[Embodiment] Prior to the present invention, other technical contents, features, and effects of the following reference drawings will be apparent. In the detailed description of the preferred embodiment, referring to FIG. 1 and FIG. 2, a preferred embodiment of the invention is a method for manufacturing a non-woven fabric sheet. The manufacturing method has a flow guiding structure. The non-woven layer is carried out in 3, which comprises the following steps: a sudden visit to the spinning device 2 and a melt-blown spinning molten polymer raw material. Referring to Figure 2, this step is to simultaneously feed the polymer material into the spinning point. Bucket 21,... The extrusion screw 22 of the material of the spun-spinning device 2 and the melt-blown spinning device 3 utilizes the spun-spinning device 2 and the melt-blown spinning device 3: = after:::=:_*, - Dan A through melt filtration and melt metering. Step 12. The molten polymer raw material is drawn into a spun fiber. Referring to Fig. 2, the molten polymer raw material in the spunbonding spinning device 2 is smelted into the squirting m, squirting 4 device 3, and then it is drawn into a spun fiber 1 raw material = ΓΓΓ, § ( ΡΕΤ), nylon (muscle kiss..., medium, the molten polymer raw (4) unit 23 in the spunbonding spinning device 2 is drawn by cooling, that is, under the action of the air conditioner W wind, it is drawn into a continuous length. The fiber, that is, the molten polymer raw material forming the spun spinning fiber 201240651 and in the melt-blown spinning device 3, is drawn by a spinning unit 33 through a hot air, that is, under the action of a high temperature gas. The fine fiber 'is formed into a melt-blown spun fiber. Step 13: The laminated spun fiber is formed into a thin layer 5 having a flow guiding structure in a molding die 4. In this embodiment, the spun-bonded spinning is first performed. The fiber is laminated on the forming mold 4 to form a spunbond web layer, and then the melt-blown spun fiber is further laminated on the spunbond web layer to form a meltblown fiber web layer, and the meltblown fiber web layer and the spunbond layer The fiber web layers are combined to form a thin layer 5. Referring to Figure 3, Figure 4, the embodiment used in this embodiment The mold 4 includes a first forming layer 41 in the form of a stencil and a second forming layer 42 stacked on the __ forming layer, and the forming die 4 of the present embodiment is sleeved on the drum 43 The displacement of the drum 43 is similar to that of the conveyor belt. The first molding layer 41 has a plurality of meshes 411, and the second molding layer 42 has a plurality of connected ribs 421 structure. When the second molding layer 42 is stacked on the first When the molding layer 41 is formed, the rib 421 and the mesh 411 form the uneven structure of the molding die 4. The structure of the molding die 4 is merely an exemplary description. Of course, the structure of the molding die* is a flow guiding structure formed on the thin layer as needed. The molding die 4 is not limited to the above-mentioned structure. The molding die 4 is located on the inner side of the first molding layer 41 and further has a negative pressure unit 6'. When the spunbonded spinning fiber and the solvent-spun spinning fiber are successively layered on the molding die 4 At this time, since the spunbonded spun fiber and the meltblown spun fiber still have a certain high temperature and have not been completely hardened, the 'negative pressure provided by the negative pressure unit 6 can be used to make the spunbonded fiber and the melt blown. Spinning fibers are easier to adhere to each other 6 201240651 Forming a thin layer 5, this Another function of the negative pressure unit 6 is that since the layered spunbond web layer and the meltblown fiber web layer also have a certain degree of softness, the adsorption by the negative pressure unit 6 is also It is easy for the thin layer 5 to undulate with the rib 421 of the Jack 4 (four) into a plurality of ribs 51 and a recessed portion 52 defined by the ribs 51, which is the flow guiding structure. Since the spunbonded spun fiber and the meltblown spun fiber are successively layered in the forming die 4, the spunbonded web layer formed by the first layer can be formed on the forming die 4 after the flow guiding structure corresponding to the concave and convex structure is formed. When the melt-blown fiber web layer formed by the layer is combined with the spunbond fiber web layer, a flow guiding structure corresponding to the concave-convex structure is formed, in other words, when the spunbonded fiber web layer and the melt-blown fiber web layer are respectively formed on the forming mold 4 At the time, the diversion is formed separately. The structure of the spunbonded fibrous web formed by the first layer may be formed by the fact that the melt-blown fibrous web layer is bonded thereto, and then the flow-conducting structure corresponding to the uneven structure is formed together. Therefore, as described above, the present embodiment is a process of forming a non-woven fabric by forming a spun-bonded spun fiber and a melt-blown spun fiber directly on a forming mold 4 for forming a flow-conducting structure. The flow guiding structure corresponding to the molding die is directly formed in the middle. Incidentally, the rib 51 formed on the thin layer 5 mainly S can destroy the surface tension of the fluid when the thin layer is used for a sanitary article, so that the (10) body is broken into smaller water drops and is easy. The flow is diffused to the periphery through the recessed area to achieve the effect of the flow guiding. It is added that the aforementioned molding die 4 is such that the thin layer 5 forms a convex rib, but actually, when the thin layer 5 is adsorbed on the molding die 4 When the rib 51 is formed in addition to 201240651, by adjusting the adsorption strength of the negative pressure unit 6, the thin layer 5 can also be formed into a hole through which the fluid can pass (not shown, in addition, when the spunbonded fiber is melted and melted) When the spun fiber bundle is formed on the molding die 4, if the softness is insufficient to conform to the molding die 4, the spunbond web which is layered on the molding die 4 can be further provided by further providing an additional heater. The layer and the meltblown fiber web layer are further heated to soften it, which helps to bond and conform to the molding die 4. It is further added that the manufacturing method of the embodiment utilizes a spunbonding spinning device 2 at the same time. With a melt-blown spinning device 3, that is, a method of manufacturing the nonwoven fabric Taking the spunbond-meltblown composite process (SM process) as an example, but in other variations, the technology of the present invention can also be applied to the SMS, SMMS composite process or the separate spunbonding and meltblown processes, in short, as long as The spinning fiber is directly formed on the molding die 4 for molding the flow guiding structure to form a flow guiding structure while forming the mesh. For example, as shown in FIG. 5, when applied to a separate melt blowing process. Corresponding to the above steps 11 to 13, the molten polymer raw material is directly melted by the melt-blown spinning device 3, and then the molten polymer raw material is drawn into the melt-blown spinning fiber by hot air drafting, followed by melt-blown spinning. The fibers are then laminated on the forming die 8 into a thin layer 5', and at the same time, the convex ribs corresponding to the ribs 81 of the forming die 8 are formed, that is, the flow guiding structure, and the forming die 8 can also be wound around The drum structure is formed into a drum-shaped cage structure. Alternatively, referring to Fig. 2 and Fig. 6, when applied to a separate spunbonding process, the meltblown spinning device 3 of Fig. 2 is omitted, corresponding to the above steps n to 13, 疋 directly using the spunbond spinning device 2 molten polymer raw material, and then the molten polymer raw material is subjected to cooling drafting to form a spunbonded filament fiber 8 201240651 -, and the spunbonded spun fiber is further laminated on the forming mold 9 into a thin layer 5", and At the same time, the ribs 51" corresponding to the ribs 91 of the molding die 9 are formed. Therefore, as described above, the present invention forms the spun fiber in the layered layer by incorporating the molding of the flow guiding structure into the forming process of the non-woven fabric. At the same time, the flb is formed into a flow guiding structure, and the spun fiber is still in a certain degree of softening state when the layer is formed into a net, and at the same time, the flow guiding structure is formed, compared with the past. The method can shorten the length of the entire production line and shorten the time course of the non-woven fabric being processed and transported, so that the effect of saving the process and reducing the cost can be achieved. However, the above description is only a preferred embodiment of the present invention. The scope of the present invention is not limited by the scope of the invention, and the equivalent equivalents and modifications of the present invention are still within the scope of the present invention.
