Embodiment
Hereinafter embodiment of the present utility model is elaborated.It should be noted that, in the situation that do not conflict, the embodiment in the application and the feature in embodiment be arbitrary combination mutually.
The filter core of the utility model embodiment is hollow tubular body, and filter core comprises at least one deck filtering layer 3 and at least one deck antibiotic layer 4; Antibiotic layer 4 is formed by the non-woven fabrics winding of laminated multi-layer, and the non-woven fabrics of laminated multi-layer comprises at least one deck the first spun-bonded non-woven fabrics and at least one deck melt spraying non-woven fabrics 2, and melt spraying non-woven fabrics 2 contains antiseptic-germicide; Filtering layer 3 is wound around and is formed by the second spun-bonded non-woven fabrics; Mutual heat bonding between each nonwoven layer of filter core, i.e. heat bonding mutually between each non-woven fabrics in antibiotic layer 4, heat bonding mutually between each non-woven fabrics in filtering layer 3, the mutual heat bonding of non-woven fabrics between antibiotic layer 4 and filtering layer 3.
In the process of making, first be wound around the second spun-bonded non-woven fabrics, then continue to be wound around the first spun-bonded non-woven fabrics and the melt spraying non-woven fabrics 2 of laminated multi-layer, then be wound around the second spun-bonded non-woven fabrics, be wound around again the first spun-bonded non-woven fabrics and the melt spraying non-woven fabrics 2 of laminated multi-layer, until reach the required number of plies.In the process that also can make, first be wound around the first spun-bonded non-woven fabrics 1 and the melt spraying non-woven fabrics 2 of laminated multi-layer, then continue to be wound around the second spun-bonded non-woven fabrics, then be wound around the first spun-bonded non-woven fabrics 1 and the melt spraying non-woven fabrics 2 of laminated multi-layer, be wound around the second spun-bonded non-woven fabrics, until reach the required number of plies.As shown in Figure 1, its antibiotic winding process is shown in Fig. 1, for two-layer the first spun-bonded non-woven fabrics 1 and the melt spraying non-woven fabrics 2 stacked, around filter shaft, is wound around.
As shown in Figure 2, in order to obtain better filtration and antibacterial effect, when total number of plies of described filtering layer 3 and antibiotic layer 4 is greater than when two-layer, described filtering layer 3 can be arranged space with described antibiotic layer 4.
Filter core can comprise two filter layers and one deck antibiotic layer, is followed successively by from inside to outside filtering layer 3, antibiotic layer 4 and filtering layer 3.
Filter core can comprise six layers of filtering layer and five layers of antibiotic layer, is followed successively by from inside to outside filtering layer 3, antibiotic layer 4, filtering layer 3, antibiotic layer 4, filtering layer 3, antibiotic layer 4, filtering layer 3, antibiotic layer 4, filtering layer 3, antibiotic layer 4 and filtering layer 3.
The utility model embodiment also provides another kind of filter core, filter core is hollow tubular body, filter core is wound around and is formed by compound nonwoven cloth, mutual heat bonding between two-layer described spun-bonded non-woven fabrics layer, mutual heat bonding between two-layer described melt-blown nonwoven layer of cloth, mutual heat bonding between described spun-bonded non-woven fabrics layer and melt-blown nonwoven layer of cloth, at least one deck spun-bonded non-woven fabrics layer and at least at least one deck in one deck melt spraying non-woven fabrics layer contain antiseptic-germicide, be that one deck or which floor or whole melt-blown nonwoven layer of cloth contain antiseptic-germicide, also can one deck or which floor or all the spun-bonded non-woven fabrics layer contain antiseptic-germicide, also can one deck or which floor or all melt-blown nonwoven layer of cloth and one deck or which floor or all the spun-bonded non-woven fabrics layer contain antiseptic-germicide simultaneously.
Compound nonwoven cloth is three layers of compound nonwoven cloth, and it is followed successively by spun-bonded non-woven fabrics layer, melt-blown nonwoven layer of cloth and spun-bonded non-woven fabrics layer.
The anti-microbial activity of test filter core
(the filter core specification: length is 1m to get above-mentioned filter core, external diameter is 60mm, internal diameter is 25mm), first water filter cartridge flushing, then the experimental water that preparation contains streptococcus aureus (staphylococcus aurues ATCC6538), the content of the streptococcus aureus in experimental water is 2.5 * 10
5cFU/mL injects the 1L experimental water with syringe in filter core, then detects the content of the streptococcus aureus ATCC6538 in water body after filter element filtering, and test shows: filter core degerming rate all can be reached for more than 99.0%, even can reach 99.9%.
The filter core of the utility model embodiment, can hold back bacterium due to filtering layer 3 and antibiotic layer 4, and the sterilant in antibiotic layer 4 can kill bacterium, can remove 99.0% above bacterium in water by holding back with sterilization like this.And compound nonwoven cloth has the effect of holding back bacterium and base sterilization simultaneously, filter core prepared therefrom also has extraordinary anti-microbial property.Because filter core has improved anti-microbial property, therefore can extend the work-ing life of filter core, can reach more than 18 months.
The filter core of the utility model embodiment, spin the starting material of compound nonwoven cloth as filter core owing to adopting melt spraying non-woven fabrics and spun-bonded non-woven fabrics or melting and spraying/glue, therefore the filter core made, the water flow pressure loss is little, can not exert an influence or affect very little flow velocity, and melt spraying non-woven fabrics and spun-bonded non-woven fabrics self cleanliness factor high, without any other additive (as tensio-active agent, white dyes etc.), so filter core can or not produce secondary pollution to water quality.
Because the ultimate compression strength of melt spraying non-woven fabrics or melt-blown nonwoven layer of cloth is low, the utility model embodiment is by being wound with spun-bonded non-woven fabrics or being wound with the compound nonwoven cloth with spun-bonded non-woven fabrics layer, strengthened the ultimate compression strength of filter core, made filter core be not easy to be crushed or to fracture.
The filter core of the utility model embodiment, can be applied to the antibiotic of water body and filter, as tap water, mineral water, food water, and can also for pharmaceutical liquid processing etc., other needs the filtration of antimicrobial treatment.
Although the disclosed embodiment of the utility model as above, the embodiment that described content just adopts for the ease of understanding the utility model, not in order to limit the utility model.Technician under any the utility model in technical field; under the prerequisite that does not break away from the disclosed spirit and scope of the utility model; can do any modification and variation what implement in form and on details; but scope of patent protection of the present utility model, still must be as the criterion with the scope that appending claims was defined.
