Description

{Cleanroom uniform} with easy ventilation at night.

The present invention relates to an anti-vibration garment which is excellent in air-tightness of a dust-proof garment and is easily ventilated at night, provided with ventilation means for ventilating the interior of the dust-proof garment so that the wearer can work over a long period of time.

The present age is the age of scientific industry and high technology industry, and advanced products to be manufactured require production environment of ultra-high definition, high integration, high purity and sterilization to improve product performance and manufacturing yield.

These production environments are used for bioclean room system to prevent biological pollution in medicine, pharmaceutical, food, genetic engineering, and industrial clean room system to prevent particle contamination such as semiconductor, electronics, precision machinery, And it is still in progress.

Particularly, a clean room of a high-tech industry and a developed production environment, that is, a clean room, supplies clean air through an upper filter to continuously remove particles generated inside, and guides the clean air to the lower side of the grating pad. In the downstream direction of the laminar flow type.

In addition, as described above, the importance of the management of clean rooms, which are strictly required to be cleaned, and cleaners, which are used in cleanrooms, are emphasized.

Among the consumables used in the clean room, there is a dustproof garment to be worn by a worker. This dustproof cloth prevents the various particles generated from the human body of the worker from flowing out to the workpiece upper body to prevent contamination and damage of the workpiece body by the particles .

The abovementioned anti-vibration clothing is provided with a material of a material having a small oscillation rate, which is used in conjunction with a trend toward refinement of high-tech products, and is formed so as to narrow a sleeve or a joint so as to increase the airtightness of the inside thereof .

A stand collar 14 is formed on the upper portion of the body portion 10 corresponding to the neck portion of the human body. A portion of the stand collar 14, from the upper side thereof, And a vibration-proof window 16 formed to cover the window 16 is detachably provided.

However, since the air pressure in the anti-vibration cloth is increased or decreased as compared with the air pressure of the clean room due to the movement of the operator, the dustproof clothing of the above-mentioned configuration has a limitation that the particles generated inside the anti-vibration clothes are released through the gap in the sleeve or the seam.

Particularly, the body 10 and the vibration-proof window 16 are made to have different sizes according to workers to be worn. Therefore, the connecting portion between the body 10 and the vibration- The portion of the stand collar 14 and the corresponding portion of the vibration-proof window 16 do not meet the mutual specifications. The gap between the stand collar 14 and the vibration-proof window 16 is larger than the other portions.

In the process of connecting the body 10 and the vibration-proof hair 16, the hair of the worker is frequently exposed to the outside, and after the joint, And the like.

This causes particles generated in the interior of the room to be released to the outside, thereby causing problems such as poor product and manufacturing yield.

In order to solve such a problem, Korean Patent Laid-Open Publication No. 10-2002-82617 discloses another prior art as shown in FIG. 2, and the related art has a structure in which a worker wears a dust- The present invention relates to a set of a dust-proof cloth which can effectively prevent particles generated from a human body part from being discharged to the outside. Wherein the body portion and the vibration damping protrusion are integrally formed, and the opening portion is formed integrally with the dustproof case, And extends to the front surface of the simulator.

Accordingly, since the dust cover covering the neck portion of the human body and the neck portion of the human body is integrally formed, the degree of the particles generated from the human body portion of the operator to the workpiece through the neck portion is remarkably reduced It is possible to prevent contamination and damage of the workpiece, thereby improving the quality of the product and the yield of the product.

However, in such a conventional anti-vibration clothing, when the wearer performs an action such as turning the neck, raising the arm, raising the leg, etc., as the body part and the dust-proof body are integrally formed, In the case of a worksite in which foreign substances are exposed to the outside and the foreign substances in the interior of the room are discharged to the outside or dust is blown out, there is a disadvantage that the foreign substances are introduced into the inside of the anti-vibration clothes.

In addition, the conventional anti-vibration clothes can not be discharged to the outside because the sweat or moisture of the wearer can not be discharged to the outside so that it can be used for the purpose of use. Therefore, when the work is carried out for a long time, it is easily exhausted or moved outside the clean room, There was a hassle to do.

Of course, a method for solving the aforementioned problem of ventilation by varying the fabric of the dustproof clothing itself has been disclosed, but such a dustproof garment is accompanied with a problem that the unit price of the dustproof cloth is high, so that it can not be popularized.
