[0044] The following will discuss various embodiments of the present disclosure in more detail. However, this embodiment can be an application of various disclosed concepts and can be specifically implemented in various specific scopes. The specific embodiments are for illustrative purposes only and are not limited to the scope of the disclosure. In addition, in order to simplify the drawings, some existing conventional structures and elements will be shown in the drawings in a simple schematic manner.

[0045] Please refer to Figure 1 , Figure 1 1 is a flow chart of the steps of the method 100 for preparing a multifilament structure of the present disclosure. The method 100 for preparing a multifilament structure comprises step 110 , step 120 , step 130 and step 140 .

[0046] In detail, step 110 is to provide a raw material of the thread, which can be selected from a group consisting of nylon, polypropylene and cationic dyeable polyester, so different material combinations can be configured according to the use requirements. Before the subsequent steps, the raw material of the thread can be dried at a drying temperature of 150° C. to 180° C. to remove the moisture that may be contained in the raw material of the thread.

[0047] Step 120 is to spin the raw material of the silk thread to obtain a plurality of fibers. The raw material of the silk thread can be spun at a spinning temperature of 250° C. to 290° C. and a spinning pressure of 80 kg to 120 kg, and the spinning temperature and the spinning pressure are adjusted according to the material properties and actual needs. The raw material of the silk thread can be spun through a screw extruder, a spinning box and a spinneret to form the plurality of fibers. The number of the plurality of fibers can be 4 to 12, and the fineness of each fiber can be 10 d to 50 d, so as to facilitate the subsequent formation of a multifilament structure.

[0048] Step 130 is to twist the plurality of fibers to obtain a twisted structure, and the twisted structure still needs to be completely fixed in shape through a subsequent shaping step. Furthermore, when the plurality of fibers are twisted, the plurality of fibers can be preliminarily cooled at a preliminarily cooling temperature of 10° C. to 30° C. The preliminarily cooling step can be performed depending on the type of material, fiber properties, or processing status, and can be used to adjust the properties of the plurality of fibers or the twisted structure, so the present disclosure is not limited to the preliminarily cooling step.

[0049] Step 140 is to wind the twisted structure to obtain a multifilament structure, wherein the twisted structure may be cooled and shaped at a cooling and shaping temperature of 10° C. to 30° C. before winding. By winding the yarn after twisting, the production time can be shortened, the loss and production cost can be reduced, and the elasticity and bending properties of the multifilament structure can be improved.

[0050] The method 100 for preparing a multifilament structure may further include performing a moisture restoration treatment on the multifilament structure before winding the yarn. The moisture restoration treatment may be performed at a moisture restoration temperature of 10°C to 60°C, or at a moisture restoration temperature of 10°C to 30°C, or at a moisture restoration temperature of 20°C to 60°C, so as to strengthen the tension of the multifilament structure. The method 100 for preparing a multifilament structure may further include performing a heat treatment on the multifilament structure before winding the yarn. The heat treatment may be performed at a heating temperature of 100°C to 180°C, so as to further stabilize the physical properties of the multifilament structure. The aforementioned moisture restoration treatment and heat treatment may be performed one or more times as required, and the present disclosure is not limited to the number of the above-mentioned treatments.

[0051] Please refer to Figure 2 , Figure 2The schematic diagram of the structure of a multifilament structure manufacturing device 200 according to an embodiment of the present disclosure includes a screw extruder 210, a spinning box 220, a spinneret 230, a yarn doubling device 240 and a yarn winding device 250 connected in sequence.

[0052] In detail, the screw extruder 210 has a feed port 211 and a discharge port 212 that are connected to each other, and the spinning box 220 is connected to the discharge port 212 of the screw extruder 210. The manufacturing equipment 200 of the multifilament structure may further include a feed hopper 260, and the feed hopper 260 may be connected to the feed port 211 of the screw extruder 210. Accordingly, the feed hopper 260 can be used to fill the wire raw material, so that the wire raw material enters the screw extruder 210 from the feed port 211, is heated and melted, and forms a melt and is extruded from the discharge port 212 of the screw extruder 210.

[0053] A surface 221 of the spinning box 220 has a plurality of spinning outlets (not numbered), the number of which may depend on the number of fibers in the multifilament structure. The spinning box 220 may form a plurality of fibers from the filament raw material melt from the screw extruder 210, and the plurality of fibers may be respectively sent out from the plurality of spinning outlets. For example, the number of the plurality of spinning outlets may be 4 to 12, but the present disclosure is not limited to the above number.

[0054] The spinneret 230 has a plurality of spinneret holes 231, and the plurality of spinneret holes 231 are respectively located at the plurality of spinning outlets, that is, the spinneret 230 may be adjacent to the surface 221 of the spinning box 220, or may be directly connected to the surface 221, so that the plurality of fibers can pass through. The number of the plurality of spinneret holes 231 may be the same as the plurality of spinning outlets, so the number of the plurality of spinneret holes 231 may also be 4 to 12. In addition, the positions of the plurality of spinneret holes 231 on the spinneret 230 may be arranged in a circle and distributed at equal angles, or one of the spinneret holes 231 may be located at the center of the spinneret 230, and the remaining spinneret holes 231 may be arranged around the spinneret hole 231 at the center. According to the setting positions of the plurality of spinneret holes 231, multifilament structures of different forms can be twisted, so the setting positions of the plurality of spinneret holes 231 may be adjusted as required, and the present disclosure is not limited thereto.

[0055] The doubling device 240 is connected to the multiple spinnerets 231 to twist the multiple fibers into a twisted structure. The doubling device 240 can be connected to the multiple spinnerets 231 through a preliminary cooling device 270, a cooling and shaping device 291 and a first moisture-recovery treatment device 292, and the manufacturing equipment 200 of the multifilament structure can further include an air supply device 280, which can be connected to the preliminary cooling device 270, and the air supply device 280 is used to send cold air into the preliminary cooling device 270, thereby preliminarily cooling the multiple fibers. The cooling and shaping device 291 can be connected to the preliminary cooling device 270, and the first moisture-recovery treatment device 292 can be connected to the cooling and shaping device 291 to perform secondary cooling and moisture-recovery treatment on the multiple fibers, which helps to improve the elasticity and bending properties of the multiple fibers after twisting.

[0056] The winding device 250 is connected to the doubling device 240 to wind the twisted structure. By winding the yarn after twisting, the production time can be shortened, the loss and production cost can be reduced, and the elasticity and bending properties of the multifilament structure can be improved.

[0057] Please refer to Figure 3 , Figure 3 Schematic diagram of the structure of a multifilament structure manufacturing device 200 and a back-end processing device 300. The doubling device 240 and the winding device 250 in the multifilament structure manufacturing device 200 can be connected to the back-end processing device 300 respectively, so that the twisted structure prepared by the doubling device 240 can be processed in the back end, and then the yarn can be wound after processing.

[0058] In detail, the back-end processing equipment 300 may include a first heating treatment device 310, a second moisture recovery treatment device 320 and a second heating treatment device 330 in sequence, and the multifilament structure may pass through the above devices in sequence for back-end processing, wherein the moisture recovery treatment and heating treatment of the multifilament structure have been introduced in the previous paragraphs and will not be repeated here.

[0059] Please refer to Figure 4 , Figure 4 FIG. 4 is a schematic structural diagram of a multifilament structure 400 according to another embodiment of the present disclosure. Figure 5 for Figure 4 Another structural schematic diagram of a multifilament structure 400. The multifilament structure 400 is prepared by the aforementioned multifilament structure preparation method 100 or multifilament structure manufacturing device 200, and comprises a plurality of fibers 410, and the plurality of fibers 410 are twisted and spirally wound with each other. The number of the plurality of fibers 410 can be 4 to 12, and the fineness of each fiber 410 can be 10d to 50d, and the number or fineness of the fibers 410 can be adjusted according to the use requirements, or the twisting degree of the multifilament structure 400 can be adjusted, so the content of the present disclosure is not limited to the above range.

[0060] Another embodiment of the present disclosure provides a fabric, which is woven from the aforementioned multifilament structure 400, and the fabric has a plain weave structure or a knitted structure. The fabric prepared from the multifilament structure 400 can have high tensile strength, bending resistance and wear resistance, so the strength of the fabric can be greatly increased and its service life can be extended.
