[0002]

2. Description of the Related Art In general, mesh fiber materials are excellent in breathability, stretchability, fit and lightness, and are frequently used in sports clothing, fashion clothing, underwear and the like. However, the conventional mesh fiber materials mainly focus on air permeability, and there has been almost no study on UV cut performance, and at present there is no mesh fiber material excellent in UV cut performance. is there.

[0003] On the other hand, exposure of the skin or the like under direct sunlight in summer or the like causes skin roughness and inflammation of the skin due to ultraviolet rays or the like. As a countermeasure, usually, a parasol, a hat, summer clothing, or the like is used. Clothes etc. are used so as not to expose the skin. In addition, when fishing, climbing, camping, gardening, sports, farming, and the like in the field, in order to protect themselves from pests such as mosquitoes and bees, clothing such as insect repellent clothing is worn as a countermeasure.

[0004] However, when clothes are applied so as not to expose the skin due to the measures against ultraviolet rays and insect repellent, sweating from the skin not only causes stuffiness and discomfort but also causes sunstroke under the scorching sun in summer. Yes, and there is no problem with the breathability of clothing made of a mesh fiber material, but as described above, there is a problem that skin may be roughened by ultraviolet rays and skin irritation may occur, and clothing cannot be worn for a long time. . In particular, in recent years, due to the decrease in the ozone layer protecting the earth, the amount of ultraviolet rays falling on the earth has increased, and the emergence of clothing having excellent ultraviolet ray cutting performance has been desired.

[0005]

[0007]

Embodiments of the present invention will be described below in detail. The mesh fibrous material of the present invention is a fibrous material to which a metal adhesion layer is adhered by a sputtering process, and a hole having a maximum linear distance of 0.3 to 10 mm is formed in the fibrous material. Is from 5 to 100 pieces / cm ² .

[0008] The mesh fiber material in the present invention is a knitted fabric,
Any of a woven fabric and a non-woven fabric may be used. For example, in the case of a knitted fabric, a tricot knitted fabric, a Russell knitted fabric, a circular knitted eyelet knitted fabric, and the like can form a mesh knitted fabric. Also,
In the case of a woven fabric, a mesh woven fabric can be formed if the warp and the weft have a thread removal structure in which a certain interval is removed.
In the case of a nonwoven fabric, a mesh nonwoven fabric can be formed by punching after forming a nonwoven fabric by a spunbond method, a spunlace method, or the like. Examples of the fibers used in the mesh fiber material of the present invention include synthetic fibers such as polyester fibers, polyacrylic fibers, and polyamide fibers, and natural fibers such as cotton, silk fibers, and hemp, or glass fibers, carbon fibers, and aramid fibers. Special organic fibers, which may be used alone or in combination with two or more.
A mixture of more than one species can be used.

The mesh shape (hole shape) of the mesh fiber material of the present invention is not particularly limited, and may be a polygon such as a circle, an ellipse, a square, a rectangle, a rhombus, or a triangle. The size of the mesh in this mesh fiber material is such that a hole having a maximum linear distance of 0.3 to 10 mm (a hole having a hole diameter of a maximum linear distance of 0.3 to 10 mm) is formed and the number of holes is 5 １００100 / cm ² is required. In the present invention, the size of the mesh refers to the size of the pores of the mesh fiber material after the formation of the metal adhesion layer. The maximum linear distance is the diameter in the case of a circle, the long axis in the case of an ellipse, the vertical line (height) from the base to the long angle in the case of a triangle, the case of a polygon such as a square, a rectangle, and a rhombus. Refers to the length of the diagonal.

[0010] If the hole has a maximum linear distance of less than 0.3 mm, the air permeability deteriorates and the usability (moistiness / discomfort, ease of use) is deteriorated, which is not preferable.
If the pore size exceeds the above range, it is not preferable because the ultraviolet ray blocking performance and the insect repelling performance cannot be exhibited. If the number of the holes is less than 5 / cm ² , the air permeability becomes poor, and the usability (moistiness / discomfort, ease of use) is deteriorated.
If it exceeds 0 / cm ² , it is not possible to exhibit the ultraviolet ray blocking performance, which is not preferable. The mesh preferably has a maximum linear distance of 0.3 to 3.0 mm, more preferably a maximum linear distance of 0.5 to 1.5 mm, and the number of holes is 10 to 10 mm. The number is preferably 100 / cm ² , more preferably 30 to 90 / cm ² . In the present invention, the maximum linear distance of the mesh (holes) in the mesh fiber material is set to 0.3 to 10 mm, and the number of the holes is set to 5 to 100 / cm ² . Since small insects such as mosquitoes and vines cannot penetrate through each hole of the mesh fiber material, excellent insect repellency can be exhibited.

In the present invention, a method for producing a mesh fiber material to which a metal adhesion layer is adhered by a sputtering treatment includes a method in which a metal adhesion layer is adhered to a previously prepared mesh fiber material by a sputtering treatment and a method in which a metal adhesion layer is adhered. There is a case where a mesh fiber material (a knitted fabric, a woven fabric, a nonwoven fabric) is produced using a fiber or a nonwoven fabric. However, from the viewpoint of efficiency and the like, a metal adhesion layer is attached to a mesh fiber material produced in advance by a sputtering process. The case is preferred. In the present invention, the sputtering treatment means a target material in a vacuumed sputtering apparatus, for example, stainless steel, titanium, copper, which is to be attached to a fibrous material.
A high-density plasma discharge is created by using electric and magnetic fields near metals such as nickel and silver, and inert gas ions such as ionized argon gas and xenon gas are accelerated by the electric field and collide with the target. By the energy, the target material is knocked out in the form of molecules or atoms,
Refers to a process of attaching to a fibrous material such as cloth. The kinetic energy is extremely high as compared with conventional vapor deposition, electroplating, and chemical plating, and adheres to textiles such as cloth as ultrafine particles (in Angstroms).

[0012] As a specific method of attaching a metal adhesion layer to a fiber material by a sputtering process, for example, a vertical low-temperature high-rate sputtering device (manufactured by Tokuda Seisakusho, model number CAF-36PV) can be used. . In this sputtering apparatus, a cylindrical target (cathode) and a rod-like anode made of metal for sputtering are provided vertically in a sealable casing, and a long knitted fabric, a woven fabric, etc. are provided behind the anode when viewed from the anode. The feed shaft and the take-up shaft of the fibrous material are provided vertically, respectively. First, the inside of the casing is depressurized, and then
Argon gas is introduced into the casing, a low-pressure argon gas atmosphere of about 10 ^-4 to 10 ^-5 Torr is applied to the casing, and a DC voltage of 500 to 1000 V is applied between the anode and the cathode. The long fiber material is sent out at a constant temperature so that the surface faces the anode, wound on a winding shaft, and the cations dissociated from the argon gas are accelerated to collide with the cathode target, and the cathode surface Metal, for example, stainless steel, and the metal is scattered and adhered to the long fibrous material.

The metal as the target is not particularly limited as long as it has a UV-cutting property and is a metal or alloy capable of being sputtered. For example, stainless steel, titanium, aluminum, tin, zinc, copper, copper Alloy (C
u-Ag-based alloy, Cu-Zn-based alloy, Cu-Sn-based alloy, Cu-Al-based alloy, Cu-Ni-based alloy, etc.), nickel, silver, cobalt, chromium, niobium and other simple metals, stainless steel, Cobat alloys, metal oxides,
At least one metal selected from metal nitrides and the like are included. In particular, from the viewpoint of further improving the ultraviolet cut performance and the like, which is the object of the present invention, stainless steel, titanium,
It is desirable to use copper or copper alloy metal. By using these metals, a metal attachment layer can be attached to the fibrous material. In addition, when a metal nitride such as titanium nitride is deposited, it can be deposited by adding nitrogen gas to the argon gas, and when a metal oxide such as titanium oxide is deposited, it can be deposited on the argon gas. It can be attached by adding oxygen gas.

Further, a single layer or a plurality of layers of two or more layers can be attached to the metal layer by the above-mentioned sputtering process. For example, a metal adhesion layer made of stainless steel excellent in ultraviolet ray cutting performance can be attached to the first layer, and a metal adhesion layer made of copper excellent in antibacterial properties and deodorant properties can be attached to the second layer. By attaching two or more metal adhesion layers, the insect repellent performance and the ultraviolet cut performance, which are the objects of the present invention, can be further improved, and further other performance can be added. Further, the front and back surfaces of the mesh fiber material are made of two kinds of metal layers, for example, a metal adhesion layer made of stainless steel having excellent ultraviolet cut performance on the front surface side of the mesh fiber material, and copper having excellent antibacterial properties and deodorant properties on the back surface. A metal adhesion layer can also be applied.

[0015] The thickness of the metal adhesion layer should be 50 to 10000 angstroms, preferably 100 to 5000 angstroms, and more preferably 300 to 3000 angstroms. If the thickness of the metal adhesion layer is less than 50 angstroms, the ultraviolet ray cut performance cannot be improved, and if it exceeds 10,000 angstroms, the ultraviolet ray cut performance does not change, but it becomes uneconomical and the usability decreases. Is not preferred.
The thickness of the metal adhesion layer can be adjusted by adjusting the gas pressure in the casing of the sputtering apparatus, the voltage between both electrodes, the current, the sputtering time (the feed rate of the fibrous material), and the like. As an aspect of the adhesion of the metal adhesion layer, the ultraviolet light-cutting performance can be exhibited by attaching the metal adhesion layer to the front and back surfaces or the front surface (the surface on the side exposed to sunlight including ultraviolet rays) of the fibrous material. .

According to the present invention having the above-described structure, a fibrous material to which a metal adhesion layer is adhered by a sputtering process, preferably, a metal made of stainless steel, titanium, copper, or a copper alloy is adhered with a thickness of 50 to 10000 angstroms. Holes having a maximum linear distance of 0.3 to 10 mm are formed in the fiber material, and the number of the holes is 5 to 100 / cm ^2.
By doing so, a mesh fiber material having excellent breathability, ultraviolet cut performance, and insect repellency is provided, and in the present invention, the ultraviolet ray shielding rate can be 60% or more, and the above-mentioned usability is impaired. By adjusting the maximum linear distance of the holes and the number of holes in a range that does not exist, the ultraviolet ray shielding rate can be made 70% or more. The mesh fiber material of the present invention is subjected to the above-mentioned sputtering treatment, and by specifying the physical properties of the mesh of the mesh fiber material, the first time the air permeability is secured, the mesh fiber material having excellent ultraviolet cut performance and insect repellent performance is obtained. Is provided, if not forming the metal adhesion layer deviating from the scope of the present invention,
Or, if the maximum linear distance of the holes is out of the range of the present invention, or if the number of holes is out of the range of the present invention,
In any case, the effect of the present invention cannot be obtained.

The mesh fiber material to which the metal adhesion layer is adhered by the sputtering process of the present invention can maintain the texture of the fabric as it is, can be washed with water and can be dry-cleaned, and has the above-mentioned moisture permeability and air permeability inherent to the fiber. It is not affected by the sputtering process, and can provide a metallic luster and hue as never before. In addition, when the metal used in the sputtering process is attached to the metal adhesion layer with stainless steel, the salt water resistance, moisture resistance, alkali resistance, sweat resistance, and weather resistance are good, together with the physical properties of the mesh, the ultraviolet ray cut performance, Insect repellency can be further improved.

Further, when visually recognizing the object through the mesh fiber material of the present invention, in order to improve the visibility,
Each metal adhesion layer may be adhered by the above-described method or the like using a mesh fiber material having a dark color such as black. Thereby, the brightness of the fibers constituting the mesh fiber material is further reduced by the shielding effect of the metal adhesion layer, and when visually viewed through the mesh fiber material with the naked eye, the reflected light from the surface of the mesh fiber material is significantly weakened. The visibility is the same as when viewed through transparent glass, and vice versa,
Due to the presence of the metal adhesion layer, the reflected light becomes strong, so that the viewer cannot see it. In addition, a substance having an insect repellent and repellent effect, for example, N, N-diethyl-m-toluamide, a pyrimidine derivative, a piperidine derivative, a xanthate derivative, is added to the mesh fiber material to which the metal attachment layer is attached by the sputtering treatment of the present invention. At least one selected from insect repellents and repellents extracted from alcohols, esters, and natural products (animals and plants) may be coated on the metal-adhered layer to further improve insect repellent performance. .
