Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fiber preparation, in particular to a tooth-shaped functional composite fiber multi-element combination die. BACKGROUND

[0002] With the progress of society and the improvement of people's living standards, new functional fiber products are becoming more and more popular. Traditional fiber products have single function and low added value, and cannot meet the current situation. Therefore, people's demand for functionalization and differentiation of fibers is increasing. Current composite fibers can achieve more functionalization and differentiation.

[0003] Composite fibers refer to chemical fibers made of two or more polymers or the same polymer with different properties by composite spinning method. In the cross section of the fiber, there are two or more components that do not mix. According to the structure, common composite fibers include side-by-side type, core-sheath type, island-in-sea type, and split type. Currently, general side-by-side and core-sheath fibers are composed of two polymers with different chemical structures or properties. Through the composite structure, functional monofilaments such as antibacterial, mosquito repellent, and micro-conductive can be achieved.

[0004] However, the fibers produced by the current core-sheath and side-by-side dies generally only have one or two functions, the functions are relatively single, and the application effect is greatly discounted due to the influence of specific surface area, surface energy and surface activity. It is difficult to produce high value-added products, and the function of the formed product is far lower than the application effect due to the influence of the material and structure itself, which greatly reduces the service life of the product itself.

[0005] At the same time, in the current composite fiber production process, due to problems such as insufficient structural strength and viscosity, it is easy to cause the composite fiber to appear phenomena such as opening and peeling. In the side-by-side composite fiber, it is difficult to bond two materials with too large thermal shrinkage difference. Once bonded, one of the fibers will shrink too much due to insufficient adhesion, which will cause the two fibers to peel off, and the two components of the fiber will easily diffuse on the interface, affecting the performance of the composite fiber.

[0070] Example 2

[0071] In the process of making composite fibers, first, the raw materials are divided into a main material and a plurality of functional auxiliary materials, wherein the main material is extruded by a separate extruder, transported to the composite mold through a separate pipeline, enters the central feed hole of the flow guide plates A7, B8, C9, D10 and E14 through the corresponding flow guide grooves, and after uniform buffering in the middle buffer zone, enters the buffer groove in the middle of the spinneret A1, and after uniform buffering, flows into the middle of the spinneret B through the feed holes in the buffer groove, and after uniform buffering through the buffer groove and the buffer table in the middle of the spinneret B, flows into the middle of the spinneret C through the feed holes, and the main material is shaped and made through the tooth-shaped feed holes in the middle of the spinneret C to form an intermediate base carrier;

[0072] Different functional auxiliary materials are added to different extruders, and by setting the respective temperature and pressure, they are transported to the composite mold through the respective pipelines, enter the outer ring feed holes of the flow guide plates B8, C9, D10 and E14 through the respective flow guide grooves, that is, the upper and lower buffer grooves provided on each layer of flow guide plate are uniformly buffered, and after a certain uniformity effect is achieved, they flow into the respective corresponding buffer grooves of the outer ring of the spinneret A1 through the feed holes in each buffer groove, and then pass through the buffer grooves in each spinneret mold for further uniform buffering, and pass through the feed holes in each buffer groove, such as flowing through the outer ring feed holes of the spinnerets D4, E5 and F6, and being added to the intermediate base carrier material. Figure 16As shown, one of the functional materials enters the flow average pressure cavity through the outer circle feed hole of spinneret C3, and is buffered and evenly pressured through the lower and upper buffer zones in the flow average pressure cavity between spinneret C3 and spinneret D4, so that the functional material can be evenly fused with the intermediate carrier to form a stable structure of the composite monofilament. In this way, other functional materials in the flow channel are continuously added in the next layer of spinneret mold for fusion. Specifically, according to market needs, cost management, and efficiency, etc., a plurality of layers of tooth-shaped structures can be divided.

[0073] The tooth-shaped structure of the composite monofilament can also be adjusted according to functional requirements and cost control. For example, as shown in the 1+8 structure, Figure 27 PET material is used as the main material to fill in the middle to form a tooth-shaped carrier base material. Around the tooth gap, 60% PE is added as the main material, and 40% high-proportion multi-functional masterbatch ingredients are mixed to form various functional materials such as antibacterial, sterilization, mosquito repellent, and micro-conductive materials, so that the monofilament has multiple functions.

[0074] According to the viscosity and the influence of temperature, the materials with small viscosity, fast flow rate, and large temperature change are sent to the upper layer of the spinneret in the inner circle of the mold for priority shaping; the materials with large viscosity, slow flow rate, and small temperature change are sent to the lower layer of the spinneret in the outer circle of the mold for shaping.

[0075] Through the design of the tooth-shaped structure, as shown in Figure 7 and Figure 31 , the interaction force between the intermediate carrier material and the functional additive material can be effectively increased, so that they can be tightly fused together without dispersion. For example, in the 1+8 structure, the depth of each tooth of the tooth-shaped structure is 0.6 mm, the tooth bottom distance is 0.17 mm, the tooth gap distance is 0.44 mm, and the tooth gear angle is 25.22°. Through the design of the tooth-shaped structure, the large depth and the different sizes of the two ends, and the gap between the teeth, the filled materials are squeezed between the teeth. Under the action of thermal expansion and cold contraction, by increasing the contact area, the depth and the angle, and relying on the friction force and the clamping force of the tooth-shaped structure, the multiple additive materials are tightly connected together. Figure 33 .

[0076] The thickness of the spinneret of the composite mold is about 15-22 mm per layer. The specific thickness is different according to the viscosity requirements of different materials. The thickness of the material with large viscosity is less than 18 mm, and the thickness of the material with small viscosity is greater than 18 mm. The last layer (the outlet layer) is thicker, between 20-25 mm. The diameter of the flow guide hole and the spinneret hole on the spinneret is φ1.0 mm-3.0 mm, including the tooth-shaped spinneret hole and the circular spinneret hole. The diameter is also determined according to the different materials and viscosities.

[0077] Flow average pressure cavity, also called flow flat groove, as shown in Figure 16 and Figure 30 , its main role is to mix the intermediate carrier material and a functional material evenly, prevent the two materials from insufficient and uneven fusion through buffer equalization and other ways. Its height is set between 3-6mm according to the viscosity of the material, the lower buffer zone depth is 1.5 times of the diameter of the material pipe, the upper buffer zone is between 0.5-1 times of the diameter of the material pipe, the flow flat zone length is 5 times of the diameter of the material pipe, the size is not less than the total of the upper and lower buffer zones, and the buffer zone edge is a round corner structure.

[0078] The whole composite fiber multi-element combination mold is placed in the biphenyl spinning box, and runs in a constant temperature state. The biphenyl spinning box is heated by a biphenyl furnace, and the temperature is kept at 260℃ to ensure that the various materials in a molten state can be uniformly and fully fused.

[0079] As shown in Figure 29 , each guide plate is connected to the material conveying pipe through its own guide groove in the lateral direction, and each buffer groove can play the role of buffering and guiding to prevent the phenomenon of dead angle paste, and the upper and lower guide grooves and the upper and lower buffer grooves can be disassembled for daily cleaning and maintenance.

[0080] Finally, the synthesized composite product yarn is obtained by adding electrospinning technology, using electric field force and machine pressure to make the monofilament run stably, prevent the outlet from being blocked, and then perform cooling and stress relief processes to obtain the composite functional product yarn.

[0081] Among them, the specific process flow of synthesizing composite fiber yarn has been applied for an invention patent, and will not be described in detail here.

[0082] The above shows and describes the basic principles and main features of the present application and the advantages of the present application. The components mentioned in the present application are common techniques in the existing field, and those skilled in the art should understand that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the present application.
