Problems solved by technology

Filtration efficiency, as the most intuitive indicator for evaluating the particle capture effect of filter materials, is obtained from the ratio of the amount of dust captured by the filter material to the amount of dust in the unfiltered air. In the prior art, the particle size is less than 0.1 μm or greater than 0.5 μm The filtration efficiency of μm particles is better, but the dust with a particle size of 0.1-0.3 μm is difficult to filter

Embodiment 1

[0015] The vacuum cleaner filter material involved in the present invention is composed of an inner layer, a filling layer and an outer layer, and the materials used for the inner layer and the outer layer are the same;

[0016] Inner layer or outer layer: It is woven by glass fiber and chitosan quaternary ammonium salt modified cotton fiber in a satin weave. The warp in the satin weave is composed of 3 glass fibers and 2 modified cotton fibers alternately, and the weft is composed of 1 glass fiber and 2 modified cotton fibers alternately;

[0017] Filling layer: Mix 1 part by weight of polylactic acid fiber, 3 parts by weight of carbon nanotubes and 0.12 parts by weight of fluorosilicone oil; apply the mixture to the inner side of the outer layer and bond the inner layer, the quality of the inner layer and the outer layer is the same, The weight of the filling layer is 1.5 times that of the inner layer.

Embodiment 2

[0019] The weight of carbon nanotubes in the filling layer in Example 1 was adjusted to 2.5 parts by weight, and the weight of the filling layer was adjusted to 1.6 times that of the inner layer, and the rest of the composition was the same as that of Example 1.

Abstract

The invention relates to a vacuum cleaner filter material with high filtration efficiency. The filter material comprises an inner layer, an outer layer and a filling layer, wherein the inner layer andthe outer layer are woven by using glass fibers and modified cotton fibers according to a satin weave mode, and the filling layer contains polylactic acid fibers, carbon nano tubes and fluorosiliconeoil. The filter material provided by the invention is mainly used for a household vacuum cleaner, the filtering efficiency of the filter material is high, and in particular, the removal rate of the dust particles with the particle diameter of 0.1-0.3 micron is 99.999% or above.

Description

technical field [0001] The invention belongs to the technical field of dust collection, and in particular relates to a filter material for a vacuum cleaner with high filtering efficiency. Background technique [0002] In order to reduce the burden of housework and liberate people from heavy cleaning work, vacuum cleaners have entered thousands of households as a convenient and efficient cleaning tool. The vacuum cleaner uses electricity as the driving force for the operation of the machine. It generates a vacuum suction by forming a strong air flow, and uses this suction to wash the dust, paper scraps and other garbage in the place to be cleaned into the dust collection bucket through the hose to complete the cleaning process. process. [0003] The most important function of the vacuum cleaner is to filter and collect dust, that is, it can fully intercept dust and dirt, and at the same time allow air to pass through smoothly, and the materials used should have sufficient st...
