Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to surface-treated fabrics, and more particularly to fabrics with a noble metal glossy surface such as gold or silver, and a method for producing the same.

<Problems to be solved by the invention> Spacesuits worn during extraspace activities, trips to the moon, etc. are required to be completely airtight and insulated. On the other hand, there are stuffed animal-like clothes that imitate spacesuits, but they have poor breathability and are painful to wear for long periods of time.

An object of the present invention is to provide a fabric that has a precious metal luster appearance reminiscent of a spacesuit or an alien, and has breathability similar to ordinary fabrics.

Another object of the present invention is to provide a manufacturing method that allows fabrics having such a special glossy surface to be mass-produced at low cost.

<Means for Solving the Problems> The fabric having a special glossy surface of the present invention has Ti, TiN, Cr, CrN, Aj! .

It is characterized in that a thin film layer containing a metal or an intermetallic compound selected from the group of Au, Ag, and CuO and having a thickness of 0.05 μm to 0.8 μm is formed.

Further, the fabric manufacturing method of the present invention uses a sputtering device that is equipped with a supply roll and a take-up roll for the fabric to be surface-treated and has a locus facing a target, and the fabric is continuously transferred from the supply roll to the take-up roll. The method is characterized in that a predetermined metal or intermetallic compound is sputtered from the above-mentioned cuget while moving it selectively or intermittently.

In the present invention, the thickness of the thin film layer is 0.05 μm to 0.05 μm.
The reason why it is set to 8 μm is that when it is less than 0.05 μm, good metallic luster cannot be achieved and the fabric is transparent.
This is because if the thickness exceeds 0.8 μm, the original flexibility of the fabric will be lost.

<Example> The drawing shows a sputtering apparatus used for carrying out the method of the invention.

A vacuum chamber 1 has a front door that can be opened and closed, and a fabric supply roll 2, a take-up roll 3, and a chain conveyor 4 installed along an arcuate guide inside the chamber.
Along the outer periphery of the chamber, there are a heater 5 for preheating the fabric, a Honhart Mentoror for cleaning the fabric surface by spraying particles onto the fabric, a first Kuget 7, and a second target. 8 are arranged in sequence.

The chamber is provided with an exhaust path 10 connected to a vacuum exhaust system via a main valve 9, and the chamber can be evacuated to 1X10 Torr. Further, a gas introduction device 11 is provided so that A gas and N2 gas can be introduced into the chamber at a desired mixing ratio and a desired pressure.

A power supply device 13 drives targets 7 and 8 to
- Generates a superimposed electric field of a DC electric field and a high-frequency electric field in the vicinity.

When using such a device, first, chamber 1
Open the door, set a washed cloth, for example a strip of 150 cm wide and 50 m long, wound around a roll core, on the supply roll shaft, and pass the tip of the strip of cloth through the surface of the arc-shaped conveyor 4. Connect to the take-up roll 3. Close the door of chamber 1 and operate the exhaust system to reduce the inside of the chamber to IX 10-'Torr or 5X10 Torr.
Make a vacuum.

Thereafter, a mixed gas of Ar gas and N2 gas is introduced to 6×1 O Torr using the gas introduction device]1. heater 5,
Bombardment 6, first and second targets 7.
8 to operate the chain conveyor 4 and the winding device. When the untreated fabric passes in front of the heater 5, it is preheated, and when it passes through the bombardment 6, deposits are knocked out and the fabric surface is cleaned.

While the fabric passes near the target 7.8, the metal or intermetallic compound particles set on the target are spattered from the Kuget surface by collisions of ion particles accelerated by the electric field, and strongly adhere to the fabric surface. . In this way, a thin film layer of a predetermined thickness is formed during the time the fabric passes through the target 7.8. The fabric whose surface treatment has been completed is wound onto a winding roll 3. When all the fabrics have been processed, the power supply is cut off, the gas supply is stopped, and
After the main valve 9 is closed to admit atmospheric air, the chamber door is opened and the treated fabric roll is removed.

Example data shows that in an atmosphere where Ar gas and N2 gas at a mixing ratio of 1:1 was introduced to 6X10 Torr, the distance between the target and the fabric was 15 mm, the target material was Ti, and the power input to the target was 5 W. /c11. When the surface of the fabric was treated under the conditions that the effective length of the cugett on the l orbit was 60cm and the fabric conveyance speed was 40cm/min, a golden shining fabric was coated with a TiN thin film with a thickness of 0.1μm on the front side. was gotten.

Experiments were conducted under the same sputtering conditions with only the type of Cougett material and atmospheric gas changed, and the following examples were obtained. In other words, T1 target and A gas are silver, Cr target and Ar gas are silver, AN target and A are silver, Cu target and Ar gas.
Reddish copper color when using gas, silver when using Ag target and A gas, gold when using ALL target and Ar gas, and silver when using a mixed gas of Cr target, N2 gas, and Ar gas at a mixing ratio of 1:1. Ta.

Further, different materials can be used for the first target 7 and the second target 8, and for example, the following example was obtained. In other words, by setting the first target with Ti and the second target with C, and changing the input power ratio of the first and second targets in a mixed gas atmosphere of N2 and Ar, a golden color was obtained. A neutral color gloss with different nuances ranging from silver to silver was obtained.In addition, the first target was T.
i. When AN was set as the second target and the input power ratio of the first and second targets was varied in an Ar gas atmosphere, a silvery luster with different brightness and light reflectance was obtained.

Furthermore, after forming a Ti layer on the entire surface in the first step, the fabric was once rewound onto the supply roll, and in the second step, N2 gas was introduced to form an rtN layer. A product with strong peeling force was obtained.

The fabric having a special glossy surface of the present invention can be produced not only by the above-mentioned sputtering but also by vapor deposition and ion blasting.

<Effects of the Invention> According to the present invention, it is possible to obtain a fabric with metallic luster such as golden yellow or silvery white without losing breathability and flexibility, and to make clothes with a beauty that has not been seen before. I can do it. In addition, because it reflects heat rays and has an excellent flame retardant rating of 1-1, it is suitable for firefighter and car racers' clothing and disaster prevention curtains, and because of its good heat retention properties, it is suitable for linings for ski wear and cold-weather clothing. Furthermore, it has the effect of not fading, not wearing out, and not being stained easily.
