Regarding how to wear it .

[0002]

2. Description of the Related Art In general, it is necessary to prevent dust from the inside of this dust-free garment from leaking outside through a collar or cuff. For this reason, as shown in Japanese Utility Model Application Laid-Open No. 56-23613, a conventional dust-free garment has a technique of integrally connecting the upper body and the lower body to reduce dust leakage points. As a further deterrent, as disclosed in Japanese Utility Model Laid-Open Publication No. 2-42019, there is a technique in which a hat and socks are combined with the above-mentioned dust-free garment to be integrated.

In this dust-free garment, as shown in the front view of FIG. 2, an upper body covering part 1 and a lower body covering part 2 are joined by a joint 3, and an outer sleeve 5 is attached to the upper body covering part 1. In order to attach and detach this dust-free garment, the chest of the upper body covering portion 1 can be opened and closed with a fastener 4.

[0004] The sleeve of the dust-free garment is generally single-layered, and has a squeezing structure so that the ends of the sleeve fit tightly in order to make it difficult for the dust inside the dust-free garment to leak outside.
As a method of making this squeezing, the end of the sleeve is folded into a bag shape and sewn, and a flat rubber is passed through the bag portion of the sleeve end, and an elastic knitted fabric is directly sewn to the end of the sleeve There is a way.

In addition, gloves are worn on dust-free clothing used in the semiconductor device manufacturing process in order to prevent dust from being generated from hands. When wearing this glove, put the mouth of the glove inside the cuff of the dust-free garment and cover the mouth of the glove with the sleeve of the dust-free garment to prevent dust from coming from inside the glove. Used to wear.

[0006]

In the above-described conventional dust-free garment, the mouth portion of the glove to be used must pass through a palm larger than the wrist, so that the glove is worn larger than the size of the wrist. In the situation, there is excess cloth on the wrist. If this part is covered with the cuffs of a dust-free garment, the surplus part of the fabric will fold inside the cuffs, the folds of the umbrella will be gaps, and the dust in the dust-free garments will easily escape from this gap to the outside Leak. Therefore, in the conventional sleeve structure of a dust-free garment, there is a problem that dust leakage from the sleeve cannot be sufficiently suppressed.

In order to prevent the dust from leaking, a large part of the hand (a part where the size of the glove is not so different from the size of the wrist) may be covered with a cuff of a dust-free garment. The cuffs naturally move to the narrow part of the wrist,
The aforementioned problems arise.

It is an object of the present invention to provide a dust-free garment capable of preventing both dust from a human body and dust from a wrist leaking from a cuff and a method for wearing the same.

[0009]

According to the present invention, there is provided a dust-free garment having a first cuff formed to be in close contact with a wrist to prevent dust from being emitted from the wrist, and a first cuff outside the first cuff. It has a second cuff for inserting gloves and preventing dust from coming from the gloves.
And changing the squeezing degree of each cuff of the inner sleeve and the outer sleeve,
Tighten the degree of squeezing of the inner sleeve cuffs and squeeze the outer sleeve cuffs
It is characterized by a reduced degree .

In addition, the degree of expansion and contraction of the cuffs of the inner sleeve is ± 1 cm.
The outer sleeve cuffs have a degree of elasticity of ± 3 cm, and the squeezed portions of the inner sleeve and the outer sleeve cuffs are made of flat rubber or stretch knit fabric. It can be made of fiber or resin.

[0011] Further, the structure of the present invention is designed so that the wrist is in close contact with the wrist.
The first cuff to prevent dust from coming from inside this wrist
Insert gloves on the inside sleeve and outside of the first cuff.
Outer sleeves with second cuffs to prevent dust from gloves
And changing the squeezing degree of each cuff of the inner sleeve and the outer sleeve,
Tightening the inner sleeve cuffs, the outer sleeve cuffs
In the method of wearing a dust-free garment, the lower body covering portion of the dust-free garment is worn , the inner sleeve and the outer sleeve are passed through, the glove is worn outside the hand, The hem is placed between the outer sleeve and the inner sleeve via the end of the outer sleeve, and the end of the outer sleeve is attached to the wrist, and the hem of the glove does not fold in a pleated shape. It is characterized in that the outer cuff is brought into close contact with the wrist at the part.

According to the structure of the present invention, by attaching the inner sleeve to the sleeve of the conventional dust-free garment, it is possible to prevent the dust from the upper arm and the body from the wrist from leaking to the outside. Outside)
The sleeve can prevent dust from hands and gloves from leaking to the outside. In addition, by changing the squeezing degree of the inner sleeve and the outer sleeve, that is, by tightening the squeezing degree of the inner sleeve and loosening the squeezing degree of the outer sleeve, the inner sleeve collects dust in the dust-free garment sufficiently, The dust leakage prevention performance can be sufficiently maintained, and the clearance required for attaching and detaching the gloves on the outer sleeve can be sufficiently secured to facilitate the attachment and detachment.

[0013]

Embodiments of the present invention will now be described with reference to the drawings. 1A and 1B are a front view of a dust-free garment according to an embodiment of the present invention and an enlarged front view of a sleeve portion thereof. In the present embodiment, the upper body covering portion 1 and the lower body covering portion 2 are joined by the joint portion 3, but this is achieved by covering the human body with a low-dust-generating cloth, and It prevents dust from clothes from leaking to the outside. An outer sleeve 5 is attached to the upper body covering portion 1, and the upper body covering portion 1
The chest can be opened and closed with a fastener 4, so that a dust-free garment with an integrated upper and lower body can be easily attached and detached.

Here, the structure of the sleeve portion, which is a feature of the present invention, will be described. The outer sleeve 5 is a sleeve part in the upper body covering part 1. Further, by attaching the inner sleeve 8 to the outer sleeve 5 via the stitching portion 6 to form a double sleeve structure, dust inside the dust-free garment is collected by the inner sleeve 8 and its narrowed portion 9. .

As shown in FIG. 1B, a glove 12 is attached to the outside of the hand 11 and the skirt of the glove 12 is housed in the internal space 10 through the end 7 of the sleeve. And the squeezing part 9 of the sleeve
The sleeve 7 is positioned just below the palm of the wrist, so that the cuff is located at the narrow part of the wrist, so that the cuff of the glove 12 does not fold in a pleated shape. Can be in close contact with the wrist. Further, the inside of the outer sleeve 5 has the inner narrowed portion 9 and the skirt of the glove 12, and these serve as stoppers, so that the narrowed portion 7 of the outer sleeve 5 is formed.
Is not displaced.

In this embodiment, the outer sleeve 5 and the inner sleeve 8 are
The upper body covering part 1 and the lower body covering part 2 are made of low dusting material. In order to minimize the gap between the sleeve and the wrist at the end 9 of the inner sleeve 8 so that the sleeve 9 can be in close contact with the wrist, the inner diameter of the sleeve needs to be about ± 1 cm with respect to the wrist, Since the end 7 of the outer sleeve 5 needs to store the hem of the glove 12, the degree of squeezing is made smaller than that of the inner sleeve 8, but the degree of expansion and contraction is about ± 3 cm with respect to the wrist so that there is no excessive room. The degree of expansion and contraction.

In order to obtain such a degree of stretch, flat rubber or stretch knit fabric is used for the squeezed portions 7 and 9 at the sleeve ends. At that time, the flat rubber is used by folding the squeezed portions 7 and 9 into a bag shape and sewing the squeezed portion, and then passing the squeezed portion through the bag portion. The stretchable knitted fabric is directly sewn to the drawn portions 7, 9 at the sleeve ends. The material of the flat rubber and the elastic knit fabric is made of low-dusting synthetic fiber or resin, and the width of the flat rubber and the elastic knit fabric does not impair the feeling of wearing, and the degree of adhesion to the wrist. 2 to 5 cm is desirable so as to increase the

Further, the distance between the inner sleeve end 9 and the outer sleeve end 7 is 3
The size is preferably about 5 cm, in order to reduce the space 10 between the outer sleeve 5 and the inner sleeve 8 within a range where it is not difficult to wear the gloves 12. By reducing the space 10, the exposure of the wrist is reduced, dust from hands and gloves is less likely to collect, and an extra space for collecting dust is eliminated.

[0019]

As described above, according to the structure of the present invention, the sleeve structure has a double structure of an inner sleeve and an outer sleeve, the inner sleeve suppresses dust generation from the body, and the outer sleeve forms hands and gloves. Since the dust from the inside is prevented from leaking out of the clothes, there is an effect that the leak of the dust from the inside to the outside of the sleeve can be suppressed.
