Description

  The present invention relates to an undergarment or a fiber or cloth used in contact with the skin, an undergarment used in contact with the undergarment or skin, or an accessory used in contact with the skin, and a method of manufacturing an undergarment or fiber for use in contact with the skin or a fabric. In addition, the present invention relates to a method for manufacturing an undergarment or an accessory used in contact with the skin.

  It has been known for a long time that when a piece of germanium or germanium powder is kept in contact with the skin, far-infrared radiation is emitted, and a certain health promotion effect and healing effect can be obtained. For this reason, it has been practiced to sew socks, supporters and the like using a cloth in which germanium powder is printed in a pattern on the back with an adhesive or the like, or germanium powder is mixed.

Also, when the winter air dries, the human body becomes charged due to friction with clothes, touching a grounded metal, etc., causing pain due to discharge, or touching electronic components in this state destroys the circuit. Therefore, it is necessary to remove the charge frequently, and in particular, in work where static charging is a problem, it is practiced to wear clothing using a fabric woven with conductive fibers.

  If germanium powder is printed in a pattern on the back with an adhesive, etc., the soft texture, flexibility, hygroscopicity, etc. of the underwear will be lost, so the comfort of the underwear will be very bad and it will not look good. There was a problem of becoming.

  In addition, in order to appropriately express the effect of contact with germanium, it is necessary to widen the contact area of germanium with the skin, but widening the print area of germanium makes the comfort worse. As a result, there was a problem that sufficient effects could not be obtained.

  Moreover, when it was made to contain in a fiber with a powder form, there existed a problem that germanium would fall out by washing etc. and an effect was not continued.

  Furthermore, in order to give a garment an effect of removing static electricity, a garment in which conductive fibers are woven is not comfortable to wear. In particular, when used in underwear, there is a problem that the texture and moisture absorption are poor.

  The inventors of the present invention have intensively studied to solve such conventional problems, and by attaching germanium to fibers or fabrics by vacuum deposition or sputtering, the texture as an undergarment is hardly impaired and uniform and easy. It was found that a fiber or fabric for skin wearing with germanium adhered thereto was obtained.

The present invention has been made based on such knowledge.
That is, the first embodiment of the fabric accessory fiber or fabric used in contact with the undergarment or the skin is formed by uniformly adhering 0.2 to 2 gr / m ^{2 of} germanium ultrafine particles on the surface of the fiber or fabric. It is a feature.

  The amount of deposition of the germanium ultrafine particles corresponds to 20 to 200 nm when converted to an average film thickness when deposited as a thin film on a flat plate (hereinafter the same).

  Examples of the fibers used in the present invention include cotton yarn, wool, silk yarn, various chemical fibers, and blended products thereof. Examples of the fabric include these woven fabrics, nonwoven fabrics, and stretch fabrics.

In the present invention, the amount of germanium particles deposited is set to 0.2 to 2 gr / m ^{2. If the} amount deposited is less than 0.2 gr / m ² , the effect of the present invention cannot be obtained sufficiently, and 2 gr / m ² This is because the texture and hygroscopicity of the fibers and fabrics are impaired when the temperature exceeds.

  In the first invention, the above-described germanium ultrafine particles are coated on the entire surface of these fibers and fabrics, or a part thereof.

  The fiber or cloth for jewelry that is coated with the ultrafine germanium particles is used as a material for producing various kinds of known underwear and accessories used in contact with the skin.

  Examples of the underwear to which this invention can be applied include shirts, pants, tights, socks, bras and the like, and examples of accessories used in contact with the skin include supporters such as headbands, knees, elbows, ankles and wrists. The

  Embodiments of the present invention will be described below.

  SSN22096 collar type regular type 100% cotton men's shirt for men made by Marianne Co., Ltd. Electron beam heating vapor deposition experiment machine (Iwazaki Electric Co., Ltd. Model: EC250 / 15 / 1L) was used to deposit metal germanium. As the metal germanium, a 99.9% germanium piece was used, and the film formation conditions were as follows: degree of vacuum: 6 mPa, film formation rate: 0.6 nm / sec, film formation time: 180 sec, 75 sec, 290 sec.

The obtained germanium ultrafine particle-coated fabric had a light brown color. The following table shows the germanium film thickness and adhesion amount in this example. The average film thickness was measured by the following method. That is, first, germanium is vapor-deposited on the glass substrate under the same conditions as the above-described film formation conditions, with a film formation time of 10 to 400 seconds. A standard calibration curve is created by measuring a germanium-deposited substrate with a fluorescent X-ray film thickness meter (SFT9100) manufactured by Seiko Instruments Inc. Next, the film thickness was calculated by comparing the actual vacuum deposition time with the standard calibration curve. Further, the amount of germanium (Ge) attached was measured by measuring the residual amount of 10 × 10 cm □ 50 woven fabrics having respective film thicknesses.
Document No. Deposition time Average film thickness Ge adhesion 1 180 sec 110 nm 0.9 gr / m ²
2 75 sec 45 nm 0.3 gr / m ²
3 290 sec 175 nm 1.1 gr / m ²

From the above table, it can be seen that the film thickness and the germanium adhesion amount are in a substantially linear proportional relationship with the film formation time. In addition, the amount of germanium per unit area (calculated as specific gravity: Ge: 5.32gr / cm ³ (25 ° C)) from the above-mentioned film thickness calculated from the calibration curve is almost the same value as the Ge adhesion amount measured by the ignition residue measurement method. Results were obtained.

  Using Aizu Memo, 4 pieces of cotton fabric with 100% cotton and 37cm x 12m width were joined together, and on one side, an electron beam heating vapor deposition pilot device (Iwasaki Electric Co., Ltd. Model: CB200 / 45/300) was used. In the same manner as in Example 1, germanium was vacuum-deposited under film formation conditions of a vacuum degree: 6 mPa, a film formation rate: 0.6 nm / sec, and a film formation time: 180 sec. The formed film was unfastened at both ends of the second-stage joint portion, and a 12-meter one was taken out and subjected to a washing durability test. Using a fully automatic washing machine MAW-HV8UP manufactured by Mitsubishi Electric Corporation, simulated washing was repeated 10 times using Kao Attack as a detergent, and a metal germanium thin film peeling experiment was conducted.

  The evaluation was performed by visual observation, touch, and a static measurement device (STATIRON-M) manufactured by Sind static. It was confirmed that there was no change in the brown color tone of the sputtering surface, the flexibility as the fabric was maintained, and no charging phenomenon was observed.

  Note that the charging test was performed by measuring the fabric by friction charging 20 times with an electrostatic charging brush manufactured by HORIBA, Ltd. in an atmosphere of a temperature of 26 ° C. and a humidity of 69% RH. As a result of the experiment, the undeposited fabric was charged to about plus (+) 1 kV and had a half-life of 2 seconds, whereas none of the samples deposited with germanium were charged at all.

  Further, a charging test was performed under the same conditions (10 ° C., 30% RH) as those in the winter when it is easy to be charged, but no charging was observed even in the sample with the minimum film thickness of 20 nm.

A metal germanium thin film was formed on the same material as in Example 1 using a sputtering machine (Model CFS-4ES-231 manufactured by Techno Fine Co., Ltd.). As the metal piece, metal germanium with a purity of 99.9% was used, and as the thin film formation conditions, the metal germanium thin film was operated at a vacuum degree: 4 × 10 ⁻³ Pa, an argon flow rate: 25 cm ² / min, and a sputtering power: 100 W. The sputtering time was set so that the film thickness of the film became 20 to 200 nm.

  In the same manner as in Example 1, a cloth made by sputtering 5 sheets of 100% cotton for men and a metal germanium thin film was used using a fully automatic washing machine MAW-HV8UP manufactured by Mitsubishi Electric, and Kao Attack (registered trademark) as a detergent. Using this method, a simulated washing was repeated 10 times to perform a metal germanium thin film peeling experiment. The evaluation was performed by visual observation, touch, and a static measurement device (STATIRON-M) manufactured by Sind static. It was confirmed that there was no change in the brown color tone of the sputtering surface, the flexibility as the fabric was maintained, and no charging phenomenon was observed.
