uniformity of the texture.

[0049] like Figure 4 The double-sided textured fabric 900 shown is a fabric produced by the production device described above.

[0050] In some embodiments, each side of the double-sided textured fabric 900 is provided with a fluffy area 9001 and a firm area 9002 at intervals.

[0051] The production apparatus for the double-sided textured fabric described in this application operates as follows:

[0052] Opening and cleaning: First, the entire bale of cotton is opened to loosen it. Then, the cotton cleaning process removes impurities such as cottonseed hulls and fibrous materials from the raw cotton to ensure fiber purity.

[0053] Mixing and carding: The cleaned fibers are mixed to improve fiber uniformity; then, the mixed fibers are sent to a carding machine (carding equipment) for carding, which cardes the aggregated fiber clumps into individual fibers, in preparation for subsequent web laying.

[0054] Web laying: The combed fibers are randomly scattered and overlapped by a web laying device to form a loose web structure, thus forming a fiber web.

[0055] Pre-punching: The original dry fiber web (in the pre-punching equipment) is pre-treated to make it wet and a certain water pressure is applied to initially form a nonwoven fabric, reducing the occurrence of fuzzing and shedding on the fabric surface.

[0056] Hydroentangling: The hydroentangling head in the hydroentangling equipment is equipped with a shaped needle plate, which is divided into a hydroentangling processing zone and a non-hydroentangling processing zone. High-pressure water jets are ejected through the hydroentangling needle holes in the hydroentangling processing zone, penetrating the fiber web and causing the fibers at the corresponding positions to entangle and form a compact area; while no water jets pass through the non-hydroentangling processing zone, and the fibers remain in a loose state, forming a loose area. In this way, a double-sided texture is formed on the fiber web.

[0057] Debleaching and Drying: The spunlace nonwoven fabric undergoes debleaching to remove impurities and cotton wax, pectin, etc. from the cotton fibers. Subsequently, the nonwoven fabric is dried to the appropriate moisture content using drying equipment.

[0058] Slitting into rolls: Finally, the dried nonwoven fabric is slitted according to product specifications and rolled into rolls for easy storage and transportation.

[0059] The above is a detailed description of the preferred embodiments of this application. However, the invention of this application is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of this application. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
