Description

Activated carbon non-woven structure containing silver ions

This creation relates to an activated carbon nonwoven fabric, and more particularly to an activated carbon nonwoven structure containing silver ions.

Non-woven fabrics are widely used in various industries because of their good characteristics of breathability, softness, and pressure resistance. In particular, non-woven fabrics are not subjected to the spinning step at the time of manufacture, but are replaced by long and short fibers or by needle rolling. The fibers are made in a staggered manner with each other in the non-woven fabric having pores which are produced by unidirectional fibers. Therefore, since the non-woven fabric has a high porosity and a filter resistance without a high braid, it is very suitable as a filter material for equipment such as an air conditioner.

In order to eliminate the odor in the air when filtering air, activated carbon particles are often added to the non-woven fabric as a filter material, and the odor can be effectively removed by the adsorption of the activated carbon particles. However, non-woven fabrics tend to breed bacteria internally during long-term use, and are prone to respiratory infections and the like. In order to solve the problem of bacterial growth, antibacterial agents are usually added to the non-woven fabric to inhibit the growth of bacteria. However, since a single antibacterial agent acts only on a part of microorganisms, or a microorganism may be resistant to an antibacterial agent, the antibacterial effect cannot be sufficiently exerted.

Therefore, the use of silver ions as a filter material as an antibacterial agent has been developed. For example, the technique described in the Patent Publication No. 201036654 of the Republic of China, because of the positive charge of silver ions, can adsorb on the surface of bacteria and penetrate the cell membrane into the cell body. And it binds to a functional group such as a thio group or a hydrogen group in a protease in a bacteria, and denatures the protease to lose its activity, so that the bacteria cannot be normally metabolized and die, thereby achieving an antibacterial effect. Further, after the bacteria are decomposed and released, the silver ions can be brought into contact with other bacteria to carry out the above process again, and thus have good durability. However, when silver ions are used for non-woven fabrics, silver ions are often not uniformly distributed in the nonwoven fabric due to problems such as agglomeration, and the antibacterial effect and durability are easily affected.

In view of the above-mentioned problems of the prior art, the creator of the present invention contemplates and designs an activated carbon non-woven fabric structure containing silver ions to improve the lack of the prior art, thereby enhancing the industrial use and utilization. Therefore, the object of the present invention is to provide an activated carbon non-woven fabric structure containing silver ions to solve the problem that it is difficult to achieve a good antibacterial effect by conventional non-woven fabrics, and the non-woven fabric has both deodorization by activated carbon particles and silver ions. Antibacterial effect.

Based on the above object, the present invention proposes an activated carbon non-woven fabric structure containing silver ions, comprising: a non-woven fabric layer containing activated carbon particles, silver ions and metal onion particles. Further, activated carbon particles, silver ions, and metal onion particles are uniformly distributed in the nonwoven fabric layer.

Preferably, the non-woven fabric layer may be a needle-punched nonwoven fabric layer or a hot air non-woven fabric layer.

Preferably, the nonwoven layer may be formed of polyester fibers, and the polyester fibers may be formed of polyethylene terephthalate (PET), polypropylene (PP), or a combination thereof.

Preferably, the metal onion particles may have a particle diameter of 0.2 to 0.3 mm.

Preferably, the metal onion particles may be glitter particles or silver onion grains.

Preferably, the silver ion has a particle size of less than 100 nm.

Preferably, the activated carbon particles may have a particle diameter of 0.025 to 0.045 mm.

Preferably, the nonwoven layer may further comprise an adhesive.

Preferably, the nonwoven layer may further contain an antibacterial agent.

As described above, the activated carbon non-woven fabric containing silver ions according to the present invention may have one or more of the following advantages:

(1) In the activated carbon non-woven fabric structure containing silver ions in this creation, the activated carbon particles having adsorption characteristics and the silver ions having interference with the bacterial cell wall can be uniformly distributed in the non-woven fabric layer, so that the non-woven fabric can be both good. Deodorization and antibacterial effect.

(2) The activated carbon non-woven fabric structure containing silver ions of the present invention can impart a metallic luster to the surface of the non-woven fabric by the metal onion in the non-woven fabric layer, thereby improving the appearance and increasing the user's feeling of using the non-woven fabric containing silver ions.

In order to understand the technical characteristics, content and advantages of the creation and the effects that can be achieved by the examiner, the author will use the drawings in detail and explain the following in the form of the examples, and the drawings used therein The subject matter is only for the purpose of illustration and supplementary explanation. It is not necessarily the true proportion and precise configuration after the implementation of the original creation. Therefore, the scope and configuration relationship of the attached drawings should not be interpreted or limited. First described.

The embodiments of the active carbon non-woven fabric containing silver ions according to the present invention will be described below with reference to the related drawings. For ease of understanding, the same elements in the following embodiments are denoted by the same reference numerals.

Please refer to FIG. 1 and FIG. 2 together, which is a schematic diagram of the activated carbon non-woven fabric structure containing silver ions and a schematic view of the first embodiment. In the present embodiment, the activated carbon non-woven fabric structure containing silver ions of the present invention comprises a non-woven fabric layer 100, which is a needle-punched nonwoven fabric layer formed by interlacing polyester fibers 110, which can be used to make polyester fibers by a needle rolling device. The 110s are closely intertwined with each other to increase the density of the web and to enhance the omnidirectionality of the polyester fibers 110 to increase strength. The polyester fiber 110 may have a fiber length of from 15 to 60 mm, preferably from 38 to 52 mm, to enhance the interlacing between the fibers. Here, the polyester fiber 110 may be formed of polyethylene terephthalate (PET), but is not limited thereto, and may be formed of polypropylene (PP) or a polyester in which PET and PP are combined. In addition, in the embodiment, the non-woven fabric layer 100 further includes metal onion particles 120, silver ions and activated carbon particles 130, and the metal onion particles 120, silver ions and activated carbon particles 130 can be automatically stirred and filled at any time. The new solution is uniformly distributed between the polyester fibers 110.

It is worth mentioning that, in this embodiment, the metal onion particles 120 are glitter particles, and therefore may have a golden metallic luster on the surface of the activated carbon non-woven fabric structure, but are not limited thereto, and the metal onion particles 120 are The diameter may be 0.1 to 0.3 mm, preferably 0.2 to 0.3 mm. When the metal onion particles are uniformly distributed on the non-woven fabric layer 100, the surface can have a remarkable metallic luster, but does not affect the structure of the non-woven fabric layer 100. In addition, the activated carbon particles 130 may have a particle diameter of 0.023 to 0.048 mm, preferably 0.025 to 0.045 mm, and the silver ion may have a particle diameter of less than 100 nm to exert a better adsorption effect and an antibacterial effect of silver ions.

Since the activated carbon non-woven fabric structure containing silver ions of the present embodiment is manufactured by needle rolling, the structure density thereof is high, and the activated carbon particles 130 having adsorption characteristics and the interference with the bacterial cell wall can be interfered by the non-woven fabric layer 100. The acting silver ions are evenly distributed therein, so that the non-woven fabric has good deodorizing and antibacterial effects. Further, the metal onion particles 120 can increase the metallic texture of the surface of the non-woven fabric to improve the appearance and increase the real feeling of the user using the non-woven fabric containing silver ions.

Please refer to FIG. 3, which is a schematic view of a second embodiment of the activated carbon non-woven fabric structure containing silver ions. In the present embodiment, the main difference from the first embodiment described above is that the nonwoven fabric layer 100 is formed by using hot air, and the metal onion particles 120 are silver onion particles, and the non-woven fabric layer further contains an adhesive and an antibacterial agent.

In the present embodiment, the nonwoven fabric layer 100 in the activated carbon non-woven fabric structure containing silver ions of the present invention further contains an adhesive and an antibacterial agent in addition to the silver onion particles, the activated carbon particles 130, and the silver ions. Moreover, the non-woven fabric layer 100 of the present embodiment is formed by thermally fusing the polyester fibers 110 to each other to form a hot air non-woven fabric layer, which can utilize a hot air device. When the hot air penetrates the polyester fibers 110, the fiber web is subjected to hot air and The action of the wind pressure causes the surfaces of the polyester fibers 110 to be melted and adhered to each other to form the nonwoven fabric layer 100.

Further, the non-woven fabric layer 100 of the present embodiment may further be provided with an adhesive to assist the adhesion of the polyester fibers 110 to each other, for example, an adhesive such as an ethylene-vinyl acetate copolymer, but is not limited thereto. Further, in order to increase the antibacterial effect of the non-woven fabric layer 100, an antibacterial agent may be further added, thereby increasing the antibacterial ability of the non-woven fabric layer 100 of the present embodiment, wherein the antibacterial agent may be selected from the conventional antibacterial agents in the art. I will not repeat them.

Since the activated carbon non-woven fabric structure containing silver ions of the present embodiment is manufactured by hot air and an adhesive is added to assist the adhesion of the polyester fibers 110 to each other, the structural density is low, and thus the bulkiness and softness are high. . Further, in addition to the advantages of the first embodiment, the activated carbon nonwoven fabric structure of the present embodiment can exert a better antibacterial effect by adding an antibacterial agent.
