It was necessary to prepare a variety of ferrules that matched the manufacturing width, or to be prepared for loss due to convergence cant.Furthermore, as the width was increased, the difficulty of achieving uniformity increased exponentially, making it difficult to achieve uniformity in actual production. In order to obtain a wide range of good quality non-woven fabrics, highly sophisticated technology has always been required.

That is, the present invention provides a method for producing a nonwoven fabric using a melt blowing spinneret having a series of numerous spinning orifices and gas ejection slits arranged adjacent to the orifices. While the collection net surface moves in the same direction as the width of the spinneret (the direction in which the spinning orifices are arranged) by a distance equal to the width of the spinneret, the entire conveyor net is traversed in the direction perpendicular to the width of the spinneret an integral number of times, one or more reciprocations. Continuously collects fiber flow while
This is a method for producing a nonwoven fabric, which is characterized by laminating layers.

The thermoplastic resin heated and melted is supplied in a fixed amount to the spinneret 2 via a gear pump, and is continuously spun from a series of numerous spinning orifices built into the spinneret 2. Further, a high speed spinneret is disposed in the spinneret 2, and the spun yarn from the spinning orifice is pulled and thinned by the high speed airflow ejected from the gas jet 4) to form a fiber stream 4. This fiber stream 4 is then transferred to a conveyor belt having a suction device and in which the collection net surface moves in a direction perpendicular to the fiber stream 4 and the entire conveyor net 5 traverses in a direction perpendicular to the direction of movement of the 27 points. A nonwoven fabric 6 of fibers is collected and laminated on the throat 5.
becomes. This nonwoven fabric 6 is sequentially taken off from the conveyor net by a take-up near roll 7 and wound up by a take-up roll 8. At this time, the movement of the net surface is carried out by the drive motor 12, and the traverse movement of the entire conveyor net is carried out by the drive motor 11, which can each be changed in speed separately.
本発明の第１のポイントは、コンベアネットのネット面
の移動方向を紡糸オリフィスの配列方向と同一方向とし
、且つコンベアネット全体を紡糸オリフィスの配列方向
に対し直角方向にトラバースさせる点にある。従来の方
法ではネット面の移動力向は紡糸オリフィスの配列方向
に対し直角方向であるため、それ故製品幅は口金幅によ
って決定されるものであったが、本発明の方法を採用す
ることにより、製品幅を自由に設定できることが可能と
なるのである。すなわちコンベアネット５のトラバース
幅はりミツトスイッチ９ １０の位置を変えることによ
り容易に変更しうるちのであり、従って口金幅のせまい
ものであっても広幅化が容易に可能となるのである。The first point of the present invention is that the moving direction of the net surface of the conveyor net is the same as the direction in which the spinning orifices are arranged, and the entire conveyor net is traversed in a direction perpendicular to the direction in which the spinning orifices are arranged. In the conventional method, the direction of the moving force of the net surface was perpendicular to the direction in which the spinning orifices were arranged, so the product width was determined by the width of the spinneret, but by adopting the method of the present invention, This makes it possible to freely set the product width. That is, the traverse width of the conveyor net 5 can be easily changed by changing the positions of the beam limit switches 9 and 10, and therefore even a narrow mouth can be easily widened.
本発明の第２のポイントはコンベアネットのネット面が
口金幅の距＃ｌｌ学中中だけ移動する間ムこコンベアネ

となる。また、トラバースが１往復未満の場合は第３図
の如きジグザグ状となり製品価値は無くなってしまい、
このことからも１往復以上トラバースさせることは重要
である。トラバースの往復回数は特に限定されるもので
はないが、目付の均一性と生産性から１〜４往復とする
のが好ましくより好ましくは１〜２往復である。The second point of the present invention is that the entire conveyor net is traversed an integral number of times, equal to or more than one round trip, while the net surface of the conveyor net moves only a distance equal to the mouth width. This means that the number of layers in the product can be adjusted as desired. In other words, the distance M of the base width is 77.
If the entire 7 knots are moved back and forth 2n times during the movement, a product with one layer stacked in a V-shape as shown in Figure 2 will be obtained. However, if the number of reciprocations is not an integral number, the product will not have a uniform V-shaped lamination but will have an uneven number of laminations. In addition, if the traverse is less than one round trip, it will become a zigzag shape as shown in Figure 3, and the product value will be lost.
From this point of view, it is important to traverse more than one round trip. The number of reciprocations of the traverse is not particularly limited, but from the viewpoint of uniformity of basis weight and productivity, it is preferably 1 to 4 reciprocations, and more preferably 1 to 2 reciprocations.

ので好ましい。- By arranging the spinning orifices in a trapezoidal or chevron-shaped distribution, with the central part flat and gradually expanding thinly toward both ears, the overlapping part is rectangular. This is preferable because it is possible to obtain a nonwoven fabric that has extremely smooth overlapping rather than stepwise overlapping.
その結果、目付や強力の均一性に優れた不織布となるの
である。The result is a nonwoven fabric with excellent uniformity in basis weight and strength.

Alternatively, if the fibers constituting the nonwoven fabric have weak adhesion properties to each other, it is preferable to provide a suction device).
It is important to select the optimum conditions depending on the resin used and the product application. The nonwoven fabric obtained by the method of the present invention can be used as it is, but if the adhesiveness is relatively weak depending on the resin used, it is preferable to perform bonding or entangling treatment to improve physical properties and uniformity. Namely, high-speed fluid processing, needle punch processing, fusion processing,
Adhesion treatment etc. are applied depending on the purpose.

である。In the manufacturing method of the present invention, the spinning machine with a narrow spinneret width can be used to widen the width, so there is less loss when changing types (change of fabric weight, product width, resin, etc.), and it is advantageous for accommodating a large number of products. Furthermore, the method for producing a nonwoven fabric of the present invention can be applied to the production of various nonwoven fabrics such as the spunbond method and the Franche spinning method.
