Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an improved hat for dustproof clothing mainly for wearing in a clean room.

(Prior art) Recently, in IC production plants, food processing, pharmaceutical production plants, biological research laboratories, etc., the room is always kept clean to prevent dust, viruses, bacteria, etc. from adhering to the products. In many cases, they own the so-called clean room equipment that can be kept at.

However, the secretions of the human body entering the room and working, and dust adhering to clothes often contaminate the above products, and as a means for coping with this, it is common to wear dustproof clothes. ing.

The material of this dustproof garment is a highly dense woven fabric mainly using synthetic fiber filaments such as polyester, nylon, etc., and a fabric which minimizes breathability so that dust is hard to adhere and dust is not discharged is used. . In addition, these dustproof garments should be subjected to antistatic processing to prevent dust from adhering to the outside air due to static electricity, or conductive fibers should be placed vertically or horizontally or both vertically and horizontally so that the generated static electricity can be leaked. Frequently arranged fabrics are often used.

However, in the above-mentioned clean room, the dust generated from the human body cannot be prevented only by these dustproof clothes, and the hat, gloves, shoes, etc. must also have the dustproof characteristics of the dustproof clothes described above. is there.

Among them, various types of hats are already available, which are made of the same material as the above dustproof garment. As in the case of the present invention, a cap-shaped inner cap has conventionally been put on the inside of the cap body in order to prevent the hair, dandruff, etc. from falling off. It was independent and had no effect of the inner cap of the present invention.

(Problems to be solved by the present invention) The hat for the dust-proof clothing has a hat with respect to the actual head size in order to minimize the variety in size and not to disturb the hair style. Often designed to allow for size.

Therefore, the conventional hat has a drawback that when the head is shaken up and down and left and right in a state of wearing the hat, the hat does not follow the movement of the head, and when the head is moved, the hat shifts and a part of the hat obstructs the viewing angle. Therefore, when using a conventional hat, work efficiency decreases,
The fact is that workers dislike wearing hats even if they are obliged to wear hats.

(Means for Solving Problems) The present invention relates to an improvement of the above-described conventional hat,
Even when the head is shaken up and down, left and right with the cap on, the hat moves along with the head, and a part of the hat does not cover the eyes and does not obstruct the viewing angle. Is.

That is, the present invention relates to a dustproof clothing cap that can cover the head and expose the face, and is composed of an outer cap and an inner cap inside the outer cap, and the periphery of the upper end of the inner cap is connected to the inner side of the outer cap. The present invention relates to a hat for dustproof clothing, which is characterized in that

In the present invention, the inner hat has both the effect of preventing hair and dandruff from falling off as described above and the effect of preventing the outer hat from slipping during wearing.

Examples of means for joining the outer hat and the inner hat include ordinary sewing, joining with an adhesive, joining with ultrasonic waves or high-frequency welders, and the like. The inner hat in the present invention is an outer hat, a fastener, and a magic fastener (registered trademark).
(“Velcro fastener (registered trademark)”) or the like so as to be detachably coupled.

(Embodiment) Hereinafter, details and effects of the present invention will be described based on an embodiment of the drawings.

FIG. 2 is a front view of the dustproof garment when the worker wears the dustproof garment, and shows a state in which the hem of the hat 1, that is, the shoulder panel is put in the dustproof garment 10.

Further, in this figure, the worker wears dustproof gloves 20 and shoes 30.

FIG. 1 shows an embodiment of a dustproof clothing cap 1 according to the present invention. The cap 1 is composed of an outer cap 4 and an inner cap 5, and the inner cap 5 is connected to the inside of the outer cap 4 so as to be integrated at the position of the upper periphery L of the outer cap 4. The inner cap 5 to be joined may have a form in which the upper part is opened as shown in FIG. 3 (A), or a form in which the upper part is exposed and only the face is exposed as shown in FIG. 3 (B). .

These inner caps 5 are connected to the upper periphery L of the outer cap 4 by the means described above, but usually by sewn together the broken line 1 portion. In the mode of the inner cap 5 in FIG. 3 (A), the upper head contacts the inner side of the cloth of the outer cap 4, and in the mode of the inner cap 5 in FIG. 3 (B), the upper head is the cloth of the inner cap 5. It comes into contact with.

The open peripheral portion 6 of the inner cap 5 is subjected to three-winding treatment or piping treatment except for the upper edge, and when a shirring is formed by putting an elastic cord or the like therein, it fits around the face of the worker,
The entire hat 1 is fixed and does not move.

The material of the outer hat 4 is a polyester or nylon filament yarn or false twisted yarn of 50 to 150 denier, and a plain weave, a twill weave, a twill weave, etc., with a warp and transverse density of 100 / inch and 60 and 60 / inch, respectively. It is preferable that the twill weave structure has a finer eye. Further, the above-mentioned filament yarn is a type of yarn in which polyethylene glycol or the like is kneaded in the polymer stage (“Parel” (registered trademark) manufactured by Toray Industries, Inc.)
Or a conductive fiber (carbon, carbon fiber or metal fiber, or a substance in which these substances are put in or coated) in the warp yarn, the weft yarn, or both at appropriate intervals. It is preferable to use a cloth that is woven to impart antistatic property. At this time, as the antistatic property, it is preferable that the friction electrification voltage is 3000 V or less under the environment of at least 30% RH and 20 ° C.

On the other hand, as for the shape of the hat, as shown in FIG. 2, the seams and edges of each piece are wrapped with binder or with three windings or another cloth so that there is no fraying of the yarn at the cut end. . In addition, the front mating portion is doubled so as to be overlapped in order to prevent dust generated from the collar of the dustproof garment, and is fastened with fastening materials 8 and 9 such as Velcro (registered trademark).
A skirt-shaped shoulder panel 2 is attached to the hem of the outer hat 4. The shoulder panel 2 may be placed inside the garment as shown in FIG. 2, but may be placed outside the garment. Although not shown in the figure, a type without the skirt-shaped shoulder panel 2, that is, a type in which the neck portion is made into a belt shape to fit around the neck, or is detachable with a collar and a fastener of clothes is used. Good. Further, the collar 3 in FIG. 1 is mainly provided in terms of design, and does not necessarily have to be provided.

Of the inner cap 5 material may be either of a fabric with a knitted or stretch, it is preferable to use a material with the somewhat stretch in thin software basis weight ^{50g / m 2 ~150g / m 2} .

If the fabric weight is 50 g / m ² or less, the eyes are not coarse, and if it is 150 g / m ² or more, the head becomes stuffy during use. As for the functionality, if the one with the antistatic property is used like the outer cap 4, the dust can be adsorbed and the generation of dust can be prevented, but conversely, when the material that easily generates static electricity is used. Is expected to have the effect of suppressing dust generation by attaching hair, dandruff, etc.
It is preferable to properly use these depending on the application.

As the material, woven fabric using polyurethane-based elastic yarn,
Alternatively, tricot or mesh tricot, ordinary polyester or nylon processed yarn, etc. can be used.

(Operation) As for how to wear the hat for dustproof clothing according to the present invention, first, the outer hat 4 is made to hang down on the face, and then the inner hat 5 is put on.
As for how to put the ears on, it is better to put the ears in the inner hat 5 for better stability of the entire hat. Next, the outer cap 4 is put upside down later with the part of the inner cap 5 that contacts the forehead as a fulcrum. After that, the position of the entire hat 1 is adjusted and the fastening members 8 and 9 are appropriately joined. When the worker wears the main hat as described above, the outer cap and the inner cap are integrally mounted on the head so that the cap does not shift, and the worker can feel a comfortable wearing feeling. Especially when the inner hat is made of a soft and slightly stretchable material, it fits to the ears, cheeks and head, and the cloth does not rustle and rustle.

(Effects of the Invention) With the hat for dustproof clothing according to the present invention, even when an operator shakes his / her head forward, backward, leftward or rightward, the periphery of the face opening of the hat does not shift over the face (eye part) and is covered.

In addition, the original purpose of dust-proof clothing hats is to be dust-proof and dust-generating, which is almost the same as or better than when a separate type made of the same material (type with outer hat and inner hat separated) is used. Has the effect of.

It is considered that this is because the entire hat is fixed to the head, so that dust inside the hat does not project to the outside of the hat due to the pump effect unlike the conventional hat.
