CUS03-P060005-TW M296260 External light produces consumable hyperoxia, and the sterilization method of coating cells to hinder bad bacteria breathing) is more important. At present, in the silver-containing bacteriostatic textiles disclosed in the prior art, the early series directly woven the fine silver thread into the fabric, which is not only costly, but also has a bacteriostatic fabric made of hard, in addition, The ultra-fine metal yarn is easy to cut, which not only causes inconvenience in washing, but is more likely to cause harm to the user. Recently, silver-containing bacteriostatic textiles are mainly prepared by diluting nano silver particles in a solvent, and then attaching nano silver particles to textiles by surface treatment by dip dyeing, spraying, printing or coating. On the yarn. The antimicrobial yarn having nano silver particles disclosed in Japanese Patent Publication No. 244522 first forms a nano silver solution, which is then immersed in the nano silver solution and dried. In addition, as disclosed in Japanese Patent Publication No. 200536987, the nano silver-spun product is sprayed directly onto the textile by spraying a solution of nano silver particles by means of a spray gun. On the top, a nano-silver-containing product is obtained through a drying step. The surface treatment method of attaching nano silver particles to textiles or yarns by dip dyeing, spraying, printing and coating, because the density of nano silver particles contained in the silver film layer coated by solvent dilution is not high, The bacteriostatic effect and long-term effect are easily affected, and the requirements for commercialization functions cannot be met. Due to problems such as batch production capacity, the commercialization speed is slow and the market cannot be used in large quantities. In order to solve the above problems, there is a need to provide a new bacteriostatic textile with nano silver to overcome the disadvantages of the prior art.

6 CUS03-P060005-TW M296260 [New content] The main purpose of this creation is to provide a non-woven fabric made of nano silver material and its application product, which has a high density of nano silver film to achieve better antibacterial ability. . Another object of the present invention is to provide a non-woven fabric made of nano silver material and an application product thereof, which has a nano-silver film with high adhesion to prevent nano silver particles from being washed and washed after being washed. , antibacterial ability to achieve durability and durability. In order to achieve the above object, the non-woven fabric produced by the nano silver material disclosed in the present invention comprises a non-woven substrate comprising at least two surfaces; and a nano silver film covering at least one of the non-woven fabrics. surface. According to one aspect of the present invention, the nano silver film is deposited on one side surface of the non-woven fabric by vacuum sputtering, and the nano silver film is composed of at least one layer of silver particles having a particle diameter of 1 to 5 nm. Stacked, the film thickness is 1~100 nm. In order to make the above-mentioned other objects, features, and advantages of the present invention more comprehensible, the following detailed description of the preferred embodiments and the accompanying drawings are set forth below.

7 CUS03-P060005-TW M296260 Please refer to the figure below for a non-woven side view made of the nano silver material of this creation. The non-woven fabric 1 according to the present invention comprises a non-woven substrate 11 () which comprises at least t surface nano silver _ 12G, at least covering the surface of the non-μ substrate (10) 111. Wherein, the nano silver film tantalum can be used for the (9) J resistance addition and subtraction iron method, = grab evaporation method, hetero (four) physical (four) H, the nano silver particles 121 1 to the side or the two side surfaces (1) of the non-woven substrate 11G, The nano-silver is adhered to the surface m of the non-woven substrate, and the nano-silver particles (2) are tightly combined by the surface characteristics of the material of the non-ferrous substrate U0: a:: one straight one 12. . Preferably, the non-woven fabric is formed in a vacuum chamber to deposit silver atoms on the silver substrate on at least the surface (1) of the nonwoven substrate 11Q. Among them, the conditions of the vacuum money are: base layer relative (four) (four) (four) speed 2m / mm real work monthly to medium gas flow rate 10~200c.c. / min, the ratio of the predetermined power to (4) surface area G 5 ~ Μ wW, the base layer The distance between the materials is 40~200 mm, and the gas pressure in the vacuum chamber is 3~(4).3, so that the particle size of the silver particles + 121 emitted by the crucible is controlled at the scale of (4) nanometer to form a surface of the non-woven substrate 1U. The total thickness is a silver film 120 of (10) nm. Preferably, the particle size of the nematic silver particles 121 emitted by the employee is 1 to 5 nm. 'Because the nano silver film (3) at this scale can release the silver ions more effectively, the non-woven fabric (10) and The system has a stronger antibacterial ability. The particle size and the stack thickness of the nano-silver particles 121 which are plated on the surface of the non-woven substrate 111 can be adjusted according to the actual non-woven fabric which is required to be bacteriostatically treated, and are not limited to the scales of the above embodiments.

8 CUS03-P060005-TW M296260 For example, but not limited to, the non-woven fabric made of the nano silver material of this creation is used in the fields of food, clothing, housing, travel, etc. for medical purposes, household use, clothing use, etc. Products that wish to be bacteriostatically treated.
