Description of the Related Art In recent years, in household vacuum cleaners and commercial vacuum cleaners, a paper pack filter has been installed in a vacuum cleaner so that it can be treated cleanly after collecting dust. When the paper pack filter collects dust and becomes full, the paper pack filter is removed from the vacuum cleaner together with the dust, and is discarded and incinerated or discarded. The paper pack filter, that is, the base paper used for the vacuum cleaner filter must have a certain air permeability so as not to reduce the suction force of dust, while improving the dust collection rate so that fine dust is not allowed to pass through. Therefore, it is also necessary to reduce the porosity of the paper layer, that is, the pore diameter.

In order to maintain the air permeability and the pore size, such a base paper for a vacuum cleaner filter, in addition to wood pulp,
Raw material costs are high because ultrafine polyester fibers, rayon fibers, vinylon fibers, glass fibers, etc. must be used.In addition, inorganic fibers such as glass fibers fall out of the filter and are exhausted indoors with the exhaust of the vacuum cleaner. There is also a problem that it pollutes the indoor environment.

Alternatively, a mixture of these may be mentioned. The content ratio of waste paper in the raw material in the present invention is 5 to 45% by weight, preferably 10 to 30% by weight. If the blending ratio is less than 5% by weight, the advantage of blending waste paper is lost, and it is necessary to blend expensive ultrafine synthetic fibers. If the blending ratio exceeds 45% by weight, the paper strength will decrease.

If the air permeability is less than 0.1 seconds, the predetermined pore diameter cannot be maintained, and the dust collection rate decreases. On the other hand, if the air permeability is greater than 0.40 seconds, the resistance during suction increases.

It is 2.5 kg / cm 2 . Burst strength is 1.5kg / c
If it is smaller than m 2, a bag will be broken during suction. On the other hand, when the burst strength is more than 3.0 kg / cm 2, a large amount of the added chemicals is required, resulting in an increase in cost and a reduction in the disintegration property of the paper.

ことが最良であることが分かった。As described above, the important characteristic of the base paper for vacuum cleaner filter is to enhance the dust collection rate without lowering the suction force.
Therefore, it is necessary to maintain a predetermined breathability. There are air permeability, density, air permeability, pore size, etc. as the characteristic values of the base paper that are used as an index of air permeability, but manage the air permeability that is easy to measure and can be easily controlled during the papermaking process as an index. Turned out to be the best.

However, when newspaper waste paper is blended at 50%, the strength decreases. The disintegration property indicates that the base paper prepared by mixing waste paper can be completely disintegrated.

得ることができる。As can be seen from the above description, in the present invention, an ultrafine synthetic fiber having a diameter of 10 μ or less, which has been used conventionally, is used in order to increase the dust collection rate while maintaining the air permeability. By using waste paper and mixing it with the raw material in a predetermined amount, it is possible to inexpensively obtain a base paper for a vacuum cleaner filter having a performance equal to or higher than the conventional one.

きる。Since the base paper for a vacuum cleaner filter of the present invention has a disintegrating property, it is possible to easily disintegrate, collect, and reuse broke produced in the manufacturing or processing of the base paper, which is economically advantageous. Is extremely large and contributes to the reduction of product cost. Further, in the case of a base paper having no disaggregation property, it is inevitable to disintegrate and collect broke and the like and to cause it to be incinerated or drained into wastewater, resulting in environmental pollution. In the case of the base paper, it is possible to disintegrate and recover the damaged paper and the like, and thus it is possible to prevent such environmental pollution.

心配もない。Further, since the base paper for a vacuum cleaner filter of the present invention does not need to use inorganic fibers such as glass fibers as a raw material, the inorganic fibers fall off during use of the vacuum cleaner and are discharged from the vacuum cleaner together with the exhaust gas. There is no concern about environmental pollution.

合率が４５重量％を超えると紙強度が低下する。The waste paper pulp used in the present invention includes newspaper waste paper, fine paper waste paper , pulp from corrugated cardboard waste paper, and DI.
P (deinking pulp) or a mixture thereof may be mentioned. The content ratio of waste paper pulp in the raw material in the present invention is 5
-45% by weight, preferably 10-30% by weight. If the blending ratio is less than 5% by weight, the advantage of blending waste paper pulp is lost, and it is necessary to blend expensive ultrafine synthetic fibers. If the blending ratio exceeds 45% by weight, the paper strength will decrease.

If the air permeability is less than 0.1 seconds, the predetermined pore diameter cannot be maintained, and the dust collection rate decreases. On the other hand, if the air permeability is greater than 0.40 seconds, the resistance during suction increases.

It is 2.5 kg / cm 2 . Burst strength is 1.5kg / c
If it is smaller than m 2, a bag will be broken during suction. On the other hand, when the burst strength is more than 3.0 kg / cm 2, a large amount of the added chemicals is required, resulting in an increase in cost and a reduction in the disintegration property of the paper.

ことが最良であることが分かった。As described above, the important characteristic of the base paper for vacuum cleaner filter is to enhance the dust collection rate without lowering the suction force.
Therefore, it is necessary to maintain a predetermined breathability. There are air permeability, density, air permeability, pore size, etc. as the characteristic values of the base paper that are used as an index of air permeability, but manage the air permeability that is easy to measure and can be easily controlled during the papermaking process as an index. Turned out to be the best.

る。As can be seen from Table 1, when the amount of newspaper waste pulp is increased, the air permeability is increased and the pore diameter is decreased, which shows the same effect as when the ultrafine synthetic fiber is added. However, when newspaper waste paper pulp is blended at 50%, the strength decreases. The disintegration property indicates that the base paper prepared by blending waste paper pulp can be completely disintegrated.

安価に得ることができる。As can be seen from the above description, in the present invention, an ultrafine synthetic fiber having a diameter of 10 μ or less, which has been used conventionally, is used in order to increase the dust collection rate while maintaining the air permeability. By using waste paper pulp and mixing it with the raw material in a predetermined amount, it is possible to inexpensively obtain a base paper for a vacuum cleaner filter having a performance equal to or higher than that of the conventional one.

きる。Since the base paper for a vacuum cleaner filter of the present invention has a disintegrating property, it is possible to easily disintegrate, collect, and reuse broke produced in the manufacturing or processing of the base paper, which is economically advantageous. Is extremely large and contributes to the reduction of product cost. Further, in the case of a base paper having no disaggregation property, it is inevitable to disintegrate and collect broke and the like and to cause it to be incinerated or drained into wastewater, resulting in environmental pollution. In the case of the base paper, it is possible to disintegrate and recover the damaged paper and the like, and thus it is possible to prevent such environmental pollution.

心配もない。Further, since the base paper for a vacuum cleaner filter of the present invention does not need to use inorganic fibers such as glass fibers as a raw material, the inorganic fibers fall off during use of the vacuum cleaner and are discharged from the vacuum cleaner together with the exhaust gas. There is no concern about environmental pollution.
