Description

[Detailed description of the invention] Industrial application field This invention is worn by workers and other visitors working in industrial clean rooms such as those in the electronic parts industry, or bioclean rooms such as those in the food and pharmaceutical industries. For use in clean rooms, used to completely cover and seal the entire body of workers to prevent waste products and germs emitted from the skin of workers, and dust emitted from underwear from leaking into the clean room. Regarding dust-free clothing, more specifically, it has an excellent effect of sealing the wearer's body to prevent dust from leaking, and has a structure that reduces the feeling of a foreign body during each movement or work of the wearer, and is easy to put on and take off. The present invention relates to dust-free clothing for clean rooms that has been improved.

Prior Art In clean rooms, the presence of dust of 0.1 to 0.01 microns is also considered a problem. In short, dust emitted from human skin or the underwear worn by people is a big problem, so those entering the clean room and the workers must be sure to wear dust-free clothing and be extremely careful not to leak dust. It is enforced.

As a material for dust-free clothing, polyester-based synthetic fiber fabrics with excellent antistatic properties, sweat absorption, stain resistance, and antistatic properties have been developed and are widely used.

Traditionally, the structure and format of dust-free clothing was so-called tsukuri-bukuro, in which the upper and lower garments were sewn together.
Additionally, dust-free clothing with a hood cap is common. In this case, a detachable opening/closing section with a fastener that can be opened and closed is provided approximately in the center of the front body of the jacket, and the wearer's body is inserted into and out of this section to put on and take off the jacket. The food cap is
It was constructed separately from the jacket.

Recently, an opening/closing part with a zipper has been installed along the seam between the front body and back body at the inner thigh of the lower garment, from the inseam to both hems, and the wearer's body can be put on and taken off by entering and exiting from here. Dust-free clothing has also been developed in which the hood cap is sewn integrally with the jacket.

Problems to be solved by this invention () When the above-mentioned dust-free clothes have a structure in which a detachable opening with a fastener is provided in the center of the front part of the jacket, the conditioned air in the clean room is generally used for work. The dust emitted from the skin and underwear of workers is designed to hit the backs of workers, and whenever the workers move, the dust emitted from their skin and underwear can penetrate through small gaps such as fasteners and onto the most important electronic components that are being worked on. There is a problem of leakage and dissipation into the room towards the room. Furthermore, since the jacket and the hood cap are constructed as separate bodies, no matter how carefully the overlapping portion of the two is treated, it is still far from completely sealed and there is a problem in that it is impossible to prevent dust from leaking.

In addition, the front side of clothing is prone to wear due to rubbing against something during the worker's movements and work.
They tend to be easily damaged or soiled. This tendency is particularly strong when there is a fastener etc. Temporarily 0.1
Even if a micron-sized hole (damage) occurs, it will be useless as a dust-free garment, so it is desirable that the front body has a structure that has no seams or fasteners, etc., so these points become a problem. ing.

() In this respect, the above-mentioned dust-free clothing, which has a fastener-equipped opening and closing part that extends from the crotch to both hems, has a more advanced construction in terms of sealing performance. It can be a family.

However, there is a problem in that it is extremely troublesome and time-consuming for the wearer to put on and take off the wearer. Wearers of dust-free clothing take an air shower to cleanse themselves at the entrance to the clean room, which requires a release time of about 1 minute 20 seconds to 1 minute 30 seconds for putting on and taking off. Not being able to meet the demands is a serious problem.

Furthermore, it cannot be denied that fasteners and the like provided on the inner thighs are easily worn out by rubbing against the crotch every time a worker or the like wearing them walks, and that holes (damage) of about 0.1 micron are easily formed.

In addition, inseam fasteners, etc., rub against the inner thighs every time the worker wears them, making them feel like a foreign body. Since it is inevitable that the wearer will feel a foreign body when it comes into contact with the skin, it has a poor feel and is extremely uncomfortable to wear, so there is a problem that it is not very suitable for workers.

Means for Solving the Problems As a means for solving the above-mentioned conventional problems, a preferred embodiment of the dust-free clothes for clean rooms according to this invention is shown in FIGS. 1 and 3 of the drawings. This is a continuation garment in which an upper garment 1 and a lower garment 2 made of static-eliminating synthetic fiber fabric are sewn in series, and a hood cap 3 that covers the face and head from the neck up is sewn integrally with the upper garment 1 for use in clean rooms. In the dust-free clothes, a fastener 8 is placed along the seams of both sleeves 4, 4 from around the middle of the left and right shoulder flaps on the back of the jacket 1.
An opening/closing part 7 for attachment/detachment which can be freely opened/closed by means of, for example, is provided.

At the back of the hood cap 3, a detachable opening/closing part 9 which can be freely opened and closed is provided upward with one end extending from the opening/closing part 7 of the jacket 1, and this opening/closing part 9 is connected to the Velcro tape (registered trademark) 11. ,12
It is configured to be opened and closed by a flap 10 that can be attached and detached.

Function The wearer (worker, etc.) of this dust-free clothing pulls the slider 8a of the fastener 8 to open and close the attachment/detachment opening/closing part 7, and puts the garment on and off in the same manner as putting on so-called continuous clothing. Take off. At the same time, the head cap 3 can be put on or taken off by putting the head in and out of the head cap 3 through the opening/closing part 9 for putting it on and taking it off, which satisfies the requirement for quick putting on and taking off the head cap.

Close the fastener 8 of the attachment/detachment opening/closing part 7, and
When the flap 10 of the headcap 3 is closed, the worker's body is completely covered with dust-free clothing and is in a sealed state.

There are no fasteners or seams on the front sections of the dust-free clothing top 1 and bottom clothing 2, and the openings 7 and 9 for putting on and taking off the dust-free clothing are provided on the back side, making it easy for workers to wear them. Dust will not leak to the front side no matter what kind of movement or working posture the person uses. Therefore, even if the design is such that the conditioned air in the clean room hits the worker's back, there will be no problem at all.

The fastener 8 of the attachment/detachment opening/closing part 7 provided on the back of the jacket 1 does not cause any sensation of skin contact, and almost no sensation of foreign body, regardless of the behavior or working posture of the worker wearing it. Since there is no,
It's extremely comfortable to wear.

Embodiment Next, the hood shown in FIGS. 1 and 2 will be explained.

This dust-free clothing consists of an upper garment (1) and lower garments (trousers) (2) made from polyester static-eliminating synthetic fiber fabric.
It is formed as a continuous garment made by sewing a series of .
A hood cap 3 that covers the wearer's face and head above the neck is also sewn integrally with the upper neck portions of the front body and back body of the jacket 1.

The waist, which is the boundary between upper garment 1 and lower garment 2, is approximately 2 cm wide.
A diaphragm is added to the inner rubber 18. Further, the seam between the hood cap 3 and the jacket 1 is covered with a collar 19 having a width of about 3.5 cm. The cuffs 4a, 4a of both sleeves 4, 4 of the jacket 1 are configured as openings into which several rubber shear rings are inserted. Further, the trouser hems 5, 5 of the lower garment 2 are also constructed with rubber shearing as a diaphragm to prevent dust from leaking.

In short, the front bodies of the upper garment 1 and the lower garment 2 are constructed without any seams or fasteners other than seams that may cause gaps. The front side of the hood cap 3 is simply provided with a small horizontally long rectangular window 6 through which only the wearer's eyes are slightly exposed (FIG. 1).

On the other hand, on the back of the jacket 1, a long linear opening/closing part 7 is provided at a position along the seams of both sleeves 4, 4, passing through the middle of the left and right shoulder flaps, and this has a double-opening opening/closing part 7 on the left and right sides. It is configured to be openable and closable by two fasteners 8, 8 having a slider 8a. The starting ends of the two fasteners 8, 8 are located approximately at the center of the back (FIG. 2).

At the back of the hood cap 3, there are two fasteners 8, 8 in the opening/closing part 7 for putting on and taking off the jacket 1.
An attachment/detachment opening 9 is provided in the form of a vertical line starting from one end and extending upward, and in short, the two attachment/detachment openings 7 and 9 are formed into an inverted, generally T-shape. The opening 9 for attaching and detaching the hood cap 3 is configured to be opened and closed by overlapping flaps 10. The flap 10 is configured to be detachable using magic tape (registered trademark) 11 and 12. Further, a band 15 that tightens in the circumferential direction is provided at the upper end of the opening/closing part 9 for attachment and detachment, and this is also configured to be attached and detached using magic tape (registered trademark) 16 and 17.

Therefore, a person who wishes to wear this dust-free clothing first pulls the slider 8a of the fastener 8 to widen the opening/closing part 7 to the left and right. Furthermore, the hood cap 3 is opened by peeling off the magic tape (registered trademark) 11, 12 of the flap 10 and opening/closing part 9 for attachment/detachment. Then, in the same way as putting on a so-called continuous garment, first put both feet into the jacket 2 and pull it up, then put your hands into both sleeves 4, 4 of the jacket 1 and put on the jacket 1. Furthermore, the user puts his/her head through the attachment/detachment opening/closing part 9 of the hood cap 3 and puts it on, and then pulls the slider 8a of the fastener 8 to close the attachment/detachment opening/closing part 7 from the left and right sides. Furthermore, by fixing the flap 10 with Magic Tape (registered trademark) 11 and 12 and fixing the band 15 with Magic Tape (registered trademark) 10 and 17, the attachment/detachment opening/closing part 9 is closed and the wearing is completed.

In order to improve the sealing performance of the fastener 8, the upper fastener claw 8c of the fastener 8 is folded back and sewn deep into the fold 20 as shown in FIG. It is configured to be covered. Instead of the fastener 8, seam fasteners, snap hooks, magic tape (registered trademark), etc. can also be used.

Effects of the present invention As detailed above in conjunction with the examples, the dust-free clothes for clean rooms according to this invention have the following features:
Anyone can easily put on and take off the jacket 1 in the same way as putting on and taking off regular clothes through the opening and closing parts 7 provided from the left and right shoulder flaps of the back of the jacket 1 along the seams of both hems 4 and 4. Since it can be used, it is easy to use and can be quickly attached and detached.

In addition, the front side (front body) of upper garment 1 and lower garment 2
Because the structure has no gaps such as fasteners or seams that allow dust to leak in the micron scale, no matter what kind of behavior or working posture the worker wears, the clothes will remain dust-free. There is no risk of the dust inside leaking to the front side, and the sealing performance is extremely high. Especially in light of the fact that the air conditioned air in the clean room is designed to hit the backs of the workers, it is a logical structure to prevent dust leakage, and is suitable for manufacturing electronic parts, food products, etc., which are extremely sensitive to dust. Its performance and quality are extremely high as dust-free clothing for pharmaceutical and other biotechnology applications.

In addition, since the flap 10 for opening and closing the attachment/detachment opening 7 and its fastener 8 or the attachment/detachment opening 9 of the hood cap 3 are all provided on the back side of the clothing, the wearer hardly feels like a foreign body. It is comfortable to wear, and has excellent workability.
