DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust-proof garment worn in a clean room, a bio-clean room, etc. for the purpose of preventing static electricity and preventing dust.

[0002]

2. Description of the Related Art When entering a clean room or a bio-clean room for manufacturing semiconductors or the like, dust-proof clothing is worn for the purpose of preventing static electricity and preventing dust.

[0003] The dust-proof clothing worn in such a high-class clean room prevents the dust from the clothes and the human body is a large source of dust. The structure is such that dust does not get out of the dust-proof clothing.

[0004] In addition, the anti-static clothes are designed to prevent micro dust in the environment from being attracted by the Coulomb force.

[0005] The cloth used for the dust-proof garment is generally made by weaving conductive fibers in a lattice or stripe pattern with long fibers of polyester or the like, so that static electricity generated by friction between the cloths of the dust-proof garment or underwear. Is to be removed from the conductive fiber by a weak corona discharge, that is, antistatic by so-called self-discharge.

[0006] Also, clothes, not limited to dust-proof clothing, are not made of one piece of cloth, but may include sleeves, front body, back body,
It is realized by cutting the collar and other parts and sewing them. The sewn portions, cuffs, hem, etc. of each part have a double structure to prevent dust generation from the cut material portion.

[0007]

However, even a dust-proof garment in which conductive fibers are woven is not intended to be removed by conduction by increasing the electric conductivity, so that a certain level of static electricity remains. In a high-class clean room, there is a problem that minute dust adheres to dust-proof clothing and becomes a source of contamination, or causes noise to cause malfunction of a computer and destruction of a semiconductor element.

[0008] In addition, since the purpose of the dust-proof garment is not to prevent the electrostatic charge of the human body but to prevent the garment itself from being charged by friction, the conductive fiber is exposed to the outside of the cloth. It is woven and does not attempt to leak static electricity generated by the human body during conduction by conduction. For this reason, in the conventional dust-proof clothing, since there are few exposed portions of the conductive fiber inside the cloth, it is difficult to completely remove the static electricity generated between the human body and the dust-proof clothing, and furthermore, the conductive fiber is grounded. However, there is a problem that the structure is not always such that the potential is 0 V.

Further, the above-described double-structured suture portion is effective from the viewpoint of dust prevention, but on the other hand, the conductive fibers are cut off, and places where electrical connection is not made occur everywhere. For this reason, there is a problem that the static electricity charged on the dustproof garment is not completely removed.

[0010] In addition, even in the storage of the dust-proof garment, there is a problem that the remaining static electricity is hard to be removed, and the static electricity remains when next worn.

In view of such circumstances, an object of the present invention is to provide a dustproof garment having improved antistatic properties and dustproofness.
