Detailed Description
In the following description, for purposes of explanation, numerous implementation details are set forth in order to provide a thorough understanding of the various embodiments of the present disclosure. It should be understood, however, that these implementation details are not to be interpreted as limiting the disclosure. That is, in some embodiments of the disclosure, these implementation details are not necessary, and thus should not be used to limit the disclosure. In addition, for the sake of simplicity, some conventional structures and elements are shown in the drawings in a simple schematic manner. In addition, the dimensions of the various elements in the drawings are not necessarily to scale, for the convenience of the reader.
The present disclosure provides a method for manufacturing a three-dimensional nonwoven fabric, which is performed by a textile apparatus having a roller device. Through the rotation of the roller device, partial melt-blown fibers can be dragged by the roller device before reaching the collecting device, so that the manufactured three-dimensional non-woven fabric has certain thickness and good bulkiness.
Fig. 1 shows a schematic side view of a textile apparatus 100 according to an embodiment of the present disclosure. The textile apparatus 100 includes a meltblowing device 110, a collecting device 120, and a roller device 130. The meltblowing apparatus 110 is configured to eject meltblown fibers F. In some embodiments, the meltblowing apparatus 110 has at least one exit orifice 112 and the meltblown fibers F are ejected from the exit orifice 112. The collecting device 120 is configured to collect the meltblown fibers F sprayed by the meltblowing device 110. In some embodiments, the collecting device 120 has a receiving net 122 and a conveying element 124, and the receiving net 122 is disposed on the surface of the conveying element 124 to receive the meltblown fibers F without interruption by being carried by the conveying element 124. Specifically, the conveying element 124 can be, for example, a combination of a conveying roller and a conveying belt. In some embodiments, the collection device 120 has an aspiration element 126 disposed on the other side of the conveying element 124 relative to the receiving web 122 to provide suction to direct the meltblown fibers F to the receiving web 122. The roller device 130 is disposed between the meltblown device 110 and the collecting device 120, and is configured to receive a portion of the meltblown fibers F and rotate to enable the received meltblown fibers F to reach the collecting device 120.
Fig. 2 shows a schematic side view of the weaving apparatus 100 of fig. 1, wherein the direction of the viewing angle of fig. 2 is perpendicular to the direction of the viewing angle of fig. 1. In some embodiments, the meltblowing apparatus 110 has a plurality of orifices 112, and the plurality of orifices 112 are arranged in a direction parallel to the direction of elongation of the roller apparatus 130. In some embodiments, the collecting device 120 can support the roller device 130 through the connecting element 140, and the connecting element 140 can electrically connect the collecting device 120 and the roller device 130, and further electrically connect to a central system (not shown) such as a computer, so as to transmit the moving condition of the receiving net 122 and the rotating condition of the roller device 130 to the central system in real time for proper regulation and control.
Fig. 3 illustrates a flow chart for manufacturing a stereoscopic non-woven fabric using the weaving apparatus 100 of fig. 1. The method for manufacturing the three-dimensional non-woven fabric includes steps S10, S20, S30 and S40. In step S10, the meltblown fibers are sprayed with a meltblowing apparatus. In step S20, a first portion of the meltblown fibers is received with a roller arrangement. In step S30, a second portion of the meltblown fibers is received with a collecting device. In step S40, the first portion of the meltblown fibers is caused to reach a collection device by rotation of the roller device. In the following description, the above steps will be further explained.
Referring to fig. 1 and 3, in step S10, the textile apparatus 100 ejects the meltblown fibers F through the discharge holes 112 of the meltblowing device 110. In some embodiments, the meltblown fibers F have a single orifice discharge rate between 0.01 g/min and 0.50 g/min. In some embodiments, when the meltblowing apparatus 110 has a plurality of orifices 112, the density of the orifices 112 is between 35 and 65 orifices/inch. With the above arrangement, the meltblown apparatus 110 can discharge a certain weight of meltblown fibers F per unit time, so that the resulting three-dimensional nonwoven fabric 200 has a proper basis weight (weight).
In some embodiments, the meltblowing apparatus 110 jets the meltblown fibers F perpendicular to a receiving surface of the collection apparatus 120, where the receiving surface is the surface of the receiving web 122 facing the spit-out orifice 112. In this way, when the receiving surface is parallel to the ground, the meltblown fibers F can easily fall onto the collecting device 120 and the roller device 130 between the meltblown device 110 and the collecting device 120 due to the effect of gravity. In some embodiments, the meltblown fibers F in the formed dimensional nonwoven 200 have a diameter between 0.2 microns and 20 microns. In some embodiments, the material of the meltblown fibers F includes polyolefin, polyester, polyurethane, nylon, or a combination of any of the above. By selecting appropriate materials, the three-dimensional nonwoven fabric 200 can be made to have a corresponding purpose. For example, if polyolefin is used, the resulting three-dimensional nonwoven fabric 200 can be used as a sound absorbing and noise reducing material; if polyester is used, the resulting three-dimensional nonwoven fabric 200 can be used as a thermal insulation material.
In step S20, the textile apparatus 100 receives the first portion F1 of the meltblown fibers F with the roller device 130. Next, in step S30, the weaving apparatus 100 receives the second portion F2 of the meltblown fibers F with the collecting device 120. In detail, since the roller device 130 is located between the meltblown device 110 and the collecting device 120, and the roller device 130 and the meltblown device 110 only partially overlap, after the meltblown device 110 sprays the meltblown fibers F, the first portion F1 of the meltblown fibers F reaches the roller device 130 first, and the second portion F2 of the meltblown fibers F directly reaches the receiving web 122 of the collecting device 120.
In step S40, after the first portion F1 of the meltblown fibers F reaches the roller device 130, the first portion F1 of the meltblown fibers F is rotated by the roller device 130 to reach the collecting device 120. Then, the first portion F1 of the meltblown fibers F that reaches the collecting device 120 is moved by the rotation of the roller device 130 between the roller device 130 and the collecting device 120, and passes between the roller device 130 and the collecting device 120. Meanwhile, after the second portion F2 of the meltblown fibers F reaches the collecting device 120, the second portion F2 of the meltblown fibers F is transported by the transporting element 124 of the collecting device 120, moves between the roller device 130 and the collecting device 120, and passes between the roller device 130 and the collecting device 120. In other words, the meltblown fibers F are integrally formed between the roller device 130 and the collecting device 120 by the rotation of the roller device 130 and the transportation of the collecting device 120, thereby forming the three-dimensional nonwoven fabric 200.
In some embodiments, when the roller device 130 rotates, a tangential direction of a side of the roller device 130 adjacent to the collecting device 120 is the same as a conveying direction of the receiving surface of the collecting device 120. Therefore, each melt-blown fiber F between the roller device 130 and the collecting device 120 can move towards the same direction, so that the formed three-dimensional non-woven fabric 200 has a neat and stable structure, and the melt-blown fibers F in the three-dimensional non-woven fabric 200 can have a meniscus structure with the same direction. The meltblown fibers F having the meniscus structure may serve as air chambers therebetween to contain air, thereby increasing the bulkiness of the three-dimensional nonwoven fabric 200.
In some embodiments, the receiving web 122 of the collection device 120 moves at a rate of between 1 meter/minute and 5 meters/minute. By adjusting the moving speed of the receiving net 122 of the collecting device 120 in the above-mentioned suitable range, the formed three-dimensional nonwoven fabric 200 can have a better thickness H. In detail, if the moving speed of the receiving web 122 is too high, the receiving web 122 can receive too few meltblown fibers F in a unit area, so that the formed three-dimensional nonwoven fabric 200 is too thin; if the moving speed of the receiving web 122 is too small, the receiving web 122 can receive too many meltblown fibers F per unit area, so that the resulting three-dimensional nonwoven fabric 200 is too thick. In addition, if the moving speed of the receiving web 122 is too high, the formed three-dimensional nonwoven fabric 200 cannot form a highly entangled fiber web due to the insufficient amount of the meltblown fibers F, thereby affecting the structural stability of the three-dimensional nonwoven fabric 200.
In some embodiments, the vertical distance L between the roller device 130 and the collection device 120 is between 10 mm and 100 mm. By adjusting the vertical distance L between the roller device 130 and the collecting device 120 within the above-mentioned suitable range, the formed three-dimensional nonwoven fabric 200 can also have a better thickness H. Specifically, the vertical distance L between the roller device 130 and the collecting device 120 determines the thickness of the stacked meltblown fibers F passing therethrough, and thus may affect the thickness H of the resulting three-dimensional nonwoven fabric 200. In some embodiments, the thickness H of the dimensional nonwoven fabric 200 is between 0.5 mm and 100 mm.
In some embodiments, the three-dimensional non-woven fabric 200 has good bulkiness due to the mutual matching between the base fabric weight of the three-dimensional non-woven fabric 200 and the thickness H of the three-dimensional non-woven fabric 200. As described above, since the basis weight of the three-dimensional nonwoven fabric 200 is related to the single-hole discharge rate of the meltblown fibers F, and the thickness H of the three-dimensional nonwoven fabric 200 is related to the moving rate of the receiving web 122 and the vertical distance L between the roller device 130 and the collecting device 120, the bulkiness of the three-dimensional nonwoven fabric 200 can be improved by adjusting the single-hole discharge rate of the meltblown fibers F, the moving rate of the receiving web 122, and the vertical distance L between the roller device 130 and the collecting device 120 within a suitable range. In some embodiments, the base fabric weight of the dimensional nonwoven fabric 200 is between 25 grams per square meter and 550 grams per square meter. In some embodiments, the loft of the dimensional nonwoven fabric 200 is between 150 cubic inches/ounce and 600 cubic inches/ounce.
In the following description, the three-dimensional nonwoven fabric of examples 1 to 6 and comparative example 1 of the present disclosure will be further described. The stereoscopic non-woven fabric of each example was manufactured by performing steps S10 to S40, and the comparative example was manufactured in a known step through a known twin-roll weaving apparatus. The detailed descriptions of the examples and comparative examples are shown in table one.
Watch 1
Next, the three-dimensional nonwoven fabrics of examples 1 to 6 and comparative example 1 of the present disclosure were subjected to measurements of the base fabric weight, thickness, bulk, compression recovery, horizontal tensile strength, and horizontal peel strength to further verify the efficacy of the present disclosure, and the test results are shown in table two below.
Watch two
As can be seen from table two, the three-dimensional nonwoven fabrics of examples 1 to 6 have larger base fabric weight, thickness and better bulkiness than those of comparative example 1 after the same time of manufacture. In addition, the three-dimensional nonwoven fabrics of examples 1 to 6 have good compression recovery, i.e., the three-dimensional nonwoven fabrics have good elasticity. In addition, the three-dimensional nonwoven fabrics of examples 1 to 6 have certain horizontal tensile strength and horizontal peel strength, that is, the three-dimensional nonwoven fabrics have a stable structure.
According to the above embodiment of the disclosure, the spinning device enables the first part of the melt-blown fiber to reach the collecting device through the rotation of the roller device and pass between the roller device and the collecting device together with the second part of the melt-blown fiber, so as to form the three-dimensional non-woven fabric. The moving speed of the receiving net of the collecting device, the single-hole discharge rate of the melt-blown fibers and the vertical distance between the roller device and the collecting device are adjusted in a proper range, so that the formed three-dimensional non-woven fabric has certain thickness and good bulkiness.
Although the present disclosure has been described with reference to particular embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present disclosure, and therefore the scope of the present disclosure should be limited only by the terms of the appended claims.
