の製法を提案した。As a cartridge filter for filtering fine particles in a liquid, the present inventors have proposed a cartridge filter in which nonwoven fabrics having different average fiber diameters and average pore diameters previously manufactured by a melt blow method or a jet spinning method are wound and laminated, and a manufacturing method thereof. Proposed.
前記のカートリッジフィルターは粒子捕捉効率が高く流
体の濾過抵抗が低く濾過寿命も長くクリーン性に富んで
いるのが特徴であるが、多品種の不織布濾材を巻込むた
め加工が繁雑であり、不織布濾材自体の強度も製法上他
のスパンボンド不織布と比較して強度が弱く、巻込時に
濾材が破損、切断しやすい等の問題点があり加工コスト
を押上げ、カートリッジフィルターが、高価格になり市
場競争力が低くなり種々のユースポイントで広範に使用
されるまでには至らなかった。The above-mentioned cartridge filter is characterized by high particle capture efficiency, low fluid filtration resistance, long filtration life, and excellent cleanliness, but it is complicated to process because it contains many types of non-woven filter media. The strength of itself is weak compared to other spunbonded non-woven fabrics due to the manufacturing method, and there are problems that the filter medium is damaged and easily cut when rolled up, which pushes up the processing cost and makes the cartridge filter expensive and the market It became less competitive and could not be widely used at various points of use.

巻状に巻回す際に予め不織布に目の粗いネットを片側に
あて、ネットと共に巻込むことにより本考案を完成させ
た。The present inventors did not reduce the performance of the nonwoven fabric-laminating laminated cartridge filter having excellent performance, but rather improved the performance while lowering the processing cost.
As a result of intensive research to supply an inexpensive and high-performance cartridge filter to the market, when winding multiple layers of non-woven fabric into a tubular winding, a coarse net is pre-applied to one side of the non-woven fabric and wound with the net. The present invention was completed by putting it in.
メルトブロー方式又はジェット紡糸方式で作られた平均
繊維径0.5〜５０μｍ、平均見かけ密度0.03〜0.2g／cm3
を有し、筒の外側になる程、平均繊維径、平均孔径が大

ートリッジフィルターにおいては、これらの不織布を多
孔性コアに巻込む際に、不織布のみを単独で巻込む場
合、これらの不織布は他の製法のスパンボンド不織布に
比較して強度が弱く巻取り時の張力の変動により不織布
が破損、切断しやすく歩留が悪かった。Average fiber diameter made by melt blow method or jet spinning method 0.5 to 50 μm, average apparent density 0.03 to 0.2 g / cm 3
In a cartridge filter formed by winding a non-woven fabric in which the average fiber diameter and the average pore diameter increase toward the outer side of the cylinder in a multi-layered tubular winding, when winding these non-woven fabrics into the porous core, In addition, when only the non-woven fabric was wound alone, these non-woven fabrics were weak in strength as compared with other spun-bonded non-woven fabrics, and the non-woven fabric was easily broken or cut due to fluctuations in tension during winding, resulting in poor yield.
そこで本考案者らは、不織布を巻込む際、目の粗いネッ

持体として張力をかけ巻込みながら、その支持体である
ネット上に平均繊維径、平均孔径の異なる不織布を供給
しつつ、不織布自体には張力を一切かけずに巻き込むこ
とにより、不織布の巻込時の破損、切断を皆無にして歩
留を向上させる事が出来た。Therefore, when the non-woven fabric is wound, the present inventors apply a coarse net to one side of the non-woven fabric and wind it together, that is, to apply tension to the porous core continuously with the coarse net as a support. While winding, while supplying non-woven fabrics with different average fiber diameters and average pore sizes on the net that is the support, by winding without applying any tension to the non-woven fabric itself, damage and cutting at the time of winding the non-woven fabric can be prevented. I was able to improve the yield without any.

を懸けない点である。FIG. 2 shows an embodiment of a manufacturing apparatus for a non-woven fabric wound laminated cartridge filter of the present invention, in which the porous core 1 is fixed to a shaft which works in conjunction with a winding motor 6,
The net 3 and the non-woven fabric filter medium 4 supplied from the non-woven fabric supply device 5 are involved in the winding operation. The feature of this device is that the net 3 is wound as a support, so that no tension is applied to the filter medium.

る事が判った。According to the present invention, the non-woven fabric wound laminated cartridge filter according to the present invention enables a purposeful flow rate to be obtained in the filtration of the viscous liquid, as compared with the case where only the nonwoven fabric is wound and laminated. It was found that the filtration life of the viscous liquid was also improved.

Among polypropylene non-woven fabrics produced by the melt-blowing method within the range of 0.13 g / cm 3 , five types of non-woven fabrics A to E having different average fiber diameters and average pore diameters are located outside the cylinder, A filter medium having a large average pore size was wound around each four rounds together with a polypropylene net, and a total of 0.8 m 2 of the five types was wound to produce a cartridge filter. Table 1 shows the fiber diameter and pore diameter of the five types of filter media. In addition, as a comparative example, a cartridge filter was produced by similarly winding five kinds of filter media without using a net. Table 2 shows the measurement results of the viscous liquid penetration resistance. The measurement results of the filtration life of the viscous liquid are shown in FIG.
