A synthetic fiber centering on denier is used, and this is entangled with a needle punch or the like to be molded. This manufacturing method is a dry nonwoven fabric manufacturing method, but in the case of this method, the dispersibility is poor even if fine fibers (for example, 0.1 denier) are used,
Unable to obtain uniform product quality. Further, since the needle holes of the needle punch are left, there is a limit to the production of the filter material for bag filter by the dry nonwoven fabric production method.

For example, tea bags (Japanese Patent Laid-Open No. 59-228100), filters for household vacuum cleaners (Japanese Patent Laid-Open No. 5-7714), and the like are known. These are papers made from ultrafine fibers by a wet papermaking method. In the filter medium by this method, a large number of minute holes can be formed, and excellent dust collection efficiency can be obtained.

て再生させる。The bag filter filter material 1 of this embodiment is used for collecting gas such as exhaust gas from various factories by filtering gas such as exhaust gas. The bag filter filter material 1 is periodically backwashed because the collected dust particles are accumulated on the surface of the bag filter material 1 as time passes and the resistance increases. That is, a gas is blown against the bag filter filter medium 1 in the direction opposite to the normal passage direction to cause the gas to flow backward, so that the collected dust adhering to the surface of the bag filter filter medium 1 is removed and regenerated.

The following glass fibers are mixed with a fiber binder to form the filtration layer 2. For example, 3 μm of fine synthetic fibers and 0.5 μm of glass fibers are molded together with a fiber binder for bonding by a wet papermaking method. The outer surface (the surface on the side that collects dust) of the filtration layer 2 is smoothed by a hot roll to improve the peelability of the attached dust.

れらを接着する。The strength maintaining layer 3 is made of felt or woven cloth having excellent strength. The adhesive layer 4 is made of an adhesive fiber or an adhesive. In the case of the adhesive fiber, the adhesive fiber is adhered to the filtration layer 2 and the strength maintaining layer 3 by being caught by the adhesive fiber. In the case of an adhesive, the filter layer 2 and the strength maintaining layer 3 are bonded to each other while maintaining sufficient air permeability.

できる。[Function] Since fine synthetic fibers (5 μm or less), glass fibers (1 μm or less) and fiber binders have different diameters, when they are usually mixed, the whole tends to be non-uniform. Since the filtration layer 2 is manufactured by a wet papermaking method, three kinds of fibers having different diameters can be uniformly dispersed and mixed in water. As a result, uniform fine holes can be formed on the entire surface of the filtration layer 2, the pressure loss is low, the air can be smoothly flowed, and the dust in the air can be efficiently collected.

This makes it possible to withstand repeated backwashing work, prolong the life of the bag filter filter medium 1, and minimize the deterioration of the filtering function over time.
【００２３】湿式抄紙法により、性能及び品質の安定し

Was made of felt or woven fabric having excellent strength, but it may be manufactured by a wet papermaking method using synthetic fibers larger than the filtration layer 2. In this case, the filtration layer 2 can be manufactured by a series of paper making machine lines, the manufacturing process can be significantly reduced, and the manufacturing cost can be reduced.

Good. For example, the strength maintaining layer 3 is manufactured in advance by making paper using coarse fibers having a large diameter. Next, ultrafine fibers may be made into paper on the strength maintaining layer 3 to produce the filtration layer 2, and the filtration layer 2 and the strength maintaining layer 3 may be joined by paper making.
