Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a method for manufacturing a powder-adhered sheet body used for clothing and the like to which powder of far-infrared radiation ceramics or the like is adhered. Furthermore, the present invention relates to clothing using this sheet body and a sheet piece that is used by attaching this sheet body to clothing or the like.

BACKGROUND ART Conventionally, powders such as far-infrared emitting ceramics have been attached to clothing. This attachment method usually uses resin to fix the powder onto the cloth. In this method, the resin hardens the powder, making the adhesive part hard and unpleasant to the touch, making it unusable for underwear. In addition, elasticity is also lost.

Therefore, the object of the present invention is to realize clothes that have a soft and pleasant feel and do not lose their elasticity while being coated with powder.

Means and Examples for Solving the Problems The first aspect of the present invention is to have an adhesive adhesion process for adhering the adhesive to the entire surface of the sheet body or to a desired shape, and a powder such as far-infrared emitting ceramics. A flock adhesion process in which the flock made of short fibers and the sheet body that has gone through the above process are charged and the flocs are attached to the sheet body with static electricity, and then a removal process in which the flocs that are not attached to the adhesive are removed using a brush or the like. This is a method for producing a powder-adhered sheet body, which comprises a curing step of curing the adhesive.

This invention will be explained in more detail below.

In the adhesive application step, the adhesive is applied to the front surface of the body surface or only to a portion of the surface to form a desired specific shape. This sheet body may be a cloth or a nonwoven fabric, and may be a long strip-shaped original fabric, or may already be a product such as socks or underwear. Since the adhesive is used to attach the flock later, any adhesive can be used as long as it can maintain a liquid state for a while, and any adhesive used in the production of ordinary velvet can be used as is.

If the adhesive is to be applied to only a part of the surface, screen printing or a method of forming four parts on a roller, inserting the adhesive therein, and pressing the adhesive against the sheet body can be used.

The floc adhesion step is to attach the flocs to each other using static electricity. Specifically, the flocs are placed in a dish-shaped container, sheet bodies are placed on this -L at appropriate intervals, electrode plates are provided on the bottom surface of the container and the top surface of the sheet body, and a high voltage is applied. This interval is approximately several to twenty centimeters, the voltage is approximately tens of thousands to tens of thousands of ports, and the application time is approximately several seconds. The floc used here contains powder, and its manufacturing method will be described later. Various powders can be used depending on the purpose, such as far-infrared emissive ceramics for heat retention, zirconium carbide for heat retention, chitosan or fragrance for antibacterial properties, etc. Deodorizers etc. are used. This powder can be used not only as a single type but also as a mixture of two types. If so, you can lightly rub the surface of the sheet with a brush, spatula, etc., or spray a stream of air.

The curing process is the process of curing the adhesive and fixing the flock to the surface of the sea body.The curing process can be done by simply leaving it to dry, heating it to harden it, or using a curing method depending on the properties of the adhesive. .

In this way, the sheet body to which the powder is attached is completed.

The floc used in this invention contains powder, and its specific structure and manufacturing method may be arbitrary, such as those obtained by mixing the powder into synthetic fibers such as nylon and cutting the mixture into fine pieces. For powders with a relatively short lifespan, such as fragrances and deodorants, which perform relatively functions, the powder may be simply mixed with the floc and stirred to adhere the powder. This attachment method is mechanically weak and the powder is likely to be lost, but this poses no problem if the functional life is short, and since it is simple, it can be used in conjunction with other attachment methods. Furthermore, the material adhered in the following manner is suitable for the present invention because it has a strong adhesion and is particularly flexible.

That is, flocs and powder with a particle size of 10 micrometers or less are placed in water mixed with a surfactant, heated and stirred, and then the flocs are taken out, dried, and loosened to form a powder. It forms a floc that holds .

Next, this method will be explained in detail.

The flock used here can be made of any material such as wool, cotton, nylon, etc. In addition to those manufactured for electrostatic flocking, ordinary fibers and threads are cut into short pieces of 1 mm or less and ground. , those produced by separating the fibers can be used.

The powder used here is desirably fine in order to improve adhesion, and the particle size is preferably 10 micrometers or less.

First, put the floc and powder in step 1 into water mixed with a surfactant, and stir while heating. This surfactant is used to submerge the flock in water and loosen the fibers with the water, and ordinary laundry detergent can be used as is. Heating and stirring are for loosening the fibers of the flock and allowing the powder to penetrate into the fibers and come into contact with the fiber surfaces, and may be performed at 60'C or higher for about 30 minutes to 3 hours. Any method can be used for stirring, and if sufficient time is spent, it is also possible to use only water convection during heating.

In this way, the powder is mechanically entangled with the fibers of the flock and attached, making it unnecessary to use an adhesive. However, an adhesive such as glue that melts at high temperatures and exhibits adhesive strength at low temperatures may also be used and added to the water.

Thereafter, the flocs are taken out and thoroughly dried using hot air, infrared rays, etc., and the moisture content is reduced to about 7% or less. If the moisture content is high, the flocs remain clumped together and cannot be separated into individual pieces.

Thereafter, the floc is passed through a sieve, gauze, etc. to loosen it into powder.

The flocs formed in this way are caused by the powder adhering to the strong
It does not come off even after washing, and the flock itself does not lose its suppleness.

An embodiment of the above invention will be shown below.

First, apply adhesive (liquid polyamide resin) to the roller that has formed the four parts of the desired shape, and use a doctor to scrape it off, leaving the adhesive only on the four parts.Then press this roller against the cotton material to adhere the adhesive. .

Next, this raw fabric is passed through a dish-shaped container containing flock (1220 cm) with the adhesive facing downward, and a voltage of 100,000 ports is applied by placing an electrode plate directly above the fabric and directly below the container. Then, let it pass over the container for 5 seconds to let the flock settle. Note that this flock was formed as described below.

Next, rub the surface of the original fabric with a brush to remove flocs from areas other than those to which the adhesive is attached.

Next, it is passed through a tenter with a total length of 33 meters for about one minute to harden the adhesive. In this tenter, the first 10 meters are pre-dried at 60 to 70'C, and then the temperature is 12
Bake at 0-1300C.

After this, it is passed through a drum iron to remove wrinkles and is completed.

The floc to which the powder is attached, used in the production method described in 1., is formed as follows.

A woolen yarn approximately 1 mm in diameter is cut into lengths of 0.4 mm and ground in a mortar to form a flock.

As the powder, a far-infrared emitting ceramic ("Resonium A" manufactured by Memoto Light Metal Co., Ltd.) C particle size of 3 to 5 micrometers is used.

The floc and powder are placed in water containing laundry detergent (cationic surfactant) in the same manner as when washing, and heated to 80'C for about 2 hours while stirring with a rod.

After this, the flocs are removed by filtering through a cloth, dried using infrared rays at about 70°C for 5 hours, and passed through a sieve (50 mesh) by pressing with a spatula to form a powder.

A second aspect of the invention is a garment characterized by using the sheet body described above.

Of course, if the clothing itself is used as the sheet material described in Section 2, powder-adhered clothing can be obtained, but if raw cloth or other cloth is used, it can be used to form clothing, and powder-adhered clothing can be obtained. is obtained. In this case, in the adhesive application step L, it is necessary to appropriately set the arrangement and shape so that the adhesive is applied to the part of the garment where the powder or flock is to be applied.

The third aspect of the present invention is a powder-attached sheet piece in which an adhesive with a release paper is provided on the sheet body described in 1-1, and can be adhered to a mask, the lower part of the armpit of clothes, etc. with this adhesive.

The sheet body used here can be made of cloth or non-woven fabric,
In particular, those having elasticity are desirable. A powder-adhered sheet is formed, an adhesive with release paper is usually provided on the side to which no flock is adhered, and the sheet is cut into a shape suitable for the part where it will be used.

For example, this powder-attached sheet piece can be attached with powder that has sterilizing and deodorizing functions and can be adhered to a mask, the lower armpit or question area of underwear, the fingertips of socks, etc., or can have heat-insulating and heat-storing functions. The powder is applied to the fingertips of gloves, socks, and shoes.

Therefore, by simply peeling off the release paper and adhering this sheet piece to clothing, etc., powder-adhered clothing or the like can be realized.

Effects of the Invention As mentioned above, in the manufacturing method of the present invention, the floc contains powder such as far-infrared emitting ceramics, and this floc is attached to the sheet body, so the flexibility and softness of the sheet body is improved. It does not get lost, and since the flock is adhered to the surface in a velvet-like manner, it has an extremely good feel and can be used on underwear without any problems.

In particular, when floc is mixed with powder in water and adhered to it, the floc is only mechanically entangled with the powder, so the floc itself does not lose its softness.
The feel of the sheet body to which this is adhered becomes significantly better.

Furthermore, in this invention, if the sheet body is thin, the flocs will penetrate through the sheet body and adhere to it.
When putting flock on underwear etc., it is no longer necessary to take the trouble of turning the front and back sides, and there is also the advantage that attachment can be carried out from the surface.

In addition, the clothing of the present invention has a comfortable feel because the pliability and elasticity of the sheet body are not lost even when powder is attached.

Furthermore, the sheet piece of the present invention allows powder (= J clothing, etc.) to be obtained extremely easily simply by peeling off the release paper and gluing it together.In particular, if the sheet piece has elasticity, It can be used by adhering it to various parts without worrying about it coming off.
