2. Description of the Related Art In recent years, electric vacuum cleaners using disposable dust collection bags have become widely used due to their ease of dust disposal and their ability to capture fine dust. Conventionally, filter paper for dust collecting bags used in this type of vacuum cleaner includes wood pulp, hemp pulp, glass fiber, synthetic or regenerated fiber of normal denier (1 denier (d) or more) and a small amount of PVA binder fiber. Is used.

The filter paper for such a dust bag expands the structure that is easily clogged with flat wood pulp or hemp pulp by blending synthetic or regenerated fibers of 1 d or more to collect efficiency (dust collection rate) and pressure loss. (Air permeability) and balance,
Furthermore, the hemp pulp and the PVA-based binder fiber are blended to impart strength to the paper.

However, such filter bags for dust collecting bags have a large fineness of wood pulp, hemp pulp, synthetic or regenerated fibers to be used, and the flatness of the wood pulp and the hemp pulp is small despite the small number of constituents. Although the collection efficiency is good due to the effect, there is a drawback that the pressure loss is large.

Further, it is important that the disposable dust collecting bag is inexpensive, but there is a problem in that it is expensive because a large amount of synthetic or recycled fiber is used to expand the clogging structure of wood pulp and hemp pulp. This type of vacuum cleaner contributes to the slow spread of the vacuum cleaner while providing a comfortable environment and convenience.

Means for Solving the Problems As a result of intensive studies to achieve the above object, the present inventor has blended a mercerized wood pulp and an ultrafine denier synthetic or recycled fiber in a specific ratio and By setting the packing density (volume of fiber content per unit volume) within a specific range, it is possible to balance the dust collection rate and air permeability. Furthermore, the use of heat-fusible composite fibers reduces air permeability. The present invention has been completed to find that strength can be imparted without inviting.

According to the filter paper for the dust collecting bag of the present invention as described above, the following operational effects (1) to (4) can be obtained. (1) Wood pulp (eg NBKP and mercerized NBK
Since it is mainly based on P), it is inexpensive. (2) Since the fineness is small, the number of fibers per unit weight is large, and by using fine denier synthetic or regenerated fibers with a small diameter and by using mercerized wood pulp, the clogging structure of the wood pulp is appropriately expanded. In addition, the small mesh having a large number of three-dimensional structures formed between the fibers or pulp and the mercerized wood valp enhances the capturing power of fine dust and the initial pressure loss is small. (3) Since the heat-fusible composite fiber effectively adheres to the intersection of the synthetic or regenerated fiber and the pulp, it has high strength and high air permeability. (4) By setting the fiber packing density within a specific range, the ability to capture fine dust is high.

In the present invention, wood pulp, mercerized wood pulp, synthetic or regenerated fibers of fine denier, and heat-fusible composite fibers are blended in a specific ratio, and the basis weight and the fiber packing density are adjusted to specific ranges. It is essential to achieve the intended purpose, but the thickness and blending amount of fine or fine denier synthetic or regenerated fiber and the blending amount of mercerized wood pulp are the most important points.

The fineness of fine denier synthetic or regenerated fibers is less than 1d, preferably about 0.5d. 1
If it is more than d, the ability to capture fine dust is significantly reduced. In addition, the amount of synthetic or recycled fiber of this fine denier is 5
20% (% by weight, the same applies hereinafter). If it is less than 5%, the effect does not appear because the number of fine denier synthetic or regenerated fibers decreases. On the other hand, if it exceeds 20%, it should be possible to obtain a filter paper for a dust bag having a high collection efficiency and a small pressure loss, but the fine denier synthesis or the amount of regenerated fiber is too large and uneven texture is formed. It is not preferable because it causes a large variation in filtration performance, which lowers the commercial value, and is also expensive. A fiber having a fiber length of 1 to 6 mm, preferably 3 to 5 mm can be used.

The dust collection rate is JI at a flow velocity of 0.2 m / sec.
Using 4 types of test dust specified by S-Z8901, diameter 0.
It was calculated by the following formula from the number of dusts at the sample inlet and the number of dusts at the sample outlet that passed the sample when the dust of 3 μm to 10 μm was generated and passed through the sample. Dust collection rate (%) = (1−A / B) × 100 A: sample outlet dust number B: sample inlet dust number
